LG AIR CONDITIONER
TECHNICAL SOLUTION (LATS)
LG Air Conditioner Technical Solution (LATS) Software
A properly designed and installed refrigerant piping system is critical to the optimal performance of LG air-conditioning systems. To assist
engineers, LG offers, free of charge, LG Air Conditioner Technical Solution (LATS) software—a total design solution for LG air conditioning
systems. Contact your LG Rep for the best software program for your application.
To reduce the risk of designing an improper applied system or one that will not operate correctly, LG requires that LATS software be used on all projects.
Formats
LATS is available to LG customers in three user interfaces: LATS HVAC, LATS CAD2, and LATS Revit. All three LATS formats are available
through www.myLGHVAC.com, or contact an LG Sales Representative.
LATS HVAC is a Windows®-based application that aids engineers in designing LG Variable Refrigerant Flow (VRF), Multi F / Multi F MAX,
Single-Zone, and Energy Recovery Ventilator (ERV) systems.
*Windows®is a registered mark of Microsoft®Corporation.
LATS CAD2 combines the LG LATS program with AutoCAD®
software**. It permits engineers to layout and validate LG Multi V
Variable Refrigerant Flow (VRF), Multi F / Multi F MAX, Single-Zone,
and Energy Recovery Ventilator (ERV) systems directly into CAD
drawings.
LATS Revit integrates the LG LATS program with Revit®software**.
It permits engineers to layout and validate Multi V VRF systems
directly into Revit drawings.
**AutoCAD® and Revit® are both registered marks of Autodesk, Inc.
Features
All LG product design criteria have been loaded into the program,
making LATS simple to use: double click or drag and drop the com-
ponent choices. Build systems in Tree Mode where the refrigerant
system can be viewed. Switch to a Schematic diagram to see the
electrical and communications wiring.
LATS software permits the user to input region data, indoor and outdoor design temperatures, modify humidity default values, zoning, specify
type and size of outdoor units and indoor units, and input air flow and external static pressure (ESP) for ducted indoor units.
The program can also:
• Import building loads from a separate Excel file.
• Present options for outdoor unit auto selection.
• Automatically calculate component capacity based on design
conditions for the chosen region.
• Verify if the height differences between the various system
components are within system limits.
• Provide the correct size of each refrigerant piping segment and LG
Y-Branches and Headers.
• Adjust overall piping system length when elbows are added.
• Check for component piping limitations and flag if any parameters
are broken.
• Factor operation and capacity for defrost operation.
• Calculate refrigerant charge, noting any additional trim charge.
• Suggest accessories for indoor units and outdoor units.
• Run system simulation.
Features depend on which LATS program is being used, and the type of system being designed.

Introduction

LATS Generates a Complete Project Report
LATS software also generates a report containing project design parameters, cooling and heating design data, system component perfor-
mance, and capacity data. The report includes system combination ratio and refrigerant charge calculations; and provides detailed bill of
material, including outdoor units, indoor units, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe
size, and by pipe segments. LATS can generate an Excel GERP report that can imported into the LG SOPS pricing and ordering system.
Proper Design to Install Procedure
LG encourages a two report design-to-install-procedure. After the
design engineer determines building / zone loads and other details,
the engineer opens the LATS program and inputs the project’s
information. When the design is complete, the “Auto Piping” and
“System Check” functions must be used to verify piping sizes,
limitations, and if any design errors are present. If errors are found,
engineers must adjust the design, and run Auto Piping and Sys-
tem Check again. When the design passes the checks, then the
engineer prints out a proj ect “Shop Drawing” (LATS Tree Diagram)
and provides it to the installing contractor. The contractor must
follow the LATS Tree Diagram when building the piping system, but
oftentimes the design changes on the building site:
• Architect has changed location and/or purpose of room(s).
• Outdoor unit cannot be placed where originally intended.
• Structural elements prevent routing the piping as planned.
• Air conditioning system conflicts with other building systems (plumbing, gas lines, etc.).
The contractor must mark any deviation from the design on the Shop Drawing, including as-built straight lines and elbows. This “Mark Up”
drawing must be returned to the design engineer or Rep, who must input contractor changes into the LATS file. (Copy the original LATS soft-
ware file, save and rename as a separate file, and modify all piping lengths by double-clicking on each length and editing information.) Like
the shop drawing, the Auto Piping and System Check must also be run on this new “As Built” drawing. The design engineer or Rep must then
provide the final As Built file to the contractor. The Mark Up version must be compared to the As Built version for the following:
• Differences in pipe diameter(s). If incorrect diameters have been installed, the piping must be changed out. If pipe diameters have changed,
check to see if Y-Branches will also need to be changed.
• Changes to outdoor unit and indoor unit capacities. Capacities changes may impact line length changes.
• Additional refrigerant charge quantity (“Trim Charge”). Trim charge will change if piping lengths and diameters change. The As Built version
must reflect installed piping lengths to ensure correct trim charge.
All documents submitted by the contractor, as well as the Shop Drawing and the As Built Drawing files must be provided for commissioning
purposes. Model and serial numbers for all system components must also be submitted. If the steps previously detailed are not followed, and
all documents are not provided to the LG trained Commissioner, the project runs the risk of not being commissioned and voiding any limited
warranty LG offers on the equipment.

• Measurements are taken 3.3 ft away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of
±1.
• Data is valid at nominal operation conditions. Operating conditions
are assumed to be standard.
• Reference acoustic pressure 0dB=20μPa
• Sound pressure levels are tested in an anechoic chamber under
ISO Standard 3745, and may be different according to the test
condition or equipment.
• Sound level will vary depending on a range of factors including the
construction (acoustic absorption coefficient) of a particular room in
which the unit was installed.
