Cooling systems and heatpumps (5 cr)

Objective

You can study and analyse compressor cooling or heatpump systems with the help of the log p, h diagram.
You can identify the most common equipment and components related to cooling and heatpump systems and their function in the process. You are familiar with the most common refrigerants and their properties.
You can utilise free cooling and passive methods in cooling and in preventing overheating with solar shading.
You can dimension the most common direct and indirect cooling systems.
You can dimension the most common heatpump systems and connect them to heating systems.
You can calculate the energy consumption of cooling systems and heatpumps according to the D5 simplified methods of the National Building Code.
