    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 θ reflecting a suction volume of the compressor (12) and a variable Ω reflecting a head of the compressor (12); a estimation portion of chilled water flow rate (30b) computes the variable Ω, derives the variable θ according to the variable Ω 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 θ, and computes the flow rate of the chilled water based on the heat amount.

    摘要: A heat-source system includes centrifugal-chillers, cooling-water pumps, cooling towers, cooling-tower fans, chilled-water pumps, and a control unit for controlling them. A plurality of the cooling towers are provided so as to have a cooling-tower capacity corresponding to the total capacity of the rated capacities of the respective centrifugal-chillers, the cooling towers being commonly connected to the plurality of centrifugal-chillers. The control unit preliminarily prepares an optimum cooling-tower capacity relationship representing the cooling-tower capacity with which the heat-source system efficiency, taking into consideration the centrifugal-chillers, the cooling-water pump, the cooling towers, the cooling-tower fan, and the chilled-water pump, is higher, in relation to the outside-air wet-bulb temperature and the centrifugal-chiller partial load factor. The control unit determines the number of cooling towers to be operated by referring to the optimum cooling-tower capacity relationship, on the basis of the outside-air wet-bulb temperature and the partial load factor of the centrifugal-chillers during operation.

    摘要: A required-circulated-refrigerant flow-rate calculating portion provided in a chilled-water flow-rate estimation calculation portion calculates an evaporator exchanged heat quantity exchanged between a refrigerant and chilled water at an evaporator based on a planned chilled-water-flow-rate value and a measured value of the temperature of the chilled water flowing in the evaporator, and calculates an evaporator-refrigerant flow rate based on that evaporator exchanged heat quantity. Then, a circulated-chilled-water flow-rate back-calculating portion back-calculates an evaporator-refrigerant flow rate based on the calculated evaporator-refrigerant flow rate and a ratio between a set value of differential pressure between a condenser and the evaporator and a measured value of that differential pressure, back-calculates an evaporator exchanged heat quantity exchanged between the refrigerant and the chilled water at the evaporator from the back-calculated evaporator-refrigerant flow rate, and back-calculates the flow rate of the chilled water.
