What is HVAC?

HVAC is an acronym for Heating, Ventilation and Air Conditioning, which means heating, ventilation and air conditioning. It stands for both the above-mentioned disciplines and technologies, as well as the industries and trades involved in the above-mentioned disciplines and technologies. HVAC also refers to an applied discipline, which has a wide range of influence in the world of architectural design and engineering as well as manufacturing, and there are HVAC associations in various countries, and the HVAC branch of the Chinese Architectural Association is the official representative body of China. Heat transfer, engineering thermodynamics and fluid mechanics are its basic theoretical foundation, and its research and development direction is to provide a more comfortable working and living environment for human beings.

An air conditioning system is a control system that includes temperature, humidity, air clarity, and air circulation, and is called HVAC. air conditioning supplies cold air, warm air, or dehumidification, all of which work on a similar principle, using refrigerant evaporation or condensation under the action of a compressor, which triggers evaporation or condensation of the surrounding air to change the temperature and humidity. It is worth noting that the "heater" is a rare and excellent device with a thermal efficiency greater than 1 (if the 'greenhouse effect' is not taken into account). This makes it much less constructive for subtropical regions than for temperate regions.

In simple terms HVAC can be thought of as a heating, ventilation and air conditioning system, Ningbo Sonia Intelligent Optoelectronics Co.
