Methods of improving the performance parameters of the adsorption thermophysical battery (ATB) including, coefficient of performance (COP), specific cooling power (SCP) have been reviewed in this study. Adsorption thermophysical battery has received much attention in the last few decades due to its advantages in utilizing waste heat or solar energy and using environment-friendly refrigerants. This survey reviews 158 papers that propose method and technologies to improve ATB. Structures and operating conditions such as heat exchanger, solar collector, fins, heat and mass transfer, adsorbent-adsorbate working pairs are discussed in this review. It was collected from the review literature: (i) cooling capacity and COP are increased with hot water temperature increasing and with reduction of inlet cooling water temperature, (ii) the condensation temperature is inversely proportional with COP and SCP for single and double stages ATB, (iii) both SCP and COP are increased when the heat source is a relatively high temperature; (iv) operating cycle time is important to achieve the optimal system performance, where the COP increases with cycle time increasing for particular limits. (iv) novel adsorbent materials such as MOF can significantly improve the ATB performance, (v) enhancement in cooling capacity of the ATB can be achieved under high flow rates of hot and cold water, (vi) improving the adsorbent thermal conductivity can enhance the performance. This review can assist in selecting the ATB for future research works with improved COP and reduced cost when this system is driven by waste heat or solar energy.
