At present, the air source heat pump air-conditioner of forming by compressor, four-way change-over valve, expansion valve, outdoor table cold heat exchanger and indoor table cold heat exchanger, when outside air temperature is low to moderate environment heating operation below 0 ℃, efficient obviously reduces, therefore needing increases auxiliary electric heater unit, otherwise just can not satisfy the heating requirement; When outside air temperature was higher than 30 ℃, because the heat pump condensation temperature is too high, its refrigerating operaton efficient was also very low on the contrary, and power consumption obviously strengthens, and is difficult to carry out refrigerating operaton efficiently.The environment temperature scope of application of present air source heat pump is restricted, becomes the widely used obstacle of restriction air source heat pump air-conditioner.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of suitable environment temperature range wide, the efficient water-cooled air source heat pump air-conditioner of heating and refrigerating operaton still under low temperature environment and hot environment.
The technical scheme that realizes above-mentioned purpose is: a kind of water-cooled air source heat pump air-conditioner, it includes the air source heat pump system of being made up of compressor, four-way change-over valve, expansion valve, outdoor surface cooling heat exchanger and output heat exchanger, its described compressor is low back pressure type cryogenic compressor, on the refrigerant loop of outdoor surface cooling heat exchanger and be connected to a cold-producing medium ability of swimming heat exchanger, the pipeline that the secondary terminals of its heat exchanger is configured water pump connects cooling tower.
The utility model adopts low back pressure type cryogenic compressor, so that air source heat pump need not to increase auxiliary electric heater unit and is suitable for the efficient heating operation of low temperature environment; And, realize the highly effective refrigeration operation of air source heat pump under hot environment by configuration cooling tower water-cooling apparatus.Thereby widened the temperature scope of application of air source heat pump, improved its work operational efficiency, can save a large amount of electric energy, helped the wide popularization and application of air source heat pump.
Description of drawings
Fig. 1 is an example structure schematic diagram of the present utility model.
Fig. 2 is another example structure schematic diagram of the utility model.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing 1, the utility model includes the air source heat pump system of being made up of compressor 1, four-way change-over valve 2, expansion valve 4, outdoor surface cooling heat exchanger 5 and hot and cold water output heat exchanger 3, and its compressor 1 is low back pressure type cryogenic compressor; On the refrigerant loop of outdoor surface cooling heat exchanger 5 and be connected to a cold-producing medium ability of swimming heat exchanger 6, the pipeline that the secondary terminals of its heat exchanger 6 is configured water pump 8 connects cooling tower 7.As accompanying drawing 1 embodiment, and connect in the pipeline of cold-producing medium ability of swimming heat exchanger 6 and be equipped with by- pass valve control 9 and 10, matching with output heat exchanger 3 is equipped with the hot and cold water air-conditioning system of being made up of air conditioner end equipment 12 and water circulating pump 11.
Accompanying drawing 2 only is that with the difference of accompanying drawing 1 heat exchanger 3 for the surface cooling heat exchanger, directly freezes or heating to indoor blast-cold, hot blast mode.Many of its heat exchanger 3 configurations can be formed many formulas of holder air-conditioning system.
Operation principle accompanying drawings of the present utility model is as follows:
As accompanying drawing 1, during Winter heat supply, the high temperature refrigerant gas that compressor 1 is discharged through the dotted line path of four-way change-over valve 2 to the primary coolant side loop of exporting heat exchanger 3, utilize refrigerant vapour that the heating water of secondary water side is discharged the condenser heat heating, hot water moves through water pump 11 and pipeline to air conditioner end equipment 12 heat supply heatings.Gas refrigerant after the heat release is condensed into liquid refrigerant, after expansion valve 4 throttlings to outdoor surface cooling heat exchanger 5, low-temperature heat quantity in the evaporation absorption chamber outer air, the cold-producing medium that becomes gaseous state to conversion valve 9 after another dotted line path of four-way change-over valve 2 to the suction end of compressor 1, sucked the back recompression by compressor and repeat above-mentioned heating operation circulation.
Summer is when freezing, the high-temperature gas cold-producing medium that compressor 1 is discharged through the solid line path of four-way change-over valve 2 after heat exchanger 6 cold-producing medium primary side loops discharge condensation heat to the secondary side cooling water, the liquefy cold-producing medium evaporates the heat that absorb in secondary side chilled water to expansion valve 4 throttlings after export heat exchanger 3 primary circuits through conversion valve 10, secondary side water is become chilled water, pass through air conditioner end equipment 12 through water pump 11 and pipeline, finish indoor refrigerating operaton.Cold-producing medium after the evaporation becomes again and is gaseous refrigerant, is back to compressor 1 air entry through another solid line path of four-way change-over valve, and after being sucked by compressor, recompression repeats above-mentioned kind of refrigeration cycle.
The principle of the heating of accompanying drawing 2 embodiment and refrigerating operaton principle and accompanying drawing 1 embodiment is basic identical, only be different from the form of output heat exchanger 3, Fig. 1 realizes refrigeration and heating with the output hot water or cold water, and accompanying drawing 2 output is hot and cold wind, realizes indoor refrigeration and heats heating operation.
Accompanying drawing 2 winter heatings, the high-temperature gas cold-producing medium that compressor 1 is discharged through four-way change-over valve 2 dotted line paths to exporting heat exchanger 3, by blower fan to indoor blowing hot-air heating, after cooling off the cold-producing medium of liquefy after expansion valve 4 throttlings to outdoor table cold heat exchanger 5, behind the low-temperature heat quantity in the evaporation absorption chamber outer air, become gaseous refrigerant again through valve 9 and four-way change-over valve 2 another dotted line paths air entry, sucked back recompression circulation by compressor to compressor 1.
When accompanying drawing freezes for 2 summers, the high-temperature gas cold-producing medium that compressor 1 is discharged through the solid line path of four-way change-over valve 2 to heat exchanger 6, latent heat in the cold-producing medium is released in the water, condensed liquid refrigerant through switching valve 10 to expansion valve 4 throttlings to exporting heat exchanger 3, airborne heat in the evaporation absorption chamber, by blowing a cold wind over to indoor refrigerating operaton, the cold-producing medium that evaporation becomes gaseous state is back to the air entry of compressor 1 through another solid line path of four-way change-over valve 2, is sucked recompression by compressor and repeats above-mentioned circulation.The secondary cooling water side of heat exchanger 6 to cooling tower 7, in atmosphere, is finished water cooling operation in summer with condensation latent heat bulk storage in the water through water pump 8 and water lines.
