Patent number: 6557771Abstract: A controller for a climate control system has a humidity temperature sensor as well as a dry-bulb temperature sensor. A humidity temperature value is used in connection with a dry-bulb temperature value to generate an error signal that is a function of either the dry-bulb or the humidity temperature values. This permits control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. The humidity temperature can synthesized from the relative humidity and dry-bulb temperature within the enclosure.Type: GrantFiled: December 21, 2000Date of Patent: May 6, 2003Assignee: Honeywell International Inc.Inventor: Dipak J.

Publication number: 20030019359Abstract: A robust, relatively simple air quality control system that can control the air quality in buildings during both the heating and cooling seasons. In one illustrative embodiment, a first air stream is directed through an air treatment module and back into the inside space. A desiccant in the air treatment module adsorbs water, volatile organic compounds and/or particulate material from the first air stream. A second air stream is then directed through the air treatment module to a location outside of the inside space. The second air stream is preferably heated relative to the first air stream so that at least a portion of the adsorbed water, volatile organic compounds and/or particulate material are desorbed from the desiccant into the second air stream. The second air stream carries the desorbed water, volatile organic compounds and/or particulate material to a location outside the inside space.Type: ApplicationFiled: June 5, 2002Publication date: January 30, 2003Inventors: Dipak J. Shah, Chin-Hsiung Chang, John D. Howard, Ronald P. Rohrbach, Peter D. Unger, Stephen F. Yates, Brian C. Krafthefer, Russell W. Johnson

Patent number: 6012296Abstract: A controller for climate controller system having a humidity and temperature sensor wherein the controller operates to insure that both temperature and humidity are within comfort levels. Wherein said controller further controls a reheat system which reheats chilled air in order to keep the dry bulb temperature of an enclosure near a specific set point.Type: GrantFiled: August 28, 1997Date of Patent: January 11, 2000Assignee: Honeywell Inc.Inventor: Dipak J.

Patent number: 5737934Abstract: A controller for a climate control system has a relative humidity sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity value is used in conjunction with the dry-bulb temperature to generate an apparent temperature error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust control of both enclosure temperature and enclosure moisture content without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the apparent temperature, the apparent temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point apparent temperature values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.Type: GrantFiled: June 12, 1996Date of Patent: April 14, 1998Assignee: Honeywell Inc.Inventor: Dipak J.

The humidity value is used in conjunction with the dry-bulb temperature to generate an enthalpy error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the enthalpy, the enthalpy can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point enthalpy values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.Type: GrantFiled: March 1, 1996Date of Patent: October 14, 1997Assignee: Honeywell Inc.Inventor: Dipak J.

Patent number: 5555927Abstract: An adaptive recovery method for a setback thermostat using the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the temperature recovery line. The update of the temperature recovery line slope is based on miss time, i.e.Type: GrantFiled: June 7, 1995Date of Patent: September 17, 1996Assignee: Honeywell Inc.Inventor: Dipak J. Shah
