Who is the inventor of the modern refrigerator?
carl von linde John Gorrie. His basic principle is often used in refrigeration today such as cooling caused by the rapid expansion of gases.
What are some disadvantanges of refrigeration?
Freezer burn? BoNgWiZarD: Refrigeration uses specialised equipment (which can be quite expensive in some countries) and can use a rather substantial amount of energy. Also, the refrigerants can be somewhat harmful to the environment (modern gases contribute to mainly to the greenhouse effect and not ozone depletion as did older refrigerants)
Do gases contain unbalanced numbers of electrons and protons?
Neutral gases do not; ionized gases do.
What is A Grade 8 Science Experiment powered by liquids or gases?
Gases.
Do gases keep their shape?
Gases can NOT change shape because gases don't have a 'shape', it's the container in which they are held that has a shape)
What is the purpose of air ejector?
To remove air and noncondensable gases from a main steam condenser
Is noncondensable gas the as inert gas?
No, also the so called inert gases can be obtained in liquid form. Inert had a chemical sense, especially in the past.
What is the purpose of a steam trap?
The purpose of a steam trap is discharging noncondensable and condensable gases. They are essentially automatic valves that discharge using a small amount of live steam.
Why throttle valve is used instead of expansion cylinder in vapour compression refrigeration system?
In vcrs system there is a phase conversion system i.e. liquid state to gases state and this happens with latent heat of working medium but on the other hand there is only gases expansion on expander cylinder and no phase changes occurs and in cylinder we can not expend two phase system..
Application of compressibility requiring liquid and gases?
Vehicle breaks hydraulic mechanism , refrigeration
Why are capillary blood gases less desirable than arterial blood gases?
skin puncture blood is only partly
What is the purpose of trap in operating system?
The purpose of a steam trap is discharging noncondensable and condensable gases. They are essentially automatic valves that discharge using a small amount of live steam.

Why is the line to the refrigerant cylinder purged after evacuation and before charging?
When it comes to HVAC systems, purging the line to the refrigerant cylinder is an important step in the refrigeration process. This is done after evacuation, and before charging, to ensure that the system is properly charged and functioning correctly. The purpose of purging is to remove any non-condensable gases that are present in the system. Non-condensable gases can be any gas that is not part of the refrigerant and can cause many problems in the system. These gases can cause the system to be inefficient, as they can reduce the overall efficiency and cause the system to be less effective. Non-condensable gases can also cause the system to operate at higher pressures, and this can lead to damage to the system. By purging the line to the refrigerant cylinder, any non-condensable gases are removed from the system. This allows for the system to be charged with the correct amount of refrigerant and operate at the proper pressures. Without the non-condensable gases, the system will be able to operate more efficiently and effectively. Another important reason to purge the line to the refrigerant cylinder is to ensure that the system is not overcharged. If the system is overcharged, it can cause a variety of problems. Overcharging can cause the system to become overly pressurized, and this can lead to component failure. It can also cause the system to be inefficient, as the system will be unable to cool properly. By purging any excess refrigerant prior to charging, it ensures that the system is not overcharged and will operate at the proper pressures. Overall, purging the line to the refrigerant cylinder is an important step in the refrigeration process. It ensures that the system is properly charged and functioning correctly, and it also helps to prevent overcharging and component failure.

Which atoms in the CFC molecule can destroy thousands of ozone molecules in upper atmosphere?
The CFC molecules are man made chemicals for refrigeration. The molecules on reaction release 2 gases. These gases are Chlorine and Fluorine.
What is the difference between air conditioning and refrigeration?
'One stores food and the other keeps your house cool!
