摘要： A method for operating a heating, ventilation, and air condition (“HVAC”) system includes determining a current temperature of the enclosed space and receiving a first comfort temperature. The method further including determining, based on a selection of a time period, a first consumption value indicating a predicted amount of energy required to maintain the first comfort temperature for the time period, wherein the first consumption value is determined based at least on a first predicted value and a second predicted value, the first predicted value being indicative of an amount of energy required to condition the enclosed space to the first comfort temperature from the current temperature and the second predicted value being indicative of an amount of energy required to, upon conditioning the enclosed space to the first comfort temperature, maintain the first comfort temperature for the time period.

摘要： A method includes initiating, by a controller of a heating, ventilation, and air conditioning (“HVAC”) system, a filter calibration procedure, curve fitting a first line based on a plurality of static pressure measurements and corresponding flowrates of air, and generating a second line based on the first line. The method further includes determining a first static pressure measurement sensed by at least one sensor in response to determining that a first flowrate of air has been moved by the at least one blower and comparing the first static pressure value to a predicted static pressure value of the second line, the predicted static pressure value corresponding to the first flowrate of air. The method further includes determining that an air filter of the HVAC system has no more usable life in response to determining that the first static pressure value is greater than the predicted static pressure value.

摘要： A system comprising an air conditioning unit operable to run at a capacity level determined by a difference between a temperature set-point and an actual temperature of an environment. The system comprises a humidity sensor, a temperature sensor, and a controller. The controller comprises a memory and a microprocessor. The controller is operable to operate the air conditioning unit in a normal mode and a tracking mode comprising operating the air conditioning unit at a reduced capacity comprising setting the temperature set-point of the air conditioning unit as a tracked actual temperature of the environment. The controller is operable to terminate the tracking mode if the actual temperature of the environment either rises above the first temperature value or drops below the second temperature value, or if the humidity level of the environment drops below the humidity threshold.

摘要： According to some embodiments, a heating, ventilating and air conditioning (HVAC) system comprises a circulation fan, one or more humidity sensors operable to sense humidity data associated with an enclosed space, and a controller. In operation, the controller receives the humidity data from the one or more humidity sensors and receives air quality data associated with at least one air pollutant. The controller determines, based on the air quality data, that a threshold associated with the air pollutant has been exceeded and determines, based on the humidity data, that a threshold associated with humidity has not been exceeded. The controller operates the circulation fan in response to determining that the threshold associated with the air pollutant has been exceeded and the threshold associated with humidity has not been exceeded, the circulation fan operated for filtration purposes while not servicing any conditioning demand.

摘要： In some embodiments, a controller for a heating, ventilating and air conditioning (HVAC) system comprises an interface and a processor. The interface receives a comfort temperature set point and a sensed temperature for the enclosed space. The comfort temperature set point comprises a single set point used for both heating and cooling mode operation of the HVAC system. The processor determines a total error value based on comparing the sensed temperature and comfort temperature set point, selects a mode of operation based on the total error value, and operates the HVAC system in the selected mode of operation.
