Abstract
An air flow monitoring system for a heating, ventilation, and air conditioning (HVAC) system includes one or more sensors configured to detect data indicative of a velocity of an air flow directed through a blower of the HVAC system, and a controller configured to regulate operation of a heating unit of the HVAC system based on the data indicative of the velocity of the air flow directed through the blower.
Claims20
An air flow monitoring system for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- one or more sensors configured to detect data indicative of a velocity of an air flow directed through a blower of the HVAC system;
- and
- a controller configured to regulate operation of a heating unit of the HVAC system based on the data indicative of the velocity of the air flow directed through the blower.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- a housing configured to receive an air flow;
- a blower assembly positioned within the housing and comprising one or more blowers, wherein the one or more blowers are configured to bias the air flow through the housing;
- a heating unit positioned within the housing and configured to transfer heat to the air flow directed through the housing;
- and
- an air flow monitoring system, comprising:
- one or more sensor assemblies positioned within the housing and configured to detect data indicative of a flow rate of the air flow biased through the housing via the one or more blowers;
- and
- a controller configured to control operation of the heating unit based on the data.
A rooftop unit for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a housing comprising a blower chamber;
- one or more blowers disposed within the blower chamber and configured to direct an air flow through the housing;
- a heating unit positioned within the housing downstream of the blower chamber, relative to a flow direction of the air flow through the housing, wherein the heating unit is configured to heat the air flow during a heating mode of the HVAC system;
- one or more sensors coupled to the one or more blowers, wherein the one or more sensors are configured to detect data indicative of a velocity of the air flow;
- and
- a controller configured to:
- compare the velocity to one or more threshold values;
- and
- adjust an amount of heat output by the heating unit based on a comparison of the velocity to the one or more threshold values.
