High COP in low temperature air to water EVI air source heat pump
1. Dual high-efficiency heat exchangers, combined with special water heat exchanger, can run in ultra-low tmperature with high COP and High heating capacity.
2.Safety, energy saving, no pollution, will not affect by environmental temperature. Absorbing heat from Water and air, will increase the heating coefficent of performance. Installation is simple, low operation and maintenance costs.
3.Used for waste heat recycling, water reuse, groundwater utilization and so on.
4.With memory function when emergency cutoff, and will automatically working when have emergency, no need to power on by hand.
5.When the environment temperature is too low, the microcomputer automatically start to defrost.
