Hermetically sealed compressors have very long life, the companies offer warranty period of up to seven years for these compressors. The suction and discharge connections and the electrical connections are available externally. The installation of the hermetically sealed compressor is very easy. The lubrication system of the hermetically sealed compressor is inherent and no external lubrication is required, unless the fresh gas charging is done.

Since no coupling, belt or pulley is involved, the maintenance is lesser. The whole condenser unit of the refrigeration or the air conditioning unit comprising of the condenser and the compressor can be moved easily from one place to the other. One does not have to disassemble the compressor from the motor and no coupling, belt and pulley arrangement is involved. The hermetically compressors can be moved easily from one place to the other place, they are highly portable. The hermetically sealed compressors are used widely in the refrigeration and air conditioning applications because of several advantages, here are some of them: Advantages of the Hermetically Sealed Compressors The centrifugal types of hermetically sealed compressor are used for the large units. This is because the rotary compressors has less frictional parts and have only a rotor. It is considered that the rotary type of hermetically sealed compressor consumes less electricity, makes lesser noise, requires lesser maintenance, and is cheaper than the reciprocating type of hermetically sealed compressor. These days the vane type of rotary compressor has become more popular. They were the first to be used as the hermetically sealed compressors are still being used widely. One of the most popular types of the hermetically sealed compressors are the reciprocating compressors. In the other image various parts of hermetically sealed multi-cylinder reciprocating compressor are shown. Such condenser units are called as hermetic condenser units. The typical condenser unit with the hermetically sealed compressor is shown in above fig. There is also socket for the electrical connection.

Additionally, the cool suction refrigerant also offers cooling effect.Įxternally, the casing has refrigerant suction and discharge connections that are connected to the evaporator and condenser respectively. The lubricant also acts the coolant for the piston and cylinder. The hermetically sealed compressors have inbuilt lubrication system for the lubrication of the piston and cylinder and crankshaft. In some cases the two halves of the shell can be bolted together instead of welding, which permits easy opening of the casing in case of compressor burnout. The steel shell comprises of two half rounded steel bodies that are welded together to form the casing for the hermetically sealed compressor. The rotating shaft of the motor extends beyond the motor and forms the crankshaft of the hermetically sealed reciprocating compressor.Īll these parts of the hermetically sealed compressor are assembled and enclosed in a strong and rigid casing made up of welded steel shell. In hermetically sealed compressors the crankshaft of the reciprocating compressor and the rotating shaft of the motor are common. This motor can be single speed or multi-speed motor. On the other side of the casing is the electric winding inside which the shaft of the motor rotates. If it is a multi-cylinder compressor, there are more than two cylinders inside the casing. In hermetically sealed compressor, in one side of the enclosed casing the various parts of the compressor like cylinder, piston, connecting rod and the crankshaft are located. Hermetically Sealed CompressorĬonstruction of the Hermetically Sealed Reciprocating Compressor The hermetically sealed compressor is very different from the traditional open type of compressors in which the compressor and the motor are different entities and the compressor is connected to the motor by coupling or belt.

This makes the whole compressor and the motor a single compact and portable unit that can be handled easily.

In hermetically sealed compressor, the compressor and the motor are enclosed in the welded steel casing and the two are connected by a common shaft. They are used with motor power requirements from 1/20 to 71/2 hp. The hermetically sealed reciprocating compressor is very easy to handle, and requires low maintenance. In all the household refrigerators, deep freezers, window air conditioners, split air conditioners, most of the packaged air conditioners, the hermetically sealed reciprocating compressor is used. The hermetically sealed reciprocating compressor is widely used for the refrigeration and air conditioning applications. Hermetically Sealed Refrigeration Compressors
