A New Member of "Good Cold Storages": Phase II for a Well-Known Brand in Langfang
Haier Carrier has always been committed to creating "good cold storage" for customers, which are projects with satisfactory design, reliable construction, and worry-free operation. Recently, the second phase of a cold storage project for a well-known brand in Langfang was fully delivered. This cold storage is the first five-star cold chain distribution center in Langfang and North China, and also one of the largest and most modernized cold storages in the Beijing-Tianjin-Hebei region and North China.
It is worth mentioning that the "Haier Carrier Intelligent Management System" (hereinafter referred to as " Intelligent System") has effectively improved the quality and progress of the project. The visualization of the entire process management makes it possible for the operation to be worry-free.
Project brief
· Total area: 12,000 m2
· Project size: low-temperature storage area - 8,500 m2 , medium-temperature storage area - 3,500 m2
· Total construction time: 170 days
· Completion time: Nov 2023
Project Features:
1. Highly integrated refrigeration system:
o Requires the oil balance of the racks between high- and low-pressure stages, and normal start and stop of each unit under low-load conditions.
o Three temperature zones of -25°C, -18°C, and 1-7°C share one refrigeration system, which makes the system more refined.
2. Long refrigeration pipeline distance: Many oil return points with high requirements
3. Interlocking work of various disciplines: Construction of various disciplines such as civil engineering, fire protection, HVAC, insulation, and refrigeration is carried out at the same time. There are many intersections and strong connections. They’ve all cooperated closely, communicating and coordinating progress and construction locations in a timely manner.
Haier Carrier Solution Highlights:
Two-stage coupling refrigeration system, customized to meet the needs of multiple working conditions and temperature zones:
a. A two-stage system with multiple racks. The high-pressure section takes into account the two-stage coupling of the high-pressure stage and the high-temperature storage.
b. A two-stage refrigeration system with once throttling and intermediate full cooling is used to reduce the low-pressure stage discharge temperature, overcool of the high-pressure stage liquid, and reduce flashing gas. The operating efficiency is higher than that of the traditional systems and is more energy efficient.
c. Multiple working conditions of -25°C/-18°C/1-7°C share one refrigeration system, which makes the system more refined.
Switching between two temperature zones: Reduces the number of pipes and valves, optimizes the system, and facilitates operation and maintenance.
Multiple oil return methods: U tube, E-jector, shell and tube separator oil return, high- and low-pressure stage oil separator automatic oil balance, and automatic oil balance by high- and low-pressure stage oil pump .
Independent pipelines for multiple working conditions of -25°C/-18°C/1-7°C:
a. Each working condition runs independently without interfering each other.
b. The corresponding equipment is turned on for different working conditions.
c. Compressors between working conditions can be used as spares.
Last but not the least: The successful completion of this complex project with multiple disciplines working in parallel is mainly due to Haier Carrier's "Intelligent System".
a. The system integrates project bidding, design optimization, project management, and after-sales service.
b. It achieves accurate design, full-process construction control, and rapid response.
c. It makes personnel and material data digital and transparent, and safety and quality management systematized and visualized.
The two-stage system solution of Haier Carrier is more efficient and energy-saving and can meet the needs of various cold storages:
- Comprehensive solution team design customized project plan based on customer needs
- A single rack can meet needs of different temperatures and adjust temperature faster and more effective
- Disproportionate parallel rack can be set up for different sizes of cold storage to achieve more precise match
- Increases system performance by 15% - 20% compared with traditional single rack
It is precisely with our high-efficiency cold storage system solution that we can ensure the cold chain temperature and freshness requirements of multiple industries, such as manufacturing, fast-moving consumer goods, chain catering, fruits, potato products, and dairy products, which can effectively guarantee everyone's daily meals.
