Abstract:
1. A plant, comprising: a compressor for compressing a compressible media; a heat recovery heat exchanger; the heat recovery heat exchanger configured in a heat recovery branch to recover at least a portion of an excess heat in the compressible media as a recovered heat; a heat-driven coolant chiller; the heat recovery heat exchanger configured to thermally connect with the heat-driven coolant chiller wherein at least a portion of the recovered heat is used to drive the heat-driven coolant chiller; a heat sink; the compressor further includes a compressor heat exchanger configured to recover a remaining portion of the excess heat in the compressible media as waste heat, the compressor heat exchanger being configured to connect with the heat sink to reject the waste heat; the compressor includes a compressible media outlet, wherein a plurality of the heat recovery heat exchangers, including the heat recovery heat exchanger, are arranged in-line between the compressible media outlet and the compressor heat exchanger; the plurality of heat recovery heat exchangers includes: a first heat recovery heat exchanger configured to recover a high-temperature portion of the excess heat for driving a first heat-driven load; and a second heat recovery heat exchanger configure to recover a mid-temperature portion of the excess heat for driving a second heat-driven load; wherein one of the first heat-driven load and the second heat-driven load include the heat-driven coolant chiller.
