A building heating system had high energy consumption and did not meet the requirements of environmental protection, so it was needed to be reformed. After recalculating heat load, found that source, pipe network specification, radiator area original were oversized. comparing with a gas-fired boiler, source transformed into water pump system. The supply temperature lower than boiler. Generally,...

Abstract Photovoltaic-thermal (PV/T) systems and hydronic radiant floor heating can enhance energy efficiency economic viability. This study investigates their integration through experimental research designs an experiment to test performance under typical winter conditions. The heat pump system achieves average COP of 5.66 photovoltaic power output 107.5 W. underfloor quickly reaches maintain...

The paper presents the learnings from designing and running a model predictive control (MPC) of heating system in school building. Several real-life applications MPC controlled have been presented literature. Most them work by controlling room temperature usingn thus need reference measured Some single-zone as reference, while others use some kind mean multiple rooms. In present experiment, use...

Through the hydraulic balancing of heating systems, significant energy savings in residential buildings can be achieved. These savings refer to (primary) heating energy, as well as to (secondary) electric energy for the supporting building services. This paper addresses the use of KNXtechnology and networks (Smart Buildings) in multi-storey residential buildings to ensure a dynamic adaption of ...
