Product Configuration
Among various defrosting methods, electric heating defrosting is widely adopted due to its simplicity and effectiveness. Specifically, the evaporator defrost heating element heater converts electrical energy into heat energy to directly heat the fins of the cold air blower.When the temperature of the fins rises, the frost layer melts and falls off due to the heat, thereby restoring the normal heat exchange capacity of the equipment.The advantages of this method (evaporator defrost heater element) lie in its relatively simple structural design, which is convenient for installation and maintenance.In addition, its operation process can be easily automated, such as setting the start conditions through a timer or temperature sensor to ensure that the defrosting process occurs at the appropriate time and avoid unnecessary energy waste.
The cold room/cold storage defrosting heating elements in the evaporator, as one of the core components of the refrigeration system, directly affect the overall operational efficiency of the system.To prevent frost formation on the fins from causing damage to the equipment, these defrost heater elements must be able to start promptly and provide sufficient heat to melt the frost layer.At the same time, reasonable control of the heating duration and temperature is also crucial. If the heating time is too long or the temperature is too high, it may cause damage to the fin material;Conversely, if the heating is insufficient, the frost layer cannot be effectively removed.Therefore, by precisely controlling the start frequency and heating intensity of the direct heating defrosting heater, not only can the good functional state of the equipment be maintained, but also the temperature regulation effect can be optimized, further enhancing the overall performance and service life of the refrigeration system.
