Description

DESCRIPTION A COOLER This invention relates to a cooler with increased cooling efficiency.

In coolers, the icing on the evaporator worsens the cooling performance. and reduces the energy efficiency of the cooler. evaporator heaters to remove or prevent this icing on the is used. These heaters use energy to remove icing. and at the same time, by raising the temperature of the environment, the cooler is negatively affects energy efficiency. time or temperature These heaters, which operate depending on their values, do not cause ice formation or ice thickness. does not work as connected. For this reason, the heaters are early or late, can work more or less than needed. Heater for the energy efficiency of the cooler Detection of icing and ice thickness on the evaporator before starting needs to be done. Icing and ice on the continuously cooled evaporator surface Different methods are used to determine the thickness.

With light, a method used to detect icing on the evaporator. In the icing detection method, light is sent to the evaporator surface. In the absence of frost, the light is reflected back from the evaporator surface.

Back reflection is detected by light sensors and the intensity of the light is measured.

In case of icing, the intensity of the light coming to the light sensor, the light on the ice decreases due to absorption and scattering by reflection from ice. icing This value, which is compared with the light intensity in the absence of it, is on the evaporator. It is used to understand how much icing there is. In this method The main problem faced is that ice is white, so its reflectivity is increase and the use of white colored lights in determining the ice thickness. is a disadvantage. Therefore, the icing is linear. cannot be detected. As a result, in the first case encountered efficiency drops. In the second case, the heater is more than necessary. can be operated and similarly, the energy efficiency of the cooler decreases.

American number US9328953 in the state of the art It provides the detection of icing on the evaporator in the document. system is defined.
