Abstract
This study investigates the performance of the thermoelectric air conditioning (TE-AC) system smartly controlled by the Internet of Things (IoT)-based configuration for real tropical climatic application. Air cooling management was done through thermoelectric coolers, and an Arduino microcontroller with various sensors such as a temperature sensor, simple RF modules, and actuators was used to control the indoor climatic conditions based on outdoor conditions. The result shows that when the input power supply to the IoT-based TE-AC system is increased, the cooling capacity of the framework is also enhanced. Significant power and carbon emission reduction was observed for the IoT-based TE-AC system as compared to the TE-AC system without IoT. The IoT-incorporated system also ensures better microclimatic temperature control. Additionally, the system cooling capacity improves by 14.0%, and the coefficient of performance is increased by 46.3%. Thus, this study provides a smart solution to the two major energy harvesting issues of traditional air conditioners—an increase in energy efficiency by employing a TE-AC system and a further improvement in efficiency by using an IoT-based thermal management system.
Highlights
In regions with hot and humid climatic conditions, air conditioning systems are used for space cooling, which results in a large amount of energy consumption [1]
This paper examined the improvement in the cooling performance of a thermoelectric air conditioning (TE-AC) system upon the integration of an Internet of Things (IoT)-based smart thermal management system into the TE-AC system
The following conclusions are drawn from the findings: The cooling power of the TE-AC system increases with an increase in input power from 600 W to 720 W
Summary
In regions with hot and humid climatic conditions, air conditioning systems are used for space cooling, which results in a large amount of energy consumption [1]. Studies show that the common cause of this energy waste is mainly due to the poor architecture, planning, design, and construction of buildings and their energy control processes [4,5]. This shows that space cooling is one of the leading sources of energy consumption, and it is predicted that its demand will reach 80% by the year 2030. There is a need to build intelligent systems to control energy consumption for improving energy efficiency. To overcome the wastage of electric energy due to the manual controlling method, numerous remotely controlled automated systems are built for smart houses to increase power utilization efficiency [12]. The internet is used to remotely communicate with the automated system to manage and optimize the electricity expenditure of cooling systems, which accounts for the largest expenditure of power among commonly used household devices [13]
