choosing the right refrigeration for your appliction
  • 1, hermetic refrigerationcompressor

    The merit of a hermeticrefrigeration compressor is the sealing system operates under the surroundedenvelope which is not attached to the state of one or several joints.

    But this system has got someimperfections that the cooling of the motor runs under the refrigerant fluidbathing the inside of the casing which heats the fluid and is detrimental tothe refrigeration cycle. Overall, the cooling capacity is fixed, except byvarying the frequency of the supply current.

    So, if you are looking forlow and medium power capacity then go for Hermetic refrigeration compressor.Here are some brands I think are good for hermetic refrigerationcompressor.

    Sanyo Compressoradopts a stable and reliable industrial control and control system to selectthe test manually or automatically. It can execute a certain sub-test itemarbitrarily during manual test. It can automatically collect and process testdata, automatically generate test reports, and implement tests Automaticadjustment and control in the process. In the exhaust pipe game, the operatorcan immediately press the emergency stop button and make corresponding adjustments.Overall, it is quite good.

    Toshiba compressor is the world's best-selling high-tech compressors. They areideal for home cooling and small business applications. They are small, low innoise and low in vibration, achieving the highest efficiency of their kind onthe market.

    2. open refrigeration compressor

    The motor and the compressor in an open refrigerationcompressor are separated. The compressor drive shaft is attached to the motorby a coupling sleeve or by a belt and pulleys. As such you can use differenttypes of motors (electric, diesel, gas, etc.) according to your needs. Theserefrigeration compressors are therefore not known for being compact, they aremainly used for high power.

    Another merit is that all parts of the compressorare accessible for repair, unlike hermetic refrigeration compressors.

    The main disadvantage of this type ofrefrigeration compressor is the presence of a rotating seal on the compressorshaft which can become a source of refrigerant leakage with wear.

    3. Semi-hermetic refrigeration compressor:

    Still not sure about the other two just mentionabove? Then Semi-hermetic refrigeration compressors might be your type.

    As in a hermetic refrigeration compressor, themotor and compressor part are surrounded in a hermetic envelope, but thisenvelope is not attached, and all parts can be for repaired if broken.

    The motor can be cooled by the refrigerant. Thesealing system is therefore better than on an open refrigeration compressor asthere is no rotating seal on the transmission shaft. There are still staticseals on the removable parts however and the sealing is therefore not ascomplete as on a hermetic refrigeration compressor.

    Semi-hermetic refrigeration compressors are suitablefor medium power requirements, and because they offer the merit of being repairable,so they are more expensive than hermetic refrigeration compressors.
