Abstract
Systems and methods for controlling a cooling circuit for a variable frequency drive (VFD) in an HVACR system are disclosed. The method includes determining, by a controller, an operating condition of a heat sink associated with the VFD. The controller determines whether a temperature of the heat sink is greater than or equal to a heat sink temperature threshold. The method further includes enabling a bypass flow control device in response to the heat sink temperature being greater than or equal to the heat sink temperature threshold.
