Heating and Cooling Heat Pump installs a four-way reversing valve on the basis of ordinary air conditioners, and changes the operation of the valve, which can exchange the functions of the evaporator and the condenser of the original air conditioner, so as to change the function of cooling indoor air. Changed to the function of heating indoor air.
What are the structural advantages of the Heating and Cooling Heat Pump?
What is the user's experience with Heating and Cooling Heat Pump?
Why the use of Heating and Cooling Heat Pump can save resources?
The evaporator of the Heating and Cooling Heat Pump adopts the method of countercurrent heat exchange for heat exchange to enhance the heat exchange effect; moreover, the heat exchange method combining fins and tube bundles is used, and each row of heat exchange tubes is arranged in a cross. The method of turbulence increases the convective heat transfer coefficient on the exhaust side and enhances the heat transfer effect;
The refrigerant tube bundle of Heating and Cooling Heat Pump is made of red copper, and the fins are made of hydrophilic aluminum foil. The condensed water in the exhausted air drips on the surface of the heat exchanger to form a water film that is conducive to heat exchange, increasing the heat exchange coefficient and enhancing the heat exchange effect;
The Heating and Cooling Heat Pump has an advanced microcomputer control system, and adopts a special programmable controller PLC for imported air-conditioning equipment, which has the ability to resist electromagnetic interference, intelligent coupling between building load and unit heating; Display, fault alarm and diagnosis functions.
The Heating and Cooling Heat Pumpis also very comfortable, clean and safe. In the past, when burning coal, it was not only dirty, tiring and troublesome, but also the temperature was not high, usually 14-16 degrees, and you had to wear cotton-padded clothes at home. Now open to 18 degrees and wear a thin sweater. If the weather is cold, turn up the temperature. Anyway, the Heating and Cooling Heat Pump is also very convenient, and you can adjust the temperature by pressing a button.
The Heating and Cooling Heat Pump unit has the dual functions of supplying cold water in summer and supplying hot water in winter. Using air as the heat source and cooling source can greatly save water and avoid the pollution of water quality. The air-cooled modular cold and hot water unit can be placed on the top floor of the building or on the outdoor platform to work, eliminating the need for a dedicated cold source machine room and boiler room.

The Heating and Cooling Heat Pump is driven by an electric motor, uses the heat in the air as a low-temperature heat source, exchanges heat through the air conditioner condenser or evaporator, and then passes through the circulation system to extract or release heat energy, and use the unit circulation system to transfer the energy to the building. It can meet the needs of users for domestic hot water, floor heating or air conditioning.
What is the cycle between the Heating and Cooling Heat Pump and the natural environment?
What is the principle of Heating and Cooling Heat Pump?
Does the Heating and Cooling Heat Pump make noise?
The compressor outlet of the Heating and Cooling Heat Pump is high-temperature and high-pressure gas, which is transformed into a high-pressure and low-temperature vapor-liquid mixture through the heat exchange of the condenser. The low-temperature gas enters the evaporator to evaporate and absorb heat, and absorb the low-grade heat energy from the outside world (which can be rivers, lakes, groundwater, underground soil layers, air, etc., which we call water source, ground source, and air source heat pump), and finally the evaporator comes out. The low pressure gas enters the compressor to complete the cycle.
Heating and Cooling Heat Pump is an evolved product of air conditioners. An electromagnetic four-way valve (also known as a reversing valve) is installed in the refrigeration system. Through the switching direction of the four-way valve, the flow direction of the refrigerant is changed, and the air conditioner can hot. The high-temperature and high-pressure vapor-like refrigerant discharged from the compressor flows to the condenser in the heat preservation water tank, transfers heat to the tap water passing through the water tank, and then throttles and reduces the pressure through the expansion valve, and evaporates and absorbs heat in the evaporator of the main outdoor heat pump group. Use the working fluid to absorb the heat in the outdoor air. The Heating and Cooling Heat Pump absorbs the heat in the outdoor air and transfers it to the tap water in the insulated water tank. It is more energy-saving, fast and safe than simply heating with an electric heater, and the outdoor thermal energy potential is infinite.
Noise problem, almost all of today's Heating and Cooling Heat Pumps use full frequency conversion technology, indoor unit frequency conversion, heat pump host frequency conversion, fan frequency conversion, etc. The noise value of the heat pump host is below 45 decibels, and the indoor noise is still below 20 decibels. Neither users nor neighbors will be affected.

The heat pump water heater uses a heat pump to absorb the air heat source to produce hot water. The energy saving efficiency is more than 3 times that of the electric water heater. It is more energy efficient than the solar water heater.
What is a direct heat pump water heater?
What are the characteristics of direct heat pump water heaters?
