PROBLEM TO BE SOLVED: To miniaturize an indoor unit and to reduce piping cost, in a cooling apparatus wherein configuration equipment is divided into an outdoor unit and the indoor unit and is installed. SOLUTION: In this cooling apparatus 40, a compressor CM, a condenser CD and a liquid receiver R are disposed in the outdoor unit 12, and an expansion means EV and an evaporator EP are disposed in the indoor unit 14. The outdoor unit 12 has a first bypass pipe 46, and the first bypass pipe 46 is openably and closably closed by a first bypass valve 48. The indoor unit 14 has a second bypass pipe 52, and the second bypass pipe 52 is openably and closably closed by a second bypass valve 54. Both the units 12, 14 are connected by a liquid pipe 22a used as a supply passage for both a refrigerant and a hot gas by refrigerant supply passage selection of both opening/closing valves 50, 56 and both the bypass valves 48, 54, and a gas pipe 22b performing communication from the evaporator EP to the compressor CM.
