Abstract

The invention relates to a cylindrical air condenser (100) comprising a heat exchanger (110) which has a cylindrical or polygonal shape that develops in a vertical direction (Z) from a base or bottom to a top, and a suction device (120) provided with a motorized fan (121) housed in a frame (122) arranged on the top of said heat exchanger (110). The cylindrical condenser (100) further comprises a distributor element (130), housed inside the heat exchanger (110) coaxially therewith, said distributor element (130) comprising a plurality of conduits (131a, 131b, 131c, 131d, 131e) arranged coaxially one to the other, said conduits (131a, 131b, 131c, 131d, 131e) having a progressively increasing height from the top to the bottom of the heat exchanger (110) and a progressively decreasing transversal dimension, the configuration of the distributor element (130) being such that, starting from the top towards the bottom or base of the heat exchanger (110), a plurality of through openings (A1-A6) whose areas are nominally identical are defined therein in the vertical direction (Z).

Abstract

An economizer device for detecting the passage of a liquid is disclosed, comprising an electrically non-conductive main body and a passage channel for said liquid. The passage channel is also provided with a narrowing portion. The main body includes also a pair of holes made on opposite sides relative to said passage channel. The device comprises also a pair of conductive elements arranged on opposite sides relative to said narrowing portion, and each conductive element has a passage for the liquid. The device is positioned with a vertical central axis and perpendicular to ground, while the holes made on body are arranged at different height relative to the vertical axis; moreover two electrodes are inserted in said holes, so that the electrodes are fully buried in the device main body. Finally said conductive elements are provided with a conical portion converging to a cylindrical circular portion.
