Introduction
Introduction
1. Preface
R410A Model
is the most favored choice when there is a need for precise air conditioning of relatively big pro-
jects extending from Multi-Room structure to big commercial places. We have a big line up, that offers wider
flexibility of model selection.
Equipped with inverter technology and long piping installation, the product matches well if one talk about opti-
mum power consumption in high rise buildings. Add on capacity feature makes it easy to upgrade the existing
capacity at any time.
With the growing concern about environment preservation, comes with R410A refrigerant which is
environment friendly and thus our system is a high technology and environment friendly product.
Unique refrigerant flow and electronic circuit control gives this system an unique capability to work in
extreme/abnormal working conditions making our customer feel great about their decision of selecting
LG as their first choice.
This publication provides a detailed and in depth information about the design and installation of .
We hope that with this information you would become an expert of your system.

Introduction
2. Step by Step System Selection Process
(1) Calculate or obtain the maximum heat load for the area(s) to be air conditioned
Decide the indoor unit specifications
Decide the outside unit specifications
Capacity coefficient factor
Decide the air velocity and temperature distributions
Decide the cooling tower specifications
Decide the boiler specifications
Decide the water pump specifications

•Ratio of the running Indoor Units to the Outside: Within 10 ~ 100%
•A combination operation over 100% cause to reduce each indoor unit capacity.
■Combination Ration(50~200%)
Notes:
* We can guarantee the operation only within 130% Combination.
If you want to connect more than 130% combination, please contact us and discuss the require-
ment like below.
1) If the operation of indoor unit is more than 130%, low airflow operation is recommended in all
the indoor units.
2) If the operation of indoor unit is more than 130%, additional refrigerant is needed according to
the headquarter guidance.
3)Over 130%, capacity is same as capacity of 130%, Same remark is valid for power input.
