High-Efficiency Solid-State Cooling Systems for Residential Buildings

energyPrototypeTRL 3

Imagine a cooler that doesn't use any harmful gases or liquids, but instead uses special metals that change temperature when stretched. It works like a sponge for heat, squeezing it out of the air using mechanical force. This means no more leaking refrigerants and a much smaller electricity bill.

Who can put this to work

HVAC Manufacturing
enterprise
Target: Air conditioning unit producer

If you are an AC manufacturer dealing with strict environmental regulations on refrigerant gases — this project developed a solid-state cooling system that uses metals instead of fluids. This allows you to offer products with zero global warming potential and a potential efficiency increase by a factor of two to three.

Green Construction
mid-size
Target: Sustainable building developer

If you are a developer dealing with high energy costs in residential projects — this project developed an elastocaloric cooling device that targets a 2 to 3 times efficiency increase over current HVAC systems. This significantly cuts down global energy consumption in the residential building sector.

Industrial Components
SME
Target: Electric drive and motor manufacturer

If you are a component supplier dealing with the need for specialized actuators for new cooling tech — this project developed an efficient electric drive unit specifically suited for elastocaloric system devices. This creates a new market for high-precision drive units in the cooling sector.

Frequently asked

Quick answers

What is the expected cost or price of the system?

Based on available project data, specific cost or pricing information is not provided; the focus is on energy efficiency and material replacement.

Can this technology be scaled to an industrial level?

The project aims to develop a functional device for residential buildings and a validation environment for future devices, suggesting a path toward industrial scaling.

Who owns the IP or how is licensing handled?

Based on available project data, the consortium includes one high-tech company from Ireland and three universities, but specific licensing terms are not listed.

How does it integrate with existing building infrastructure?

The project targets the residential building sector, aiming to replace or improve upon state-of-the-art HVAC systems through a new device architecture.

What is the timeline for market availability?

The project period runs from 2024-10-01 to 2027-09-30, indicating the development phase concludes in late 2027.

Consortium

Who built it

The consortium is research-heavy with a 75% university presence (3 out of 4 partners), indicating a strong focus on fundamental material science and simulation. However, the inclusion of one high-tech SME from Ireland provides a critical bridge to commercialization and industrial application of the electric drive units.
