Energy Efficiency - Cooling and Heat Pump Technology in One System

About the course

In periods of cheap electricity, the drive and ambition for energy efficiency is low. Low-hanging fruit such as adjusting individual components may be implemented, but system aspects, which may seem to be more complex, are often forgotten.

This course, conducted by Martin Larsson and Ola Gustafsson, presents how different cooling and heating systems work and addresses system aspects with high energy efficiency potential. The importance of temperatures, stable and demand-adapted operation, etc. is reviewed based on practical examples.

Examples of cooling systems are shown and we go through how they work. Schematic pictures and principle diagrams will be the starting point for discussions and supervised group work where we solve "problems". This group work leads to an understanding of the principles and insight into how different measures affect the cooling system and how it is that certain measures have such great energy saving potential.

Different types of buildings have different conditions regarding power peaks and how the cooling is distributed. We look at the similarities and differences between different buildings, such as offices, hospitals and grocery stores, which may require different temperatures or operate all year round.

We review the differences and similarities between process cooling and comfort cooling, and provide examples of cooling systems for different types of businesses.

Heat recovery from chillers is very similar to heat pumps and is covered in the course. Principles are discussed on what is required to make it work, such as operating ranges and other limitations.

Learning objectives

The aim is that after the course participants

• understand the need to look not at individual components but at a whole system to achieve full energy efficiency potential. 
• can appreciate how, for example, the temperature in one part of the system can affect other parts 
• realise that different systems have different potential and understand that different businesses have different conditions
  
   

Target group

This course is aimed at people who come into contact with different cooling and heating systems, such as

• Property owners
• Property managers
• Purchasers
• Technical managers at municipalities/county councils
• Consultants
• Technology companies

Language

The course is held in Swedish and the course material is in Swedish.
