Annex 54 organized two workshops for \u201cHeat Pumps for Low-GWP Refrigerants\u201d at the 25th IIR Conference ICR 2019 in Montr\u00e9al, Canada on 26th August. Seven presentations were held by experts from the participating countries in the Annex and invited speaker from Germany. Here is summary of presentations.<\/p>\n
    \n
  1. Dr. Piotr A. Domanski from NIST, USA presented for \u201cScreening for Next Generation Refrigerants.\u201d He presented screening results of low-GWP refrigerants and concluded that there is no direct HFO replacement candidate for R-410A and tradeoff between GWP and flammability is needed, and recommended to redesign new equipment.<\/li>\n
  2. Dr. Xudong Wang from AHRI, USA presented for \u201cEnsuring a Safe Refrigerant Transition.\u201d He introduced AHRI\u2019s Low GWP Alternative Refrigerants Evaluation Program (AREP)\u201d and presented US pathway for using flammable refrigerants. He shared AHRTI\u2019s project 9007 on flammable refrigerants for whole room scale testing of A2L and A3 refrigerants to understand the ignition event severity not probability of event. He suggested assessing refrigerant detector characteristics for use in HVACR equipment, combustion byproducts risk study and accessing the effectiveness of mitigation requirements as future research projects.<\/li>\n
  3. Professor Luca Molinaroli from Pilitenico di Milano presented for \u201cExperimental Analysis of the Use of R134a, R1234ze(E) and R1234yf in a Small Water-to-water Heat Pump.\u201d He presented test results and concluded that the heating capacity of the heat pump working with the two HFOs could be matched to the R134a level by increasing the compressor speed but the COP is further reduced and R1234yf exhibited higher COP than R1234ze(E). He planned for testing of R450A and R513A.<\/li>\n
  4. Professor Eiji Hihara from University of Tokyo presented for \u201cRisk assessment of A2L refrigerants implemented in Japan.\u201d He presented Japanese collaborative research results for risk assessment of A2L refrigerants and mentioned that the risk assessment for the safe use of flammable gases such as hydrocarbons is underway.<\/li>\n
  5. Dr. Samuel Yana Motta from Honeywell, USA presented for \u201cLow GWP Refrigerants for Heat Pump Systems.\u201d He compared four alternatives with R410A and suggested that R-466A (GWP<750) is closest match to R410A\u2019s performance amongst A1 class refrigerants while using the same size\/design of compressor and heat exchangers.<\/li>\n
  6. Dr. Lena Schnabel from Fraunhofer Institute for Solar Energy Systems presented for \u201cR290 Researches at Fraunhofer ISE\u201d. She presented efforts for charge reduction of R290 in heat pumps and leakage prevention, detection and control.<\/li>\n<\/ol>\n
