Powerful Design Tools for Real-World HVAC Projects

LG LATS is a robust HVAC engineering software platform that supports the entire design and planning process—from basic system layout to specialized segment solutions. Built with the needs of engineers, consultants, and technical partners in mind, LATS allows users to handle everything from load calculations and product selection to system layout, piping design, and cost-efficiency analysis.

Developed by LG, LATS bridges the gap between design and on-site application by aligning each stage with actual installation and maintenance conditions. It enables high-performance planning for complex systems, whether you're working on a standard building or a project requiring tailored HVAC configurations.

Seamlessly compatible with broader HVAC software ecosystems, LATS enhances design productivity and supports informed decision-making with simulation accuracy and time-saving features. From quick equipment selection to detailed system visualization, LATS offers a practical advantage in delivering efficient, competitive HVAC solutions.

Smart Tools That Power Intelligent HVAC Model Selection

ATS provides a powerful range of HVAC tools for model selection, helping designers make informed choices tailored to each project:

1. LATS Load is essential for HVAC design, calculating precise heating and cooling loads based on specific building details. It allows engineers to define zoning, building orientation, materials, and usage conditions to ensure accurate system sizing from the start.

2. LATS HVAC supports fast, accurate system selection and offers system validation to minimize HVAC troubleshooting later. With built-in simulation logic and LG product integration, it streamlines the design process and helps prevent mismatched equipment configurations.

3. LATS THERMA V is purpose-built for air-to-water heat pump projects, enabling energy simulation and cost payback estimation of heating loads as well as ideal model selection. It helps stakeholders evaluate long-term system performance and compare various configuration scenarios in terms of ROI (Return on Investment) and operational savings.

4. LATS Chiller and LATS Chiller ISC (Inverter Scroll Chiller) assist in chiller system selection with support for partial loads, efficiency modeling, and equipment documentation. These tools allow designers to optimize capacity planning and produce detailed spec sheets that align with regulatory and project-specific requirements.

5. LATS Vent is ideal for vent system design with HVAC system calculations, allowing users to simulate airflow and select the best-fitting model. It simplifies ductwork design by incorporating pressure loss analysis and automatic component matching based on air volume and flow requirements.

These HVAC tools dramatically cut down the manual work involved in creating a HVAC system diagram, making them indispensable in both residential and commercial HVAC design.

Design Smarter, Draft Faster: Automated Tools for HVAC Precision

LATS also offers two of the best HVAC software tools for automated design and reducing time spent on these tasks and minimizing integration errors:

1. LATS CAD integrates directly with AutoCAD, offering system blocks, smart piping layouts, and built-in validation to quickly create a duct sizing chart or system schematic.

2. LATS Revit serves as a BIM-compatible add-in for designing VRF systems. This 3D floorplan design tool enables automated piping and component placement, error correction, and even connects to CFD and HVAC simulation data for further refinement.

For contractors and engineers managing complex HVAC design projects, these automated tools transform time-intensive tasks into streamlined processes.

Full-Cycle HVAC Verification

Verification is key to ensuring a successful installation. LATS delivers some of the best HVAC software capabilities for design validation:

1. LATS Noise forecasts noise levels from outdoor units, helping designers meet project sound requirements.

2. CFD (Computational Fluid Dynamics) Analysis simulates airflow and temperature distribution via 3D modeling—useful in diagnosing potential hot spots and validating vent system design with HVAC system calculations.
