According to the data of market research institutions, the top ten brands of air energy heat pumps in the domestic market are: TCL Intelligent HVAC, Gemei Yue, Finney, Paiwo, Aokelai, Nuentai, Changling, Zhongguang Oates, etc. These brands have a certain share and reputation in the market, but when we buy air energy heat pumps, in addition to the brand, we should also consider the following aspects:
1. COP value.
COP value, in simple terms, is the ratio of the cooling heat produced by the air energy heat pump to the total input power. Under the same operating conditions, the higher the COP value, the higher the efficiency and the more energy saving. It is recommended that you buy air energy heat pump products with large COP value. For example, TCL air energy heat pump, double first-stage energy efficiency (IPLV(H)=3.).44，iplv（c）=4.42) A heating season can help users save about 30% of heating costs.
Second, comprehensive performance.
With air energy heat pumps, we need to consider their electrical safety, mechanical safety, and environmental safety. At the same time, it is also necessary to consider its compatibility with people and the environment. For example, when the place where we live is too cold, we should choose a TCL air energy heat pump that can intelligently defrost, prevent freezing and cold, and operate stably at minus 35 to avoid the problem of heating not heating.
3. Dimensions.
Normally, most of the air energy heat pump units are located on the outdoor sunny side. Therefore, it is necessary to consider the spacing between the equipment and the surrounding wall, and the spacing between the equipment to determine whether the selected equipment size meets the size requirements of the equipment layout. Under the premise of the same performance, the smaller size of the unit should be preferred to reduce the footprint of the equipment.
To sum up, when choosing the right air energy heat pump, in addition to referring to the top ten brands of air energy heat pump, we should also consider multiple factors to avoid being deceived. Therefore, it is recommended to consult a professional engineer or manufacturer before purchasing to protect your own rights and interests.
