ABSTRACT
One of the principal goals of an air conditioning system is to remove heat and moisture from the interior of a space to improve the comfort of occupants in residential and office buildings. As opposed to air conditioning systems in residential and office buildings, air conditioning systems of chemical laboratories, and especially ventilation and air movement equipment, need to have high reliability levels to provide the personal and environment safety. Increased reliability levels of such systems are achieved by redundancy of the systems' elements: exhaust systems and air handling units with several reserved blowers, working in different reservation modes. A special technique known as Lz-transform has been proposed and investigated for discrete-state continuous-time Markov processes. The Lz-transform approach simplifies the solution, in comparison with the straightforward Markov method, which would have required the construction and solution of a model with 2048 states for the air conditioning system for a chemical laboratory.
