Recently, confirmed patients of COVID-19 continue to occur in multi-use facilities, and cases of aerosol infection increase in non-ventilated spaces. As ventilation rate increases, the virus infection rate decreases exponentially, but forced ventilation for reducing the infection rate leads to energy loss. In this paper, a cafe was selected the same as the previous paper. TRNSYS18 was used to calculate the heating and cooling loads according to ventilation rates and methods. Based on this, the correlation with the infection rate was analyzed. During heating operation, the heating loads increased as ventilation rate increased, and the heating sensible loads were particularly affected. Ventilating with 3 ACH, the heating loads increased by 14 times for forced ventilation, compared to non-ventilated. Applying ERV, the heating loads increased by 3.5 and 3.3 times for the plate and rotary respectively. The cooling latent loads increased significantly as ventilation rate increased, compared to non-ventilated during cooling operation. Ventilating with 3 ACH, the cooling loads increased by 2 times for forced ventilation, 1.6 and 1.2 times for the plate and rotary respectively. When infected and non-infected people stay in the same space for 5 hours without wearing a mask, it is possible to keep the infection rate below 2% with 3 ACH. As a way to prevent the spread of COVID-19, ventilation is very effective, and considering energy savings, ERV introduction is essential.
