Abstract

Purpose: The research aims to design intelligent energy efficiency model for split type air conditioning (AC) to provide comfort to the occupant and energy saving.

Background: According to Malaysia Energy Information Hub, Energy information unit, Suruhanjaya Tenaga, total of electricity consumption for the residential and building sector has increased for about 53.7% and 14.6% of final energy demand in this country from 2000 to 2015, and projected two-fold raised in 2035. The highest distribution of energy use reported that 58% of the AC systems.

Design/Methodology/Approach: The control system of the AC consists of a temperature sensor inside building, an intelligent subroutine installed to the AC system. The sensor monitors the temperature of the inside building and emits electrical signals proportional to the state of the conditioned space. The output signal is supplied to the AC system, which sends out a control signal that is a function of the error between the value of the monitored temperature and the required set point temperature.

Results/Findings: A system with fuzzy logic controller can control the cooling capacity by changing the speed of the compressor in term of refrigerant flow for load matching and thermal comfort.

Conclusion and Implication: Using the proposed system, split-type AC gets significant improvements in energy efficiency and provides a better control than the on/off controller (thermostat).
