Title:
REFRIGERATING PLANT SYSTEM
Document Type and Number:
Japanese Patent JPS54136457
Kind Code:
A
Abstract:
A refrigeration system including multiple parallel compressors for maintaining evaporator suction pressures within preselected ranges, said compressors being sequentially and cyclically operative through control switch means responsive to preselected upper and lower refrigerant suction pressures, a fluidic time delay system for operating the pressure responsive switch means comprising restrictor means interposed between the common suction header for the compressors and the pressure responsive switch means therefor to restrict refrigerant fluid flow to the pressure switches upon increases in suction header pressure, and unidirectional flow means for providing unrestricted reduction of the pressure acting on the switch means upon relative decreases in suction header pressure.
