Latin America. Dos Bocas is a project for an oil refinery in Tabasco, Mexico, that led Hisense HVAC to develop a copper fin anticorrosive system for the heat exchangers of the outdoor units of VRF systems. The refinery, owned and operated by the parastatal company Petróleos Mexicanos, will process an average of 340,000 barrels of oil per day.
For now it is being developed as part of Mexico's December 2018 National Refining Plan that aims to reduce its dependence on U.S. fuel imports. Once built, it will be the largest refinery in Mexico.
As this work is an oil refinery project, the anti-corrosion requirements are very high. Unlike projects in coastal areas, the main corrosive agent in this type of facility is sulfide and the necessary anti-corrosion schemes are difficult to meet with standard anti-corrosion solutions. For this reason, the use of copper fins in the heat exchanger is mandatory.
"This is a big challenge for us," said Vinsen, Hisense HVAC's technical director for the Americas. "The implementation of copper fins in heat exchangers for large outdoor units would be the first time that work has been done in our factory and also something that does not yet exist in the VRF system market."
After a good number of discussions between various parties, finally Hisense HVAC decides to adopt the epoxy coating solution on the machine along with copper fins. With the concerted efforts of various departments of the company, it overcomes several difficulties and finally completes the smooth delivery of 30 outdoor units with copper fins.
The outdoor units of this project belong to the Hi-FLEXi S Series family, which have as advantages a wide range of capacities, high energy efficiency, good stability and wide adaptability. With the premise of meeting the requirements of customer comfort, savings on initial investment and low operating costs for customers.
For now, these systems are already in operation. The successful delivery of this project in Dos Bocas reflects the strong technical support capacity we have at Hisense HVAC, as well as the research and development capacity of the Hisense HVAC factory.
