Summary

In today's podcast episode, Jamie Kitchen talks about refrigeration controls and applications. He also tells us about the Danfoss ERC 213 universal digital controller.

Electronic refrigeration controls tend to have greater accuracy and flexibility than traditional electromechanical controls. These electronic controls also allow you to perform many more tasks than traditional ones. Electromechanical controls also wear out and lose their accuracy over time.

When you deal with applications that require various temperature, humidity, and defrost requirements, you can use electronic controls to choose between several options for the defrost method, defrost stop temperature, fan delay after defrost, etc. You can also put voltage and head pressure protection measures in place. You can optimize defrost and box temperature with electronic controls, but you can't control evaporator coil feeding. However, EEVs work well with these refrigeration controls and can adjust evaporator coil feeding. The ERC 213 has temperature and defrost sensors, but you can also configure it to work with other sensors, if you prefer.

The ERC 213 has seven different application settings (0-6). In cases where a preset option will suffice, choose between Apps 1-5. (Consult Resources for the ERC 213 installation guide, which explains each application.) However, you shouldn't assume that the electronic controls will have the same settings as mechanical controls. If you want to learn the full functionality of the ERC 213, you can use Apps 0 & 6 to customize parameters. Just remember to supply the correct voltage to the controller (120v).

Bryan and Jamie also discuss:

Customizable settings
Superheat controllers and EEVs
How defrost requirements change seasonally
Controlling compressors
Ice machines and restaurant refrigeration equipment

0:00.0	The episode is Dan Foss and Dan Foss.com.
0:06.0	Dan Foss, engineering tomorrow. This episode of the HVAC School podcast is made possible by our title sponsors.
0:27.0	I'm not really sure what a title sponsor is.
0:29.0	I think a title sponsor would be like if the name of the sponsor was in the show so maybe they're not
0:34.0	title sponsors but all I know is they're the ones who really invest in HVAC
0:38.3	school and make it possible which is a really a real thing and there are companies that
0:41.6	do invest in training and that is carrier,
0:44.4	Mitsubishi, electric, cooling and heating and refrigeration technologies.
0:49.4	And refrigeration technologies, I quickly want to mention them because they're not the largest
0:54.4	chemical manufacturer there's some really big chemical manufacturers
0:56.9	out there but refrigeration in technologies makes chemicals that are well
1:01.5	designed one thing you should know about them is they were actually found chemicals that are well designed.
1:03.0	One thing you should know about them is they were actually founded by a technician.
1:06.0	The founder of Refrigeration Technologies was actually a technician for 17 years
1:10.0	before he started refrigeration technologies and made products that are designed
1:14.6	for the field that are safe to use for technicians, safe for customers to be breathing
1:19.1	in their air, they look for it to make things as natural as possible. And if you've ever heard of the product
1:24.7	Nylog, well it's made by refrigeration technologies and it is a fantastic
1:28.1	product. You've heard me and Jim Bergman talk about it a lot, especially when
1:31.3	you're trying to pull deep vacuums and sealing threads and making flares.
1:35.3	It's a really, really good product.
1:36.6	And you may see their viper line.
