-12- LIQUID REFRIGERATION SYSTEM FOR AN ENCLOSURE TEMPERATURE CONTROLLED OUTDOOR COOLING OR PRE-CONDITIONING ABSTRACT OF THE DISCLOSURE An economical energy-saving air-conditioning system for conditioning air in an enclosure requiring year-around environmental control. An outdoor heat exchangeris operative in a recirculating liquid closed-loop cooling system which utilizes cooler outdoor temperatures without affecting other environmental aspects of the en- closure. A temperature controlling arrangement provides continuous free outside cooling when the outside temperature is in the order of 35° to 40° F. or less; and provides free pre-conditioned cooling of the air when the outside temperature is in the range of about 35° to 65° F. The closed-loop comprises conventional components for summer temperature cooling; and, in less-than summer tempera- tures, the present invention utilizes the outside heat exchanger to provide coolliquid to a free cool coil positioned in the air stream advance of an evaporator coil. Reheat for dehumidification is provided in an improved embodiment - again the reheat is taken from the waste heat of the refrigeration system.
