Abstract

A cooling unit wherein devices are divided so as to be installed in each of an outdoor unit and indoor unit, for downsizing the indoor unit and reducing its pipe-line cost. The cooling unit disposes a compressor, a condenser and a liquid receiver R in the outdoor unit, and disposes an expansion means and an evaporator in the indoor unit. The outdoor unit comprises a first bypass pipe closed by a first bypass valve so as to open/close freely. The indoor unit comprises a second bypass pipe, which is closed by a second bypass valve so as to open/close freely. The units are connected by a liquid pipe used as a supply line for refrigerant or hot gas by selecting a refrigerant supply line among the bypass valves and the open/close valves, and by a gas pipe communicating the evaporator to the compressor.
