摘要:
A through-wall sleeve assembly (10) includes an elongate sleeve (15) having an axial passage, open ends and a radially constrictable frustoconical flange (16) at one of the ends. The sleeve (15) is inserted through a bore in a wall, with the flange (16) at the leading end of the sleeve (15) so that the flange (16) is constricted by the wall or by an outer tube inserted in the bore. The flange (16) returns to an expanded, relaxed condition when it projects beyond a remote surface of the wall and forms a seal (20) with the remote surface when the sleeve (15) is drawn back. An item such as a nozzle (36) hook or eye having external threads (34) is inserted in the axial passage and fixed relative to the sleeve (15).
摘要:
An indoor unit for air conditioners of the invention has a front panel (4) having a suction grille (41) at least at a central portion (4a). Indoor air is sucked in through gaps (42) of the suction grille of the front panel (4), and cooled air is blown out into a room (99) through an air outlet (8) located below the front panel (4). A lower portion (4b) of the front panel (4) opposed to a lower portion (3b) of the front grille in proximity to an upper portion of the air outlet (8) is shaped to have dips and bumps. As a result, dew condensations on the front face side of the front panel lower portion can be prevented without causing any cost increase.

A heat exchanger (1) in which a first casing (19a) is disposed within a second casing (5) and delimits, within the interior of the second casing (5) itself, two lateral chambers (23, 24) able to communicate with the interior of a cabinet (3) to be air-conditioned; the first casing (19a) has two side walls (20, 21), a water collection vessel (25) connected to the side walls (20, 21) in a fluid tight sealing manner, and a cover (32) releasably coupled to the side walls (20, 21) and to the vessel (25) in a sealed manner; the first casing (19a) housing a heat exchanger unit (35) being disposed in a position raised with respect to the vessel (25), a dividing partition (41) extending between the heat exchanger unit (35) and a bottom wall (26) of the vessel (25) to define an inlet chamber (42) and an outlet chamber (44) each communicating with an associated lateral chamber (23, 24) and each housing an associated single flow deflector screen (46, 47) fixedly connected to the cover (32).
摘要:
An automatic draining apparatus comprises a float (35) which is floating on the liquid surface in a receiving tank (25) receiving liquid from a liquid source (7), a suction nozzle (28) having a liquid inlet port (29) located in liquid in said receiving tank (25) and connected to a vacuum tank (3) evacuated so as to keep the inside thereof at a specified degree of vacuum, a liquid inlet port open-to-close valve (34) being attracted toward said liquid inlet port (29) according to downward movement of said float (35) by a lowering of the liquid level in said receiving tank (25), and guide means (37, 47, 51 and 57) which regulate the path of movement of said liquid inlet port open-to-close valve (34) so that said liquid inlet port (29) is opened or closed according to upward and downward movement of said float 35. In an alternative apparatus, liquid is evacuated from a tank (63) under the pressure of air being introduced into the tank (63) from an air supply source (70), and electrical or electromagnetic valves (65, 66, 72, 74, 91) controlling the communication of the tank (63) with a liquid source (7), air supply source (70), drain outlet passage (67) and vent (73) are controlled according to the level of liquid in the tank detected by level detecting means (66).
摘要:
An air conditioner includes a pump (7) for periodically removing condensate (2) from a sump (1), the operation of the pump (7) being responsive to the condensate level in the sump (1) as sensed by a positive temperature coefficient resistor (8) located in the sump (1). The use of a positive temperature coefficient resistor has the advantage that foreign matter such as metal particles or biological growths do not impair its operation, contrary to the case with the level sensing devices conventionally used, such as float switches and electrical conductivity switches.
摘要:
The invention relates to a heating and cooling arrangement with which the occurence of sweat water at particular sites can be prevented. To this end a carrier (5, 6, 63, 80, 95, 120, 403-406) is provided in which is disposed a pipe or tube (4, 8, 161, 162, 194) system which transports a heating or cooling fluid. The temperature of the cooling fluid is given off to the carrier (5, 6, 63, 80, 95, 120, 403-406) and radiated into the room. Below the carrier (5, 6, 63, 80, 95, 120, 403-406) is located a sweat water channel (32, 46, 71, 81, 101, 102, 123, 187, 199) connected mechanically with this carrier (5, 6, 63, 80, 95, 120, 403-406). In order to achieve a thermal separation between carrier (5, 6, 63, 80, 95, 120, 403-406) and channel (32, 46, 71, 81, 101, 102, 123, 187, 199) a heat resistance (2, 3, 42, 43, 75, 87, 100, 90, 126-133, 155, 171, 181) with a given heat insulation value is provided between the two or the channel (32, 46, 71, 81, 101, 102, 123, 187, 199) is layed out so that it has on its underside a thermal insulator.
