<P>PROBLEM TO BE SOLVED: To secure a predetermined temperature difference even at a low load of a load side air conditioner and return a cold/heat medium to a heat source side, to not only reduce transfer power but also improve a system COP of a heat supply facility. <P>SOLUTION: In the air conditioning system, a heat source part 2 including a cold/heat source machine 1 and a load part 4 formed by connecting a plurality of air conditioning systems in parallel are interconnected via a heat exchanger 5. The cold/heat medium is supplied from the heat source part 2 to each air conditioning system of the load part 4 via the heat exchanger 5, and is returned from an air conditioner in each air conditioning system to the heat source part 2 side via the heat exchanger 5 again. A plurality of return pipes 11, 12 divided according to outlet temperature characteristics of the cold/heat medium of an air conditioner coil of each air conditioning system are provided. The respective pipes 11, 12 are arranged in descending order of a return temperature difference on the load side, and heat exchangers 5a, 5b provided in the return pipes 11, 12, respectively are interconnected in series. <P>COPYRIGHT: (C)2012,JPO&INPIT |
