Abstract

The invention allows to increase the thermodynamic efficiency of condensation of moisture from ventilating air. Plates 2 are located above the exhaust shaft 1. The rod 3, made of heat-conducting material, is installed along the shaft axis, has a heat insulating coating 5 and is equipped with fins 4 at the end opposite to the plates 2. In the evacuated internal cavity (CW) 6 the rod the central tube 7 is located. The upper end of the tube is mounted in the region of the ribs 4, and the lower end covers the annular partition 8, which is in contact with the inner surface of the rod. VP 6 above the partition is partially filled with coolant (TH) 9, and the rest of VP 6 and pipe 7 with non-condensing gas 10. Changing the atmospheric air thickness, the pressure in the upper part of the rod changes, which causes the displacement of the V-section vapor non-condensable gas until the vapor pressure Tli reaches its original value. Moving the interface causes a change in the surface on which heat is removed to the environment, resulting in a heat flux removed from the fins 4 and their temperature remains unchanged.

Description

The invention relates to ventilation devices and is an improvement of the invention according to the author. St. No. 798462.

The purpose of the invention is to increase the thermodynamic efficiency of condensation of moisture from ventilation air.

The drawing shows a device for condensing moisture from ventilating air, a cross-section.

A device for condensing moisture from ventilation air comprises

The plates 2 located above the exhaust shaft I, the rod 3, is of thermally conductive material, located along the axis of the shaft 1, provided with ribs 4 on the opposite end of the plates 2 and having a thermal insulation coating 5 of the core. The rod 3 is made of an evacuated internal cavity 6 and is there is a central tube 7, the upper end of which is located in the zone of the plates 2, and an annular partition 8, which covers the lower end of the tube 7 and the coil plate

with the inner surface of the rod 3, the cavity 6 of the rod 3 above the partition 8 is partially filled with coolant 9, and the rest of the cavity 6 and the pipe 7 with non-condensable gas 10.

A device for condensing moisture from the ventilation air works as follows.

The ventilated air, the passage through the shaft 1, washes the fins 4. The water vapor contained in the ventilating air condenses on them. The heat accumulated during the condensation of moisture is perceived by the coolant 9 contained in the rod 3. As a result, the coolant 9 evaporates and moves to the upper part of the rod, pushing the non-condensing gas upwards 10. In this part of the rod, the vapor of the heat-transfer agent 9 condenses with the release of heat, which dissipates through the plates 2 into the environment. The condensed coolant 9 returns to the lower part of the rod 3 under the influence of a gravity rod. When the temperature of atmospheric air decreases, the pressure in the upper part of the rod decreases, causing the vapor boundary 9 of the coolant 9 to move with the non-condensing gas 10 down until the vapor pressure the heat carrier 9 ne will reach the initial value. This reduces the surface on which it occurs.

heat removal to the environment. Thus, the heat flux removed from the fins 4, and hence their temperature, will remain unchanged. When the temperature of the atmospheric air rises, the pressure in the upper part of the rod 3 increases, which causes the indicated interface to be displaced upward until the vapor pressure of the coolant 9 becomes equal to the initial value. This increases the surface on which the heat is removed. Thus, the heat flux and, therefore, the temperature of the fins 4 remain unchanged. Invention Formula Device for condensation of moisture from the ventilation air according to ed. St. No. 798462, characterized in that, in order to follow the thermodynamic efficiency of moisture condensation from ventilating air, the rod is made with an evacuated internal cavity and is provided with a central tube located in it, the upper end of which is located in the rib zone, and an annular partition, covering the lower end of the pipe and contacting the inner surface of the rod, the rod cavity above the partition wall partially filled with coolant, and the rest of the cavity and the pipe with non-condensing gas. 2 b Editor Y.
