Whenever the door of refrigerating plant when opening, the air of heat can enter in the inner space of refrigerating plant and cool off after closing door and produce low pressure.This low pressure causes door to be very difficult to open after closing again, up to the pressure between inner space and the surrounding environment once more till the balance.In order all to open door at any time easily, the someone proposes to install pressure equalisation valve additional in the housing wall of this device, in the inner space, exist under the situation of low pressure, this can make that air is delivered to inside from the outside, in case and the pressure between surrounding environment and the inner space is balanced the transmission that just stops air, make to prevent that outside pressure equalization stage heat and moist extraneous air from entering in the inner space uncontrollably.
Test shows that this pressure equalisation valve must have big diameter, so that can carry out isostasy apace in obvious muting mode.This pressure equalisation valve is weakness in the thermal insulation of refrigerating plant, and wherein, the input hot-fluid that enters in the inner space enlarges markedly along with the diameter of pressure equalisation valve.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of housing that is used for refrigerating plant with pressure equalisation valve, described pressure equalisation valve can make on the one hand and noiseless or carry out isostasy with low-down noise at least prevent to flow into via the tangible heat of pressure equalisation valve but then again.
Above-mentioned purpose realizes by following feature: be used for the housing of refrigerating plant, pressure equalisation valve is contained in described housing in the pipeline of wall of housing, and described pipeline is provided with the breathable cover cap at least one side of wall.This cover cap can not disturb isostasy, and the air slowly that convection current produces flows yet it prevents again particularly.Owing to prevent this flowing in the position of pressure equalisation valve, therefore slack-off and were it not for air and flow through pressure equalisation valve with the heat exchange meeting of surrounding environment, the air between pressure equalisation valve and the cover cap serves as the additional thermal insulation layer.
According to a preferred embodiment of the invention, cover cap is a grid.
Alternatively, cover cap also can be the plate that covers pipeline, and described plate is retained at this moment away from the wall that holds pressure equalisation valve, so that do not disturb air from the inflow of pressure equalisation valve and/or from the outflow of pressure equalisation valve in the isostasy process.
Cover cap can be provided with the standing part that is bonded in the opening.
Cover cap preferably is attached to the inside of wall.If cover cap is attached to the outside, this situation can appear: break dew point by a fall between cover cap and pressure equalisation valve, make condensed water be deposited continuously.Under cover cap is positioned at situation on the inside, do not have this danger, this be because the zone this moment between pressure equalisation valve and the cover cap than the inner space heat that is communicated with it.This has also reduced at isostasy process hollow gas and has flowed in the housing and the trend of pressure of freezing wall balanced valve.
If air duct extends in comprising the wall of pressure equalisation valve, particularly for the storage chamber of housing and the air exchange between the evaporimeter chamber, the cover cap of pressure equalisation valve can owing to it be integrated in be designed in the framework around the opening of passage very unshowy.
Framework also preferably includes the grid of the opening that covers air duct.
Pressure equalisation valve is preferably mounted in the door of housing, and this is because to be drawn into the possibility of the hot-air in the inner space minimum there because of the used heat of refrigerating plant in the isostasy process.
Pressure equalisation valve can easily be formed by the flexure strip that is contained in ducted bending (geknicktes), and the flexure strip of described bending has by touching the edge on the inwall of pipeline.
