Refrigerants are fluids that are used in refrigeration cycles and heat pumps. Most of the time, a refrigerant will undergo a transition from liquid form to gas back and forth. The main criteria that a refrigerant has to meet is safe usage, flammable-free and toxic-free properties. Most refrigerants nowadays are especially designed to avoid causing […]
