    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 translation: 根据一些实施例，加热，通风和空调（HVAC）系统包括循环风扇，可操作以感测与封闭空间相关联的湿度数据的一个或多个湿度传感器和控制器。 在操作中，控制器从一个或多个湿度传感器接收湿度数据，并接收与至少一个空气污染物相关联的空气质量数据。 控制器基于空气质量数据确定已经超过与空气污染物相关联的阈值，并且基于湿度数据确定没有超过与湿度相关联的阈值。 控制器响应于确定已经超过与空气污染物相关联的阈值并且没有超过与湿度相关的阈值来操作循环风扇，循环风扇在不进行任何调节需求的情况下用于过滤目的。

    Abstract: A method for performing a pump down cycle to isolate an indoor section of a heating, ventilation, and air conditioning (HVAC) from an indoor section of the HVAC system is disclosed. The method includes transmitting a first control signal to a compressor of the HVAC system. The first control signal causes the compressor to turn on or stay turned on. The method further includes transmitting a second control signal to a vapor line isolation valve. The second control signal causes the vapor line isolation valve to open. The method further includes transmitting a third control signal to a liquid line isolation valve. The third control signal causes the liquid line isolation valve to close. The method further comprises determining that a refrigerant charge in the indoor section has become less than a threshold value. In response, the compressor is turned off and the vapor line isolation valve is closed.
