摘要

PROBLEM TO BE SOLVED: To provide an air conditioner system capable of cooling to a temperature lower than a set minimum temperature set by a normal operation. An air conditioner system including an air conditioner 18, a system temperature detecting means 38, and a system controller 36 for operating and controlling the air conditioner 18. The air conditioner 18 includes an air conditioner main body 30, an air conditioner temperature detecting means 34, and an air conditioner controller 32, and the air conditioner controller 32 controls the air conditioner main body 30 based on a signal from the air conditioner temperature detecting means 34. When the air conditioner 30 is used to maintain the second low temperature temperature lower than the first low temperature temperature (18 ° C.), the air conditioner controller 36 operates and controls the air conditioner body 30 based on the signal from the air conditioner temperature detecting means 34 to control the temperature adjustment space. When the space temperature of the air is lowered to the second low temperature, the operation of the air conditioner 18 is stopped based on the detection signal of the system temperature detecting means 38.
