Therefore, refrigeration dryers (freeze dryers) have refrigeration systems. In the refrigeration system of a refrigeration dryer, the evaporator is a device that delivers cold, where the refrigerant absorbs heat from the compressed air to achieve dehydration and drying.
Therefore, refrigeration dryers (freeze dryers) have refrigeration systems. In the refrigeration system of a refrigeration dryer, the evaporator is a device that delivers cold, where the refrigerant absorbs heat from the compressed air to achieve dehydration and drying. The compressor is the heart, responsible for inhaling, compressing, and delivering refrigerant vapor. The condenser is a device that releases heat, transferring the heat absorbed by the evaporator along with the heat converted from the compressor's input power to a cooling medium (such as water or air) to dissipate it. The expansion valve/throttle valve throttles and reduces the pressure of the refrigerant, simultaneously controlling and regulating the amount of refrigerant liquid flowing into the evaporator, and dividing the system into two major parts: high-pressure and low-pressure sides. In addition to the above components, the SSS type refrigeration dryer also includes an energy regulating valve, high and low pressure protectors, an automatic drain valve, and a control system.
