Experimental Study of Passive Cooling Performance of the Room Using Solar Collectors and Underground Heat Exchange Equipment

Introduction

In the current era of technological development, efforts to save energy are the main focus in many countries. One innovative method to achieve this goal is to apply passive cooling in the interior space. Passive cooling is a method of cooling a building or room without the use of mechanical systems, such as air conditioning. Instead, it relies on natural processes to cool the space. This can include the use of solar collectors, underground heat exchangers, and other innovative technologies.

The Role of Solar Collectors in Passive Cooling

Solar collectors are a key component of passive cooling systems. They work by capturing sunlight and turning it into heat, which is then used to improve the efficiency of the cooling system. In this experiment, the use of solar collectors was combined with underground heat exchangers (EAHE - Earth Air Heat Exchanger) to create a highly efficient passive cooling system. The results showed that the EAHE efficiency combined with solar collectors reached 83.62%. Conversely, Eahe efficiency without solar collectors only reached 74.9%. In addition, the efficiency of the solar collector itself is recorded at 74.18%. With a total cooling capacity reaching 24,4015 W, this method shows a promising potential for use in a passive cooling system.

The Benefits of Underground Heat Exchangers

Underground heat exchangers (EAHE) serve to stabilize the temperature of the air entering the room, so as to improve the quality of the coolant produced. Technically, Eahe functions to exchange heat between outside air and soil, which has a relatively stable temperature throughout the year. By flowing outside air through a buried channel in the ground, the air can be cooled before entering the room. The advantage of this method lies in its ability to reduce the necessary cooling loads, and increase thermal comfort in the room.

Data Analysis and Results

Data analysis shows that the combination of solar collectors and eahe produces more efficient performance compared to systems that do not use solar collectors. This indicates that innovation in the passive cooling system can contribute significantly to energy savings and efficiency of resource use. The results of this experiment demonstrate the potential of passive cooling systems to reduce energy consumption and create a more sustainable environment.

The Importance of Passive Cooling in a Sustainable Future

It is essential to note that high efficiency not only provides benefits to the individual level, but also contributes to global efforts to reduce carbon traces. By improving the performance of a passive cooling system using environmentally friendly technology, we can create a more sustainable environment and reduce dependence on fossil energy. With this promising result, it is crucial for researchers and policy makers to explore further application of the passive cooling method on various scales, both in residential and commercial buildings.

Conclusion

In conclusion, the experimental study of passive cooling performance of the room using solar collectors and underground heat exchange equipment has shown promising results. The combination of solar collectors and eahe produces more efficient performance compared to systems that do not use solar collectors. This indicates that innovation in the passive cooling system can contribute significantly to energy savings and efficiency of resource use. As we move forward in our efforts to create a more sustainable future, it is essential to explore further application of the passive cooling method on various scales, both in residential and commercial buildings.
