Optimum Energy Management for Air Conditioners in IoT-Enabled Smart Home

Abstract

This paper addresses the optimal pre-cooling problem for air conditioners (AC) used in Internet of Things (IoT)-enabled smart homes while ensuring that user-defined thermal comfort can be achieved. The proposed strategy utilises renewable energy generation periods and moves some of the air conditioning loads to these periods to reduce the electricity demand. In particular, we propose a multi-stage approach which maximises the utilisation of renewable energy at the first stage to satisfy air conditioning loads, and then schedules residual energy consumption of these loads to low price periods at the second stage. The proposed approach is investigated for the temperature and renewable generation data of NSW, Australia, over the period 2012−2013. It is shown that the approach developed can significantly reduce the energy consumption and cost associated with AC operation for nearly all days in summer when cooling is required. Specifically, the proposed approach was found to achieve a 24% cost saving in comparison to the no pre-cooling case for the highest average temperature day in January, 2013. The analysis also demonstrated that the proposed scheme performed better when the thermal insulation levels in the smart home are higher. However, the optimal pre-cooling scheme can still achieve reduced energy costs under lower thermal insulation conditions compared to the no pre-cooling case.

A Sustainable Pattern of Waste Management and Energy Efficiency in Smart Homes Using the Internet of Things (IoT)

“…The study of Philip, Islam [29] addresses the issue of user-defined indoor thermal while investigating the optimal pre-cooling problem for air conditioners (AC) utilized in IoT (IoT)-enabled smart homes. The suggested approach makes use of the times when renewable energy was generated and shifts some of the air conditioning loads to these times in order to lower the demand for electricity.…”

The Green Cooling Factor: Eco-Innovative Heating, Ventilation, and Air Conditioning Solutions in Building Design

“…Facility managers or homeowners can remotely inspect and modify system settings using a smartphone application or web interface. According to Philip et al [63], this feature facilitates proactive system maintenance and increases usability. These systems are also capable of self-diagnosing issues and sending maintenance reminders.…”

Development of Design Optimization for Smart Grid (DOfSG) Framework for Residential Energy Efficiency via Fuzzy Delphi Method (FDM) Approach

“…Another critical design factor is the design, sizing and location of glazing which in this research shall concern the daylighting and artificial lighting use in homes. Integrated HEMS and IoT (internet of things) allow autonomous control of lighting and solar gain entering the building that affects indoor thermal comfort (Philip et al, 2022).…”
