Abstract
This study describes to analyze the cooling load characteristics for a room air conditioner as a function of supply ventilation air when an air conditioner is running. An experimental apparatus consists of a test room, a room air conditioner, a humidifier, an electrical heater, a supply fan and a controller. The reaching time to the inside setting temperature of the room air conditioner with is evaluated theoretically and experimentally in a conditioned space cooling loads such as supply ventilation air, lighting, occupancy and infiltration. In the conditions of cooling loads for the supply ventilation air of 9.5 L/s(0.98 ACH), lights, one person, and infiltration, the reaching time to the inside setting temperature (27 ℃ dry-bulb) increases up to 35% more than for no supply ventilation air condition. Theoretical modelling of the reaching time shows good agreement with experimental results.
