Method and apparatus for re-heat circuit operation

An evaporator coil, comprising:

• a primary segment that receives refrigerant from a condenser coil and discharges refrigerant to a compressor;
• a secondary segment fluidly coupled to the compressor via a reversing valve, the secondary segment having a first fluid connection to the condenser coil via a re-heat return line and a second re-heat feed line, the secondary segment having a second fluid connection to the condenser coil via a condenser intake line, wherein the secondary segment is positioned directly above the primary segment;
• wherein, in a re-heat mode, the secondary segment receives refrigerant from the compressor and discharges refrigerant to the condenser coil via the second fluid connection;
• and
• wherein, in a cooling mode, the secondary segment receives refrigerant from the condenser coil via the second fluid connection and discharges refrigerant to the compressor.

A heating, ventilation, and air conditioning (“HVAC”) system comprising:

• a condenser coil;
• a valve fluidly coupled to the condenser coil;
• a distributor fluidly coupled to the valve;
• an evaporator coil, wherein the evaporator coil comprises:
• a primary segment fluidly coupled to the distributor via a plurality of evaporator circuit lines, wherein the primary segment receives refrigerant from the condenser coil and discharges refrigerant to a compressor;
• a secondary segment fluidly coupled to the compressor via a reversing valve, the secondary segment having a first fluid connection to the condenser coil via a re-heat return line and a second re-heat feed line, the secondary segment having a second fluid connection to the condenser coil via a condenser intake line, wherein the secondary segment is positioned directly above the primary segment;
• a first check valve disposed in the first fluid connection;
• and
• a second check valve disposed in the second fluid connection;
• and
• wherein the HVAC system operates in at least one of a cooling mode and a re-heat mode.
