Example text

The desorption activated energy is always much larger than the adsorption activated energy because it is the sum of the adsorption activated energy and the adsorption heat, and such a phenomenon will lead to a serious hysteresis phenomenon between adsorption and desorption [2]. For adsorption refrigeration most refrigerant molecules are polar molecular gases that can be absorbed under the van der Waals force, such as ammonia, methanol, and hydrocarbons that can be adsorbed by activated carbon, zeolite, and silica gel.

For example, Miles and Shelton, using small particle size of adsorbent, shortened the cycle time to 5 minutes [52]. 2 Compact Adsorption Bed This technology is particularly suitable for the occasion when the bulk sorbent is not applicable. Such technology had been used for metal hydrides for a long time [51]. The following study found that combining ENG with the adsorbent can enhance heat transfer performance, which was firstly proposed by Spinner and Le Carbone Lorraine and the thermal conductivity can reach 3000 W/m2 [40].

Demands for electricity increase as societies develop. 4% of the total electricity consumption. In China too, for example, in Shanghai City, in summer electricity consumption by air conditioning reached 45–56% according to data collected from 2010. If we analyze the energy utilized through the electricity generation process we find that energy efficiency for electrical generation is only about 40–50%, and there is a large amount of energy being released into the environment as waste heat at temperatures of around 70–200 ∘ C.
