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!

Swimming Pool Heat Pump is equipped with high-quality brand scroll compressors, with stable operation, low vibration, low noise, and low failure rate; key components such as thermal expansion valves, electronic appliances, etc. are well-known brand components with reliable performance.
How to choose a truly eco-friendly Swimming Pool Heat Pump?
What is the function of the Swimming Pool Heat Pump damping system?
Why choose an energy-efficient Swimming Pool Heat Pump?
The initial heating determines the model selection. The real energy saving stage of the Swimming Pool Heat Pump depends on the "constant temperature" period.
Select frequency conversion, more energy saving, the key to Swimming Pool Heat Pump lies in the operation logic of frequency conversion technology. In the constant temperature stage, the frequency conversion technology can enable the equipment to operate intelligently at a low frequency and match the real-time heating demand. There is no need to continuously heat the pool water by repeatedly starting and stopping like a fixed-frequency heat pump, so as to achieve the purpose of energy saving. We can compare the energy saving performance of fixed frequency heat pump and variable frequency heat pump under the same conditions.
Due to the difference in temperature, the heating efficiency of the heat pump will also be different. To compare the energy-saving effect in the constant temperature stage, we chose a fixed-frequency heat pump with the same heating level as the variable-frequency heat pump (IPHC150T) selected in the previous step at an air temperature of 26 °C (26 °C is generally used as the test temperature in the laboratory). Frequency selection is 60kw.
① The independent suspension shock absorption system makes the fan and motor run more quietly and reduces the noise caused by air disturbance.
② An integral base carries the fan and the motor, and according to the load-bearing distribution of each part, different types and quantities of shock absorbers are correspondingly configured to avoid jumping, anti-vibration and resonance, and make the operation of the fan and the motor more stable.
③ The fan and the box are isolated by flexible connection to avoid vibration transmission.
Considering indoor air quality, Swimming Pool Heat Pump is equipped with fresh air treatment function and exhaust function.
Considering the operating cost of the constant temperature heat removal pump unit, the Swimming Pool Heat Pump can use a large amount of outdoor low-humidity fresh air to adjust the humidity of the indoor air in spring and autumn, reducing operating costs.
In order to prevent the circulating air from affecting the service life of the Swimming Pool Heat Pump, the key components and sheet metal structure of the equipment are treated with anti-corrosion during the manufacturing process, and the compressor, power distribution cabinet and control system are isolated from the wind system.

A heat pump is part of a heating and cooling system. Like an air conditioner, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.
HOW A HEAT PUMP WORKS
A.COOLING MODE
One of the most important things to understand about heat pump operation and the process of transferring heat is that heat energy naturally wants to move to areas with lower temperatures and less pressure. Heat pumps rely on this physical property, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. This is how a heat pump works.
B.HEATING MODE
A Heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed by the aptly named reversing valve. The flow reversal means that the heating source becomes the outside air (even when outdoor temperatures are low) and the heat energy is released inside the home. The outside coil now has the function of an evaporator, and the indoor coil now has the role of the condenser.
The physics of the process are the same. Heat energy is absorbed in the outdoor unit by cool liquid refrigerant, turning it into cold gas. Pressure is then applied to the cold gas, turning it to hot gas. The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle.
Now, more and more families are making the preparation for the Winter, Like installing the heat pump for house heating and hot water.
No hesitate to contact us for OEM/ODM cooperation and development.
The heating and cooling heat pump is a highly efficient, energy-saving device that makes full use of inferior thermal energy. Heat can be transferred spontaneously from a hot object to a cold object, but not spontaneously in the opposite direction.
How does the heating and cooling heat pump work?
What does the operating time of the heating and cooling heat pump have to do?
What is the function of the heating and cooling heat pump?
In the heating and cooling circuit of the heat pump, the heat Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed, while the heat of Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed. The heating system) provides the heat of Q1kcal/h, and the relationship between these heats corresponds to the first main law of thermodynamics, ie Q1=Q0+ALkcal/h
If the heating and cooling heat pump is not used and the heat is converted by mechanical work (or the high temperature heat source is heated directly by electrical energy, the heat obtained is ALkcal/h, and after the heat pump device is used, the high temperature heat source (heating system) receives more heat is obtained: Q1-AL=Q0, kcal/h This heat is obtained from a low temperature heat source, and this heat cannot be obtained without a heat pump device. Therefore, using a heat pump device can save fuel and use waste heat.
The working cycle of a heating and cooling heat pump is exactly the opposite of that of a thermal engine. A thermal engine uses the energy of a high-temperature heat source to generate mechanical work, while a heat pump transfers heat from a low-temperature heat source to a high-temperature object by consuming mechanical work.
If the heat pump and the heat engine have two identical heat source temperatures, the thermal efficiency of the heat engine cycle is η=AL/Q1; the energy index of the thermal engine cycle – the heat conversion coefficient φ=Q1/AL, i.e. φ=1/η. The value of η is always less than 1, so the value of φ is greater than 1.
If the refrigerator and the heat pump have two identical heat source temperatures, the relationship between them is φ=Q1/AL=(Q0+AL)/AL=e+1, where η is the refrigerator's cooling coefficient. It can be seen that the minimum value of the heat transfer coefficient φ η1 and in this limit case Q0 E0, that is, no heat is absorbed from the low temperature heat source.
