Abstract
A compressor of a heating, ventilation, and air conditioning (HVAC) system includes a casing having an inner volume and an inner surface defining the inner volume, where the inner volume is configured to accommodate a rotor therein. The compressor also includes an economizer port formed in the casing and configured to inject a flow of fluid into the inner volume and a valve disposed within the economizer port and configured to regulate the flow of fluid into the inner volume. The valve has an inward-facing surface, and the inward-facing surface is aligned with the inner surface of the casing in a closed position of the valve.
Claims20
A compressor of a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a casing comprising an inner volume and an inner surface defining the inner volume, wherein the inner volume is configured to accommodate a rotor therein;
- an economizer port formed in the casing and configured to direct a flow of fluid into the inner volume;
- and
- a valve disposed within the economizer port and configured to regulate the flow of fluid into the inner volume, wherein the valve comprises an inward-facing surface, and wherein the inward-facing surface is aligned with the inner surface of the casing in a closed position of the valve.
A compressor of a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a casing comprising an inner volume and an inner surface defining the inner volume, wherein the inner volume is configured to accommodate a rotor therein;
- an economizer port formed in the casing and defining a bore configured to direct a flow of fluid into the inner volume;
- and
- a valve disposed within the economizer port and configured to regulate the flow of fluid into the inner volume, wherein the valve is configured to enable fluid communication between the bore and the inner volume in an open position and block fluid communication between the bore and the inner volume in a closed position.
A compressor of a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a housing comprising an inner volume and an inner surface defining the inner volume, wherein the inner volume is configured to accommodate a rotor therein;
- an economizer port formed in the housing and configured to direct vapor refrigerant from an economizer of the HVAC system into the inner volume;
- and
- a valve disposed within the economizer port and configured to regulate a flow of vapor refrigerant into the inner volume, wherein the valve comprises a main body having a radially inward surface, wherein the radially inward surface is substantially flush with the inner surface of the housing in a closed position of the valve.
