Unit 10 Principles of Ventilation & Air-conditioning Design & Installation - Higher National Certificate Construction and the Built Environment

Assignment - System Design and Cooling Load Analysis

Learning Outcome 1: Identify pre-design information required for a non-domestic ventilation and air conditioning system.

Learning Outcome 2: Analyse cooling loads for non-domestic buildings.

Learning Outcome 3: Present a design for a non-domestic ventilation system and air-conditioning system for a given building type.

Learning Outcome 4: Justify the selection of non-domestic ventilation and air conditioning components and an installation strategy.

Assignment Brief:

Task 1:

You have been hired by a local Air-Conditioning Services firm, as an assistant to the building services engineer. The firm has been appointed to manage the design and installation of a new cooling system for a small commercial building. Your employer has tasked you with identifying and preparing an initial report on the pre-design information needed and cooling loads required for the building.

Your report should include:
• an overview of the design process for a cooling system
• a review of the information that will be required for a cooling system design brief
• calculations to support the design of a system, including heat gain, cooling load and peak temperatures analysis of health and safety legislation related to air-conditioning systems.

Task 2:
Having prepared a report on the design information and cooling loads, your employer would now like you to undertake the design of the system and selection of necessary plant/components for a small commercial building.
Based on pre-design information and cooling load analysis (Task 1) and drawings, in your report you are expected to compare and evaluate sustainable options for inclusion in a ventilation and air conditioning strategy for a given building type include:
• prepare a design for the ventilation and air-conditioning systems, comparing different alternatives to arrive at a design
• consider how to reduce the total cooling load in order to make the system more sustainable
• specify the requisite plant/components for the ventilation and air-conditioning systems, including consideration of ducting sizes and their effect on the systems.
