“…Mogaji 15 made performance calculations for an advanced solar VAR system using NH 3 ‐H 2 O solution as the working fluid. Pop et al 16 presented a new analytical model that can reveal the thermal behavior of all components of the solar ammonia‐water absorption system serving different types of food storage, powered by parabolic corrugated collectors. They calculated the hourly variation of NH 3 H 2 O solar absorption system performance.…”

Autoclave devices are used to perform high‐temperature sterilization processes under pressure. Autoclaves can be integrated with an absorption refrigeration cycle to utilize the waste heat generated at high temperature during the process. Today, many studies are carried out on the evaluation of energy resources. In this study, it is designed to obtain a cooling load by adding an integrated sub‐cycle to the waste steam heat of the autoclave device in a sterilization unit. In the lower cycle, the ammonia/water absorption refrigeration cycle is used. According to the energy analysis; With the condition that the cooling temperature is 7°C, the generator temperature of 95°C and a cooling load of 130.9 W occurred with 531.7 W of waste heat received by the absorption cooling system. Accordingly, an efficiency of COP 0.246 was obtained. The energy analysis of the absorption refrigeration cycle can improve the energy efficiency of the autoclave and save energy. In addition, the obtained cooling load will be preserved in medical supplies that need to be kept cold.
