Do Heat Pumps Need Annual Maintenance​?

‌ Heat pumps require annual maintenance ‌. In general, the heat pump needs to be maintained 1 to 2 times a year to ensure its stable and efficient operation. Common heat pump maintenance includes the following aspects:

‌1. compressor check: the compressor is the core component of the heat pump, regularly check whether the suction and exhaust pressure, high and low pressure protection function is normal, through the sound to judge whether the normal operation ‌

2. heat exchanger cleaning: every 2 years, use about 55℃, 15% concentration of oxalic acid solution to clean the heat exchanger to ensure its heat exchange efficiency ‌

3. Refrigerant and piping check of the unit: check whether the pressure of the liquid storage tank is normal, ensure that the pipe joints and inflation valves of the unit are free of oil, and prevent refrigerant leakage ‌

4. Filter check: detect the temperature difference between incoming and outgoing water. If the temperature difference is greater than 5℃, it may be caused by the blockage of Y-type filter, resulting in small water flow and insufficient heat exchange. It is necessary to clean the filter ‌

5. Pump check: by listening and touching the way to judge whether the pump has abnormal sound or overload ‌

6. electronic control system: check whether the coil of the electric control cabinet is hot and the switch is damaged. Ensure that the power supply voltage is stable ‌

7. Other components: check whether the water supply, water tank safety valve, level controller, and exhaust device of the system work normally, and whether the water pipes and connectors leak ‌

In addition, the maintenance of the heat pump also includes regularly cleaning the dust on the surface of the heat exchanger, checking whether the waterway filter is blocked, checking whether the switch of the main electric control cabinet and the electric control cabinet is working normally ‌

Through these maintenance measures, the hidden dangers of the unit can be eliminated in advance to ensure its stable and efficient operation.
