Abstract:
1. An improved air conditioner system for controlling a desired temperature and a reduced humidity level in a space to be environmentally controlled, the air conditioner system comprising: a first air flow path through which, outside ambient air flows; a second air flow path for processing air from a space to be environmentally controlled back to the space; said first air flow path being separate from said second air flow; refrigerant circuit means for circulating a refrigerant fluid through heat exchangers in the first and second air flow paths, the refrigerant circuit means including a compressor; the first air flow path comprising an ambient outdoor air inlet means in air flow communication with forced air flow means for directing the flow of outdoor ambient air through the first air flow path and for discharging said ambient outdoor air through ambient outdoor air discharge means; heat exchanger means for transferring heat from the refrigerant fluid being circulated inside tubing comprising said heat exchanger means, to said ambient outdoor air passing through said heat exchanger means over said tubing; the second air flow path comprising a room air return inlet means in air flow communication with forced air flow means for directing the flow of room air returning from the space to be environmentally controlled, through the second air flow path, and back to said space through room air inlet means for discharging the flow of air exiting the second air flow path; first heat exchanger means for transferring heat from the room air to the refrigerant fluid being circulated inside tubing comprising said first heat exchanger means, thereby cooling and dehumidifying said room air that has passed through a filter means; second heat exchanger means, downstream of the first heat exchanger means, for transferring heat from the circulating refrigerant fluid inside tubing comprising said second heat exchanger means, said refrigerant fluid being at a raised temperature after exiting the compressor, the heat being transferred to the room air exiting the first heat exchanger means; and the refrigerant circuit means further comprising: wherein the refrigerant fluid circulates from the compressor through the anti-migration control means, through the tubing in the second heat exchanger means in the second air flow path, through the tubing in the heat exchanger means in the first air flow path, through the expansion means, through the tubing in the first heat exchanger means in the second air flow path, through the anti-floodback control means and back to the compressor to complete the refrigerant circuit means.
