This year, like in many previous ones that were very difficult for this country, our guest was Mr. Gordon Holness, ASHRAE President.

Every year at ASHRAE congress, Mr. Holness mentions the date of our congress and calls his members to attend it.

The congress participants were also greeted by the representatives of international associations: Susanne Pilipou, on behalf of the International Institute of Refrigeration (IIR), Maija Virta on behalf of REHVA, Derrick Braham on behalf of CIBSE (UK) and Carmine Casale on behalf of AICARR (Italy), but also personally, as a participant of our 2nd seminar in 1971.

The congress was attended by delegations from 20 countries. For the first time our guests were the delegations from China and Iran.
