The effect of the initial conditions on the functional indicators of microclimate maintenance systems

Lysyov V.I. , Parizhskaya Tatyana Andreevna

Outdoor climate parameters are always variable, both during the year and in long-term perspective, which leads to uncertain expenses on building microclimate maintenance systems. The great variety of facilities and their initial conditions predetermines a variety of possible technical solutions, and controversy of defining parameters with lack of recommendations on how to evaluate the influence of chosen design parameter on seasonal provision coefficient, and related to this circumstance calculated values of needed resources of heat and cold, makes it difficult to choose. The basis of choosing rational technical solution options is targeted consideration of the facility’s initial conditions with further analysis of alternative technical solution indicators. Due to the dependence of needed resource values both on the technical solution and on the operation mode, it is suggested to evaluate system’s functional indicators by the values of seasonal provision coefficient. The approach is explained on the example of specific facilities.
