    Steam Jet Water Vapor Refrigeration-2

    Steam Jet Water Vapor Refrigeration-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 […]

    Thermo-electric Refrigeration  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 […]

    * Magnetic Cooling

    MAGNETIC COOLING IT IS OBTAINED BY THE magnetisation followed by DEMAGNETISATION OF A PARAMAGNETIC SALT. It is based on the fact that there are some materials which raise their temperatures when adiabatically magnetised, and decrease their temperatures when adiabatically demagnetised. Each atom of the paramagnetic salt may be considered to be a tiny magnet. Initially […]
