Hi Guys, as always a big fan of you guys... Great video there.... lot more packed in 8 minutes... Just an humble suggestion, a small introduction of compression/expansion effect on temperature (blowing a baloon, or just simply blowing cold air through mouth) would have probably been a perfect start, i guess... Anyways, great effort guys.

If you're wondering WHY the pressure drops when it goes through throttling device, it is due to the Bernoulli effect. A key property of this effect is that as velocity increases, pressure actually decreases (contrary to common expectation). So, as the liquid flows from a large diameter into a smaller one, the flow velocity increases and thus the pressure decreases.

@gelomelo3426
@gelomelo3426 2 жыл бұрын
When the liquid leaves throttle and liquid goes towar evaporator, it's (-20 Celsius), it absorbs heat, so the new temperature has to be increased, ( - 15), because it has absorbed heat, and when the liquid leaves the evaporator in gas phase, it is still (-15), and when you contact liquid phase line (-20 c) and gas phase line (-15 c), how evaporator out put line makes evaporator input line cooler, when is has much more temperature??

@@gelomelo3426 Refrigerant in the evaporator does not experience a rise in temperature, only a phase change, which requires energy. That's why it's called the evaporator. The heat absorbed from the air inside the fridge drives a phase change and evaporates the remaining liquid portion of the refrigerant fluid. He says the temperature of the fluid in the capillary tube is brought down significantly because only the very end of the capillary tube has the same temperature as the fluid in the evaporator. At 5:10 you can see the temperature gradient along the capillary tube while it's coiled. That gradient still exists when it's straightened. So if you run the evaporator exit line along the capillary tube, they have the same temperature when they first meet near the evaporator. But as you go farther down, the temperature is higher in the capillary tube. So there is heat exchange between the two lines, and the effect is cooling the capillary tube. Top line is the capillary tube exiting the compressor, bottom line is the evaporator exit line [compressor] ------->(45*C, high pressure liquid)------->(somewhere in between)------->(-20*C, liquid and gas)--->[evaporator]

"The throttling device is an obstruction to the flow, so a huge pressure drop occurs..." You should elaborate on this because 1. It is the essence of why it works. 2. The way you say it is counter intuitive. Why would liquid lose pressure when pushed through a smaller space?! The point here is that the same amount of liquid has to pass through a smaller diameter in the same time so the speed at which the liquid passes a given point is higher. According to Bernouilli's principle a fluid/gas that moves faster has lower pressure and vice versa. This is also what makes a plane fly.

This seems fully comprehensible only by physicists or engineers, but I did get a little from it.

I also know why my new fridge is almost totally quiet.

aullik Piston compressors are outdated technology! They are energy inefficient and noisy. Think of a car engine (pistons) vs electric motor. Most noise and energy loss in a compressor is caused by the piston(s). By removing the piston, it will be much more efficient and quieter. This is why rotary compressors (screw, centrifugal, etc.) are much better.

As a rule high concentrations of energy always diffuse to lower concentrations. That goes for temperature, pressure, and many other things. So think of it less as cold penetrating the items in your freezer, but the items losing their energy to the less energetic surroundings. Of course all the energy has to go somewhere, which is what the condenser is for, radiating it outside the freezer.

good video for beginners but for those with a little more awareness, those folks may pick up that the numbers were a little off: a pressure-temperature chart (pt chart) for R134a has 45deg C (113degF) is 153psi which is 10.5 bar, not 8. My point here is not to be a stickler on the video makers but to let folks know who watch these videos that if you know the temp, you know the pressure due to the pt chart. google pt charts of a specific fluid. they're everywhere. also know that pt charts, volume is held constant. pt charts used to confuse me, so I'll share this which took me forever to understand: say you have pt chart of water. the pt chart will reflect at psig 0 (i.e. atmospheric pressure) the temp will be...what? 212 deg F. Increase the pressure, increase the temp, decrease the pressure, decrease the temp. Why? Think of cooking mac and cheese in the mountains: you boil the noodles longer because water boils at slightly lower temp because atmospheric pressure is slightly less. So, lower pressure = lower temp. This is true for every substance/fluid.

