Heating and Cooling Heat Pump uses scientific methods to make low-temperature heat energy flow to high-temperature heat energy according to the "inverse Carnot principle", and obtains more heat energy from the air, which has wide adaptability.
How does the Heating and Cooling Heat Pump cycle for cooling and heating?
What is the principle of Heating and Cooling Heat Pump?
Can the Heating and Cooling Heat Pump still operate at an ambient temperature of 0°C?
During heating, the refrigerant (environmentally friendly refrigerant) in the Heating and Cooling Heat Pump host will absorb the low-temperature heat energy in the air through the evaporator, and then convert it into high-temperature heat energy through the compressor, and then transfer the heat energy to the heating circulating water through the heat exchanger. Finally, the heated hot water is transported to the indoor heating terminal for heat dissipation through the water pump, and then returned to the heat exchanger for heating after the heat dissipation, and the process is repeated.
During cooling, the cycle of the Heating and Cooling Heat Pump system is just the opposite, absorbing the indoor heat and transferring it to the outdoors. Air heat exchange, an additional heat exchange program.
Shallow water sources on the earth's surface (generally within 1000 meters), such as groundwater, surface rivers, lakes and oceans, absorb considerable radiant energy from the sun into the earth, and the temperature of water sources is generally very stable. The working principle of Heating and Cooling Heat Pump is to realize the transfer of low-temperature heat to high-temperature by inputting a small amount of high-grade energy (such as electric energy). The water body is used as the heat source of heat pump heating in winter and the cold source of air conditioning in summer, that is, the heat in the building is "taken out" and released into the water body in summer. Because the water source temperature is low, it can efficiently take away the heat, so as to achieve the purpose of indoor cooling of the building in summer; In winter, heat energy is "extracted" from the water source and sent to the building for heating through Heating and Cooling Heat Pump.
The answer is yes, although Heating and Cooling Heat Pumpproducts were mostly used in high temperature areas in the early days, with the continuous development of heat pump technology, air energy heat pump heating can be used in most areas, especially for some low temperature environments. The Heating and Cooling Heat Pump uses technologies such as jet enthalpy to ensure that the Heating and Cooling Heat Pump can operate normally in severe cold climates.

More and more people choose heat pump water heatersbecause air energy is the most energy-efficient, that is, the lowest operating cost, compared to most water heaters that consume electricity and gas.
How does the heat pump water heater achieve the effect of saving energy?
What should we pay attention to when using heat pump water heater?
What are the operational advantages of heat pump water heaters?
When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.
temperature, water consumption
Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.
How much hot water can be made
In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.
The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.
The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.
Guangdong JNOD New Energy Technology Co., LTD. has focused on the field of heat pump water heaters for many years, it commits to providing perfect service for every customer in the world.
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.
Air source heat pumps are a relatively new technology that can be used to heat your property in a more environmentally friendly and energy efficient way. As they use the ambient air outside of the property as their heat source, there is no need for a gas supply. This makes them a suitable heating solution for most homes, regardless of whether they are connected to the gas network.
There are 2 types of air source heat pump: air to water and air to air. This is how each of them works.
How an air to water heat pump works
Here is a step by step breakdown of how an air to water heat pump works:
1. The heat pump has an outdoor unit, which contains a fan that draws air in from outside the property. This air then passes over tubes or coils filled with liquid refrigerant.
2. The liquid refrigerant is much colder than the ambient temperature, even if the outside air is at sub-zero temperatures, and begins to heat up when air is passed over it.
3. As the refrigerant continues to heat up, it becomes steam which is moved to a compressor. This compresses the steam which raises the temperature of the refrigerant even further.
4. The heat of the refrigerant is then transferred to the water in the central heating system in your home, and any water stored in a hot water tank, for hot running water.
5. The refrigerant, which has now passed on its heat, is then cooled and cycled back to begin the process again.
How an air to water heat pump works
Air to air heat pumps are essentially updated versions of air conditioning units that don't only cool air, but can also heat it. They work in the same way as an air to water heat pump, but transfer heat to the air in a ventilation system, rather than to the water in a central heating system.
A big drawback of air to air heat pumps is that they require a property to have air ducts installed throughout, in which to distribute warm air. They are also incapable of heating running water. This means they are not generally suitable for existing and older properties.
We have provided an in depth comparison of these heat pumps in our Air to Water Heat Pumps vs Air to Air Heat Pumps article.
Not only are there air to water and air to air heat pumps, but each of these types of air source heat pump is generally available in different models. Namely monobloc air source heat pumps and split air source heat pumps.
Monobloc heat pumps
These are a large single outdoor fan unit which connects directly to the central heating system and will need to be located close to your property. There is no indoor unit, which can help to free-up space inside your property.
Split heat pumps
Split heat pumps consist of 2 main units: the outdoor fan unit and the indoor heating and cooling unit. These generally take up less space outside, but will require the use of some inside space.
To understand the pros and cons of monobloc and split air source heat pumps, and to find out more about how they differ, you can go to our article: Split Heat Pumps vs Monobloc Heat Pumps
Air to water heat pumps often come in 2 separate temperature ranges: low temperature and high temperature. It's important to know what each of these temperature types are as they could affect your installation costs.
Low temperature heat pumps
While traditional gas boilers will heat the water in a central heating system to temperatures of around 80°C to ensure the radiators around the property are providing ample heat. Low temperature air source heat pumps are only capable of heating radiators to a temperature of around 60°C. Due to the lower maximum temperature these heat pumps are capable of producing, more heated surface area is required to keep a property warm. This means you will need bigger radiators or underfloor heating to truly benefit from the installation of a low temperature heat pump.
High temperature heat pumps
Generally, high temperature air source heat pumps are capable of heating the water in a central heating system to around 75°C – 80°C. This is more in line with the temperatures provided by gas boilers. This makes them easier to integrate into an existing traditional heating system, but they do require more power to run.
For an in depth comparison and explanation of different temperature levels in heat pumps, check out our Low Temperature vs High Temperature Air Source Heat Pumps article.
There are many benefits to getting an air source heat pump installed at your property, but there are some disadvantages too. To help you make the right decision for your home, we created the article: Air Source Heat Pumps vs Gas Boilers. This covers the advantages and disadvantages of each technology, cost comparisons and things you will need to consider when getting either heating solution installed.
As air source heat pumps are a relatively new technology, you may find it harder to find a heating engineer in your area that's well versed with installing them. More and more heating engineers are starting to adopt air source heat pumps as a heating solution they will install, but it may not be clear where to find them.
Fortunately, this is something we can help with. Simply click the link below and we'll find you up to 3 quotes from air source trained heating engineers in your area.
Swimming Pool heat pumps are one of the most cost efficient heating options on the market.

