Description

Refrigeration plant and evaporimeter
The present invention relates to a kind of refrigeration plant, particularly housed device, it has inner space and evaporimeter.When described evaporimeter was supplied cold-producing medium, the temperature on the surface of this evaporimeter reached far below 0 ℃.Therefore airborne moisture in the refrigeration plant inner space understood condensation and be frozen on the surface of evaporimeter.This can cause forming ice sheet on the surface of evaporimeter, and this ice sheet needs regularly to melt to remove.Under the situation of freezing equipment, ice sheet also usually expands to sidewall and internal instruments for example on frozen goods drawer and the intermediate shelf from evaporator coil, and can only be by whole refrigeration plant is defrosted and could remove from it.
For those so-called frostless refrigeration plants, evaporimeter is disposed in the evaporimeter room that separates with the inner space.The fan that is arranged in the described evaporimeter room is transported to the room (inner space) that is used for frozen goods by means of air duct with the dry air that cools off.Airborne moisture and smell substance are condensate on the evaporimeter and at this and form frost layer or ice sheet.Defrost timer is closed fan with particular time interval, and connects the heater that is attached to evaporimeter.Therefore evaporimeter is defrosted, and frozen goods is not melted.Defrost heater, and the long-term operation of fan, the energy consumption that means such equipment is far above the metric system cool equipment.
Being provided with the evaporimeter that is used for refrigeration plant of detesting water type coating can learn from WO 03/106902.Such coating is used to postpone initial ice crystal in the formation of not having on the ice evaporimeter, thereby prolongs the time of freezing once more on evaporimeter after the defrost operation.Yet,, detest water type coating and just can not prevent or slow down further icing in case ice sheet exists.
WO 2008/025538 has described a kind of known antiscale coating, and it is molded on the sharkskin and prevents and for example adheres to crustacean on the shell.
This coating comprises flexible surface and micro-structural.The document has been described when crustacean long when too big, will come off from coating.About other field of adopting this coating comprises for example milk processing, brewages and papermaking, prevent the formation of organic sediment in this hope.Yet relevant document does not provide any prompting and utilizes the coating of expectation to reduce adhering to of ice.
The evaporimeter that the objective of the invention is to propose a kind of refrigeration plant and be used for refrigeration plant, wherein, ice is in evaporimeter and other lip-deep growth of inner space or can be reduced or prevent adhering to of ice.
This purpose can realize like this that promptly at least one section of evaporimeter is provided with micro-structure surface, and it reduces ice growth and/or the adhering to of ice from the teeth outwards.Evaporimeter preferably is constructed to finned evaporator.
The principle of having confirmed WO 2008/025538 among the present invention not only is applicable to organic sediment, but also is very suitable for growing on the anti-evaporimeter of stagnant ice in the refrigeration plant inner space.The micro-structural on surface means that when ice becomes too big, it will come off from evaporimeter or micro-structure surface.This makes that refrigeration plant can be with more energy-efficient realization, because defrosting cycle no longer needs, or its frequency can reduce.The present invention is useful especially in frostless equipment, because the growth of ice is confined to the evaporimeter place.If described evaporimeter is provided with micro-structure surface of the present invention, can fully phase out defrosting cycle alternatively.Therefore evaporimeter preferably is arranged in the evaporimeter room that separates with the inner space in the outside, inner space, and described evaporimeter room is connected to the inner space by means of air duct.Therefore whole disclosures of WO 2008/025538 are incorporated among the application.
Micro-structural is preferably formed by protrusion in the surface and depressed part, and they can have highly is 1-2mm, and distance is up to 1-2mm each other.Protrusion and depressed part can form with rule or irregular mode; Under the situation of irregular distribution, micro-structural can also be formed by roughened textures, the roughness R of roughened textures aCan be up to 1mm.Perhaps, the average surface roughness R with the degree of depth (peak valley height) expression of micro-structural zBe preferably about 20 μ m to 2mm.
The section of evaporimeter especially preferably has micro-structure surface, because the most serious icing occurring on the evaporimeter.Yet, also advantageously, if particularly evaporimeter is arranged in the inner space, can be other surface of inner space, at least be at some section, micro-structure surface of the present invention is set,, perhaps makes so that freezing of these places also can reduce, in case ice pellets reaches certain size, formed ice comes off with regard to oneself, or comes off by rapping, and does not need defrosting.Have cold wall evaporimeter for example under the situation of rear wall evaporimeter at refrigerator, for example, at least one section of the wall of inner space (arranging evaporimeter thereafter) is provided with such surface.In addition, the utensil in the inner space is the interior wall of frozen goods drawer and refrigeration plant for example, can advantageously be provided with such micro-structure surface, so that any ice sheet that may form thereon can easily be removed.Particularly preferably, drawer and the interior wall that is combined in the ice machine in the refrigeration plant is provided with micro-structure surface of the present invention.
Refrigeration plant is preferably housed device, particularly refrigerator, refrigeration plant or combination freeze/refrigeration plant.
Micro-structure surface is preferably distributed in the coating especially, and this figure layer puts on the wall/utensil of evaporimeter or inner space.This makes the protrusion of micro-structural and depressed part advantageously be formed by coating material, and this can obtain attendant advantages extraly, for example can produce low-surface-energy.
According to a preferred implementation, micro-structure surface still is an elasticity or flexible.The elasticity on surface makes that its ice sheet of go up growing can more easily be removed or come off, in some cases by means of ice sheet self.The elastic modelling quantity of micro-structure surface is preferably about 0.01-1kN/mm 2
Micro-structural is preferably formed by lip-deep protrusion and depressed part, protrusion be elastically deformable or can relative to each other be offset with elastic type.For realizing this point, the material of protrusion can be correspondingly flexible, has for example Durometer A hardness 30-40.Perhaps, protrusion also can be formed by the particulate of introducing in the flexible material, and particulate can relative to each other be offset with elastic type in flexible material.The tip of protrusion preferably can relative to each other be offset and be up to about 20 to 100 μ m.This makes and to grow into when being resisted against other ice pellets when each ice pellets that the growth of ice pellets has produced gravitational effect.This can cause one or two ice pellets to break away from micro-structure surface and come off.
Micro-structure surface also preferably has low-surface-energy, and water-wet is arrived than low degree so that it can only be condensed.This means that ice forms the slowly ice pellets of growth, because micro-structure surface of the present invention, described ice pellets will come off when becoming too heavy or being resisted against adjacent ice pellets.The surface of micro-structure surface can preferably be lower than 0.04 joule/m 2, preferably be lower than 0.03 joule/m 2, be preferably 0.020-0.025 joule/m especially 2
Therefore and low degree ground is wetted as far as possible micro-structure surface also is preferably detests the water type, so that ice attached thereto and water are the least possible, and the surface.Detest that water type characteristic is preferred to be realized like this, promptly surface or coating by material for example polymer etc. form.
Micro-structure surface is preferably formed by protrusion and depressed part, and they are with rule or irregular mode profile.Under the situation of scramble pattern, protrusion and depressed part can also be taked the form of macro-asperity, its mean roughness R aBe preferably 50-500 μ m.
