Three, summary of the invention:
Purpose of the present invention provides a kind of sub-zero temperature Celsius frostless air-cooler, and it can make air-cooler under sub-zero temperature operating condition Celsius, and no matter how high humidity is in the storehouse, the air-cooler evaporator surface does not have the frosting phenomenon, need not the operation that defrosts, guaranteed the refrigeration of air-cooler, saved energy consumption freezer.
For achieving the above object, the technical scheme that the present invention takes is: be on the air-cooler basis of cold-producing medium commonly used at present direct vaporation-type in evaporimeter, set up the demisler that spills the low freezing point conductive fluid to evaporator surface cloth, promptly include the air-cooler of cold-producing medium direct vaporation-type in evaporimeter, air-cooler is provided with demisler.Described demisler includes fluid storage tank, liquid distributor, circulating pump etc., is placed with the low freezing point conductive fluid in the fluid storage tank.Fluid storage tank is communicated with liquid distributor by circulating pump, and liquid distributor is arranged on the upside of air-cooler evaporimeter, and fluid storage tank is arranged on the downside of evaporimeter.
During its work, provide cold wind by air-cooler to freezer, demisler dehumidifies to the evaporimeter of air-cooler, and its process does not increase invalid energy consumption.The circulating pump of demisler is delivered to liquid distributor with the low freezing point conductive fluid in the fluid storage tank, by liquid distributor the surperficial cloth of evaporimeter is spilt the low freezing point conductive fluid, and the moisture that condenses in evaporator surface is removed immediately, reaches the situation of the frostless operation of air-cooler.The low freezing point conductive fluid is stored in the fluid storage tank behind the absorption portion cold when removing evaporator surface moisture, and when refrigeration plant stopped cooling, conductive fluid was arranged the cold of its storage in freezer again.
Described air-cooler is cold-producing medium direct air-cooler of vaporation-type in evaporimeter, comprises wall-hanging, console mode, ceiling mounting type, top air-out formula, air-out type etc. down.
Described low freezing point conductive fluid, kind is a lot, can adopt salting liquid or anti-icing fluid etc.
The version of described liquid distributor is also a lot, can be the pipe that is provided with a plurality of apertures.
Described fluid storage tank is provided with overflow pipe, conductive fluid concentration adjuster.When conductive fluid when removing evaporator surface moisture, also moisture is brought in the fluid storage tank and continuous dilution conductive fluid, can add the higher conductive fluid of concentration by conductive fluid concentration adjuster, to adjust the concentration of conductive fluid in the fluid storage tank, when conductive fluid reaches certain liquid level in the fluid storage tank, can emit from overflow pipe.
For more effectively frost prevention, the frost prevention net can be arranged in the arranged outside of evaporimeter, liquid distributor spills the low freezing point conductive fluid to evaporator surface and frost prevention screen cloth.
Because the present invention is on the air-cooler basis of cold-producing medium direct vaporation-type in evaporimeter, set up demisler, demisler is sprinkled upon the moisture that will condense on the evaporator surface at any time on the evaporator surface with the uniform cloth of low freezing point conductive fluid and takes away, and has fundamentally prevented the frosting of evaporator surface.It is different from existing defroster fully, and existing defroster is just to defrost after the evaporator surface frosting.Therefore, the present invention has can make air-cooler under sub-zero temperature operating condition Celsius, and no matter how high humidity is in the storehouse, the air-cooler evaporator surface does not have the frosting phenomenon, need not the operation that defrosts, guaranteed the refrigeration of air-cooler, and saved characteristics such as energy consumption maintenance storehouse temperature is stable freezer.
