Abstract

A refrigeration control system includes: a refrigerant including a blend of a first refrigerant and a second refrigerant; an accumulator; a compressor that receives the refrigerant from the accumulator and compresses the refrigerant; a first heat exchanger disposed downstream of the compressor; a receiver disposed downstream of the first heat exchanger; a first valve disposed between the liquid-to-suction heat exchanger and the receiver; a second valve disposed between the receiver and a second heat exchanger, the second heat exchanger, where the second heat exchanger receives the refrigerant from the second valve and at least partially vaporizes the refrigerant and outputs the at least partially vaporized refrigerant to the liquid-to-suction heat exchanger; and a control module configured to selectively adjust a speed of the compressor based on adjusting (a) a temperature of air output from the second heat exchanger and into a space toward (b) a setpoint temperature within the space.
