AI Technical Summary

Technical Problem

Existing ice crystal evaporators are easily blocked by the cold medium during the refrigeration process, causing the circulation channels to freeze, resulting in equipment failure and high purchase costs. At the same time, the heat exchange efficiency is low and the volume is large, making it difficult to be widely used.

Method used

An ice crystal evaporator is designed, which is equipped with an S-shaped channel and separate water inlet and outlet in the tubular shell, and uses multiple guide partitions to divide the cavity to form a parallel circulation line for the cooled medium to avoid freezing and pass through the copper tubes or heat exchange tubes for efficient cooling.

Benefits of technology

It realizes the rapid flow of the cooled medium, avoids the problem of freezing, improves the refrigeration efficiency and energy efficiency, and is 4-5°C lower than the existing technology. It is suitable for chilling process and frozen meat processing, with small size and low failure rate. .

Abstract

The invention relates to an ice crystal evaporator and an ice crystal water cooling device producing from the same, belonging to the technical field of refrigeration. The ice crystal evaporator is characterized in that a liquid inlet channel is formed by an evaporator tube, a liquid inlet and a liquid outlet in a tubular casing; and the outer channel of the evaporator tube of the tubular casing is divided into more than one S-shaped channel forming a water return channel through a water inlet of a water divider and a water outlet of a water collector. The ice crystal water cooling device is characterized in that the return air inlet of the ice crystal evaporator is communicated with a compressor, a condenser, a liquid feeding valve, a dry filter, a liquid feeding electromagnetic valve anda thermostatic expansion valve in sequence, and then is communicated with the liquid inlet of the ice crystal evaporator; a cooling water inlet / outlet of the condenser is connected with a cooling tower in series; and a water inlet / outlet of the ice crystal evaporator is communicated with a water circulating pump and an ice crystal energy storage tank in series. The invention has the advantages ofhigh cooling efficiency, no icing and low cooling temperature and is suitable for production of energy storage central air-conditioning, marine fishing, seafood processing, fruit, vegetable or meat processing, and the like; the cooled medium is municipal water.
