Jul 03, 2019 · Fan Coil Units. In this article, we are going to be looking at FCU’s. FCU stands for fan coil unit but often engineers will just call them a fan coil, to save time. Fan coil units are very common in all types of buildings, from offices, bars, canteens, even some homes and apartments will have a fan coil unit in them.
from a piston outdoor unit and a fixed meter coil. Back to coil sizing, Trane rates its matches with all kinds of indoor coils. I use the same size indoor coil as outdoor unit. But looking at the chart, putting a TXA-048 coil on a 7A0036 gives a hair more sensible capacity, but NO difference in latent and probably will run a warmer discharge.
The ground end of the coil should be collocated with the coax shield ground. The coil at right has 9 turns, is 1 inch inside diameter, and wound with #14 Thermalese ® (enameled) wire. The coil's form factor should be kept close to 1:1 (length to diameter). Long skinny coils do not work nearly as well.

The Q of a coil. Q = 2πfL ÷ R Where f is frequency in Hertz and R is the Resistance of the coil. The Q of a coil is dependent on a number of relative factors such as physical size, wire diameter, form factor, etc. To obtain highest Q: Choose a size of coil where the length is moderately greater than the diameter;
Enter 12 volts and 4.60 amps into the calculator and it will show the coil resistance as 2.61 ohms. Enter 24 volts and 2.15 amps into the calculator and it will show the coil resistance as 11.16 ohms. Now that you know the resistance value of each type of coil, you can quickly grade each rotor. (Don't forget to mark them!). Helpful links:

PIPE SIZING continues from page 92 Let’s use a hydronic distribution example, where we are sizing a pipe to carry 180°F fluid from a boiler to a fan coil that requires 30,000 BTUH. The owner wants to use 30 per cent PP glycol to prevent a frozen system in case of an extended power outage.
Sweat Connection = Connection Size + 1/8” (e.g. Coil with 1” MPT connections, header OD = 1 1/8” Exceptions: Non-Freeze Steam Distributing coils have fixed header diameters regardless of connection size. 1 Row Steam Dist. Coil = 2-5/8” OD Header, unless supply is 3” than header is 3 1/8” 2 Row Steam Dist. Coil = 3-1/8” OD Header
Simply weigh the coil, then use the chart to find a size wire that weighs just as much at the desired resistance. You can double check it by using the resistance for the length of wire. It should be within about 5% of the resistance by weight.
