Study Guide

Objective

You can study and analyse a compressor cooling or a heat pump system with the help of log p, h -diagram. You can recognise equipment and main components and their function in the process. You are familiar with the most common refrigerants and their properties. You can calculate the cooling energy demand of a room or a space in a building and the overheating period in hours per year with a dynamic simulation program. You can utilise free cooling and passiv methods in cooling and in prevention of overheating with solar shading. You can dimension the most common direct and indirect cooling systems. You can dimension the most common heat pump systems and connect them to heating systems. You can calculate the energy consumption of cooling systems and heat pumps according to D5 simplified methods.
