Heat pumps or heat pumps, which transfer mechanisms are temperature by means of a thermodynamic cycle, being used mainly for heating.
A traditional heat pump, like all equipment, has a lifetime - between five and ten years, possibly a little more.
Now Norwegian researchers have developed a heat pump that they say can last virtually forever "- they calculate a life of 10,000 years.
Micropump eternal
The secret of "immortality" is in the miniaturization and the elimination of moving parts.
The new heat pump consists of numerous miniature heat pumps, each measuring no more than a cubic millimeter.
To heat a home you will need several thousand of them. But this is no problem because their structure allows them to be manufactured exactly like the thousands.
And more than that, the whole structure can be any shape, adjusting the application.
"The main advantages of the new heat pump is that you can adjust the size and shape, it is more durable than the heat pumps are today and is also more environmentally friendly," said Jan Bording and Vidar Hansen, University Stavanger.
Thermoelectric alloys
To eliminate moving parts, and Bording Hansen thermoelectric alloys used, eliminating compressors, pipes, and especially refrigeration gases, usually not very environmentally friendly.
In its place, electricity is converted directly to temperature differential, which can be used, for example, to heat homes.
"We do not want another large wood burning heater in the middle of the house, like old times. It will be much better to use smaller heat sources and clean," says Hansen.
He exemplifies the saying micropumps heat can be mounted on planes and placed under the floor - so the heat will flow from floor to ceiling, warming the whole house and more homogeneous.
"When the heat pump has a larger surface, it produces more heat," said the engineer.
And, apart from some accident that would destroy the material, the heat pump can be found by archaeologists of the future.
