Claim Text:
1. An air conditioning method of regulating temperature and humidity of process air to deliver it as supply air, the air conditioning method comprising: in an air conditioning system including: measuring equipment that measures flow rates, pressures, temperatures, relative humidities of the process air and the supply air, a flow rate and a temperature of humidifier water, and an atmospheric pressure; and an arithmetic unit that receives first measured values from the measuring equipment and calculates an absolute humidity x the arithmetic unit previously storing relationship among the relative humidity of the process air, a ratio of a limit amount of cooled-dehumidified air that indicates the amount of air to be cooled and dehumidified at a minimum flow rate to the amount of the process air, and a dehumidification temperature, and calculating the required amount of cooled-dehumidified air based on the previously stored relationship and the first measured values from the measuring equipment, when the absolute humidity x causing the required amount of cooled-dehumidified air calculated by the arithmetic unit out of the amount of the process air to flow downstream as a main stream in a main-stream duct in which a cooling dehumidifying unit, a heater and a humidifier are mounted; and causing the remainder of the amount of the process air, wherein the remainder of the amount of the process air is the amount of process air minus the required amount of cooled-dehumidified air, to flow downstream as a side stream in a side-stream duct in which a regulator is provided for regulating a flow rate of the process air in the side-stream duct, and when the absolute humidity x causing the required amount of cooled air out of the amount of the process air to flow downstream as a main stream in the main-stream duct in which a cooling unit, the heater and the humidifier are mounted; and causing the remainder of the amount of the process air, wherein the remainder of the amount of the process air is the amount of process air minus the required amount of cooled air, to flow downstream as a side stream in the side-stream duct in which a flow-rate regulator is provided for regulating a flow rate of the process air in the side-stream duct.
