Abstract
A desuperheater of a heating, ventilation, and/or air conditioning (HVAC) system includes a first conduit defining a first fluid flow path configured to receive a refrigerant, and a second conduit defining a second fluid flow path and configured to facilitate heat transfer between the first fluid flow path and the second fluid flow path. The desuperheater also includes an inlet of the second conduit configured to receive collected water into the second fluid flow path. The desuperheater also includes a ventilation hole disposed in the second conduit and configured to vent water vapor from the second fluid flow path.
Claims29
A desuperheater of a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a first conduit defining a first fluid flow path configured to receive a refrigerant;
- a second conduit defining a second fluid flow path and configured to facilitate heat transfer between the first fluid flow path and the second fluid flow path;
- an inlet of the second conduit configured to receive collected water into the second fluid flow path;
- and
- a ventilation hole disposed in the second conduit and configured to vent water vapor from the second fluid flow path.
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a collected water source;
- a discharge line through which a refrigerant flows;
- and
- a casing surrounding a portion of the discharge line and defining a second fluid flow path between the casing and the portion of the discharge line, wherein the casing includes an inlet coupled to the collected water source and configured to receive collected water from the collected water source into the second fluid flow path to enable the collected water to cool the refrigerant in the discharge line, and wherein the casing includes ventilation holes configured to vent water vapor from the second fluid flow path.
A desuperheater of a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
- a conduit defining a first fluid flow path configured to receive a refrigerant;
- a casing surrounding the conduit and defining a second fluid flow path between the casing and the conduit, wherein the casing includes an inlet configured to receive condensate water, rain water, or both into the second fluid flow path;
- and
- a plate disposed adjacent the inlet of the second fluid flow path and configured to enable, in response to thermal expansion of the plate, a flow of the condensate water, the rain water, or both through the inlet and into the second fluid flow path.
