<p>The invention is a new cooler with condensation operating at different pressures, wherein the refrigerant fluid, in the liquid state, is taken from the bottom of a tank (B), conveyed at a suitable pressure into an expansion valve (I) in order to successively flow through a coil or evaporator (P1) and expand immediately, thus decreasing its pressure and temperature. The evaporated fluid, which has accumulated the heat taken from the environment through the evaporator (P1), is conveyed to a suction pump/compressor (E) that in turn conveys it again to the tank (B, C) through a pressure reducing valve (H) that allows the fluid in the liquid state to flow therethrough only after the set pressure has been exceeded.</p> |
