REFRIGERANT CIRCUIT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To obtain refrigerant circuit equipment capable of precisely obstructing the mix of refrigerant into an oil tank storing the oil separated by an oil separator. SOLUTION: Refrigerant circuit equipment is provided with oil separators 2a and 2b for separating the oil from the discharged refrigerant of a plurality of compressors 1a to 1d that are connected in parallel, and an oil tank 9 storing the oil separated by the oil separators 2a and 2b and having oil feeders 10a to 10d controlling the feed of oil to the compressors 1a to 1d from the oil tank 9 according to the height of the oil level of the compressors 1a to 1d. There are provided oil-circuit electromagnetic valves 20a and 20b opening and closing the circuits between the oil separators 2a, 2b and the oil tank 9 according to the operation/stop of the compressors 1a to 1d.
