Walk In Freezer is Slow To Cool

[@CapsCup2012]

These are some of the best videos you can find. Very efficient, and nobody really covers pressures and what they should be like you do. I’ve learned a lot and continue to watch your videos. Thank you!

[@dukerivas]

Your channel is awesome, been doing commercial kitchen appliances for 13 years and would have been awesome to have a channel like yours with real techs out on the field teaching and sharing their findings specially rational combi’s , keep it up brotha 👍💪💯

[@REFRIGERATIONKITCHENEQTECH]

Thanks!

[@David.rivas.alexis]

I’m gonna to be learning from you videos on a whole new level because soon I’ll be working for a company that includes Hot side work 🙏🏼

[@REFRIGERATIONKITCHENEQTECH]

Hot side is tough because there is soooo much equipment. But it all really falls down to schematics and sequence of operations. If you can master the two of them you will be very successful.

[@davejohnsonnola1536]

Great use of emphasizing Dick Wirz and use of saturation temps regardless of refrigerants or pressures. Had the pleasure of meeting him at Bryan Orr's first symposium in 2020. Your use and explanation of the stress test is not something I've seen much of and applaud. Kudos! Davejohnsonnola

[@pnp8849]

I'm surprised you use 10-15TD and 15CS on a walk-in freezer. I'm using 5-10TD/20CS and it better match to your gauge. But I'm glad you calculated using your number to show different variation. I've been reading many books and watch your videos in the last few months. I now understand everything you taught on your videos, supper cool!!! I wished you could do SH. You should've set up donation box I would pay since you made me lots of money too.

[@germangrajales1335]

You are the best my friend,I love your videos,very good explanation,

[@Millyy766]

You do explain very well my friend , congratulations on your work , amazing 🙌💯

[@musakavalci9470]

Another excellent video. Great explanation and easy to follow. 👍🏼

[@REFRIGERATIONKITCHENEQTECH]

👍👊

[@adamw.4222]

Can you show next time how you charge the commercial fridge or freezer? Where you connect the hoses on low side and high side and how you charge the freon

[@sengle9831]

Thank for spent time to record and explain all detail I learn a lot form all your video

[@REFRIGERATIONKITCHENEQTECH]

Thanks!

[@jerryfrigeration]

I'm really enjoying your channel. Thanks

[@refrigerationconfidential4376]

Great video... nice leak find 👍🏽

[@jousemartinez1678]

appreciate the video, i have a question on why you add 15 and not 30 for ambient

[@lifeproject9182]

I been looking for a video with this info . Thanks

[@neilvestervictor180]

great professional work

[@harrydickson4575]

Excellent job 👍👍

[@Techniclay]

I've found great value in your videos. if it's not too much to ask I know your time is valuable but I have a question. Do you always use 30deg for the condenser? and doing the math for the evap you said depends how the TXV is set up. Can you elaborate? do you mean what the superheat is set to? THANKS !

[@Techniclay]

nevermind looks like you have answered that question in Nausium thanks again

[@REFRIGERATIONKITCHENEQTECH]

Newer equipment is using a 15TD Condensor. Generally for walk in freezers we want 6-10F SH, but we can use 10F as a ball park for troubleshooting. If the installer set the SH to 6F the td would be 6F

[@jfs520]

Phenomenal video thank you for sharing

[@donnieboy123]

My grandma’s 25 yr old fridge is still running well that only needs a door seal and my 4 yrs whirlpool is @ a recycle yard. Mostly junks out there.

[@REFRIGERATIONKITCHENEQTECH]

🤣

[@delanof8501]

Great work. Any specific book you'd recommend for learning about commercial refrigeration? Thank you.

[@REFRIGERATIONKITCHENEQTECH]

I bought a book over 10 years ago called refrigeration for A/c techs by Dick Wirz and it is still in my glove box to this day.

[@delanof8501]

Perfect because I ordered one 2 days ago but wanted to see what you would recommend. Guess I made the right pick. Thank you.

