Abstract
Stopping air conditioning system in a few minutes, passive indoor temperature change will be caused. The Passive Rhythming Air Conditioning System is a new proposal for air conditioning method using this temperature change. This method repeats passive temperature change once or twice an hour. To stop air conditioning system is one of the most effective energy conservation method. But, the influence of temperature change on thermal comfort should be examined. This paper describes the results of subjective experiments on the effects of passive temperature change on thermal comfort conducted in summer season. The main results are as follows; 1) There are no difference on thermal comfort between the Passive Rhythming Air Conditioning System and ordinary (constant temperature control) system in case of 26℃ of base temperature. 2) In case of 5 and 10 minutes of stopping period in the Passive Rhythming Air Conditioning System, subject's vote on comfort are rather better than ordinary systems. 3) It is suggested that the Passive Rhythming Air Conditioning System is the favorable air conditioning system especially for females.
