Image: Left: Regenerator diagram. Right: Proof of heating and cooling Current heat pumping technologies use a vapor compression cycle with a liquid refrigerant. In recent years there has been an increased interest in systems using a solid refrigerant instead, eliminating the negative environmental impact of today’s refrigerants. It is common...

The use of energy for space cooling is growing faster than any other end use in buildings, more than tripling over the past three decades. Global sales of air conditioners (ACs) have been growing steadily and significantly: since 1990, annual sales of ACs nearly quadrupled to 135 million units. There...

Fig.: Exploded diagram of an electrochemical compressor cell. To a layman, a heat pump seems to magically draw heat from thin air. But behind that perceived magic is a construction with mechanical compression of fluids, supplying the work needed for useful heating and cooling. This article presents an alternative...

Eight finalists are now selected for the Global Cooling Prize. Seven of the solutions are using technologies to remove humidity from the air, which makes cooling less energy intensive. The eighth solution uses phase transition in crystals to change temperature. The Global Cooling Prize is initiated by Rocky Mountain Institute....
