Description
Technical field
The utility model relates to air-conditioner, is specifically related to a kind of highly effective air source heat pump air-conditioner.
Background technology
At present, the air source heat pump air-conditioner by refrigeration compressor, four-way change-over valve and the expansion valve of indoor heat exchanger, outdoor heat exchanger and configuration are formed because system architecture is simple, easy for installation, and is widely used.But this heat pump air conditioner is owing to adopt high temperature compressed machine in the middle and high back pressure type, when outside air temperature is lower than after 0 ℃, its operating efficiency reduces with evaporating temperature and descends, so present air source heat pump air-conditioner does not increase auxiliary electric heater unit, is difficult to satisfy the requirement of winter low temperature heating; And when outside air temperature reaches more than 30 ℃, make its refrigerating efficiency very low again owing to condensation temperature is too high, be difficult to realize the refrigerating operaton of efficient energy-saving.Become the present air source heat pump air-conditioner of restriction thus and under low temperature environment and hot environment, efficiently heat the bottleneck of using with refrigerating operaton.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of at the effective highly effective air source heat pump air-conditioner of heat supply and refrigerating operaton still under 0 ℃ to-20 ℃ the low temperature environment and under the hot environment more than 30 ℃.
The technical scheme that realizes above-mentioned purpose is: a kind of highly effective air source heat pump air-conditioner, and it includes four-way change-over valve, expansion valve and the indoor and outdoors heat exchanger of refrigeration compressor and phase configuration, and its described refrigeration compressor adopts low back pressure type cryogenic compressor; The outdoor heat exchanger of its heat pump air conditioner is by casing and place heat exchange coil, water spray system and blower fan in the casing to form.
The technical solution of the utility model also comprises: dispose the liquid level water replanishing device in the bottom of casing; In casing, be provided with water fender.
The utility model adopts the low back pressure type cryogenic compressor that is suitable for the low temperature environment heating operation to form air source heat pump, does not carry out effective heating operation so that heat pump air conditioner does not increase auxiliary electric heater unit under 0 ℃ to-20 ℃ low temperature environment; And use fountain evaporation, condensing heat exchanger as outdoor air heat exchanger, utilize the shower water vaporization to take away the high-temperature gas cold-producing medium latent heat that compressor is discharged, still can the highly effective refrigeration operation when being implemented in environment temperature and being higher than 30 ℃, thereby enlarged effective temperature range of operation of air source heat pump air-conditioner, improved the applicable performance and the operating efficiency of air source heat pump air-conditioner.
Description of drawings
Fig. 1 is an example structure schematic diagram of this highly effective air source heat pump air-conditioner.
Fig. 2 is another example structure schematic diagram of this highly effective air source heat pump air-conditioner.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing 1, this heat pump air conditioner includes four-way change-over valve 2, expansion valve 4 and the cold hot air type indoor heat exchanger 3 of refrigeration compressor 1 and configuration with it, and its refrigeration compressor 1 adopts low back pressure type cryogenic compressor; The outdoor heat exchanger of its heat pump air conditioner is arranged to fountain condensation, evaporating heat exchanger, by casing 8 with place heat exchange coil 5, water spray system 6 and blower fan 7 in the casing to form.Dispose water replanishing device 9 in the bottom of casing 8, in casing, be provided with water fender 10.During concrete enforcement, the heat exchange coil 5 of its outdoor heat exchanger can adopt various types of high efficient heat exchanging coil pipes, and can add heat exchange wing, fin on its coil pipe.Water spray system 6 is made up of water circulating pump, water filter, nozzle and pipeline.Casing 8 is provided with air inlet, and cisten mechanism is arranged in the bottom of casing, in the top of casing 8 air outlet that cooperates with blower fan is set.Liquid level water replanishing device 9 can adopt float-ball type or other type level control structure for water.Water fender 10 can adopt setback template water fender.
The difference of accompanying drawing 2 embodiment and accompanying drawing 1 embodiment is that the version of indoor heat exchanger 3 is cold-producing medium and ability of swimming heat exchanger, what export is not cold and hot wind, but hot and cold water, heating and cold supply system that its indoor heating and cooling are made up of air conditioner end equipment 11 and water pump 12 are finished.
In conjunction with the accompanying drawings operation principle of the present utility model is described as follows:
As accompanying drawing 1, when the utility model winter heating moved, the dotted line path of four-way change-over valve 2 was connected with system, the solid line path blockade.The refrigerant vapour that compressor 1 is discharged through four-way change-over valve 2 dotted line paths to exporting surface cooling heat exchanger 3, to indoor blowing hot-air heating, with condensation heat be released to indoor after, refrigerant gas is condensed into liquid refrigerant heat exchange coil 5 to outdoor heat exchanger after expansion valve 4 throttlings, this moment, outdoor heat exchanger was used as the evaporimeter use, through blower fan 7 circular chamber outer air, liquid refrigerants evaporation in the coil pipe 5 absorb become again behind the airborne low-temperature heat quantity gaseous refrigerant through another dotted line path of four-way change-over valve 2 to the compressor air suction end, sucked the back recompression by compressor and repeat the above-mentioned process that heats.
Summer is during refrigerating operaton, the dotted line path blockade of four-way change-over valve 2, and the solid line path is connected with system.The gaseous refrigerant that compressor 1 is discharged is through the solid line path of four-way change-over valve 2 heat exchange coil 5 to outdoor heat exchanger, the high-temperature gas cold-producing medium is earlier after heat exchange coil 5 non-spray coil sections cooperate wind cooling temperature lowering by blower fan 7, the spray coil section that enters coil pipe 5 again sprays efficient cooling through water spray system 6, flash to water vapour after the cooling water heat absorption, the condensation latent heat in the coil pipe is taken away by air.Through condensed liquid refrigerant after expansion valve 4 throttlings to indoor surface cooling heat exchanger 3, airborne heat in the evaporation absorption chamber, to the indoor cold wind refrigeration that blows out, liquid refrigerant after heat absorption becomes gaseous refrigerant again, be back to the suction end of compressor 1 through another solid line path of four-way change-over valve 2, repeated above-mentioned refrigerant compression operation after being sucked by compressor.
Accompanying drawing 2 and accompanying drawing 1 different are in the output heat exchanger 3 of accompanying drawing 2 to be cold-producing medium and water form heat exchanger, to be output as cold water and hot-water type refrigeration and heating system.When winter heating moved, through the heating water heating of condensation heat release with heating loop, heating water pump 12 utilized heating water to heat heating through pipeline and terminal heating equipment 11; Summer through the cold-producing medium after expansion valve 4 throttlings after heat exchanger 3 flush distillations absorb heat in the secondary refrigerant water, with chilled water freezing become chilled water through air conditioning terminal fan coil 11 to indoor refrigerating operaton.
Compressor 1 of the present utility model should adopt frequency conversion or increase Unloading Control, and expansion valve should adopt electric expansion valve.
