ABSTRACT:
A method of cooling air in a space and air conditioning apparatus for carrying out this method. Primary air at a temperature much below the temperatures used in conventional systems, is mixed with secondary drawn from the space, the mixture then being introduced into the space in order to cool it. Mixing takes place in a venturi diffuser or mixing device which enables a high induction ratio to be achieved. The system is more efficient and less costly to install and operate than the conventional systems. In one embodiment, some or all of the primary air may be drawn from the space, thereby avoiding the wasteful discharge of cold air to atmosphere.
