At first, flowing of cold-producing medium in the off-premises station 100 is described, the gas refrigerant that flows into from indoor set 200 is to enter accumulator 132 through behind the cross valve 124.From accumulator 132 effluent air cold-producing mediums flow into compressor 120,120 '.When also having compressor 120,120 ' or compressor 120,120 ' overheated occurring, by refrigerant injection device 120a the supply system cryogen because of the lack of refrigerant supplied with.
By compressor 120,120 ' refrigerant compressed is to discharge and process oil eliminator 122 to outlet.In oil eliminator 122, separate the oil be contained among the cold-producing medium, and by oily recovery tube 123 be recovered to compressor 120,120 '.
That is, because of compressor 120,120 ' compressed refrigerant oil is entrained in the cold-producing medium, and such oil is to be liquid, cold-producing medium is to be the gas shape, so be to separate in the oil eliminator 122 at gas-liquid separator.
Also have, by connect constant speed compressor 120 and frequency-changeable compressor 120 ' oil equalizing pipe and make the oil of both sides compressor 120,120 ' inside keep equilibrium.
Cold-producing medium by oil eliminator 122 is to flow into outdoor heat converter 180 through cross valve 124.Because of outdoor heat converter 180 is to act on condenser (during refrigeration modes), so cold-producing medium is to obtain cooling and become liquid refrigerant by carrying out heat exchange with extraneous air.Cold-producing medium by outdoor heat converter 180 is more can obtain cooling through supercooling machine 130.
Cold-producing medium through supercooling machine 130 is to remove the drying machine 131 that comprises water function in the cold-producing medium through playing earlier, flows into indoor set 200 by common liquid pipe 210 then.Also have, through compressor 120,120 ' cold-producing medium in a part be to flow into another one off-premises stations 100 by the common pipe 214 of high-low pressure.
By the common pipe of high-low pressure 214 cold-producing mediums that supply to other off-premises station 100 is to flow in the outdoor heat converter 180 of the off-premises station 100 in being stopped, and balanced on the whole refrigerant pressure the time, the also heat exchange that can produce regulation by the outdoor heat converter 180 of the off-premises station in being stopped 100.
If cold-producing medium supplies to indoor set 200 by common liquid pipe 210, just can be by by branch's liquid pipe 210 of common liquid pipe 210 branches ' cold-producing medium is supplied to each indoor set 200 that is starting.Also have, such cold-producing medium is to obtain decompression and realize heat exchange at indoor heat converter 202 in expansion valve 204.At this moment, indoor heat converter 202 has been effects of evaporimeter, so cold-producing medium is to become low-pressure gas by heat exchange.
The cold-producing medium of discharging from indoor heat converter 202 is through dividing a bronchus 212 ' accumulate in common tracheae 212, flowing into off-premises station 100 then." cold-producing medium that flow into off-premises station 100 is to enter 132 li of accumulators through cross valve 124 by common tracheae 212 and outdoor tracheae 212.
In accumulator 132, filter and in time do not evaporate and be liquid cold-producing medium, and only allow gasiform cold-producing medium select to supply to compressor 120,120 '.Finish a circulation by process like this.
Also have, when starting warming operation and above-mentioned rightabout flow system cryogen, and in outdoor electronics valve 102, regulate refrigerant amount.
Then, have a look flowing of air in the off-premises station 100, thereby start blowing fans 170 because of importing power supply fan motor 172.Blowing fan 170 rotations can make extraneous air pass through front grid 114 and back grid 190 and flow into inner.
The air that flow into off-premises station 100 inside is through outdoor heat converter 180 and carries out heat exchange.At this moment, air-conditioner extraneous air when freezing operation is to accept heat and become high temperature air from outdoor heat converter 180, when carrying out warming operation, is absorbed heat and becomes Cryogenic air by heat exchanger on the contrary.
Through the air of outdoor heat converter 180 is by blowing fan forced air supply upward, and this moment, the ring cover 164 was that the guiding air is discharged upward.
This type of scope of invention is to be not limited to above-mentioned illustrative embodiments, for the common operator when industry, is possible based on a lot of distortion beyond of the present invention within as above-mentioned technical scope.
