I’m Fresh out of school and I got into a commercial/ industrial HVAC company. I want to get into the refrigeration side of things. I’ve been told it’s a hard game to play. Thanks for your videos.

Love the way you explain stuff... Way better than my teacher when I took HVAC. I'm a Mechanical Engineer with a Bachelors degree... I got into HVAC as a retirement career after developing the first infrared hand held refrigerant detector with 2 other individuals. Keep the vids coming.

I love your clear board for your drawing presentation in your videos. It's the best HVAC/R academic presentation on KZitem I've seen. I'm a licensed HVAC technician. I have one concern with this video. Please correct me if I am in error. The N.C. contacts you have completing the control circuit for the compressor actually do not. Those N.C. contacts send control voltage to the t'stat located inside the refrigerated space. Whenever rhe t'stat contacts close, it completes the control circuit for the liquid line solenoid coil which energizes the solenoid coil which opens the liquid line solenoid valve, allowing liquid refrigerant to feed the metering device which feeds the evaporator coil which causes the low side pressure to rise to the cut-in pressure setpoint of the low pressure safety switch which closes the contacts inside the low pressure safety switch which then sends control voltage to the compressor contactor coil which energizes that coil, causing it to close the N.O. contacts on the contactor, thereby sending line voltage to the compressor motor which brings on the compressor for refrigeration mode. There is more to this on the refrigeration side of the timer comtol. There is the circuit for the evaporator fan as you mentioned, but I won't go into that sequence of operation. I just wanted to point out the part that involves the N.C. comtacts for the compressor actually directly feed the t'stat, not the compressor contactor coil. I will be viewing more of your videos. I have already watched others. Just recently found your channel and subscribed. Please keep up the great work you're doing!! Again, your presentation is EXCELLENT!!

First thank you for your kind words. I enjoy teaching and do this to help some of the guys out there in the field. Thank you for the information you ere sending me about the operation. I read what you were describing and I can see how that system works. it makes perfect sense the way you described it. I go and see whatever my ex-students ask me to come and see whether it is AC, Refrigeration or controls in their buildings. your description is of a more complicated system then I was describing and or what Paragon timer actually describes in their manuals. BUT Yes you were correct in your description, I just could not cover all of the different scenarios. Thank you for writing, and subscribing.

in solenoid type how can you control the defrost time as its connected in series with defrost thermostat !

Thank you for your question!!! That solenoid is the coil for a relay. if you look at time 11:42 I talk about it being a relay. and how that will control the heater, the compressor and fan. I guess I should have called it more times relay coil in stead of solenoid. Thank you!!!

There are several things that I would like to do. And that would be one of them, I just don't know if I have the time. I will try, thank you for your suggestion! I just finished up a class that I've been teaching all day so my schedule is so full right now! Thank you, have a good day, and I'm glad you watch that video!
