Efficient air source heating and cooling heat pumps

HISEER AW13/B-DPNHS air-water heat pump with standard cooling function, designed and tested by European standard EN14511, approved by TUV china branch. Characterized by competitive price, significant high efficiency, perfect running performance. It includes internal Wilo water pump, stainless steel cabinet, auto start emersion heater by the outside temperature.

Air-source heat pumps, often used in moderate climates, use the difference between outdoor air temperatures and indoor air temperatures to cool and heat your home, at the same time to supply domestic hot water.

HISEER heat pumps adopt the following world famous parts:

Siemens controller Hitachi scroll compressor SWEP or GEA plate type heat exchanger Emersion thermal expansion valve Emersion dry filter Schneider A/C contactor Honeywell R410a refrigeration

Air source heat pumps use the refrigeration process to transfer low grade energy from the air outside into high grade energy used for heating and domestic hot water. Even at temperatures as low as -20˚C, an air source heat pump can supply significantly more energy than it uses – and with no local C02 emissions, it helps reduce impact on the environment.

An ASHP system consists of a compressor and a carefully matched evaporator coil and heat exchanger. A refrigerant liquid which circulates within the system has a boiling point as low as minus 40˚C and evaporates when absorbing heat from the outside air. It is possible to extract considerable heat from the air at temperatures as low as minus 15˚C. The resulting refrigerant gas is then compressed adding more heat energy and raising its temperature to around 75˚C. This heat is then passed via the heat exchanger into water and used to provide space heating through radiators as for conventional heating systems, or via underfloor heating systems.

Heat pumps are measured by their coefficient of performance (COP). The COP for air source heat pumps is very similar to that for ground source heat pumps at approximately 2-4. With a COP for instance of 4, 4 units of heat are produced for every 1 unit of electricity consumed. (The three free units of heating were extracted from the outside air). Even with ambient air temperatures of -10 to -15 degrees Celsius, an air source heat pump can extract useful heat (i.e. > 1 unit of heat generated per unit of electricity consumed).
