How to clean the air source heat pump if the heating effect is not goodHow to clean the air source heat pump if the heating effect is not good
With the improvement of people's living standards, air source heat pumps have become commonly used heating equipment in homes and commercial places. However, after using it for a period of time, you may encounter the problem of poor heating effect. So, how do you clean an air source heat pump?Below we will introduce it in detail from the following aspects.
1. The principle and structure of the air source heat pump.
An air source heat pump is a device that uses heat from the air to generate heat. It is mainly composed of compressors, condensers, expansion valves, and evaporators, among others. When the compressor works, it will compress the refrigerant into a high-temperature and high-pressure gas, then dissipate heat through the condenser and become a liquid at low temperature and high pressure, become a low-temperature and low-pressure gas after being depressurized through the expansion valve, and finally absorb the heat in the air in the evaporator, and then become a high-temperature and low-pressure gas again, and return to the compressor to continue working.
Second, the reason for the poor heating effect of the air source heat pump.
1.Evaporator dust.
The evaporator is an important component in an air source heat pump, which is responsible for absorbing heat from the air. However, after a period of use, a large amount of dust and microorganisms will accumulate on the surface of the evaporator, which will affect its endothermic effect. At this point, we need to clean the evaporator.
2.Poor heat dissipation of the condenser.
The condenser is one of the important components in the air source heat pump, which is responsible for dissipating heat from high-temperature and high-pressure gases into low-temperature and high-pressure liquids. However, after a period of use, a large amount of dust and debris will accumulate on the surface of the condenser, which will affect its heat dissipation effect. At this point, we need to clean the condenser.
3.Insufficient refrigerant.
Refrigerant is an important medium in an air source heat pump and is responsible for transferring heat in the recirculating system. However, after a period of use, the refrigerant may leak or be consumed, affecting its heating efficiency. At this point, we need to check the refrigerant charge and replenish it.
3. Cleaning method of air source heat pump.
1.Cleaning method of evaporator.
1) Turn off the power supply of the air source heat pump and open the inlet and outlet valves
2) Drain the water in the tank and rinse the surface of the evaporator with clean water
3) Gently scrub the surface of the evaporator with a soft-bristled brush
4) Rinse with clean water and dry with a clean towel
5) Turn on the power and check if the evaporator has been cleaned.
2.Cleaning method of condenser.
1) Turn off the power supply of the air source heat pump and open the inlet and outlet valves
2) Drain the water in the water tank and rinse the surface of the condenser with clean water
3) Gently scrub the surface of the condenser with a soft-bristled brush;
4) Rinse with clean water and dry with a clean towel
5) Turn on the power and check if the condenser has been cleaned.
3.Refrigerant charging method.
1) Turn on the power supply of the air source heat pump and open the refrigerant charging port
2) Connect the refrigerant bottle mouth with the filling port;
3) Open the cap of the refrigerant bottle and slowly pour the refrigerant into the filling port;
4) Close the filling port and the cap of the refrigerant bottle;
5) Turn on the power and check if the air source heat pump is working properly.
4. Precautions.
1.When cleaning and servicing an air source heat pump, be sure to turn off the power supply to avoid accidents
2.Do not wipe the surface of the parts too hard during the cleaning process to avoid damaging the device;
3.When charging the refrigerant, make sure that the purity and charge of the refrigerant are appropriate
4.In daily use, the equipment should be inspected and maintained regularly to ensure its proper operation.
