Abstract
In hot climatic regions, some kind of cooling system is necessary to avoid warmth and humidity. Many of the available cooling systems are not economic and sustainable. In this study, sustainable and feasible space/room cooling systems have been experimentally analyzed. A solar operated cooling system with two options have been designed and their performances are compared. Phase Change Material (PCM) is proposed to store thermal energy instead of a costly battery. A 1200-watt compressor and fin-type condenser are used to construct the vapor compression system. When the incoming air is passed through the cooling coil, it gets cool. For this cooling coil, 50 feet copper tube is used. The front side copper tube diameter of the fan is 3/8 inch and the backside tube diameter is 1/2 inch. It took about 35 minutes and 5 minutes to minimize the room temperature at the desired level in the case of the stand fan and duct fan, respectively. Furthermore, the stand fan and duct fan systems reduced 3 ℃ and 6 ℃ of the outside temperature, respectively.
Highlights
A day, air cooling is obtained by using evaporative coolers, fans, dehumidifiers, and air conditioners (A/C)
There are some variables of weather conditions like cloud, temperature, dust, moisture, and humidity affect the performance of solar panel output
A sustainable room cooling system operated by solar power with a Phase Change Material (PCM) based storage is proposed with two output options
Summary
Air cooling is obtained by using evaporative coolers, fans, dehumidifiers, and air conditioners (A/C). Most of the above systems required huge capital and operating costs as well as electricity is required to operate these systems. Non-conventional energy sources or fossil fuels are used, which are responsible for environmental pollution and global warming. Many parts of the world have a scarcity of electricity. Some researchers have developed off-grid solar fan and A/C. Such systems require many PV panels to provide sufficient electricity, which is still expensive. Where the energy storage system (battery) is the most expensive part
