HFOS AS HCFCS SUBSTITUTES DEMONSTRATION PROJECTS RECEIVE GREEN LIGHT FROM THE MONTREAL PROTOCOL MULTILATERAL FUND

HFOS AS HCFCS SUBSTITUTES DEMONSTRATION PROJECTS RECEIVE GREEN LIGHT FROM THE MONTREAL PROTOCOL MULTILATERAL FUND

06.09.2015

At its 74th session, the Montreal Protocol Multilateral Fund Executive Committee agreed to fund several demonstration projects in developing countries (Art. 5 of the Montreal Protocol). These demonstration projects will test the use of HFOs and HFO blends as substitutes for HCFCs in PU insulating foam blowing agents and as air conditioning working fluids.

UNIDO introduced two Saudi Arabia preparation projects :

– the first, based on HFOs such as HFO-1233zd(E), for the phase-out of HCFCs as insulating foam blowing agent in applications under high ambient temperatures for refrigerating appliances. Besides a very low GWP of 1, HFOs provide a higher insulation performance of 6-8% and a higher yield (lower raw material costs).

– the second one for promoting HFO-based low-GWP refrigerants for the air-conditioning sector in high ambient temperatures. HFO blends will be tested such as R-444B or R447A.

UNDP introduced an India project for the development and evaluation of spray foam polyols systems under high ambient temperatures for buildings using HFO-1233zd(E) as blowing agent.

A World Bank presented Columbia project for the use of HFOs for discontinuous panels and spray foam was deferred to the next MLF ExCom meeting.
