The heating and cooling heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source, and is also a new energy technology that has attracted a lot of attention worldwide. It differs from the well-known mechanical equipment, which can increase the potential energy"Pumps"; A heat pump usually first extracts inferior heat energy from natural air, water or earth, then performs work by electricity, and then provides people with available energy that can be used. of high quality thermal energy.
What is the working medium of the heating and cooling heat pump?
What role does the heating and cooling heat pump play?
What do you know about heating and cooling heat pumps?
The working medium of the heating and cooling heat pump used to be Freon, but since Freon adversely affects the Earth's atmospheric ozone to protect the Earth's ecological environment, in addition to improving the cooling coefficient of the heat pump and effective use, science is also committed to new technologies in various countries. With the development of quality, the working fluid was used as a replacement for Freon. However, the work equipment of most Chinese manufacturers today is still R22, and the era of using environmentally friendly work equipment R417A and 134A has not yet arrived. Some countries, such as Japan, have taken the lead in using CO2 as a working medium to avoid damaging the ozone layer. (Therefore, the copper pipes must be firmly connected during installation to prevent R22 from leaking.) In addition, the above R22, R417A, 134A and CO2 do not harm the human body. Even if there is a leak, all the equipment is still safe.
The low temperature heat sources normally used in heat pumps for heating and cooling are the media around us. Air, river water, seawater, municipal wastewater, surface water, groundwater, treated water, fire pits or working fluids, which are discharged from industrial production plants these working fluids often have similar temperatures to the surrounding medium. The operating principle of the heating and cooling heat pump is the same as that of the compression chiller. In order to fully exploit its efficiency, the small air conditioner is cooled with the same equipment in summer or heated in winter. When heating in winter, the evaporator and condenser in the air conditioning system are exchanged via a switching valve.
Heat pumps for heating and cooling are an intelligent, efficient and versatile solution for year-round heating, cooling and hot water supply solutions. In addition to their flexibility and wide application, they are energy efficient and environmentally friendly, with advanced EVI technology and green refrigerant R32/R410A. So you can enjoy a comfortable home and save energy at the same time.
JNOD insisted on developing with technological innovation, it had several nationally famous technicians and had invented several product patents. The company has strictly implemented the international ISO quality management system, and the products are of reliable guaranteed quality.
Heating and Cooling Heat Pump is a central air-conditioning unit that uses air as a cooling (heat) source and water as a circulating medium to transfer energy. Its advantages are that it is easy to install and use, and it can be used after connecting to the power supply, saving a complex cooling water system and a boiler heating system.
Compared with other products of the same type, why is Heating and Cooling Heat Pump cost-effective?
What are the common Heating and Cooling Heat Pumps on the market?
What to look for when choosing a Heating and Cooling Heat Pump?
Compared with electric boilers, Heating and Cooling Heat Pump can save more than 50% of power consumption, and reduce the trouble of frequent replacement of electric heating tubes; Compared with traditional coal boilers and oil-fired boilers, Heating and Cooling Heat Pump is pollution-free, emission-free, and safe , eliminating the need for annual routine security inspections, eliminating the need for professional boiler workers, fully automatic temperature control, and significantly reducing operating costs by more than 50%. Heating and Cooling Heat Pump completes a heat pump for heating and cooling needs in a particular field. Generally speaking, Heating and Cooling Heat Pump uses specialized heat pump compressors, special refrigerants and systems.
There are many types of heat pump water heaters on the market, mainly including three series of solar boost type, water source and air source. Solar-assisted heat pump is a heat pump technology that combines heat pump and solar energy technology; water source heat pump uses a certain temperature water source (above 20 ℃) as a heat source and uses refrigerant as a medium to absorb the heat in the water source and then compress it by a compressor. For heating, exchange heat with cold water through a heat exchanger to achieve the purpose of heating and producing hot water. The water source heat pump must have a water source with a certain temperature and flow; the air source heat pump obtains heat from the air in a similar way to the water source heat pump to heat water. Among the three types of heat pumps, the air source heat pump is subject to the least restriction and has the largest development space.
