What is the difference between antifreeze and refrigerant

It is also important to know that most modern combustion engines use this type of coolant system. Originally called R Freon, this form of the chemical was found to cause ozone damage, resulting in the Environmental Protection Agency outlawing it in Since then, vehicles have used the more common Ra Freon.

This piece of equipment compresses the Freon gas into a liquefied state before moving it to a condenser. Here, the hot Freon is exposed to outside air entering from the vehicle grill, cooling it before being converted into a gas. In this stage, the newly formed Freon absorbs heat within the air conditioning system, ensuring that only cool air is left behind. While coolant and Freon may serve similar purposes in that both help avoid overheating, they work in different areas of the vehicle and are thus not interchangeable.

Instead, coolant is designed to keep your engine cool and will remain in a liquid state within its system. Likewise, replacing Freon will not help to cool off your engine or other parts under the hood.

It is a liquid comprised of anti-freeze and water. It is necessary to replace the coolant from time to time to protect your engine. A refrigerant is a substance or mixture used in an air conditioning system.

It works in a cycle and undergoes phase transitions from liquid to gas and then back again based upon the pressure applied to it. These phase changes cause the refrigerant to absorb and release heat throughout the cycle. Heater Core, 6. Blower Fan. That heat is regulated in order to avoid damaging the engine.

Enter the cooling system. The cooling system is used to keep the engine from overheating. It does this by keeping the temperature at a constant so it runs more efficiently.

The cooling system uses coolant to do this. When you start your engine, a water pump circulates the coolant through the engine and radiator. Once the engine has reached a certain temperature, a thermostat opens to control the flow of coolant through the radiator. The water pump circulates hot coolant to the heater core under the dash where it provides heat for inside the passenger compartment.
