Air conditioning system control method

Abstract

To provide a control method of an air-conditioning system capable of suppressing risk of delay of operation start of a coating step.SOLUTION: A control method of an air-conditioning system 10 adjusts air of a first coating booth B1 and a second coating booth B2. The air-conditioning system 10 includes a first air-conditioner 1, and a second air-conditioner 2. The first air-conditioner 1 is supplied with at least air discharged from the first coating booth B1, heats or cools the supplied air, and delivers the heated or cooled air to the first coating booth B1. The second air conditioner 2 is supplied with outside air or the air discharged from the second coating booth B2, heats or adjusts the temperature / humidity of the supplied outside air or air discharged from the second coating booth B2, and delivers the air to the second coating booth B2. The control method includes a step of determining whether at least one of a temperature T1 of a skeleton of the first coating booth B1 and a temperature T2 of a skeleton of the second coating booth B2 is lower than a predetermined value.SELECTED DRAWING: Figure 2
