What are the core components of a controlled atmosphere cold storage? What are their functions?

Controlled atmosphere cold storage is a modern and efficient type of cold storage, which has significant advantages in preservation and storage. However, its cost is also relatively high. In the Chongqing area, the cost of constructing a controlled air cold storage is approximately 1200 yuan/square meter. Of course, the smaller the scale, the higher the cost per square meter.

Construction and operating principle of air-conditioned cold storage

The air-conditioned cold storage mainly consists of three parts: insulation storage body, refrigeration equipment, and air-conditioned equipment.

• Insulation storage bodyIt is the basic structure of the cold storage, using polyurethane insulation board for insulation treatment to maintain the low-temperature environment inside the cold storage.

• Refrigeration equipmentIt is the core component that controls the temperature inside the warehouse, reducing the temperature inside the warehouse through refrigerant circulation.

• Air conditioning equipmentIt is a key part of achieving gas regulation, including equipment such as carbon dioxide removal machines and nitrogen generators, to control the concentration of oxygen, carbon dioxide, and other gases in the warehouse.

Cost of constructing a controlled atmosphere cold storage in Chongqing

Taking a 100 square meter air-conditioned cold storage as an example, the cost is approximately 1200 yuan/square meter. The specific costs include:

• Cost of insulation materialsAbout 30% -40% of the total cost.

• Refrigeration equipment costsAbout 20% -30% of the total cost.

• Cost of air conditioning equipmentAbout 10% -20% of the total cost.

• Other related expensesAbout 10% -20% of the total cost.

Key points in the construction process of air-conditioned cold storage

1. Choose appropriate insulation materials

The selection of insulation materials is crucial for the construction of air-conditioned cold storage. Common insulation materials include polyurethane insulation board, EPS insulation board, etc. When selecting insulation materials, not only should their insulation effect be considered, but also factors such as durability and fire resistance should be considered.

1. Choose the appropriate refrigeration equipment

Refrigeration equipment is the core component of air-conditioned cold storage, and its selection and configuration directly affect the operational efficiency and energy consumption of the entire cold storage. The selection of refrigeration equipment should be based on actual needs, and well-known brands and professional manufacturers should be selected for customization.

1. Choose appropriate air conditioning equipment

Gas regulation equipment is a key equipment for achieving gas regulation, mainly including carbon dioxide removal machines, nitrogen generation machines, etc. The high cost of purchasing and installing these equipment is one of the main factors affecting the cost of air-conditioned cold storage. In addition, the debugging and installation of air conditioning equipment is also of utmost importance, and it needs to be operated under the premise of good sealing to ensure its normal operation and play its due role.

The cost of constructing a controlled atmosphere cold storage in Chongqing varies due to various factors. Generally speaking, the smaller the scale, the higher the cost per square meter. When constructing air-conditioned cold storage, it is necessary to fully consider various factors, conduct comprehensive evaluation and reasonable planning to ensure the optimal investment effect.
