5,000 m³ Chili Cold Storage Project in Zunyi, Guizhou, China

Project Overview

In May 2024, Zhuohao Agricultural Technology Co., Ltd. (Guizhou, China) completed the construction of a 5,000 m³ chili cold storage facility. The project consisted of three independent cold rooms, designed to maintain storage temperatures between -5°C and +8°C, meeting strict energy efficiency and URS (User Requirement Specification) standards.

Engineered Solution

1. Intelligent Refrigeration System

Core Components:
- 3 × Emerson Copeland™ ZPS25KQE scroll compressors (25HP each)
- Eco-friendly R448A refrigerant (GWP=1273)
- Danfoss™ electronic expansion valves
Energy Optimization:
- Variable frequency drives (VFD) reduce compressor cycling losses
- Hot gas bypass defrost cuts 40% energy vs electric defrost

2. Insulation & Panel System
