Gas disturbance type low-temperature liquid

Abstract

The invention relates to a gas disturbance type low-temperature water chiller which comprises a water tank, a plate-shaped evaporator and an air pump, wherein the plate-shaped evaporator is soaked in the water of the water tank, a refrigerant channel is arranged in the plate-shaped evaporator, a water outlet pipe is arranged at the upper part of the plate-shaped evaporator, a water inlet pipe is arranged at the lower part of the plate-shaped evaporator, the water inlet pipe is provided with a water distribution hole, a gas header is installed below the water inlet pipe, a small hole is formed on the gas header, and the gas header is connected with the air pump through windpipes. The gas disturbance type low-temperature water chiller provided by the invention has the advantages that the air pump performs ventilation on the bottom of the water tank, the outer surface of the plate-shaped evaporator is not frozen by virtue of the air disturbance, and the problem of closed evaporator freeze spalling can be avoided; and the heat exchange efficiency of the plate-shaped evaporator is improved, and the low-temperature cold water at the temperature lower than 2 DEG C, and the demands on low-temperature cold water in other industries can be met.

Description

technical field [0001] The invention relates to an industrial chiller, in particular to a gas disturbance low-temperature chiller. Background technique [0002] The earliest industrial chiller refrigeration method for human beings is to use cold substances that exist in nature-ice, deep well water, etc. China has a history of using ice as early as the Zhou Dynasty. In the Qin and Han Dynasties, the use of ice went a step further. According to the records of "Yiwenzhi", there were five palaces in the Qin Dynasty, with crystal pillars and arches, called the Crystal Palace. This is essentially the earliest air-conditioned room in China. In the Tang Dynasty, iced drinks were produced and there were ice merchants. Ice cream and milk ice also originated in China. The prototype of ice cream was brought to Europe by the famous Italian traveler Marco Polo during the Yuan Dynasty. [0003] Artificial refrigeration has a history of more than 100 years in the world. The old Chinese...
