Room temperature in a high heat-generating machine room increases with time after a shutdown in air-conditioning units according to the heat capacity of devices installed in the same room and along the outside of the building. This paper reports on the following studies that examined simple and convenient methods for evaluating and improving the reliability of air-conditioning system. 1) A method is presented for determining the probability that room temperature will exceed allowed temperature after a shutdown in air-conditioning units. Using this method, a simple method is proposed for calculating the reliability of air-conditioning system. 2) Using this simple calculation method, simulations are performed to investigate a method for improving the reliability of air-conditioning facilities in a high heat-generating machine room. 3) Taking into account the fact that the cooling performance of air-conditioning equipment changes according to temperature conditions, it is shown that the number of necessary air-conditioning units can be reduced while maintaining the same level of reliability.
