  • Refrigeration-Steam Jet -2

    Refrigeration-Steam Jet -2

    Refrigeration-Steam Jet -2 Steam refrigeration means refrigeration from heat. It uses a steam nozzle to create vacuum in the flash chamber. High vacuum causes water to evaporate and evacuate  and get mixed with high velocity steam jet. These are are compressed in the diffuser. Consequently these are condensed in condenser for recycling. It is able to create […]

    Refrigeration-Thermo-electric

    Refrigeration-Thermo-electric Thermo-electric refrigeration uses semi-conductors. A semiconductor is a combination of two materials having high electrical conductivity and low thermal conductivity. The property defining the quality of thermo-couple is ‘Figure of Merit’. Figure of Merit = Z= α2σ/k Where α is the Seebeck coefficient of the two materials of the semiconductor σ is the electrical conductivity k is the […]

    * Magnetic Cooling

    MAGNETIC COOLING It is obtained by the magnetization followed by de-magnetization of a para-magnetic salt. It is based on the fact that there are some materials which raise their temperatures when adiabatically magnetized, and decrease their temperatures when adiabatically demagnetized. Each atom of the para-magnetic salt may be considered to be a tiny magnet. Initially the […]
