Common problems with air source heat pumps

At present, air source heat pumps are widely used in various regions of our country, whether in industry, agriculture, home or office environment. Let Leomon Technology summarize the common problems with air source heat pumps and the corresponding problem solutions for everyone.

Common fault 1: Poor heating effect

Problem analysis: The original cause of the problem is mainly

1) Insufficient heat preservation effect of water system;

2) Lack of refrigerant;

3) Poor heat dissipation of the switch;

4) Insufficient water flow

Problem solving: check whether the heat preservation of the water tank meets the specified requirements; check the refrigerant, add a cooler; clear or replace the heat exchanger; increase the water volume of the water system.

Common fault 2: The unit does not operate

problem analysis:

1) Part of the power supply is short-circuited or not connected;

2) The unit control power fuse is blown.

Problem handling: turn off the power switch, check the power connection status of each device; replace the new fuse.

Common fault 3: The running state of the water pump is not normal

Failure analysis:

1) Water shortage in the water system; water shortage in the water system;

2) The water system valves are all open at the end;

3) The water filter is dirty and blocked.

Problem solving: Check the system water replenishment device, and replenish water to the system; fully open the water system valve; clean the water filter.

Common fault 4: The compressor stops working

Cause Analysis:

1) Power failure;

2) Compressor overheat protection;

3) The outlet water temperature is too high;

4) Insufficient water flow.

Problem solving: Check whether the compressor's power connection status is normal; the compressor may be overloaded due to the high water temperature set at the beginning, and temporarily stop working, and the outlet water temperature should be reset; clean the water filter to remove the air in the system .

Common problem 5: The fan does not work

Cause Analysis:

1) The fan motor is burned out;

2) The fan gear is stuck.

Treatment measures: replace the fan; replace the fan capacitor. Clean up all foreign objects inside the fan.
