3. Types of Air Conditioning Units: a) Window Units: These air conditioners are compact, economical, and suitable for single rooms or small spaces. Mounted on windows, they consist of a single unit that contains all components. b) Split Systems: Split air conditioning units consist of an indoor unit that typically contains the evaporator and a compressor unit located outside the building. These systems are ideal for larger spaces or buildings.

c) Centralized Systems: Centralized air conditioning systems are designed for large commercial or residential spaces. These units cool multiple rooms simultaneously, providing efficient and uniform cooling throughout the area. 3. Design Considerations: 3.1. Sizing: Proper sizing of duct systems is crucial to ensure a balanced airflow and adequate delivery of conditioned air throughout the building. 3.2. Pressure Drop: Duct layouts must be designed to minimize pressure drop, ensuring an efficient HVAC system and reducing energy consumption.

3.3. Insulation: Duct insulation reduces heat gain or loss, preventing energy wastage and condensation problems. 3.4. Acoustic Considerations: Adequate measures should be taken to minimize noise from airflows within duct systems to enhance occupant comfort. 3.5. Airflow Distribution: Proper distribution of air supply and return vents ensures uniform comfort levels in each space, avoiding hot and cold spots. 2. Components of Duct Systems: 2.1. Supply Ducts: These deliver conditioned air from the HVAC unit to different rooms or zones within a building.

2.2. Return Ducts: Responsible for collecting and channeling air back to the HVAC unit for reconditioning. 2.3. Branch Ducts: These connect the main supply ducts to individual supply registers or diffusers in each room. 2.4. Plenums: They act as distribution points to direct airflow to multiple branch ducts or serve as transitions between different duct sections. 2.5. Registers and Diffusers: These components facilitate the delivery of conditioned air into occupied spaces while enabling adjustment of airflow volume and direction.

2.2 Mechanical Ventilation: Mechanical ventilation systems utilize mechanical devices like fans, blowers, and exhaust systems to supply and circulate fresh air. It helps maintain consistent airflow rates and enables better control over IAQ compared to natural ventilation. Mechanical ventilation can be further classified into: This case study demonstrates the successful installation of a new air conditioning unit in the XYZ Corporation’s commercial building. The new system exhibited enhanced cooling efficiency, resulting in improved indoor temperature control and increased employee comfort.

The reduction in energy consumption not only provided substantial cost savings but also assisted the corporation in reducing its environmental impact. 1. Purpose of Ventilation Systems: The primary purpose of ventilation systems is to remove stale air and pollutants from indoor spaces while simultaneously supplying fresh outside air. This exchange helps to dilute indoor pollutants, control temperature and humidity levels, and ensure a healthy and comfortable environment.

Additionally, ventilation systems play a crucial role in reducing the risk of airborne diseases and improving overall productivity. – Supply-only Ventilation: Supply-only systems introduce fresh air into indoor spaces using fans or blowers, while stale air is expelled through natural leaks or exhaust vents. This system is frequently implemented in bedrooms and living areas. 4. Factors to Consider for System Selection: a) Building Type and Occupancy: The ventilation system should be matched with the specific requirements of the building, such as the number of occupants, size, and usage.

The commercial building under consideration is a large office complex located in a bustling metropolitan area. The pre-existing air conditioning system consisted of outdated equipment, resulting in high energy consumption, inefficient cooling, and frequent breakdowns. In response to mounting complaints from tenants alongside the need to align with sustainability goals, the facility management team decided to invest in a state-of-the-art air conditioning system. 2. Types of Ventilation Systems: a) Natural Ventilation: Natural ventilation relies on natural forces, such as wind and buoyancy, to create airflow within a building.

It involves the strategic placement of windows, vents, and openings to promote air circulation. While cost-effective and energy-efficient, natural ventilation is highly dependent on external weather conditions and requires careful building design. 3. Benefits of Ventilation Systems: a) Improved Indoor Air Quality (IAQ): Ventilation systems remove pollutants, including dust, allergens, VOCs (volatile organic compounds), and odors from indoor environments. This results in improved IAQ, preventing health issues such as allergies, respiratory problems, and sick building syndrome.
