HVAC / Heat Pump Structural Design - Full unit structure design (indoor / outdoor / integrated units) - Refrigeration system integration (compressor, heat exchangers, piping layout) - Noise reduction optimization (airflow vs noise balance) - Waterproofing, anti-vibration, piping stress & reliability design - Electrical enclosure safety & system integration 2. Industrial Heat Pump & HVAC Design - Industrial-grade heat pump system design - Industrial HVAC equipment (high reliability / long lifespan / harsh environments) - Custom non-standard equipment structure design 3. Manufacturing-Oriented Engineering (DFM / DFA) - Design for Manufacturing (DFM) - Design for Assembly (DFA) - Cost optimization - Mold feasibility analysis (plastic / sheet metal) Service Scope Heat Pump Products: Residential heat pumps (Monoblock / Split), modular systems, integrated water systems / hydraulic modules Air Conditioning & Light Commercial HVAC: Indoor / outdoor unit structure design, PTAC / window AC / portable AC, heat exchanger design (evaporator / condenser), electrical cabinet design Industrial & Custom Equipment: Industrial air conditioning, custom equipment structure design Additional Design Services: Sheet metal design, plastic part design, HVAC piping optimization, product upgrade & partial redesign Mold & Manufacturing Support: Mold design review (DFM), injection molding / sheet metal process optimization, supplier sourcing & factory coordination Cross-Functional Collaboration: Work with thermal engineers (refrigeration system optimization), work with electrical engineers (control system integration), support full system-level product development China-Based Engineering Support: Reliable supplier sourcing, on-site or remote production support, fast issue resolution during prototyping and mass production What I Need From You (Before Starting) To ensure an efficient project process, please provide as much as possible: 1. Basic Product Information: - System diagram / schematic - Sketch / concept / idea - Reference images or benchmark products 2. Certification & Market Requirements: - Target certifications (CE / UL / Keymark / TÜV, etc.) - Target market (Europe / North America, etc.) 3. Production Information: - Target production volume (prototype / small batch / mass production) - Whether you already have a factory or supply chain 4. Design & Manufacturing Preferences: - Material preference (plastic / sheet metal / hybrid) - Special requirements (cost target / appearance / size constraints, etc.) Even if you only have a rough idea or simple sketch, feel free to contact me. I can help you refine the concept and bring your product to life. My Commitment ✔ On-time delivery ✔ Design compliant with international standards (CE / UL, etc.) ✔ Production-ready, manufacturable design ✔ Free initial technical consultation ✔ Reliable and efficient communication
