Using a variety of methods, heating, ventilation, and air conditioning (HVAC) regulates the temperature, humidity, and air quality in a closed environment. Its objective is to offer suitable indoor air quality and thermal comfort. Mechanical engineering's subfield of HVAC system design is founded on the laws of thermodynamics, fluid mechanics, and heat transport. Sometimes the field's acronym for "refrigeration" is added as HVAC & R or HVAC R.

In residential structures like single-family homes, apartment complexes, hotels, and senior living facilities, as well as in medium- to large industrial and office buildings like skyscrapers and hospitals, as well as in transportation like cars, trains, airplanes, ships, and submarines, as well as in marine environments where safe and healthy building conditions are regulated with respect to temperature and humidity using outside air, HVAC systems play an important role.

In this Book we will discuss the most used equipment in the HVAC Industry, enjoy and share.
