Project Overview
Project Address: Wuli Road, Liangjiang New Area, Chongqing
Project Content: One freezer and one cold storage supporting a food processing workshop
Service Scope: Cold storage design, panel production, unit configuration, installation and commissioning

Cold Storage Electric Control System (Independent temperature control for freezer and cold storage)
Project Background
The client is a food processing enterprise located in Liangjiang New Area, Chongqing. The workshop needs to meet two temperature zone requirements simultaneously: raw materials such as vegetables require cold storage for preservation, while finished and semi-finished products need freezing storage. Using a shared system would not only cause temperature interference but also lead to odor cross-contamination and energy waste.
Based on the client’s processing flow and site conditions, our technical team designed a dual independent system — the freezer and cold storage are each equipped with independent refrigeration units and electric control systems, operating separately without mutual interference.
Solution Configuration
Warehouse Structure
· Polyurethane double-sided color steel plate assembled warehouse body
· Fully enclosed insulation for floor, ceiling and four walls
· Warehouse panel joints locked by eccentric hooks, ensuring excellent sealing performance

Ceiling-mounted air cooler and insulated ducts in warehouse
Refrigeration System
· Two sets of integrated refrigeration units operating independently, corresponding to the freezer and cold storage respectively
· Outdoor units concentrated on the roof platform with sufficient heat dissipation space
· Ceiling-mounted air coolers in the warehouse, with insulated ducts for air supply

Integrated condensing unit (installed beside the vegetable processing workshop)
Control System
· Two independent wall-mounted electric control boxes with digital temperature display
· Independent start/stop and alarm functions; failure of one warehouse does not affect the operation of the other
· Control panels facing the aisle, facilitating daily inspection and parameter adjustment
Door & Details
· Stainless steel door frame with moisture-proof sealing strip
· Foam sealing treatment for pipe penetration through walls, reducing cold bridges and cold leakage

Outdoor refrigeration unit on roof platform
Project Highlights
· Dual independent temperature control: Separate operation for freezer and cold storage, no temperature interference, avoiding odor cross-contamination
· Integrated units: Small footprint, fast installation, suitable for retrofitting existing workshops
· Wall-mounted electric control boxes: No floor space occupation in the workshop, easy operation and maintenance
· Outdoor units concentrated on roof: Good heat dissipation, unit noise does not affect the workshop working environment
Delivery Results
The project completed installation and commissioning for the client on schedule. Both warehouses reached the designed temperature requirements, operated stably, and met the continuous production needs of the food processing workshop.
