Abstract
Exemplary embodiments are disclosed of a heating, ventilation and air conditioning (HVAC) system that includes a switched mode power supply. The switched mode power supply is configured to provide standby power to the HVAC system. The standby power may be limited substantially in accordance with power demand by one or more components of the HVAC system.
Claims20
A heating, ventilation, and air conditioning (HVAC) system comprising a switched mode power supply configured to provide standby power to the HVAC system, the standby power limited substantially in accordance with power demand by one or more components of the HVAC system.
A control for a heating, ventilation, and air conditioning (HVAC) system, the control comprising a switched mode power supply configured to provide standby and operating power to the HVAC system substantially in accordance with feedback indicating power consumption by one or more low-voltage components of the HVAC system.
A method of controlling one or more low-voltage components of a heating, ventilation, and air conditioning (HVAC) system, the method performed by a control of the HVAC system, the method comprising:
- changing a line voltage input of the HVAC system to a low voltage;
- regulating the low voltage in accordance with feedback indicating power demand by one or more low-voltage components of the HVAC system;
- and
- using the regulated voltage to provide power to the one or more low-voltage components;
- wherein at least the changing and regulating are performed by a switched mode power supply of the control.