Whether the Heating and Cooling Heat Pump saves electricity has a lot to do with outdoor temperature, building insulation, user usage, equipment purchase and installation. If you want to save more electricity, users not only need to carefully select air source products, such as buying big brands as much as possible, finding professionally qualified installers for installation, etc., but also mastering the correct air source heat pump heating method, in order to achieve high efficiency and energy saving.

DATE: April 15th ,2022
Winter has arrived, and people tend to use heat pumps as heating machines. If the heat pump unit can be installed reasonably, the service life and heating capacity of the heat pump will be improved. Let Jnod tell you how to install it, see below:
1. Unit installation location planning
1) The installation requirements of the heat pump main unit are similar to the installation requirements of the outdoor unit of the air conditioner. It can be installed on the roof, balcony, and ground. The air outlet should avoid the windward direction.
2) The distance between the main unit (wind from the side) and the surrounding walls or other obstructions should not be too small. There should be no obstructions within 1 meter of the air outlet, and ensure that the heat exhaustion and suction of the heat exchanger are not hindered.
3) There should be no obstructions within 1 meter of the air inlet of the main unit (top air outlet), and no obstructions within 2 meters of the air outlet to ensure that the heat exhaustion and suction of the heat exchanger of the main unit are not hindered.
When the unit is installed under the eaves or there are horizontal obstacles above the unit, the installation location of the unit must be in a well-ventilated place, otherwise it is easy to short-circuit the air flow, resulting in poor heat dissipation capacity of the unit.
2. Unit installation environment control
1) Try not to place it in direct sunlight.
2) Not on the window sill of the bedroom or near the bedroom.
3) There is enough distance between the air inlet and outlet to facilitate heat dissipation.
4) Places that can withstand more than 2-3 times the weight of the outdoor unit.
5) A place where there is no oily smoke or other corrosive gas.
6) A place that does not affect other factors or the environment.
The heat pump water heaterabsorbs the low-temperature heat in the air, vaporizes the cold medium, and then compresses it through the compressor to increase the temperature, and then converts it through the heat exchanger to heat the water, and the compressed high-temperature heat energy is used to heat the water temperature.
What is the difference between a heat pump water heater and an air conditioner?
What are the advantages of heat pump water heater and compared with gas water heater?
What are the advantages of heat pump water heater compared to electric water heater?
When a general air conditioner is refrigerating, it absorbs the heat in the room through the phase change of the refrigerant in the evaporator (liquid to gas), and then realizes cooling through the heat release of the outdoor condenser. His heat exchange equipment is mainly finned heat exchangers. The heat pump water heater converts the low-grade energy in the air into high-grade energy that we can use. The heat is obtained by absorbing heat from the air through the phase change (endothermic) of the refrigerant in the evaporator, and then releasing heat through the indoor condenser (or jacket heat exchanger). This is his heating state. Its cooling is the same as that of general air conditioners, except that the heat exchanger may be different. General air conditioners use ordinary finned heat exchangers.
Gas water heaters heat the water temperature by burning combustible gas, and at the same time, will produce greenhouse gases such as carbon dioxide. If the continuous large amount of carbon dioxide on the earth exists in the air for a long time, it will produce a greenhouse effect on the earth's environment! The heat pump water heater only heats the water temperature with the heat in the air, and will not emit any toxic and harmful gases. In the era of energy saving and emission reduction, it is a water heater that is truly energy-saving and environmentally friendly. Secondly, gas water heaters may leak gas and cause human carbon monoxide poisoning accidents. Therefore, the safety of empty heat pump water heater is better than that of gas water heater.
We can compare heat pump water heater with electric water heater. Electric water heaters are heated with electric heating rods. The heat pump water heater heats the water temperature by absorbing heat from the air. The heat generated by the heat pump water heater consumes 1 kWh of electricity equivalent to the heat generated by the electric water heater consuming 4 kWh of electricity. In terms of energy saving, heat pump water heaters are far more energy efficient than electric water heaters. Second, in terms of security. The heat pump water heater just transfers the heat after compression heating to the water tank for heating, so the water and electricity are completely isolated. The electric water heater electric heating rod is directly heated in the water. Therefore, leakage accidents are easy to occur!
