The specific embodiment
The present invention such as Fig. 1 are shown in Fig. 2-a, Fig. 2-b, Fig. 2-c, Fig. 2-d.
Refrigerant circulation loop is unified into refrigeration cycle with air-conditioning duct with compressor of air conditioner, condenser, throttling expansion device, evaporimeter etc.,
The refrigerating medium closed circuit is unified into refrigerating medium loop with pipeline with cold-accumulating box, air heat exchanger, refrigerating medium heat exchanger, refrigerating medium control device, expansion tank etc.
Wherein the evaporimeter of kind of refrigeration cycle is incorporated in the refrigerating medium heat exchanger, realizes the transmission of cold from the cold-producing medium to the refrigerating medium.The refrigerating medium control device is made up of a series of control valves and coolant pump; Control valve can be adjusted the flow direction of refrigerating medium; Coolant pump can be adjusted the flow of refrigerating medium, and the refrigerating medium control device can be controlled the flow direction and the flow of refrigerating medium automatically according to the difference of mode of operation.In the cold-accumulating box, the low-temperature storage cold that refrigerating medium can be certain.Air heat exchanger places in the driver's cabin, is equipped with evaporation fan, is used to discharge the cold of refrigerating medium, to reach the purpose that reduces indoor temperature.Expansion tank is used for the pressure of balance refrigerating medium circulation, and the steam that produces when discharging the refrigerating medium periodic duty is to avoid corrosion and to influence heat exchange effect.
In the course of the work,
Shown in Fig. 2-a, direct refrigeration work pattern, refrigerant circulation loop operate as normal; (compression condensation-throttling expansion-evaporation-compression); In the refrigerating medium closed circuit, through the refrigerating medium control device, refrigerating medium only passes through air heat exchanger; The cold that evaporimeter discharged in the cold-producing medium circulation passes to refrigerating medium, and cold is discharged in the driving in air heat exchanger by refrigerating medium.This mode of operation because refrigerating medium thermal capacity is bigger, when continuing released cold quantity temperature fluctuation less, improved comfortableness, when avoiding the fixed displacement compressor operating, the shortcoming that the air outlet temperature fluctuation is bigger.
Fig. 2-b cold-storage mode of operation; The refrigerant circulation loop operate as normal; In the refrigerating medium closed circuit, through the refrigerating medium control device, refrigerating medium only passes through cold-accumulating box; The cold that evaporimeter discharged in the cold-producing medium circulation passes to refrigerating medium, and this cold-producing medium is stored in cold in the cold-accumulating box with certain low temperature.This pattern can be filled cold fast to cold-accumulating box, the cold of being stored can be at engine shutdown, or the cold-producing medium circulation is used to keep the refrigeration of driver's cabin when quitting work.
Fig. 2-c cold-storage discharges mode of operation; Refrigerant circulation loop quits work; In the refrigerating medium closed circuit, through the refrigerating medium control device, refrigerating medium is through cold-accumulating box and air heat exchanger; The cold that store in the cold-accumulating box this moment slowly is discharged in the driver's cabin in air heat exchanger through refrigerating medium.In the time of can satisfying engine cut-off, the refrigeration demand of driver's cabin also can reach energy-saving and cost-reducing purpose simultaneously.
Fig. 2-d cold-storage and refrigeration associated working pattern; The refrigerant circulation loop operate as normal is in the refrigerating medium closed circuit, through the refrigerating medium control device; Refrigerating medium passes through cold-accumulating box and air heat exchanger simultaneously; Can control the refrigerating medium flow of cold-storage side and refrigeration side according to air conditioner load automatically, the implementation part cold is used for cold-storage (refrigerating medium flows to 1-3-5-6-7-8-4-2), and the part cold is used for the operating mode of refrigeration (refrigerating medium flows to 1-3-7-8-9-10-4-2).When the vehicle motor high-speed cruising, under the demand that satisfies the normal refrigeration of driver's cabin, rich cold can be stored in the cold-accumulating box.
