The Philippines has unique experience in the field of safety standards in refrigeration, air conditioning and heat pumps (RACHP). This report provides the country's experience of adopting international safety standards in air conditioning, refrigeration and heat pumps as national standards. 

05/2024 Publicación - Technical PublicationGreen Refrigeration and Air Conditioning in the Hotel Sector

This publication informs the hotel industry about environmentally, climate and ozone friendly technologies for Refrigeration and Air Conditioning (RAC) devices. Most of the green alternatives presented here are already available in several countries. By “green” technology, it is referred to devices or appliances that have zero impact on the ozone layer, ultra-low or zero Global Warming Potential (GWP below 10) and are also highly energy efficient.

10/2022 Publicación - Technical PublicationCan refrigerants with a GWP below 150 be used for Heat Pumps in Europe?

In the forthcoming report, the viability of applying alternative refrigerants with a GWP < 150 to domestic heat pumps (DHPs) with nominal heating capacities up to 50 kW will be considered. The assessment will reflect the proposed revision to the European F-gas regulation. DHPs currently use a variety of refrigerants, primarily R410A, but also R32, R407C, R404A, R417A, R454B, R454C, R452B, R448A, R449A, amongst others, all of which are medium or high GWP. A number of models already use R290, whilst other alternative refrigerants with GWP < 150 under consideration are R1270, R1234yf and R152a; all of which are flammable. These low GWP alternatives will be assessed, relative to R410A as baseline and R32 as leading medium GWP refrigerant.
