Title: Indoor Air-Conditioning Unit With Effective Dewdrop Collection
Inventor: CHEONG JEE HOW
IPC: F24F13/22
Filed: 2016-03-29
Abstract: An indoor air-conditioning unit (100) includes a chassis body including a front heat exchanger (110) and a rear heat exchanger (112) for cooling the air. The front heat exchanger (110) and the rear heat exchanger (112) having a number of tubes (141a, 141b) carrying a refrigerant and a number of heat exchanger fins attached to the number of tubes (141a, 141b) housed in an enclosure. A cutting edge (122) of the front heat exchanger (110) formed by a number of heat exchanger fins is above the tube (141a) of the front heat exchanger (110). The dewdrops from the cutting edge (122) of the heat exchanger fins flows to the tubes (141a) of the front heat exchanger (110) and to the heat exchanger fins angled to guides the dewdrops into a bottom portion. The cutting edge (124) of the rear heat exchanger (112) is such that it forms a round shape around the copper tubes so as to prevent sharp fin tip, which may trigger off water drips vertically down out of the drain pan area. The dewdrops from the cutting edge (124) of the heat exchanger fins flows to the tubes (141b) of the rear heat exchanger (112) and to the heat exchanger fins angled to guide the dewdrops into a bottom portion. The chassis body includes a drain pan (114) positioned below the front heat exchanger (110) and the rear heat exchanger (112) for collecting the dewdrops.  Most illustrative diagram: Figure 1

Abstract: In order to regenerate a multilayer filter bed (11) which has been used for separating flocculated matter from liquid, the following steps are carried out. Firstly,the vessel (10) containing the filter (11) is filled with rinsing water supplied via a supply line (22) and nozzles (19a). Secondly, compressed air is supplied to the filter (11) via supply lines (23, 24, 25) and respective nozzles (19a, 20a, 21a) to break up the filter cake deposited on the filter (11) and to form a turbulent slurry above the filter (11). Thirdly, the supply of compressed air is discontinued, and filter particles in the slurry are allowed to settle. Fourthly, compressed air is forced into the vessel (10) via a supply line (18) so as to force the slurry out of the vessel (10) via a dip pipe (14).