Guangdong JNOD New Energy Technology Co., LTD. is committed to providing customers the best hot water & heating solutions with our heat pump products, focusing on the latest technologies, strive for outstanding quality in our products and customer service.
In fact, the working principle of the Heat Pump Hot Water Heater does not differ significantly from the working principle of our air conditioning system. However, our household air conditioners use the cold end (evaporator) of the cooling circuit system; In contrast, heat pumps use the hot end (condenser) of the circulatory system.
What is the spring of air simultaneous heating and cooling heat pump for homes?
How does the Heat Pump Hot Water Heater provide hot water?
What is the current market situation for Heat Pump Hot Water Heaters?

● Adaptive thermostat technology of ±1℃
The user feels more comfortable with small temperature fluctuations.
The basic principle of heat pump water heater: It mainly consists of compressor, heat exchanger, axial fan, heat storage water tank, water pump, liquid storage, filter, electronic expansion valve and electronic automatic control. After switching on the power supply, the axial fan starts running, the outside air flows through the evaporator for heat exchange, and the reduced temperature air is expelled from the system by the fan. A kind of low pressure working medium gas is compressed into high temperature and high pressure gas and fed to the capacitor. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and fed to the consumer for use. The working medium is cooled to a liquid and the liquid expands. After the valve is throttled and cooled, it flows back into the evaporator. This cycle works repeatedly, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the water tank for heat preservation gradually rises and finally reaches about 55°C, which is just suitable for people to take a bath.
Heat pump water heaters are a new thing on the market, and consumer awareness of this is still very low. There are many people who think that it is impossible to get three parts heat with one part heat, and the same applies to other products related to the application of heat recovery technology, although the popularity of heat pump air conditioners was very high.
People's understanding is limited only to the fact that air conditioning is a large electricity consumer, but they do not know that it is more energy-saving than the coal-fired ball furnace. As some larger shopping malls have not yet sold air-powered water heaters, consumer awareness of air-powered water heaters is still very low.
In order to meet these growing requirements, Guangdong JNOD New Energy Technology Co., LTD. has various heat pump water heaters, which allow to increase the products and make them more effective, reliable and consistent.
In recent years, the potential energy of the sports industry under the national fitness, and favorable policies such as swimming into the high school entrance examination sports, the constant temperature swimming pool was once in short supply, and the Swimming Pool Heat Pump was out of stock.
What is the first stage of the workflow of Swimming Pool Heat Pump?
What is the second stage of the workflow of Swimming Pool Heat Pump?
What should we pay attention to when using Swimming Pool Heat Pump?
In the first step, the indoor hot and humid air in the swimming pool first exchanges heat with the outdoor fresh air through the heat exchanger to become warm and humid air, and then the warm and humid air flows through the evaporator, the temperature drops, and the water vapor condenses into cold water droplets and is separated from the air. Make the air dry and realize the function of air dehumidification; at the same time, the heat energy (latent heat and sensible heat) is released in the process of air cooling, water vapor condensation and cooling are absorbed by the refrigerant.
In the second step, the heat energy absorbed by the refrigerant first (latent heat) heats the pool water through the heat exchanger to realize the pool water heating function: the residual heat (sensible heat) passes through the air condenser to heat the cooled indoor air to realize the air insulation function. In the severely cold winter, when the energy available for the heat pump to extract in the air is too small, and the heat energy recovered by the heat pump is not enough to meet the requirements of the indoor air temperature, the auxiliary air heater is added to supplement the heat energy required for the indoor hot air. The Swimming Pool Heat Pump only needs to provide its own operating power, that is, it runs continuously according to the above working procedures, and achieves a harmonious balance of the three functions of pool water heating, air conditioning and dehumidification with low energy consumption.
1. When maintaining and cleaning the Swimming Pool Heat Pump, make sure that the Swimming Pool Heat Pump is in a power-off state. In addition, when the heat pump is not in use: the power supply should also be cut off.
