Heating AC and Engine Cooling

Refrigerator was just like a air conditioner and a magnet of Tom Swayer.

Water evaporates into the air, along with other volatile substances such as alcohol, gasoline, and perfumes. Evaporation is the process by which a liquid turns into a gas due to heat energy breaking the bonds between the liquid molecules.

A certain amount of the energy carried by the cooling water, is kinetic energy, from the circulation through the cooling system. When the engine is turned off, the water stops circulating. The kinetic energy contained in the water is converted to heat, thus raising the temperature of the coolant.

Magma cools and solidifies either underground within the Earth's crust, forming intrusive igneous rocks like granite, or when it erupts onto the Earth's surface as lava and cools quickly, forming extrusive igneous rocks like basalt.

• When people breath they breath out moisture. Most air that we breath has a certain amount of moisture in it unless you are in the desert or air conditioning.
• Dry air causes our noses to dry out and become uncomfortable.
• Water needs energy to evaporate and stay as a vapour.
• These vapour particles lose energy as they strike the cold glass.
• The vapour then condenses and turns back into liquid water.
• This is really noticeable when sitting in a car on a cold day. The small air volume in the car soon becomes quite moist from people's breath and condenses on the windows.

Turbulent

Yes, there is hot air and cold air. Hot air is air that has been heated and has a higher temperature, while cold air is air that has a lower temperature. Temperature differences in the air can affect weather patterns and create variations in temperature in different regions.

It sounds like there may be an issue with the wiring or controls of your temperature switches. Check to see if the wiring is connected properly and if the controls are functioning correctly. If the issue persists, it may be best to consult a professional HVAC technician for further troubleshooting and repairs.

The degree of hot or cold is measured on a temperature scale, typically in Celsius or Fahrenheit. Hot temperatures are associated with higher numbers, while cold temperatures are associated with lower numbers.

The water in the reservoir of your car may boil out due to a few reasons such as a malfunctioning radiator cap, a leak in the cooling system, or overheating of the engine. It is important to check for any leaks, ensure proper functioning of the radiator cap, and maintain the cooling system to prevent this issue.

Possible reasons for freon not flowing into the low-pressure port during a recharge could be a blockage or restriction in the system, a malfunctioning metering device like the expansion valve, or an issue with the compressor not creating sufficient suction. It's important to diagnose the problem accurately to ensure a successful recharge.

if this vehicle is automatic,the most likely cause would be the transmission fluid cooler. it is a tank inside the radiator that cools the transmission fluid. if by any reason the tank leaks it would contaminate your water/coolant/antifreeze.

answer a cracked head will allow oil into water jacket in head, going from there thru to radiator if it was a bad head gasket, u would have water in oil instead

If the window has FROST on it you will need warm air to melt the ice. If the inside of the window has vapor on it you need DRY air. When you turn the defroster on (in most vehicles) the air conditioning compressor starts to run as well, drying out the air. The temperature should also be as warm as is comfortable for the driver. When the dried air is blown across the window, the water vapor evaporates and you can see again.

CORRECTION:

So in reality, the "pump" or compressor has no actual drying affect on the air, the compressor itself is a closed system pump, that forces gas into a compressed tube, and then upon release of the gas the tubing freezes. The a/c fan then blows outside air over the frozen tubing, which looks like a tiny little radiator, thus cooling the outside air.

During the winter, people typically do no use their a/c system (unless they live in the southwest US or someplace HOT), which basically would mean that for many months the A/C pump, tubing, condenser and other components would suffer from what's basically called "Lot Rot". Rust would build up from trapped moisture, the lubrication that keeps the pump nice and smooth would pool up and dry off the moving parts. And when the summer time hit and someone turned their A/C on it would sputter and spit and probably seize the pump. Therefore, an ingenious engineer figured out to wire the A/C system to the Defrost button, since they use very different air intakes. So you can send warm mixed air to the defrost vent, and at the same time keep the A/C system running and lubricated through the long winter months. So your A/C runs when you push defrost not to dehumidify your air, but to keep you A/C system from taking a crap in the winter.

The reason you would see an affect on fogged windows from using the A/C switch, is because it's bringing in outside cooler air, which is probably far less humid than the air you've been breathing that fogged up the window in the first place. Dry external air, whisks away the water vapor on the windows. The cooler air also has an impact on the air that was fogging the window, in that it cools the air bringing it farther away from it's condensation point and causing it to reabsorb the moisture it shed on the glass.

The defrost system, is of course by name designed to get rid of "frost", but it also uses outside air mixed with heated air to give you the same affect of removing fog. However, not only does it bring in external dry air, it also brings the temperature of the glass up, which changes the condensation capability of the air on the glass.

