What are the main aspects of HVAC?

"HVAC" is the name of the work classification of construction equipment.

HVAC (Heating, Ventilation and Air Conditioning) includes heating, ventilation and air conditioning.

Heating, also known as heating, is to provide loads to buildings according to people's requirements and ensure that the indoor temperature is continuously higher than the external environment. Generally, a radiator or the like is used.

Ventilation: the process of sending air into or out of a room. Replacing the air in a building (called indoor air) with outdoor air (called fresh air or fresh air) is usually divided into natural ventilation and mechanical ventilation.

Air conditioning: (air conditioning)-air conditioning is used to adjust the temperature, humidity, cleanliness and airflow speed in a room or space, and provide enough fresh air for the building environment control system.

Air conditioning is divided into central air conditioning and household unit air conditioning. The biggest feature of central air conditioning is that it can create a comfortable and clean indoor environment. The general split air conditioner at home can only solve the problem of cooling and heating, but can't solve the air humidity and air cleanliness. The air treatment process of central air conditioning has the following processes: first, fresh air is introduced, which can be cooled before filtering, and dust, bacteria, viruses, smoke and dust, or odor can be filtered out after filtering; In addition, a humidifier will be added, which can create a relative humidity of about 40% in our room, so that people will feel very comfortable.
