25th Tehran International HVAC&R Exhibition 2026: Key Trends in the Building Services Industry

The 25th International Exhibition of Heating, Cooling, Air Conditioning and Ventilation Systems was held from 28 September to 1 October 2026 at the Tehran International Permanent Fairground. The specialized event provided an opportunity to present HVAC&R equipment, technologies and solutions and to connect manufacturers with contractors, consultants, developers and other industry professionals.

What Was the 25th Tehran HVAC&R Exhibition?

The Tehran HVAC&R Exhibition is a specialized event for the building services and mechanical systems industry. It brings together different parts of the HVAC&R value chain, including cooling and heating equipment, air conditioning systems, refrigeration equipment, mechanical building services, piping and fittings, and building automation solutions.

The value of such an exhibition goes beyond displaying products. Selecting the right HVAC system for a building depends on cooling and heating loads, building use, climate, available space, initial cost, energy consumption, maintenance requirements and spare-parts availability. A specialized exhibition allows engineers and decision-makers to compare different approaches in one professional environment.

Date and Venue

The 25th International Exhibition of Heating, Cooling, Air Conditioning and Ventilation Systems took place from 28 September to 1 October 2026 at the Tehran International Permanent Fairground. The announced visiting hours were 8:00 AM to 3:00 PM.

The event brought together companies active across different areas of building services and created opportunities for business discussions, technology discovery and a closer understanding of market requirements.

Main Exhibition Areas

Cooling Systems

Cooling equipment is one of the central categories at HVAC&R exhibitions. In residential, commercial, office, hospitality and industrial projects, cooling systems should be selected according to required capacity, climate, operating profile and installation requirements.

Split air conditioners and ducted split systems are widely used for independent applications, while central systems such as chillers and fan coils are suitable for projects with broader cooling and heating requirements. Variable refrigerant flow systems can also be considered when independent zone control and installation flexibility are important.

Heating Systems

Heating equipment is another important part of building services. Good heating performance depends not only on equipment capacity but also on building insulation, climate, occupancy, heat distribution and temperature control.

The main objective of heating design should be thermal comfort with reasonable energy consumption. Efficient equipment and accurate controls can therefore contribute to lower operating costs and more stable indoor conditions.

Air Conditioning and Indoor Air Quality

Air conditioning is not limited to cooling or heating a room. Indoor air quality, ventilation rates, filtration, humidity control and thermal comfort are also important parts of HVAC design and operation.

ASHRAE identifies indoor environmental quality as an important part of building performance and emphasizes the relationship between HVAC design and operation, indoor air quality, health and occupant comfort.

For new projects, HVAC systems should therefore be selected with a balanced view of air quality, thermal comfort and energy performance.

Refrigeration and Cooling Equipment

Cold-chain applications in retail, food storage, hospitality and specialized industries depend on reliable refrigeration systems. Stable operation, temperature control, serviceability and spare-parts availability are important factors when evaluating refrigeration solutions.

Building Automation and Energy Management

A major direction in building services is the shift from simple controls toward intelligent equipment management. Building Management Systems, or BMS, can collect equipment data and support monitoring and control of heating, cooling and ventilation systems.

Smart controls create the greatest value when they are combined with proper system design, suitable sensors, correct settings and a clear operating strategy. Simply adding control equipment does not automatically guarantee energy savings.

Energy Efficiency: A Major HVAC&R Priority

Energy efficiency has become a major priority in building design and operation. The International Energy Agency reported in Energy Efficiency 2025 that buildings account for around 30% of global energy demand and highlighted efficient cooling equipment and better building design as important measures for controlling energy growth.

In this context, efficient HVAC equipment is not only an economic advantage but also part of a more sustainable building strategy. Good insulation, correct equipment sizing, intelligent controls, regular maintenance and high-efficiency equipment should be considered together.

Why the Exhibition Matters to Engineers and Developers

For consultants, contractors and developers, an exhibition provides an opportunity to compare solutions and communicate directly with manufacturers. Questions about capacity, efficiency, warranty conditions, after-sales service, spare parts and installation requirements can help clarify the real lifecycle cost of a system before purchase.

For end users, the same principle applies. The cost of an HVAC system is not limited to its purchase price. Electricity consumption, maintenance, repairs, spare parts and expected service life should also be considered in the final decision.

Green Solutions for the Air Conditioning Market

Green provides air-conditioning solutions including split air conditioners, ducted split systems, GRV systems, chillers and fan coils. This product portfolio allows different solutions to be considered for projects with different technical requirements.

For projects requiring ducted systems, see Green Duct Split. For central applications, Green Chiller and Fan Coil can be evaluated. Projects requiring VRF technology can explore Green GRV, while independent spaces can be served by Green Air Conditioners.

Equipment selection should always be based on the actual project requirements, load calculations, climate conditions and design constraints rather than brand name or nominal capacity alone.

The Future of HVAC&R

The HVAC&R industry is moving toward higher efficiency, more precise control, greater connectivity and smarter energy management. Growing demand for cooling in many markets is also increasing the importance of equipment efficiency.

Building design remains equally important. Reducing thermal loads, improving the building envelope, sizing equipment correctly and applying intelligent controls can help HVAC systems operate with appropriate capacity and lower energy use.

Specialized events such as the Tehran HVAC&R Exhibition provide a useful setting for observing these developments and understanding the direction of the industry.

Conclusion

The 25th Tehran International HVAC&R Exhibition was held in September–October 2026 and once again highlighted the importance of HVAC&R within building projects and the wider construction sector. Energy efficiency, indoor air quality, smart controls, efficient equipment and after-sales support are becoming increasingly important factors in HVAC decisions.

The final system selection should be based on engineering calculations, project conditions and lifecycle cost. Comparing alternatives and obtaining professional advice can reduce the risk of selecting an unsuitable system.

If you are evaluating cooling, heating or air-conditioning solutions for a project, explore Green products and contact the Green team for guidance on selecting an appropriate solution.
