The present invention provides a water quantity adjustment device with which, when a plurality of plurality of water-retaining materials are arranged, adjustment is facilitated by equalizing the quantity of water supplied to each water-retaining material and visualizing adjustment of the equalization of the quantity of water supplied to each water-retaining material. Provided is an auxiliary cooling system for a condenser in which a plurality of outdoor units (1) are arranged in parallel in a horizontal direction and water-retaining materials (30) are arranged in close proximity to each other on the windward side of a condenser (3) of the outdoor units (1), wherein: branch pipes (33), which branch off from a water supply pipe (15) and serve to supply water to the water-retaining materials (30), are provided; a valve (46) that adjusts the quantity of water supplied to the water-retaining materials (30) is interposed in each branch pipe (33), and a visualization device (70) that serves as a pressure adjustment chamber is interposed on the downstream side of the valve (46); a downstream valve (46) that is interposed at the end of the water supply pipe (15) is configured for flow rate adjustment whereby the quantity of water supplied to a downstream water-retaining material (30) via a downstream visualization device (70) that is interposed on the downstream valve (46) side is adjusted while watching the state of wetness of the downstream water-retaining material (30); and an upstream valve (46) that is located upstream of the downstream valve (46) is configured for flow rate adjustment whereby the quantity of water supplied to an upstream water-retaining material (30) is adjusted such that the water level in an upstream visualization device (70) that is interposed on the upstream valve (46) side is the same as the water level in the downstream visualization device (70). |