Here's a tip on saving electricity - The more stuff you have in your refrigerator, the less electricity it will use, to a point, of course. When you open the door, all that cold air rushes out and warm air rushes in. Then the refrigerator has to work to cool that warm air. You could, for example, fill your refrigerator with empty milk cartons or gallon jugs of water. Then, when you open the door, there is less air to rush out. In the East Asian countries, many families have small refrigerators. When Chinese, Japanese, and South Korean students visit America, they are surprised to see such HUGE refrigerators! What army are you feeding that you need so much food on hand all the time? This partly explains the obesity crisis. Most Americans think it's normal to eat huge meals, filled with sugar and starch, and to eat snacks during the day as well.

The amount of warm air let in, takes very little power to make it cold. The 'weight' of that air is tiny, compared to the weight of a bag of peas etc. A bigger problem is the moisture in that new air. It becomes ice. So everytime you let new air in, you cause more ice to build up in the freezer...

But how does the throttling device decreases the pressure and hence the temperature?

+chetan raina Thnx for the tip, I just did... Could you tell me if I could put it this way: I see "gas pressure" as how much the gas molecules hit each other and the walls of the container, so when the molecules pass through the throttle not all of them succeed in passing, so we have less molecules on the other side of the throttle, so the pressure decreases on that side because less molecules are hitting each other... And because the pressure drops the temperature drops by charles and boyle's laws. Sorry for deforming physics XD
@cr-ic3qv
@cr-ic3qv 7 жыл бұрын
No Signal yes you're right. This is the reason that the throttle is thinner than the container tube. When the coolant goes from that thin capillary tube to the container with much wider walls it is spreading to a larger area. Increase in area means less pressure because collisions will decrease as area increases.

Good afternoon! I just bought a Starlight minibar fridge and am very interested in this part! Because every 3-5 minutes the circulation turns on for 1-2 minutes. The refrigerator cools normally and the compressor does its job too! That is, I hope because you have your own voice added to it during and as you showed it warms up while you work. I hope my new refrigerator works well in my bedroom. Next to it is 5 cm and behind it 23 cm space for ventilation and was placed in the cold part of the room.

Instead of the expansion valve there is the throttling device ("solenoid winding"). How does this device decrease the pressure?
@northernstar450
@northernstar450 5 жыл бұрын
because pressure is directly proportional to temperature according to the formula PV=MRT as pressure rises by being forced through the capillary tube its temperature rises soon after the capillary tube it expands and takes energy from the surroundings cooling it

@@manfredinotarangelo5525 temperature rises as a consequence of energy input, think of it like you pump up the tire of your bike, at the valve the tube is boiling hot soon after the valve the gas expands and therefore it cools down (just like the white jet streams you see in the sky, after a compression the expansion side is cold in the jet engine that is condensing the little water droplets and you see them as white lines in the sky, in the refrigerator the capillary tube due to internal friction and smaller diametre the gas by compression gets liquefied. at the entrance to the freezer I believe the pipework gets wider and that releases the high pressurized liquid to a low pressure (think of it after a traffic jam the road suddenly widens up to 10 lanes ) so the expansion takes away energy from the surroundings and that causes cooling the surroundings - thats the freezer area of the fridge. in the end by taking the energy from the sorroundings our gorgeous gas becomes liquid (i the black condensor grill behind the frindge and goes back to the compressor, and the cycle continues

@@northernstar450 The decrease in pressure causes a decrease in temperature. this is obvious. the decrease in pressure cannot be guaranteed solely by internal frictions because the tube that connects the gas tank in a high pressure liquid state with the evaporator is very short, therefore the pressure drops will be very small.
