Abstract
(EN)
The present invention relates to a device for injecting an equipment protection agent and a heating/cooling system having same, the device comprising: an equipment protection agent storage tank; an equipment protection agent injection pump which is fixedly fastened to the upper part of the equipment protection agent storage tank, and which suctions the equipment protection agent stored in the equipment protection agent storage tank so as to inject same into an expansion tank of the heating/cooling system, thereby maintaining a reference value at a pH concentration of expansion water; a plurality of valves having a first valve, which is provided at a suction port of the equipment protection agent injection pump so as to be inserted into the equipment protection agent storage tank, and a second valve provided at a discharge port; and a pH measurement sensor for measuring the pH concentration of the expansion water of the expansion tank so that the equipment protection agent injection pump is operated according to the measured pH concentration.
