The Evolution of Air Conditioning in Kinston, NC
As summer’s scorching temperatures and oppressive humidity envelops Kinston, NC, many residents rely on air conditioners for relief. These complex electromechanical systems represent the end product of decades of engineering advancements in controls, energy efficiency, thermodynamics and cooling. The following unveils the evolution of air conditioning systems, exploring the integration of technology, engineering and environmental consciousness.
Early Conceptions of Cooling
In the 1840s, Dr. John Gorrie proposed the idea of cooling cities to protect residents from scorching temperatures. His early system required shipping ice from northern lakes, inspiring him to develop a machine powered by various methods to create ice. Though unsuccessful commercially, Gorrie’s invention set the groundwork for modern air conditioning and refrigeration.
The Birth of Modern Air Conditioning
In 1902, an ingenious engineer named Willis Haviland Carrier created the first modern air conditioner. To address a printing plant’s humidity issue in Brooklyn, NY, Carrier drew from previous mechanical refrigeration concepts. His innovative system passed air through water-filled coils, cooling the air and regulating room humidity by removing moisture.
His company developed an air conditioner featuring mechanical controls, a belt-driven condensing unit, an evaporator coil and a blower in 1933. This innovation set the standard for air cooling systems in the rapidly growing U.S. market. Today, air conditioners still rely on the fundamental principles of this AC system, but they have evolved with improvements in materials, energy efficiency electronic sensors, vapor compression and diagnostics.
Advancements in Residential Air Conditioning
In 1929, an appliance company introduced a small split-system room cooler for home use. Although the system resembled a radio cabinet, it was heavy, expensive and needed a separate condensing unit. Frank Faust of General Electric later improved the design with a self-contained room cooler, inspiring the production of 32 similar prototypes from 1930 to 1931.
In 1932, H.H. Schultz and J.Q. Sherman patented a window air conditioning unit, but its high cost limited its popularity. Engineer Henry Galson later created a smaller, more affordable version, leading to widespread adoption by 1947, providing homeowners with accessible air conditioning.
Air Conditioning’s Impact on Public Spaces
Movie theaters were among the first to adopt air conditioning technology. However, early cooling systems in theaters modified heating systems with refrigeration equipment, distributing cold air through floor vents and causing discomfort due to uneven temperatures. In 1922, a company installed a well-designed cooling system at the Los Angeles Metropolitan Theater, improving humidity control and comfort by pumping cool air through higher vents.
In May 1922, it installed a newly designed centrifugal chiller system at the Rivoli Theater in New York. This innovative design featured fewer moving parts and compressor stages, enhancing reliability and reducing large-scale air conditioning costs. Consequently, the use of air conditioners expanded widely throughout the country.
Energy Efficiency and Environmental Concerns
In the latter part of the 20th century, there was growing awareness of energy consumption and its environmental impact. Lawmakers enacted energy reduction laws, leading to the formation of the Appliance and Equipment Standards Program within the Department of Energy. The program helps establish a unified federal energy efficiency standard for air conditioner manufacturers, replacing state-specific standards.
Over time, AC manufacturers have achieved compliance with the regulations by successfully raising the seasonal energy efficiency ratio (SEER) to 16 or 18, surpassing the Department of Energy’s efficiency standards. This aids the environment and allows customers to save on energy costs.
Advancements in Smart Air Conditioning
Certain air conditioning manufacturers are pushing the boundaries of the standard wall thermostat to further reduce energy consumption. They are developing advanced microprocessor-based diagnostic and control kits that automate the operation of compressors and airflow systems.
For instance, the Trane ComfortLink II remote thermostat empowers homeowners to remotely control AC functions and settings using computers and smartphones. It also sends text and email notifications for filter replacements and AC repairs.
The Future of Air Conditioning
Various AC manufacturers are making significant progress in developing smart technologies that seamlessly integrate their systems with the national electric grid. This integration will facilitate regulation based on geographical and changing weather conditions. Consequently, the potential for grid interoperability could steer air conditioning research towards embracing fully variable speed systems, resulting in even more substantial reductions in energy consumption. Bryant is an industry leader, offering a wide selection of energy-efficient, variable-speed air conditioners.
