MODULE 1 - INTRODUCTION TO HVAC
HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems used to control and regulate the temperature, humidity, and air quality in buildings and other indoor spaces. HVAC systems are essential for maintaining comfortable and healthy living and working environments.
The heating component of HVAC systems typically involves the use of boilers, furnaces, and heat pumps to produce warmth, while the ventilation component involves the circulation and exchange of air within a space. Air conditioning systems are used to cool indoor spaces and can also be used to control humidity levels.
HVAC systems are designed to provide a comfortable and healthy indoor environment by controlling temperature, humidity, and air quality. Properly designed and maintained HVAC systems can also reduce energy consumption and costs associated with heating and cooling. The design and installation of HVAC systems require specialized knowledge and expertise in fields such as mechanical engineering, electrical engineering, and construction. HVAC professionals must also be knowledgeable about building codes, energy efficiency standards, and environmental regulations.

MODULE 2 — HVAC DESIGN
HVAC (Heating, Ventilation, and Air Conditioning) design is the process of designing and engineering a system that provides thermal comfort and acceptable indoor air quality for a building’s occupants. HVAC design involves the selection and sizing of equipment, ductwork, and controls, as well as the layout of air distribution systems and placement of equipment.
The first step in HVAC design is determining the heating and cooling load for the building. This involves calculating the amount of heat gained or lost through the building envelope, as well as internal heat sources such as people, lighting, and equipment. The heating and cooling load calculation is used to determine the size and capacity of the heating and cooling equipment required for the building.
Once the heating and cooling load has been calculated, the HVAC designer must select the appropriate equipment, such as furnaces, boilers, air conditioners, and heat pumps, and design the air distribution system. This includes selecting the size and layout of ductwork, grilles, and registers, and determining the location of the HVAC equipment. The HVAC designer must also consider the indoor air quality requirements of the building and design the ventilation system accordingly.
This includes selecting the appropriate air filtration and purification systems, and determining the amount of fresh air that needs to be supplied to the building. Overall, HVAC design is a complex process that requires careful consideration of many factors, including the size and layout of the building, the climate, the indoor air quality requirements, and the energy efficiency goals of the project. A well-designed HVAC system can improve occupant comfort, health, and productivity while reducing energy costs and environmental impact.

MODULE 3 — HVAC DUCT DESIGNING
Designing an HVAC duct system involves determining the appropriate duct size, layout, and insulation to ensure efficient heating and cooling distribution throughout a building. Here are some steps to follow when designing an HVAC duct system:
Calculate the heating and cooling loads: The first step in designing an HVAC duct system is to calculate the heating and cooling loads for each room or area in the building. This involves determining the heat gain or loss from sources such as lighting, appliances, and people, as well as the heat transfer through the building envelope.
Determine the required air flow: Based on the heating and cooling loads, you can then determine the required air flow for each room or area. This will depend on factors such as room size, ceiling height, and the number of occupants.
Select the appropriate duct material and size: The next step is to select the appropriate duct material and size for each room or area. This will depend on the required air flow, as well as the distance between the HVAC unit and the room or area.
Design the duct layout: Once the appropriate duct size and material have been selected, you can then design the layout of the duct system. This involves determining the most efficient path for the ducts to take, as well as any necessary turns or bends.
Insulate the ducts: Finally, you should insulate the ducts to prevent heat loss or gain and ensure efficient heating and cooling distribution.
It’s important to note that designing an HVAC duct system is a complex process that requires expertise and experience. It’s best to consult with a professional HVAC contractor or engineer to ensure that your system is designed correctly and efficiently.

MODULE 5 — EXHAUST AIR SYSTEM
An exhaust air system is a type of ventilation system designed to remove stale or contaminated air from an indoor space and replace it with fresh outdoor air. The system uses a series of ducts, fans, and vents to circulate air throughout the building and remove pollutants, such as carbon dioxide, moisture, and odors.
Exhaust air systems are commonly used in commercial and industrial settings, such as factories, laboratories, and hospitals, where there is a high level of pollutants or contaminants in the air. They are also used in residential settings, such as kitchens and bathrooms, to remove moisture and unpleasant odors.
In an exhaust air system, the air is typically drawn out of the building through one or more exhaust vents, which are usually located in the ceiling or roof. The air is then forced through a series of ducts and out into the environment. To replace the exhausted air, fresh outdoor air is drawn into the building through intake vents or through a dedicated outdoor air system (DOAS).
The design and implementation of an exhaust air system can vary depending on the specific needs and requirements of the building or space. It is important to ensure that the system is properly designed, installed, and maintained to ensure optimal performance and efficiency.
