Integration of a magnetocaloric heat pump in a low-energy residential building
Research output: Research - peer-review › Journal article – Annual report year: 2018
The EnovHeat project aims at developing an innovative heat pump system
based on the magnetocaloric effect and active magnetic regenerator
technology to provide for the heating needs of a single family house in
Denmark. Unlike vapor-compression devices, magnetocaloric heat pumps use
the reversible magnetocaloric effect of a solid refrigerant to build a
cooling/heating cycle. It has the potential for high coefficient of
performance, more silent operation and efficient part-load control.
After presenting the operation principles of the magnetocaloric device
and the different models used in the current numerical study, this
article demonstrates for the first time the possibility to utilize this
novel heat pump in a building. This device can be integrated in a single
hydronic loop including a ground source heat exchanger and a radiant
under-floor heating system. At maximum capacity, this magnetocaloric
heat pump can deliver 2600 W of heating power with an appreciable
average seasonal system COP of 3.93. On variable part-load operation
with a simple fluid flow controller, it can heat up an entire house with
an average seasonal system COP of 1.84.
