The technical scheme that realizes above-mentioned purpose is: a kind of air-conditioner that is fit to high or low outdoor environment temperature, it includes outdoor heat exchanger and indoor heat exchanger, match with two heat exchangers and to be equipped with the energy coupled heat exchanger, the once end of its energy coupled heat exchanger is connected with the refrigerant loop of outdoor heat exchanger through serial connection four-way change-over valve, compressor and expansion valve, forms air source heat pump.The secondary terminals of energy coupled heat exchanger is connected with the refrigerant loop of indoor heat exchanger through being connected in series other one group of four-way change-over valve, compressor and expansion valve, forms artificial source's heat pump.
The technical solution of the utility model also comprises: described energy coupled heat exchanger is equipped with lagging casing.
The utility model utilizes the outdoor heat exchanger and the indoor heat exchanger of heat pump type air conditioner, dispose an energy coupled heat exchanger to it, and two groups of compressors by disposing, four-way change-over valve and expansion valve, form two-stage heat pump type air conditioner with two evaporating temperatures and two condensation temperature operating conditions, its air source heat pump is not participated in indoor heating or refrigeration directly, but be used for obtaining the heat in the Cryogenic air or finish cooling, make the operating condition environment of a relative ideal for artificial source's heat pump, make artificial source's heat pump high energy efficiency than under heat or freeze, thereby realize heat pump type air conditioner the low temperature below-7 ℃ and under the hot environment more than 43 ℃ safety, efficiently heat or refrigerating operaton.
Description of drawings
Accompanying drawing is this air-conditioner structural representation that is fit to high or low outdoor environment temperature.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, the utility model includes outdoor heat exchanger 1 and indoor heat exchanger 7, and its outdoor heat exchanger and indoor heat exchanger can adopt surface cooling heat exchanger or other type heat exchangers.Matching with two heat exchangers is equipped with energy coupled heat exchanger 4, and its energy coupled heat exchanger can adopt the heat exchanger of various ways such as vertical disc pipe heat exchanger, shell-type spiral tube heat exchanger, double pipe heat exchanger, spiral heat exchanger and shell and tube exchanger.The once end of its energy coupled heat exchanger 4 is connected with the refrigerant loop of expansion valve 9 through serial connection four-way change-over valve 3, compressor 2 with outdoor heat exchanger 1, forms air source heat pump; The secondary terminals of energy coupled heat exchanger 4 is connected with the refrigerant loop of expansion valve 8 through serial connection four-way change-over valve 6, compressor 5 with indoor heat exchanger 7, forms artificial source's heat pump.
As accompanying drawing, energy coupled heat exchanger 4 of the present utility model is provided with lagging casing 10, is not is not scattered and disappeared with the energy of guaranteeing heat exchanger.Its lagging casing is fit to select the little forming materials that does not absorb water part of flame retardant type thermal conductivity factor.
During the operation of the utility model Winter heat supply, the high-temperature gas cold-producing medium that compressor 2 is discharged is through the dotted line path of the four-way change-over valve 3 once end to energy coupled heat exchanger 4, condenser heat is passed to the secondary terminals of heat exchanger 4, through after expansion valve 9 throttlings, delivering to outdoor heat exchanger 1 by the cold-producing medium of gaseous state liquefy after the condensation heat release, heat in the outer Cryogenic air of evaporation absorption chamber, the cold-producing medium that evaporation back becomes gaseous state by liquid state enters the suction side of compressor 2 through another dotted line path of four-way change-over valve 3, become the refrigerant gas of HTHP after compressed machine 2 compressions of the refrigerant gas of low-temp low-pressure again, repeat above-mentioned cold-producing medium circulation once more, the cryogenic energy in the outdoor air is delivered to energy coupled heat exchanger 4 continuously; And the high temperature and high pressure gaseous refrigerant that compressor 5 is discharged through the dotted line path of four-way change-over valve 6 to indoor heat exchanger 7, condenser heat is sent to indoor heating heating, the cold-producing medium of liquefy after the condensation heat release, after expansion valve 8 throttlings, deliver to the secondary terminals of energy coupled heat exchanger 4, evaporation absorbs by the air source heat of once holding output, become the cold-producing medium of gaseous state, enter the suction side of compressor 5 afterwards through another dotted line path of four-way change-over valve 6, be compressed the above kind of refrigeration cycle of repetition once more, realize to the heat supply heating operation of indoor highly effective rate ground.
The utility model is used for summer during refrigerating operaton, four-way change-over valve 3 and 6 commutations, and the solid line path is communicated with compressor, the dotted line path blockade.The high-temperature gas cold-producing medium that its compressor 2 is discharged through four-way change-over valve 3 solid line paths to outdoor heat exchanger 1, by heat exchanger 1 high-temperature gas cold-producing medium heat is distributed in the atmosphere, being condensed into liquid cold-producing medium once holds evaporation to absorb the secondary terminals heat by energy coupled heat exchanger 4 after expansion valve 9 throttlings, gaseous refrigerant after the evaporation is recompression after another solid line path of four-way change-over valve 3 is sucked by compressor 2 again, repeat above kind of refrigeration cycle, to be distributed in the outside atmosphere through outdoor heat exchanger from the heat of energy coupled heat exchanger 4, finish cooling work; And the high-temperature gas cold-producing medium that compressor 5 is discharged enters energy coupled heat exchanger 4 through the solid line path of four-way change-over valve 6 secondary terminals, cold-producing medium by liquefy after once end cools off is delivered to indoor heat exchanger 7 after expansion valve 8 throttlings, the heat that evaporation absorbs room air freezes, cold-producing medium after the gasification is sucked by compressor 5 through another solid line path of four-way change-over valve 6, compression repeats above-mentioned kind of refrigeration cycle once more, finishes summer to indoor refrigerating operaton.
