On reliability measures assessment for the air conditioning system with rental equipment working in heavy weather conditions: Lz-transform approach

In this paper we present the model for estimation reliability measures of reserved of air-conditioning systems for hotels, apartments, offices or cooling rooms that have a specific regime of temperature/humidity conditions, which described as stochastic process. In this reservation mode the demand of the required temperature and humidity condition is provided by aging cooling generator (air-conditioner) with reserved generator orders from rented firm. The suggested approach is based on combined Lz-transform and stochastic processes method for computation of availability, performance and performance deficiency for multi-state system. The model takes into consideration the important factors such as cooling generator output, failure and repair rate, availability, time of supply of rented generator. Corresponding procedures are suggested. Numerical example is presented to illustrate the described approach.
