Scientists have been looking at eco-friendly refrigerants for home air conditioners. They're trying to find ones with a low impact on global warming. Currently used refrigerants can harm the environment. To solve this, researchers are working on newer options. They want to swap harmful refrigerants with better ones in heating and cooling systems. They are studying blends of different chemicals to achieve this. These blends can work well in heat pumps used at home. Some blends are great replacements for current refrigerants like R410A. Researchers are also looking into how safe and effective these new refrigerants are. The goal is to find alternatives that are eco-friendly and don't harm the ozone layer.
