 VAV With Hot Water Reheat Coil Terminal Unit  A to Z Products
 Introduction
 
COSMOS make single duct variable air volume with hot water reheat coil is attached to the discharge of the terminal casing. Hot water coil casing is constructed with 22 gage galvanized steel.

The discharge end of the casing has slip and drive connection for easy attachment to downstream ductwork.

 
  Hot Water Coil Construction Details
 
Hot water reheat coils are factory mounted on the discharge of the terminal.
Coils are enclosed in 22 gauge coated steel casing with slip and drive connection.
Fins are rippled and sine wave type constructed from heavy gauge aluminum, mechanically bonded to the tubes.
Tubes are copper with a minimum wall thickness of 0.016" with male solder header connections.
 
 Selection Procedure
 
Correction Factors:
 
 
ΔT = (Entering water temperature ‐ Entering air temperature differential)

Above table shows correction factor ΔT. (Difference between Entering Water Temperature (EWT) and Entering Air Temperature (EAT)). If this ΔT is suitable, proceed directly to the tables for selection.

Multiply MBH values obtained from selection tables by the appropriate correction factor above to obtain the actual MBH value.

For Variable Air Volume Applications, the static pressure drop must be based on the maximum air volume. Air and water side pressure drop can be read directly from the tables.

Fundamental formulas to calculate Leaving Air Temperature (LAT) and Leaving Water Temperature (LWT) are given below.

LAT = EAT + ( (BTUH / (1.085 X CFM ) )

LWT = EWT ‐ ( (BTUH / (500 X GPM ) )

Terms

LAT= Leaving Air Temperature (°F)

EAT= Entering Air Temperature (°F)

MBH=1000 BTUH ( BTHU= British Thermal Units per Hour )

BTUH= Coil Heating Capacity

CFM= Air Volume (Cubic Feet per Minute)

LWT= Leaving Water Temperature (°F)

EWT= Entering Water Temperature (°F)

GPM= Water Capacity (Gallons per Minute)
