<\/iframe><\/p>\nCharacteristic<\/p>\n\u2022\u00a0Environmental friendliness: R32 refrigerant has a lower Global Warming Potential (GWP) and is more environmentally firiendly compared to traditional R410A refrigerants. \n\u2022\u00a0Energy efficiency ratio: R32 refrigerant has a high energy efficiency ratio, which can provide better refrigeration effect while reducing energy consumption by 1. \n\u2022\u00a0Flammability: R32 has a certain degree of flammability, so special attention should be paidto safety measures during installation and maintenance.<\/p>\nSpecification<\/strong><\/p>\n<table border=\"1\" width=\"100%\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td align=\"center\" valign=\"middle\" width=\"140\"
