Here we are going to know about HVAC Systems. These systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, locations and distribution. Primary HVAC includes heating equipment, ventilation equipment and cooling or air conditioning equipment. Central HVAC system locate away from buildings in a central equipment room and delivers the conditioned air by a delivery ductwork system. Central HVAC systems contain all air, air-water, all-water systems. Local HVAC systems can located inside a conditioned zone and no requirement for ductwork. Local systems include local heating, local air conditioning, local ventilation and split systems.

Introduction of HVAC Systems

Heating, Ventilation and Air Conditioning System is designed to get the climate needs of comfort of occupants & process. HVAC Systems are used in different types of buildings such as industrial, commercial, residential & institutional. The main purpose of HVAC system is to satisfy the thermal comfort of occupants by adjusting & changing the outdoor air conditions. The selection of hvac systems in a given building depends on the climate, age of building, owner of building and designer of project, budget and design of building. HVAC Systems can be classified according to necessary processes and distribution processes. Such as: Heating Process, Cooling Process, Ventilation Process, Humidification and Dehumidification Process. By using suitable equipment we can achieve these processes. Such as: Heating Systems, Cooling Systems, Ventilation Fans & Dehumidifiers. The HVAC System needs distribution systems to deliver the required amount of air. The distribution system varies according to refrigerant type and delivering method such as: Air Handling Equipment, Fan Coils, Air Ducts & Water Pipes.

HVAC System Selection Process

System selection depends upon three factors including building construction, climate conditions and owner desire. The design engineer is responsible for considering various systems and recommending more than one systems to meet the goal and satisfy the owner of the building. Some criteria can be considered such as climate change, building capacity, spatial requirements, cost, life cycle, reliability and flexibility.

Classification of HVAC Systems

The major classification of hvac system is central HVAC system and Local HVAC system. Types of a system depend upon addressing the primary equipment location to be centralized as conditioning entire building as a whole unit or local as separately conditioning a specific zone as a part of a building. Therefore, the air and water distribution system should be designed based on system classification and the location of primary equipment.

Temperature, Humidity & Space PressureFulfilling any or all design parametersFulfilling any or all design parameters
Capacity RequirementsConsidering HVAC diversity factors to reduce the installed equipment capacity, Significant first cost and operating costMaximum capacity is required for each equipment, Equipment sizing diversity is limited
RedundancyStandby equipment is accommodated for troubleshooting and maintenance,No backup or standby equipment
Special RequirementsAn equipment room is located remote from the building, Installing secondary equipment for air and water distributionPossible of no equipment room is needed, Equipment may be located on the roof and the ground adjacent to the building
First CostHigh capital costAffordable capital cost
Operating costMore significantLess significant
Maintenance costLow costHigh cost
ReliabilityReliable for long period useReliable for short period use
FlexibilityMore flexible because of backup equipmentLess flexible because there is backup unit
