Summary

This paper proposes a type of ejector throttling refrigeration system (Mode III), and compares it with traditional thermal expansion valve (Mode I) and liquid pump for liquid (Mode II) through experiments. The effects of these three liquid supply modes on freezing time of food, freezing temperature difference and total energy consumption of freezer are studied experimentally. The results show that under the experimental conditions,the freezing time of Mode II & III is shorter by about 14% than Mode 1, the falling of food' s temperature is more evenly, and it is good for enhancing the quality of food freezed. On the aspect of energy consumption, Mode III saves 6. 3% than Mode 1, and saves 9.6% than Mode II. Therefore, the advantages of liquid supply with ejector throttling are obvious.
