How to maintain air source heat pump?

The air source heat pump is mainly a water system, many times, the effect is not good because of the water system on the problem. If you want to make the heat pump system run more stable and even make the system last longer, you need to perform maintenance. Let's take a look at how to maintain an air source heat pump.

Here is the content list:

• Daily inspection

• Maintenance of main structural components

• Maintenance of main electrical components

• Maintenance of main water circuit components

Daily inspection

• Check whether the air source heat pump line controller button is sensitive and whether there is any display fault.

• Before the air source heat pump is turned on, check each temperature parameter, switch status, and load output.

1. The temperature display does not differ much from the ambient temperature.

2. The high-pressure and low-pressure switches are normally closed, and the water flow switch is normally open.

3. The load display is closed.

• Check whether the voltage is normal before turning on the machine.

• After turning on the machine, check whether the water air source heat pump pressure is normal, listen to each load start whether there is a strange sound and run smoothly to check whether the current is consistent with the nameplate identification.

• Check whether the parameters of the air source heat pump are in the normal range after the operation.

Maintenance of main structural components

Compressor: disassemble the junction box, check whether the terminals are in contact with tight and whether there are signs of rusting and burning, and detect whether the resistance value between the three-phase windings is the same.

Fin: check whether the fins are dirty and blocked, clean them in time to keep them clean

Casing: check if there is a scale, the scale needs to be removed in time.

Maintenance of main electrical components

Air switch, AC contactor, and relay general inspection: air source heat pump terminals are tight, rust, and burn black, close the switch, check whether the input and output of each phase of the electrical terminals are connected; AC contactor and relay check whether the coil is sensitive and completely sucked.

Capacitor: check whether the air source heat pump is bulging and leaking oil.

Mainboard: check whether the air source heat pump power light is on, whether the fuse is blown, and whether the board surface has burned black traces

Wire controller: check whether the keys are sensitive, whether the interface is incomplete, and whether the temperature can be set.

Transformer: check whether the primary voltage and secondary voltage of the air source heat pump are in line with the nameplate.

Maintenance of main water circuit components

Water replenishment device: check whether the replenishment pressure of the air source heat pump is more than two kilograms and whether the check valve is stuck.

Filtration device: check whether the filter is dirty and blocked and needs regular cleaning.

Exhaust device: check whether the air source heat pump can be exhausted normally, and if it cannot be exhausted normally, it should be disassembled and cleaned with the filter inside.
