Low temperature heat pump water heater

DEAKON low temperature heat pump
1) Works in low temp.
2) High-efficiency, beautiful and fashionable
3) Eco-friendly
4) Instant heating
 
Low temperature air source heat pump system provides house heating (hot water, floor heating, radiator) solution for residential and commercial application, especially in cold area.
 
1. U-type and double-deck evaporator increase absorber area.
2. Heating coil for compressor to warm up and ensure compressor start-up at low surrounding temp.
3. Application of the enhanced vapor injection technology in Copeland compressor (ZW), ensure the heat pump can work with high efficiency when -15 ℃ and the COP will be above 2.3. 
4. Application of plate-type and double-pipe heat exchanger can increase the heat exchange area.
5. The top grade EEV can control the refrigerant flow accurately and enhance the machine performance, which can help to work in low temperature with high efficiency.
6. It can defrost automatically while frosting on evaporator surface.
