PROBLEM TO BE SOLVED: To provide a refrigerating equipment that can be used for an air conditioner, economically and efficiently operated by selecting the optimal operation mode of a compression freezer. SOLUTION: This freezing equipment is constituted by combining an absorption freezer having an evaporator E and a compression freezer having two or more compressors M1, M2, a first condenser C1 cooling by outside air or cooling water, a second condenser C2 connected having heat exchange relation with the evaporator E of the absorption freezer, a use side evaporator Ec providing a cooling effect, and a pipe circulating and connecting them. The compressors M1, M2 are connected in parallel with each other. The compressor M1 is connected by a pipe with the first condenser C1 at the discharge side, and the outlet side of the first condenser C1 is connected by a pipe with an inlet of the second condenser C2. The compressor M2 is connected at the discharge side with a pipe between the first and second condensers and is provided with a by-pass pipe 6 by-passing the compressor M2 in parallel with the compressor M2. The control valve V1 is provided to the by-pass pipe 6. A pipe on the discharge side of the compressor M2 and that of the compressor M1 can be connected by a pipe having a selector valve equivalent with a three-way valve. COPYRIGHT: (C)2004,JPO
