There are many components in semiconductor thermostats, including the main parts such as compressors, heat exchangers, evaporators, and expansion valves. Additionally, components like the accumulator, oil-gas separator, and desiccant filter are also quite important. What are the roles of these three components in semiconductor thermostats?
The oil separator is installed between the compressor and the condenser. The compressor's exhaust is a mixture of refrigerant and lubricating oil gases, which slows down as it passes through the larger chamber of the separator. The misty oil gathers on the impact surface, and once aggregated into larger oil droplets, it flows to the bottom of the separator and is returned to the compressor via a return system.
The role of the filter in a semiconductor thermostat is to prevent moisture from entering the refrigerant or from other unavoidable elements, causing water to infiltrate the system. As the high-temperature liquid exiting the condenser enters the expansion valve, its temperature drops significantly, usually below freezing. If the system contains moisture at this point, and due to the small cross-section of the expansion valve, it is prone to ice blockages, which can affect the normal operation of the system.
The high-pressure accumulator, also known as the accumulator tank, in the refrigeration system is installed between the condenser and the expansion valve. Its functions can be summarized in several aspects: storing the condensate from the condenser to prevent excessive accumulation and reduce the heat transfer area, thereby affecting the condenser's heat transfer efficiency. When the evaporation load increases, the supply also increases, supplemented by the stored liquid in the accumulator; when the load decreases, the required liquid volume also decreases, with the excess liquid stored in the accumulator tank. Since the outlet pipe is inserted below the liquid level, it prevents steam and non-condensable gases from the high-pressure side from entering the low-pressure side. Additionally, the accumulator serves as a filter and noise reducer. Accumulators come in various types, including single-direction and bi-directional; single outlet and double outlet; and vertical and horizontal configurations.
Semiconductor thermostats are widely used in the semiconductor industry for cooling, heating, and temperature control. Performance requirements are self-evident, so it is recommended to purchase from professional manufacturers.
