초록

An air curtain providing an air stream across a doorway between areas of relatively cool and warm air masses and continuously monitoring the condition, e.g., temperature, pressure and flow rate, of one or both air masses and the air stream. The air curtain has a control system including an electronic controller operating a heater and fan and receiving air characteristic inputs from temperature, pressure and flow rate sensors. The controller monitors these inputs continuously and processes them to operate the heater and fan according to algorithms designe...
