AIR TEMPERATURE CONTROL SYSTEM

摘要

A multizone room air temperature control system comprises a thermostatically controlled louvered vent unit fitted to the mouth of the preexisting air duct register of the heating and air-conditioning system, in each room whose temperature is to be controlled. A continuously energized reversible shaded pole motor connected to the thermostat automatically opens and closes the vent louvres in response to room air temperature changes to thereby introduce or shut off the supply of either warm or cold air into the room for regulating the room air temperature independently of the other rooms.
