Here in Chicago that is a foreign word and all I know is they do not get very hot and work kinda like an A/C unit in reverse.
I did a multi unit hi-rise 100 years old with this systen in place.
Here is a picture of what was on the roof.
Here is what is inside the 100 plus Living Units.
I know the boilers on the roof are Ajax 25 years old and I know the smaller units with the blowers are Snyder General with serial number J2671502 and Model number V024aegl on this one.
20 amps double breaker to it.
Top sheet metal is to ceiling vents (ducts)
It has freon so where does the hot exhaust go to?
I am used to a main hot water boiler and chiller unit (central) running H20 through an exchanger with blower in individual living units but this has me stumped.
Can someone give me a crash course here on the basics?
