Claim:
1. A sleeping space air conditioner, comprising: (a) a quiet, low powered conditioned air flow generating means configured to provide a conditioned air flow; and (b) means defining a sleeping space into which the conditioned air provided by the conditioned air flow generating means is adapted to be delivered from a foot end of the sleeping space in a manner which maximizes contact between the conditioned air and a person or persons in the sleeping space, the means defining the sleeping space including: the means defining the sleeping space being adapted to surround a bed in the sleeping space and configured to minimize passage of the conditioned air from the sleeping space through the upper air pervious section or other leakage paths, the lower air impervious section extending to a height above a sleeping surface of the bed at a head end of the bed opposed to said foot end sufficient to contain the conditioned air as it moves towards and returns from the head end of the sleeping space, and the lower air impervious section extending to a sufficiently increased height above the sleeping surface at the head end to allow the direction of air flow to reverse towards said foot end without substantial loss of conditioned air through the upper air pervious section, wherein the conditioned air flow generating means includes: wherein airflow velocity of conditioned air from the nozzle is sufficient to reduce the tendency of the air flow to mix with surrounding air such that higher airflow velocity is maintained at a greater distance from the nozzle; and wherein horizontal movement of conditioned air from the nozzle is stopped by the head end of the lower air impervious section of the sleeping space and upwardly displaces warmer, less dense, air so as to gain additional perceived comfort, wherein the conditioned air flow generating means includes a return air intake having a sufficient area of pervious material serving as an air filter, the pervious material being configured and arranged to maintain an air intake velocity sufficiently low to inhibit warm air above the conditioned air to enter the air intake.
