APPARATUS FOR AIR-COOLING USING A COOLING TOWER IN WINTER SEASON

摘要

The present invention relates to an outdoor air cooling apparatus using a cooling tower in winter, and more specifically, by cooling the cold water returned from a cooling load side using a cooling tower, it is possible to actively utilize low temperature outdoor air for cooling in winter to improve energy efficiency. It relates to an outdoor air conditioner.;The outdoor air cooling apparatus using the winter cooling tower of the present invention includes a refrigerator configured to cool the cold water passing through the evaporator, comprising a compressor, a condenser, and an evaporator, a return header for returning cold water from a cooling load side, and supplying cold water to the cooling load side. A cold water circuit composed of a supply header to circulate cold water; And a cooling water circuit configured to cool the heat exchanger by cooling the coolant by exchanging the coolant with outside air, wherein the cooling water is circulated through the condenser of the freezer. A cooling water outlet pipe connected to the cooling water outlet; A coolant inlet pipe connected to the freezer outlet side of the coolant circuit to introduce coolant; A cold water outflow pipe and a cold water inflow pipe that sequentially connect to the return header side of the cold water circuit to allow the cold water to flow in and out; A heat exchanger connected to the cooling water outlet pipe and the cold water outlet pipe to receive and exchange heat with the cooling water and the cold water, and to discharge each of the cooling water inlet pipe and the cold water outlet pipe; Cooling water flow rate adjusting means provided in the cooling water circuit to adjust a flow rate of the cooling water flowing out to the cooling water outlet pipe; It is characterized in that it further comprises; cold water flow rate adjusting means provided in the cold water circuit for adjusting the flow rate of cold water flowing out to the cold water outlet pipe.;Cooling Units, Cooling Towers, Heat Exchangers, Refrigerators
