Abstract

A dynamic environmental control system for managing the environment in a super insulated tightly sealed home which has a heat recovery ventilator connected to a forced air heating system for ventilation. The system controls indoor temperature, humidity and fresh air levels as well as temperature gradients using a heat recovery ventilator, heater and an air ventilation fan. The system can initiate operation of the heat recovery ventilator to exchange moist and polluted inside air for drier fresher outside air to control both inside moisture and air pollutant levels. Air exchanges can be initiated by an internal system timer, manually by building occupants or by the system in response to humidity levels inside the home. The system will determine the moisture contents of inside and outside air and will only attempt to exchange air to lower inside humidity levels when the outside air contains less moisture than the inside air. The system can operate to minimize window glass condensation caused by excess inside humidity or to minimize humidity levels. A seven day, four temperature setback thermostat is incorporated in the system to control operation of the heater. There is also a temperature gradient monitor which will operate the air ventilation fan without the heater to redistribute air inside the home and minimize temperature gradients.
