Introduction to HVACR (Book Version)
Introduction to HVACR provides basic information about heating, ventilating, air conditioning, and refrigeration systems (commonly referred to by the acronym HVACR). These systems handle air quality, temperature control, humidity regulation, heating, refrigeration, and other aspects of climate control within buildings in a repetitive cycle. Like plumbing systems, the manufacturing, installation, and operation of heating, ventilating, and cooling systems are based on codes, engineering, and science. Heating, ventilation, and air conditioning functions—the “HVAC” part of the acronym—are responsible for human comfort inside buildings. In modern homes and other buildings, these functions are often combined into one system. Refrigeration (the “R” part of the acronym) uses a technology similar to air conditioning to keep our food and some manufacturing processes cool. Together, HVACR systems are what keep people warm in the winter and cool in the summer, provide fresh air for them to breath, and allow them to store food and beverages for long periods. This course includes definitions of common industry terms and descriptions of the major types of residential and light commercial HVACR systems. It also provides information that will help employees to better assist their customers.
