At first, the flow process of the refrigerant in the off-premises station 100 is as follows: discharge after the compressed machine 120,120 of the gaseous coolant ' compression of off-premises station 200 inflows again.From the refrigerant of compressor 120,120 ' discharge by oil eliminator 122 the time, separate fuel-displaced after, be recovered to again compressor 120,120 '.Be refrigerant in the time of compressor 120,120 ' compression, oil can be mixed in together with refrigerant.At this moment, oil is liquid, and refrigerant is a gaseous state.So be separated for 122 li at oil eliminator as gas-liquid separator.
By the refrigerant of oil eliminator 122, behind cross valve 124, flow into outdoor heat converter 180.What at this moment, outdoor heat converter 180 play a part is condenser (in the time of refrigeration mode).So refrigerant and outdoor air carry out changing liquid refrigerants into after the heat exchange.By the refrigerant of outdoor heat converter 180, in the time of subcooler 130, cooled off again.
Through the refrigerant of subcooler 130, behind drier (not shown), flow into indoor set 200 through being total to fluid-through tube 210.By compressor 120,120 ' a part of refrigerant by the common pipe 214 of high-low pressure, flow into other off-premises station 100.
Supply to the refrigerant of other off-premises station 100 by the common pipe 214 of high-low pressure, flow into withdraw from service off-premises station 100, make the pressure of refrigerant obtain whole equilibrium.Simultaneously, by the outdoor heat converter of the off-premises station in stopping using 100, refrigerant also carries out some heat exchanges.
When refrigerant supplies to indoor set 200 by fluid-through tube 210 altogether, the branch's liquid pipe 210 by diverging to from fluid-through tube 210 altogether ', refrigerant is supplied to each indoor set 200 in the work.Refrigerant carries out heat exchange at indoor heat converter 202 after expansion valve 204 decompressions.At this moment, indoor heat converter 202 plays the effect of evaporimeter, so refrigerant is converted into low pressure gas after by heat exchange.
The refrigerant of discharging from indoor heat converter 200 by divide a bronchus 212 ' after, be collected in common tracheae 212.Then, flow into off-premises station 100.By common tracheae 212 and outdoor tracheae 212 " after flow into the refrigerant of off-premises station 100, flow into fluid reservoir 132 through cross valve 124.
After fluid reservoir 132 filters out still unevaporated liquid refrigerants, have only gaseous coolant supply to compressor 120,120 '.Finish a circulation by above-mentioned process.
In the work of heating, the flow direction of refrigerant is opposite with said process, and, on outdoor magnetic valve 102, adjust the amount of refrigerant.
Flow into the air of the inside of off-premises station 100, in the time of by outdoor heat converter 180, carry out heat exchange.At this moment, when air-conditioner carried out refrigeration work, air outside changed high temperature air into after outdoor heat converter 180 heat absorptions.On the contrary, when heating work, extraneous air loses heat at outdoor heat converter, thereby changes Cryogenic air into.
Air by outdoor heat converter 180 is forced to be sent to the top by blowing fan 170.At this moment, radiator 164 guiding air are discharged to the top.
In addition, in above-mentioned enforcement side, though be provided with two compressors 120,120 ', and only be to use a fluid reservoir 132.But two fluid reservoirs 132 are set, make it respectively be connected to compressor 120,120 ' also be possible.
