HVAC unit with hot gas reheat

A heating, ventilating, or air conditioning system comprising:

• a compressor configured to compress a gaseous refrigerant to provide compressed refrigerant;
• a first condenser configured to receive and to condense a first portion of the compressed refrigerant in a first mode of system operation and a second mode of system operation to provide a first portion of condensed refrigerant;
• a second condenser configured to receive and to condense a second portion of the compressed refrigerant and to operate in parallel with the first condenser in the first mode of system operation to provide a second portion of condensed refrigerant, wherein the system is configured to bypass the second condenser with the second portion of the compressed refrigerant in the second mode of system operation;
• at least one expansion device configured to receive and to reduce pressure of the first portion of condensed refrigerant from the first condenser along with a portion of cooled refrigerant in the second mode of system operation to provide expanded refrigerant and configured to receive and reduce pressure of the first and second portions of the condensed refrigerant from the first and the second condensers in the first mode of system operation to provide the expanded refrigerant;
• an evaporator configured to evaporate the expanded refrigerant to provide evaporated refrigerant prior to returning the evaporated refrigerant to the compressor;
• a reheat heat exchanger configured to transfer heat from the second portion of the compressed refrigerant to a fluid cooled by the evaporator to condense the second portion of the compressed refrigerant to provide the portion of cooled refrigerant;
• a reheat circuit configured to direct the second portion of the compressed refrigerant from a discharge port of the compressor to the reheat heat exchanger;
• and
• a controller configured to switch the system between the first mode of system operation where the refrigerant is circulated through the compressor, the first condenser and the second condenser in parallel, the expansion device, and the evaporator and the second mode of system operation where the refrigerant is circulated through the compressor, the first condenser and the reheat heat exchanger in parallel, the expansion device, and the evaporator.
