in power connection open-minded.The loop conducting of refrigerator refrigeration system 10, the beginning of refrigerator refrigeration.Because the utility model must not changed former refrigerator refrigeration system, so refrigerator refrigeration system 10 operation principles are omitted.Cold-producing medium in the refrigerator refrigeration system 10 roughly flow process is to discharge → flow through electromagnet cut off valve 13 → condenser 11 cooling → devices for drying and filtering 9 filtration → capillaries 8 throttlings → evaporimeter 6 from compressor 5 compressions and evaporate → be sucked into compressor 5 and compress once more.Circulation repeatedly.The duty of this moment is that refrigerator refrigeration system 10 is realized refrigeration, air-conditioning refrigeration system 17 break-ofves.Connect contactor 31, electromagnet cut off valve 4 and 15 is open-minded, and air-conditioning refrigeration system 17 is started working.Operation principle is: the high-temperature high-pressure overheat steam of discharging from compressor 5 flows through electromagnet cut off valve 15 and enters condenser 18 and carry out heat exchange with air, make superheated steam become saturated vapor gradually, and then become saturated liquid, the saturated liquid that flows out from condenser 18 filters after capillary 1 expenditure and pressure by device for drying and filtering 19, become the moist steam of low-temp low-pressure, enter evaporimeter 3 then, inhale and remove the air heat of evaporimeter 3 of flowing through, thereby realize cooling.The gas that flows out from evaporimeter 3 enters compressor 5 through electromagnet cut off valve 4 and compresses once more.So circulation repeatedly.The length of capillary 1 and internal diameter are decided on required evaporating temperature.The duty of this moment is: refrigerator, air-conditioning refrigeration system 10,17 all realize refrigeration, when the refrigerator refrigeration reaches temperature required, temperature-sensitive bag 7 sends signal and makes freezer temperature control device 12 cut off the circuit of compressors 5 automatically and electromagnet cut off valve 13 is cut off by, refrigerator refrigeration system 10 loops, and the refrigerator refrigeration stops.The duty of this moment is: refrigerator refrigeration system 10 stops refrigeration, air-conditioning refrigeration system 17 continues refrigeration, when the room temperature of required air-conditioned room drops to predetermined temperature, temperature-sensitive bag 2 sends signal, air-conditioning temperature controller 16 cuts off the circuit of compressor 5 automatically and makes electromagnet cut off valve 4,15 end, and air-conditioning refrigeration system 17 loops cut off, and air conditioner refrigerating stops.The duty of this moment is: refrigerator, air-conditioning refrigeration system 10,17 all stop refrigeration, when refrigerator cold-storage freezes temperature recovery when needing the temperature of refrigeration, the signal that temperature-sensitive bag 7 sends automatically makes 12 actions of freezer temperature control device connect compressor 5 and electromagnet cut off valve 13, refrigerator refrigeration system 10 loops reclose, and the refrigerator refrigeration is restarted.When room temperature went back up to the temperature that needs cooling, the signal that temperature-sensitive bag 2 sends automatically made the circuit of air-conditioning temperature controller 16 action connection electromagnet cut off valve 4 and 15 and open-minded, and air-conditioning refrigeration system 17 loops reclose, and air conditioner refrigerating begins.Refrigerator, air-conditioning temperature controller 12 and 16 parallel connections are after protector 14 connects the compressor electric motor circuit.As long as refrigerator, air-conditioning temperature controller 12 and 16 have a branch road path, compressor 5 circuit are promptly connected startup work.Have only refrigerator, air-conditioning temperature controller 12 and 16 all obstructed, the circuit of compressor 5 just is cut off, and quits work.Refrigerator, air-conditioning temperature controller 12 and 16 temperature-control range are looked the needs of the target of system separately and are set up.The temperature of air-conditioning temperature controller 16 is transferred high 1-3 ℃ in the comparable general air-conditioner of the upper limit, and this helps alleviating the live load of compressor, saves electric energy, has also more scientifically satisfied the requirement of ordinary consumer to air-conditioning simultaneously.Documents and materials and facts have proved generally are that 5 ℃ of degree of △ are advisable with the indoor/outdoor temperature-difference, otherwise the people knows from experience and is subjected to " heat wave impacts " and generation discomfort.Electromagnet cut off valve 4 and 15 constitutes a self-locking circuit.Open-minded simultaneously, end simultaneously, be controlled by air-conditioning
