Many household appliances in the home require maintenance by users, and for household appliances, it is to prolong the service life of household appliances. As an air-conditioning system that has not been around for a long time, ground source heat pump has shown great advantages in energy saving and emission reduction. Whether it is design principle or normal use, ground source heat pump has carefully created a comprehensive user experience. , What are the methods of ground source heat pump maintenance? How to carry out the repair and maintenance of the ground source heat pump?
From the appearance, check the connection of the inlet and outlet valves of the ground source heat pump to see if there is leakage. During the test, pay attention to the sound of the ground source heat pump running, and judge according to the sound of the operation.
The maintenance of the condenser focuses on the cleaning of the condenser, and the cleaning of the cooling water should be guaranteed. The cooling water can be cleaned with some chemical cleaning agents to ensure that a large amount of scale does not form in the heat transfer tubes. Cleaning is divided into two methods: physical cleaning and chemical cleaning. Physical cleaning is to clean the end cover and water chamber of the condenser to ensure Neat and clean, there will be no rust or scale, and chemical cleaning refers to the use of some chemical cleaning agents to ensure uniformity during cleaning, rinse thoroughly with clean water, and do not leave residues.
Check the scaling of the evaporator, and do a good job of draining and replacing the water. When cleaning the evaporator, the blowdown valve of the evaporator should be opened to discharge the sludge inside. If necessary, the blowdown ball valve can be removed to increase the blowdown outlet. When using in winter, it is necessary to prevent the damage of the generator caused by water freezing. When discharging sewage, you can follow the following steps: run the water pump for 10 minutes, check the water quality at the sewage outlet, and judge the cleaning situation according to the water quality. Not good, you can choose to refill the water after draining, re-run, and check after running.
The service life of the ground source heat pump is very long, up to 20 years or higher, which is twice as long as that of the general air conditioning system. If the user can do a better maintenance work in the process of using the ground source heat pump, It can greatly extend the service life of the ground source heat pump, and at the same time, users pay attention to some operation methods in daily use, and the failure of the ground source heat pump during use will be greatly reduced.