Swimming Pool Heat Pump Benefits
Reliable and durable heat pumps require fewer repairs than gas heaters.
No emissions and low electrical use make heat pumps the eco-friendly pool heater.
Heats for much lower costs, costing 50-75% less than gas heaters to operate.
How Swimming Pool Heat Pumps Work:Swimming Pool heat pumps leverage a combination of air and electricity to heat your pool water. They use electricity to power a fan and a small compressor, to absorb surrounding air heat and transfer it into your pool’s water. Pool heat pumps require very little electricity to run.
Swimming Pool Heat Pump Installation: Heat pumps can be purchased, placed level and plumbed after the filter by any handy homeowner, but we recommend an electrician to come in for the power hook-up.
Swimming Pool Heat Pump Operation Cost: The cost to operate a heat pump depends on many factors such as size of Swimming pool, size of heat pump and the outside air temperature. When the air temperatures are colder, the fan and compressor must run longer to maintain temperature, but during warmer periods the heat pump may need to run only an hour per day to maintain water temperature.
For the swimming pool heat pump, we have both R32 and R410A model. The heating capacity can be made from 3KW to 97.5KW. ON/OFF and inverter model,residetial and commercial are available. It’s with 4 ways valve,provide both heating and cooling mode to create more possibility for pool enjoyment.

With the continuous improvement of living standards, there are more and more users of heating and central air conditioning. Central heating users do not need to worry about the choice of equipment, while household heating users need to face a dazzling array of hot and cold equipment, which is difficult to carry out. choose. Heating and Cooling Heat Pumps are constantly entering the public's field of vision, and are sought after by many users because of their environmental protection and energy-saving features. But what else should you know before choosing a Heating and Cooling Heat Pump?

How to save resources when heating with Heating and Cooling Heat Pump?
The Heating and Cooling Heat Pumpcan adjust the indoor temperature by absorbing the heat energy in the air and then transferring it to the water for heat exchange. In summer, it is cooled by fan coil unit, and in winter, it is heated by fan coil unit, floor heating or radiator. It has a dual-purpose function. Heating and Cooling Heat Pump can also be connected in areas with better environment. Domestic hot water, and even the water heater are saved.
Heating and Cooling Heat Pumprefrigeration is to cool the circulating water in the pipeline into chilled water through the heat pump unit. The outlet air temperature of the indoor fan coil is between 15°C and 20°C. The chilled water is circulated into the room for heat exchange, and the evaporator The heat absorption in the room transfers the heat in the room to the circulating water in the pipeline, and then the circulating water after the heat absorption is brought to the heat exchanger configured by the heat pump unit through the operation of the water pump for heat exchange, and finally the heat pump host discharges the heat to the air In the cycle, this process is repeated to achieve the effect of indoor cooling. However, it should be noted that after the circulating water in the pipeline is cooled by the Heating and Cooling Heat Pump, the temperature can be kept stable for a long time without heat exchange, and there is no short-term loss of cooling capacity. Energy consumption will also be lower.
Heating and Cooling Heat Pump heating is to replace the collected heat into the heating pipeline through the heat pump unit, and then deliver the water to the floor heating, fan coil and radiator at 35°C-45°C, 40°C-50°C and 55°C respectively. The heat is released in the middle, so as to achieve the effect of indoor heating. Because the air energy heat pump adopts frequency conversion technology and jet enthalpy increasing technology, it has a high energy efficiency ratio, and can obtain more than three times the heat energy from the low temperature environment, and the energy saving performance will be much higher than that of direct conversion of electric energy into heat energy.

The heat pump water heater absorbs air energy through the compressor, releases heat through the refrigerant and then heats the hot water. In general, it is a purely electric or boiler fuel, and the air source is supposed to transfer the energy of the air to the water through a certain amount of electrical energy. It is cost effective and has low operating cost. That's the most important thing. heat pump water heaters are safer, more energy-saving, more environmentally friendly, safer and fashionable than ordinary water heaters.
What is the basic working principle of a heat pump water heater?
What are the advantages of heat pump water heater and solar water heater?
Heating and cooling heat pump can be connected to Wi-Fi?
Heat pump water heater mainly consists of compressor, heat exchanger, axial fan, water tank for heat preservation, 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.
Both work with air and solar energy, two of nature's renewable energy sources. What's the difference between the two?
In all seasons, even in winter, the effect of solar water heaters is very clear with sufficient sunlight, as well as on long rainy, snow and cloudy days. Solar water heaters cannot reflect the heating effect. The heat pump water heater is not affected by weather and season. It can supply hot water to users at any time. To be clear: The air flow heater can have hot water where there is air!
