Description
Summary:Appropriate spatial temperature sensing is recognized as one of the main challenges for thermostats used in air conditioners. In this study, a motivation is emerged to change this return-air-sensing by integrating the concept of distributed environment sensing toward the air-conditioning system (DES-A/C). An improved A/C system was established incorporating distributed environmental sensing by wireless sensor networks. Experimental research with two different treatments, single-point and multi-point user-neighborhood sensing, has been conducted to demonstrate the feasibility of this concept. It has been revealed that DES-A/C could save 43% energy compared to conventional A/C. In addition, DES-A/C could maintain the predicted mean vote (PMV) index in satisfaction range (−1
