Describe the effect of one one dragging more ceiling air conditioner of the present invention in detail with reference to Fig. 7 to Figure 12, as follows:
Air-conditioner according to the present invention is that an off-premises station 100 connects a plurality of indoor sets 200, and starts the indoor set 200 of part or all because of user's selection.
If start air-conditioner (cooling operation), thereby refrigerant is flowed between off-premises station 100 and indoor set 200 with regard to open chamber mistress exoelectron valve 102.
At first, have a look flowing of refrigerant in the off-premises station 100, the gas coolant that flows into from indoor set 200 is to enter accumulator 132 through behind the cross valve 124.From accumulator 132 effluent air refrigerants flow into compressor 120,120 '.Also have compressor 120,120 ' or compressor 120,120 ' overheated occurs and supply with refrigerant by coolant injection device 120a because of the cold medium shortage supplied with.
By the refrigerant of compressor 120,120 ' compressed is to spue and through oil eliminator 122 to discharge opening.Oil eliminator 122 separate the oil that is contained among the refrigerant and by oily recovery tube 123 be recovered to compressor 120,120 '.
That is, oil is entrained in the refrigerant, and oil is that to be liquid, refrigerant be to be the gas shape, so in the oil eliminator 122 that plays the gas-liquid separator effect, separate because of compressor 120,120 ' compression refrigerant.
By connect constant speed compressor 120 and frequency-changeable compressor 120 ' oil equalizing pipe 121 and make the oil of both sides compressor 120,120 ' inside keep equilibrium.
Refrigerant by oil eliminator 122 is to flow into outdoor heat converter 180 through cross valve 124.Because of outdoor heat converter 180 has been condenser effect (during refrigeration modes), so refrigerant is to obtain cooling and become liquid coolant by carrying out heat exchange with extraneous air.Refrigerant by outdoor heat converter 180 is more can obtain cooling through supercooling machine 130.
Refrigerant through supercooling machine 130 is to remove the drier 131 that comprises water function in the refrigerant through playing earlier, flows into indoor set 200 by common liquid pipe 210 then.Through compressor 120,120 ' refrigerant 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 refrigerants that supply to other off-premises station 100 is when flowing into the outdoor heat converter 180 of the off-premises station 100 in stopping and balanced on the whole refrigerant pressure, the heat exchange that also can make it to produce regulation by the outdoor heat converter 180 of the off-premises station in stopping 100.
If refrigerant 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 ' refrigerant is supplied to each indoor set 200 that is starting.Refrigerant is to obtain decompression and realize heat exchange at indoor heat converter 202 in expansion valve 204.Indoor heat converter 202 has been effects of evaporimeter, so refrigerant is to become low-pressure gas by heat exchange.
The refrigerant 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." refrigerant that flow into off-premises station 100 is to enter accumulator 132 through cross valve 124 by common tracheae 212 and outdoor tracheae 212.
In accumulator 132, filter in time not evaporate and be liquid refrigerant and stay in the accumulator 132, only allow gasiform refrigerant supply to compressor 120,120 '.Finish a circulation by process like this.
Also have, with the mobile refrigerant of rightabout, and in outdoor electronic valve 102, regulate coolant quantity when starting warming operation.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 transmit and be heated and become high temperature air from outdoor heat converter 180, is absorbed heat and becomes Cryogenic air by heat exchanger 180 when heating operation on the contrary.
Through the air of outdoor heat converter 180 is by blowing fan 170 forced air supply upward, and this moment, ring cover 164 was that the top of guiding air spues.
This type of scope of invention is to be not limited to present embodiment, and for the operator of the same industry, it is possible can carrying out many distortion based on the present invention within the present technique scope.
