Abstract
A control system for a climate management system configured to control climate characteristics of a building includes a memory device and a processor. The memory device includes instructions that, when executed by the processor, cause the processor to receive, via a sensor, data indicative of an evaporator coil temperature of the climate management system, and operate an air mover of the climate management system to control supply of conditioned air to the building based on the evaporator coil temperature.
Claims19
A non-transitory computer-readable medium, comprising instructions that, when executed by one or more processors, are configured to cause the one or more processors to:
- receive, via a first sensor, data indicative of an evaporator coil temperature of a heating, ventilation, and air conditioning (HVAC) system;
- receive, via a second sensor, data indicative of a humidity level in a space conditioned by the HVAC system;
- operate a blower of the HVAC system at an operating fan speed to control supply of conditioned air to the space based on the evaporator coil temperature relative to an evaporator coil set-point temperature in response to a determination that the humidity level is above a threshold level;
- and
- regulate the operating fan speed of the blower to be equal to or greater than a minimum allowable fan speed in response to a determination that the humidity level is below the threshold level.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- an evaporator coil;
- a blower configured to direct air across the evaporator coil;
- and
- a controller configured to;
- receive, via a sensor, data indicative of a humidity level within a space conditioned by the HVAC system;
- operate the blower at an operating speed to maintain a temperature of the evaporator coil at a set-point temperature of the evaporator coil in response to a determination that the humidity level within the space conditioned by the HVAC system is above a threshold level;
- and
- regulate the operating speed of the blower to be equal to or greater than a minimum allowable speed in response to a determination that the humidity level within the space conditioned by the HVAC system is below the threshold level.
A control system for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- one or more processors;
- and
- a memory comprising instructions that, when executed by the one or more processors, are configured to cause the one or more processors to:
- determine, based on data received via a first sensor, an evaporator coil temperature of the HVAC system;
- determine, based on data received via a second sensor, a humidity level in a space conditioned by the HVAC system;
- adjust an operating speed of a blower configured to supply conditioned air to the space based on the evaporator coil temperature relative to an evaporator coil set-point temperature in response to a determination that the humidity level is above a threshold value;
- and
- regulate the operating speed of the blower to be equal to or greater than a minimum allowable speed in response to a determination that the humidity level is below the threshold value.
