Abstract

A system for determining a humidity level for an area of interest (AOI) is disclosed. The system comprises a first sensor operable to monitor ambient air temperature outside the AOI, a second sensor operable to monitor dew point temperature within the AOI, and a processing device in communication with the first sensor and the second sensor. The processing device comprises one or more processors coupled to a memory storing instructions executable by the one or more processors, wherein the processing device is configured to receive, from the first sensor, the ambient air temperature being monitored outside the AOI, receive, from the second sensor, the dew point temperature being monitored within the AOI, and determine a humidity level to be maintained within the AOI based on the received ambient air temperature and the received dew point temperature.

Claims (33)

1 . A system for determining and maintaining an optimum humidity level for an area of interest (AOI), the system comprising:

a first sensor operable to monitor ambient air temperature outside the AOI;

a second sensor operable to monitor dew point temperature within the AOI; and

one or more processors in communication with the first sensor and the second sensor, wherein the one or more processors are coupled to a memory storing instructions executable by the one or more processors, and wherein the one or more processors are configured to:

receive, from the second sensor, the dew point temperature being monitored within the AOI;

determine, based on (i) the received ambient air temperature and (ii) the received dew point temperature, the optimum humidity level to be maintained within the AOI, wherein the optimal humidity level to be maintained is determined in accordance with a database mapping the received ambient air temperature and the received dew point temperature to the optimum humidity level to maintain an apparent temperature felt within the AOI; and

operate one or more of an HVAC system and an air humidification system associated with the AOI to maintain the determined optimum humidity level within the AOI.

2 . The system of claim 1 , wherein the database comprises one or more known outdoor air temperatures, one or more known dew point temperatures, and a corresponding predetermined humidity level of the one or more outdoor air temperatures and the one or more known dew point temperatures, to determine the optimum humidity level to be maintained within the AOI, and wherein the determined optimum humidity level is the corresponding predetermined humidity level after the mapping.

3 . The system of claim 1 , wherein the one or more processors are operatively connected to the HVAC system associated with the AOI, and wherein the one or more processors are further configured to transmit data comprising the determined optimum humidity level for the AOI to the HVAC system.

4 . The system of claim 1 , wherein the one or more processors are in communication with the air humidification system associated with the AOI, and wherein the one or more processors are further configured to transmit data comprising the determined optimum humidity level for the AOI to the air humidification system.

5 . The system of claim 1 , wherein the first sensor is positioned outside the AOI and the second sensor is positioned inside the AOI.
