Abstract

In Malaysia, the hot and wet climate is the reason of high demand of the usage of air conditioner. However, the electrical power consumption by air conditioners are high. Therefore, there is an alternative technology that uses renewable energy like solar to reduce electrical bill. Solar photovoltaic commonly acts as the power source that generates direct current to electrical system. The electrical power that is generated from the photovoltaic panel could be used to power up the air conditioner. The solar power air conditioners usually required battery as their backup system. The battery bank discharges the electrical power whenever the photovoltaic modules do not generates electric due to cloudy days of or during nights. This project therefore focuses on the backup system for solar-powered air conditioner by using readily condensed refrigerant and evaporated refrigerant. The condensed refrigerant from condenser will be stored in a receiver in high temperature and high pressure. While the accumulator will store the evaporated refrigerant from the evaporator at low temperature and low pressure. This backup system will run whenever the solar photovoltaic modules cannot provide electricity to compressor. The prototype is designed by using SolidWord software. The COP of the backup system prototype is 3.57. An experiment has been done to determine the total mass of the refrigerant required to backup the system for one hour operation and the total mass for refrigerant is 18.9 kg which is equal to five receiver tanks. As the conclusion, the receiver tanks can be used as the backup system for solar-powered air conditioner.
