How Dirty Oil Damages An Engine

Living in warmer climates with a car that does not have a functional AC unit is some kind of personal torture. Sure there might not be a need for it during errands in the city, but that’s only one portion of overall time. A lot of driving time is spent commuting from point A to point B, whether it be from home to work, picking up kids from school, or any kind of social activity outside the neighbourhood. During these driving excursions it’s imperative to have a strong AC unit in the car.

What if, however, it begins to become less and less effective. The first thing to be done is read up on how the AC unit of a car works so that the depths of the issue can be understood. If it’s getting serious, most garages in Longmont that do oil changes will also be able to check the functionality of the AC unit.

The Basics Of Air Conditioning



The basics of air conditioning revolve around two general processes: evaporation and condensation, on one hand, followed by compression and expansion. These are the general processes, but they do not explain the mechanical components that make it happen. What are the mechanical components? They are the compressor, condenser, receiver-drier, expansion valve, and evaporator. This pieces are all connected by hard tubing in the intestines of the car to ensure that cold air is blown out of the vents in the sitting area. The fluid that passes through these tubes is a refrigerant that can evaporate at a low temperature and condense at a high temperature. But what do each of the mechanical components do?

Compressor - The functional basis of the whole system is the compressor, which is connected to a drive belt and sends high pressure refrigerant where it needs to go - the condenser.

Condensor - The condensor does exactly what it sounds like it does. It’s read more role is to change the refrigerant from a high pressure vapor into a liquid. High pressure is the major causal force that turns the vapor into fluid. This high pressure produced a lot of heat, which, once effectively utilized, is siphoned out of the condenser by simple air flow.

Receiver - The liquid then moves on to the receiver/dryer, where any moisture is removed.

Expansion Valve - Now the most exciting part of the trip: the expansion of the liquid into vapor once again. The expansion valve actually removes all the pressure on the liquid that was otherwise holding it down. This allows it to expand into vapor once again.

Evaporator - The evaporator is a small device that has hot and cold air passing over it at all times - that is why AC units cycle air around the car. At this point the cyclical design makes it such that hot and cold air interacts and is pushed into sections of the car where the driver wants them. It’s also the evaporators role to do away with condensation that collects during the process.
