“…In adsorption heat pumps, the adsorption and desorption processes have to be reversible to provide repetition of the same cycle. Therefore, the interaction between adsorbent and adsorbate must be a physical adsorption type [4,23]. Table 3 illustrates the comparison of adsorbent-adsorbate pairs according to maximum adsorbate capacity, heat of adsorption values, adsorbent specific heat, energy density, and operating temperature range [12].…”

“…According to the new regulations, the conventional vapor compression systems are currently worked by using hydrofluorocarbons as refrigerant. However, the use of these new refrigerants has also been restricted due to limitation of the emission of some greenhouse gases (CO 2 , CH 4 , N 2 O, hydrofluorocarbons, PFC, and SF 6 ) in Kyoto protocol. The greenhouse gases might be banned in the next decades [3,4].…”

“…A new generation of solid sorption heat pumps and coolers [5][6][7] have a good compromise between chemical heat pumps [8][9][10] and adsorption heat pumps [11][12][13][14][15][16][17]. The sorbent bed of these heat pumps consists of adsorptive materials (for example, active carbon fibre) and micro/nano crystals (metal chlorides, metal hydrides etc.)…”

In the 21st century the way to increase the efficiency of new sources of energy is directly related with extended exploration of renewable energy. This modern tendency ensures the fuel economy needs to be realized with nature protection. The increasing of new power sources efficiency (cogeneration, trigeneration systems, fuel cells, photovoltaic systems) can be performed by application of solid sorption heat pumps, regrigerators, heat and cold accumulators, heat transformers, natural gas and hydrogen storage systems and efficient heat exchangers.

Industrial chemical heat pumps (ICHPs) provide an ability to capture low -grade heat rejected from industrial sources and to reuse the heat increased temperature in industrial processes. Also it can be used for residential heating, cooling, water heating and energy storage. Several temperature boost levels can be obtained according to chemical reaction couple chosen. It can be either single source system or dual source system connected with available reject heat source. Dual source system is more effective than single source system and higher output temperature levels can be obtained. Reject heat source temperature and desired temperature boost are important in chemical reaction couple selection. Chemical reaction couple must be chosen carefully to provide the highest efficiency in all candidate systems. Economical feasibility of industrial chemical heat pump can be determined after calculations according to heat pump capacity. In this study, economical analysis of an industrial chemical heat pump system was accomplished compared with a steam boiler. Economical calculations was carried out and curves that show the relations between investment cost and capacity of chemical heat pump, investment cost and capacity of steam boiler, reject heat capacity and net savings were obtained for waste heat capacities below 2000 kW. It is determined that the chemical system is feasible if the waste heat capacity is higher than a certain value according to economical parameters and lifetime. Also, net gain increases almost linearly with increasing waste heat capacity.
