GCS16 UNIT WITH EMDH16M HORIZONTAL ECONOMIZER


To determine sensible capacity, leaving wet bulb and dry bulb temperature not shown in the rating tables use the methods below.

Leaving Wet Bulb (Imperial Units) 1. cfm x 4.5 = lbs. of air per hour

2. Btuh cooling capacity = Btu's per lb. of air lbs. of air per hour

3. Refer to enthalpy table below for entering wet bulb to determine Btu per lb. of air.

4. Subtract the result of #2 from #3 for Btu per lb. of air. 5. Match the result of #4 on the enthalpy table to obtain the leaving wet

bulb required.

Example: 1. 4500 cfm x 4.5 = 20,250 lbs. of air per hour

2. 120,000 Btuh cooling capacity = 5.93 Btu per lb. of air 20,250 lbs. of air per hour

3. Entering wet bulb of 67°F = 31.62 Btu per lb. 4. Subtract 5.93 from 31.62 = 25.69 Btu per lb. 5. From enthalpy table 25.69 Btu per lb. equals 58.8 leaving wet bulb.

Leaving Dry Bulb (Imperial Units) Leaving dry bulb = entering dry bulb _ Sensible heat capacity (Btuh)

1.08 x cfm Sensible capacity = SIT x total capacity

To determine sensible capacities at dry bulb temperatures not shown in the cooling unit tables, apply the following correction factor.

Dry bulb temperatures higher than table figure: Add 900 Btuh per 1000 cfm/°F

Dry bulb temperatures lower than table figure: Subtract 900 Btuh per 1000 cfm/ 0 F.

Example: From table@ 4500 cfm- 80°F dry bulb- 67°F wet bulb.75 SIT ratio - 120,000 Btuh total cooling capacity

What is sensible capacity and leaving dry bulb for 78°F dry bulb@ 67°F wet bulb?

Sensible capacity@ 80°F dry bulb/67°F wet bulb = .75 SIT x 120,000 Btuh = 90,000 Btuh

Sensible capacity@ 78°F dry bulb/67°F wet bulb

90,000 Btuh _ 900 Btuh x 4500 cfm x 2°F 1,000 cfm

= 90,000 Btuh - 8,100 Btuh = 81,900 Btuh

Cataloq 278 I Paae 39

To determine sensible capacity, leaving wet bulb and dry bulb temperature not shown in the rating tables use the methods below.

Leaving Wet Bulb (Metric Units) 1. Cooling capacity kilowatts (kW) x 3600 = kilojoules per hour (kJihr) 2. Litres per second (Lis) x 4.68 = kilograms of air per hour (kglhr) 3. Enthalpy (hs) = kJihr _,_ kglhr = kJikg of dry air 4. Refer to enthalpy table below for entering wet bulb to determine kJikg

of air. 5. Subtract the result of #3 from #4 for kJikg of air. 6. Match the result of #5 on the enthalpy table to obtain the leaving wet

bulb required.

Example: Cooling unit capacity 35.16 kW and 2124 Lis Temperature condition, entering wet bulb 19.4°C 1. Cooling capacity 35.16 kW x 3600 = 126,600 kJihr 2. 2124 Lis x 4.68 = 9940 kglhr of air 3. hs = 126,600 kJihr _,_ 9940 kglhr = 12.74 kJikg of air 4. Entering wet bulb of 19.4°C = 55.54 kJikg (from enthalpy table) 5. Subtract 12.74 from 55.54 = 42.80 kJikg 6. From enthalpy table 42.80 kJikg equals 15.2°C leaving wet bulb

Leaving Dry Bulb (Metric Units) Leaving dry bulb = entering dry bulb _ Sensible heat capacity (Watts)

1.21 x Lis Sensible capacity = SIT x total capacity

To determine sensible capacities at dry bulb temperatures not shown in the cooling unit tables, apply the following correction factor.

Dry bulb temperatures higher than table figure: Add 1.0 kW per 1000 Lis per oc

Dry bulb temperatures lower than table figure: Subtract 1.0 kW per 1000 Lis per oc

Example: Cooling unit capacity 35.16 kW and 2124 Lis, SIT ratio = 0.75 Temperature conditions, entering DB 25.6°C, entering WB 19.4°C

Sensible heat capacity (from cooling unit tables) at 26.JDC dry bulb and 19.4°C wet bulb = 0.75 SIT ratio x 35.16 kW = 26.37 kW

Sensible heat capacityy at 25.6°C dry bulb, 19.4°C wet bulb

26.37 kW _ 1.0 kW x 2124 Lis x (26.7 - 25.6°C)

1000 Lis 26.37 kW - 2.34 kW 24.03 kW = 24,030 W

Leaving dry bulb = 25.6°C 24,030 W 1.21 x 2124 Lis

= 25.6°C - 9.35°C = 16.25°C
