Keeping Your Cool
As temperatures outside rise, indoor thermostats often respond by calling for cooler air. This ability to control the indoor environment helps people be more comfortable. It protects infants, children, medically vulnerable individuals, and the elderly from heat-related illnesses. It enables workers to be more productive.
In our current age, air conditioning is something many folks take for granted. To address this blasé attitude, the heating, ventilation, and air conditioning (HVAC) industry observes Air Conditioning Appreciation Days every year from July 3 to August 15.
But how does one show appreciation to an air conditioner? One way is to learn how it works and how it all began.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) offers a simplified explanation: A chemical (called the refrigerant) circulates through a closed system that includes three main components where the refrigerant is compressed, condensed, and evaporated. During the process, the refrigerant undergoes changes in pressure and temperature. This enables indoor heat to be absorbed and transferred to the outdoor environment.
