Abstract

A method and apparatus for controlling a temperature-regulated zone utilizing a thermal balance temperature control system. The thermal balance control system is a dynamic real time control system that measures the sensible thermal load in the zone, and directly regulates the BTU output of the HVAC package to balance such output with the measured sensible thermal load.

Description

[0001] This application claims the benefit of U.S. Provision Application Ser. No. 60 / 512,410 filed on Oct. 17, 2003.BACKGROUND OF THE INVENTION

[0002] The present invention relates to a temperature control system and, more particularly, to a system which directly regulates the system output to balance such output with the sensible thermal load.

[0003] Heating, ventilating and air-conditioning (HVAC) systems are used to both heat and cool the air within an enclosure, e.g., a building or zone within such building. An HVAC system typically includes a heating unit, a cooling unit, a supply air fan, a supply duct for directing air into the enclosure, and a return duct for removing air from the enclosure. It will be appreciated by those skilled in the art that HVAC systems are generally designed to operate in one of three modes: a heating mode to heat the enclosure, a cooling mode to cool the enclosure and a economizer mode to ventilate the enclosure. The economizer mode typically utilize...

Embodiment Construction

[0022] As discussed more fully hereinbelow, the present invention is directed to a method and apparatus for controlling a temperature-regulated zone utilizing a thermal balance temperature control system. The thermal balance control system is a dynamic real time control system that constantly measures the sensible thermal load in the mentioned zone, and directly regulates the BTU output of the HVAC package to balance such output with the measured sensible thermal load, thus providing a state of system equilibrium. The system will continue to operate in this equilibrium state (without time cycling of any heating / cooling components) until the system measures a change in the sensible thermal load within the mentioned zone.

[0023] The sensible thermal load is the amount of deviation (measured in degrees) between the set point temperature for the zone and the actual zone temperature. When the actual room temperature is above the set point temperature, the sensible thermal load is a cooli...
