Initial Assessment and Maintenance Plan (300 words): To begin the maintenance process, a thorough assessment of the HVAC system was conducted by an experienced team of HVAC professionals. The assessment aimed to identify any mechanical faults, operational inefficiencies, and inadequacies that may be contributing to the building's HVAC challenges. Introduction (150 words): In today's commercial and residential buildings, heating, ventilation, and air conditioning (HVAC) systems play a vital role in maintaining comfortable and healthy indoor environments.

However, the optimal performance of HVAC equipment depends on regular maintenance to ensure effective operation, energy efficiency, and cost-effectiveness. This case study aims to analyze the positive impact of HVAC maintenance on a large commercial building in terms of improved system performance, energy savings, increased occupant comfort, and cost reduction. 1. Components of a Rooftop Unit: Rooftop units consist of several essential components, each playing a vital role in the system's overall functionality.

These components include: a) Compressor: The compressor is responsible for pressurizing the refrigerant, enabling it to absorb and release heat efficiently. b) Condenser: This component facilitates the release of heat from the refrigerant, converting it from a high-pressure gas to a high-pressure liquid. c) Evaporator: The evaporator helps absorb heat from the indoor air, turning the refrigerant from a low-pressure liquid to a low-pressure gas.

d) Blower: The blower is in charge of distributing conditioned air throughout the building, ensuring proper ventilation and temperature control. e) Control System: The control system regulates and monitors the operation of the rooftop unit, providing user-friendly interfaces for temperature adjustments and system diagnostics. 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: 1. Cleaning and Filtration: The AHUs and air conditioning units were cleaned meticulously to remove accumulated dust, debris, and contaminants. Additionally, the air filters were replaced, ensuring improved indoor air quality, preventing HVAC blockages, and promoting the longevity of the equipment. Case Study Description (400 words): The case study focuses on a large commercial building spanning 10 floors, housing various businesses and offices.

The HVAC system in this building consisted of two central air handling units (AHUs), ten air conditioning units, and an extensive ductwork network. Over the years, HVAC complaints, increased energy bills, and inconsistent temperatures were reported by occupants, indicating the need for a comprehensive maintenance approach to address these issues. Conclusion: Rooftop units are versatile HVAC systems that provide heating, cooling, ventilation, and air filtration in commercial and industrial buildings.

Their modular design, scalability, space-saving nature, and energy-efficient features make them a popular choice for many applications. Careful consideration regarding installation, maintenance accessibility, and zoning requirements is crucial to ensure optimal performance and long-term reliability. With their numerous advantages, rooftop units continue to be a reliable and effective solution for maintaining desired indoor conditions in various settings.

3.3 Enhanced Building Performance: Proper ventilation maintains an optimal balance between humidity and temperature, increasing occupant comfort and productivity. Additionally, preventing moisture buildup via ventilation systems protects the building's structural integrity, reducing the likelihood of mold growth or material degradation. 2.2.3 Balanced Ventilation: Balanced ventilation combines both exhaust and supply ventilation systems.

It ensures a continuous airflow by introducing fresh air and removing stale air simultaneously. This equilibrium helps maintain IAQ while regulating pressure differences within the building. Introduction: A rooftop unit (RTU), also known as a rooftop package unit, is an HVAC system capable of providing heating, ventilation, and air conditioning in commercial and industrial buildings. It is installed on the roof of a building, offering numerous advantages such as scalability, space conservation, and reduced noise levels within the occupied areas.

This report aims to delve into the various components, functions, benefits, and considerations associated with rooftop units.
