The aim of this unit is to review the operation and design of heating, ventilation and air-conditioning (HVAC) systema typically found in the built environment.
HVAC systems can use a cutting-edge technology for maintaining comfort in both indoor and outdoor environments for building occupants. HVAC systems are made to offer adequate indoor air quality and thermal comfort. Therefore, HVAC systems are a crucial factor to take into account when designing residential, commercial, and institutional buildings.
Human being spends significant periods of their time in the built-environment and HVAC systems facilitate comfortable and healthy living and working environments. The ventilation system changes or replaces the air in a room to manage temperature and remove moisture, odour, smoke, etc., while the air conditioner offers cooling and humidity control. The heating system creates heat for the building. Reduced energy costs, improved temperature variability, cleaner air, remote access, and other advantages may all be attained with efficient HVAC systems.
This unit will cover key HVAC design parameters, components of HVAC, equipment sizing, specifications of non-domestic heating, ventilation (Natural and Mechanical), and calculations of heating and cooling load.
On completion of this unit, students will understand the principles of operation of a HVAC system and be able to understand its requirements with respect to sustainability.
During this unit, you will cover the below four learning outcomes:
LO1: The learner will be able to describe the components of typical HVAC systems and their function.
LO2: The learner will be able to explore the statutory requirements of HVAC systems.
LO3: The learner will be able to evaluate heating and cooling loads.
LO4: The learner will be able to analyse the sustainable options for HVAC design.
