Abstract
An air conditioning system with temperature and relative humidity sensors connected to a computerized control system. The control system acts on preselected stored data to turn on the air conditioning system to maintain the environment within a selected comfort zone. Air flow through finless coils and a preset damper enter a constant speed blower to an air duct. The air in the ducts remains over the dew point. In an alternative arrangement a coil with fins as well as a coil without fins is used.
Claims14
An improved air handling system comprising:
- a relative humidity sensor;
- a temperature sensor;
- a controller;
- a blower;
- a coil without fins;
- said blower when on causing air to flow over said coil through said blower;
- said relative humidity sensor and said temperature sensor connected to said controller;
- said controller having stored data that includes a series of different ranges of relative humidity and temperature, said different ranges constitutional different zones of relative humidity and temperature;
- said controller responding to said relative humidity sensor, said temperature sensor, and said stored data to provide an output signal indicative of the variation of said temperature and said relative humidity compared to a selected range of relative humidity and temperature;
- said controller having output signals to control said blower to turn said blower on and off;
- whereby when the temperature sensed by said temperature sensor and the relative humidity sensed by said relative humidity sensor are outside said selected range said blower is turned on.
