Preparation device for refrigeration water energy-saving for production

Abstract

The invention relates to a preparation device for refrigeration water energy-saving for production, belonging to the mechanical field. The outdoor low temperature environment is utilized for refrigeration and cold is accumulated in off-peak hours when prices are low, thus the boot time of the refrigerator can be reduced, the electric energy can be saved and the equipment loss can be lowered. The preparation device comprises a mechanical refrigerator, a cold water tank, a heat exchanger in the refrigeration production link, a water pipeline, a backwater tank and a water pump on the water circulation pipeline. The invention has the following improvements: a cooling tower is added between the refrigerator and the cold water tank; a sinuous coil is added in the backwater tank; the both ends of the coil are connected with an ammonia tank or a refrigerator refrigerant tank; and the ammonia inlet end of the coil is provided with a valve and the ammonia backflow end is provided with an ammonia compressor. The invention has the following beneficial effects: the temperature of the refrigeration water can be reduced by utilizing the natural environment, thus greatly reducing the consumed electricity; the coil communicated with the refrigerant is arranged on the backwater tank for cold accumulation, thus the electric charge can be reduced; and the added structures have mature technologies, are easy to operate and are reliable, safe and environment-friendly to run.

Description

technical field [0001] The invention belongs to the field of mechanical technology, Background technique [0002] In the production of some products, it is necessary to use cold water to cool down one or several process links. For example, in the production of dairy products, raw milk is temporarily stored at low temperature, cooled after dissolving additives, and cooled after fermentation. The existing cold water refrigeration device includes a cold water (or ice water) mechanical refrigerator, and a cold water tank connected to the refrigerator. , the heat exchanger (or heat exchange unit) in the refrigeration production link, the cold water delivery pipeline connecting the cold water storage tank and the heat exchanger, the return water pipeline connecting the water outlet of the heat exchanger and the refrigerator, and the return water pipeline It consists of a water return tank and a water pump on the water circulation pipeline. In most manufacturers, the cooling wate...

AI Technical Summary

Problems solved by technology

In most manufacturers, the cooling water is used continuously for a long time, resulting in long start-up time of the refrigerator, high energy consumption, large equipment loss, and a high proportion of the cooling part in the production cost of the product.

At present, no technical solutions have been proposed to produce cooling water in cold regions and use the climate environment to reduce the start-up time of refrigerators, and use the difference in peak-shaving electricity charges to reduce cooling electricity expenses, ignoring the opportunity to save energy and reduce production costs
