Description
Summary:Calculating air exchange according to existing methods, dilutions of all heat surpluses and other hazards are taken into account. This leads to a significant overestimation of the amount of supply air and saving unreasonable costs. To solve the problem of cost optimization, the authors propose a displacement ventilation and air conditioning system. In this case, the supply air is supplied to the lower zone, where the congregation is located. In this case, it is proposed to calculate the air exchange for the assimilation of only part of the heat surplus and other harmful substances entering only the lower zone, up to 2,5 meters high from the floor level. The rest of the hazards are displaced by convective flow and supply air to the upper zone and removed to the outside. The proposed solution to the problem allows you to optimize the cost of ventilation and air conditioning in the halls of worship of Orthodox churches.
