The effect of a controlled cooling system on the solar array of DC air conditioner

Abstract

The present research is devoted to solve the problem of high energy consumption by air conditioners in summer. In order to eliminate domestic electricity for cooling purposes and rely directly on solar energy isolated from the grid connection and increases the performance of the solar panel by using front water spray cooling system for the panel, and by using Adruino as controller to control the cooling system. The experimental system setup arranged in Iraq at Al-taje site during the summer season at a room. The proposed system consists of an array of photovoltaic, battery used to store power, PWM charge controller, and DC air cooler, Adruino. During the examination of the system, The enhancement of the solar panel has a positive effect on long-term batteries and improves the battery life by which the charge and discharge when combined with a direct photovoltaic air conditioning system without refrigeration. Excess power generated from the PV panels is storage in the batteries, which make the system is the most familiar with Iraq's summer conditions.

Enhancing the Efficiency and Reliability of a Standalone Solar Energy System for Homes in Iraq

“…Iraq's entire land area is 437,072 km2, and its latitude ranges from 29 to 37 ° N. It is the 58th largest nation on earth and is situated in the central region's northern region [12]. However, these places are affected by the sun's beams' angle of incidence on Earth.…”

“…Table 1. A comparison of the horizontal and vertical solar energy [12]. From June through August, the northern region of the planet receives sunlight that is nearly vertical or vertical to it.…”

“…By 2020, it is desired that 23% of the region's fuel blend will come from renewable sources. The 33rd ASEAN Electricity Ministries Meeting, which took place on October 7, 2015 [12], made the decision. For renewable energy in ASEAN, Energy Integration into the Market (EMI) is another promising choice.…”
