INDOOR CLIMATE CONTROLLER SYSTEM ADJUSTING BOTH DRY-BULB TEMPERATURE AND WET-BULB OR DEW POINT TEMPERATURE IN THE ENCLOSURE

摘要

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 withi n 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 o f both the dry-bulb and the humidity temperature values. This permits control of bo th enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures th e humidity temperature, the humidity temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure.
