Followingly the control procedure of preferred embodiment of the present invention air-conditioner when being activated at first described with reference to Fig. 3.
At first, select refrigeration processes or heating process.Then, at operating procedure S10, controller 22 drive compression machine drivers 12.Meanwhile, controller 22 control cooling water valves 15 make cooling water pass through cooling water valve 15, along outdoor heat exchange circulating path circulation, flow to cooling water radiator 4, and keep expansion valve 7 to close.And then at operating procedure S11, controller 22 controls are closed driving force and are added to/cut off parts 13, make the driving force from compressor drive 12 not be transmitted to compressor 6.Thereby, avoid cold-producing medium inflow compressor 6 when air-conditioner is activated at first, at first to prevent to flow into the inflow of the liquid refrigerant that is comprised in the cold-producing medium of compressor 6.
Meanwhile, temperature sensor 20 detects the temperature by the cooling water of compressor drive 22 heating, and at operating procedure S12, controller 22 determines whether the temperature that temperature sensors 20 record surpasses predetermined temperature.
Then, if the cooling water temperature that temperature sensor 20 records surpasses predetermined temperature, then at operating procedure S13, controller 22 control cooling water valves 15 make cooling water flow to cold-producing medium heater 11 by cooling water valve 15 along cold-producing medium heat cycles path.So, flow to the cold-producing medium of the heated cooling water heating of cooling water heater 11 by cold-producing medium heater 11, so that the liquid refrigerant that can remove in the cold-producing medium to be comprised.
If the cooling water temperature that temperature sensor 20 records surpasses predetermined temperature, then at operating procedure S14, controller 22 controls are opened driving force and are added to/cut off parts 13, and the driving force from compressor drive 12 is sent to compressor 6, thus drive compression machine 6.As shown in Figure 4, minimum for the inflow that makes liquid refrigerant, can after the scheduled time when cooling water valve 15 is controlled compressor 6 be driven.The driving time of Fig. 4 (a) expression compressor drive 12, the driving time of Fig. 4 (b) expression compressor 6, the driving time of Fig. 4 (c) expression cooling water valve 15.B among Fig. 4 (c) represents that heated cooling water flows to the zone of cold-producing medium heater 11 along cold-producing medium heat cycles path, and the A among Fig. 4 (c) represents that heated cooling water flows to the zone of outdoor heat exchange section 2 along outdoor heat exchange circulating path.In other words, Fig. 4 (c) is illustrated in the air-conditioner when being driven at first during the refrigeration processes.So if air-conditioner is in the heating process, then regional A keeps the situation the same with the area B of Fig. 4.
If the cooling water temperature that temperature sensor 20 records surpasses predetermined temperature, then controller 22 is opened expansion valve 7, makes cold-producing medium flow into compressor 6.
Then, at operating procedure S16, controller determines whether the refrigerant superheat degree that is recorded by overheat detector 21 surpasses predetermined degree of superheat.If the described degree of superheat that overheat detector 21 records surpasses predetermined degree of superheat, then at operating procedure S17, controller 22 normal running cooling water valves 15.In other words, have as described above, according to controller 22 heating processes or refrigeration processes control cooling water valve 15.
In the above-described embodiments, the temperature that temperature sensor 20 records when being activated at first according to compressor drive 12, controller 22 control cooling water valves 15 and driving force add to/cut off parts 13, but are not limited thereto.Can make cooling water valve 15 and driving force add to/cut off parts 13 and be opened after the scheduled time when compressor drive 12 is activated at first.
Similarly, the invention provides a kind of air-conditioner, comprising: driving force adds to/cuts off parts 13, in order to future driving force add to compressor 6 from compressor drive 12, perhaps cut off the driving force that adds to compressor 6 from compressor drive 12; Cooling water pipe 23, cooling water is circulation in pipe, with cooling compressor driver 12, and forms cold-producing medium heat cycles path therein, so that by the cooling water heating of cooling compressor driver 12 mobile cold-producing medium in compressor 6; Be located at the cold-producing medium heater 11 on the cold-producing medium heat cycles path of cooling water pipe 23, so that the cold-producing medium that in compressor, flows by the cooling water heating of cooling compressor driver 12; Cooling water valve 15, in order to opening/closing the cooling water of cooling compressor driver 12 along the circulation in cold-producing medium heat cycles path; And controller 22, in order to when compressor drive 12 is activated at first, add in driving force/cut off under parts 13 and the cooling water valve 15 pent situations, after the scheduled time after controller 22 drive compression machine drivers 12, open driving force and add to/cut off parts 13 and cooling water valve 15.So, in initial drive pattern, can make the liquid refrigerant of air-conditioner of the present invention flow into minimum.
In addition, hydraulic accumulator 9 can not be jumbo, so that when compressor 6 is received driving at first, prevents that liquid refrigerant from flowing into compressor, thereby reduces cost of manufacture.
As mentioned above, the invention provides a kind of air-conditioner, it reduces cost of manufacture, and the inflow of liquid refrigerant is minimum when compressor is activated at first.
