Multi-temperature cold plate refrigeration system

A multi-temperature refrigeration system comprising:

• a compressor;
• a first inlet valve;
• a second inlet valve, the first and second inlet valves coupled to the compressor;
• a first cold plate in thermal communication with the first load space and having a first temperature sensor;
• a first evaporator coupled to the first inlet valve, the first evaporator being adjacent to the first cold plate and operable to selectively cool the first cold plate when the first temperature sensor records a temperature above a first temperature range;
• a second cold plate in thermal communication with the second load space and having a second temperature sensor;
• a second evaporator coupled to the second inlet valve, the second evaporator adjacent to the second cold plate and operable to selectively cool the second cold plate when the second temperature sensor records a temperature above a second temperature range;
• and
• a microprocessor programmed to open one of the first inlet valve and the second inlet valve in response to a signal.

A multi-temperature refrigeration system comprising:

• a refrigeration unit having:
• a compressor, a low pressure switch, a condenser, and a reservoir;
• a plurality of evaporator units fluidly coupled to the compressor, each evaporator unit having an inlet valve, a cold plate housing a eutectic material having a preferred temperature range, a temperature switch, an expansion device and an evaporator adjacent to the cold plate and operable to selectively cool the cold plate;
• wherein,
• one of the plurality of temperature switches will energize the compressor, and will selectively open at least one inlet valve while maintaining the remainder of the inlet valves in the closed position when the temperature sensor records a temperature above the preferred temperature range, and the low pressure switch will de-energize the compressor.
