Abstract: A heating, ventilating, and air conditioning (HVAC) system that includes a fan. The fan includes a plurality of blades coupled to a hub. A shroud is coupled to the plurality of blades, wherein the shroud focuses a flow of air along a rotational axis of the fan and reduces the flow of the air radially outward from the fan.

Abstract: A vapor compression system that includes a baffle that separates a first condenser and a first fan from a second condenser and a second fan. A controller that switches between first and second modes of operation. In the first mode of operation the controller closes a valve to block a flow of a refrigerant through a first condenser and turns off the first fan. In the second mode of operation the controller opens the valve to enable the flow of the refrigerant through the first condenser and turns on the first fan.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system. The system includes a housing with HVAC equipment. A sensor detects an operating condition of the HVAC system and wirelessly transmits a signal indicative of the operating condition. The sensor couples to or is disposed within the housing. A controller receives the signal indicative of the operating condition and controls operation of the HVAC system in response to the signal. The controller is coupled to or disposed within the housing.
