METHOD FOR CONTINUOUSLY REGULATING THE LEVEL OF THE COMPOUNDS FOR FREEZING POINT DEPRESSION IN ENERGY SYSTEM, SUCH AS HEAT RECOVERY SYSTEMS IN BUILDINGS

摘要

A method for removing compounds for freezing point depression in a heat recovery system in a building, which heat recovery system comprises a first circuit (1 ) with process water, a first heat exchanger (2) and a second heat exchanger (3), where a fraction of the process water from the first circuit (1 ) is withdrawn to a second circuit (5) that is connected in parallel with the said first circuit, which the second circuit comprises a evaporation tank (8) for separation of water from the compound for freezing point depression, which the evaporation tank is connected to a ejector (7) and to a storage tank (10; 13).
