A type of new molecular sieve solution thanks to new technology to dehydrate dryer

Thankfully, this hurdle was overcome by a new technology that entered the market just recently, in 2013: a refrigeration dryer with molecular sieve equipped with a totally different type of thermal mass – a phase changing material (PCM). Phase changing materials can store and release vast quantities of energy if they are harnessed at the precise point at which they undergo a phase change, such as between liquid and solid states. These materials work according to the same principle by which ice cubes keep a drink cool for an extended period in the summer. The temperature of the drink remains constant as long as the ice cubes remain melting in the glass. They are capable of absorbing a significant amount of heat before melting completely; consider that the same amount of energy is required to change solid ice with a temperature of 0 °C to a liquid as is needed to heat water from 0 °C to 80 °C.

These thermal masses are also known as latent heat thermal masses owing to their capacity to store thermal energy virtually invisibly for long periods with only minor losses and their ability to accommodate any desired repetition cycle. Some familiar applications of this technology include the heat pillows used by some athletes in winter, as well as cool packs that allow refrigerators to continue to provide cooling during periods of power failure, and paraffin-filled storage elements in the tanks of solar-thermal systems.
