Effect of High Precision Semiconductor Constant Temperature Series Evaporator on Refrigeration

The high-precision semiconductor constant temperature series of different models of the equipment, the choice of evaporation is also different, then, what effect does the heat exchanger have on the high-precision semiconductor constant temperature series?

Depending on the model, the choice of evaporator is different, such as box-type high-precision semiconductor constant temperature series, using water tank coil evaporator; open high-precision semiconductor constant temperature series and screw high-precision semiconductor constant temperature series, Shell-and-tube evaporators are available; for acid-base high-precision semiconductor constant temperature series, titanium tube evaporators or stainless steel plate exchangers are available. A chiller can have a variety of options, of course, can be customized according to user needs.

The factors affecting the evaporation temperature of industrial high-precision semiconductor constant temperature series are as follows:

The evaporator pipe is oily. Under normal conditions, since the lubricating oil and the refrigerant are mutually soluble, no oil film is formed on the surface of the heat exchanger, and the oil film thermal resistance may be disregarded. However, in the case of additional lubricating oil, the same label as the original one must be used. Lubricating oil to prevent the formation of oil film.

The air filter is clogged and the filter must be replaced regularly to ensure the required circulation air volume. Dry filter plugging: In order to ensure the normal circulation of the cooling enthalpy, the refrigeration system must be kept clean and dry. If the system has impurities, the drying filter will be blocked, the system will be difficult to supply liquid, and the cooling effect will be affected. Too little refrigerant, additional refrigerant.

The temperature condition of the high-precision semiconductor constant temperature series evaporator. Under normal conditions, the outer surface of the evaporator is very cold, and the condensation water drops continuously, the temperature of the inlet and outlet air is large, abnormal, the surface of the evaporator is not too cool, dew Not much, or no condensation, you can hear the sound of the refrigerant flow is very loud, the temperature difference between the inlet and outlet is small. The reason is that the refrigerant amount is insufficient, or the expansion valve opening degree is small.

The quality requirements of high-precision semiconductor constant temperature series heat exchangers are very high. When users choose, they can also look at the quality and brand of their heat exchangers. It is recommended to choose a better one.
