1. Groundwater use and groundwater air conditioning

This book compares and explains the basic mechanisms, energy efficiency, operating costs, adaptability to installation environments, environmental impact, and maintainability of water-cooled and air-cooled air conditioners. Water-cooled types are highly efficient and economical in the long term, but require a water source and initial investment. Air-cooled types are easy to install but are less efficient. It is important to understand the characteristics of both types and make the appropriate choice based on the usage environment and operating conditions.

This article explains the legal definitions of groundwater and well water, the current state of industrial use, related laws and regulations, and procedures and precautions for use. It also quantitatively analyzes the advantages and disadvantages of groundwater use and introduces environmentally friendly, sustainable methods of use and advanced examples of initiatives. It comprehensively discusses the importance and challenges of groundwater use in aiming to simultaneously reduce costs and environmental impact in factory operations.

Well water air conditioning systems are a technology that utilizes the stable temperature of groundwater to achieve highly efficient heating and cooling. Compared to conventional systems, the COP is two to three times higher, and power consumption can be significantly reduced. Although the initial investment is high, it can be recovered in about five to eight years, and large economic benefits can be expected in the long term. With a low environmental impact, it is attracting attention as a sustainable air conditioning solution.

Water-cooled air conditioners are highly efficient air conditioning systems that utilize the excellent thermal conductivity of water. The main components are a refrigerator, cooling tower, circulation pump, piping system, and indoor unit. They are characterized by high heat exchange efficiency, energy saving, stable performance, and long life. Water quality management, pipe inspection and cleaning, filter management, and cooling tower maintenance are important to maintain the efficiency of the system.

This book provides a comprehensive explanation of the legal requirements for using well water in factories, the permit application process, the design of highly efficient air conditioning systems, water quality management, preventive maintenance, TCO reduction effects, environmental impact reduction, and symbiosis with the local community. It also introduces practical methods for sustainable water resource management and advanced initiatives, and provides a comprehensive explanation of the important points in water resource management in factories, from compliance with laws and regulations to contributions to the local community.

Well water air conditioners are highly efficient air conditioning systems that use groundwater as a heat source. Due to their thermodynamic advantages, they can reduce electricity bills by 30-50% compared to regular air conditioners, and investment can be recovered in 3-5 years. They also have a high environmental impact reduction effect, such as reducing CO2 emissions and fluorocarbon usage, and maintaining groundwater levels, and further efficiency improvements are expected by combining them with IoT technology.

Well water heat pumps are innovative systems that utilize the stable temperature of groundwater to significantly improve the heating efficiency of factories. They have a higher COP than conventional air heat sources and can reduce energy consumption by 30 to 401 TP3T. They offer multiple benefits, including the superiority of water cooling, sustainable water resource management, economic efficiency over the long term, and optimization of energy management throughout the factory.
