How to improve the efficiency of air energy heat pump and extend its service life? You must have such a question. Now let's follow up with our small staff of Nakstar to understand that the operation performance and service life of the irregular and effective maintenance unit will be greatly improved!

1. When the temperature is lower than 2 ℃, if the unit is stopped or power is cut off, the water in the unit pipeline must be drained in time, the power supply must be cut off, and protective measures must be taken. During re operation, the system shall be comprehensively checked and confirmed before startup.

2. The water filter installed in the unit shall be cleaned regularly according to the local water quality (preferably once a quarter) to ensure that the water quality in the system is clean and the water circulation is smooth, so as to avoid affecting the efficiency of hot water production or accidental damage due to dirty water or filter blockage and reduced water circulation.

3. Check whether the wiring of the electrical system of the unit is firm and whether the electrical components are abnormal. If any, please handle it in time.

4. Regularly check whether the water make-up, liquid level controller and exhaust device of the water system work normally, so as to avoid excessive overflow and reduction of water circulation, which will affect the heat generation of the unit and the reliability of unit operation.

5. Please keep dry operation and good ventilation around the unit. Clean the air side heat exchanger regularly (preferably once a quarter) to maintain good heat exchange effect. Do not stack sundries around the unit to avoid blocking the air inlet and outlet. Keep the unit clean and dry with good ventilation.

6. Frequently check the working condition of each component of the unit, check whether there is oil stain at the unit pipe joints and air charging valves, and ensure that there is no leakage in the refrigeration of the unit. Pay attention to check whether the water pump and waterway valve work normally, and whether there is leakage in the water pipeline and water pipe joints.

7. The scale of the water tank shall be removed after being used for a period of time (depending on the local water quality).
