HVAC Course Details

• Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of Mechanical Engineering, based on the principles of Thermodynamics, Fluid Mechanics, and Heat Transfer.
• It has a very huge scope it mainly used in;
• Industries where constant temperature and humidity levels are needed for production. For example: pharmaceuticals industries, food industries, etc.
• In buildings for humidifying and dehumidifying, cooling/heating the rooms as per requirement. For example: Malls, hospitals, hotels, etc.

Purpose of HVAC System

• Temperature can be maintained (24 degrees Celsius for Human Comfort).
• Humidity can be maintained.
• Maintains proper Filtration of Air
• Atmospheric Air (Fresh Air) can be added and remove odor from the room.
• To hold Air Contamination within acceptable limits.

Various equipment used to maintain HVAC systems are:

• Chiller
• Pumps
• Boilers
• Humidifier/Dehumidifier
• AHU (Air handling units)

HVAC system mainly works on the following Cycles

• VARS Cycle: Vapor Absorption Refrigeration Cycle.
• VCRS Cycle: Vapor Compression Refrigeration Cycle.
