Fig. 2 is another example structure schematic diagram of this air-conditioning and hot water apparatus.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing 1, the utlity model has main by compressor 1, four-way change-over valve 2, expansion valve 3 and air source heat pump air-conditioner indoor, that outdoor heat exchanger 4,5 is connected to form through refrigerant pipe.Its compressor 1 adopts low back pressure type cryogenic refrigeration compressor to adopt frequency conversion or increase Unloading Control.Expansion valve 3 adopts electronic expansion valve, and indoor heat exchanger 4 is the surface cooling heat exchanger.Spraying and sprinkling evaporation, the condensing heat exchanger of outdoor heat exchanger 5 for forming by casing 6 and the water spray system 9 that places blower fan 7, heat exchange coil 8 and configuration in the casing, water level control water replanishing device 10.The water spray system 9 of its heat exchanger is made up of the filter of water pump, water pipe and shower nozzle and configuration.Water level control water replanishing device 10 can adopt the control of float-ball type water level or other electronics mode water level control water replanishing device.Match with heat pump air conditioner and to be equipped with the bathroom heat exchanger 11 and the hot-water heater 12 of connecting.Bathroom heat exchanger 11 is arranged to the surface cooling heat exchanger structure.Hot-water heater 12 can adopt various cold-producing mediums and ability of swimming heat exchangers such as shell-tube type, shell coiled, bushing type, shell helix tube type.The refrigerant pipe of its heat exchanger 11 and hot-water heater 12 is connected to and constitutes bathroom heating and water heating and cooling agent closed circuit on the cold-producing medium circulation pipe of heat pump air conditioner, and as accompanying drawing, this closed circuit branch is set as winter and two loops of summer operation.The refrigerant pipe of bathroom of the present utility model heat exchanger 11 is connected to and constitutes heat exchanger heating and refrigeration agent loop, bathroom on the cold-producing medium circulation pipe of heat pump air conditioner.
Accompanying drawing 2 is heating of hot and cold water endless form and the refrigeration system that the output configuration of heat exchanger 4 is made up of water circulating pump 22 and air conditioner end equipment 23 with the difference of accompanying drawing 1.
The utility model winter, heating in summer and refrigeration air-conditioner operation conversion, through different circuit to hot-water heater 12 in the conversion of health hot water heating and bathroom heat exchanger 11 independent heating operations, finish by four-way change-over valve 2 and the valve 13,14,15,16,17,18,19,20 and 21 that is disposed at respectively in each refrigerant loop.
1 operation principle of the present utility model is described in conjunction with the accompanying drawings.
During winter operation, the high temperature refrigerant gas that compressor 1 is discharged is entered through conversion valve 13 by the dotted line path of four-way change-over valve 2 and carries out the health hot water heating through valve 21 to hot-water heater 12 again after bathroom heat exchanger 11 carries out the bathroom heating, condensed refrigerant liquid process conversion valve 14 is to expansion valve 3 throttlings, heat exchange coil 8 to outdoor heat exchanger 5, cold-producing medium after evaporation absorbs airborne low-temperature heat quantity to become gas by conversion valve 15 to another dotted line path of four-way change-over valve 2 to compressor 1 suction end, repeated above-mentioned compression cycle after being sucked by compressor.When water temperature reached design temperature in the hot-water heater 12, conversion valve 16 was opened refrigerant gas is entered indoor heat exchanger 4 to indoor heating heating, closed through time-delay late gate 13 and 21.Conversion valve 13 and 16 and 21 alternately opening and closing realize health hot water heating and indoor heating hocketing on request.When the compressor 1 that disposes is enough big, also can open conversion valve 13 and 16 simultaneously, heat hot water and heating are carried out simultaneously.After valve 16 was opened, Open valve 17 and 18 can import bathroom heat exchanger 11 with a part of high temperature refrigerant gas through its loop, and bathroom heating proceeds when guaranteeing that hot-water heater 12 stops to heat.
During summer operation, 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 conversion valve 19, carry out the health hot water heating through bathroom heat exchanger 11 to valve 21 through hot-water heater 12, condensed liquid refrigerant absorbs to indoor heat exchanger 4 evaporation after valve 20 is by expansion valve 3 throttlings that heat freezes to blows cold wind indoors in the air, evaporation becomes the cold-producing medium of gaseous state and gets back to compressor 1 through valve 16 to another solid line path of four-way change-over valve 2, continues to repeat above-mentioned compression cycle after being sucked by compressor.When the water temperature in the hot-water heater 12 reaches the temperature of setting, valve 15 is opened, close through time-delay valve 19, high temperature refrigerant is after valve 15 to the non-spray coil section of outdoor heat exchanger 5 is lowered the temperature earlier, enter spray coil 8 again and carry out the cooling of water spray, its liquid refrigerant to indoor heat exchanger 4 evaporation absorption room air heats, freezes to blows cold wind indoors after expansion valve 3 throttlings.
The indoor heat exchanger 4 of the utility model accompanying drawing 1 embodiment can dispose many, forms many formulas of holder air-conditioner.Heat exchanger 4 among accompanying drawing 2 embodiment is cold-producing medium ability of swimming all kinds heat exchangers, and the air conditioner end equipment of its secondary water system can be hot and cold ability of swimming fan coil formula air-conditioning equipment.
