<p>The refrigerating plant is used for milk transport between different collecting units. It comprises a boiler, with the role to release the ammonia vapours from a solution and to circulate it, a rectifier intended to retain the water vapours mixed with ammonia ones and to return them, by condensation, to the boiler, a condenser for the ammonia vapours, a capillary tube to convey the liquid ammonia, by heat exchange, to a vaporiser, an absorber with an expansion coil, a supply pipe for poor solution and another one for rich solution, a heat exchanger and a pipe for equalising the pressures between the absorber and the condenser.</p> |
