Abstract

An humidification apparatus establishes geometric properties for humidity loss from a structure relative to inside and outside temperatures and historic performance of that building structure. The humidification apparatus also stores data establishing acceptable relative humidity ranges for the internal and external ambient temperature conditions to which the building structure is exposed. The humidification apparatus obtains weather forecast data for the geographic location of the building. A user inputs a desired level of relative humidity. The humidification apparatus controller then adjusts humidity inside the building according to that input and according to the permissible humidity range for the building in the prevailing external temperature conditions and the weather forecast data.

Dependent claims

An humidity control apparatus for a building comprising:

at least a first temperature sensor mounted to monitor temperature inside said building;
at least a first humidistat at which a set humidity value is input, and at least a first humidity senor mounted to monitor humidity inside said building;
a source of weather forecast data input;
a memory of thermal properties of said building;
and a processor;
said processor being operable to receive input values from at least said first temperature sensor;
at least said first humidistat and said source of weather forecast data input;
said processor being operable to monitor observed temperature and observed humidity at least at said first temperature sensor and at least at said first humidity sensor respectively;
said processor being operable to make a forward projection of humidity level within said building as a function of said weather forecast data input;
and
said control apparatus being operable to output environmental control signals to adjust humidity within said building toward said forward projection of humidity level.
