Abstract:
The working pair is one of the main influencing parameter on performance of an adsorption heat pump (AHP). Researchers started to synthesize different adsorbents in order to improve the adsorption rate. Even the adsorption rate could seem very well, the new adsorbent could not be suitable for an AHP for given conditions. In this context, the effect of new adsorbent materials with isotherm Type V on adsorption-desorption processes of an unconsolidated adsorbent bed works for refrigeration are investigated. The adsorbate is taken as water. Type V isotherm equations for each adsorbent are predicted and the influence on the performance is analyzed. The constants in the equation that simulate the isotherm shape are found. The average temperature/concentration in the rectangular bed during the adsorption/desorption processes are plotted for different novel adsorbents; FAM-Z01, FAM-Z02, MIL101@GO5, and NH2-MIL-125(Ti). The performed numerical solutions for the case which is taken into account for this paper (evaporator temperature and bed heating temperature are 2 °C and 77.5 °C) showed that, MIL101(Cr)@GO5 has the best Specific Cooling Power for the volume of the bed which is 21.13 kJ/kga but has worst COP as 1.20. FAM-Z01 has 53.85 kJ/h evaporator capacity where this value is the best for the case.
