Abstract

The invention relates to an ethylene glycol coolant circulating system which comprises a refrigerating machine, a heat exchanger, a coolant tank, a control system, a PH transmitter and an alkali solution storage tank, wherein a solution output tube of the alkali solution storage tank is connected to a main transmission tube which is communicated with the coolant tank, the PH transmitter is installed on the coolant tank, a signal collected by the PH transmitter is transmitted to the control system, and a filling pump is installed on the main transmission tube. Acidic corrosion after oxidization of the coolant can be effectively avoided.

Description

technical field [0001] The invention relates to a circulation system, in particular to a circulation system using ethylene glycol as a refrigerant. Background technique [0002] Ethylene glycol is easily mixed with water and many other organic compounds, and is the most commonly used organic solvent refrigerant. Ethylene glycol is colorless, odorless, weak in volatility and low in corrosiveness. In the existing refrigerating cycle system, it is first necessary to exchange heat with the ethylene glycol aqueous solution through the refrigeration equipment, that is, to lower the temperature of the ethylene glycol aqueous solution, and then let the low-temperature ethylene glycol aqueous solution exchange heat with other media to be cooled, thereby To achieve the purpose of cooling. Compared with other refrigerants used as refrigerants, ethylene glycol has the characteristics of moderate price, high boiling point, excellent performance, and easy availability of raw materials. ...
