Project Overview:
The cold storage facility is divided into six floors: one underground floor (high-temperature cold storage) and five above-ground floors (low-temperature cold storage), with two rooms on each floor. The high-temperature cold storage has a total design capacity of approximately 3000 tons. The low-temperature cold storage has a total design capacity of approximately 17000 tons.
Equipment Plan:
The low-temperature storage uses two sets of YBLD3-125J Bitzer low-temperature screw full-liquid parallel units with 10m³ barrel pumps, while the high-temperature storage uses one set of YBHZ6-40 piston parallel unit;
The low-temperature storage evaporator uses an aluminum finned tube evaporator with hot gas defrost, while the high-temperature storage uses six GEA air coolers; with water defrost;
Advantages of the Plan:
1. Uses Bitzer screw and piston parallel units; each compressor has multi-stage energy regulation, and the economizer uses a flash tank, effectively improving the equipment's energy efficiency ratio. PLC control can be linked with the terminal and has remote control functionality.
2. Achieves full-liquid evaporation in the evaporator, resulting in higher evaporation heat transfer efficiency and better cooling effect;
3. Utilizing the mechanical action of the refrigerant pump can overcome some resistance losses in the system, enabling long-distance liquid supply;
4. Achieves hot gas defrost, significantly reducing the energy consumption of traditional electric heating defrost methods.
