A vapor compression system including: a compressor having a compressor suction port and a compressor discharge port configured to circulate a working fluid through a flow circuit; a first heat exchanger operably coupled to the compressor discharge port; a second heat exchanger operably coupled to the compressor suction port; a heat recovery heat exchanger operably coupled to the first and second heat exchangers wherein the heat recovery heat exchanger is configured to: receive the working fluid in a first phase from the first heat exchanger; receive the working fluid in a second phase from the second heat exchanger; exchange heat between the working fluid in the first phase and the second phase; and a bypass valve positioned between the heat recovery heat exchanger discharge and the second heat exchanger and defining a first flow path and a second flow path.

Vapor compression system and method for vapor oil recovery

Disclosed is a muffler for a water-cooled chiller or air-cooled of a vapor-compression or absorption refrigeration system, the muffler having: an upstream case having a fluid inlet; a downstream case connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet; the upstream case having a plurality of axially adjacent outer muffler rings and a plurality of axially adjacent inner muffler rings, the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage therebetween, wherein the outer muffler rings and inner muffler rings are a metal mesh material.

Muffler with metallic meshed rings

Disclosed is a muffler for a water-cooled chiller or air-cooled of a vapor-compression or absorption refrigeration system, the muffler having: an upstream case () having a fluid inlet (); a downstream case () connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet (); the upstream case having a plurality of axially adjacent outer muffler rings () and a plurality of axially adjacent inner muffler rings (), the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage () therebetween, wherein the outer muffler rings and inner muffler rings are a metal mesh material.

A vapor compression system () comprises: a compressor () having a suction port () and a discharge port (); a refrigerant flowpath () from the discharge port and returning to the suction port; a first heat exchanger () along the refrigerant flowpath; a second heat exchanger () along the refrigerant flowpath; and a vaporizer system (). The vaporizer system comprises: a first vaporizer (A;A) and a second vaporizer (B:B) each comprising: a vessel () having an inlet (), a vapor outlet (), and a liquid outlet (); and a gas bypass flowpath () in heat transfer relation with an interior of the vessel.

Multi-stage oil batch boiling system

A vaporizer has: an inlet (); an oil outlet (); a vent (); a hot gas inlet (); and a cooled gas outlet (). A gas flowpath () extends from the hot gas inlet to the cooled gas outlet. A vaporizer chamber () is downstream of the inlet along a primary flowpath. A gas conduit () is along the gas flowpath in heat exchange relation with the primary flowpath. A sump () is below the vaporizer chamber. A housing () encloses the sump and the vaporizer chamber. A passageway extends from the vaporizer chamber to the sump.
