Two-zone air-conditioning unit with heat recuperation

Abstract: Disclosed is a two-zone air-conditioning unit with heat recuperation consisting of a housing (1), two paddle wheel fans (2, 3), a recuperative countercurrent heat exchanger (4), an air heater (5) and a filter (6). The invented air-conditioning unit is characterized by location of a single rotary mixing flap (8) within the housing (1) between the inlet circulating air (V1) branch (9) and outlet section of the recuperative countercurrent heat exchanger (4) and the main filter (6), whereby the flap (8) cover in its extreme positions and inside the housing (1) both said inlet circulating air (V1) branch (9) and said recuperative countercurrent heat exchanger (4) outlet section.

Control of flooding in a countercurrent flow reactor by use of temperature of liquid product stream

Abstract: A process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The temperature of at least a portion of the liquid stream in the reactor is used to control the flooding characteristics of the reactor.

Cooling tower with single side air feeding

Abstract: The utility model discloses a cooling tower with single side air feeding. The cooling tower comprises a square tower body, wherein an air cylinder is arranged on the top of the tower body; a fan is mounted on the air cylinder; an air inlet is formed in one side of the tower body; a transverse flow heat exchange area close to the air inlet and a countercurrent heat exchange area far away from the air inlet are formed inside the tower body; the transverse flow heat exchange area is internally provided with a first packing material which is adhered to the inner wall of the tower body; a second packing material is arranged on the top of the countercurrent heat exchange area; spraying mechanisms in match are respectively arranged above the first packing material and the second packing material; the air cylinder is positioned right above the countercurrent heat exchange area. By arranging the transverse flow heat exchange area and the countercurrent heat exchange area, cold air entering the tower body can be sufficiently utilized, the cooling effect is good, and the problem that he cooling effect is poor in single side air feeding is solved; due to adoption of a shutter plate, dust can be prevented and large articles are prevented from falling into the cooling tower; due to an adopted adjusting valve, water flow in a corresponding water distribution tube can be controlled, the water flow can be adjusted, and the cooling efficiency of the cooling tower is maximized.
