The influence of the evaporator of the semiconductor thermostat on the refrigeration effect

Different models of semiconductor thermostat equipment have different options for evaporation.

According to different models, the choice of evaporator is different. For example, box-type semiconductor thermostat equipment uses water tank coil type evaporator; open semiconductor thermostat equipment and screw type semiconductor thermostat equipment use shell-and-tube evaporator ; For acid and alkali resistant semiconductor thermostat equipment, titanium tube evaporator or stainless steel plate exchanger can be selected. A kind of ice water machine, there are many choices, of course, can also be customized according to user needs.

The factors affecting the evaporation temperature of industrial semiconductor thermostat equipment are as follows:

There is oil in the evaporator pipeline. Under normal circumstances, because the lubricating oil and the refrigerant are mutually soluble, no oil film will be formed on the surface of the heat exchanger. The thermal resistance of the oil film may not be considered, but in the case of additional lubricating oil, the same label as the original one must be selected Lubricating oil to prevent the production of oil film.

The air filter is blocked, and the filter must be replaced regularly to ensure the circulating air volume required by the air conditioner. Dry filter clogged: In order to ensure the normal circulation of the refrigerating agent, the refrigeration system must be kept clean and dry. If the system has impurities, the dryer filter will be clogged and the system will be difficult to supply liquid, which will affect the cooling effect. Too little refrigerant, add refrigerant.

The temperature condition of the evaporator of the semiconductor constant temperature equipment. Under normal circumstances, the outer surface of the evaporator is very cold, and the condensed water drops continuously. The temperature of the inlet and outlet air is large. In abnormal conditions, the surface of the evaporator is not too cold and there is not much dew. , Or without condensation, the sound of refrigerant flowing is very loud, and the temperature difference between the inlet and outlet air is small. The reason is that the amount of refrigerant is insufficient, or the opening degree of the expansion valve is small.

The heat exchanger quality requirements of semiconductor thermostat equipment are very high. When choosing, users can also look at the quality and brand of their heat exchangers. It is recommended to choose a better one.
