Abstract
A heating, ventilation, and/or air conditioning (HVAC) system includes a refrigerant circuit configured to circulate a refrigerant to condition an air flow within an air flow conduit and a reheat system fluidly separate from the refrigerant circuit, wherein the reheat system is configured to utilize a waste fluid from a waste heat source to reheat the air flow conditioned by the refrigerant circuit.
Claims6
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a refrigerant circuit configured to circulate a refrigerant to condition a first air flow within an air flow conduit in a reheating mode of the HVAC system;
- an evaporator of the refrigerant circuit, wherein the evaporator is configured to place the refrigerant in a first heat exchange relationship with the first air flow to cool the first air flow in the reheating mode;
- a reheat heat exchanger fluidly separate from the refrigerant circuit, wherein the reheat heat exchanger is configured to place a waste fluid in a second heat exchange relationship with the first air flow to reheat the first air flow cooled by the evaporator in the reheating mode;
- a condenser of the refrigerant circuit, wherein the condenser is configured to place the refrigerant in a third heat exchange relationship with a second air flow to cool the refrigerant in the reheating mode;
- and
- a reservoir fluidly coupled to the reheat heat exchanger and configured to store the waste fluid for supply to the reheat heat exchanger.
