摘要:
There is provided a water feed device for humidification, comprising: an outflow reservoir that is disposed above a humidifier for feeding water into the humidifier by way of a permeation and that is provided with an overflow dam for maintaining a level of the water in the outflow reservoir substantially constant; an inflow reservoir that is disposed upwards of the outflow reservoir and that is provided with a flow inlet; a partition plate that is disposed between the inflow reservoir and the outflow reservoir; and a plurality of drip feed members which are provided in the partition plate for allowing the water in the inflow reservoir to drop by gravity in a form of droplets into the outflow reservoir. There is also provided an air conditioning apparatus having a dehumidifier, a heater, a humidifier and an air blower successively arranged within an air duct connect to an area to be air conditioned; downwards of respective portions of the cooling dehumidifier unit and the humidifier unit in the air duct there are provided a pair of water proof trays, respectively, which are communicated via respective hoses with the cooling dehumidifier unit and the humidifier unit, respectively, and which are provided with a drainage means that is opening to an outside of the housing; and downwards of the water proof trays and downwards of the air duct there is provided a further water proof tray having a drainage means that is opening to an outside of the housing.
摘要:
Apparatus and method for operating solution heat with vertical heat exchangers by providing an improved heat exchangers design and method for exchanging heat between a waste heat source and a binary working fluid preferably in an absorption heat pump unit and in particular the desorber section thereof.
摘要:
A falling film heat exchanger having a plurality of tubes is provided with a liquid distribution member surrounding each tube which directs liquid against the tube external wall to control the falling film flow and to form uniform films on each tube. The liquid can be a feed liquid or a heat exchange liquid such as a refrigerant.
摘要:
A heater exchanger used to condense a refrigerant in a refrigeration system. The heat exchanger is designed to perform a heat exchanging operation by the use of latent heat of water vaporization, thus having improved heat exchanging efficiency as well as a reduced size. The heat exchanger includes an upper header having a refrigerant inlet port and distributing a refrigerant introduced into the upper header through the refrigerant inlet port, a plurality of heat exchanging tubes connected at upper ends thereof to the upper header and extending in a vertical direction, a lower header connected to lower ends of the heat exchanging tubes and gathering the refrigerant flowing from the heat exchanging tubes, with a refrigerant outlet port formed in the lower header, and a water supply unit assembled with upper portions of external surfaces of the heat exchanging tubes, and feeding water to the tubes to cause water to flow along the external surfaces of the tubes. The water supply unit is a channeled body with the heat exchanging tubes perpendicularly passing the channeled body. The interior of the water supply unit is partitioned into a pressure regulating chamber and a water supply chamber by a partition wall having a plurality of pressure regulating holes. The pressure regulating chamber receives water from the outside, while the water supplying chamber feeds water to the heat exchanging tubes to cause water to flow along the external surfaces of the heat exchanging tubes. A plurality of lower holes are formed at a lower portion of the water supply unit to allow the heat exchanging tubes to perpendicularly pass the water supply unit through the lower holes. Each of the lower holes has a size larger than a cross-sectional size of each of the heat exchanging tubes.
摘要:
Efficient two-phase refrigerant mixture distribution is accomplished in a falling film evaporator by use of a refrigerant distributor disposed internal of the evaporator shell which overlies the evaporator tube bundle and which internally causes said two-phase refrigerant mixture to be made available along essentially the entire length and across essentially the entire width of the tube bundle prior to the delivery of the refrigerant out of the distributor.
摘要:
A vertical shell and tube heat exchanger in which the tubes extend through oversized holes in a liquid distribution plate. Liquid flows through the holes and down each tube exterior surface as a falling film. A spacer or clip, desirably of wire, is placed in each hole around each tube to center the tube so that the film has a uniform thickness. The clip is self-locking and remains fixed securely in position.
摘要:
A falling film heat exchanger of the shell and tube type has the tubes positioned in concentric rings. A liquid distribution box is positioned above the tube upper ends. Short pipes extend downwardly from the box to feed liquid between the rings of tubes to distribute the liquid uniformly to the tubes. The box desirably rotates slowly. Also, the pipes desirably extend between upwardly extending tube ends so as to provide a uniform pool of liquid which overflows uniformly into the tubes.
