The consumption of energy in the world is increasing day by day, which results in faster depletion of energy resources. This problem to some extent can be tackled by using Waste Heat Recovery System. Waste Heat recovery process consists of using waste heat produced from a system for pre-heating or cooling the air in the same system or other. Large size capacity oxygen tanks are installed in hospitals for supplying oxygen gas. This liquid oxygen undergoes phase transitions while absorbing heat from surroundings thereby producing cold energy at the vicinity.From the study, we understood that around 3TR of cooling capacity is available which can be utilized for cooling purpose via insulated ducts. This will help in the conservation of energy. After simulation, we observe that there is an only small temperature difference between the inlet and outlets of the duct. Room simulation tells us that inside temperature of the room is around 292K when the surrounding temperature is 308K.