Take your mind back to last summer, when you had a nice cold beer on a hot day, the can sweats, water drips off the cold can because of condensation of moisture in the air on the cool can surface. Think of your cold windshield, it's probably just as cold as that beer, and the air you are exhaling and sitting in is warm and juicy, so the glass fogs up. You can either heat the glass, cool the air in the car, introduce dry air to the car, or pull over and get a beer. Basically, I would suggest that the defrost feature offers two of the 3 viable options, it heats the glass, and it brings in external warmed dry air directly onto the glass to whisk the moisture up and prevent further condensation. The A/C option only brings in cooled dry air. Which works faster? maybe A/C does or maybe not, I think it depends on how warm your engine is, since A/C can be cold in seconds, but heat takes many minutes to manifest. I think the better question is which works longer and is more comfortable, I think that's definitely the defrost.

ADDITION to CORRECTION:

The above "Correction" piece is by far the best answer I've seen on the web that bests answers the question: how to defrost/defog your car window. For what it's worth, the Correction piece is spot on about the A/C being used in the winter months as a maintenance issue. However, there is a correction (or at least some additional piece of information) to make the above answer a bit more precise.

A/C operation:

The A/C operation described above is a bit unclear. Refrigerant is compressed to around 100psi as a gas (today its r-134a) by the compressor. Then, this gas is sent to the condenser which cools the high pressure, high temperature gas into a lower temperature gas. This gas turns into a liquid by the time it leaves the condenser. This liquid (highly pressurized) is sent through tubing until just before the evaporator it is sent through a fixed orifice that quickly depressurizes the liquid and quickly turns back into a gas. That is, it evaporates. When this refrigerant evaporates, it absorbs heat; thus, we get a cold sensation. Since the boiling point of r-134a is around 35 deg f, the air around the evaporator will be about 35 deg f. As the gas evaporates in the evaporator, a blower motor blows air across the evaporator and sends this cold air (about 35 deg f) into the passenger compartment. Thus, cold air.

--

A/C as a dehumidifier:

The A/C does dry the air, but only in warm temperatures (i.e. you will see the moisture dripping from underneath your car). This moisture comes from the evaporator drain (which is inside the passenger compartment). So inside air is actually being 'dried' in the warmer months. So, the above statement about the A/C not drying the air , however, is true only if it is cold out.

--

A/C bringing in outside air:

The A/C system doesn't necessarily introduce outside air. The blower motor is inside the vehicle and blows inside air or outside air (depending on the recirculation door position) across the evaporator, then the heater core. Thus, if the A/C is on and the recirculation door is closed (closing off outside air) then no external air is introduced, and defogging doesn't occur. BUT, if your car lets you turn on defrost (which always brings in outside air) and ac, then of course, external air is introduced. So, although technical points, I add these facts. Thanks to whoever posted the above "Correction" piece as I learned a lot from it. Thanks, and I hope my little piece shed some light.

We're assuming the compressor is always running (not cycling), during this time that it's getting cool, then warm/ hot? If the compressor cycling during this time (air getting cool, then hot or warm)- you likely need to concentrate on the electrics that make the compressor run (ei, pressure switch, electric clutch, etc.) answer u need a new drier and the correct amount of gas in system checked a drier is not much to buy

It is possible that there is an issue with the blend door actuator or the heater control valve. These components control the temperature distribution between the front and rear heating systems. I recommend checking these components to see if they are functioning properly.

The boiling point of water is 212 degrees, most vehicles now days operate ftom 205 to 215. A 50% mix of distilled water and antifreeze will extend the the boiling point to 265 degrees at sea level. If you go up in elevation the boiling point will decrease, so make sure you have a known good or new radiator cap to prevent premature water boiling in higher elevations

It is not accurate or fair to generalize an entire racial group as being cool or not cool. People's personalities and traits vary regardless of their race. It's important to treat individuals as individuals and not make assumptions based on their ethnicity.

William Henry Brown (1839-1928) was an African-American artist known for his portraits, landscapes, and genre paintings. He was born in Scotland and later moved to the United States where he became a prominent figure in the art world. Brown gained recognition for his realistic and emotive depictions of everyday life, and his works are held in various museum collections.

Turn off the makeup water and electrical service to the boiler. Isolate any and all valves in the system. Thread the old tank off, thread tape and/ or thread sealant on male ends of new tank and thread it in. Bleed air from system as needed using makeup water. Dependent on the piping arangement, if the tank screws in the bottom of an air scoop, an air eliminator atop the scoop may be removed and then replaced after all air is purged. Note: in using makeup water valve/ bypass, do not go over 30# of pressure. Most residential boilers will have a safety relief valve that is set at 30# that will blow off at this pressure and make a mess. The makeup water pressure reducing valves are generaly set to maintain 12# of pressure. Most pressure tanks are precharged at the same 12# of pressure on the air side. Verify these pressures and that all air has been purged from the boiler and pumps, before refiring the boiler. lc
