Abstract
A low-volume vapor compression air conditioning system is provided. The system comprises a compressor, a condenser, low-pressure and high-pressure working fluid conduits, a pressure sensor, a temperature sensor, and a working fluid flow restrictor. The restrictor comprises a housing; a first end face and a second end face within the housing; a plug movable within a passage in communication between the first and second end faces; a seat in the housing between the plug and the second end face, wherein the seat and the plug are arranged such that, when the plug engages the seat, flow from the first end face to the end face is restricted. The restrictor is configured to control flow of working fluid in response to the measured temperature and pressure of the working fluid within the high pressure working fluid conduit.
