The 10 most important parts of HVAC system?
HVAC System:-
The full form of HVAC is Heating Ventilation and Air conditioning. HVAC plays a very precious role for maintaining indoor environment conditions. HVAC system is a technology used to maintain indoor air temperature, humidity, and air quantity. It helps to keeping us from warm during the summer season and keeping us from cold during the winter season.
The parts of HVAC system are:-
1. AHU
2. Compressor
3. Condenser
4. Thermal expansion valve
5. Terminal units
6. Chiller
7. Duct system
8. Electrical panel
9. BMS system
10. Heating system
1. AHU
AHU stand for air handling unit. In HVAC system AHU is main parts of whole system.
AHU is an air handling machine, which is used to regulate or handle or circulate air to different areas. AHU having different chamber or compartments like Mixing chamber, filter section, cooling coil chamber, heater section, motor section, UV light section.
Air is from area is suck through duct and supplied to same area through supply air duct. When air enter in to ahu through return air duct the air is mixed with fresh air, then passed to filter section, after filtration it passed to cooling coil section to cool, here some moisture is also removed from air, then passed to heater section for the addition of sensible heat. After adding heat, it passed to motor section and that motor is pull air through fine filtration to supply air duct.
2. Compressor ( ODU )
Compressor is the part of outdoor unit. In HVAC system compressor is used for the compression of refrigerant gas. The compressor also helps the gas to circulate through pipe. Compressors help to maintain the motion of refrigerant gas.
3. Condensor
Compressor is the part of outdoor unit. In HVAC system compressor is used for the compression of refrigerant gas. The compressor also helps the gas to circulate through pipe. Compressors help to maintain the motion of refrigerant gas.
4. Thermal Expansion Valve:-
The thermal expansion valve is part of RAC cycle. It help to modulate the discharge refrigerant gas with the help of suction refrigerant gas temperature. The thermal expansion valve modulate according to the suction temperature.
5. Terminal Units:-
In HVAC system, HEPA filter, diffuser is known as terminal unit. In pharmaceutical sector mainly HEPA filter is used. In non-classified area diffuser is used.
6. Chiller:-
Duct is used in HVAC system to flow air in specific area to get temperature. There are different type of duct is used in HVAC systems. Like Circular duct, rectangular duct, oval shape duct. These all duct is made of GI sheet. The sheet may be 18G, 20G, 22G, 24G etc, depend on client requirements and design.
7. Electrical Panel:-
Electrical panel help to control the whole system by interlocking all unit with AHU. Electrical panel is made of different interlocking and control wiring to interlock complete system.

8. BMS systems:-
The full form of BMS is Building Management system. This system is also known as IBMS means Integrated Building management system.
A complete and well function Building Management System(BMS) can help for energy saving, time saving and also help to analyze specific problems.
A well function Building Management System system can save a lot of energy but turning off of unused machine automatically. You can check each and every room conditions or system condition with the help of you Android mobile or Laptop by accessing it.
This Building Management System system indicates each and every machine with the some special graphics to understand and operate system with Desktop.
