MEFA solar-ice:
Ice storage and solar use in residential buildings

The solar absorber MEFA sun provides the heat pump with very high source energy temperatures and simultaneously regenerates the ice storage. The ice storage MEFA ice stores surplus solar energy for monovalent operation for the entire year. The ice storage MEFA ice can be used with minimum surface requirements, e.g. Garage entrances and water protection areas. In addition, the ice storage MEFA ice is available as a cooling source in the summer for passive building cooling. The MEFA powerbox always guarantees the use of the warmest energy source, ensures the constant regeneration of the ice storage tank and protects the heat pump against excessive source temperatures.

+ Very small space requirement for the ice storage.
+ As a rule, permit-free access also in water protection areas.
+ Due to the addition of solar energy high JAZ can be achieved.
+ The possibility of passive building cooling by the ice storage is given.
+ Cost savings due to low excavation costs.
+ High strength through polypropylene.
+ Solar absorber MEFA sun can be combined with PV as a PVT hybrid module.
