TZCAC- SELECTION PROCEDURES1. Determine cooling and heating requirements at design

conditions.Example:

Total cooling capacity ............65,000 BTUH [19.04 kW]Sensible cooling capacity ......49,000 BTUH [14.36 kW]Condenser entering air ..........95°F [35°C]Evaporator entering air............63°F [17°C] wb/76°F [24°C] dbIndoor air flow ........................2050 CFM [967 L/s]External static pressure..........2.0 in wg

2. Select unit to meet cooling requirements.Since total cooling is within the range of 6 ton [21.1 kW] unitenter cooling performance from the TZCAC072 table, at 95°F[35°C] outdoor temperature, 63°F [17°C] wb entering indoorair, and 2050 CFM [967 L/s]:

Total capacity..........................68,800 BTUH [20.17 kW]Power input ............................5.2 kW

And also, at 76°F [24°C] db indoor entering air, and using the formula at the bottom of the page:

Sensible capacity....................52,304 BTUH [15.33 kW]

3. Determine blower speed and power to meet the systemrequirements.At the given external static pressure of 2.0 in wg, the beltmodel must be selected. Enter the belt drive blower perfor-mance table at 2050 CFM [967 L/s] and 2.0 in wg ESP:

RPM....................793Watts ..................690Drive ..................L

4. Calculate indoor blower BTUH heat effect.BTUH = Watts x 3.413 = 2355

5. Calculate net cooling capacities.Net total cooling = 67,500 – 2355 = 65,145 BTUH [19.09 kW]Net sensible cooling = 52,304 – 2355 = 49,949 BTUH [19.08 kW]
