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 ' 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, also can carry out certain heat exchange by off-premises station 100 outdoor heat converters 180 that shut down simultaneously.If the general pipe 210 of the liquid that passes through is supplied with refrigerant 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.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." refrigerant that flows into off-premises station 100 enters into 132 li of fluid reservoirs through cross valve 124 by general pipe 212 of gas and outdoor flue 212.At fluid reservoir 132, the refrigerant of the evaporated liquid that is not able to do in time state filters, and has only the refrigerant of gaseous state to separate and supplies to compressor 120,120 '.Thus, finish a circulation through said process.In addition, when the air regulator heating mode turned round, refrigerant flowed to foregoing opposite direction, regulates coolant quantity in outdoor magnetic valve 102.
The air that the following describes 100 li of off-premises stations flows.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.Left side control box 140 utilizes hinge 140a to be connected on the left forward side support 134, so if forwards draw right-hand end, left side control box 140 is that forwards rotate in the axle center with the left-hand end.Right side control box 140 ' utilize hinge 140 ' a be connected right forward side support 134 ' on, so if forwards draw left-hand end, right side control box 140 ' with the right-hand end is that forwards rotate in the axle center.
The scope of the invention does not limit in the above-described embodiment, and those skilled in the art can produce the various deformation based on the present invention in the scope of 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.Therefore, 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.In addition,, carry out after in the time will carrying out operation such as after-sale service, can forwards rotating control box, improved operating efficiency because control box utilizes hinge to be installed in rotation on the place ahead support.
