This paper provides a comparative study of the energy consumption and energy efficiency of a heating ventilation and air-conditioning (HVAC) system with three configurations. This system was used to cool an experimental room in an office building in more control scenarios realized by adopting different cooled water temperatures and chiller cooling systems. It is proposed an airпїЅwater mist cooled system for an air-cooled chiller. The three configurations of the HVAC system have the following configurations: (1) a...

This paper provides a comparative study of the energy consumption and energy efficiency of a HVAC system with three configurations. This system was used to cool an experimental room in an office building in more control scenarios realized by adopting different cooled water temperatures and chiller cooling systems. It is proposed an airпїЅwater mist cooled system for an air-cooled chiller. The three configurations of the HVAC system have the following configurations: (1) air handling unit (AHU) and fan-coil units (...

The paper analysis the influence of indoor temperature in case of a 2-roomпїЅs apartment built in the years 1975-1985, upon the thermal heating energy consumption. Thus, the thermal energy consumption is determined considering the thermal insulation measurements of the buildings elements taking in account a variation of the indoor temperature from 20?C until 24?C, according to the Romanian calculus methodology. The resulted values are compared with the experimental measurements realized for a 2 rooms apartment wit...
