This paper conducts an experiment on the starting and stopping of an indoor air-conditioner in winter, and obtains a series of experimental data of the indoor environmental temperature. With these data, it makes a further calculation of the indoor PMV index during the start-up and shutdown of the air-conditioner. On condition that the human body's thermal comfort is basically guaranteed, an optimal combination mode of time is worked out to start and stop the air conditioner that operates intermittently in the experimental room. If the starting and stopping of the air-conditioner is managed in this way, the maximum energy-saving potentiality can be 41 % compared with the traditional continuous operation.
Keywords. air-conditioned room; intermittent operation; energy conservation potentiality; starting and stopping management of air-conditioner; thermal comfort
