The evaporator is an important component of the four major parts of refrigeration systems. The low-temperature condensed liquid passes through the evaporator, where it undergoes heat exchange with the external air, vaporizes, and absorbs heat to achieve refrigeration.

The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing it to boil and vaporize; the evaporation chamber separates the gas and liquid phases completely.

Evaporator 1: A metallic round bowl with an internal diameter of φ200mm and a height of approximately 100mm.

2. The evaporator is a metallic round structure; the inner wall should be smooth, and the blade edge of the evaporator must not have burrs or scratches, etc.

All parts in contact with water should be smooth, and the welds in their mating or connecting sections should be tight and solid, with no leakage.

4. The assembly of evaporator components should be correct, with no loose parts, deformation, or other defects affecting use.

5. The protective coating on all parts of the evaporator should be firm, even, and smooth, with no peeling or rusting defects.

6. The evaporator and installation frame should be easy to install, and ensure that the evaporator does not become dislodged due to wind influence during normal operation.
