Database Added Value for the Industry
0 likes168 views
NIBE is a partner in the LIFE FRONT project, which aims to help remove barriers to the use of flammable refrigerants. The project is collecting detailed leak data from the field, including failed component, leak cause, hole size, and flowrate, to build a database. This database will provide statistical insights into leak causes and flowrates. It will also help with risk assessment and mitigation measures for flammable refrigerants. The LIFE FRONT project conclusions recommend replacing flammable charge limits with charge limits based on testing. It also defines an efficient test method that could be included in standards to assess safety measures for using over 150g of flammable refrigerant indo

- 14. www.lifefront.eu 2 questions to be answered: • Which criteria to be fulfilled for a product to be deemed safe? Þ Concentration of R290 not getting > 50%LFL • What are the correct basic assumptions of leak flowrates to be taken for the test? Þ Based on database and partner experience Experimental work under LIFE FRONT project Target: • Show that adapted mitigation measures can be implemented to ensure safe usage of >150g of R290 indoor • Defined an appropriate testing method to assess product safety
- 15. www.lifefront.eu LIFE FRONT project conclusions and recommendations Recommendations: • To encourage innovation: flammable charge size limit set as of today shall be replaced by charge size limit based on test results performed on heat pump • Detailed test method is defined that could be included in the standards Conclusions: • Adapted mitigation measures can be implemented at heat pump level to ensure safe usage of more than 150g of flammable where heat pump is installed indoor • Efficient test method has been developed to assess the efficiency of the implemented safety measures
