Low-Temperature Heating Systems Control in Low-Energy Buildings

Abstract

The paper deals with the control of low-temperature heating systems and their responses to changes in indoor environment with the main focus on indoor environmental quality and real energy savings reflecting low-energy buildings energy needs.
In relation to energy savings, utilization of low-temperature heating systems is increasing today, in connection with low-temperature heat sources, such as heat pumps. Lower temperature difference between the heating unit and the environment, along with the heat capacity, however, requires better control to be able to make effective response to potential changes in the indoor environment.
