Snow making system for performance testing device of freezer

Abstract

The invention relates to a snow making system for a performance test device for a freezing and refrigerating cabinet. The snow making system comprises a water and vapor mixing and spraying-out unit, a water tank and an air compressor for supplying compressed air for the water and vapor mixing and spraying-out unit. A water outlet and a snow making water supply opening are formed in the bottom face of the water tank. A water inlet is formed in the side face, away from the water outlet and the snow making water supply opening, of the water tank. The water tank communicates with an air-cooled chiller unit through the water outlet and the water inlet to form a water-cooling circulating loop. The snow making water supply opening communicates with the water and vapor mixing and spraying-out unit. According to the snow making system, water in the water tank flows from top to bottom, the water with the low temperature flows into the water inlet and is mixed with the water in the water tank, the longer the mixing process is, the more uniform the temperature cooling is, and therefore a snow making water region with the most uniform and constant temperature is formed naturally in the bottom region of the water tank, meanwhile it is avoided with an eddy is formed in the water tank and consequently the heat is lost, the stable snow making water temperature is guaranteed, the snow making density is increased and the snow making efficiency is improved.

Description

technical field [0001] The invention belongs to the field of performance test devices for refrigerated cabinets, and in particular relates to a snowmaking system for a performance test device for refrigerated cabinets. Background technique [0002] As the use of refrigeration and refrigeration becomes more and more extensive, the performance effects of various refrigerators and refrigerators have attracted more and more attention. Therefore, the device system for performance testing of refrigerators and refrigerators is also particularly important, and the performance test device system Snowmaking system is the top priority. [0003] The freezer directly exchanges heat with the external environment. The external environment has a great influence on the operating performance and service life of the freezer. In order to determine whether the freezer can operate normally and its cooling To determine the relationship between the ability and the external environment, and whether...

AI Technical Summary

Problems solved by technology

However, due to the large volume of the water tank and the lack of temperature sensors, it is easy to cause temperature stratification inside the water tank, and the unevenness of the water temperature greatly affects the snowmaking effect, such as low snowmaking density and low efficiency.
