HVAC Engineering Services

HVAC stands for Heating, Ventilation, and Air Conditioning. It is an important part of both residential and industrial structures, providing thermal comfort and ideal conditions for working and manufacturing. Regarding our HVAC Engineering team at IntES, we have been offering HVAC Engineering services for various project scales and concepts, especially industrial projects with strict requirements of heat, air, humidity, etc.

What is included in a HVAC system?

There are three main elements of a HVAC system desgin. Our team of HVAC engineers deal with various aspects of this field, which mainly focus on:

  • H – Heating system: A heat pump system transfers heat from place to place for both heating and cooling purposes; other heating systems recover heat to reduce energy consumption.
  • V – Ventilation system: Supply/remove air utilizing natural forces to maintain indoor air quality and thermal comfort (Natural Ventilation); Use fans and ducts to control airflow in/out of a building/factory (Mechanical Ventilation); Smoke exhaust system and make-up air supply system; Ensure Indoor Air Quality (IAQ)
  • AC – Air-conditioning system: Chilled water system with Cooling tower; Air-cooled Chiller water system; Direct-expansion AHU System; VRF System; Package system / Split Units.

What HVAC Engineering services does IntES offer?

At IntES, our HVAC engineers are responsible for ensuring that the temperature and ventilation systems are optimised for the overall operation of the project, and provide the appropriate conditions required by our clients and regulatory bodies. For example, some special projects require varied-degree cold conditions such as cold storage facilities/warehouses, while others require room temperature or even warmer temperatures for certain purposes.
When coming to projects that include HVAC engineering tasks from our clients, our team usually takes on the following responsibilities:

  • Heating and cooling load calculations and reports
  • HVAC design drawing
  • HVAC specification
  • HVAC Computational Fluid Dynamics (CFD) Simulation
  • HVAC Selecting appropriate construction materials
  • Technical advice and consultancy
  • Survey and assessment of the HVAC of existing buildings

Our HVAC team’s approach to projects

Along with knowledge and experience through projects, we master a flexible approach to attain the targeted and specialized requirements. Depending on the scope of the project, our team uses various software/tools to provide detailed drawings or necessary analysis such as:

  • Autodesk AutoCAD
  • Autodesk Revit
  • Autodesk Navisworks
  • Cooling load calculation software such as Heat load, HAP, and Trace700.
  • CFD Simulation software
  • Natural ventilation simulation software

And for software calculation concerns ducting, piping, airside, and pressure loss:

  • ASHRAE Duct Fitting Database.
  • ASHRAE Psychrometric Analysis.
  • Duct Size Calculating.
  • Duct Checker.
  • Pipe Check Pro.

The first step of any project is always for our engineers to work with the client to assess the needs of their HVAC systems, clarifying the requirements to different areas in the project. Precisely defining those conditions helps our engineering team to start planning and developing detailed designs specifically tailored to the requirements of the project. Our engineers dedicate significant time to visiting the site, collecting necessary data, and starting to calculate and apply information to generate the drawings. In this stage, our engineers will decide which engineering software and tools to use while still sticking to the requirements and standards that need to be met.
