Pre-Requisite Knowledge

Satisfactory completion of level 3 modules for BEng Building Services Engineering or equivalent

Summary of Content

This module develops the students knowledge in the crucial areas of heating and air-conditioning and follows on in a logical progression from the similarly named SD3 level subject. Additional material of a more practical nature is also included on refrigeration. The module content taught here gives the student a detailed expertise of current design practice in these subject areas.

Syllabus

The taught syllabus will cover the following areas: Air Conditioning: Perimeter induction systems. Changeover and non-changeover systems. Two pipe and four pipe systems. Variable air volume systems. Terminal reheat. Fan-assisted systems. VRV systems. Control strategies for the above systems. Load diagrams and plant operating charts for air conditioning systems. Summer temperatures in buildings. Admittance principle. Cooling load calculations. Refrigeration: Types, application and performance of all major plant items. Description and application of practical cycles - cascade, compound, liquid suction heat exchangers. Matching and selection of cycle components. Control methods. Heat Exchangers: Performance design of a variety of heat exchanger configurations, including cross-flow types and tube banks. LMTD and correction factor methods. Effectiveness and NTU methods. Applications to heat recovery and cooling systems.

Learning Outcomes

The Engineering Benchmarks A2,A7,B1,B2,B3,B5,B6,B7,C1 and C4 as specified in the BEng Building Services Engineering Programme Specification Document apply to this module.On completion of this module the student should be able to:- Design and understand the operation of perimeter induction and variable air volume air-conditioning systems (B5,B7,C4)- Construct load and plant operating diagrams for an air conditioning system (A7,B3)- Understand the admittance principle and be able to apply it to assess the cooling load for an air conditioning system (A2,C1,B7)- Evaluate the performance of a range of types of heat excahnger designs, identify appropriate applications and apply/analyse these as heat recovery applications within buildings (A2,A4,B1,B3,B5,C1,C4)- Select, match and size individual refrigeration plant items to provide an overall system to satisfy a particular requirement (A7,B2,B5,C4)

Teaching / Learning Strategy

The module will be taught with an appropriate balance of lecture and tutorial material to support design for heating and air conditioning. The course will be supported with a comprehensive set of course notes to enable students to study effectively by themselves. Learning and teaching strategies will be developed and implemented, appropriate to students' needs, to enable all students to participate fully in the programme.

Transferrable Skills

The Engineering Benchmarks D1,D2,D4,D5,D6 and D8 for transferable skills as specified in the BEng Building Services Engineering Programme Specification Document apply to this module. The student should gain knowledge very relevant to current practice in this discipline. As well as developing the skills for problem solving, the ability to apply a systematic and thorough approach and the skills necessary for the presentation of technical material in a clear and appropriate form, the student should also gain specialist knowledge making him/her an expert in this subject area.
