What happens in between evaporation and condensation?
Compression is the most important stage happening in a VCC. We know that heat can not pass from low temperature to high temperature. Due to compression Boiling Point of a refrigerant increases above either ambinet temperature or above cooling water temperature and also refrigerant temperature is very high than abmient. Hence heat can flow from refrigerant to atmosphere. This allows sensible cooling first and below BP further high amount of latent heat is removed causing liquification of refrigerant which is not possible unless pressure is raised after evaporator. Hence Compressor is required.
Why is biomechanics important?
Biomechanics is important because it is in different organs in parts of your body.
Can friction be important?
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.
When did albert Einstein invent the refrigerator and how?
Yes, Einstein did invent a refrigerator. He only designed one. He did not invent the FIRST one.Einstein did however invent the FIRST refrigerator having no moving parts and thus requiring no seals, which might develop leaks. This was very important at the time, as all available refrigerants were either toxic or flammable and refrigerator leaks were killing people!However his invention became irrelevant just a few years later when the safe freon refrigerants were invented. The only place where it ultimately saw use was in the liquid metal cooling systems of certain types of nuclear reactors, where the sodium and potassium metal coolants used react violently on contact with either water or air.
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
What is a refrigerant label placed on?
Refrigerant labels are placed on medications, vaccines, specimens and other things that require them to be refrigerated. It is important that they be placed in the refrigerator so that they will stay safe.A refrigerant label is placed on cylinders and containers where refrigerants are stored.
It is important not to mix R-22 and R-410A refrigerants in the same container because?
They operate at different pressures and mixing them will cause cross contamination plus it will damage the a/c system.............
How do you add refrigerant to compressor?
Adding refrigerant to a compressor is a precise job to take on, and it is important to know exactly what you are doing. Attaching the Freon kit, turn on the compressor, and adding the refrigerant are the steps to adding refrigerant to a compressor.
Why ethane is an important industrial chemical?
Ethane applications are: - precursor in ethylene preparation (the most important use) - refrigerant - fuel
How do you add Freon to your central air conditioner unit?
Adding Freon to your AC UnitAlthough, some of what I've read here is right on, I feel it necessary to state that you should utilize an EPA certified person.Charging an ACsystem is more complicated than you may think. Superheat, subcooling...Still with me?... Oh, and yes, length of your refrigerant line-set...Did you know you need 0.6 oz of freon, puron, r-407c or what whatever else per foot?It is important to DO YOUR RESEARCH or you soon be will be calling for a professional!It is illegal - on a Federal level - to attempt to do this yourself unless you happen to be an EPA certified technician. Hire a professional. [From HVAC-Talk and Environmental Protection Agency]That's right, and dangerous too! Call a reputable pro.It's not "illegal " to top off your ac, but you must be certified if only to purchase the freon. Before you attempt it, it's good to read up on it or take a class. It can be dangerous and you could damage your unit if specific procedure are not followed.NOTE - Never, an air conditioner is a closed system. If you need to add refrigerant you have a leak that needs to be repaired!In theory you should never have to add freon but there can be some residual loss. Maybe after five to ten years?This is not a simple question. Regardless of the fact that you should be a certified technician to purchase R-12 and the other legalities and environmental concerns involved, if your system was properly installed, it should not need additional refrigerant. If the refrigerant level is low, then refrigerant has escaped from the system through a leak that should be repaired before additional refrigerant is added. Leak checking and repair requires specialized equipment and skills as does measuring refrigerant charges, recovering refrigerant, determining the correct charge, and adding the refrigerant. There is the possibility of injury or death from contact with escaping refrigerant or high voltages inside the unit. There is also the large liklihood of damage to your system from over charging the unit.Many people automatically assume that because their system is not cooling to their expectations, it must need more "freon". Believe it or not, the refrigerant charge is usually not the cause of the problem. There are many, many things that can affect the ability of an A/C system to cool properly. These may include the capacity of the system, the cleanliness of the components, the integrity of the duct work, the personal habits of the users of the system, the weather (heat and humidity), the condition of filters, and the proper functioning of the various components of the system. There are many things a layman can do to improve the performance of an A/C system that do not involve adding refrigerant. These are very important first steps that can be completed prior to calling a qualified service technician. This maintenance will often solve cooling problems and will always reduce the cost of a visit from a service tech. There are many resources on the web that will outline how to perform basic maintenance on your A/C unit. If, after performing basic maintenance and cleaning, you still feel that your refrigerant charge is low, then it is time to place a call to the service tech.