[@germanbadillo5278]

How do you when to use the 30 above ambient at condenser or 15 whether it’s a reach in or walk in Thanks

[@samersarah957]

You’re doing the job in good, but with using formula it’s better. Thanks

[@REFRIGERATIONKITCHENEQTECH]

You are welcome!

[@shine-cg9uf]

Love the Way u operate. Question on CS, I thought condenser splits wer around 25 for freezers n 30 for coolers. U had 15 ? Thanks again for sharing!

[@REFRIGERATIONKITCHENEQTECH]

The older condensing units used a 30F condenser split. A lot of the newer units including the reach in units are now using a 15F split.

[@shine-cg9uf]

@@REFRIGERATIONKITCHENEQTECH thanks for the information. Great video n and thanks for sharing 👍

[@pnp8849]

@@REFRIGERATIONKITCHENEQTECH From what I read the manufacturers are now using multiple CS based on compressor hp. It's now hard to know exact CS w/o oem spec sheet. I was hoping you did SH or SC at condenser. It would've been a perfect top notch video.

[@raviyadav8743]

So informative video , Can you send me formula how to find out correct charge in system

[@REFRIGERATIONKITCHENEQTECH]

Use the sight glass, if no sight glass, head pressure would be used

[@kirktrapp7001]

Ok watched video noticed that you used saturation temp for suction pressure spec now at -10F box temp wouldn't your coil be more at-20F at 10 degree T.D. and at 10F superheat wouldn't that put your final suction pressure on a full system clear glass more at 9to 10 psig at -10F setpoint looking for feed back thank you

[@REFRIGERATIONKITCHENEQTECH]

I’m looking for a 0F to -4F box temp, nothing much colder than that. So let’s say we are aiming for 0F box temp. At that temperature, your superheat will be closer to 4-6F. This would give me a saturation of approximately-4F. At -4F saturation, my pressure would be 28PSI. At 10F to 15F box temp, that is when you will get your 6F to 10F superheat.

[@kirktrapp7001]

@@REFRIGERATIONKITCHENEQTECH tkank you

[@user-ot3zk5me5l]

So if the pressure are low enough they will freeze the coil? If the leak continues the coil would defrost overtime? It seems there are certain conditions that happen at certain pressures.

[@REFRIGERATIONKITCHENEQTECH]

Yes, low pressure = low saturation temperature, causing the coil to freeze up. If the coil continues to leak, the ice on the coil would get worse and start to cover more of the coil.

[@timbunner8855]

Did you use a delta-t of 10 to 15 degrees across the evaporator coil to subtract from the one degree temperature? Thank you Tim 863. 255. 9001

[@REFRIGERATIONKITCHENEQTECH]

10F TD evaporator for walk ins. This is just a general calculation to get us in the ball park so we can troubleshoot. The real calculation will be superheat.

[@DoctorLee81]

Send me a link on the torque tool

[@Brisket9392]

Drill a hole in a service cap to use for bubble testing so you don't have to get soap in there.

[@REFRIGERATIONKITCHENEQTECH]

👍 great suggestion

[@RedWhiteBlueYo]

Do you always use ambient air plus 15 or only on a freezer? Do you do ambient air plus 30 on like air conditioning sometimes or like if it was a regular walk-in cooler?

[@apprenticephil649]

If you drill a hole in a cap you can soap the cap and the leak will blow through and you won't risk soap getting in the system

[@REFRIGERATIONKITCHENEQTECH]

That’s a good tip

[@winkhvac62]

Where do you get that torch wrench?

[@REFRIGERATIONKITCHENEQTECH]

Sorry, which wrench?

[@winkhvac62]

sorry valve core torque tool

[@winkhvac62]

thank you for all your videos you are my mentor

[@REFRIGERATIONKITCHENEQTECH]

Ah gotcha, I just picked that up from united refrigeration, but any supply house should have it

[@MRICE-qe4sv]

Cork tape is the devil. The installer needs to be beat and shown how to use arms flex. And wth is that drain situation you got there?..

[@REFRIGERATIONKITCHENEQTECH]

Lol ya I hate that cork tape. The drain is just a sharkbite water heater hose. They are great for blowing out the drains during a maintenance.
