Development of Internet of Things (IoT) Technology and Its Applications on Room Cooling System

Abstract

This papers propose a physical model that includes the outdoor temperature to determine thermal characteristics of the room by using IoT technology. The physical model is used in the computation in the cloud. The thermal characteristics obtained is used to minimize the energy consumption in room cooling system. The temperature in the room can be also controlled by processing the thermal characteristics in real-time. This papers only show the compatibility of the model with the real experiments data. The physical model is obtained by using thermodynamics and transport phenomena concepts, which are heat capacity and thermal resistance. This model is tested by using 4 real room temperature data set and the thermal characteristics values obtained is analysed with plotting them to outdoor-indoor temperature difference. The physical model is compatible with the real temperature data. The thermal characteristics doesn’t vary much with the outdoor-indoor temperature difference. The thermal characteristics value when the compressor is on is higher.
