The share of energy consumption for air conditioning and ventilation in the energy balance of industrial and public buildings can reach depending on the destination and time of year is very significant values of 25 to 50% [1]. For abandoned underground and covered car parks, this figure may be even higher and reach values of 60%. This is explained by significant volumes of fresh air required for the assimilation of the exhaust gases. Depending on the purpose and technical parameters of the car park specific air flow needed for the assimilation of the exhaust gas can be from 6 to 16 m3 / m2h. One of the reserves to improve energy efficiency of HVAC systems is to use the recovery and recycling of air flow [1]. However, now the recovery in ventilation systems, parking gated almost never used. Emissions is an obstacle to the use of recirculation air heating systems. As part of this article explains how to choose the scheme of ventilation without heat recovery and recycling in terms of the energy efficiency of air distribution scheme indoor car park.
