Abstract
Nowadays, solar-powered air conditioning has witnessed an increased progress because air conditioning system is almost a must in every building in Saudi Arabia where the outside temperature in summer is higher than 42°C. AlMadinah AlMunawwarah is one of the important holy places in the world, and therefore, this paper investigates the design and performance of solar-powered air conditioning system integrated with photovoltaic (PV) system which consists of PV panels, solar charger, inverter and batteries. This air conditioning system can be used in non-electrified areas near AlMadinah where the cost of electricity for this area is very high. The first step in this project is the cooling load calculations for the selected space that will be cooled and it was found about 1 ton refrigeration (3.52 kW). Based on this cooling load, the photovoltaic (PV) system has been estimated and built with the necessary connections. Data logging system has been used to measure the temperatures at the main components in the cycle like compressor inlet and outlet as well as evaporator and condenser. The input powers for the system as well as the coefficient of performance (COP) for the system under AlMadinah climatic conditions were measured along the day. The coefficient of performance varies from 2.16 to 4.22 for the system and these results compared with the conventional system performance with a good agreement.
Highlights
Ten years ago energy consumption for cooling has increased dramatically in Saudi Arabia
Design and Sizing of the Air Conditioning System Based on cooling load calculations, the air conditioning unit has been selected with the following specification: unit capacity 3.52 kW or 1 ton refrigeration (1 TR) split unit, 220 V, input power 1.250 - 1.374 kW to provide the suitable coefficient of performance (COP). 2.4
This work focuses on design, construction and testing the performance of solar-powered air conditioning system integrated with photovoltaic (PV) system and applying it under AlMadinah AlMunawwarah climatic conditions
Summary
Ten years ago energy consumption for cooling has increased dramatically in Saudi Arabia. (2015) Performance of Solar-Powered Air Conditioning System under AlMadinah AlMunawwarah Climatic Conditions. AlMadinah AlMunawwarah one of the most holy places has a very sunny climate, with high demand for air conditioning on hot summer’s days; the electricity grid increasingly faces the danger of overload due to air conditioner use, which would cause essential service disruption and severe economic impact. Solar air conditioning is one of the few solutions provided to overcome the summer high demand and addresses peak loading, and does so with reduced environmental impact at AlMadinah AlMunawwarah. In remote Saudi’s villages, far from the grids, electric energy is usually supplied by diesel generators. In most of these cases, the supply with diesel fuel becomes highly expensive.
