Efficient ways of transferring energy in HVAC systems have been and still are a common need in industrial and private buildings. Extensive research has been done in this area. The development of new technologies opens up more ways to improvements. Among the most prospective of these, is the usage of nano technology, either in form of nano-structured surfaces or in form of nano-particles used in refrigerants. To estimate the efficiency of these approaches, simulations are used to accompany experiments in lab scale as well as in large scale up to industrial size. In the scope of the EnE-HVAC-project funded by the European Commission, the flow and conjugate heat transfer in a real size heat exchanger is investigated.
