2. CAPACITY TABLES
2-5. Correction by antifreeze solution concentration
In HYBRID CITY MULTI system, antifreeze solution should be used to prevent the system from freezing. Refer to the following
graphs for the capacity correction by antifreeze solution. Refer to 2-5-1 for antifreeze solution concentration, 2-5-2 and 2-5-3 for
capacity correction by antifreeze solution concentration.
2-5-1. Antifreeze solution concentration
Use propylene glycol solution for antifreeze.
Refer to the following graph to estimate the antifreeze solution concentration required for freeze protection.
DipSW setting (SW5-4 and 5-5) is required in HBC unit depending on the antifreeze solution concentration.
Refer the table A for the setting.
2-5-2. Capacity correction by antifreeze solution concentration (cooling)
2-5-3. Capacity correction by antifreeze solution concentration (heating)
