Working Principle:

● The internal structure of water circulation air source heat pump water heater is mainly composed of

four core components: split pressurized water tank, compressor, expansion valve and evaporator.

 ● Under the action of fans, a large amount of air flows through the outside surface of evaporator, and

the energy in air is absorbed by evaporator, and the refrigerant which absorb scertain energy is returned

to the compressor.

● Compressor compresses the low-pressure refrigerant which returns to flow, and then discharges the high

temperature and high pressure gas. The high temperature and high pressurere frigerant gas flows through the

coiler heat exchanger in the water tank, and the heat is transmitted to the water tank through the coiler heat

exchange in the split pressurized water tank inside.

 ● Internally, the cooled refrigerant becomes liquid under the continuous action of pressure and enters the

evaporator after the expansion valve. As the pressure of the evaporator drops sharply, the liquid refrigerant

evaporates rapidly into the gaseous state here and absorbs a large amount of heat and enters the next cycle.

 ● The working principle of air source heat pump water heater is similar to that of air-conditioner. Inverse Carnot

principle is applied to heat water by absorbing a large amount of low-temperature heat energy in air and transforming

it into high-temperature heat energy through compressor compression.

Salient Characteristic：

【1】High efficiency and most energy-saving water heater.

The air source heat pump water heater is a revolutionary new generation of water heater. Using 1KW electric energy

can produce heat energy equivalent to 4KW electric energy. Its energy saving effect is four times as much as that of

electric water heater, three times as much as that of gas water heater and about two times as much as that of solar

water heater.

 【2】Better Environmental adaptability.

Because the amount of air is not affected by indoor and outdoor, sunny and cloudy days, compared with solar water

heater, air source heat pump water heater is very convenient, temperature -7 to 43 degrees Celsius, both can be

used.

 【3】Provide high water pressure and constant temperature hot water.

Whole system can operate under high pressure, In addition, after using up a tank of water, it can produce another tank

of hot water in less than an hour, which can provide different hot water needs of the whole family 24 hours a day with

large water volume, high water pressure and constant temperature.

 【4】Safety & reliability.

Compared with the electric water heater and gas water heater, the air source heat pump water heater exchanges heat

through medium, avoids the direct contact between electric heating elements and water, thus resolving the potential

leakage of electricity in the electric water heater. Secondly, because the raw material is air, Therefore, it also excludes

the possibility of gas explosion or gas poisoning in gas water heater, so that people can use it more comfortably and

carefree.

 【5】Environmental protection.

The air source heat pump water heater uses electric energy to compress air to produce heat energy, and does not

emit exhaust gas and toxic gas. It is not only safe, but also creates a non-polluting bathing environment.

 【6】Long life performance.

The production cost of the air source heat pump water heater is high, but the life span can be 15-20 years.
