Heat Recovery Methods

I often see people interested in heat recovery asking questions about desuperheating.  This mode of heat recovery is based on circulating a fluid such as water through a heat exchanger to aid in transferring heat from one location to another.  One of the major issues with utilizing the superheat of the discharge gas from a refrigeration systems is; there is not a lot of available heat!  The available superheat in the discharge gas from a compressor is only a small percentage of the the total available heat energy.
