Keller, G W; Yaeger, R J

A waste heat recovery system for use with refrigeration means and a hot water reservoir is disclosed. The system is intended for use with refrigeration means of the type including a compressor and a condenser through which a compressible refrigerant is circulated. The system includes a heat exchanger having a refrigerant passage and a water passage mutually coupled in heat exchange relation. A heat exchange circulation conduit connects the water passage of the heat exchanger in fluid communication with the hot water reservoir to permit water to be circulated from the reservoir to the heat exchanger and return. A precharged refrigerant conduit connects the outlet port of the compressor in fluid communication with the condenser and includes a pair of bypass conduit sections terminated by quick connect/disconnect coupling members for connection to the refrigerant passage of the heat exchanger. A shut-off valve is connected in series fluid circuit relation in the refrigerant conduit intermediate the upstream and downstream bypass sections. The refrigerant passage of the heat exchanger is also precharged and includes inlet and outlet conduit sections having complementary quick connect/disconnect coupling members for engagement with the corresponding quick connect coupling members of the bypass conduit sections.
