EVI Heating Technology in Split VersionSplit EVI heat pumps are particularly suitable for cold areas. Not only because of the EVI (enhanced vapor injection) heating technology,Website:http://www.speedy-energy.com,  but also due to the split design: the outside unit contains evaporator and fan motor; Compressor, condenser and control system are...

Precise Output Matching,Website:http://www.speedy-energy.com, High EfficiencyFor a given house, the heating load which is mainly affected by the outside temperature is always changing during a day or even a heating season. We normally control the ON/OFF time of a normal heat pump to match the heating load. The benefit of a DC inverter heat pump is...