** Choosing a technician is an important step. Many people so not trust service personnel. While there are certainly dishonest people out there, most technicians are competent and honest. The problem is that many service technicians do not do a good job of communicating with the customer before, during, and after servicing the unit. This lack of communication fosters mistrust with the customer. Techs often do not like to answer questions which is poor business practice. Communication will keep customers loyal and increase business. Techs -- learn to appreciate your customer's questions and take the time to answer their concerns in detail -- you will be amazed at the good response you will receive!!!The best advice for cooling problems is: Educate yourself (learn how maintain your unit) Perform regular preventive maintenance (within your capabilities) Locate a competent service person whom you trust and listen to them.Finally, for the hardcore amongst us, Get certified and spend your money on proper equipment. In doing so, you will be required to learn and demonstrate the knowledge required to perform service, purchase refrigerant, and make decisions on how to repair your system. In addition, you will know why "adding freon" is not always the answer.Since Nov. 14, 1994 the EPA has required technicians who work on any appliance that uses refrigerant to be certified under rule 608 and 609. In addition only certified technicians can purchase refrigerants. Retail and wholesale outlets that sell refrigerants to the general public can be fined and criminal charges can be filed against them. There are three levels of certification depending on the type of work the technician performs and there is a separate certification for automotive repair. For those that want more information try www.epatest.com for free downloads and online certification.The process of adding or deleting refrigerants from a system are controlled by law and the procedures for which are specified by law. Even if these laws were not in place, the process can be dangerous. No two refrigerants are the same and no two refrigerants are designed to be mixed. Improperly mixed refrigerants can be explosive and can become poisonous gases. Since Nov. 15, 1995 it has been illegal to vent any refrigerant including sustitutes for CFC's, HCFC's and HFC's. All refrigerants must be recovered and either reclaimed or destroyed by a licensed reclamation center.In Ontario, you must have a valid ODP card to purchase refrigerant. The only reason that you would EVER have to add refrigerant is if there is a leak. The leak MUST be repaired first - so call a professional!The handling and use of refrigerants are regulated by the EPA, and require certification to obtain or use. A qualified technician will need to purchase and install refrigerant ( Freon).Please read this thread; How do you add Freon to your central air conditioner unit

Comprehensive care involves teaching patients to care for themselves.
When soldering a replacement fitting in a refrigeration circuit it is important that?
You take into consideration the type of refrigerant used in the system.
My 1998 Chevrolet Malibu LS AC system is warm how much refrigerant does it hold?
You have asked a very important question. The answer is just how do you intend to measure the refrigerant. On the R134A systems the answer is EXACT. There is no room for guessing. To much is worse than to little.
Why is change of state important to air conditioning?
The refrigerant change of state is what causes the heat transfer. The refrigerant is a low-pressure liquid when it's in the evaporator, which absorbs heat from the air, cooling it. The absorption of the heat causes the refrigerant to boil (change state from liquid to gas). The gas is then brought to the condenser in the front of the car where it cools (rejects heat out) and condenses back to a liquid.
How much freon for 2007 peterbuilt?
Well, it's only Freon if it was manufactured by DuPont and sold under that name - Freon is a trademark of A.I. DuPont Corp. and applied to a line of CFC and HFC refrigerants manufactured by them.But, on to what's important... a 2007 Peterbilt WHAT??? You have to understand that Peterbilt manufactured (and continues to manufacture) trucks from Class 5 to Class 8, and refrigerant capacities will vary between, say, a Peterbilt 330 day cab and a Peterbilt 379 with a sleeper berth and dual AC systems.

What is the function of the compressor air conditioning?
Well, like the name implies, it compresses. It creates the pressure by which the refrigerant (and also the compressor oil) flows through the AC system. Refrigerant enters the compressor as a low pressure vapor, and is compressed into a high pressure vapor. In the process, this heats up the refrigerant, which is important as air conditioning works through a heat exchange. This high pressure vapor travels to the condenser, where the heat which has been absorbed by the refrigerant is exchanged rapidly to the ambient air through the fins in the condenser.
