These style compressors just don’t seem to hold up that well compared to semi hermetic compressors. These style compressors are classified in the refrigeration field as “throw away/non repair compressors”.

These styles of compressors are built for longevity, repairable and more reliable. The life of a compressor is biased on its application, time it has been running, glycol used and so many other factors. In the refrigeration world, you can see compressors lasting either a short period of time or long. Prepared By : MOHAMMED ABDUL MUJEEB KHAN - B.TECH MECHANICAL ENGINEER BASICS OF HVACBASICS OF HVAC
Editor's Notes
- The three basic principles of heat transfer discussed in this clinic are: 1) Heat energy cannot be destroyed; it can only be transferred to another substance. To produce cooling, heat must be removed from a substance by transferring the heat to another substance. This is commonly referred to as the principle of "conservation of energy." Ice cubes are typically placed in a beverage to cool it before being served. As heat is transferred from the beverage to the ice, the temperature of the beverage is lowered. The heat removed from the beverage is not destroyed, but instead is absorbed by the ice, melting the ice from a solid to a liquid. 2) Heat energy naturally flows from a higher-temperature substance to a lower-temperature substance, in other words, from hot to cold. Heat cannot naturally flow from a cold substance to a hot substance. Consider the example of the beverage and the ice cubes. Because the temperature of the beverage is higher than the temperature of the ice cubes, heat will always flow from the beverage to the ice cubes. 3) Heat energy is transferred from one substance to another by one of three basic processes: conduction, convection, or radiation.
