摘要： PROBLEM TO BE SOLVED: To improve the accuracy of load estimating calculation by estimating a necessary cooled/heated water flow rate based on the relationship between a combustion amount and a cooled/heated water temperature without installing a sensor for measuring the flow rate. SOLUTION: A number switching control device is composed of individual control devices 31, 32, 33 for controlling respective absorption chiller/heaters and a number control device 35 for outputting start/stop commands to the individual control devices. The number control device determines the number of operating absorption chiller/heaters suitable for a load condition based on cooled/heated water inlet/outlet temperatures and combustion ratios transmitted from the individual control devices, and transmits the start/stop commands to the individual control devices. The individual control devices determine fuel input amounts so that the cooled/heated water outlet temperatures of the absorption chiller/heaters become temperatures set beforehand, and carries out the inputting/blocking of fuel to the absorption chiller/heaters according to the start/stop commands from the number control device.

摘要： PROBLEM TO BE SOLVED: To prevent crystallization of an absorbing solution while using cooling water at low temperature and thus, appropriately obtain energy saving effects. SOLUTION: Set temperature of cooling water for cooling an absorber 16 and a condenser 13 is determined based on temperature allowance which is a difference between crystal temperature in absorber inlet absorbing solution concentration (temperature to achieve crystallization of the absorbing solution having the concentration) and actual absorber inlet absorbing solution temperature (at each time point during operation). The absorber inlet absorbing solution concentration may be calculated from refrigerant temperature in the evaporator 15, absorber outlet absorbing solution temperature, absorbing solution temperature in a low-temperature regenerator 11 and refrigerant condensation temperature in the condenser 13.
