Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen's experiments. Adsorption is sometimes referred to as solid sorption. Adsorption refrigeration has been extensively researched in recent years because the technology is often noiseless, non-corrosive and environmentally friendly. The heat source for adsorption refrigeration can be fossil fuel, biomass fuel, nuclear fission, geothermal energy, waste heat, or solar thermal energy.

  • Eine Adsorptionskältemaschine bzw. adsorptionsgetriebene Kältemaschine (engl. adsorption driven chiller, ADC) dient der Kälteerzeugung und beruht auf der reversiblen Adsorption eines Aktivstoffes in eine Wirtstruktur. Der Funktionsablauf ist der gleiche wie bei einer Absorptionskältemaschine mit dem Unterschied, dass das sich der Aktivstoff (Kältemittel) nicht an eine Flüssigkeit, sondern an einen Feststoff anlagert. Der Aktivstoff (z. B. Wasser, Ammoniak, Methanol oder Ethanol) nimmt Energie aus der Umgebung auf und verdampft. Aufgrund der Verdunstungskälte kühlt die Umgebung dabei ab. Der nun gasförmige Aktivstoff wird von der porösen Wirtsstruktur aufgenommen und kondensiert in deren Poren. Aufgrund der Kondensationswärme erwärmt sich die Wirtsstruktur. Als Wirtsstruktur eignen sich alle Materialien mit der passenden Porengröße. Häufig eingesetzt werden Zeolithe, MOFs, Aktivkohlen oder Silikagele. (de)
  • Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen's experiments. Adsorption is sometimes referred to as solid sorption. It is very similar to absorption refrigeration (note that the second letter is different). The difference is that in adsorption refrigeration, the refrigerant or adsorbate vapour molecules adsorb onto the surface of a solid instead of dissolving into a liquid. In an adsorption system, an adsorber adsorbs the refrigerant vapour into a solid, while in an absorption system, an absorber absorbs the refrigerant vapour into a liquid. Adsorption refrigeration also includes a generation process where refrigerant vapour molecules desorb from the solid. In this process, there is no use of CFC's or ammonia the thermally driven cooling process is environment friendly. The characteristics of the adsorbate/refrigerant pair is crucial in determining the system performance of an adsorption refrigeration system. The typical system performance indicators for an adsorption refrigeration system are the coefficient of performance and the specific cooling effect.The refrigerants used in absorption systems are ammonia, water, or methanol, etc, which all experience phase changes between the vapor and liquid states - the same as in vapor compression refrigeration; while the adsorbent is a solid, such as silica gel, activated carbon, or zeolite. For example, an adsorption refrigeration device with active carbon fiber as the adsorbent and ammonia as the refrigerant was designed. Adsorption refrigeration has been extensively researched in recent years because the technology is often noiseless, non-corrosive and environmentally friendly. The heat source for adsorption refrigeration can be fossil fuel, biomass fuel, nuclear fission, geothermal energy, waste heat, or solar thermal energy. Adsorption refrigerators are available in the marketplace and are mainly used to produce chilled water from waste heat. Gas adsorption heat pumps are not currently available in the UK, but are just being introduced in Europe as small water or ground source packaged units that provide domestic, low-temperature space heating.

  • 吸附式制冷(Adsorption refrigeration),也称吸附式制冷系统或固體吸附制冷系统,是麥可·法拉第在1821年發明的制冷系统 。吸附式制冷類似吸收式制冷。其中的差異是吸附式制冷的吸附器(adsorber),會吸附制冷剂蒸氣到固體的表面,而吸收式制冷的吸收器(absorber)會將制冷剂蒸氣吸收,溶解在液體中。吸附式制冷中也會包括另一個過程,利用加熱的方式釋放固體中的制冷剂。 吸附式制冷的吸附質/制冷剂對(adsorbate/refrigerant pair)特性在其系統性能上相當的重要。典型的吸附式制冷的系統性能指標是性能係數(COP)以及其單位冷媒製冷能力(specific cooling power)。吸附式制冷常用的制冷剂有氨、水或甲醇等,在蒸氣態和液態之間相變,就像蒸氣壓縮製冷一樣,吸附質是固體,常用的有矽氧樹脂、活性炭、沸石。例如已有人設計用活性炭為吸附質,以氨為制冷剂的吸附式制冷。 吸附式制冷在近三十年有廣泛的研究,原因是吸附式制冷沒有噪音、無腐蝕性,也對環境友善。吸附式制冷的熱源有:化石燃料、生物燃料、废热、太陽熱能等。吸附式制冷系統已有產品,主要是用废热來產生冷水。氣體吸附的熱泵在英國還沒有產品,不過已經引進歐洲,可以提供低溫的室內供暖。 (zh)
