what are Flue Gases in an Air Conditioning System?

Flue gases are gases emitted from combustion. These are usually the reaction products that result after combustion. A portable flue gas analyzer is used to detect and observe the composition level of the flue gas to determine if the mixture of air and fuel is at the right ratio for maximum heat output.

Learning that, let's move on to understanding flue gases and air conditioner's relation.

Flue gases in air conditioners

In an air conditioning unit, a fan draws the air in and forces it over the evaporator's coils to cool air. Filled with refrigerant, these coils draw heat from the air, cooling it.

Further, the air moves into the air handler, where a blower sends it into the ducts. As the cool air moves through the ducts, any noxious gasses produced during the process are expelled through the flue. These are the flue gases.

When an air conditioner absorbs heat, the refrigerant vaporizes. To return to its natural state, the refrigerant travels into the compressor, which pressurizes it, and onto the condenser, where it condenses from a vapor back into a liquid. As it does, it expels heat blown out by a fan.

What happens to cooking oil after it's been heated?

Image
  Image Source: https://www.testo.com/en-IN/ When cooking oil is heated it will start separating before bubbling, and at extreme heat, levels will give out smoke. But they won’t undergo any chemical change until you drop food items in it for deep frying or sautéing etc. When you deep fry food, it is basically a dehydration process. The water & water-soluble substances get extracted from the food and transferred to the cooking oil. Cooking oils undergo chemical changes including oxidation of the fatty acids, polymerization of the fatty acids, and breaking apart of the triglyceride molecules into free fatty acids and glycerol by hydrolysis, which will further increase with cooking time and temperature and are accelerated by the presence of food. Various degradation substances are produced in the oil due to these actions called total polar materials(TPM). Repetitive heating contaminates the oil and harms your health adversely. You should use a digital cooking oil tester ...

How do digital thermometers show temperature without mercury

Image
D igital thermometers are best known for their faster results than mercury thermometers, which take time to show readings as you have to wait for the mercury to heat and then slowly rise to display the temperature. Digital thermometers use metal components and advanced technology to provide quick results. Metal has natural heat resistance. It is a temperature measuring device that uses an electronic circuit . It works similar to other thermometers, wherein the captured information is sent to a microchip that processes it and displays the reading in numerical form on the digital display screen.

What are the Advantages of Using GPS Systems?

Image
Global positioning system (GPS) is a satellite navigation system that uses satellites to locate any object accurately.  GPS system helps with tracking and locating any object, person or any other movable thing, which you might want to keep track of. The system helps keep a track of the vehicle on a travel. It is extremely helpful in accident cases, or any missing investigations. It keeps a check on the driver and reduces the risk of nay kind of misuse of the vehicle It is extremely easy to navigate because it shows the direction during a journey to reach the destination. GPS works great with all kinds of weather conditions which may not be the condition for other navigating devices. GPS is the most cost-effective systems of all the other navigation systems.
