1 The Role of Safety Standard for Phasing down HFCs in RAC Sector Side event on Standards for low-gwp refrigerants: prospects and challenges 15 July, 2016 (Vienna, Austria) Wang Lei Dou Yanwei China Household Electrical Appliances Association (CHEAA)

2 Contents 1. Works on using R290 in China RAC industry; 2. Standard barrier for using R290 in RAC sector; 3. Revising trend of the safety standards; 4. Relation between R290 development and HFCs phase-down.

3 1. Works on using R290 in China RAC industry Risk assessment by Tianjin Fire-fighting institute of Ministry of Public Security fignition of R290 RAC = Reduce the charge amount R & D on using R290 in RAC Heating performance Safety measures Compressor Lines conversion funded by MLF Market Promotion Training on installation and servicing Eco-Label Demo-installing 2 national training centers and 17 local training centers

4 2. Standard barrier for using R290 in RAC sector China has developed a lot of works to use R290 in RAC sector However, Safety concern Cover a series of cooling capacity, at least wall mounted split products. Energy efficiency Heating performance Higher cost Mainly caused by China Standard GB Unreasonable requirements of safety standard IEC

5 IEC : Household and similar electrical appliances - Safety -Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers 1. In 2005, the edition 4.0 of this IEC standard allowed to use flammable refrigerants; 2. In year 2013, the edition 5.0 of this IEC standard was released; 3. In year 2016, the edition 5.1 of this IEC standard was released. For Safety???

7 IEC Year 2013 WG9 Relax the requirements for A2L 1. Relax the requirements for using A2L to reduce the cost of product 2. Make A2L refrigerants can be used in multi split system

8 IEC WG9 Article 7:Marking and Instruction A2L

9 IEC WG9 Article BB:Selection information about refrigerants Existing Standard WG9 proposal Allowable surface temperature = Auto Ignition T < Hot surface ignition Temperature -100K -100K

10 IEC WG9 Article GG:Charge limits, ventilation requirements and requirements for secondary circuits

11 IEC WG16 In year 2014, China NC proposed to establish a WG to discuss A2 and A3 refrigerants in Geneva meeting;(refused) In year 2014, China NC proposed again to establish a WG to discuss A2 and A3 refrigerants in New York meeting; (Discussed next meeting) In year 2015, China NC, together with UK NC, proposed to establish the new WG; (Approved)

12 UL 484 Current standard Charge size:140g Revising to Charge size:114g Safety R290

13 It seems that R290 becomes as the mouse in street in the safety standards There are three major measures in the standards to kill R290: 1. Limit charge amount as lower as it can not be used Impossible to meet in units with large cooling capacity Reduce the performance of R290 in the appliances 2. Increase cost - difference between A3 and A2L Reduce competitive of R290 appliances in market 3. Make image - difference between A3 and A2L Affect on selection of the consumer

14 WG9 focuses on A2L will circulate CDV soon in IEC SC61D member countries WG16 is in the conceptual level and 4 meetings organized since September 2015

15 4. Relation between R290 development and HFCs phase-down Two main refrigerants in RAC sector, R22 and R410A, will be controlled in the near future. It will be a big challenge for the development of the industry.

16 4. Relation between R290 development and HFCs phase-down Theory analysis, using R410A consumption in China RAC sector. Change all R410A to other refrigerants. Consider the charge amount reduction. 35% 15% In reality, R410A can be replaced gradually. According to our scenarios analysis, 20% or 15% target can be met only by using gases with GWP lower than 150. Only the natural gas can meet the schedule of HFC phase-down.

17 5. Summary 1 Related safety standards will be revised more and more strictly for hydrocarbon 2 Related safety standards will be more and more unfair between A2L and A2/A3 refrigerants 3 The safety standard will construct the technical barrier for using hydrocarbon and/or increase the cost for using hydrocarbon 4 In China RAC sector, HFC phase-down will be very difficult to be met without development of hydrocarbon
