Summary

In this service manual talk-through episode, Eric Mele helps us discuss the Heatcraft Beacon 2 refrigeration system. We talk about what it can do and what it entails.

The Heatcraft Beacon 2 is a refrigeration system with more electronic controls than electromechanical. However, it is quite user-friendly, and it allows you to see what the system is doing at almost all times. The monitor doesn't allow you to adjust anything in the system, but it lets you see valve position, superheat, time until defrost, and more as the system is operating.

The Beacon 2 has a suction pressure transducer that maintains superheat. You can dial in the superheat on the control, and the system should control it almost exactly as long as all the components are working properly. You can also manipulate the wiring to run multiple evaporators off of one condenser. (There are master and slave evaporators, and you must differentiate them when configuring the controls.)

When it comes to parameters, you have to set your defrost type to air or electric. In general, you use electric defrost for freezers. You must also set your refrigerant type accordingly. Then, you set your box temperature. Medium-temperature applications tend to be around 35 degrees, and many low-temperature applications tend to be around -10 degrees. You also have control over defrost settings and temperature units (Fahrenheit or Celsius). You can also find frequent parameters on the evaporator panel for more information.

Most errors will be sensor errors. Many sensor issues are easy to test because of the user-friendly monitors. You can compare your reference sensor to the data to check the accuracy of what's being reported to the board.

Eric and Bryan also discuss:

Forcing pump-down and defrost
Schematics and wiring practices/applications
Headmaster valves
Setting pressure controls
Defrost frequency and failsafe

0:00.0	and This episode of the HVAC School podcast is made possible, truly,
0:19.6	made possible by our sponsors. And today I want to talk to you about carrier.com. They have some really
0:25.5	interesting things going on in their ducless and VRF lines. They actually have an RTU,
0:29.3	rooftop air handler that connects to VRF systems, is great for retrofits I saw it at
0:34.9	a-h-h-hr you can find out more by going to carrier.com also want to thank good
0:38.8	way good way makes all kinds of really good industrial grade,
0:43.7	commercial, heavy commercial grade,
0:45.2	cleaning equipment specifically built
0:47.3	for the HVACR industry.
0:49.8	And so everything from special cleaners
0:52.3	to clean cooling towers to automatic tube cleaners for
0:57.2	inside chiller barrels, lots of different technologies that you're going to want to check
1:01.2	out if you're anywhere in the industrial commercial side,
1:04.0	especially in chillers or water side of equipment,
1:06.0	that's where a good way comes in really handy.
1:09.0	We did a live video at their booth at HR,
1:12.0	and they gave us some really excellent demonstrations you can find that
