<P>PROBLEM TO BE SOLVED: To provide a natural circulation type (boiling circulation type) cooling system configured to prevent dew condensation of a heat exchange unit installed in a room. <P>SOLUTION: An outdoor unit 50 including an outdoor heat exchange unit 51 installed outdoors includes a refrigerant recovery unit 70 including at least one reservoir 71 connected in series or parallel to the outdoor heat exchange unit 51. The refrigerant recovery unit 70 has at least a capacity for recovering a refrigerant in a liquid state, the refrigerant circulating in a pipe system 60 during operation. As a result, a liquid refrigerant 65 to be supplied from the outdoor heat exchange unit 51 to an indoor heat exchange unit 41 is shut off by means of a valve group 80, the liquid refrigerant 65 circulating in a cooling system 30 can be entirely recovered to the outdoor unit 50, and the indoor heat exchange unit 41 can be dried out. <P>COPYRIGHT: (C)2013,JPO&INPIT |
