• The COP(coefficient of performance)of 20-year-old equipment is about 4.0; for today's equipment, it is more than 6.0.
• For the future, natural cooling media such as ammonia and CO2 are desirable.
• Select a CFC substitute when upgrading turbo chiller
• Select a specified CFC when changing only the cooling medium in an existing turbo chiller
  The COP will fall slightly

In accordance with the regulations of the Act Concerning Withdrawal and Destruction of CFCs enforced in April 2002, equipment users are required to withdraw and destruct CFCs in an appropriate way.
