US Patent:

20190390865, Dec 26, 2019
Filed:

Jun 22, 2018
Appl. No.:

16/015475
Inventors:

- Davidson NC, US
Darryl E. Denton - Tyler TX, US
Assignee:

Trane International Inc. - Davidson NC
International Classification:

F24F 11/46
G05B 15/02
F24F 3/044
F24F 11/58
F24F 11/64
F24F 11/65
F24F 11/72
F24F 13/10
Abstract:

Configuration of flow paths for the output (e.g., chilled or heated air) of an HVAC system is described. In one embodiment, a demand response message can be received from a resource provider requesting that the HVAC system increase or decrease consumption of the resource. If the request is satisfied, then the output from the HVAC device will be increased or decreased resulting in potential discomfort for occupants. This output, however, rather than being distributed in a uniform manner, can instead be distributed, via ventilation elements of the HVAC system in a non-uniform way according to the flow paths. The flow paths can be determined to direct sufficient output to high priority zones in order to, e.g., satisfy a comfort level in the high priority zones.

US Patent:

20160370023, Dec 22, 2016
Filed:

Jun 20, 2016
Appl. No.:

15/186715
Inventors:

- Davidson NC, US
Karl J. Mutchnik - Tyler TX, US
Carl L. Garrett - Tyler TX, US
Darryl E. Denton - Tyler TX, US
Assignee:

Trane International Inc. - Davidson NC
International Classification:

F24F 11/00
G06N 99/00
Abstract:

Systems and methods for fault detection and diagnosis (FDD) in a heating, ventilation and air conditioning (HVAC) system include a server identifying a fault and one or more predicted causes of the fault based on measurements of operational parameters from the HVAC system. The server also receives and utilizes information associated with the reported fault from service technicians who service the HVAC to correct the reported fault condition. The information includes details of the corrective measures successfully implemented by the technicians to correct the fault, and a determination of whether the server correctly identified the actual fault. The information is implemented by the server to improve the accuracy of the FDD algorithms based on measured parameters of the HVAC system.

Filed:

Jan 8, 2016
Appl. No.:

14/991673
Inventors:

- Piscataway NJ, US
Darryl Elliott Denton - Tyler TX, US
International Classification:

F25D 21/00
F24F 13/22
Abstract:

Systems and methods are disclosed that include providing a heating, ventilation, and/or air conditioning (HVAC) system with a controller that may adjust the defrost procedure algorithm by monitor the refrigeration coil temperature sensor and the ambient outdoor temperature sensor, calculate an Actual Coil Delta Temperature (ACDT); compare the calculated ACDT to an Initiate Delta Temperature (DTINIT) associated with the measured ambient outdoor temperature; initiate a defrost procedure in response to the calculated ACDT being greater than or equal to the DTINIT; determine if the duration of the defrost procedure is within a predetermined time threshold; and adjust the duration of a next defrost procedure in response to determining that a predetermined number of consecutive defrost procedures have occurred outside of the predetermined time threshold.

US Patent:

20160216026, Jul 28, 2016
Filed:

Jan 8, 2016
Appl. No.:

14/991565
Inventors:

- Piscataway NJ, US
Darryl Elliott Denton - Tyler TX, US
International Classification:

F25D 21/06
G01K 15/00
Abstract:

Systems and methods are disclosed that include providing a heating, ventilation, and/or air conditioning (HVAC) system with a temperature sensor validation system that measures the ambient outdoor temperature using a first temperature sensor and the refrigeration coil temperature using a second temperature sensor at a plurality of time intervals following a refrigeration coil defrost procedure. A system controller may implement an algorithm to determine if the first temperature sensor and the second temperature sensor are reliable by comparing the temperature readings from the first temperature sensor and the second temperature sensor taken at the plurality of time intervals following the defrost procedure. The system controller may also implement so-called limp along modes if any temperature sensor is determined unreliable.

Abstract:

Systems and methods are provided for operating a heating, ventilation, and/or air conditioning (HVAC) system that include recording a number of consecutive occasions in which a defrost mode is entered within a first predefined length of time after a heating cycle is entered, preventing operation of at least one component of the HVAC system for a second predefined length of time in response to entering the defrost mode a first predetermined consecutive number of occurrences within the first predefined length of time after a heating cycle is entered, recording a number of consecutive preventions of operation of the component of the HVAC system, and determining that a fault condition exists in the HVAC system in response to the number of consecutive temporary preventions of operation of the component of the HVAC system exceeding a second predefined number of occurrences.
