ABSTRACT:
A pressure switch for an energy recovery ventilator. The energy recovery ventilator for exchanging indoor air with outdoor air. The energy recovery ventilator having a housing including a first, and a second input port, and, a first and a second exhaust port, and a heat exchanger core. The energy recovery ventilator further having a first blower for drawing indoor air into said energy recovery ventilator through said first input port, through said heat exchanger core and out said first exhaust port, and a second blower for drawing outdoor air into said energy recovery ventilator through said second input port, through said heat exchanger core and out said second exhaust port. The pressure switch for determines if there is balanced air flow through the energy recovery ventilator. The pressure switch comprises means for sensing the pressure at the heat exchanger core near all four ports. The pressure switch then determines the mean average of the pressure at the core near the first input port and the pressure near the second output port. The pressure switch then determines the mean average of the pressure at the core near the second input port and the pressure near the first output port. By comparing the first mean average with the second mean average, when the mean averages are substantially similar the air flow is balanced.
