Maintenance tips for air source heat pump units, worth collecting

With the development of heat pump technology, the use of air source heat pumps for cooling, heating and hot water services is becoming more and more popular. In terms of household use, air-source heat pumps can cool, heat, and provide hot water; in terms of business, air-source heat pumps are still not inferior, and they can be seen in schools, hospitals, office buildings, commercial buildings, swimming pools, etc.

In the HVAC industry, air-source heat pumps quickly occupied the market and became a rising star.

The air source heat pump unit is composed of a host, a water tank, a water pump and other components. As a large central air-conditioning system, daily maintenance is essential if it is to be used for a long time. So how do we maintain air source heat pumps in daily life?

Since most air source heat pump units use water as the medium, scale is easily formed during the water conversion and transportation process.

Therefore, the waterway and waterway filter must be cleaned regularly to avoid scale accumulation causing unit failure. When cleaning scale, if there is less scale, you can remove it yourself.

If the scale is too thick, you need to find a professional to clean it. You must not use chemicals to clean it yourself, because if the chemicals are not used properly, the pipes will be corroded by the chemicals. thus producing adverse effects.

The area around the unit should be kept clean and avoid storing debris. Avoid blocking the air outlet and affecting heat exchange efficiency.

Clean the water tank regularly. As a water storage component, the water tank must inevitably have foreign matter entering the water tank following the water flow.

After precipitation, a large amount of foreign matter will accumulate at the bottom of the water tank.

Therefore, we need to clean the water tank regularly to avoid unit failure. When cleaning the water tank, clean the water tank directly, discharge the sewage directly, and wait until the water outlet of the water tank is filled with clean water. If the scale is difficult to clean, please go directly to a professional scale cleaning company to clean it.

Regularly check whether the power cord of the unit is connected properly. Electricity has brought us a lot of convenience, but it is also a deadly medium for our human body.

If the power cord on the host is connected abnormally, it can easily lead to leakage and endanger life. Remember to check the unit’s power cord connection every time before turning it on and off. If there is any abnormality, please replace it in time.

Regularly check water pumps and regulating valve equipment. The water pump is an important component for transporting water.

When it fails, it can easily affect the normal operation of the unit, so the inspection of the water pump is essential.

The most important thing is the maintenance and upkeep of the main unit, because once there is a problem with the main unit, the entire unit will not be able to provide heating, cooling and hot water services.

When starting up, listen to the sound of the host. If the sound of the host is too loud, it is likely that the compressor is faulty and needs to be repaired in time.

At the same time, the fins must be cleaned in time. Generally speaking, we only need to use a high-pressure hose in an air gun holster to send high-pressure gas from the top of the fin downwards into the space between the fins.

Because of the reaction force of high-pressure gas, the high-pressure hose moves irregularly between the fin gaps.

At the same time, the dust adhered to the fins is also blown away or loosened by the high-pressure gas, and then washed downward with water from the top of the fins.

The blown or loosened dust flows along the water flow to the condensation tank, and the sewage is discharged to the drain pipe, gradually Clean the fins repeatedly to ensure that one side of the fins is clean; if the fins are very dirty, after the above cleaning process, spray the fins with aluminum fin cleaning agent solution and wait 3-5 minutes after spraying. Rinse with clean water.

After rinsing, the fins will show a metallic luster.

At this point, I believe everyone has a certain understanding of the maintenance of our air source heat pumps. Of course, no matter how good the maintenance is, it cannot be compared to choosing a reliable product when choosing.
