As mentioned above, air regulator of the present invention is to connect a plurality of indoor sets 200 on an off-premises station 100, moves a part or all indoor sets 200 according to user's selection.If air regulator turns round under refrigeration mode, outdoor magnetic valve 102 is opened, and refrigerant flows between off-premises station 100 and indoor set 200.At first, the refrigerant that 100 li of off-premises stations are described flows: the gas that flows into from indoor set 200 flows into 132 li of fluid reservoirs through cross valve 124.The gas coolant that comes out from fluid reservoir 132 flows in the compressor 120,120 '.When supplying with compressor 120,120 ' cold medium shortage or compressor 120,120 ' overheated the time, supply with refrigerant from coolant injection device 120a.Compressor 120,120 ' compression refrigerant are discharged from outlet, and by oil eliminator 122.And refrigerant is fuel-displaced in 122 li separation of oil eliminator, and lubricating oil is recovered in the compressor 120,120 ' by oil return pipe 123.Oil is blended in the refrigerant in compressor 120,120 ' compression refrigerant process, but such oil is liquid condition and refrigerant is a gaseous state, so be 122 li each self-separations of oil eliminator at gas-liquid separator.
Compressor 120,120 ' inner lubricating oil in both sides is kept equilibrium by the oil equalizing pipe 121 that connects constant speed compressor 120 and frequency-changeable compressor 120 '.Refrigerant by oil eliminator 122 passes through 180 li of cross valve 124 inflow outdoor heat exchangers.Outdoor heat converter 180 plays condenser (during refrigeration mode) effect, so refrigerant is by carrying out heat exchange with extraneous air, be cooled into being liquid coolant.Refrigerant by outdoor heat converter 180 further cools off through supercooling machine 130 time.After the drying machine 131 through moisture in the refrigerant removal refrigerant of supercooling machine 130, flow into 200 li of indoor sets by the general pipe 210 of liquid.In compressor 120,120 ' the refrigerant, a part flows into 100 li of another off-premises stations by the general pipe 214 of high-low pressure.
180 li of off-premises station 100 outdoor heat converters that the refrigerant inflow of supplying with to another off-premises station 100 by the general pipe 214 of high-low pressure shuts down, make refrigerant pressure reach balanced on the whole, the outdoor heat converter 180 by the off-premises station 100 that shuts down also can carry out certain heat exchange simultaneously.Supply with refrigerant by the general pipe 210 of liquid to indoor set 200, refrigerant flows into 200 li of each central indoor sets of running by the liquid branch pipe 210 ' that comes out from the general pipe of liquid 210 branches.Such refrigerant carries out heat exchange for 202 li in expansion valve 204 decompressions and at indoor heat converter.At this moment, indoor heat converter 202 plays a part evaporimeter, so refrigerant is converted to low-pressure gas by heat exchange.Assemble at the general pipe 212 of gas through gas branch pipe 212 ' from the refrigerant that indoor heat converter 202 is discharged, flow into 100 li of off-premises stations then.By general pipe 212 of gas and outdoor flue 212 " refrigerant that flows into off-premises station 100 enters into 132 li of fluid reservoirs through cross valve 124.Filter at the be not able to do in time refrigerant of evaporated liquid state of 132 li of fluid reservoirs, have only the refrigerant of gaseous state to separate and supply to compressor 120,120 '.Thus, the course of work is finished a circulation.In the time of the running of air regulator heating mode, refrigerant flows to foregoing opposite direction, regulates coolant quantity in outdoor magnetic valve 102.
13 illustrate that the air of 100 li of off-premises stations flows with reference to the accompanying drawings.Power turn-on, fan electromotor 172 drives rotation blowing fan 170.If blowing fan 170 rotations, air outside flows into inner by front grid 114 and back grid 190.The inflow air of off-premises station 100 inside carries out heat exchange when passing through outdoor heat converter 180.At this moment, if the air regulator cooling operation, air outside is accepted heat from outdoor heat converter 180 and is become high temperature air, if opposite air regulator heats running, air outside is transmitted heat to outdoor heat converter 180 and become Cryogenic air.Air by outdoor heat converter 180 is by blowing fan 170 forced air supply upward.At this moment, ring cover 164 guiding air are discharged air upward.After radiator fan 148 sucks air, discharge upward, promote radiating part 146 ' heat exchange, heater element plate 146 is cooled.After the air of forced air supply passes through the air guide holes 152 of dividing plate 150 upward from radiator fan 148,, forwards discharge by 154 guiding of air pilot cap.The air of forwards discharging by air pilot cap 154 carries out heat exchange through front heat exchanger 182 time, discharges upward by ring cover 164.The scope of the invention does not limit in the above-described embodiment, and those of ordinary skill in the art can produce the various deformation based on the present invention within the scope of the claims.
As mentioned above, in the off-premises station of an one dragging more air conditioner of the present invention, be the center with the demarcation strip, at upside installation room outer heat-exchanger and at downside control box is installed.The various parts of control box inside can not be subjected to the influence of outdoor heat converter, can prevent the running of air regulator mistake thus.Be provided with radiating part and radiator fan in the back of control box, more effectively cooling is built in parts in the control box, can prevent the parts Yin Gaowen of control box inside thus and wrong running.Because each control assembly is normally brought into play the function of self, so the effect that can prevent in advance that the air regulator performance from descending is arranged.
