Abstract (en)
A heating, ventilation, and air-conditioning (HVAC) system (1000) comprises a plurality of sensors (129), a plurality of tandem compressor assemblies (101, 102) that each comprise a first compressor (112) and a second compressor (114), and a controller (126) communicatively coupled to the plurality of sensors (129) and the plurality of tandem compressor assemblies (101, 102). The controller (126) determines an increase in a cooling demand of a structure associated with the HVAC system (1000) based on data received from at least one of the plurality of sensors (129). Also, the controller (126) compares an ambient temperature outside of the structure to a first threshold. In response to determining that the ambient temperature is greater than the first threshold, the controller (126) operates the HVAC system (1000) in a first mode and in response to determining that the ambient temperature is less than the first threshold, the controller operates the HVAC system in a second mode.
