The demand for efficient and reliable cold storage solutions has never been more critical, especially in the food distribution sector. Texas Frio Cold Storage, a prominent meat distributor in Houston, TX, sought to expand its capabilities with a state-of-the-art refrigeration system for its new 45,000 square foot facility. Refrigerated Warehouse Construction (RWC), a Smart Care company, was selected for this project based on their previous work with the general contractor, KDW, and their reputation for delivering innovative refrigeration solutions.
Project Scope
RWC was tasked with designing and building a refrigeration system for Texas Frio's warehouse, which includes 37,000 square feet of freezer space, a 2,116 square foot meat cooler, and a 6,600 square foot dock, totaling 45,000 square feet of refrigerated space. The project's challenge was to implement a system that could efficiently operate in Texas's warm climate, which led RWC to opt for a subcritical CO2 cascade system paired with ammonia.
Design and Construction
RWC took six weeks to finalize the design, focusing on a cascade system utilizing ammonia on the high side and CO2 for evaporators and cooling. This choice was influenced by the necessity of a low-temperature solution in Texas' warm climate and the benefits of using subcritical CO2 systems, which operate at pressures below the critical point, making them more efficient in such conditions. The unique combination of ammonia, CO2, and glycol (created as a by-product and used to heat the floors) ensured an environmentally friendly solution and cost savings for Texas Frio.
Construction commenced in November of 2019, with RWC handling everything from design to equipment installation and startup. Stainless steel piping was used throughout the facility to ensure longevity and to prevent corrosion, a critical consideration for systems using ammonia and CO2.
Challenges and Solutions
Building a refrigeration system using both ammonia and CO2 in a cascade setup presented unique challenges. It’s an uncommon solution in the region, which necessitated specific approvals from Texas Frio. Additionally, this being the only system of its kind in Houston meant there was a steep learning curve in making it operate efficiently. Texas Frio relied on RWC's expertise and innovative approach to overcome these challenges, ensuring the system's successful implementation.
Outcome
The project was completed in November 2020, making it a year-long endeavor from design to startup. This customized refrigeration solution not only stands as a testament to RWC's engineering prowess but also as a unique and pioneering system within Texas. After nearly four years of utilizing the system, Texas Frio has achieved a remarkable 52% reduction in energy expenses compared to conventional hydrocarbon refrigeration systems. The use of ammonia, CO2, and glycol in a cascade configuration showcases a significant advancement in refrigeration technology, especially in regions facing the challenge of high (and increasing) ambient temperatures.
“Our experience with RWC has been excellent,” said Esmeralda De La Cruz, Managing Member of Texas Frio Cold Storage. “We have always been very happy with their professionalism and customer service. They are extremely knowledgeable on the refrigeration industry.”
Conclusion
RWC's successful design and implementation of the refrigeration system for Texas Frio's cold storage warehouse highlights the importance of innovation, technical expertise, and client-provider relationships in tackling unique industry challenges. The project not only serves Texas Frio's operational needs but also sets a new standard for refrigeration systems in the meat distribution industry, potentially inspiring future projects in Texas and beyond.
