Combined drying and refrigerating storehouse

A combined drying and refrigerating storehouse, comprising:

• a housing having a heat pump unit chamber at its central portion and two combined drying and refrigerating chambers at its side portions, the heat pump unit chamber being divided from the combined drying and refrigerating chambers by two partition walls;
• two circulating chambers extended outwardly from the partition walls and extended vertically, said circulating chambers respectively communicating with upper and lower portions of the combined drying and refrigerating chambers and having blowers at their lower portions;
• a heat pump unit having a compressor, a four-way valve, first and second heat exchangers and a second condenser, the compressor, the four-way valve, the first heat exchanger, the second condenser, the second heat exchanger and the compressor being connected one after another by means of a first conduit, an outlet of said four-way valve being connected to an inlet of the compressor by means of a suction conduit, the compressor, the four-way valve and the second condenser being disposed in the heat pump unit chamber and the first and second heat exchangers being disposed in upper portions of the circulation chambers;
• a second evaporator disposed on a portion of a second conduit, said second conduit connecting the second condenser to a point on an output-side portion of the first conduit with regard to the second heat exchanger functioning as an evaporator;
• means for controlling a flow passage of coolant, said flow passage control means being disposed on the first and second conduits;
• and
• a control unit for controlling said four-way valve, said flow passage control means, etc.
