Problems solved by technology

[0009] While it is known to combine temperature control and humidifier control into a single controller (such as a hygrostat), the combination of a ventilator usually requires the addition of a second independent humidistat control. Likewise, providing full control over all indoor environmental characteristics of a building structure Year-round control requires the user to interface with at least two controls to control different functions of the same HVAC system. This can confuse the user. Additionally, functions that require multiple controls to control the same HVAC system can sometimes produce conflicting results , thus causing the system to run at a suboptimal performance level.
[0010] In summary, controlling indoor environmental characteristics such as indoor temperature, indoor relative humidity, and indoor fresh air level has thus far required the use of multiple control devices, which is not ideal

Embodiment Construction

[0029] figure 1 Illustrated is a schematic diagram of a building HVAC system 10. A single integrated centralized control device 12 can control multiple indoor environmental characteristics based on an actual environmental characteristic E sensed by at least one environmental sensor 14 and a user input U input to a user interface 16 by a user. A single integrated centralized control device 12 controls indoor environmental characteristics by selectively activating and / or deactivating at least one device 18.

[0030] figure 2 Illustrated is a detailed schematic diagram of a building HVAC system 10 including a single integrated centralized control device 12 . A single integrated centralized control device 12 receives actual environmental input from multiple sensors. The indoor temperature sensor 20, the indoor relative humidity sensor 22 and the outdoor temperature sensor 24 can be used to input the actual indoor temperature (T I ), indoor relative humidity input (H I ) and t...

Abstract

HVAC systems are employed to control the indoor environmental characteristics of a building structure to make it comfortable for its inhabitants. An HVAC system includes one single integrated centralcontrol to regulate an indoor temperature level, an indoor relative humidity level and an indoor fresh air level of a building structure during both a heating season and a cooling season. Further, thesingle integrated central control is operable to selectively activate / deactivate an indoor blower to control a sensible ratio within a building structure. In addition, a protection feature for avoiding condensation on the interior surfaces of the building structure is included as an user selectable option.

Description

[0001] This application claims priority to US Provisional Application No. 60 / 537,528, filed January 20, 2004, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] This application relates to indoor central heating, ventilation, and air conditioning (HVAC) systems in which the control of indoor temperature, indoor relative humidity, and indoor fresh air level are combined into a single integrated centralized control device, which is controlled during the heating and cooling seasons The device can be used to manage the indoor environment. Background technique [0003] HVAC systems are used to control the indoor environmental characteristics of building structures for occupant comfort. A typical HVAC system includes a temperature control device, or thermostat, and one or more humidity control devices called a humidistat. [0004] A thermostat is used as a control device to regulate the temperature in a room. The thermostat sens...
