NATURE AND IMPORTANCE OF THE STUDY

Introduction

Technology brings comfort and convenience to the lives of people. It is a fact that

technology could do wonders in the field of industry, medicine, agriculture and

communication. However, it cannot be denied that it is also one of the culprits to

what is happening to our environment such as the occurrence of climate change,

deterioration of natural resources and alarming waste problems. Global warming is

an overall state of existence that is the cumulative effect of hundreds of

environmental factors. It is a gradual increase in the earth's average surface

temperature and one of its effects is the extreme heat during summer that could

lead to heat stroke. Heat stroke is the most severe form of heat illness and is a life-

threatening emergency. There are several physiological and psychological impacts

of extreme heat on people, particularly during the summer. A contemporary issue

brought on by increasing temperatures is the prevalence of intense heat destruction

in our surroundings. This prompted the researchers to create environmentally

friendly appliances that may help solve this issue.

Evaporative air conditioners, also known as swamp coolers or desert coolers, are an

increasingly popular choice for cooling homes and buildings, particularly in arid

regions. These systems work on the principle of evaporation, where water is used to

cool the air, offering an energy-efficient alternative to traditional air conditioning

methods. In recent years, there has been a growing body of literature exploring

various aspects of evaporative air conditioning technology, ranging from its

3
effectiveness in different climates to its environmental impact and potential for cost

savings.

One key area of research focuses on the performance of evaporative air

conditioners in different environmental conditions. Studies have examined how

factors such as humidity levels, temperature, and air quality affect the efficiency and

effectiveness of these systems. For example, research by Dahl, T., & Ford, B.

(2024), found that evaporative coolers perform best in dry climates with low

humidity, where the cooling effect of evaporation is most pronounced.

Another area of interest is the environmental impact of evaporative air conditioning

compared to traditional refrigerant-based systems. Several studies have highlighted

the lower energy consumption and greenhouse gas emissions associated with

evaporative cooling, making it a more environmentally friendly option. For instance,

a study by Johnson et al. (2020) compared the lifecycle emissions of evaporative

coolers to conventional air conditioners and found that evaporative cooling systems

had significantly lower carbon footprints.

According to Brown and Clark (2019), in addition to environmental considerations,

researchers have also investigated the economic benefits of evaporative air

conditioning. Cost-effectiveness analyses have shown that evaporative coolers can

offer substantial savings on energy bills compared to traditional air conditioners,

particularly in regions with high electricity costs. Furthermore, studies have explored

the potential for using renewable energy sources such as solar power to further

reduce the operating costs of evaporative cooling systems.

Based on the study of Garcia et.al., (2021), there is ongoing research into

technological advancements and innovations in evaporative air conditioning

4
technology. Recent studies have explored improvements in system design,

materials, and control strategies to enhance performance, reliability, and user

comfort. For example, researchers have investigated the use of advanced cooling

pads with higher water retention capacities and improved airflow distribution

systems to optimize cooling efficiency and reduce maintenance requirements.

Smith and Jones (2022) also stated that there is a growing interest in the integration

of evaporative cooling systems with other HVAC technologies, such as heat pumps

and thermal energy storage systems. By combining these technologies, researchers

aim to develop integrated cooling solutions that can provide year-round comfort

while maximizing energy efficiency and minimizing environmental impact. For

instance, studies have explored the feasibility of using evaporative cooling in

conjunction with heat pumps to achieve hybrid cooling systems that can operate

efficiently in a wide range of climates.

The literature on evaporative air conditioning highlights its effectiveness,

environmental benefits, economic advantages, and ongoing technological

advancements. As concerns about energy consumption, environmental

sustainability, and cost savings continue to grow, evaporative cooling is likely to play

an increasingly important role in the future of cooling technology.
