5.7.5 Water supply specifications Analyze the water It is the user’s responsibility to establish the quality of the water and make sure that this is compatible with the materials used in the exchangers. The quality of water significantly affects the operation and the life of the exchangers. The first step in planning the treatment of the water is chemical analysis, which must be performed by quali- fied personnel from specialist organizations.
Page 85 5.7.7 Prevent freezing for chiller or freecooling chiller Prevent freezing In winter, if the system is stopped, the water inside the exchangers can freeze damaging the system by glycol irreparably. Thus, it is recommended to use glycol mixtures: please consider the different outputs and power absorp- tion by the chiller, the pump sizing and the performance of the system terminals/conditioners).
