Wherein electromagnetism two- port valve 5,6 is all closed type; O represents opening; X represents closed condition.
As shown in Figure 1, the path of refrigerant is all identical in " cold air+hot water ", " dehumidifying+hot water " two kinds of circulations, but when dehumidifying, low excessively for avoiding indoor temperature, running is given in just shut-down operation after running dehumidifying a period of time after a while again.Refrigerant promotes its outlet refrigerant enthalpy via compressor 1 compression in above-mentioned circulation becomes superheated vapor, make hot water through hot water exchanger 2 then, remaining heat liquefies refrigerant by condenser 3 dischargings that are connected on thereafter fully, again enter indoor evaporator 7 with the low-pressure liquid refrigerant through two-port valve 6 via expansion gear 4 backs again and absorb heat into the low pressure gaseous coolant, enter compressor 1 again through cubic valve 11 again and promptly finish a circulation, this moment, the electromagnetism two-port valve 5 cut out, the refrigerant outdoor evaporimeter 9 of not flowing through.
As shown in Figure 2, in " heating installation+hot water " circulation, topmost function is that the outer heat of suction chamber is to indoor discharging, to promote indoor temperature, so flow through hot water heat exchanger 2 after the effect of cubic valve 11 at refrigerant, make the path switch to indoor evaporator 7, this moment, evaporimeter 7 was when the condenser use, the heat of discharging high-pressure gaseous refrigerant when refrigerant becomes high-pressure liquid, enters expansion gear 4 via electromagnetism two-port valve 6 again and makes refrigerant become low-pressure liquid, enter condenser 3 then, condenser 3 is gasified totally refrigerant when evaporimeter uses at this moment, enters compressor 1 again.Two-port valve 5 does not use outdoor evaporimeter still for cutting out at this moment.
As shown in Figure 3, " in the circulation of hot water individual operation (this is an emphasis of the present utility model); this circulates in the outdoor one group of outdoor evaporimeter 9 that added in addition; its circulating path is the hyperthermia and superheating steam after refrigerant compresses via compressor 1; make hot water through hot water heat exchanger 2 earlier, and remaining heat is still by condenser 3 dischargings, and after refrigerant liquefies fully; through expansion gear 4 and two-port valve 5, outer evaporimeter 9 draw heats of inlet chamber return compressor.This moment, the electromagnetism two-port valve 6, and indoor fan 8 and cubic valve 11 also are failure to actuate, and also referred to indoor evaporator not effect 7 this moments.
Above-mentioned outdoor evaporimeter 9 coexists with condenser 3 in the space, and with wind direction, condenser 3 is before outdoor evaporimeter 9, and this ranking method is to wish that the heat that condenser 3 is discharged can be absorbed by outdoor evaporimeter 9.
When hot water heat exchanger's 2 heat-obtainings for a long time, relative condenser 3 heat dissipation capacities are few, outdoor evaporimeter 9 can be drawn outer gas heat (because of evaporator refrigerant temperature is lower than outside air temperature), again when the hot water temperature is high, hot water reduces with the end refrigerant temperature difference that spues, reduce hot biography amount, hot water heat exchanger's 2 heat-obtainings are few, heating water cop value (energy efficiency) descends, condenser 3 heat dissipation capacities increase thereupon, to feasiblely increase through the air enthalpy behind the condenser 3, that is the air themperature rising of the outer evaporimeter 9 of inlet chamber, because of air themperature and the increasing of the evaporator refrigerant temperature temperature difference, to make outdoor evaporimeter 9 caloric receptivities increase, also make compressor 1 suction side refrigerant enthalpy increase, and then compressor outlet refrigerant enthalpy is increased, because of the superheated vapor enthalpy increases, must cause refrigerant temperature to rise, just can strengthen the temperature difference of refrigerant and water, increase the heat biography amount of refrigerant and water, make hot water cop value maintain a higher level.
In addition, when outside air temperature was low, hot water running separately, but the heat that outdoor evaporimeter 9 absorptive condensers 3 are discharged avoided that condenser 3(uses as evaporimeter this moment when turn round as greenhouse) the phenomenon generation of freezing.
