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： It is possible to realize flow rate control regardless of the scale on a load side or a piping system and to achieve energy saving. In a host control device (20) of a heat source system, a bypass valve opening command value is determined by an opening command value determination unit (22) such that a header differential pressure matches a target differential pressure value, and a target opening value according to the header differential pressure or the behavior of the bypass valve opening is set by a target opening value setting unit (24). A heating medium flow rate set value is determined by a heating medium flow rate setting unit (23) using the target opening value set by the target opening value setting unit (24) and the opening command value determined by the opening command value determination unit (22).

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 maintain a water supply temperature close to a target water supply temperature at the time of a change in the number of heat source machines operating. A heat source system of the present invention anticipates a case where a prescribed minimum flow rate is set for heat source machines that are subject to addition or removal, and calculates, as compensation temperatures, hot and cold water outlet temperatures of the heat source machines so that the water supply temperature in such a case will match a target water supply temperature (SA2), and changes the hot and cold water outlet temperature settings of the operating heat source machines to the compensation temperatures (SA4). After that, the heat source machines that are subject to addition or removal are either started up or stopped (SA6), and the set flow rate for the heat source machines that are subject to addition or removal is set to the minimum flow rate (SA7).
