Haier, a global leader in consumer electronics and appliances has launched a new compressor-free thin-film solid-state refrigeration technology. Haier created this new technology through integrating Silicon Valley resources, Haier Group R&D,GEA, Haier America R&D, Liquid King, Xi'an Jiaotong University, South China University of Technology and other resources. The new technology breaks the technological bottlenecks of compressor-based refrigeration appliance that have been used in the industry for a century.

So what is thin-film solid-state refrigeration?
It is one kind of compressor-free refrigeration technology that adopts innovative materials and novel technique to make thin-film solid-state refrigeration modules, generating a cooling effect when direct power is applied.

Compared with compressor-based refrigeration, it has four major advantages:

No Vibration
To maintain its quality, wine requires particular storage conditions, as any vibrations will disorder its molecular structure. When in standard mode, with thin-film solid-state cooling, a set of high efficiency heat exchange systems without moving parts is adopted to create a completely still wine storage environment.

Precise Temperature Control
Constant temperature and humidity are indispensable factors for the ideal wine storage. Temperature variations will affect the wine's taste and lifespan, and humidity variations may cause the wine to oxidize or change odor. Haier's thin-film solid state wine cellar adopts dual power control electronics to ensure temperature fluctuation less than 0.1K and constant humidity.

Low Noise
Contemporary cooling and refrigeration products use a compressor, with a typical noise level of 38–42 dB. The thin-film solid-state refrigeration technology removes the compressor, which means it creates no noise when in standard mode.

Haier's thin-film solid state wine cellar uses H2O/CO2 as a medium with a Global Warming Potential (GWP) of just 1, as compared to >1700 for compressor-based systems. Furthermore, the heat exchange capacity is 8X higher than ordinary systems, reducing energy consumption to meet the California Energy Standard.

How will this disruptive refrigeration technology be applied?
The solid-state refrigeration technology will be firstly applied on a new wine cellar.

Although compressor-based wine coolers have good cooling ability and a large temperature range, the periodic noise of generally 38-42dB is not easy to avoid, and the rotation of the compressor causes the wine cooler to vibrate constantly, thus disturbing the molecular structure of the wine, which will affect the taste of the wine; meanwhile, the periodic on and off of the work of the compressor will cause the temperature fluctuations of ± 2 K, and the temperature fluctuation will speed up the oxidation of the wine.

The solid-state wine cellar can avoid the above problems. To maintain its quality, wine requires precise storage conditions with optimal environment needs to preserve taste that can be affected by subtle vibrations or temperature changes. This advanced compressor-free cooling technology creates the ideal storage conditions for the wine. The application of the solid-state refrigeration technology will refresh the compressor-based refrigeration and demonstrate Haier’s leadership in the new space.
