Evaporation Apparatus For High Efficiency Fire Place Or Heater With Humidification Feature

US Patent:
2013025, Oct 3, 2013
Filed:
Mar 27, 2013
Appl. No.:
13/851503
Inventors:
Bruce Dresner - St. Louis MO, US
David M. Christensen - Sioux Falls SD, US
Scott G. Schulte - St. Louis MO, US
Assignee:
EMPIRE COMFORT SYSTEMS, INC. - Belleville IL
International Classification:
F24H 8/00
US Classification:
126508
Abstract:
A heater having an evaporating and humidifying apparatus therein, the evaporating and humidifying apparatus comprising a fluid pan with a heating element. In one aspect, the pan is in fluid communication with a condensate trap assembly. In one aspect the apparatus can include a base pan, the heating element, an insulator and an evaporation pan above the heating element. The evaporating and humidifying apparatus can include a fluid level sensor operatively associated with the heater controls. The condensate trap assembly may include a fluid level sensor operatively associated with the heater controls to determine fluid levels in the trap assembly. In one aspect the pan comprises an ultrasonic vaporization element in lieu of a heating element.

Control System For Space Heater/Hearth

US Patent:
2013021, Aug 22, 2013
Filed:
Feb 19, 2013
Appl. No.:
13/770446
Inventors:
Bruce Dresner - St. Louis MO, US
Frank D. Wurth - Mascoutah IL, US
David M. Christensen - Sioux Falls SD, US
Assignee:
Empire Comfort Systems, Inc. - Belleville IL
International Classification:
F23N 1/02
US Classification:
431 6, 431 12, 431 89
Abstract:
A fuel burning space or zone heating appliance or heater rated or decorative fireplace (hearth appliance) and a method of operating a heater including a gas valve, a pressure transducer, a second pressure measurement device, a combustion fan, and a control. The control compares the signal from the pressure transducer to the signal from the second pressure measurement device. If the signals do not sufficiently correspond, the control prevents the gas valve from opening. If the signals sufficiently correspond, the control performs an ignition sequence and opens the gas valve. The control also compares the signal from the pressure transducer to a desired value based on a current input gas rate through the gas valve. If the signal is greater than the desired value, the control decreases power to the combustion fan. If the signal is less than the desired value, the control increases power to the combustion fan. If the signal is less than the desired value, the control turns the gas valve off to cease ignition.
