Ensuring optimal parameters of microclimate in the premises of buildings

Purpose. Health, wellbeing and productivity of a person largely depends on the factors of the internal environment of the premises, in particular on the parameters of the microclimate. The greatest impact of parameters such as temperature, the mobility and the relative humidity of the indoor air. The basis for the normalization of parameters of microclimate in the premises and workplaces are ДСН 3.3.6.042-99 ?Санітарні норми мікроклімату виробничих приміщень?, ГОСТ 12.1.005-88 ?Общие санитарно-гигиенические требования к воздуху рабочей зоны? and other normative documents and recommendations. Norms aimed at ensuring the optimal and permissible ranges, the maintenance of which can lead to the uncomfortable state of a man. Therefore, it is necessary to maintain the parameters of indoor environment of buildings in the required ranges, possibly due to the operation of the life support systems. Findings. Having considered each of the life support system of the building separately, namely system heating/cooling, ventilation and air conditioning, it was found that the optimal parameters of microclimate in the premises of the buildings is not possible without the complex operation of these systems. Heating system capable of maintaining at a predetermined level the indoor temperature suitable to the conditions of thermal comfort and the process requirements. The ventilation system is able to ensure the maintenance of the required level of a wide set of parameters of the air temperature (not in all cases), mobility (speed), relative humidity (not in all cases), the dust, the concentration of harmful substances. The air conditioning system, unlike ventilation, provides not only the necessary change of air, but also automatically maintains the specified conditions it is not dependent on external climatic factors and the internal operation mode in the room. Practical value. Integrated job support systems of the buildings will improve the microclimate in the premises, and to increase the productivity of human labor.
