Heating and Cooling SystemsLaajuus (10 cr)

Objective

The students can describe the centralized energy production and distribution system and the shares of different sources. They can explain the operating principles of combined heat and power production and heating plants. They are able to interpret and apply heating regulations and draw up the scheme of a district heating substation, boiler and solar heating system and dimension their main components.
The students can explain the operating principle of a district cooling system and ways of implementing them. They can calculate the process of compressor-driven refrigeration system, draw up and analyze the cycle in logp,h –diagram. They are able to interpret and apply cooling regulations and draw up the scheme of a refrigeration and heat pump system and dimension their main components.

Content
