Low Temperature Central Air Conditioner Heat Pump Efficiency In
Winter
About Central Air Conditioner Heat Pump
The design and manufacture according to state & industry standard.
The unit adopts high quality and efficiency semi-closed double
scroll compressor, high-quality condensed fan and reliable micro
computer control system. The unit can reach high operation
reliability by optional design, rational disposition and elaborate
assembly.
The air is the cold (hot) source for the unit; The Refrigerant
medium is water; The unit is a packed equipment with cooling and
heating. It can be used into the comfortable air conditioning
system as the cooled source, like market, residence, office
building, mansion, factory, hotel, hospital and so on. It can also
used into industrial air conditioning system such as electronic,
pharmacy, chemical, power system and machine industry.
There is single cooled type and heat pump type for the air cooled
(hot) water unit. The heat pump type can meet heating and cooling
functions. Multi-purpose for one unit is main feature for the heat
pump unit. So it can be used in the places that need heating
requirement but there is no heating equipment. The heat pump can be
instead of the boiler with pollution. It is a kind of energy
conservation and environmental protection products at present.
Central Air Conditioner Heat Pump Applications
in summer , 7C cool water circulate inside the system;
in winter, 50C hot water circulate inside the system.
It is more confortable than conventional AC unit
