A rooftop unit provides heating, cooling, and ventilation to a single HVAC zone. The supply fan provides air circulation rate of 1200 L/s. OA->> EA- ІНН CC HC conditioned space Ts RTU heat gain Consider a period when the space temperature is 26°C, the net heat gain to the space is 13 kW, and the RTU operates to deliver average supply air temperature (Ts) to keep the room temperature steady. Based on a sensible fluid heating/cooling approximation (pcp = 1.23 J/L · °C ), the average supply air temperature delivered by the RTU will be closest to which of the following values?
08°C O 11°C O 14°C O 17°C 20°C 23°C
