The finned evaporators are most commonly used in the air conditioners of almost all types like window, split, packaged and the central air conditioning systems. In these systems the finned evaporator is popularly known as the cooling coil.

The plate surface evaporators are commonly used in the household refrigerators. These evaporators are also in the form of coil which is attached to the plate. The finned evaporators are also made of copper coil with fins on the external surface as well on the internal surface.

Evaporators of domestic refrigerator can be easily identified its location, it is located at the freezer compartment but not visible to our naked eye where ice is accumulated around its surface. Unlike the old days, evaporator is exposed.

There are three main types: air-cooled, evaporative, and water-cooled condensers.

The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.

The compressor “squeezes” the gas. It actually changes the gas refrigerant into a liquid, which is used throughout the A/C system to eventually produce cold air. The condenser is responsible for taking the pressurized gas from the compressor and changing it into a liquid vapor.

Here are four parts of the condenser unit that can lower efficiency and start costing you money in increased energy bills when they suffer maintenance problems or breakdowns.

• Condenser Coil.
• Fan Blades.
• Run Capacitor.
• Evaporator Coil.

Principle of operation A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid.

There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.

Compressor

The main components of a refrigeration system are the condenser, the compressor, the evaporator and the expansion valve.

Refrigerant lines are two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line.

If your existing line set meets manufacturer specifications for the new HVAC system, you can usually reuse it. But if it doesn’t meet those specifications, you’ll probably need a new one. You’re not replacing your HVAC system because of a refrigerant leak.

Part 1 of 3: Recovery of the old refrigerant

1. Material Needed.
2. Step 1: Hook up the AC machine.
3. Step 2: Turn the AC machine on.
4. Materials Needed.
5. Step 1: Locate the failing line.
6. Step 2: Remove the AC line.
7. Step 3: Replace the o-ring.
8. Step 4: Install the new line.

The average cost for air conditioning refrigerant line replacement is between $540 and $567. Labor costs are estimated between $105 and $132 while parts are priced at $435. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

If you see any of the following warning signs, you likely need an air conditioner repair:

1. Warm Air. When you feel warm air blowing out of your home’s vents, check the thermostat.
2. Insufficient Airflow.
3. Frequent Cycles.
4. High Humidity.
5. Water Leaks.
6. Bad Odors.
7. Unusual Noises.

For most cars, the cost of an AC recharge will be about $200 but can go as high as $280. It’s a simple procedure, but it can take a while to check everything out and ensure that there is no further damage, so expect to pay about $120 for the labor costs.

You’ve likely run low on refrigerant in your A/C system. Over time, tiny amounts of refrigerant leak from the lines, degrading A/C performance. The solution is simple – put more back in. Recharging your air conditioner yourself is inexpensive and can be completed in just a few minutes.

Four Signs Your Car’s AC Compressor Is Going Bad

1. Odd Sounds. You might hear some strange noises when you flip on your vehicle’s air conditioner and if you do, it’s probably the compressor.
2. Hot Air. The whole point of turning on your vehicle’s AC is to get cold air to come through the vents.
3. Fluid Leaks.
4. Stuck Clutch.
