Numerical analysis of a magnetocaloric heat pump implementation into a residential building

Research output: Contribution to conference without publisher/journalPosterResearchpeer-review

Abstract

The EnovHeat project aims to develop a high-efficiency heat pump for dwellings based on the active magneto-caloric regenerator (AMR) technology. Such device operates according to principals which are different from conventional vapor-compression cycle heat pumps. It therefore allows implementation of the magneto-caloric heat pump in a single hydronic loop coupling directly the heat source and the heat sink without additional heat exchangers. Moreover, several parameters can be controlled in order to perform efficient part load power generation.
The objective of this work is to understand how to integrate a magneto-caloric heat pump into a residential building and establish a control strategy for such device. A numerical model of a single family house with water based under-floor heating and horizontal ground source heat exchanger is created. It is used to demonstrate the feasibility and the advantages of the AMR implementation in a single hydronic loop system. Investigations are then carried out on the impact of such configuration on the overall building design, performance and control. This work provides new requirements and constraints for the design of domestic AMR. Finally, the performance of the integrated magneto-caloric heat pump system is compared with conventional heat pumps one.
