Description

Exhaust assembly, compressor and refrigeration plant

Technical Field

Background

A compressor is used in a refrigeration apparatus such as a refrigerator. With the increasingly obvious requirements of people on low noise, silence and the like of household appliances, the requirement on the noise of the compressor during working is lower and lower. In refrigeration equipment, a compressor is typically used to draw a refrigerant fluid and compress it to produce a high pressure stream of refrigerant fluid. During operation of the compressor, sound waves are often generated in the fluid and are introduced into the discharge structure of the compressor, whereby these sound waves (also called "pulsations") create noise problems.

It is currently common to use a muffler packet in conjunction with the high pressure chamber of the compressor to muffle sound through the muffler packet. The current amortization package is generally sealed two half tube-shape shells of fixing on both sides of orifice plate to form the cavity tube-shape shell, and weld the connecting pipe respectively at the both ends of cavity tube-shape shell. The compressor generally includes a crankcase and a cylinder head covering the crankcase. A buffer chamber is generally provided in the cylinder head, and high-pressure refrigerant in the crankcase is introduced into the buffer chamber to be silenced by the buffer chamber. In order to improve the silencing effect, a silencing bag is often connected. Since the muffler bag is disposed on the exhaust side of the high pressure, the connection of the muffler bag to the buffer chamber needs to be well sealed. It is currently common to use a connecting tube to connect the buffer chamber to the sound-damping bag to facilitate a sealed connection between the sound-damping bag and the buffer chamber by virtue of the smaller diameter of the connecting tube.
