Abstract: In various implementations, an ice sensor may include heater(s), ice accumulation surface(s), and/or temperature sensor(s). During operation, heat from a heater may be provided to an ice accumulation surface and a temperature sensor(s) may determine temperature(s) of the ice accumulation surface. A determination of whether ice is present on the ice sensor may be based at least partially on the determined temperature(s).

Abstract: 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.

Abstract: In one aspect, the present disclosure provides a controller for a HVAC system having an economizer with a damper and pressure sensors on opposing sides of the economizer. The controller comprise a diagnostics controller having a program configured to use pressure difference sensor data to determine if a pressure difference across the economizer is outside an operational design parameter of the HVAC system, and generate an error signal when the pressure difference is outside the operational design parameter.

Abstract: Systems and methods are disclosed for ventilating a building using a rooftop heating ventilating and air conditioning system that in one instance involve determining a first outdoor airflow into the system through a barometric relief damper; subtracting the first outdoor airflow from a minimum required outdoor airflow rate to arrive at second outdoor airflow; and setting an outdoor damper to provide an outdoor airflow through the outdoor damper that is greater than or substantially equal to the second outdoor airflow. Other systems and methods are disclosed.

Abstract: Systems and methods are disclosed for detecting a refrigerant charge in a cooling system. The systems and methods involve performing at least a partial pump down of the refrigerant while monitoring one or more metrics. The measured metrics may be compared to a standard in order to determine if a refrigerant leak has occurred or to determine other refrigerant information. Other systems and methods are disclosed.
