Patent ID: 8356760

Claim:
An HVAC control system to control a heating system and a cooling system in order to adjust apparent temperature to a desired apparent temperature, comprising: a temperature sensor to obtain an air temperature measurement and to generate a dry bulb temperature value from the air temperature measurement; a humidity sensor to obtain a humidity measurement and to generate a relative humidity value from the humidity measurement; an input interface to receive a desired apparent temperature value from a user; a controller to control the heating system and the cooling system, said controller in communication with the heating system, said controller in communication with the cooling system, said controller to receive the dry bulb temperature value from said temperature sensor, said controller to receive the relative humidity value from said humidity sensor, said controller to receive the desired apparent temperature value from said input interface, said controller to calculate a current effective temperature value based on the dry bulb temperature value and the relative humidity value, wherein said controller calculates the current effective temperature value through an algorithm that generates effective temperature values as outputs of a function that uses dry bulb temperature values and the relative humidity values as inputs, said controller to calculate a target temperature value based on the current effective temperature value, the dry bulb temperature value, the relative humidity value, the desired apparent temperature value, and said algorithm, such that adjusting the dry bulb temperature value to the target temperature value yields the desired apparent temperature value according to said algorithm, said controller to activate the heating system if the target temperature value is greater than the dry bulb temperature value, said controller to activate the cooling system if the target temperature value is less than the dry bulb temperature value.
