ABSTRACT:
An accessory device for conventional refrigeration systems that include an auxiliary compressor of lower capacity piped in parallel with the compressor of the conventional system. The auxiliary compressor cuts in after a certain temperature is reached and automatically the speed of the fan is decreased to compensate for the lower capacity of the system. Time delays are incorporated to each of the compressors to allow the high and low pressure ports to equalize.
