摘要： A flow rate of a heat transfer medium is computed without a flow meter. In a control apparatus (30), a storing portion (36) stores an aerodynamic characteristic map indicating a line causing a rotating stall and lines showing a sonic velocity in a refrigerant sucked in by a compressor (12) on a map displaying a variable ¸ reflecting a suction volume of the compressor (12) and a variable Q reflecting a head of the compressor (12); a estimation portion of chilled water flow rate (30b) computes the variable Q, derives the variable ¸ according to the variable Q from the map, computes a heat amount exchanged between the refrigerant and the chilled water in an evaporator (24) based on the suction volume of the compressor (12) according to the computed variable ¸, and computes the flow rate of the chilled water based on the heat amount.

摘要： A turbo chiller that can run continuously even with a low load, for example, less than 10% load, is provided. In a turbo chiller having a low-load mode for repeatedly controlling stopping and starting of the turbo chiller when a coolant inlet temperature measured by a coolant inlet temperature sensor is equal to or lower than a first temperature forming a temperature difference with respect to the coolant outlet temperature, a stop limit mode for stopping the turbo chiller when the coolant inlet temperature or the coolant outlet temperature is equal to or lower than a second temperature below the first temperature is provided.

摘要： The purpose of the present invention is to provide refrigerant circulation devices and a refrigerant circulation method which are capable of inhibiting a refrigerant comprising a hydrofluoroolefin (HFO) or hydrochlorofluoroolefin (HCFO) from decomposing and thereby generating an acid. One of the refrigerant circulation devices is a refrigerant circulation device (1) which includes a compressor (3), a condenser (5), expansion valves (9, 19), and an evaporator (11) that have been connected to each other by main piping (17a to 17e) to configure a refrigerant circulation circuit for circulating a refrigerant therethrough, and into which a refrigerant comprising an HFO or HCFO each having a carbon-carbon double bond in the molecular structure has been packed. The refrigerant circulation device (1) is equipped with a drive (15) for driving the compressor (3) via a speed increaser (13) and with a drive-cooling part (25) for cooling the drive (15) with the refrigerant condensed in the condenser (5), a desiccant which can trap water having been disposed in the evaporator (11) or the drive-cooling part (25).
