DC Inverter Monobloc Heat Pump For Heating & Cooling Common Failure And Maintenance Methods

Air energy heat pump in the process of use, it is inevitable that there will be problems. As a senior after-sales engineer, it is easy to fall into empiricism. Different causes may cause the same fault. Therefore, we need to consider all the possible causes of high-voltage failures and eliminate them. The following describes the troubleshooting methods for a common DC inverter monobloc heat pump for heating & cooling. I hope it can help you.

Here is the content list:

• High voltage protection

• Unit component failure

• Water flow protection

High voltage protection

The unit panel of the air source heat pump shows high-pressure protection. There are many reasons for this failure, which can be divided into water system problems and unit component failures. Eliminate engineering installation errors. If the unit is reported for high-pressure protection after normal operation for a while, the water volume is often small, which may be the dirty plugging of the Y-type filter or casing scaling, which needs to be investigated separately. The main engine stops running and the valves at the front and rear ends of the filter net are closed to avoid large amounts of water flowing out. Unscrew the plug of the Y-shaped filter using an adjustable wrench and pull out the filter. Rinse the filter in tap water and put it back into the pipeline. Be sure to open the front and rear valves before starting. If the filter is excluded, it is necessary to consider the possibility of causing scaling. Especially in some areas with hard water quality, the possibility of scaling is higher. To check to scale, just disassemble the inlet and outlet pipes of the main engine. Once the high-pressure fault caused by casing scaling is found, contact professional limescale cleaning master door cleaning.

Unit component failure

Common air source heat pump unit failures may not result in high-pressure protection. Check whether the fan works normally. If the fan does not rotate, it may be that the fan capacitor or relay is broken. You only need to adjust the multimeter to gear or check the gear. If the high voltage switch is found to be disconnected immediately after the restart, there is no doubt that the high voltage switch itself is broken, replace one. If the unit is used for many years, the fins are covered with dust may also cause high-pressure protection, just clean up with water to troubleshoot.

Water flow protection

Water flow protection failures are the most common in all engineering installations. Regardless of installation, there are generally two possibilities for water flow protection: the water system does not flow and the water flow switch itself is damaged. Resulting in water flow failure, often air source heat pumpwaterway problems. Therefore, how troubleshooting quickly and accurately needs a certain logical sequence.

The above is the common failure and maintenance method of DC inverter monobloc heat pump for heating & cooling, but it is best to contact professional maintenance.
