ACCOMMODATING CSSH FOR TANDEM COMPRESSOR TRANSITIONS

摘要

A heating, ventilation, and air-conditioning (HVAC) system comprises a plurality of sensors, a tandem compressor comprising a first compressor and a second compressor, and a controller communicatively coupled to the plurality of sensors and the tandem compressor. The controller is operable to operate threshold logic that turns off the tandem compressor if the tandem compressor is operating outside of a threshold range. The controller is further operable to determine a temperature demand of a structure associated with the HVAC system based on data received from at least one of the plurality of sensors and determine that the HVAC system requires a change of state to meet the temperature demand. The controller may disable the threshold logic for a pre-determined period of time in response to determining that the HVAC system requires the change of state and perform the change of state independently of the threshold logic.

1. A heating, ventilation, and air-conditioning (HVAC) system, comprising:
a plurality of sensors; a tandem compressor comprising a first compressor and a second compressor; a controller communicatively coupled to the plurality of sensors and the tandem compressor, the controller operable to:
operate threshold logic that turns off the tandem compressor if the tandem compressor is operating outside of a threshold range;determine a temperature demand of a structure associated with the HVAC system based on data received from at least one of the plurality of sensors;determine that the HVAC system requires a change of state to meet the temperature demand;disable the threshold logic for a pre-determined period of time in response to determining that the HVAC system requires the change of state; andperform the change of state independently of the threshold logic, wherein performing the change of state comprises one or more of: turning the first compressor on or off, turning the second compressor on or off, and changing the speed of an indoor blower.
