<p>The heating and ventilating system with a recuperative or regenerative heat exchanger system combined with the air supply and exhaust ducts, also includes a humidifying system with a water jet spray chamber with an air cooler. The control circuit is a triple system with two temperature control branches and an enthalpy branch. This includes an enthalpy monitoring device to control the enthalpy of the air supplied to the jet chamber including control of the heat recuperator. Between them is a heater and an air flow control flap which are operated sequentially together with the heat recuperator. The enthalpy system includes temperature and humidity sensors between the heat recuperator and jet chamber connected to a comparison system for nominal and actual values and an equaliser to operate the control motors for the system.</p> |
