<P>PROBLEM TO BE SOLVED: To provide an automatic dispenser including a separate cooling system and a cooling/heating system, in which functional units are disposed in a machine chamber so as to increase the chamber cooling efficiency of the cooling system and the chamber heating efficiency of the cooling/heating system. <P>SOLUTION: The automatic dispenser includes a flow channel switching valve 55 switching the flow channel of the refrigerant between a first compressor 53 connected to a cooling/heating cycle and a first heat exchanger 54, a second compressor 56 connected to a cooling cycle and a condenser 57 in a machine chamber 52. The first compressor 53, the second compressor 56 and an evaporation pan 60 are disposed horizontally in a rear area in the machine chamber 52. The first heat exchanger 54 and a plurality of condenser fans 61 behind the condenser 57 are separately operated respectively. With this, the heat radiation function from the first compressor 53 in the cooling/heating cycle is adjusted properly; i.e. cooling capacity is ensured during cooling and the heating capacity of the first compressor 53 is enhanced during heating operation, and thus, the power consumption is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
