AIR CONDITIONING SYSTEM, AND AIR CONDITIONING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress that the total sum of high-temperature cold water and low-temperature cold water becomes an excessive flow rate (flow rate excess).SOLUTION: A current treatment heat quantity with respect to a rated cooling capacity of an air conditioner is calculated as the current processing capacity ratio of an air conditioner, an upper limit value &thetas;1 max of an opening &thetas;1 of a high-temperature cold water valve is obtained from an opening &thetas;2 of a low-temperature cold water valve which is acquired by a feed air temperature control part 16A in summer and the current processing capacity ratio of the air conditioner, and a high-temperature cold water excess flow rate suppression control part 16D which uses the obtained upper limit value &thetas;1 max of the opening &thetas;1 of the high-temperature cold water valve as the opening &thetas;1 of the high-temperature cold water valve of high-temperature cold water excess flow rate suppression control is arranged at an air conditioner controller 16.
