Thermoelectric cooling system

A thermoelectric subsystem for a thermoelectric cooling system, the thermoelectric subsystem comprising:

• a thermoelectric subsystem first heat exchanger having a thermoelectric subsystem first heat exchanger passage configured to receive a first refrigerant and to provide the first refrigerant;
• a first thermoelectric cell coupled to the thermoelectric subsystem first heat exchanger;
• a thermoelectric subsystem second heat exchanger coupled to the first thermoelectric cell opposite the thermoelectric subsystem first heat exchanger, the first thermoelectric cell fluidly separating the thermoelectric subsystem first heat exchanger from the thermoelectric subsystem second heat exchanger, the thermoelectric subsystem second heat exchanger positioned within a refrigerated enclosure;
• and
• a controller configured to perform operations comprising:
• controlling an operating parameter of the thermoelectric subsystem first heat exchanger;
• controlling an operating parameter of the first thermoelectric cell;
• and
• based on controlling the operating parameter of the thermoelectric subsystem first heat exchanger and controlling the operating parameter of the first thermoelectric cell, causing the first thermoelectric cell to provide a target rate of cooling to the refrigerated enclosure.
