🏆Do you want to design a freezing system? Or air condition a room?🏆 Hello! I'm Javier Sánchez, a Mechanical Engineer with 16 years of solid experience in the design and optimization of industrial refrigeration and HVAC (heating, ventilation, and air conditioning) systems. I have had the privilege of working in various industries: food, beverages, agribusiness, and fishing, among others. This background has given me great flexibility and broad judgment to solve the unique challenges each project presents, from conception to implementation. Do you need to design a complex freezing system or efficiently air-condition an industrial space? I am here to help you. 🌟 Design of Ultra-Low Temperature Systems (-95°C / -139°F) 🌟 My experience focuses on designing 2 and 3-stage cascade systems to achieve ultra-low temperatures, using refrigerants such as R-23, R508B, R507, R134A, R404. Project deliverables: ✅ Thermal load balance. ✅ Step-by-step installation guide. ✅ Pipe calculation report. ✅ Control logic. ✅ Material takeoff. ✅ Preventive maintenance plan. Drawings and modeling: ✅ 3D design in SolidWorks. ✅ Piping drawings. ✅ Heat exchanger design in Aspen Hysys, Aspen EDR, and HTRI. 🌟 Refrigeration System Design (Refrigerants: Ammonia, Freon, CO2) 🌟 ✅ P&ID design for cooling systems. ✅ Heat pump design. ✅ Freezing and preservation chambers (cold storage). ✅ RSW (Refrigerated Sea Water) system design for fish unloading. ✅ Ammonia freezing plant design. ✅ Optimal selection of heat exchangers (including plate heat exchangers), chillers, and other equipment. ✅ Chilled water systems for process. ✅ Selection of glycol (chilled water) recirculation pumps. ✅ Air conditioning of process rooms. 🌟 Services Offered in HVAC 🌟 ✅ HVAC system design for residential buildings, condominiums, shopping centers, and more. ✅ Equipment selection. ✅ Duct and pipe sizing. ✅ Grille and diffuser selection. ✅ Mechanical ventilation system design. ✅ Extractor and injector calculation. ✅ Technical file for license approval. ✅ Constant pressure systems for process rooms or stairs. ✅ Dust extraction systems. 💡 Additional Technical Support Areas 💡 Besides complete designs, I can offer specialized technical support in: 1. Computational Fluid Dynamics (CFD) modeling using Ansys Fluent. 2. Heat exchanger design with Aspen Hysys, EDR, or HTRI. 3. Advanced and detailed 3D modeling in SolidWorks. ✨ Why Choose Me Over Other Freelancers? ✨ The added value I offer goes beyond just design on paper. I have the judgment and practical experience from having built industrial plants from scratch, implementing and coordinating disciplines such as civil, mechanical, piping, refrigeration, structural, and electrical. This comprehensive vision allows me to anticipate potential interferences and harmonize my design efficiently with the rest of the project, avoiding setbacks and cost overruns during the construction phase. ✨ Remember: ✨ Modifying a drawing has minimal cost. Modifying what has already been built directly impacts the project's budget and schedule, besides causing inconvenience. Therefore, it is essential to choose correctly the person who will carry out your design. Good design engineering is the best investment! I enjoy applying my creativity, experience, and knowledge to provide the best solutions for my clients. I am drawn to complex and challenging applications, and my approach to tackling difficult jobs prepares me for almost any task within my areas of expertise. Thank you for visiting my profile! 😁 I look forward to hearing from you soon and collaborating on your next project. 🔜 #mechanicalengineering #hvac #refrigeration #ammonia #freon #co2 #solidworks #aspenhysys #aspenedr #htri #ansysfluent #fluent #cfd #autocad #coolselector #heattransfer #heatexchanger #plateheatexchanger #industrialdesign #optimization #energyefficiency #freelancer #upwork #coldstorage #chamberstorage #chiller #modeling
