Course detail

Refrigeration and Heat Pumps

FSI-LC0Acad. year: 2017/2018

The course deals with the design and construction of refrigeration devices and heat pumps. Students are gradually introduced to the issue of determining the required cooling capacity, choice of suitable refrigerant, individual components selection and overall design of the equipment. Students are familiarized with the current legislation and requirements for installation and commissioning of the proposed facility.
