Again, the 1st commodity storage storehouse 30a is being used as heating, and with the 2nd and the 3rd commodity storage storehouse 30b, 30c as cooling with and operation time, control part 60, open the 3rd solenoid valve 51c, the 4th solenoid valve 51d, the 6th solenoid valve 51f, the 7th solenoid valve 51g and the 10th solenoid valve 51j, and close the 1st solenoid valve 51a, the 2nd solenoid valve 51b, the 5th solenoid valve 51e, the 8th solenoid valve 51h, the 9th solenoid valve 51i, and make compressor the 41, the 1st～the 3rd inside-of-refrigerator pressure fan 32a～32c operation.Like this, as shown in Figure 7, the cold-producing medium of compressor 41 ejections is flow through after the 1st inside-of-refrigerator heat exchanger 31a, flow through the 2nd and the 3rd inside-of-refrigerator heat exchanger 31b, 31c and suck compressor 41 through the 2nd and the 3rd expansion valve 52b, 52c respectively.At this, reach design temperature at for example storehouse temperature of the 2nd commodity storage storehouse 30b, and the storehouse temperature of the 1st and the 3rd commodity storage storehouse 30a, 30c is not when reaching design temperature, by closing the 3rd solenoid valve 51c and stopping the operation of the 1st inside-of-refrigerator pressure fan 32a, thereby cold-producing medium is flow through after the 1st inside-of-refrigerator heat exchanger 31a, flow through the 3rd inside-of-refrigerator heat exchanger 31c through the 3rd expansion valve 52c, suck compressor 41.Again, storehouse temperature at the 2nd and the 3rd commodity storage storehouse 30b, 30c reaches design temperature, and the storehouse temperature of the 1st commodity storage storehouse 30a is not when reaching design temperature, by closing the 3rd and the 4th solenoid valve 51c, 51d, and open the 9th and the 10th solenoid valve 51i, 51j, and stop the operation of the 2nd and the 3rd inside-of-refrigerator pressure fan 32b, 32c, thus cold-producing medium is flow through after the 1st inside-of-refrigerator heat exchanger 31a, flow through heat source side heat exchanger 42 through the 4th expansion valve 52d, suck compressor 41.
Again, the the 1st and the 2nd commodity storage storehouse 30a, 30b are being used as heating, when the 3rd commodity storage storehouse 30c is moved as cooling usefulness, control part 60, open the 4th solenoid valve 51d, the 7th～the 10th solenoid valve 51g～51j, and close the 1st～the 3rd solenoid valve 51a～51c, the 5th and the 6th solenoid valve 51e, 51f, and make compressor the 41, the 1st～the 3rd inside-of-refrigerator pressure fan 32a～32c and 43 operations of heat source side pressure fan.Like this, as shown in Figure 8, the cold-producing medium of compressor 41 ejection is flow through after the 1st and the 2nd inside-of-refrigerator heat exchanger 31a, the 31b, flow through the 3rd inside-of-refrigerator heat exchanger 31c and heat source side heat exchanger 42 and suck compressor 41 through the 3rd and the 4th expansion valve 52c, 52d respectively.At this, reach design temperature at for example storehouse temperature of the 1st commodity storage storehouse 30a, and the 2nd and the 3rd commodity storage storehouse 30a, when the storehouse temperature of 30c does not reach design temperature, by closing the 7th solenoid valve 51g, the 9th solenoid valve 51i, open the 5th solenoid valve 51e, and make the cold-producing medium in the 1st inside-of-refrigerator heat exchanger 31a return compressor 41, stop the operation of the 1st inside-of-refrigerator pressure fan 32a and heat source side pressure fan 43, thereby cold-producing medium is flow through after the 2nd inside-of-refrigerator heat exchanger 31b, flow through the 3rd inside-of-refrigerator heat exchanger 31c through the 3rd expansion valve 52c, and suck compressor 41.Again, storehouse temperature at the 1st and the 2nd commodity storage storehouse 30a, 30b reaches design temperature, and the storehouse temperature of the 3rd commodity storage storehouse 30c is not when reaching design temperature, by opening the 1st solenoid valve 51a, the 5th solenoid valve 51e and the 6th solenoid valve 51f, close the 7th～the 10th solenoid valve 51g～51j, and stop the operation of the 1st and the 2nd inside-of-refrigerator pressure fan 32a, 32b, thereby make cold-producing medium flow through heat source side heat exchanger 42, and flow through the 3rd inside-of-refrigerator heat exchanger 31c through the 3rd expansion valve 52c, and suck compressor 41.
