Abstract:
A compressor has a suction port, a discharge port, and an economizer port. A condenser is downstream of the discharge port. An evaporator is upstream of the suction port. An expansion device is between the condenser and the evaporator. An economizer is between the condenser and the evaporator. An economizer line extends from the economizer to the economizer port. A resonator is located in the economizer line and has a first branch and a second branch. A first flowpath length across the resonator through the second branch is longer than a second flowpath length across the resonator through the first branch.
