Different Heat Pumps Integration into an Intelligent Building

In the current context with the prices for electrical and thermal energy increasing in addition to the international targets of lowering the CO

levels, it is mandatory to reduce the energy consumptions for the new and existing buildings, according to EU laws [1]. Especially in Romania, according to World Bank survey in 2019 [2], more than 42 % of the total annual energy consumptions are related to the buildings sector, which is even higher than the average in EU energy consumption for this field - of 40% [3]. Thus, for the new residential intelligent buildings, one of the key components to reduce energy consumption, is the integration of highly efficient heat and cold sources - such as heat pumps. There are a few constructive types of heat pumps that can be implemented, and the current paper is proposing a brief but concentrate analysis, in order to establish which type of the heat pumps presents the more advantages regarding the energy efficiency and flexibility.
