We are one of the professional air source heat pump suppliers based in China. Our main air source heat pump system series include household mini heat pump, dc inverter heat pump, high temperature heat pump, evi low temperature heat pump, swimming pool heat pump, heat pump dryer, heating and cooling heat pump, geothermal heat pump (floor heating) and so on. All heat pumps are in high quality and good performance. Click the following to view more details:

Air Source Heat Pump Performance

Air Source Heat Pump Performance When comparing the performance of heat pumps, it is best to avoid the word "efficiency", which has a very specific thermodynamic definition. The term coefficient of performance (COP) is used to describe the ratio of useful heat movement per work input. Most vapor-compression heat pumps use electrically powered motors for their work input.

Air Source Heat Pump Maintenance

1) The unit status should be examined regularly due to the air source heat pump water heater is highly automated. If a long-term and effective maintenance can be carried out, the operational reliability and service life will be increased incredibly.

2) The connection between power supply and electrical system of the unit of air source heat pump water heater as well as the working order of electrical components should be checked up so that they can be repaired and replaced if necessary.

3) The filter of waterways installed outside the machine ought to be cleaned termly in order to make sure the cleanness of water quality within the system, avoiding the damage of main engine because of the blocking and dinginess of units.

4) No sundries are around the units in case that the inlet and outlet are stopped up; instead, the surroundings of units should keep clean and well-ventilated.

5) Matters should be paid attention to when users apply and maintain the units of air source heat pump water heater: all safety protection devices of the units should be set already before leaving the factory, prohibiting from being dissembled or adjusted on their own.

6) It is better to have regular check that whether water replenishing of the system, safety valve of water tank, level controller and air escape work so that no air will enter into the system to reduce the water circulation, which can not influence heating capacity and operational reliability of the units.

7) To detect the service conditions of all parts of the units and the degree of grease dirt in the line joints and inflation tab inside the machine can ensure that there is no leakage of refrigerant in the units.

8) To be clean, dry and well-ventilated around the units is a must. A good cooling capacity comes from annual cleaning for airside heat exchanger.

9) The water pump and valves for water circuits operating normally and water pipeline and water pipe head free from leakage should be guaranteed.

10) Condenser of main engine is suggested to be cleaned every two years with hot phosphoric acid solution of 15% concentrations at 50℃-60℃. Next, the circulating water pump of main engine is ready for washing for three hours. And finally, tap-water is used to wash for three times for sake of water pipe connecting. It is banned to use corrosive cleaning solution.

11) The water in the pipes of the units should be discharged, current source cut off and protective cover put on owing to the long downtime. When it restarts, a complete previous check should proceed.

12) When leaving water temp of air source heat pump water heater is different from value displayed on the control panel of the units, you should get to know if the contacts of thermometer devices are good.

13) The Incrustant ought to get out of the water tank ( it is generally apply water to clean it after using for three months, but all is based on local water quality.)

14) When the units break down while the uses have no idea on it, please contact the after-sales personnel in time and inform them of fault code, which will fasten the repairing.

Air Source Heat Pump Installation

  1. First of all, to determine the location of the unit, mainly considering the floor load, the impact of the unit's inlet and outlet air.

  2. For foundation fabrication, cement or channel steel can be used, and the foundation must be on the load-bearing beam of the floor.

  3. Put the adjustment to ensure that the unit is placed smoothly, and the damping rubber pad is adopted between the unit and the foundation.

  4. The connection of the waterway system is mainly the connection of water pumps, valves and filters between the main engine and the water tank.

  5. Electrical connection, main engine power line, pump, solenoid valve, water temperature sensor, pressure switch, target flow switch, etc. according to the wiring diagram requirements for electrical connection.

  6. Water pressure test, check whether there is water leakage in pipeline connection.

  7. The machine must be grounded before starting up. Megohm meter is used to check the insulation performance of the machine. Check no problem, boot up. A universal meter is used to check the running current and voltage of the machine.

  8. Pipeline insulation, using rubber and plastic insulation materials for insulation, the external surface of aluminum sheet or thin galvanized steel plate for fixation.

Air Source Heat Pump Technology

Air Source Heat Pump Technology Heating and cooling is accomplished by pumping a refrigerant through the heat pump's indoor and outdoor coils. Like in a refrigerator,a compressor, condenser, expansion valve and evaporator are used to change states of the refrigerant between colder liquid and hotter gas states.

When the liquid refrigerant at a low temperature and low pressure passes through the outdoor heat exchanger coils, ambient heat causes the liquid to boil (change to gas or vapor): heat energy from the outside air has been absorbed and stored in the refrigerant as latent heat. The gas is then compressed using an electric pump; the compression increases the temperature of the gas.

Inside the building, the gas passes through a pressure valve into heat exchanger coils. There, the hot refrigerant gas condenses back to a liquid and transfers the stored latent heat to the indoor air, water heating or hot water system. The indoor air or heating water is pumped across the heat exchanger by an electric pump or fan.

The cool liquid refrigerant then re-enter the outdoor heat exchanger coils to begin a new cycle. Most heat pumps/air source heat pump air conditioning can also operate in a cooling mode where the cold refrigerant is moved through the indoor coils to cool the room air.
