SELECTION PROCEDURE

1. Determine design conditions:-Given:Total Cooling Capacity ......................................... 94kWSensible Heat Capacity ....................................... 70kWEvaporator Air Quantity .................................... 4250l/sExternal Static Pressure .................................... 200PaMixed Ent Air Conditions (tedb) ............................................................. 28C DB (tewb) .............................................................. 9.5 WBCondenser Entring WaterTemperature .......................................................... 30CDesign Temperature Rise ....................................... 5C

2. Select based on cooling requirements.

a. Enter 50BP cooling capacity table at given evaporatorair quantity (4250l/s) and condenser leaving temperature(35C). Determine total cooling capacity (TC) and sensibleheat capacity (SHC) at given entering air wb (19.5C).A 50BP340 unit has capacity of 96.0 kW (TC) and69.7kW (SHC) with compressor power input of 25.8 kW.

b. Correct SHC value for entering air temperature otherthan 27C.SHC' = SHC = 1.23(1-BF) (tedb-27) (l/s/1000)

= 69.7 + 1.23(1-0.08) (28-27) (4250/1000)= 74.5kW

Correct SHC = 74.5kWThus, 50BP340 unit can fulfill the specified loadrequirement.

3. Determine static pressure.

From 50BP340 Fan Curve:Locate on the curve where the specified air quantity(4250 l/s) and external stat ic pressure (200 Pa)intersect.

The intersect point is under 5.5kW line and fan rpmcan be determined as 910 rpm. The standard 5.5kWmotor can satisfy the requirements.

4. Determine condenser water requirements.

a. Requirement water flow can be determine using theformula below:= TC (kW) + Power Input (kW) Water Temp Rise (C) x 0.07

= 96.0 + 25.8 = 121.8 5 x 0.07 0.35

= 348 l/min

b. Enter condenser pressure drop chart at the determinedwater flow 348l/min. Read from the intersection on thecurve to the left scale to obtain the water pressuredrop (2 kPa). A proper water pump can be selectedbased on this value.

CAPACITY NOTES

1. Gross capacities do not include deduction for indoorfan motor heat.

2. SHC is based on 27C DB temp of air entering indoor unit.Correction based on the following formula is necessaryif the air temperature is below or above 27C DB.

SHC' = SHC + 1.23(1-BF) x (tedb-27) (l/s/1000)

WhereSHC' : Sensible heat capacity corrected, kW.SHC : Sensible heat capacity in the table, kW.

3. Direct interpolation is permissible. Do not extrapolate.

4. Nominal capacity is based on max. air quantity, 19.5Centering wet-bulb and 35C condenser leaving watertemperature.

CONDENSER PERFORMANCE

Notes:1. The following Condenser Pressure Drop values are

based on the fouling factor of 0.044 m2K/kW2. Water flow rate can be calculated using the formula
