Estimating the term…
The icing of the evaporator for refrigerant in a refrigeration system is checked by an air-permeable web of wire mesh which is moved along an endless path extending in front of the inlet of the evaporator to collect moisture from the flow of atmospheric air which is conveyed into the evaporator. Successive increments of the web are thereupon regenerated by melting or mechanically removing the ice and frost and by thereupon drying and cooling the increments before they return into the portion of the endless path in front of the inlet of the evaporator. Cooling of the web can be effected in a discrete cooling device or by causing a portion of the path to extend behind the outlet of the evaporator so that the web is cooled by cool atmospheric air which leaves the evaporator. The moisture-collecting action of the web can be enhanced by causing several successive portions of the path to extend in front of the inlet of the evaporator so that moisture-containing atmospheric air must repeatedly penetrate through the interstices of the web before it enters the evaporator.
A method of checking the icing of the evaporator for refrigerant in a refrigeration system wherein the evaporator has inlet means for admission of a flow of atmospheric air and such air normally contains moisture, comprising the steps of repeatedly conveying across the flow of atmospheric air in front of the inlet means of the evaporator a moisture-collecting air-permeable body which collects at least some moisture from the flow while the flow passes therethrough and into the inlet means whereby the collected moisture tends to freeze on the body;
