The study set out to compare a conventional system using the city’s district heat supply with one using an “outdoor air-water” heat pump. One part of the analysis is the energy performance of the renewable energy source. The study is also addressed the benefits of saving on conventional heat source and the period of financial return on the heat pump investment.

https://doi.org/10.4467/2353737XCT.14.241.3329The target of this contribution is to know if we can use displacement ventilation for the so-called free cooling of a room. What flow rate of air do we need in order to sufficiently reduce the thermal loads in the classroom? We search for the answer to this question by using CFD tools. We only use air from the exterior without any cooling system.
