300 Liters Compact Air-Source Heat Pump Water Heater with En255-3

Compact Air Source Heat Pump Water Heater
-------FREE-CP-300L

Working principle:

Air source heat pumps are relatively easy (and inexpensive) to install and have therefore historicall Been the most widely used heat pump type. However, they suffer limitations due to their use of the Outside air as a heat source or sink. The higher temperature differential during periods of extreme Cold or heat leads to declining efficiency, as explained above. In mild weather, COP may be around 4.0, while at temperatures below around? 8 ° C (17 ° F) an air-source heat pump can achieve a COP of 2.5 or better, which is considerably more than the COP that may be achieved by conventional heating systems. The average COP over seasonal variation is typically 2.5-2.8, [9] with exceptional models able to exceed 6.0 (2.8 kW).

The working fluid, in its gaseous state, is pressurized and circulated through the system by a Compressor. On the discharge side of the compressor, the now hot and highly pressurized gas is Cooled in a heat exchanger, called a condenser, until it condenses into a high pressure, moderate Temperature liquid. The condensed refrigerant then passes through a pressure-lowering device like an expansion valve, capillary tube, or possibly a work-extracting device such as a turbine. This device then passes the low pressure, (almost) liquid refrigerant to another heat exchanger, the evaporator where the refrigerant evaporates into a gas via heat absorption. The refrigerant then returns to the compressor and The cycle is repeated.



Features of Air Source Heat Pump Water Heater

1. High-efficiency and energy saving:
The power consumption of air-source heat pump is as low as 1/4 of electric heating. A considerable cost could be cut off with for user.

2. Safty and reliability:
The water is heated by through the refrigerating medium, which completely aviods hazards of explosion, gas poisoning, electroshock, etc.

3. Intelligent controller: With a high-tech and intelligent controller, it is easy to operate/set the founction, from switching on/off time to water temperature.

4. Installing and Operating easily: It is easy to instal the unit on balcony, basement or anywhere indoors /outdoors.
Reliability: Absorbing energy from air, even in rainy dasys, the unit can work and supplier hot water 24 hours.

5. Inner tank: The innder tank is made of 304-2B stainless steel, which maintains water clean.

6. Working condition: It runs well with the temperature range from -7C to 43C.

7. Multi-function: As the unit heating hot water, it can dehumidicate the space and recycle the waste thermal energy.

8. Waste Heat Recovery: There is an auxiliary exchanging coil, which can be installed with gas boiler, solar panels and other thermal device/unit.

9. Enviornment-friendly: The refrigerator is R417 that match the international standard on enviornment protection. In the process of heating, there is no wast substance released. The unit provides users a clean and comfortable living enviornment.
