text: Climate in refrigeration
  From the international agreement on climate change in recent years, a number of regulations have emerged that affect the operation of refrigeration systems. Among other things it is about to replace ozone-depleting substances such as CFCs and HCFCs (in accordance with the Montreal Protocol) and to limit the greenhouse exit-promoting substances such as CFCs and HFCs in the atmosphere (the Kyoto Protocol).
  The operators of the facilities to be made for the implementation of Regulation personally liable, regardless of whether they are owners of assets or manager have a responsibility.
  Logbook for refrigeration and air conditioning systems
  Plant operators of stationary refrigeration and air conditioning systems 3 kg refrigerant charge (CFC, HCFC, HFC, HFC) have the duty to keep a log of each installation and keep this for 5 years.
  For refrigeration systems using ozone-depleting refrigerants (such as R22) has been around since the introduction of CFC-Halon Prohibition Ordinance in 1991 the obligation to keep records of the amounts of refrigerants records.
  In the chemical ozone regulation in November 2006 is provided in addition to record the inspections and maintenance (including checking for leaks and repair work), as well as the type and amount inserted or recovered refrigerant. The operator must keep the records for at least five years after their creation, and the competent authority upon request.
  Since 4 July 2007, operators of refrigeration and air conditioning systems have to lead with PFC and HFC refrigerants duty records, namely:
