    摘要: A bipolar ionizer comprising an electronic circuit, microprocessor, and step-up transformer providing high-voltage signals to carbon-fiber electrodes producing bipolar ion concentrations greater than +/−200 million ions per cubic centimeter. The bipolar ionizer monitors, reduces, and converts high-voltage signals to feedback signals used by the microprocessor to vary a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer output voltage to consistently maintain an unbalanced high-voltage output ratio less than 80 percent, balanced bipolar ion concentration ratio greater than 80 percent, and zero ozone concentration over a range of electrical signal inputs. The microprocessor calculates and reports bipolar ionizer concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the bipolar ionizer and adjusts the positive/negative DC high-voltage signals and bipolar ion concentration when VOC concentrations are above a threshold.

    摘要: An efficient fan controller for Heating Ventilating Air Conditioning (HVAC) systems including at least one electrical signal input from thermostat or equipment control terminals with a microprocessor to control a switching device connected to a signal output to control a fan relay and operate a system fan. The microprocessor is configured to monitor a thermostat call for cooling/heating duration and determine a variable fan-off delay based on the cooling cycle or heating cycle duration, and at an end of a cooling/heating cycle energize the fan relay to operate the system fan for the variable fan-off delay. The fan controller can include a heat pump detection signal input and electrical signal inputs to connect to a thermostat heat terminal, heat pump reversing valve terminal, or compressor terminal. The fan controller can also include a normally-closed relay connected to the switching device to maintain continuity between the fan signal input and output.

    摘要: Apparatus and methods are disclosed for a fan controller. The fan controller determines HVAC system type and heating or cooling mode for gas furnace, heat pump, electric resistance, and hydronic heating, ventilating, and air conditioning (HVAC) systems. For gas furnace heating systems, the apparatus and methods include energizing the blower fan from a lower fan speed used for heating by the furnace-fan controller to the high-speed used for cooling by the fan controller after fan-on delay time P1 to increase delivered heating capacity, satisfy the thermostat sooner and save heating energy. For heat pump, electric resistance, and hydronic heating systems the apparatus and methods include energizing the fan relay after a short fan-on delay time P0 based on previous off-cycle duration P11. For all these HVAC systems, the apparatus and methods vary extended fan-off time delay P2 as a function of cool-source operational time P4 or heat-source operational time P3.

    摘要: A method for efficient control of a heater ventilation fan. The method includes switching the heater ventilation fan from low speed to high speed after a brief period P1 following starting, and continuing heater ventilation fan operation for a variable period of time P2 after the heat source has stopped. The period P1 is preferably about four minutes, and the period P2 is determined by the duration of heating and is generally between two and four minutes. Operating the heater ventilation fan at high speed improves heat transfer and efficiency while the heating system is operating, increases warm air movement to the space, satisfies the thermostat set point temperature in less time, reduces heating system operation, and reduces energy use. Continuing heater ventilation fan operation after turn-off maximizes recovery of additional heat from the heat exchanger to improve overall efficiency, extend the off cycle time, and save energy.
