HUMIDEX CONTROL SYSTEM PREFACE The requirement arose to maintain the humidex level below thirty, based on the Occupational Health Clinic for Ontario Workers chart on page 8.125 of this report. A control system was developed controlling the occupied space humidex level below thirty, while using enthalpy comparison control of return air to outdoor air assuring the lesser cooling load on the cooling coils. As per the graph on page 8.124 both the humidex target and enthalpy targets were met.
