Abstract
A refrigerated transport system comprises: an engine. A vapor compression system comprises: a compressor for compressing a flow of a refrigerant; a first heat exchanger along a refrigerant flowpath of the refrigerant; and a second heat exchanger along the refrigerant flowpath of the refrigerant. A heat recovery system has: a first heat exchanger for transferring heat from the engine to a heat recovery fluid along a heat recovery flowpath; and a second heat exchanger along the heat recovery flowpath. The heat recovery system second heat exchanger and the vapor compression system first heat exchanger are respective portions of a shared tube/fin package.
Claims19
A refrigerated transport system comprising:
- a heat source;
- a vapor compression system comprising:
- a compressor for compressing a flow of a refrigerant;
- a first heat exchanger along a refrigerant flowpath of the refrigerant;
- and
- a second heat exchanger along the refrigerant flowpath of the refrigerant;
- a refrigerated compartment in thermal communication with the vapor compression system second heat exchanger;
- and
- a heat recovery system having:
- a first heat exchanger for transferring heat from the heat source to a heat recovery fluid along a heat recovery flowpath;
- and
- a second heat exchanger along the heat recovery flowpath,
- wherein:
- the heat recovery system second heat exchanger and the vapor compression system first heat exchanger are respective portions of a shared heat exchanger for rejecting heat to a heat transfer fluid;
- a separate subcooler has respective legs along the vapor compression flowpath and the heat recovery flowpath;
- and
- the heat recovery system first heat exchanger has respective legs along a coolant flowpath of the heat source and the heat recovery flowpath.
