ABSTRACT:
Known systems for recovering heat from refrigeration plant make no distinction between the different kinds of heat being recovered and use both low and high grade heat together to raise the temperature of say a water tank. The present invention provides a system in which low grade heat i.e. recovered latent heat is recoverable for low temperature heating loads, separately from superheat energy for high temperature loads. The system includes a countercurrent heat exchanger located between the condenser and compressor of a refrigeration plant, heat engine or like device recovered superheat from the exchanger being conducted to high temperature load and recovered latent heat from the exchanger being led to a low temperature load by heat transfer medium circulated through the heat exchanger and loads by a pump.
