Experimental study of the effect of solar radiation on air conditioner condenser

One of the most widely used electrical appliances is compression refrigeration systems or air conditioners, the split type of which is one of the most used air conditioners in hot areas. In such coolers, condenser plays a key role in its efficiency. The aim of this study was to investigate the effect of solar radiation and environmental factors such as temperature, humidity and wind speed on the amount of electrical energy consumption of split air conditioners. The study was conducted experimentally in spring and summer. In order to study the effect of solar radiation, three different angles have been considered for the location of the condenser, which include south latitude, 45 degrees to the left and right, as well as east in the morning and west in the afternoon. The results show that when the condenser is in the 90 degrees position (east-west) due to reduced radiation, the amount of energy consumption is reduced by up to 6% compared to the zero degrees angle and parallel to the south.
