The overall cost performance ratio is high, and the advantages and disadvantages are listed as follows:
advantage:
1. Energy conservation and environmental protection: light commercial heat pumps can make full use of a large amount of heat energy in the air and generate more heat on the basis of consuming a small amount of electricity;
2. Safety and comfort: the overall design breaks through the disadvantages of the split design of the external unit water distribution tank of the traditional heat pump water heater, which can make the system more stable and reliable;
3. Large capacity design: users can enjoy hot water supply as soon as they open it, and meet the needs of multiple water points at the same time.
Disadvantages:
1. Large size: it needs to be installed on the ground or on the roof, which has high requirements for the home environment;
2. Frosting: obvious regional characteristics, because it depends too much on the ambient temperature, it is easily affected by the ambient air environment;
3. The compressor is easy to burn out: at present, the circulating heating system is widely used in the air energy water heaters on the market. When operating under high temperature and pressure, the compressor is easy to be aged and carbonized. If the lubrication effect of the system is not good, the compressor is easy to burn out;
4. Heat exchangers and casing heat exchangers are easy to scale and fracture: the outlet water temperature can reach 50 to 60 degrees, and scale is easy to occur within this range.
