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°C while the leaving water temperature range is 20~60°C.
The S therm 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°C),
SCOP class A++(55°C) 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 CO

emission. Ranged
from 4.0kW~9.5kW, 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.
(4) Values of resistance to compressor status:
4/6kW——UV/VW/UW:1.67±7%Ω
8/10kW——UV/VW/UW:0.99±7%Ω
◆
High-efficiency Component(Inverter pump, Inverter fan, Plate heat exchanger)
(1) The A-class high-efficiency inverter water pump which complies with the European ErP directive, can
control the running frequency based on the actual load. Therefore, it can enhance the operation efficiency
and control the water temperature more accurately.
(2) The DC inverter fan can control the air volume accuratately and make the system run more stably and save
more energy.
(3) The high-efficiency plate heat exchaner will improve the unit’s performance largely.
