Abstract
The evaporator for a refrigeration device is provided with a hydrophobic coating on the surface thereof, in order to inhibit the icing of the evaporator during operation and to reduce the generation of noises arising from relative displacements between the evaporator (4) and the ice (3) attached thereto.
Description
Technical field
The present invention relates to a kind of evaporimeter that is used for refrigeration plant.
Background technology
When the supply cold-producing medium, this evaporator surface temperature can reach and be lower than 0 ℃.Therefore can on evaporator surface, condense and freeze from the atmospheric moisture of the inner room of refrigeration plant.Form at first on evaporator surface wherein that one deck is very thin, equally distributed frost layer, do not melted during this period,, be gathered into firm, hard ice sheet at last along with the running of refrigeration plant will constantly thicken as the bloom layer.Because the temperature of evaporimeter changes in time, by its supply system cryogen and decide whether, this ice sheet can periodically expand and contraction again in time.Wherein between ice sheet and the evaporimeter below it, form tension force, finally cause the landing of ice sheet pulsed.The noise made in coughing or vomiting warbling of the oriole noise of drawing thus forms and disturbs.
Summary of the invention
The objective of the invention is, design a kind of evaporimeter that is used for refrigeration plant, wherein noise made in coughing or vomiting warbling of the oriole noise is reduced.
This purpose is to solve like this, and the evaporator surface that may produce ice on it is provided with one deck hydrophobic coating.
According to the present invention, a kind of evaporimeter that is used for refrigeration plant is provided, have that a pipeline that is used for cold-producing medium can be connected with pipeline with heat conduction with one and as the surface of a heat-transfer surface, wherein be provided with the hydrophobic oil reservoir of one deck as the surface of a described heat-transfer surface at least.
Such coating is used for, and postpones the formation of the crystalline solid of ground floor ice on the evaporimeter that does not have ice and so prolongs the time that needs, and up to assemble the ice group after the melting process on evaporimeter, these enough cause noise made in coughing or vomiting warbling of the oriole noise.The another effect of hydrophobic coating is that the device surface that avoids evaporating forms frost layer uniformly.But form inevitably a small amount of freezing at evaporator surface.The ice pearl that the there forms roughly increases equably on the surface that their are assembled and reaches suitable thickness before they begin to assemble.That is, formation can be assembled a large amount of ice group who compares with the evaporimeter that does not have hydrophobic coating before can making the relevant ice sheet that produces noise made in coughing or vomiting warbling of the oriole noise on evaporimeter according to the present invention.
The another advantage of the isolated growth of ice sheet is, the zone, surface of evaporimeter can keep not having the ice state relatively for a long time, and between refrigeration plant and environment, also therefore can carry out effective heat exchange, and a considerable amount of ice have been assembled in other zones of evaporator surface this moment.Comparing and therefore to prolong in the time interval between twice melting process and the evaporimeter that does not have hydrophobic coating, this is for the user of configuration according to the refrigeration plant of evaporimeter of the present invention, increased comfortableness, reduced energy resource consumption and reached by the production cost due to it.
Hydrophobic coating preferably silicones as the composition that produces hydrophobic effect.
This coating can be coated with the enamelled coating that solidifies or the form of oil reservoir.Wherein oil reservoir especially has advantage, because oil itself is not solid-state, so it has promoted the mobility of the ice pearl that forms on the evaporator surface, and when being frozen fully, evaporimeter has certain bed thickness, this enough produces noise made in coughing or vomiting warbling of the oriole noise in traditional evaporimeter, and in evaporimeter according to the present invention, cut down, because needn't produce the hot tensile strength of the very big noise made in coughing or vomiting warbling of the oriole of very strong initiation noise makes between ice shell and evaporimeter and relatively moves, and general very little tension force enough makes ice sheet landing from the evaporimeter, or may even realize ice sheet continuous sliding on evaporimeter.
Evaporimeter according to the present invention is preferably designed to plate evaporator, is fit to be applied to air cooling refrigeration equipment or freezing equipment.
Description of drawings
Accompanying drawing has been showed a sketch when freezing according to plate evaporator 4 parts of the present invention.
The specific embodiment
Plate evaporator 4 comprises a pipeline 1 that is used to flow through cold-producing medium.Around the outer surface scroll of pipeline 1 ground around a thin slice 2.The surface of thin slice 2 has constituted a heat-transfer surface, and the outer surface of the pipeline 1 of installation thin slice 2 has formed another heat-transfer surface.These heat-transfer surfaces of plate evaporator dispose the hydrophobic coating of being made by silicone oil.
Because the hydrophobicity of coating needs a lot of energy to come the surface of moistening plate evaporator 4, when liquid was frozen into ice on the surface, these energy must discharge.This is a very big obstacle for forming the ice pearl more from the teeth outwards.Therefore the moisture supersaturation in air-flow, quite a few moisture in the air-flow of the plate evaporator of flowing through can not be condensate on the plate evaporator 4 voluntarily, and for no other reason than that moisture does not run into from the energy is the surface that helps build-uping ice.Therefore when plate evaporator is installed in air cooling refrigeration equipment or the frostless refrigeration plant, can make the air in the inner room of refrigeration plant only produce a spot of drying, be to be worth pursuit fully for responsive food of storage such as vegetables that some are fresh like this.
Make atmospheric moisture condensation on plate evaporator, must have such surf zone, help condensation from the energy thereon.Most of condensation starting points show as such zone, dust granule, the surperficial point of interruption or this class, this is inevitably to exist on the plate evaporator surface, but only forms in very little part.On these condensation starting points-as shown in Figure 1-a lot of little ice pearl 3 of formation in the plate evaporator operation process.Airborne moisture preferential continuation on the surface of these ice pearls 3 around plate evaporator 4 condenses, ice pearl 3 increases thickness and diameter in time like this, yet some zones between the ice pearl, evaporimeter 4 surfaces keep long-time not ice, and can carry out effective heat exchange between the cold-producing medium of circulation in plate evaporator 4 and surrounding air.
