An embodiment of the present utility model, as shown in fig. 1 to 8, provides a refrigeration system and a refrigeration apparatus.
An embodiment of an aspect of the present utility model, as shown in fig. 1, 2 and 3, provides a refrigeration system 100, which includes an evaporator 1, a water pan 2 and a heater 3, wherein the water pan 2 is disposed below the evaporator 1, an air return port 21 is formed on the water pan 2, the heater 3 is disposed between the evaporator 1 and the water pan 2, and a distance H between the heater 3 and the air return port 21 is less than or equal to 20mm.
It will be appreciated that the evaporator 1 is part of a refrigeration cycle and is primarily responsible for absorbing heat from the condenser and transferring it to the refrigerant. As the refrigerant passes through the evaporator 1, it changes from a liquid state to a gaseous state and absorbs heat around the evaporator 1, resulting in a decrease in the surface temperature of the evaporator 1. Thus, the evaporator 1 can absorb heat from the inside of the refrigeration compartment to keep it in a low temperature state. In this way, the air in the freezer and refrigerator compartments is cooled and the food and items are kept fresh.

The heater 3 can be used on the one hand for removing frost on the surface of the evaporator 1 and on the refrigeration line. When the door of the refrigerating apparatus is opened, hot air enters the inside of the refrigerating apparatus, and water vapor therein may frost on the surface of the evaporator 1.
