The task of this HVAC system will be to either change the air flow in any space to control the temperature or eliminate any combination of moisture, odor, smoke, heat, dust, or is bacteria inside the air or CO2 and replenish oxygen.
Mission: Provide airflow according to pre-installation requirements and humidity for all or part of the building. Normally, air-conditioned buildings often have closed doors, opening windows will reduce the cooling effect from the air-conditioning system.
Air conditioning and refrigeration are usually created by removing heat from inside the system. Air temperature can be removed by radiation, convection or transmission through a chiller. Some vehicles help cold transmission such as water, air, ice, chemicals or collectively called refrigerants. These refrigerants are used in heat pump systems, in which compressors are used to control cooling cycles by thermodynamics, or in a cooling system by using pumps to transport transfer a refrigerant (usually water or a glycol mixture).
PROCESS OF HVAC SYSTEM.
Supply Air: Supply air, here includes cold air and hot air.
Return Air: Bring air back and forth.
Exhaust: Discharge of air that is not clean to the outside, usually discharged in the restroom.
SIGNS OF HVAC SYSTEM.
The most visible sign when having an HVAC system is the pipes running through the building. Currently, HVAC pipes often have 3 different morphologies which are Square (Rect), Round (Round) and Oval.
However, for ease of manufacture and construction, people often use two types of pipes that are square and round.
For a M&E contractor, the design and installation of HVAC systems for buildings is very important. Most of the new electrical and mechanical construction projects or maintenance and renovation projects are related to the HVAC system. Therefore, investors should look to professional mechanical and electrical contractors.