2. Do not use gasoline, Tianna water, volatile oil, solvents and other chemicals, or liquid pesticides on the Swimming Pool Heat Pump, otherwise it may cause parts to crack and deform.
3. The area around the Swimming Pool Heat Pump should be kept dry and well ventilated.
4. Regularly clean the air-side heat exchanger to maintain a good heat exchange effect. If the shutdown time is long, the water in the pipeline of the unit should be drained, the power supply should be cut off, and the protective cover should be put on. When it is necessary to use it again, the system must be thoroughly checked before turning it on.

The operating principle of heat pump water heaters is very similar to that of air conditioning systems. It consumes a small amount of electrical energy to get the compressor running. The working fluid is compressed by the compressor into a liquid state with high temperature and high pressure, and then enters the condenser to release heat to heat the water. By circulating and heating in this way, the water can be heated from 50°C to 65°C.
What are the main components of heat pump water heaters?
How does the heat pump water heater work?
Why should the heat pump water heater be green?
Four main components of refrigeration technology: evaporator, compressor, condenser and throttling device.
Three stable parts: liquid storage tank (compressor), expansion valve (capillary tube), dry filter (filtering water and impurities)
A large piece of defrosting: four-way valve
Break through traditional energy conversion theory to achieve high energy efficiency:
When operating the heat pump, the working medium in the evaporator can absorb the energy QA stored in the ambient medium;
And starting the system must consume energy, that is, the power consumption of the QB compressor;
At the same time, the heat emitted from the working medium to the high temperature medium in the condenser is QC;
After the compressor input work starts the system, the mechanical kinetic energy becomes thermal energy. The energy output of the heat pump is thus the sum of the work done by the compressor QB and the heat absorbed by the heat pump from the environment QA; Enter a QB to get QB+QA and break the traditional bottleneck that conversion between different energies cannot achieve full efficiency; Heat pump technology is more energy efficient.
heat pump water heaters work according to the "reverse carnotic" principle, specifically the "outdoor unit" as a heat exchanger absorbs heat from the outside air, heats the low boiling working medium (refrigerant) and evaporates it, and the refrigerant vapor The water is compressed and heated by the compressor and enters the water tank, and the water in which the heat is released is condensed and liquefied and then throttled and pressurized to return to the outer heat exchanger to enter the next circuit. The heat pump water heater simply absorbs the heat in the air to heat the water, and the air that has absorbed the heat can also be used in the kitchen to solve the problem of stuffy heat.
The heat pump water heater has energy saving functions.
The biggest advantage of the heat pump water heater is undoubtedly the energy saving. The low-temperature thermal energy in the air is converted into high-temperature thermal energy by the compressor. Based on the same amount of hot water generation, the energy saving is maximized compared to the water heater with electric heating, and the cost of use is only 1/4 of the cost of electric water heater. Compared to gas water heaters, it consumes no gas fuel and the cost of use is only 1/3 of the cost of gas water heaters. heat pump water heaters take air as the main body and save energy, which not only saves people's usage cost, but also corresponds to the main body of energy saving in the world. This is one of the biggest highlights of air energy water heaters.
Guangdong JNOD New Energy Technology Co., LTD. Focus on research and development of heat pumps and electric boilers, manufacturing and providing comprehensive energy saving solutions.
If you're thinking of getting a new air source heat pump, one of the things you will need to consider is what type of heat pump suits your property best, a monobloc or a split unit.
A monobloc air source heat pump comes in one single outdoor unit. This connects directly to the heating system of a property and can be controlled by an indoor control panel or thermostat. There is often also an outdoor control panel for the unit.
Benefits of a monobloc heat pump
There are several benefits to choosing a monobloc air source heat pump-which we have detailed below.
More indoor space
As monobloc air source heat pumps are single outdoor units, they are very effective at providing more space inside your property. Depending on what kind of boiler you had installed previously, you could gain some indoor space from where the boiler used to be.
Easier to install
Monobloc units are self-contained, meaning there is no need for the connection of refrigerant pipes. This means any trained heating engineer should be able to install one with little difficulty, as the only connections that need to be made are those of water pipes to the central heating system. Due to the simplicity of their installation, monobloc air source heat pumps can be installed quickly which, in turn, makes their installation less costly.
