    Abstract: A method for operating an air-conditioning system that carries out an air quality testing cycle is disclosed. The air quality testing cycle includes: Step A: testing if the current pollutant concentration is below a predetermined first pollutant limit value; Step B: in the event that it is determined in the Step A that the current pollutant concentration is below the first pollutant limit value, testing if the bypass device is completely open or if the current flow rate of the blower device corresponds to a current air volume demand of the air-conditioning system; Step D: in the event that it is determined in the Step B that the bypass device is not completely opened or that the current flow rate does not correspond to the current air volume demand, testing current pollutant concentration is below a predetermined second pollutant limit value that is smaller than the first pollutant limit value.

    Abstract: The present disclosure proposes a method for when the Heating, Ventilation, and Air Conditioning (HVAC) is called for by a thermostat, the GeoFlo HVAC System first exhausts a heat sink in the basement, before calling for an evaporator to be activated. When the heat sink in the basement is cooling the conditioned space, by geothermally dispersing heat into the earth, the GeoFlo HVAC turns off the evaporator. Alternatively, the system acts as a substitute for an AC evaporator. Variations of the GeoFlo HVAC system and a control box designed to move heat from one area of a building to another using the existing HVAC system are also disclosed.

    Abstract: An HVAC system that includes an air handling unit (AHU), indoor air quality (IAQ) sensors installed in one or more zones within an indoor environment, and a control device. The control device controls the IAQ sensors to measure a first set of IAQ values when air circulation to the one or more zones is turned off and controls the IAQ sensors to measure a second set of IAQ values when the air circulation to the one or more zones is turned on. The control device further compares the first set of measured IAQ values with the second set of measured IAQ values and detects at least one contaminated duct based on a result of the comparison. The control device further notifies, on a display screen or on a GUI of an application using a communication interface, a message indicating the at least one contaminated duct to a user.
