Problems solved by technology

This may confuse users
Additionally, functions that require multiple controls to control the same HVAC system can sometimes have conflicting results, thus causing the system to operate at a less than optimal 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]FIG. 1 illustrates a schematic diagram of a building HVAC system 10 . A single integrated centralized control device 12 may control multiple indoor environmental characteristics based on the actual environmental characteristic E sensed by at least one environmental sensor 14 and user input U input to the user interface 16 by the user. A single integrated centralized control device 12 controls indoor environmental characteristics by selectively activating and / or deactivating at least one device 18 .

[0030] FIG. 2 illustrates 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 the actua...

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 central control 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, the single 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...
