Hybrid vapor compression/thermoelectric heat transport system
A hybrid Vapor Compression (VC) and Thermoelectric (TE) heat transport system is provided that maintains a set point temperature range of a chamber and includes a VC system and a TE system. The VC system includes a compressor, a condenser-evaporator connected to the compressor, a first valve connecting the compressor to an evaporator-condenser, and a second valve connecting the evaporator-condenser to a thermal expansion valve. The TE system includes TE modules, a first heat exchanger thermally connected with a first side of the TE modules which connects the first valve and the second valve, and a second heat exchanger thermally connected with a second side of the TE modules which connects the first valve and the second valve. In this way, the VC system and the TE system can be operated individually, in series, or in parallel to increase the efficiency of the hybrid VC and TE heat transport system.

a compressor comprising a first port and a second port;
a first heat exchanger connected to the compressor at the first port;
a first valve connecting the second port to a second heat exchanger and a third heat exchanger;
a second valve connecting the second heat exchanger and third heat exchanger to a thermal expansion valve wherein the thermal expansion valve connects the second valve to the first heat exchanger;
one or more TE modules comprising a first side of the one or more TE modules and a second side of the one or more TE modules;
the second heat exchanger thermally connected with the first side of the one or more TE modules where the second heat exchanger connects the first valve and the second valve;
the third heat exchanger thermally connected with the second side of the one or more TE modules where the third heat exchanger connects the first valve and the second valve; and
