Title: System and method for controlling a refrigeration plant
Inventor: KEVIN KITCHING
IPC: F25B49/02
Filed: 2017-02-28
Abstract: A control system for controlling compressor operating capacity in a refrigeration plant 20 which comprises a bank of compressors 22, 40, 46 which collectively provide refrigerant suction pressure to a plurality of evaporators 34, 36, 38 and which are activated/deactivated according to a variable cooling load. The control system comprises at least one mass flow sensor which senses mass flow of refrigerant downstream of the evaporators and at least one pressure or temperature sensor which senses pressure or temperature of refrigerant flowing between the evaporators and the compressor bank. One or more processing units (52a-c, fig. 4) receive outputs of the sensors, determine a cooling load using the sensed mass flow and the sensed refrigerant pressure or temperature to establish a feedforward demand, and compare the sensed refrigerant pressure or temperature with a target value to establish a feedback demand. The processing unit(s) combine the feedforward and feedback demands to establish an output demand and output a compressor operating capacity control signal according to the output demand. The processing unit(s) may control compressor capacity by activating/deactivating individual compressors in accordance with variations in cooling load, the compressors being activated to meet an increasing cooling load in a predetermined queue sequence.
