Posted in Blog. Breathing air that is contaminated with Freon can cause respiratory difficulties, organ damage and, in some cases, death. Symptoms can vary depending on the extent of the Freon exposure, but even a small amount of exposure can cause serious symptoms in humans.

Mild symptoms of Freon exposure include excitability, dizziness, changes in heart rate and headaches. The lining of the throat or nose may become irritated, and the throat may swell. Pain in any exposed mucous membranes, such as the mouth, throat or eyes, is common after exposure. These symptoms can occur within minutes. More serious symptoms can occur after prolonged exposure. Serious symptoms of breathing Freon can occur when the chemical is inhaled directly or when exposure to it lasts for more than a few moments.

Serious signs of Freon exposure include irritation of the lungs, burns on the esophagus and irritation of the stomach. Necrotic skin lesions or tissue damage may develop when the Freon comes into contact with the body.

Lung failure or death may occur with prolonged exposure to Freon. Fluid buildup in the lungs is also a common symptom.

Prolonged exposure to Freon may cause brain damage, particularly when the substance is inhaled directly. Spilled Freon should be treated as a hazardous situation, and the area should be evacuated and ventilated quickly to prevent Freon poisoning.

The refrigerant is Ra. The following system checklist shows a system with an overcharge of refrigerant values in degrees F except where otherwise indicated. Compressor discharge temperature: degrees Condenser outlet temperature: 90 degrees Evaporator outlet temperature: 15 degrees Compressor in temperature: 25 degrees Ambient temperature: 70 degrees Box temperature: 10 degrees Compressor volts: degrees Compressor amps: high Low-side evaporating pressure psig : 8.

High condenser subcooling. High condensing pressures. Higher condenser splits. Normal to high evaporator pressures. Normal superheats. High compression ratio. High discharge temperature: With an overcharged system, the high discharge temperature of degrees is caused by the high compression ratio.

Liquid backed up in the condenser will flood some of the condensing surface area, causing high head pressures. All of the heat being absorbed in the evaporator and suction line, along with motor heat and high heat of compression from the high compression ratio, has to be rejected into a smaller condenser because of backed-up liquid. High condenser subcooling: Because of the overcharge of refrigerant in the system, the condenser will have too much liquid backed up at its bottom, causing high subcooling.

Remember, any liquid in the condenser lower than the condensing temperature is considered subcooling.

You can measure this at the condenser outlet with a thermometer or thermocouple. Subtract the condensing out temperature from the condensing temperature to get the amount of liquid subcooling.

A forced-air condenser should have at least 5 degrees of liquid subcooling. However, subcooling amounts do depend on system piping configurations and liquid line static and friction pressure drops. The lower the refrigerant charge, the lower the subcooling. The higher the charge, the higher the subcooling.

High condensing pressures: Subcooled liquid backed up in the condenser will cause a reduced condensing surface area and raise condensing pressures. Now that the condensing pressures are raised, there is more of a temperature difference between the ambient and condensing temperature, causing greater heat flow to compensate for the reduced condensing surface area.

Dangers of Breathing Freon

The system will still reject heat, but at higher condensing pressure and temperature. High condenser splits: Because of the higher condensing pressures — thus higher condensing temperatures — there will be a greater temperature difference split between the ambient and condensing temperature. Normal to high evaporator pressures: Since these systems have TXV metering devices, the TXV will still try to maintain its evaporator superheat, and the evaporator pressure will be normal to slightly high, depending on the amount of overcharge.

The evaporator would have a harder time keeping up with the higher heat loads from the warming entering-air temperature.

The TXV will have a tendency to overfeed on its opening stroke due to the high head pressures, unless it is a balance port TXV. Normal evaporator superheats: The TXV will try to maintain superheat even at an excessive overcharge.

As mentioned above, the TXV may overfeed slightly during its opening strokes, but then should catch up to itself if still within its operating ranges. High compression ratios: The condenser flooded with liquid during the overcharge will run high condensing pressures. This causes high compression ratios and causes low volumetric efficiencies causing low refrigerant flow rates. Overcharged Cap Tube Systems If we are dealing with a capillary tube metering device, the same symptoms occur with the exception of the evaporator superheat.

Remember, capillary tube systems are critically charged to prevent floodback of refrigerant to the compressor during low evaporator loads.Your frostless freezer is building an igloo from the inside out.

This can be the result of a leaking door gasket. The gasket allows the cold air to constantly seep out, making the refrigerator run overtime and produce extra chill in the freezer. Check the gasket by placing a high-power flashlight or emergency battery-powered light unit in the freezer with the beam pointed at the door.

Turn the light off in the kitchen and check around the perimeter of the door. If there is any light leakage, you'll need to replace the gasket, which can be purchased directly from the manufacturer or from large-appliance retailers. There's a puddle of water under your refrigerator, and it's growing.

People don't realize that there's a shutoff valve. Typically, it's under the sink; if not, look in the basement, beneath the fridge. See if the icemaker actually got turned off by checking the wire alongside the icemaker assembly. If it's raised, the icemaker is off. Use the red lever to lower the wire, or lower the wire itself if there is no lever. You've found a puddle in the refrigerator, but all the beers still have their caps on.

The drain tube is blocked. Unplug the refrigerator and locate the drain plug near the back or bottom of the main compartment. Repeat a couple of times, then remove and clean the drain pan located underneath the refrigerator.

Your refrigerator is cycling on more frequently--and using more energy--than normal. The condenser coils underneath the refrigerator are a both a dispenser of heat and a magnet for dust--especially in homes with dirty kitchen floors or lots of pets.

