Heat Recovery with Commercial, Institutional, and Industrial Heat Pumps

Dr. Vasile Minea worked as a professor at the Bucharest Technical Construction University for over 15 years, teaching courses such as HVAC systems for civil, agricultural, and industrial buildings, as well as thermodynamics, heat transfer, and refrigeration. During this period, his R&D works focused on new technologies for heat exchangers, residential and industrial heat pumps, development and experimentation of advanced compression-absorption/resorption heat pumps concepts, as well as on the usage of solar energy for comfort cooling processes and industrial cold water and ice production. Since 1987, Dr. Minea has been working as a scientist researcher at the Hydro-Quebec Research Institute, Laboratory of Energy Technologies in Quebec, Canada. His research activity mainly focused on industrial refrigeration, heat recovery technologies in large-scale commercial/institutional heating, ventilating and air conditioning systems, and various industrial processes (as drying), low-temperature geothermal heat pumps, and low-enthalpy power generation cycles.
