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.
Claims18
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;
- a charge compensator fluidly coupled to the liquid line via a connection line;
- a charge compensator re-heat valve disposed in the connection line;
- a check valve disposed in the connection line in parallel with the charge compensator re-heat valve;
- and
- wherein a first end of the charge compensator re-heat valve is connected to the liquid line via the connection line and a second end of the charge compensator re-heat valve is connected to the charge compensator.

A method for operating a charge compensator, the method comprising:
- fluidly coupling a charge compensator to a liquid line, the liquid line being fluidly coupled to a condenser coil;
- arranging a charge compensator re-heat valve in a connection line coupling the liquid line and the charge compensator;
- arranging a check valve in the connection line in parallel with the charge compensator re-heat valve;
- operating an HVAC system in a re-heat mode;
- signaling, via an HVAC controller, a charge compensator re-heat valve to move to a closed position responsive to the HVAC system operating in the re-heat mode;
- and
- wherein a first end of the charge compensator re-heat valve is connected to the liquid line via the connection line and a second end of the charge compensator re-heat valve is connected to the charge compensator.