Clean the coils with a vacuum. You can keep further cleanings to a minimum by cutting a section of discarded pantyhose or a piece of lightweight filter material to fit inside the vent panel beneath the door, which should prevent most debris from reaching the coils. The refrigerator is a fairly simple appliance and many small problems can be tackled by anyone with basic handyman skills.

However, the presence of in most cases, toxic coolant under pressure and the sensitivity of the system itself mean that certain situations cry out for a more experienced hand.

More From Interior Projects.There are many different causes of a refrigerator not being able to function as it should, and a variety of problems that can lead to hundreds of dollars of spoiled, ruined food.

A refrigerator normally cycles on and off in order to maintain an appropriate temperature, so many people mistakenly think that a quiet appliance has just shut off in its cycle when in fact, its compressor has stopped working.

Although a broken compressor is just one common problem with refrigerators, it can also be one of the most often overlooked, too. Pull your appliance away from the wall, and stand to listen for a few minutes and see if you hear the sound of a motor running, or a soft humming.

If you do hear a humming noise, but the food in your fridge is warm, your compressor may be functioning improperly or it may be a different issue causing the problem altogether. When a compressor is bad, the repairs can cost more than what a new appliance would. Posted By: Erin White Categories: beer caves. Email This Post.

We will get through this together. Updated: December 11, References. Adding Freon to a refrigerator is a tough task. Freon is also toxic and can cause a variety of health problems if you ingest it.

How to Know When a Refrigerator Needs More Freon

Check the vents on the back and inside of your freezer, and see if you need to defrost any frozen coils. Fix any leaking pipes by replacing or soldering them. Then, install a bullet-piercing valve and check the Freon by using a specialized gauge before adding the Freon. Tip: CFC stands for chlorofluorocarbon. This is the scientific name for Freon. If your fridge runs on CFC, it uses Freon.

Warning: The valve must be completely tight on the pipe. Consult a repair specialist if you accidentally damage the valve or install it incorrectly.

This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness.Being able to add Freon to your refrigerator compressor requires expertise because of the health and safety risks involved. This is because Freon is a toxic substance that may cause serious health issues if it is not handled properly.

More so, if you mistakenly add too much Freon or use the wrong type of Freon, you may have to deal with an irreversible damage. Nonetheless, this article provides a stepwise guide on how to add freon to your refrigerator compressor. However, because of the risks involved in this process, we are hoping that if you are not a technical person, you only need this information for the knowledge.

If you have perishable foods in the fridge, transfer them into a cooler filled with ice to keep them fresh. Because it is not unlikely that there are other pipes connected to the compressor tank other than the Freon pipe, you want to avoid feeding the wrong pipe with Freon.

How to Check AC Freon Level

On some refrigerators, the Freon line has its own pipe while in others, it is attached to the suction line. So, it is important that you check the manual for the right configuration. Then, wrap this valve around the Freon line, near the compressor. This valve will help you access the pipe without removing it by puncturing it.

Most importantly, ensure this valve is tightened around the Freon pipe. Else, it might leak Freon and air which will be dangerous to your health. To access the pipe easily, unscrew this cap by turning it counterclockwise. You can do this with your hands. Then, wait for about seconds before attaching the air compressor gauge to the adaptor. An appropriate reading is important to know if you should add Freon or not.

This implies that there is no pressure in your Freon line. But if it is higher than 1 psi, open the valve for about 4 to 10 seconds to let out some air. Then, check for the pressure again. This can be done by checking the label inside or at the back of your refrigerator. If the reading you got from your gauge falls within the Freon range on the guide, then the problem may be more complicated than adding freon to your compressor.

Connect this tank to the hose and then connect the hose to an adaptor on the valve attached to the Freon pipe. After transferring Freon to the Freon line attached to your compressor, turn the valve on the replacement tank clockwise.

Older fridges in general use more electricity than the newer models. And when a fridge stops working, it will use more electricity as it struggles to maintain a cool temperature despite a malfunctioning compressor, a tired motor and leaky seals.

Families that replace their old refrigerators notice immediate savings on their energy bills. The main function of a fridge is to keep food cold.

This task is accomplished with the help of a condenser, evaporator, fans, timers and thermostats. These components all use electricity, especially the motors. The fridge is heavily insulated to retain the cold generated by the appliance, and gaskets between the door and the fridge housing keep cold air from leaking out. The gaskets between the door and the housing can deteriorate over time. The adhesive holding them in place may wear out, or the rubber itself can lose its elasticity.

As the door gaskets fail, the fridge loses cool air and has to work harder, drawing more electricity in the process.

The temperature of the fridge, especially on older models, is controlled by the fresh food thermostat. The fridge thermostat is basically a switch that is normally open. It closes when the temperature gets too high, causing cooler air to be forced into the freezer and fridge by a fan. The thermostat can fail and stick in the closed position. This means the fan is constantly pushing cool air into the fridge compartment, working harder than normal and drawing considerably more energy.

The compressor is part of a system of components that create cold air for the refrigerator. It connects to heat-exchanging pipe coils outside the fridge. At the end of that pipe system is an expansion valve that allows refrigerant to exit as a fine mist.

Can a Refrigerator That Is Going Bad Use More Electricity?

Another set of heat-exchanging pipes wind through the inner wall of the fridge. If the coils or expansion valve become blocked, the compressor will run constantly and use excessive energy, even though no cool air will reach the refrigerator compartment. If the compressor fails, it must be replaced or you need to buy a new refrigerator.

Many post refrigerator models have complicated systems for monitoring temperature and controlling cold air distribution.
