Compressor with mufflers

Abstract

Disclosed herewith is a compressor with mufflers. The compressor comprises a drive unit, a compression unit, at least a pair of exhaust mufflers, a coolant exhaust conduit, and a connecting conduit. The drive unit generates power. The compression unit sucks, compresses and exhausts coolant using power transmitted from the drive unit. The exhaust mufflers temporarily store coolant exhausted from the compressing unit. The coolant exhaust conduit is connected to one of the exhaust mufflers to guide the exhaust of coolant to the outside. The connecting conduit connects the exhaust mufflers to each other to cancel out noises during the recombination of divided coolant in one of the exhaust mufflers.

What is claimed is:  
     
         1 . A compressor, comprising: 
 a drive unit for generating power;    a compression unit for sucking, compressing and exhausting coolant by power transmitted from said drive unit;    at least a pair of exhaust mufflers in which coolant exhausted from said compressing unit is temporarily stored;    a coolant exhaust conduit connected to one of said exhaust mufflers to guide the exhaust of coolant to the outside; and    a connecting conduit connecting said exhaust mufflers to each other to cancel out noises during the recombination of divided coolant in one of said exhaust mufflers.    
     
     
         2 . The compressor according to  claim 1 , where said connecting conduit is constructed to have a length such that a first noise in a first exhaust muffler of said exhaust mufflers is allowed to be opposite in phase to a second noise in a second exhaust muffler after being transmitted to said second exhaust muffler.  
     
     
         3 . The compressor according to  claim 1 , wherein under the conditions that the frequency bands of the noises generated in said exhaust mufflers are 350 to 600 Hz and the transmission speed of a noise in coolant is 161 m/s, said connecting conduit has a length ranging from 13.4 to 23 cm.  
     
     
         4 . A compressor, comprising: 
 a drive unit for generating power;    a compression unit for sucking, compressing and exhausting coolant utilizing power transmitted from said drive unit;    at least a pair of exhaust mufflers in which coolant exhausted from said compressing unit is temporarily stored;    a coolant exhaust conduit connected to one of said exhaust mufflers to guide the exhaust of coolant to the outside;    at least a pair of coolant passages each connecting said compression unit to each of said exhaust mufflers, said coolant passages having different lengths so that noises of coolant have opposite phases after the coolant passes through said coolant passages; and    a connecting conduit connecting said exhaust mufflers to each other to cancel out said noises having opposite phases during the recombination of divided coolant in one of said exhaust mufflers.
