This is a comprehensive Course providing a simple understanding of Refrigeration and Air Conditioning fundamentals, applications and terminology. The Course covers SI Units, AC & R heat load calculation, equipment selection, systems, cycles, components and controls, a study of the Vapour Compression Cycle, use of Pressure-Enthalpy Charts, the basis of the Psychrometric Chart and how it can be used for design and problem solving, Refrigerants & the Environment, Single and two-stage Refrigeration, Pipework Layout and Design, Refrigeration Components. Participants are assisted through specially formulated exercises to develop the necessary skills.

The Purpose and Function of Refrigeration. Air Conditioning and the equipment. People, Comfort & Efficiency. Buildings, Offices, Display Cases and Cold Stores. Basic Definitions and SI Units. Pressure, Temperature. Sensible, Latent & Enthalpy; Heat Transfer. Heat Load Calculation for comfort and close control air conditioning.

An overview of key refrigeration cycle components including Compressors, Evaporators, Condensers, Capillary Tubes and Thermostatic Expansion valves. Air & Water Cooled Equipment. Principles of Heat Pumps. Introduction to the Pressure Enthalpy Chart & application for Design, Commissioning & Fault Finding. Single Stage Air Conditioning & Refrigeration Systems. 2 Stage Low Temperature Systems. Introduction to the Properties of Air and Psychrometric Processes. How air is used to transport Sensible & Latent Cooling. Use of key formulae, the structure and application of the Psychrometric Chart. Sensible Heat Ratio of rooms and equipment. System design exercises including Cooling, Heating, Steam & Spray Humidification and Refrigeration & Chemical Dehumidification. Refrigerants & the Environment. Global Warming and the Greenhouse Effect. Properties and comparison of new refrigerants – operating temperatures, pressures and energy consumption. Operators legal obligations under the F Gas Regs.

At the end of the Course, delegates will be able to perform all heat, pressure and power calculations using SI Units; calculate heat gains for comfort & close control air conditioning applications; select appropriate air conditioning and refrigeration equipment to meet the calculated heat gains; enter system operating conditions of plant on the Pressure-Enthalpy Chart; Use and perform calculations on the Pressure-Enthalpy Chart for design, commissioning or fault-finding of systems; Select, design and apply components on single stage and two stage refrigeration and air conditioning systems; Use the Psychrometric Chart for system design calculations in cooling, heating, humidification and dehumidification.

Ideally suited for those with little or no knowledge of the subject. The Course is also designed for Air Conditioning Engineers, Design and Applications Engineers, Field Service Managers, Commissioning and Maintenance Engineers, Heating & Ventilating Engineers, Sales Managers and Sales Engineers, Architects, Plant Managers and Building Services Engineers. An excellent refresher to senior and more experienced staff.

A comprehensive Manual including a transcript of the lecture, formulae, exercises and graphic illustrations is provided including reference tables for ongoing use.
