1. A control system for operating a heating, ventilation, and air conditioning (HVAC) system, the control system comprising:
a control assembly configured to operationally connect to a compressor assembly of an HVAC system, wherein the control assembly is configured to operate the HVAC system in at least a first operational state to meet a first demand on the HVAC system; wherein the control assembly comprises a controller configured to control operation of a first compressor unit and a second compressor unit of the compressor assembly; wherein the first compressor unit and the second compressor unit operate in tandem to pump a first heat transfer media through the HVAC system, and wherein the first compressor unit and the second compressor unit operate at a first capacity to maintain the HVAC system in the first operational state; wherein the HVAC system comprises first flow lines for the flow of the first heat transfer media through a condenser between the compressor assembly and an expansion device, and wherein the first flow lines comprise a high pressure side of the HVAC system; wherein the controller is configured to control operation of a first fluid moving device, wherein the first fluid moving device is configured to pass a second heat transfer media over coils of the condenser of the HVAC system to transfer heat from the first heat transfer media flowing through the coils of the condenser, and wherein the first fluid moving device comprises a first speed setting configured to maintain the HVAC system in the first operational state; and wherein the controller is configured to detect a high pressure condition in the high pressure side, and, in response to detection of a high pressure condition the controller operates the HVAC system in at least one restart cycle, wherein a restart cycle comprises at least a first adjustment of an operating condition of the HVAC system, and wherein the first adjustment is selected from the following:
increasing the speed of the first fluid moving device from the first speed setting to a second speed setting, wherein the second speed setting is configured to adjust heat transfer to the high pressure side of the HVAC system to lower the pressure of the first heat transfer media in the first flow lines, andoperating the HVAC system with the first compressor on and the second compressor off. |
