A. Noise of main engine
There may be two reasons for buzzing during the operation of air-energy water heaters: improper installation of water heaters or problems with compressors.
1. Installation inappropriate: If the noise of water heater is similar to metal impact, it may be caused by improper installation, such as unstable bracket, or the contact between the casing and the copper tube, which produces resonance under the vibration of the compressor driving the vibration of the copper tube.
Solution: We can adjust the bracket to make the unit stable, isolate the casing from the copper tube, avoid collision, and eliminate noise.
2. Compressor failure: If the water heater buzzes, it may be due to compressor problems, such as improper exhaust into the air, leading to compressor imbalance, resulting in buzz noise.
Solution: Contact the staff as soon as possible, empty the air in the compressor with a vacuum pump, check whether the inside of the compressor is clean, and then add refrigerant and compressed oil. In addition, a layer of silent cotton in the outer shell can also minimize noise.
B. Low Water Temperature
There are four reasons for the low water temperature: insufficient refrigerant, excessive scale accumulation, poor installation location, and excessive dirt on evaporator fins.
1. Insufficient refrigerant: In order to complete heating of air-energy water heater, refrigerant must be used as intermediate medium to continuously absorb heat in the air. Therefore, the lack of refrigerant will lead to a decrease in the heating capacity of water heaters, which will lead to a drop in the temperature of hot water.
Solution: In this case, you can contact air energy after-sales personnel to supplement refrigerants.
2. Excessive accumulation of scales: excessive accumulation of scales in air-energy water heaters will occupy the space that should belong to hot water, resulting in less hot water. Because of the scale, the thermal conductivity of the water heater becomes worse, which affects the overall heating effect of the air energy water heater.
Solution: It is suggested that we contact technicians in time and regularly clean the air-energy heat pump equipment.
3. Installation location is not well chosen: Air energy water heater needs to absorb heat in the air to make heat. Therefore, the main engine of the air energy water heater should be installed in the position of good air circulation, which is more conducive to the heat absorption and heating of the air energy heat pump.
Solution: If the outlet water of the air energy water heater is not hot, we can consider installing the air energy exterior machine on the balcony, outdoor platform and other places, so as to obtain more appropriate temperature and air circulation, and ensure the efficient heating of the air.
4. Excessive fouling on the fins of evaporators: Air-energy water heaters need to contact the air through the fins of evaporators to absorb the heat energy in the air. In the long-term work process, dust, hair and other substances in the air may cover the fins, affecting the heating of air energy, thereby affecting the water temperature.
Responding methods: Professionals should be regularly invited to clean up the air power units to ensure heating efficiency.
