The principle ...

Refrigeration principle takes the name of two scientists, James Prescott Joule and William Thompson. This procedure is called a Joule-Thomson trial.

Il processo in cui il liquido o gas cambiare la sua temperatura quando viene Forzato attraverso una valvola di espansione o tubo capillare in un sistema isolato dove Nessun trasferimento di calore ambientale.   A STP (temperature and pressure), all gas conforms to the Joule-Thomson process with elixir, neon   and   hydrogen gas.

Refrigeration . Applies to any system of small appliances available for purchase at the largest walk-in condominium that has a state of the art facility. Gas freon or the refrigerant fluid absorb the heat internally from the refueling zone or cell heat exchanger evaporator  and transfer heat to the external refrigerant capacitor   .

The basic principle is that Refrigeration with the use of a calorie pump, the refrigerant comes compressed to the capacitor and tubular capillary which increases its temperature (50-60 ° C) and pressure (750 kPa) in refrigerated refrigerated unit unit of condensation at 32 ° C depending on the existing ambient temperature. Entering the vaporizer gases steam and vaporizes for improvised expansion in the evaporator tube and lowers the pressure to atmospheric pressure (120 kPa) and the temperature of 32 ° C to -24 ° C. a heat pump by means of a calorie pump to the capacitor must transform the vapor into the liquid state at a higher temperature and complete pressure during the calorie transfer cycle.

Theoretically, after the cycle the quantity of refrigerant rimane uguale


  2. Aspiration tube: low pressure lathe with non-return value.
  3. Use liquidated version of condensation unit with value of non-return.
  4. Water heater, which will gradually be added.
  5. Refrigerator recovery point.
  6. Solid condensation unit has the shape of tubers in serpentine, with electric barbed wire for efficient ambient heat transfer.
  7. Point of application of the vehicle to remove the impurity and the first fatigue of the refrigerant carcass.
  8. Tube capillary as an orifice in which the diameter of the internal and lung is calculated to supply the flow of liquid. An alternative to capillary is the value of expansion for the refrigeration and large group frigoriferi in particular.
  9. Evaporator or unit of coil, of solid tube and serpentine on the lamination or fusion tube of aluminum alloy, evaporator and piastra. Serpentine on its evaporator is also widely used in refrigerators and condensers. Tubo is an aluminum frame. The frame has a coefficient of heat transfer coefficient, but is more expensive and costs more than aluminum, which is lighter. Evaporator tube of aluminum on its lamellae is better at absorbing heat as frame, simply increasing the thickness of the aluminum strip.
  10. Accumulator, solute in frame or aluminum.
