The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1; A kind of air-conditioning system of the utility model; Comprise compressor 10, indoor heat exchanger 1, outdoor heat exchanger 5, capillary 6, cross valve 4, first valve port of cross valve 4 connects the exhaust outlet of compressor 10, and second valve port connects indoor heat exchanger 1; The 3rd valve port connects compressor 10 return line, the 4th valve port junction chamber external heat exchanger 5.Also comprise assisted capillary 13 and check valve 7 in the refrigeration system, assisted capillary 13 is connected capillary 6 with check valve 7 and after connecing.On indoor heat exchanger 1 and outdoor heat exchanger 5, be respectively equipped with indoor and outdoor fan operation (not shown), wherein (among the figure, the indoor is represented on the dotted line left side in the outside for compressor 10, outdoor heat exchanger 5, capillary 6, cross valve 4; Expression outside, dotted line the right); On tube connector, be provided with first magnetic valve 3 and second magnetic valve 8 at indoor heat exchanger 1; Between the indoor heat exchanger 1 and second magnetic valve 8, be provided with and discharge magnetic valve 9, a side that discharges magnetic valve 9 is communicated with outdoor environment, first magnetic valve 3, second magnetic valve 8, release magnetic valve 9; On the pipeline of outside, on indoor heat exchanger 1, also be provided with concentration inductor 12.
The refrigeration work process of the air-conditioning system of the utility model is such: when the air-conditioner refrigerating operaton; Flow to outdoor heat exchanger 5 through the high-temperature high-pressure refrigerant of compressor 10 compression first valve port and the 4th valve port through cross valve 4; The condensation cooling becomes the cryogenic high pressure cold-producing medium in outdoor heat exchanger 5; After capillary 6 throttling step-downs; Flow to indoor heat exchanger 1 from check valve 7, second magnetic valve 8, the heat absorption evaporation becomes the cold-producing medium of high-temperature low-pressure in indoor heat exchanger 1, gets back to compressor 10 through first magnetic valve 3 with cross valve second valve port, the 3rd valve port.
Because the air-conditioning system of the utility model adopts flammable coolants such as R290, therefore,, be provided with unique shutdown control subprogram on the shutdown control program of the utility model in order to ensure indoor heating system safety, shutdown back cold-producing medium is withdrawn in the off-premises station.As shown in Figure 3; Under refrigeration mode, when air-conditioning system received shutdown command, carry out the shutdown subprogram of refrigeration mode: the power supply that controller cuts off second magnetic valve 8 made its closure; Stop cold-producing medium to continue to flow to indoor heat exchanger 1; This moment, compressor 10 also moved, the indoor and outdoor fan operation, and the electricity that postpones T1 second (T1=20S) back cut-out first magnetic valve 3 makes its closure; While close compressor 10 and indoor and outdoor blower fan, thus guaranteed that whole refrigerant-recovery are to the outside when air-conditioning does not move.
Under the refrigeration work pattern, first magnetic valve 3, second magnetic valve 8 are opened, and cold-producing medium can flow through this two magnetic valves, discharge magnetic valve 9 and then are in the power-failure close state.If the R290 leakage takes place indoor set when refrigerating operaton, the concentration inductor 12 on the indoor heat exchanger 1 can detect the change in concentration of airborne R290 at once, and is as shown in Figure 5; When concentration met or exceeded setting value A, system was judged to be R290 and leaks, buzzer action this moment; Give the alarm; And cutting off first magnetic valve 3 and 8 power supplies of second magnetic valve simultaneously, two solenoid closures make most cold-producing medium be isolated in the outside.At this moment, the indoor and outdoor blower fan of air-conditioning system is forced to run up, and compressor 10 cuts out.The R290 that accumulate the indoor can be discharged to outdoor through release magnetic valve 9, and running up of indoor and outdoor blower fan reduces the concentration of cold-producing medium, avoids dangerous generation.When the concentration inductor detects the airborne R290 concentration in indoor less than setting value B up to the indoor (A is more than or equal to B), system closing indoor and outdoor blower fan cuts out buzzer, discharges magnetic valve 9 closures.Air-conditioning system also can time-delay detect R290 concentration in 1 minute again after leaking the control program startup; R290 concentration just finishes to leak control program less than setting value B when the indoor; Otherwise; Buzzer gives the alarm always, and the indoor and outdoor blower fan continues to run up, and first magnetic valve 3 and second magnetic valve 8, compressor 10 keep shut.
As shown in Figure 2; When air-conditioner operation heating mode; Its course of work is: the high-temperature high-pressure refrigerant that comes out from compressor 10 is after first valve port, the 4th valve port stream and first magnetic valve 3 of cross valve 4 flows to indoor heat exchanger 1 and room air exchange heat; The cold-producing medium of cryogenic high pressure flows to outdoor heat exchanger 5 after second magnetic valve 8, assisted capillary 13 and capillary 6 throttlings, second valve and the 3rd valve port through cross valve 4 flows back to compressor 10 again.This moment first, magnetic valve 3, second magnetic valve 8 were opened, and cold-producing medium can flow through this two magnetic valves, and release magnetic valve 9 then is in the power-failure close state.
Shown in Figure 4 is the program at the normal shutdown of the air-conditioning system with cold and hot translation function: after receiving off signal, controller is judged the pattern of operation of air conditioner through the power supply state that detects cross valve 4, and carries out different programs.If cross valve 4 outages are then carried out refrigeration mode ShiShimonoseki loom program (as shown in Figure 3), if cross valve 4 is "on" positions; Promptly carry out heating mode before the shutdown, then receive shutdown command after, 4 outages of control cross valve; And compressor 10 operations, indoor and outdoor blower fan are left, time-delay T2 second (T2=5S) back second magnetic valve, 8 power-failure closes are behind T1 second (20S) that delays time again; First magnetic valve, 3 power-failure closes, close compressor 10 and indoor and outdoor blower fan simultaneously.Like this, when the air-conditioner no power moved, R290 can be recycled to the outside, thereby had guaranteed the safety of indoor.
As shown in Figure 6, when heating operation, leak if R290 takes place in the indoor; Indoor R290 concentration inductor 12 can detect the change in concentration of R290 in the air at once, when concentration reaches or during greater than setting value A, air-conditioning system is judged as R290 and leaks; If this moment cross valve 4 no powers then carry out the leakage control program (as shown in Figure 5) of refrigeration mode, if cross valve 4 electric, promptly air-conditioning system is carried out heating mode; Rapid continuous short song is sent in then buzzer work, and cuts off the power supply of second magnetic valve 8 at once; Make its closure, this moment, the indoor and outdoor blower fan was forced high-speed cruising, simultaneously close compressor 10 and cross valve 4.The refrigerant pressure of indoor is higher when heating; The cold-producing medium of outside is a low pressure; So most refrigerant is all in the indoor, therefore, air-conditioning system postpones 5s makes the high pressure refrigerant of indoor flow to the outside of low pressure; And then the power supply that cuts off first magnetic valve 3 makes its closure, discharges magnetic valve 9 energisings simultaneously and opens.The R290 of indoor is discharged to outdoor through discharging magnetic valve; Whether R290 concentration inductor 12 sensing chamber inboard air R290 concentration less than setting value B after postponing 1min, if be lower than setting value B then the inside and outside blower fan of close chamber cuts out buzzer; R290 discharges magnetic valve 9 power-failure closes; Otherwise the indoor and outdoor blower fan continues to force high wind operation, and R290 discharges magnetic valve 9 and continues energising, till the airborne R290 concentration in indoor is lower than setting value.
