PURPOSE:To improve efficiency of transportation and installation and to avoid extra generation of refrigerant by constituting a casing of a part to support a heat pump device and other parts so that these parts can be separated from and combined with each other. CONSTITUTION:A casing 4 is designed to be divided, as indicated by X-X and Y-Y lines, in an upper part excluding a base frame 1 into a central part 4A as a casing part to support mainly a heat pump device, a lefthand part 4B as another casing part to support an indoor air circulating fan 14, and a righthand part 4C as a further casing part to support an outdoor air introducing fan 15. Thus the casing 4 is constituted to be divided into the respective parts 4A, 4B and 4C and these parts are, in turn, to be combined into the casing 4. By this, efficiency of transportation and installation can be improved, and further extra generation of refrigerant can be avoided. |