What is the main structure of the direct heat pump water heater?
The direct heat pump water heater is also known as the fast or fast heat pump water heater. The basic characteristics of the direct heat pump water heater are: cold water and superheated water, as long as the tap is turned on, the energy source will continuously supply hot water within a few seconds. Turn off the faucet when you don't need hot water.
According to different heating forms, direct heat pump electric water heaters can be divided into the following three types:
①, bare electric wire heating electric water heater;
②, electric film heating electric water heater;
③, electric heating tube heating electric water heater.
The heater of the direct heat pump water heateris set in a tank frame, which cannot withstand too high water pressure. At the same time, the left and right poles of the tank frame and the two poles introduced by the heating wire will be affected by water pressure for a long time. be damaged. Therefore, direct heating heat pump water heaters cannot be made into the post-system, but are all made into the front-system. In addition, in order to ensure the safe use of direct-heat heat pump water heaters and no dry burning occurs, a pressure sensing activation switch with water flow as a signal is installed at the cold water inlet, and the pressure sensing activation switch diaphragm can withstand the pressure. It is limited and cannot withstand pressure for a long time, so direct heat pump water heaters are generally made into the former system.
A typical direct heat pump water heater is mainly composed of a heating tank plate, a pressure sensor, a power regulator, a water volume adjustment faucet, a water inlet pipe and a water outlet pipe component, among which the heating tank plate is the key component of the direct heat pump water heater. It consists of a groove weight, a sealing ring, a cover and an electric heating element, and the electric heating element is located in the groove of the groove plate.
The direct heat pump water heater works by direct conduction heating. Since the electric heating element is placed in the groove of the groove plate, when the cold water flows through the groove, it can directly flow through the surface of the heating element to be heated. And because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and hot water with a higher temperature can be obtained at the water outlet.
Guangdong JNOD New Energy Technology Co., LTD. can produce standard products under clients' brand, modify the products to satisfy client's personalized requirements and work together with clients to design and produce totally new products.
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.
JNOD has a complete heat pump industry chain, and its products involves Swimming Pool Heat Pump, House Heating & Cooling Heat Pump, Domestic Hot Water Heat Pump, Heat Pump Dehumidifier, Commercial & Industrial High Temperature Water Heating Solution, Industrial and Agricultural Heat Pump Dryer,etc.The ultra-low temperature EVI heat pump has been widely used, too.
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.
Air source heat pump water heaters are the same as the heating principle of air conditioners, they are all heat carriers. The air conditioner moves the outdoor heat into the room, and the air energy water heater moves the outdoor heat to the water tank to heat the cold water in the water tank. Because the heat in the air is free, the air energy water heater also saves electricity.
What is the operating mode and principle of the unit composition of the heat pump water heater?
What are the benefits of installing a heat pump water heater?
What is the difference between a heat pump water heater and an air conditioner?
The heat pump hot water unit is composed of a refrigeration cycle, including two parts: the main engine and the condenser. The main engine part includes evaporator, fan, compressor and expansion valve; the condenser is an incubator with condensing coils inside. The refrigerant absorbs the heat from the outside air in the evaporator and releases heat in the condensing coil through the heat pump cycle to heat the water in the water tank. The thermal insulation layer of the water tank is foamed with closed-cell rubber sponge or polyurethane, and has good thermal insulation performance.
1. Safety: No gas, no waste gas, and no "gas poisoning"; no electric heating rod for heating, there is no danger of leakage, and people's health and safety are protected.
2. Save money: The COP value is more than 3, the energy efficiency ratio is high, and it definitely saves electricity and money. It can save 2/3~3/4 of electricity expenses, or 1/2~2/3 of gas expenses and auxiliary heating expenses of solar water heaters.
3. Comfort: automatic constant temperature and pressure water supply, never hot and cold when using hot water, hot water has pressure, good comfort. All-weather supply of domestic hot water makes up for the embarrassment of solar energy when there is no hot water available in rainy days, nights, no sunlight, and freezing.
4. Environmental protection: The cold air discharged from the heat pump water heater is beneficial to reduce the room temperature.
Comparison of heat pump water heaters and air conditioners: The principle of heat pump water heaters and air conditioners is the same, but the technical content of heat pump water heaters is higher than that of air conditioners, which is why heat pump water heaters have only been listed in recent years. In general, heat pump water heaters are the product of the development of science and technology to a certain stage. The heat dissipation temperature of the air conditioner cannot work in an environment where the cooling temperature is 40~50°C, and the water temperature of the heat pump water heater can reach about 60°C or even higher.
Guangdong JNOD New Energy Technology Co., LTD., which has been established for several years, focuses on the production of heat pump water heaters. Here, you can find the heat pump water heaters you need.