Easy to maintain
Due to their all-in-one design, monobloc heat pumps are easy to maintain. While this is more of a benefit to heating engineers that will be doing the maintenance, it could also mean that having someone at your property to run maintenance on your heat pump will take less time out of your day.
When choosing the best heat pump for your property, it is important to consider the disadvantages of each unit too. You can find the disadvantages of installing a monobloc heat pump below.
Whilst you can have a monobloc air source heat pump connected directly to your central heating system, to heat the water in your radiators or underfloor heating, you will not get any hot running water without the installation of a separate hot water storage tank. If you already have a regular boiler or system boiler installed at your property, this will only mean replacing the existing hot water tank. However, if you have a combi boiler, a new hot water storage tank will likely take up space in your property that was previously free.
Monobloc air source heat pumps have to be connected directly to the central heating system in a property. This means they will need to be located on an outer wall of your property with very little flexibility regarding whereabouts they can be installed.
A big drawback of monobloc air source heat pumps is their size. Due to them being an all-in-one unit, there is a lot of technology to fit in a single box. This makes them very large. If you have a small garden or your home has little or no front garden, you are going to struggle to find enough space to install a monobloc unit. Even if you do have enough space at the back of your property, the unit still needs a reasonably clear area around it to allow it to work at peak efficiency.
Split air source heat pumps consist of an outdoor fan unit and an indoor hydro unit. While the outdoor fan unit extracts ambient air from outside the property, the indoor unit heats the refrigerant and transfers its heat to the water in the central heating system. It also acts as a thermostat and control panel.
When choosing a split air source heat pump over a monobloc heat pump, there are several benefits which we have detailed below.
The outdoor units of split air source heat pumps are considerably smaller than their monobloc counterparts and will take up far less space outside of your property. Due to their smaller size, they are generally quieter to run as well.
Depending on the split air source heat pump you choose, you may not need a separate hot water storage tank to allow for hot running water in your home. This is because several indoor unit options include an integrated hot water storage tank in their design. These units can completely negate the need for a separate hot water storage tank, or reduce the size of a separate hot water storage tank you will need, depending on the unit you choose.
As the indoor unit of a split heat pump is the only part that's connected to the central heating system, this gives you more freedom with where you can place the outdoor unit. Some split air source heat pumps allow for the outdoor unit to be placed up to 75m away from the indoor unit. This gives you the potential to place the outdoor unit at the bottom of the garden out of the way, or up on a less intrusive wall.
When choosing the best heat pump for your property, it is important to consider the disadvantages of each unit too. You can find the disadvantages of installing a split heat pump below.
Due to the separate indoor and outdoor units, split heat pumps are more complicated to install. Many of them require the installation of refrigerant connections (which can only be done by a heating engineer with F gas qualifications). This makes the installation more time-consuming and is likely to increase the cost. As these units are also relatively new, you may find it harder to find a qualified heating engineer in your area as well.
Unsurprisingly, installing a split air source heat pump will probably take up more room inside your property than a monobloc heat pump. Mainly due to their being an indoor unit as well as an outdoor unit. The most drastic loss of indoor space you could face with a split heat pump is installing an indoor unit and a separate hot water storage tank. This would not only fill the space your boiler previously inhabited, but take up further space with a hot water storage tank. This can be remedied by opting for an indoor unit with an integrated hot water storage tank, but it is not something that should be overlooked.
Being more complicated in design than a monobloc heat pump, split air source heat pumps are generally a little more expensive to buy. Couple this with a potentially more costly installation and the price difference can start to add up. However, there is no guarantee a split heat pump will cost more than a monobloc, and you should always get comparison quotes to ensure you get the best installation price possible.
Unfortunately, when it comes to picking the best air source heat pump, there is no a definitive answer. All you can do is use the information we have provided and compare it against your circumstances. The best air source heat pump for you will be whichever best suits your home and your needs.
Whenever making a decision as big as this, we highly recommend getting advice from a local heating expert. Luckily, this is something we can help with.
