ABSTRAKT

The importance of adsorption refrigeration and air conditioning technology is growing, as a response to the demand for more sustainable, low–carbon intensity technologies. These versatile systems work with heat from flat-plate solar collectors or waste heat at temperatures as low as 65°C. However, the market share of adsorption chillers is still a niche. Power density is one of the key factors to improve market penetration of such systems, allowing for smaller equipment at lower cost. Specific heat capacity is one of the determining factors of performance, affecting cycle dynamics and thermal performance, being related to the couple adsorbent-adsorbate. However, few experiments in the literature have considered real-size adsorptive beds and combined heat capacity of the adsorbed phase, as presented here. A scanning calorimetry technique is used to validate a representative mathematical model. The intensity of endothermal peaks is directly related to the ones related to the specific heat capacity of the adsorbed phase. The cp values for the range considered were lower than the cp values for the liquid phase but were closer to the liquid phase than to the vapor phase.
