Temperature description of glycol chiller

For users and friends, it is necessary to have a deep understanding of glycol chillers before use. It is recommended to know the temperature in various equipment such as refrigeration system, evaporating temperature, condensing temperature, etc.

If the refrigeration system of the glycol chiller can operate safely, three points need to be paid attention to:

1. The pressure of the refrigerant in the refrigeration system needs to be observed at any time to avoid abnormal high pressure, so as to avoid rupture;

2. The phenomenon of damp heat stroke and liquid shock shall not occur and occur, so as to avoid damage;

3. Pay attention to timely maintenance of each component, so as to avoid component defects and cause malfunction of the glycol chiller.

The evaporation temperature of a glycol chiller refers to the temperature at which the refrigerant in the evaporator inside the unit boils and vaporizes under a fixed pressure. The condensing temperature is the gas refrigerant in the condenser of the unit, and the temperature at which it condenses into a liquid under a certain pressure is called the condensing temperature. The recooling (or subcooling) temperature refers to the temperature at which the condensed liquid refrigerant is cooled to below the condensing temperature under the condensing pressure, which is called the recooling temperature (or subcooling temperature). The intermediate temperature of the glycol chiller refers to the two-stage compression system. The saturation temperature of the refrigerant in the intercooler at the intermediate pressure is called the intermediate temperature.

In fact, the temperature description of the glycol chiller is quite a lot. So how to detect the suction temperature and discharge temperature of the glycol chiller compressor after knowing these temperatures? The suction temperature of the compressor can be measured from the thermometer in front of the suction valve of the compressor. The suction temperature is generally higher than the evaporating temperature, and the difference depends on the length of the return pipe and the insulation of the pipe. Generally, it should be 5-10 higher than the evaporating temperature. The superheat can be adjusted by changing the liquid supply; The air temperature can be measured from a thermometer on the exhaust pipe. The exhaust temperature of a glycol chiller is directly proportional to the (suction and exhaust) pressure ratio and the suction temperature. The higher the suction superheat and the higher the pressure ratio, the higher the exhaust temperature, otherwise the opposite. Generally, the exhaust pressure is slightly higher than the condensing pressure.

Therefore, in order to better run the glycol chiller, users still need to understand it. If you dont understand, you can contact us at sales@cnzlh.com. LNEYA is a chiller manufacturer.
