  • Publication number: 20240035724
    Abstract: A heating, ventilation, and air conditioning (HVAC) system includes an outdoor heat exchanger configured to circulate a working fluid therethrough and to place the working fluid in a heat exchange relationship with an ambient air flow, a fan configured to direct the ambient air flow across the outdoor heat exchanger, a motor configured to drive rotation of the fan, and a control system electrically coupled to the motor. The control system includes a fan controller configured to modulate a speed of the fan, and the control system is configured to selectively enable and disable electrical communication from the fan controller to the motor in response to an ambient temperature detected by the control system.

  • Publication number: 20210356152
    Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a plurality of condenser fans and a control system. The control system is configured to perform operations that include identifying an ambient condition, determining an operating mode of the HVAC system, and operating a subset of the plurality of condenser fans based on the operating mode and in response to identification of a low ambient condition.

  • Patent number: 5033548
    Abstract: An aqueous solution comprised of partially hydrolyzed polyacrylamide and an ethoxylated alcohol, is injected into a subterranean hydrocarbon bearing formation via an injection well followed by injection of a drive fluid. The solution displaces hydrocarbons from formation pores and the drive fluid pushes the displaced hydrocarbon and the aqueous solution toward a production well enhancing hydrocarbon production. The ethoxylated alcohol decreases solution viscosity and increases solution screen factors resulting in improved injectivity, improved mobility control and ultimately improved hydrocarbon production.
