Assignment Task
1. Introduction
During this course you will be required to undertake a major design project. In this project you will design a heating, cooling, and air conditioning (HVAC) system for a building. The design should be based on the geographical characteristics and weather conditions of the buildings location. You will need to first collect some data regarding the building, make several engineering assumptions, develop a mathematical model, and analyse the obtained results. You are not limited a specific type of building and can choose buildings like the northern end of the Engineering Labs-building 27, a complex of offices, School of Engineering- third floor, a section of a hospital, and a multi-story residential or commercial building.
2. Overview
HVAC is the field which encompasses heating, ventilation and air conditioning systems. These are the mechanical systems which manage the environmental comfort of buildings, homes, and living areas. Some of the systems include air conditioning systems, heating systems, and chillers. To design an efficient HVAC system, it is important that engineers understand the concepts of sensible heat and latent heat and their interrelationships. This design project will include the development of a full graphical analysis/simulation to have a deeper understanding on the heating and cooling loads transferred externally and internally. You will learn how to establish the physical characteristics and how HVAC systems may be influenced by the geographical layout. Thermodynamic basic laws and governing mathematical differential equations will be the focus for the basis foundation of the modelling approach.
3. Objectives
Develop engineering design skills by making assumptions, gathering data, building a model, and results analysis
Gaining proficiency in using engineering software by developing a comprehensive model
Have a deeper understanding of the heating and cooling loads in buildings
Understanding the physical characteristics of HVAC systems and how they may be influenced by the geographical layout
4. Load Calculations
The structure and dimensions of the building
Materials used in the building and their properties
Geographical and weather conditions
Design assumptions including the inside temperature for human comfort
Different heat loads/sources inside the building
Model Development for calculation of heating and cooling loads
