Compressor discharge converter

In a process fluid chilling system of the kind comprising a compressor, a discharge service valve mounted on the discharge port of the compressor, a condenser and a refrigerant-to-process fluid heat exchanger connected together in the stated sequence by refrigerant conduits, the improvement comprising a compressor discharge converter for connecting a second condenser into the system in series, comprising:

• a housing mountable on the compressor interposed between the compressor outlet and the discharge service valve, the housing comprising first and second separate transfer chambers, each chamber having a central port at the center of the converter and an external port at the periphery of the converter, the central port of the first transfer chamber connecting directly to the compressor discharge port and the central port of the second transfer chamber connecting directly to the discharge service valve,
• the central port of each transfer chamber being connected to the external port of that chamber by a plurality of small tunnel passages thereby affording a thin, flat configuration for the converter;
• and conduit means connecting the external ports of the converter to a second condenser so that the second condenser is connected in the system in series with the first condenser.
