Indoor climate controller system adjusting both dry-bulb temperature and wet-bulb or dew point temperature in the enclosure
First Claim
1. Apparatus for cooperating with a controller for a climate control system for modifying the temperature and humidity of air within an enclosure, said controller activating the climate control system responsive to a composite error value encoded in a composite error signal falling within a preselected range of error values, said apparatus comprisinga) a humidity sensor providing a humidity temperature signal encoding at least one of the wet-bulb temperature and the dew point temperature;
- b) a temperature sensor providing an air temperature signal encoding the dry-bulb temperature value;
c) a memory recording a dry-bulb temperature set point value and a humidity temperature set point value, and providing a set point signal encoding the dry-bulb and humidity temperatures set point values; and
d) error computation means recieving the humidity and air temperature signals and the set point signal, for computing the composite error value as a function of the values encoded in the humidity and air temperature signals and the set point signal, and for encoding the composite error value in the composite error signal.

Abstract
A controller for a climate control system has a humidity (wet-bulb or dew point) temperature sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity temperature value is used in connection with the dry-bulb temperature to generate a single error signal which is a function of both the dry-bulb and the humidity temperature values. This permits control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the humidity temperature, the humidity temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure.
