PURPOSE:To restrict the condensation on a wall surface, limit an excessive increasing of temperature at a wet ball and shorten a transfer time for a stable air conditioning by a method wherein when condition of temperature and humidity is to be varied, control conditions for temperature and humidity are combined with a condition of wall temperature and a condition of dew point. CONSTITUTION:An outdoor room 3 is provided with an outdoor air conditioning device 6 and a temperature and humidity sensing device 8. Further, a sensor 13 for measuring a dew point at the outdoor side and a sensor 15 for measuring a wall surface temperature are arranged. The temperature and humidity are set such that a dry ball temperature signal and a wet ball temperature signal from the temperature and humidity sensor 8, a dew point signal from a dew point sensor 13 and a wall surface temperature signal from a wall surface temperature sensor 15 are inputted to a control circuit and then their conversion, comparison and calculation are performed. Further, they are combined with a timer signal from a delay timer part, outputted from the output part to a dry ball temperature adjusting meter and a wet ball temperature adjusting meter, passed through an electric power adjusting unit so as to control a heater and a humidifying heater. |
