Lack of refrigerant

Refrigerant is our commonly known refrigerant, which is the key substance for the heating of air energy water heaters. In order to complete the heating of the air energy water heater, it is necessary to use the refrigerant to absorb heat from the air. In the long-term use of air-energy water heaters, there may be leakage of equipment refrigerant. After the refrigerant leaks, the heating capacity of the air energy is greatly reduced, and the water temperature naturally drops. At this time, it is necessary to contact the staff to properly supplement the refrigerant.

Excessive accumulation of scale

Air-energy water heaters are heated all the year round. In such an environment, it is easy to breed scale. Once a large amount of scale accumulates in the water heater pipe and the tank liner, it will occupy the space that would otherwise belong to the water heater. In addition, the thermal conductivity of the scale is not high, which will cause the overall heating effect of the air energy water heater to decrease, affecting the outlet water temperature. It is recommended to invite technicians to clean the door regularly.

Evaporator fin

Since there is a possibility of accumulation of dirt inside the water system, the air heaters that are in direct contact with the outside can also have the same evaporator fins. Air-energy water heaters need to contact the air through the evaporator fins to absorb the heat energy in the air. In general, the larger the area of contact between the evaporator fins and the air, the better the overall heating effect of the device. However, in the long-term work process, dust, hair and other substances in the air may cover the fins and affect the heating of the air energy. So how should it be cleaned? Very simple, turn off the water heater, spray the cleaning agent on the evaporator fins, and wipe it clean from top to bottom with a rag.

The installation position of the air energy water heater is not appropriate

Air-energy water heaters do not need to consume natural gas, but they need to absorb low-grade heat in the air. Therefore, its installation location is still very particular. Generally speaking, it is installed in a balcony, a window sill, a roof, etc., where the air temperature is relatively high and the air circulation is good, which is beneficial to the heating of the air energy. Conversely, if the air-energy water heater is installed in a dark and humid location, or if it is too close to the wall and the air is not well circulated, there may be cases where heating does not give force.
