This utility model relates to the field of cold storage equipment technology, specifically to a cold storage unit with an anti-frost structure. It includes a cold storage body, an anti-frost mechanism fixed to the outer wall of the body, extending into the inner wall of the body. The anti-frost mechanism comprises multiple anti-frost plates installed at a certain angle on the inner wall of the body. A spray mechanism is fixed around the outer wall of the body, extending into the inner wall and located at the top of the anti-frost mechanism. This utility model, through the cooperation of the internal components of the anti-frost mechanism, reduces condensation on the inner wall of the cold storage body and facilitates the drainage of water droplets adhering to the interior, thereby reducing frost formation. Furthermore, through the cooperation of the internal components of the spray mechanism, it increases the humidity inside the cold storage body, further reducing the probability of frost formation.

The application provides a partition plate, a compressor pump body, a compressor and an air conditioner. The partition plate is arranged between two adjacent cylinders. The partition plate comprises an axial first end surface and an axial second end surface. The axial first end surface and the axial second end surface are oppositely arranged. A first heat insulation hole is arranged in the interior of the partition plate. The first heat insulation hole is located between the axial first end surface and the axial second end surface and does not contact the axial first end surface and the axial second end surface respectively. In the axial direction of the partition plate, the first heat insulation hole is opposite to a first area between a suction hole of the cylinder and an exhaust hole. According to the application, heat transfer from the high-temperature side of the cylinder to the suction side of the cylinder through the partition plate body can be inhibited, the suction temperature rise of the suction side of the cylinder is reduced, the refrigerant suction amount is increased, and the compressor performance is improved.
