In the present study, the performance of a 33 kW multiejector trans-critical CO₂ cooling system is experimentally evaluated for a supermarket application with/without internal heat exchanger and evaporative cooling. In order to enhance the overall performance of the system for tropical regions, the...

CO₂ cascade heat pump system has been developed to realize an ultra‐low temperature below the triple point of 0.518 MPa and − 56.6°C or less by flowing dry ice solid‐gas state of CO₂ in a refrigeration system. Solid CO₂ in the refrigeration system may cause to block the flow in the evaporation...

Low-carbon hydrogen is considered as one of the key measures to decarbonise continental Europe and Japan. Northern Norway has abundant renewable energy and natural gas resources which can be converted to low-carbon hydrogen. However, Norway is located relatively far away from these markets and...

Low temperature Rankine cycle is a prominent solution for power generation in Waste Heat Recovery (WHR) application. The performance of this cycle is affected by various parameters including characteristics of the heat source, working fluid and constraints in the system. In cases where the heat...
