CT: The development of renewable energy is on the rise worldwide because of the growing demand on energy, high oil prices, and concerns of environmental impacts. In recent years, progress on solar-powered air conditioning has increased as nowadays, air conditioning system is almost a must in every building if we want to have a good indoor comfort inside the building. Therefore, this paper focuses in the design and construction of a direct current (DC) air conditioning system integrated with photovoltaic (PV) system which consists of PV panels, solar charger, inverter and batteries. The air conditioning system can be operated on solar and can be used in non-electrified areas. As we all known, solar energy is cost effective, renewable and environmentally friendly.

N: 1. From air and present participle conditioning.
AC, abbreviation of air conditioning, by 1966.
A/C, A.C., abbreviations of air conditioning.
air conditioner (n): from air + agent noun from condition; along with air-conditioning, first attested 1909, originally an industrial process; main modern use in residences and office buildings is from 1930s.
2. The artificial control of humidity, temperature, purity and motion of the air within buildings and other enclosed spaces to secure human comfort or the best environment for a particular industrial operation.
3. The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking techniques of the time. Carrier treated the air inside the building by blowing it across chilled pipes. The air cooled as it passed across the cold pipes, and since cool air can’t carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature -and a new technology was born.
4. The first functional definition of air-conditioning was created in 1908 and is credited to G. B. Wilson. It is the definition that Willis Carrier, the “father of air conditioning” subscribed to:
- Maintain suitable humidity in all parts of a building.
- Free the air from excessive humidity during certain seasons.
- Supply a constant and adequate supply of ventilation.
- Efficiently remove from the air micro-organisms, dust, soot, and other foreign bodies.
- Efficiently cool room air during certain seasons.
- Heat or help heat the rooms in winter.
- An apparatus that is not cost-prohibitive in purchase or maintenance.
