Abstract:
1. A refrigeration circuit for use in an HVAC system comprising: a cooling circuit having a high-pressure side and a low-pressure side, the cooling circuit comprising a compressor, a condenser and an evaporator, the cooling circuit capable of circulating refrigerant, a reheat circuit comprising a reheat coil, the reheat circuit in selective fluid communication with the cooling circuit, a first means for controlling flow of refrigerant, the first means selectively providing flow of refrigerant from the compressor to the reheat circuit or the cooling circuit, and a second means for controlling flow of refrigerant, the second means selectively providing flow of refrigerant from the reheat circuit to the cooling circuit, wherein the second means provides flow of refrigerant from the reheat circuit to the high-pressure side of the cooling circuit when the first means provides flow to the reheat circuit, and the second means providing flow of refrigerant from the reheat circuit to the low-pressure-side of the cooling circuit when the first means does not provide flow to the reheat circuit.
