1) Look at the brand
Air energy (source) heat pumps are products with high technical requirements. Therefore, when choosing a brand, it is recommended to choose a professional brand with a good reputation, such as Midea , Hisense, Hitachi, Mitsubishi Heavy Industries, Haier, Ouke Air Conditioning, etc. In addition to choosing a trustworthy brand, you also need to consider the background and strength of the compressor technology provider.
Emerson Environmental Optimization Technology, a heating expert from the United States, owns the patent for Copeland TM EVI vortex intense heating technology. It focuses on the "intense heating core" and can still maintain air energy even under extreme climate conditions. (Source) The heat pump system operates normally and stably, provides the required heat, is clean and energy-saving.
2) Look at the technology
When ordinary air energy (source) heat pumps are used in cold areas with lower temperatures, the drop in ambient temperature causes the evaporation temperature to drop and the refrigerant flow rate to drop. The thermal capacity is greatly reduced. At the same time, the increase in exhaust temperature caused by the increase in compression ratio will also cause a decrease in compressor reliability. Choosing a low-temperature air energy (source) heat pump equipped with Copeland TMEVI vortex intense heating technology/EVI vortex intense heating technology can solve this technical problem. In addition, in areas with hot summers and cold winters, although the ambient temperature is not too low, the insulation performance of many residential building envelopes is low, resulting in increased cooling and heating loads. A large amount of auxiliary electric heating is required to meet the heating needs. In view of this, For this type of housing, it is also recommended to be equipped with Copeland TMEVI vortex intense heating technology/EVI vortex intense heating technology, which can significantly reduce energy consumption while satisfying comfortable life.
