General Description

Thank you very much for your special patronage of LG air conditioners.

LG’s "Roof Top or Single Package" is an ideal choice when we talk about high load applications.

As the name Roof Top signifies, this unit is generally installed on the top of the roof. Also the Single Package

signifies that both condenser and evaporator are enclosed in a single body(same as window type). The unit is

used along with ducts and has flexible air flow as per installation conditions. The air flow can be horizontal or

vertically downward which offers wider flexibility in the field applications.

Apart from common features, this unit offers some unique features like High & Low static driver kit, Oversize

motor option, Manual Hood for fresh air intake, Compact design etc.

This unit is ideal for Single story and Double story houses as they offer high static.

With its easy installation and simple controlling system, this products is suitable for Factories, Shopping malls,

Multiplex, Hotels etc.

A lot of information regarding the design & installation of this system is provided in this publication. This newproducts series contains data on the same pattern.

Please utilize all the information for conducting your business efficiently.

3. Features & Benefits

Cooling, Heating & Fan Operation :- LG air conditioners can provide cooling, heating & fan operation. In the cooling mode, it cools the air with an

operation range of 18~30°C. In the heating mode, it heats the air with an operation range of 16~30°C. In the

fan operation mode, only indoor fan at the selected speed will run, outdoor fan and compressor will be off.

Auto Restart Operation :- Whenever there is electricity failure the system shuts off and resumption of the power, unit will start in the

same mode as prior to the power failure. Memorized condition are on / off condition, operating mode (cool-

ing/heating), set temperature and fan speed.

LCD Wired Remote Control :- It can control all the functions of the unit. You can

check/set temperature, change operation mode,

set timer & also diagnose the error of the unit. It

also has the weekly program.

Two Thermistor Control(Return Air Control):(Accessory)-There may be a significant difference between the return air temperature in the duct and the room temperature.

Return air sensing tempeaturee is designed to control temperature more accurately by applying additional ther-

mistor which senses the return air temperature inside the duct specially.

After selecting the duct thermistor, which is connected to the main PCB, the room temperature measurement

by LCD wired remote control thermistor is neglected. It helps to control the room temperature more accurate-

ly.(Thermistor is a field-installed accessory)

Group Control :- It enables to control max of 16 units with the help of

one wired remote controller. All the units will follow

same setting of temperature & other sub functions.

CHILD LOCK-Display

Child Lock Function :- It prevents the children or others from tampering

with the control buttons. Unit can be controlled bythe wireless remote controller.This can be easily setby pressing timer key & Min keysimultaneously.After child lock is set, by pressingany key CL will be displayed on the LCD for 3 sec-onds and all the keys are ineffective.

Time Delay Safety Function :- It delays restarting of the compressor by three minutes thereby preventing damage to the compressor .

Self Diagnosis Function :- This function provides diagnosis of the unit. An error code will be displayed on the LCD wired remote con-

troller & diagnosis can be done as per the code indication.The same is also printed on key cover of the LCDwired remote controller.

Central Control :(Accessory)- It enables to control 16 x 8 = 128 units with the help

of 8 controllers. All units can be put on and off fromone Central Room.For Setting Temperature, FanSpeed and other sub functions, access the LCDwired remote controller of each unit.

Zone Control :(Accessory)- It controls the temperature of each zone. Opening or

closing of the damper is controlled by sensing the tem-perature of each zone.In the cooling mode, if the tem-perature of a particular zone is lower than set tempera-ture then the damper is closed. On the other hand, ifthe temperature of a particular zone is higher than theset temperature damper is open to provide cooling tothe zone and vice versa in the heating mode.

Step 3. From table-3 (LK-C3608H00), at 12,000 CFM and 95°F DB outdoor ambient temperature, with80°F DB. 67°F WB air entering temperature.Total cooling capacity= 360,000 Btu/h, Sensible capacity = 270,000 Btu/h

To find capacity at intermediate conditions not in the table.

Interpolation should be used when design conditions are between two numbers that are in thecapacity table. Extra-polation is not recommended.

Step 4. The capacity estimated at step #3 is the gross capacity of the selected unit. The generated heatfrom indoor motor is a function of CFM & static pressure. The total unit static pressure, is as follows:

Evaporator fan motor performance table has deducted the pressure drop for filter already in the unit.Therefore, the actual total static pressure is 0.80 in.Aq. With 12,000 CFM and 0.80 in.Aq., table-5 shows 6.12 BHP for this unit. FAN MOTOR HEAT;3.1 x BHP = MBH3.1 x 6.12 = 19.0 MBHNow subtract the fan motor heat from the gross cooling capacity of the unit;

Step 5. If the selected unit performance will not meet the required load, either total or sensible cooling, thenext higher size unit should be selected.

Step 1. Calculate the building heating load using the ASHRAE calculation or from other standard acceptedmethod.

Step 2. The required heating capacity is 120,000 Btu/h.The electric heat accessory capacities are listed in table-8.From the table-8 select, 36 kW electric heater with output122.86 MBH = 122,860Btu/h.

External Static(Duct system) 0.64 in.Aq.

Standard Filter 0.16 in.Aq.

Step 4. The capacity estimated at step #3 is the gross capacity of the selected unit. The generated heatfrom indoor motor is a function of l/s & static pressure. The total unit static pressure, is as follows:

Evaporator fan motor performance table has deducted the pressure drop for filter already in the unit.Therefore, the actual total static pressure is 20.32 mm Aq. With 5,663 l/s and 20.3mm Aq., table-4 shows 4.57 BkW for this unit. FAN MOTOR HEAT;1.22 x BkW = kW1.22 x 4.57 = 5.58 kWNow subtract the fan motor heat from the gross cooling capacity of the unit;

Step 5. If the selected unit performance will not meet the required load, either total or sensible cooling, thenext higher size unit should be selected.

Step 1. Calculate the building heating load using the ASHRAE calculation or from other standard acceptedmethod.

Step 2. The required heating capacity is 35.19kW (given).

The electric heat accessory capacities are listed in table-8. From the table select, 36kW ElectricHeater with output 122.86MBH.

External Static(Duct system) 16.26 mm Aq.

Standard Filter 4.06 mm Aq.

Electric heater size 36kW 4.06 mm Aq.

Total static pressure 24.38 mm Aq.

Net cooling capacity 105.5 kW - 5.58 kW = 99.92 kW

Net sensible cooling 79.1 kW - 5.58 kW = 73.52 kW
