What are the different roles of refrigerants in an HVAC system?

Every HVAC system operates on specific principles.

  • Refrigerants are used in most of these systems.

An HVAC system’s refrigerant plays a crucial role in the system’s operations. These roles help in the heating and cooling of your indoor space. Without the right refrigerant amount, your air conditioning system will not do its job. The refrigerant in your HVAC system combines various heat transfer fluids used in all heat pumps and air conditioning systems. Your HVAC refrigerant runs between the air conditioning system, the outdoor unit, and the indoor unit. The function of the evaporator coil inside your AC unit is to evaporate the refrigerant for it to absorb heat from your indoor space. A heat pump reverses this process to draw heat from outside during winter. After the refrigerant absorbs heat, it is sent down through the refrigerant line to the condenser coil, where it condenses back into liquid form. Heat will then be released either into or out of your home, depending on your heating or cooling needs, helping your air conditioning system function effectively. The refrigerant cycle keeps running until your desired temperature is achieved by moving cold air indoors and pushing hot air outdoors through the refrigerant piping. When refrigerant is infused with copper, it plays an integral part in the absorption of heat flowing through different copper components, typically known for being good heat transfer conductors. Refrigerant is the USP of HVAC systems, which should not be overlooked. It has made it possible for people to survive extreme weather conditions all around the world.
