Although the basic installation arrangement and sequence within Technical Building Equipment, based on generation, distribution and transfer of energy quantities, has remained virtually unchanged for some time, this essentially grid-connected world of installations could soon change significantly for different reasons. This feasibility study presents an almost disruptive approach, based on mobile multifunctional, chargeable and unchargeable PCM-TGA robot technology, which should be able to perform room conditioning (esp. heating, room air quality) as well as room monitoring in at least two rooms via a mobile module. Charging takes place at a plug and play transfer station, e.g. via a decentralized heat pump system integrated in the brickwork. First, the authors show the transdisciplinary reasons, which are essentially socio-politically evidence-based, for the need for additive technological development. Then, both the overall system that consists of a decentralized plug-and-play heat pump transfer station integrated in the brickwork and a mobile robotized heat distribution system, which is not tied to a pipe system, are explained. Based on an exemplary floor plan, living areas will then be shown that require permanent conditioning as well as those that can have discontinuous conditioning via the robot. Feasibility is demonstrated by means of building simulation of the load profiles, leading to appropriate storage dimensioning using a suitable phase change material. Here the authors refer to their extensive theoretical and experimental knowledge in handling dynamic PCMs when creating a prototype. Finally, the technological approach undergoes a critical assessment.
