WebCooling Capacity. Cooling capacity for a room is defined as the heat load in a room that have to be removed in order to achieve a certain room temperature and humidity. The typical design is set to 24°C temperature and 55% Relative Humidity. Study shows that this combination of temperature and RH is the most conducive for the human body. WebThe resulting uncertainty in the peak cooling load is mvent ventilation mass flow rate (kg/s) calculated in Section 6, and the main factors contributing to it are Qw exterior wall conductive heat flow (w/o windows) identified in Section 7 through a sensitivity analysis. A discussion (W) of the results is presented in Section 8.