Again, because when making the function of heat source side heat exchanger 42 performance evaporators, cold-producing medium is difficult to heat absorption when the extraneous air that carries out heat interchange is low temperature, so, by utilizing well heater 44 to come the cold-producing medium of heat hot source heat exchanger 42, thereby make the cold-producing medium heat absorption.
Like this, if adopt the automatic vending machine of this form of implementation, because flow through the inside-of-refrigerator heat exchanger of heated side and the commodity storage storehouse of heating heated side at the cold-producing medium that makes compressor 41 ejection, the cold-producing medium that the heated side heat exchanger is flowed out flows through the inside-of-refrigerator heat exchanger of cold side through expansion mechanism and cools off on the refrigerant loop 50 in commodity storage storehouse of cold side, switch the cold-producing medium that makes compressor 41 ejections flows through the inside-of-refrigerator heat exchanger of cold side through heat source side heat exchanger 42 and expansion mechanism stream, the cold-producing medium that flows out with the inside-of-refrigerator heat exchanger that makes heated side passes through the stream that heat source side heat exchanger 42 flows into compressors 41, so, the part of the cold-producing medium by making compressor 41 ejection flow through heat source side heat exchanger 42 and with heat source side heat exchanger 42 as condenser working, can utilize heat source side heat exchanger 42 to replenish the refrigerating capacity that needs in the commodity storage storehouse of cold side.Again, the part of the cold-producing medium that flows out by the inside-of-refrigerator heat exchanger that makes heated side flow into compressors 41 through expansion mechanism and heat source side heat exchanger 42 and with heat source side heat exchanger 42 as evaporator operation, can utilize heat source side heat exchanger 42 to come the heating efficiency that needs in the commodity storage storehouse of supplementary heating side.Like this, do not use under the situation of well heater 44, just can obtain sufficient heating efficiency, can significantly reduce power consumption in the commodity storage storehouse of heated side.
Again, because if close towards the stream of heated side inside-of-refrigerator heat exchanger, then make the cold-producing medium of compressor 41 ejections flow through heat source side heat exchanger 42, if and close towards the stream of cold side inside-of-refrigerator heat exchanger, then make the cold-producing medium that heated side flows out flow through heat source side heat exchanger 42, so, reach design temperature either party of the commodity storage storehouse of heated side or cold side, and when closing stream towards the inside-of-refrigerator heat exchanger, can utilize heat source side heat exchanger 42 obtain the opposing party the commodity storage storehouse heating or cool off needed heat, can often each commodity storage storehouse 30a～30c be remained on suitable temperature.
Again, because have the electric heater 44 of the cold-producing medium of heat hot source heat exchanger 42 sides, so, when heat source side heat exchanger 42 moves as evaporator and the extraneous air that carries out heat interchange is under the situation of low temperature, can utilize electric heater 44 heating to flow through the cold-producing medium of heat source side heat exchanger 42, but the supplementary heating ability.
In addition, in aforementioned form of implementation, though be depicted as the form of utilizing solenoid valve and non-return valve to carry out the switching of stream, solenoid valve also capable of being combined and carry out the switching of stream.
Again, in aforementioned form of implementation, use the form of expansion valve, also can use kapillary or expander as expansion mechanism though be depicted as.
