Initial Requirement:

In 2020 (1399), the Municipality of Shahr-e Rey aimed to equip and operate the Shahid Firefighters Pool in the region. They sought a system capable of providing centralized, cost-effective heating and cooling for the facility with minimal need for auxiliary infrastructure.

Given the physical constraints of the project site and the limited space for mechanical rooms, using separate systems (independent chillers and air handling units) was not cost-effective in terms of installation, maintenance, and implementation time. The client also required a solution that could provide precise temperature control, simultaneous operation across different seasons, and ease of service and maintenance.

Solution:

After evaluating the project conditions and the functional requirements of the pool, our technical team proposed an integrated rooftop package unit equipped with a hot water coil as the optimal solution.

By combining heating and cooling units in a single device, this system provides conditioned air with precise temperature and humidity control, eliminating the need for extensive infrastructure.

Careful design of the air distribution paths and strategic placement of the unit on the roof not only increased energy efficiency but also reduced operating noise and enhanced environmental comfort.

The unit’s digital control system was configured to automatically adjust the operation of the compressors and the hot water coil under varying temperature conditions, ensuring energy consumption remains at the minimum level.

Result:

With the installation and commissioning of this rooftop package unit, the Shahid Firefighters Pool in Shahr-e Rey now benefits from an integrated, efficient, and low-cost operational system.

The system performed excellently during initial testing, maintaining stable temperature and proper ventilation throughout the pool area under varying thermal conditions.

The choice of an integrated solution and precise installation design enabled the Municipality of Shahr-e Rey to put the facility into operation more quickly while significantly reducing operational and maintenance costs compared to conventional systems.

This project stands as a successful example of combining practical engineering with optimal design in public facility HVAC systems.
