Description

Refrigeration device capable of controlling defrosting operation based on temperature difference The present invention relates to a refrigeration device capable of controlling a defrosting operation based on a temperature difference. A refrigeration system is a device that maintains the temperature of a space where it is installed at a desired temperature (typically low temperature) through phase and temperature changes by circulating refrigerant through an evaporator, compressor, condenser, and expansion valve back to the evaporator. As vaporization occurs in the evaporator of the refrigeration system, frost or ice forms on the evaporator, reducing the efficiency of the refrigeration system; therefore, a defrosting operation is performed to remove the frost or ice formed on the evaporator. Meanwhile, if a conventional refrigeration system is controlled with an emphasis on defrosting operation, the temperature of the space where the refrigeration system is installed may not be maintained at the desired temperature; conversely, if the control is controlled with an emphasis on maintaining the temperature of the space where the refrigeration system is installed at the desired temperature, temperature control for defrosting operation may not be smooth. FIGS. 1 and FIGS. 2 are drawings for explaining a refrigeration device capable of controlling a temperature difference-based defrosting operation according to an embodiment of the present invention. FIG. 3 is a diagram illustrating the principle of a refrigeration device capable of controlling a temperature difference-based defrosting operation according to an embodiment of the present invention. FIG. 4 is a diagram illustrating a system in which a refrigeration device capable of controlling a temperature difference-based defrosting operation and a wireless care device are integrated according to an embodiment of the present invention. Figure 5 is a drawing for explaining the wireless care device of Figure 4. FIG. 6 is a drawing for explaining a wireless care method according to an embodiment of the present invention. FIG. 7 is a diagram illustrating a method for estimating the type of a wireless device according to an embodiment of the present invention.
