Knowledge of maintenance of air energy heat pump
The air energy water heater is composed of an outdoor unit and an insulated water tank. The outdoor unit is called an air energy heat pump unit. The air energy heat pump unit is generally composed of compressors, expansion valves, evaporators, condensers and other main components. Simply put, the working principle of air energy water heaters is that the low-temperature refrigerant in the compressor system continuously absorbs the low-grade heat in the outdoor air and brings it back to the compressor to upgrade it to usable high-grade heat to heat the cold water. The heating principle of the air energy water heater is the same as that of the air conditioner, but the product configuration is different. The air energy water heater is mainly used for heating water, increasing the heat exchange area of the evaporator and condenser, and adopting high temperature resistance and high pressure resistance Compressor system.

1. The air source heat pump water heater often checks whether the power supply of the unit and the wiring of the electrical system are firm, whether the electrical components have abnormal movements, and if so, they should be repaired and replaced in time.

2. The water filter installed outside the machine should be cleaned regularly to ensure that the water quality in the system is clean, so as to avoid damage to the host due to the dirty filter of the unit.

3. Do not pile debris around the unit, so as not to block the air inlet and outlet, the unit should be kept clean and dry, and well ventilated.

4. The user should pay attention to when using and maintaining the air energy heat pump unit: all safety protection devices in the unit are set before leaving the factory. Do not disassemble or adjust them by yourself.

5. Regularly check whether the water supply system of the water system, the safety valve of the water tank, the liquid level controller and the exhaust device are working properly, so as to prevent the air from entering the system and reducing the water circulation, thus affecting the heating capacity of the unit and the reliability of the unit operation.

6. Frequently check the working conditions of each unit of the unit, check whether the pipeline joints and inflation valves in the machine are oily, and ensure that the unit refrigerant does not leak.

7. Keep clean and dry around the unit, and have good ventilation. The air-side heat exchanger is cleaned every year to maintain a good heat exchange effect.

8. Check whether the water pump and waterway valve are working properly, and whether the water pipeline and water pipe joint are leaking.

9. Condenser cleaning of the host, we recommend to use the descaling agent to clean the condenser every year, start the host to carry the circulating water pump to clean for 45 minutes, * wash with tap water 3 times. In case of taking over when cleaning. It is forbidden to use corrosive cleaning fluid to clean the condenser.

10. If the shutdown time is longer, the water in the pipeline of the unit should be drained, the power supply should be cut off, and the protective cover should be put on. When running again, conduct a full inspection of the system before turning it on.

11. When the actual outlet temperature of the air source heat pump water heater is inconsistent with the value displayed on the control panel of the unit, please check whether the temperature sensing device is in good contact.

12. The water tank needs to be cleaned after using it for a period of time (generally 3 months, depending on the local water quality).
