Low temperature mono-bloc air to water heating pump system for Chinese Heat Pump

Low temperature mono-bloc air to water heating pump system

When the ambient temperature drops to below zero degree in winter, the normal air source heat pump can not run stably caused by the system low evaporated temperature, small gas absorption , small system gas flow and unstable superheat degree, etc . So that the air source heat pump’s heating output is low , the system runs unstably , even worse to cause the compressor damaged. Normal air source heat pump can not meet the heating requirement in the cold area in winter. So, the market for the heat pumps that can work under low ambient temp. is promising.

Low temperature air source heat pump AW13/L-DPNHE, with internal Wilo water pump and 3KW electric heater, 380-415V/3/50Hz, R410a unit, all the parts installed into one cabinet make it easy to be installed, world famous parts assure its high quality as well as stable running.

*SWEP or GEA plate type heat exchanger

*Schneider A/C contactor

*Saginomiya low pressure switch

*Carle pressure sensor

*Honeywell R410a refrigeration

HISEER low temperature air source heat pump AW13/L-DPNHE, adopt Hitachi EVI compressor, can be used at -20 degree outside temperature. The injection new technology make it possible that, even at -15 degree, the efficiency of the heat pump can reach 1.9. This is the ideal product to be used at the rather cold winter area.

AW13/L – DPNHE

HISEER, the brand name itself means high seasonal energy efficiency ratio.

Impressed by the founder’s specialist knowledge and experience at refrigeration fields, helped by the closed cooperation with engineers from world famous companies such as Hitachi, Siemens, SWEP, Honeywell, Emerson, etc. HIEER management team is keen to committed innovation to develop low carbon emissions heat pumps to fight for the world warming and power shortage. HISEER heat pumps, such as air source heat pumps, injection low temperature air to water heat pumps, geothermal ground source heat pumps are changing our ways of living, to reduce our foot print. HISEER is consistently create new possibilities to develop new technology for reducing carbon emissions, enhance people’s comfort and improve lives.
