Abstract
A heating, ventilation, and air conditioning (“HVAC”) system includes an evaporator coil and a compressor fluidly coupled to the evaporator coil via a suction line. A condenser coil is fluidly coupled to the compressor via a discharge line and fluidly coupled to a metering device via a liquid line. A charge compensator is fluidly coupled to the liquid line via a connection line. A charge compensator re-heat valve is disposed in the connection line.

A heating, ventilation, and air conditioning (“HVAC”) system comprising:
- an evaporator coil;
- a compressor fluidly coupled to the evaporator coil via a suction line;
- a condenser coil fluidly coupled to the compressor via a discharge line and fluidly coupled to a metering device via a liquid line, wherein the metering device comprises at least one of a thermostatic expansion valve and a throttling valve;
- a charge compensator fluidly coupled to the liquid line via a connection line, wherein the charge compensator is a stand-alone device;
- wherein the connection line comprises a first end and a second end;
- wherein the first end is coupled to the liquid line and the second end is coupled to the charge compensator;
- a charge compensator re-heat valve disposed in the connection line;
- and
- a check valve arranged in the connection line in parallel with the charge compensator re-heat valve.
A condenser coil, comprising:
- a plurality of micro channels;
- a liquid line coupled to the plurality of micro channels;
- a charge compensator fluidly coupled to the liquid line via a connection line, wherein the charge compensator is a stand-alone device;
- wherein the connection line comprises a first end and a second end;
- wherein the first end is coupled to the liquid line and the second end is coupled to the charge compensator;
- a charge compensator re-heat valve disposed in the connection line;
- and
- a check valve arranged in the connection line in parallel with the charge compensator re-heat valve.
A method for operating a charge compensator, the method comprising:
- fluidly coupling a charge compensator to a liquid line via a connection line, the liquid line being fluidly coupled to a condenser coil, wherein the charge compensator is a stand-alone device;
- wherein the connection line comprises a first end and a second end;
- wherein the first end is coupled to the liquid line and the second end is coupled to the charge compensator;
- arranging a charge compensator re-heat valve in the connection line;
- arranging a check valve in the connection line in parallel with the charge compensator re-heat valve;
- operating the HVAC system in at least one of a re-heat mode and a cooling mode;
- and
- signaling, via an HVAC controller, the charge compensator re-heat valve to move to a closed position responsive to the HVAC system operating in the re-heat mode.
