Abstract
An air conditioning system comprises first (8) and second (13) heat exchangers having first and second counterflow passages, a twin bed gas purification unit comprising (i) first (22) and second (23) parallel filter beds, (ii) valve means for directing air from an inlet to flow through the first filter bed and for directing purified air from the first bed so that a greater proportion flows to an outlet while a smaller proportion flows in counter direction as purge gas through the second bed and then to a purge outlet, (iii) a plurality of heater units (30) at spaced apart locations along each of the filter beds for heating a gas as it flows through the heater bed, and (iv) means for controlling the heater. Connecting means can direct air to flow from the air intake through the first passage of the first heat exchanger (8), through the first passage of the second heat exchanger (13) and through the air/water separator (17) to the inlet (25) of the purification unit, then from the outlet (26) of the purification unit through the second passage of the first heat exchanger (8) and through the heater (47) for delivery into the vehicle or other space in which the system is fitted.
