1.3 Product Features 
1.3.1 General 
It‘s a kind of integrated DC inverter unit that comprises cooling, heating and water heating functions, 
and  up  to  5.0  energy  efficiency.  It  adopts  R32  refrigerant  and  two-stage  compressor.  For  heating, 
ambient temperature range is -25~35
℃
  while the leaving water temperature range is 25~60
℃
. 
The  Versati 
Ⅲ
  unit  is  designed  specially  for  the  European  market  where  there  is  a  demand  for 
high-temperature water. Thanks to the dual-stage compression and enthalpy gain through gas injection, 
the heating energy efficiency at low temperature will rise up greatly with the leaving water temperature 
up to 60°C. The whole series of products strictly comply with EN14511,EUROVENT energy efficiency 
Class A and SCOP class A+++(35
℃
), SCOP class A++(55
℃
) with EN14825. Their COP can reach up to 
5.0. This unit can realize space heating and sanitary hot water supply through terminal units, like the fan 
coil unit, floor coil and radiator. Environment-friendly refrigerant R32 is adopted for the unit, with ODP of 
0 and quite low GWP (=675). Besides, the adopted heat pump technologies will reduce consumption of 
coal and other energy source and lower greatly CO2 emission. Ranged from 4.0kW~16kW, it is widely 
applicable to small and medium-sized apartment, large-sized villa etc. 
1.3.2 Features 
  Wide Operation Range 
  Heating: -25~35°C; Cooling: 10~48°C; Water Heating: -25~45°C 
  Unique Low-Temp Hi-heat Dual-stage Compressor 
1. Under low-temperature conditions, compared with the conventional compressor, the dual-stage 
low-temp hi-heat compressor will generate less loss of heat capacity and get higher energy efficiency. 
2. Floodback, high discharge temperature and other problems can  be completely avoided under 
low-temp conditions and the compressor‘s reliability will be enhanced greatly. 
3.  Dual-stage  compression,  dual-stage  throttling  and  intermediate  enthalpy  adding  through  gas 
injection will raise the leaving water temperature and improve the control accuracy.
