India is ranked first in milk production, and its goal is to increase annual production to 300 million tons by 2024. The dairy industry requires multi-temperature cooling and simultaneous heating. In the present study, the ejector based transcritical CO₂ system with two evaporators (LT at -10°C...

Experimental evaluation of a multiejector CO₂ cooling system of 33 kW cooling capacity is conducted for an Indian supermarket at high ambient temperature context. The test-rig is designed to depict the actual supermarket cooling requirements in India with three different cooling temperature levels s...

The dry ice sublimation process of CO₂ is a unique technique in which temperature ranges below the triple point of −56 °C can be achieved in a CO₂ refrigeration system. However, during the evaporation process of the actual refrigeration system, the dry-ice blockage maybe happens in the evaporat...

There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been utilized due to higher investment cost and limited availability of systems fo...