See also each accompanying drawing, the utility model includes cold medium compressor 1 when implementing, and the hot water heat exchanger 2, condenser 3, expansion gear 4, two- port valve 5,6, indoor evaporator 7, indoor fan 8, outdoor evaporimeter 9, outdoor fan 10, members such as cubic valve 11 and temp control switch 12.
When reaching " dehumidifying+hot water " as " cold air+hot water ", the utility model sees also Fig. 1 when recycling, two-port valve 5 and cubic valve 11 are closed (Fig. 1 dotted line for idle path) and are opened two-port valve 6 and indoor interior wing 8(Fig. 1 solid-line paths is a cooling air circulation system), its operation is that refrigerant makes its outlet refrigerant enthalpy lifting becoming superheated vapor via compressor 1 compression earlier, the hot high pressure refrigerant disengages heat through hot water heat exchanger 2, to make hot water, its remaining heat is discharged heat radiation by the condenser 3 that is connected on thereafter again, make the refrigerant cooling, liquefaction fully, again via expansion gear 4 releases of pressure, enter indoor evaporator 7 through two-port valve 6 again with the low-pressure liquid refrigerant and absorb heat into the low pressure gaseous coolant, and the running of the borrowing indoor fan 8 cold air conditioner operation that carries out, this low pressure gaseous coolant enters compressor 1 through cubic valve 11 again and promptly finishes a circulating cold air at last.This moment, two-port valve 5 cut out, the refrigerant outdoor evaporimeter 9 of not flowing through.The running of dehumidifying+hot water and cold air+hot water, all identical on circulating path, just when dehumidifying, low excessively for avoiding indoor temperature, just shut-down operation after running dehumidifying a period of time must be given running after a while again.
When the utility model as " heating installation+hot water " when recycling, see also Fig. 2, two-port valve 5 cuts out (Fig. 2 dotted line is idle path) and opens two-port valve 6, indoor fan 8 and cubic valve 11; Its operation be refrigerant flow through earlier behind the hot water heat exchanger 2 promptly to switch via cubic valve 11 flow to indoor evaporator 7(and be used as condenser at this moment and use) in order to the heat of discharging high-pressure gaseous refrigerant (and the running of borrowing indoor fan 8 carry out heating air conditioner operation), after refrigerant becomes high-pressure liquid, entering expansion gear 4 through two-port valve 6 again makes refrigerant become low-pressure liquid, enter condenser 3(then and be used as the evaporimeter use at this moment), refrigerant is gasified totally, enters compressor 1 at last again.Two-port valve 5 in this circulation this moment cuts out, and does not use outdoor evaporimeter 9.
When the utility model sees also Fig. 3 during as hot water circuit, two-port valve 6, indoor fan 8 and cubic valve 11 are closed (Fig. 3 dotted line is idle path) and are opened two-port valve 5, its operation is that the hyperthermia and superheating steam (hot refrigerant) after refrigerant compresses via compressor 1 is made hot water through hot water heat exchanger 2 earlier, remaining heat is still discharged by condenser 3, after refrigerant liquefies fully, through expansion gear 4, two-port valve 5, the outer evaporimeter 9 of inlet chamber then, with the outer atmosphere heat of suction chamber, return compressor 1 and finish the independent operation of hot water.
In addition, in the hot water individual operation when outside air temperature is low, but the heat that outdoor evaporimeter 9 draw in cold condensers 3 are discharged, low excessively because of outside air temperature when avoiding turn round as greenhouse, condenser 3(be evaporimeter at this moment) the icing phenomenon of the not enough generation of heat absorption.And temp control switch 12 is used for controlling and adjusting the hot water temperature of hot water storgae, and is too high or too low to prevent the water temperature, and it is remained among certain available water temperature range.
In sum, owing to added evaporimeter 9, make to the utlity model has cold air, heating installation, dehumidifying and the multiple function of hot water also can improve the cop value (energy efficiency) of hot water, significantly promote the add thermal effect of hot refrigerant to water, promote the effect of efficiency of energy utilization and recovery used heat, and when not using air-conditioning, still have the hot water supply, promote the service efficiency of air-conditioning equipment, increasing economic efficiency, is one to conform with the design of practicality and dark tool economic worth.
