Abstract:
A chiller apparatus comprising:a primary circuit including a chiller and a pump for circulating a refrigerant through said primary circuit;a secondary circuit including a pump for circulating, through said secondary circuit, a refrigerant heat-exchanged with the refrigerant of said primary circuit;a buffer tank arranged at said secondary circuit;at least one load circuit including a pump for circulating a refrigerant thorough said load circuit to chill a load;communication flow passages for connecting said secondary circuit and said load circuit to each other therethrough;one of said communication flow passages being provided with a valve for controlling a refrigerant flowing through the communication flow passage;said load being provided with a first temperature detection mechanism for generating a load temperature signal;at least one temperature control mechanism for receiving said load temperature signal and controlling a degree of opening of said valve based on said load temperature signal to thereby control a temperature of said load.
