Abstract
Provided is an assembly for insulating substantially vertical runs of cooled surfaces (12) that are continuously or periodically exposed to air or another gas that has a dewpoint temperature above that of the cooled surface, thereby resulting in condensation water vapor on or adjacent the cooled surface. One embodiment of the insulating assembly provides a wicking material layer (14) adjacent the cooled surface that, in combination with transporting and evaporating structures, removes the condensate from the vicinity of the cooled surface and allows for its evaporation into the ambient gas surrounding the exterior surface of the insulating assembly. Another embodiment provides for exposing the condensate to an internal conditioned gas stream to provide for evaporation that does not necessarily utilize an exterior surface. Both embodiments remove condensate from the insulating structure and thereby tend to avoid any substantial condensate accumulation and maintain the insulating performance.
Description
Technical field
The present invention relates generally to a kind of heat preserving method and a kind of insulating product equipment that pipe, pipeline or other surfaces are incubated, and may be continuously or periodically be cooled to below the temperature of surrounding air dew point in wherein said pipe, pipeline or other surfaces.More specifically, the present invention is about providing capillary heat preserving method of improved condensate and insulating product for the cold surface with basic vertical dimension.
Background technology
Usually, air-conditioning (HVAC) system comprises such as the such equipment of air conditioner unit, air channel and cold water pipe.Typically, for heat and/or acoustics purpose, these HVAC system units are incubated.The traditional insulation material that uses in the HVAC system comprises adhering to the finish coat on the heat-insulation layer and being installed into makes described finish coat away from air channel or cold water pipe location, promptly towards space orientation that parts passed.This layout trends towards reducing to be loaded with migration and the diffusion of the air of moisture to cold surface, and and then has reduced the formation of condensate.
Higher relative humidity and/or finish coat be damaged or incomplete situation under, can condense on the surface of the dew point of air by the insulation material diffusion and near temperature is lower than from the steam of surrounding air.When this condensing taken place, the thing that will be condensed of the interface between insulation material and the cold surface was wetting.
One or more layers finish coat is atresia typically, and as the barrier between thermal insulator and the external environment condition.But, as time goes by, and if especially as normal situation about occurring, described facing is damaged, and steam will be moved on the described cold surface and condensation on this cold surface.Condensate will be accumulated and will enter adjacent insulation material, thereby reduce its insulating efficiency.These problems are especially serious in vertical facilities, this be owing to condensate be tending towards along or contiguous vertical surface flow downward and cause in the lower part of vertical facilities and/or in horizontal component, excessively the building up of described facility.
Before to solving that condensate forms and one or more capillary materials have been used in the trial of the problem of removal in case the cold surface place or near the collection condensate, and this condensate carried away from this cold surface to one outer surface regions by one deck capillary materials.In case at insulation material outside or should the outside near, the condensate in the capillary material layer will be evaporated in the surrounding air.Though this method is fine for the facility effect of basic horizontal, but the condensate relevant with assembly that comprises significantly vertical surface or facility built up in the lower part that is tending towards causing condensate to accumulate in vertical facilities, and this accumulation will reduce the validity of this class scheme.
Summary of the invention
In order to solve the above problems, the invention provides a kind of insulating product of improved parcel insulation assembly, described insulating product is used to comprise the facility of the cold surface of vertical significantly or perpendicular.The present invention includes improved capillary materials so as to interrupt a plurality of parts place of cold surface or near the flowing downward of condensate of formation.Can be sent to the outer surface of insulation assembly or facility subsequently respectively by described insulation material from the described condensate of each several part.Transmit by flow path that repeatedly interrupts described condensate and the condensate that level is provided, the present invention can improve heat-insulating property, and minimizing damage and the deterioration relevant with the accumulation of condensate in the lower part of the vertical component of heat-insulation layer.
