Steam jet ejector cooling powered by waste or solar heat

A small scale steam jet ejector experimental setup was designed and manufactured. This ejector setup consists of an open loop configuration and the boiler operate in the temperature range of Tb=85–140°C. The typical evaporator liquid temperatures range from Te=5°C to 10°C while the typical water-cooled condenser pressure ranges from Pc=1.70kPa to 5.63kPa (Tc=15–35°C). The boiler is powered by two 4kW electric elements while a 3kW electric element simulates the cooling load in the evaporator. The electric elements are controlled by means of variacs.
