During the European Automotive Air Conditioning Convention on 20 and 21 September in Frankfurt, Frank has provided a workshop. The subject was the importance of reliable diagnostic tools and workshop information systems for the automotive air conditioning specialist. In today\'s hybrid vehicles, the cooling of the HV battery and power electronics become increasingly important. With the advent of fully electric vehicles and vehicles with a range-extender, we can truly say that the cooling and heating components are crucial. When future automotive air conditioning specialist wants to play any role of importance, he will have to go along with such developments. This will require an investment in knowledge and equipment.
