On Availability Comparison of Reservation Modes for Multi-state Air Conditioning Systems Using Markov Approach

In this paper we compare different reservation modes of Air conditioning systems for apartments, offices or cooling rooms that have a specific regime of temperature/humidity conditions. In the first reservation mode the required temperature and humidity conditions are provided by two cooling chillers (conditioners) with reserved chiller staying in cold reserve. In the second mode the reserved chiller orders from rented firm. Markov Models are built for comparison analysis of possible operation modes. The model takes into consideration the important factors such as cooling generators output, failure and repair rate, availability, time of supply of rented chiller. A numerical example is presented to illustrate the described approach.
