Abstract
Clean rooms, including operating rooms, are energy-intensive. During their operation, the concentration of particles in the air, air temperature and humidity are strictly monitored. HVAC systems in the operating room are subject to high demands on maintaining a stable heat and humidity microclimate, as well as particle concentrations within the permitted range. To cover heat losses and heat loads of the building, it is necessary to dimension ventilation equipment with high outputs and high energy consumption. By suitable optimization of the dispositional location of the operating tract in the building and the use of suitable thicknesses of insulating material, it is possible to reduce the performance requirements for the HVAC system, which significantly reduces energy consumption. Heat loss and heat load of the operating tract were evaluated using TechCon software. The performance values of the heaters and coolers for the HVAC units were calculated in the VentiCad design software. The optimization indicates a significant reduction in heat loss and heat load, as well as a reduction in the required temperature of the air supplied to the room by more than 10°C.
