Patent number: 11480373Abstract: A chiller system includes a compressor, a condenser and an evaporator in fluid communication. A motor drives the compressor. A variable speed drive powers the motor. An oil heater and pump system circulate heated lubricating oil in the compressor. A control panel is arranged to determine whether an input parameter is greater than or equal to a threshold parameter; deactivate the VSD in response to sensing that the input parameter is less than the threshold parameter; determine at least one chiller capacity control parameter at a point when the VSD is deactivated, and maintain the at least one chiller capacity control parameter while the VSD is deactivated; determine that the input parameter has been restored; determine a motor rotation and motor rotational speed; and in response to determining that the input parameter is restored and the motor is rotating in a forward direction, reactivate the VSD.Type: GrantFiled: July 1, 2019Date of Patent: October 25, 2022Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Curtis Christian Crane, Mark Bodell, II, Curtis G. Rager, John C. Hansen, Dean K. Norbeck

Patent number: 8820105Abstract: A medium voltage power controller box is mounted on a chiller unit with the other components of the chiller system. The power controller box can be positioned on the chiller system unit to permit the power controller box to be close coupled to the motor, and specifically to the main motor lead exit hub without the need for any power conduit connections between the power controller box and the motor. In addition, the power controller box also does not require any control interface and receives controls from a control panel. A short conduit connection between the control panel and the power controller box is used to provide the necessary connections between the control panel and the power controller box.Type: GrantFiled: November 22, 2013Date of Patent: September 2, 2014Assignee: Johnson Controls Technology CompanyInventors: Dean K. Norbeck, John C. Hansen

Patent number: 7640767Abstract: The present invention is directed to a power transformer and VSD mounted on the chiller equipment. The transformer is preferably a liquid-filled transformer rated for medium/high voltage input, and at least two output low voltages, one voltage for the VSD and other power equipment, and another voltage for the control panel and control equipment. The placement of the power transformer on the chiller eliminates the need to allocate additional floor space for an auxiliary transformer or medium/high voltage VSD. The transformer also includes cooling means in the form of a heat exchanger in which the liquid is cooled by circulating condenser water, chilled water or refrigerant from the chiller system. The cooling means may also be connected to cooling coils connected to the VSD.Type: GrantFiled: June 8, 2006Date of Patent: January 5, 2010Assignee: Johnson Controls Technology CompanyInventors: Harold R. Schnetzka, Dean K. Norbeck

Patent number: 7424345Abstract: A method for repairing an HVAC system is disclosed. The method includes monitoring a plurality of sensors positioned throughout the HVAC system and receiving data associated therewith, determining whether the data received from the plurality of sensors is within corresponding predetermined operational parameters, analyzing data determined to be outside the corresponding predetermined operational parameters to diagnose a malfunction of the HVAC system, accessing an on-board bill of materials to determine a proper replacement part to correct the malfunction, automatically ordering the replacement part, and automatically dispatching a service technician to install the replacement part.Type: GrantFiled: October 15, 2007Date of Patent: September 9, 2008Assignee: York International CorporationInventor: Dean K.

Patent number: 6744061Abstract: A probe is used to detect axial movement of a rotating part such as a shaft. The probe includes a probe tube portion that protrudes into an annular groove on the rotating part. When the rotating part moves axially, one or the other side surfaces of the groove contacts the probe tube. This contact leads to a changed state of the probe, that is sensed by a sensor.Type: GrantFiled: February 20, 2003Date of Patent: June 1, 2004Assignee: York International CorporationInventors: Mark A.
