Abstract

The invention relates to systems of ventilation and air conditioning and can be used in office, production and dwelling premises, constructions and buildings. The system includes inflow and exhaust air ducts, central station that has filtration chamber, chambers of inflow and exhaust ventilators, chamber of heat exchange with plate recuperative heat exchanger, means for supply and transfer of additional heat or cooling energy to inflow outer air connected to power sources, indicators of control of temperature of inflow and exhaust air, shutoff-control means and control system. Besides that are provided chambers of noise absorption and chambers-collectors one of which has drive air multiple-louvre damper for control of exhaust air. Means for supply and transfer of additional heat or cooling energy to inflow outer air is placed in chamber of heat exchange and are arranged as multi-contour heat exchanger. Those have connected in sequence heat exchange contours of heat carrier with liquid, heat carrier with antifreeze and heat carrier with cold agent, at that the two last ones are connected to device for utilization of condensate. By direction of motion of inflow outer air in central station chamber of noise adsorption is placed, filtering chamber, chamber of inflow ventilator, plate recuperation heat exchanger and contour of heat carrier with antifreeze agent, chamber-collector, chamber of noise adsorption, mean for measurement of flow rate of inflow outer air and shutoff-control mean. In direction of flow of exhaust air from object of servicing shutoff-control mean is installed and mean for measurement of flow rate of exhaust air, noise adsorption chamber, chamber-collector with drive air multiple-louvre damper and depending on position of drive air multiple-louvre damper circuit of heat carrier with cold agent of plate recuperation heat exchanger and circuit of heat carrier with cold agent, chamber of exhaust ventilator and noise adsorption chamber. In heat exchange chamber between the circuit of heat carrier with antifreeze agent and chamber-collector ionization chamber with needle coronary electrodes is placed. Logical controller and cabinet with power executive devices are placed in control chamber, and remote control panel is placed in servicing object. The invention promotes increase of power effectiveness and reliability of conditioning system.
