In this video we look at how a refrigeration cycle works and use colour coding to see how the temperature and pressure changes throughout a system. We include photographs of real items so you know what to look for in the real world.
We look at the condenser, evaporator, compressor and expansion valve.

I was having a hell of a time understanding the refrigeration cycle for school and, unlike the gen ed courses I know so well from university, this is not something I could read once, take the exam, and dump it off later; I actually need to know this for the exam AND I need to retain it to be able to obtain and keep a job in my field. I’ve been trying on and off for weeks to find something that would explain it in a way that would make sense to me [online courses are new to me, so I only have reading as a way of learning, and it’s hard to retain that when I need reading and visual learning combined], but this helped. I stopped every so often to take notes, and in doing that, I feel confident that a little review here and there over the next few days will allow this to stick in my memory and I’ll never forget it. Thank you so much. I’ve liked and subscribed, and I look forward to any other videos you may have that will help me through this program.

@Glaedr11 2 года назад

Good video overall, I know it's old, was looking for videos to explain refrigerant cycle to show my trainee. I am not sure I could recommend this video, however. Just some things that could help others who see this: -being overly specific on the cold/normal/hot etc of line temperatures isnt really necessary. For all intents and purposes we call anything after the compressor and moving downstream to the metering (expansion) device high temp, and we call anything in between the metering device and moving downstream back to the compressor, low temp. -you state the line in between the evaporator and compressor as warm, but the line between the condenser and metering device as normal, when in reality the line after the evap is usually 30-40 degrees colder to the other line and would never ever be warm.

@steveistevei6103 4 года назад

hi,Thanks for your clear explanation of Refrigeraton Cycler. I have one rather important question I would like to ask. Your Airflow where does the Air come from. Is it normally a Close Loop System where the Air is constantly re-circulated by the Evaporator Fan in the Fridge, or is Fresh Air Intake going on so that the Evaporator Fan is constantly pulling Fresh Air from the Outside and blowing it through the Evaporator Coils inside the Fridge. Also if it is not a close Loop System and the Fresh Air is constantly being sucked in from outside , is it vented out as it is recirculated inside and replaced by a fresh stream of air. Thanks

@michaelblake908 4 месяца назад

When the refrigerant boils in the evaporater, that's because of the vaccum, right? Because the high side pushes and the low side pulls? Great video, by the way.

hi -I don't understand 1-for the model T2/Te2 without third pipe from thermal expansion valve-when the valve are close the orifice -the presure wrere are going ? 2 the model with three pipe -third are conected at exhaust of evaporator -when the termic valve are close the pressure are going in bypass from third pipe ? And also who close the selunoid valve and the pressure of the compressor where are going ? the baypass are after this valve many thanks where I can find a animation of this ?

@emmanuelencina8282 2 года назад

please louder the voice like other engineering mindset videos. barely hear it on outdoors with earphones but explains very well

@gooddeedsleadto7499 Год назад

Just googled it to find the answer. TXV valve or the expansion valve is situated inside the evaporating unit and the sensing bulb is also near the outlet of the evaporation unit, so the expansion or TXV valve is in the my basement before the evaporation unit and sensor after the evaporation unit? The sensor measures the compressor suction line temperature and the expansion valve release the the refrigerant mix (80% liquid and 20% vapor) based on the temperature set on the expansion valve? It ensures the super heat temperature the compressor requires to function?

@suicidesponge5269 8 лет назад

hi.how the refrigerant cycle work in a chiller?it is the same as video above?

@EngineeringMindset 8 лет назад

+suicide sponge on a simplistic level, yes it's essentially the same, although instead of a fan blowing air across the coils, a pump will push water across. I will upload a video soon for how a chiller works but in the meantime I recommend you watch our other video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1cvFlBLo4u0.html "How a Chiller, Cooling Tower and Air Handling Unit work together" as I explain the process here and include a section view through the chiller.

Location of expansion valve? Is it located in side the evaporator unit or condensing unit?

It's in the evaporator unit

@Ed-fp9rx 2 года назад

you should do your own courses.

@notnecessary7730 Год назад

Wait wait..why are you entering the condenser at the bottom??? Shouldn't it enter the top as a high temp gas, which cools and condenses to a low temp liquid as it descends (falls) through the coil? The low temp liquid then enters the bottom of the evaporator and boils off to a gas as it ascends (rises) through the coil. This direction minimizes the chance of liquid entering the compressor which would damage it. Or am I incorrect??
