Abstract
The refrigerating evaporator features that its surface is coated with a layer of high hydrophobic material for making it do not frost during temp holding stage, resulting in stable temp, saving energy and keeping a certain humidity.
Description
The present invention relates to Refrigeration Engineering, relate to refrigerating evaporator more precisely.
Existing evaporimeter, because its surface temperature is lower than the water spot temperature of water vapour in the humid air, and is lower than triple point of water, the frosting so the water vapour in the humid air will be sublimated on the cold surface of evaporimeter, the frost layer will thicken in time.Even to this day, frosting that we can say refrigerating evaporator is the great technical barrier of the Refrigeration Engineering midium or long term failing to solve well always.
In order to solve the refrigerating evaporator frosting, the method that prior art is taked mainly is that regularly evaporator surface frosting layer to be melted with hot gas or electrical heating be water, then water is discharged.Its problem is 1) when hot gas or electric defrosting, temperature of ice house will produce than great fluctuation process; 2) will expend a large amount of energy when hot gas or electric defrosting; 3) poor to the moisture retention of freezer frozen food.
The purpose of this invention is to provide a kind of refrigerating evaporator that can suppress frosting effectively.
Technical scheme of the present invention is to realize like this.
A kind of refrigerating evaporator is characterized in that in its surface, scribbles one deck high-hydrophobic material equably.
The thickness that is coated in the high-hydrophobic material on the refrigerating evaporator is 10～25 μ m.
Said high-hydrophobic material is a polytetrafluoroethylene (PTFE).
Good effect of the present invention:
Can keep the evaporimeter frost-free at holding stage; Thereby make the storehouse temperature stable, energy-conservation; The food moisture retention is good.
Be described in further details below in conjunction with embodiments of the invention.
Be coated with last layer polytetrafluoroethylene (PTFE) (embodiments of the invention adopt spraying plating to realize) on the former evaporimeter of refrigerator-freezer, its thickness is 20 μ m, Q=107 ° of its contact angle.The temperature maintenance of its refrigerator-freezer is at-10 ℃, and φ=50%HR is as long as the evaporating pressure of cryogen guarantees that evaporimeter cold surface temperature a little more than-21.5 ℃ (for example-20～-21 ℃), just can make the evaporimeter frost-free in the control evaporimeter.
Claims (3)
1. a refrigerating evaporator is characterized in that scribbling equably in its surface one deck high-hydrophobic material.
2. according to the described refrigerating evaporator of claim 1, the thickness that it is characterized in that being coated in the hydrophobic material on the refrigerating evaporator is 10～25 μ m.
According to the described refrigerating evaporator of claim 1, it is characterized in that said high-hydrophobic material is a polytetrafluoroethylene (PTFE).
