Design and installation of cold storage

Cold storage is a facility for storing and preserving low-temperature items such as food and medicine. In food industry, pharmaceutical industry and other related industries, refrigeration is more and more widely used. This paper will introduce the design and installation of cold storage.

First, the cold storage design

1, cold storage type

Cold storage is generally divided into mechanical refrigeration, absorption and air conditioning. Mechanical refrigeration refers to the use of compressor and other mechanical equipment refrigeration, low cost, suitable for small commercial places. Absorption type is to absorb water with absorbent, and then release heat for refrigeration. Modified atmosphere refers to the preservation effect by controlling the gas composition and proportion in the air.

2. Temperature and humidity of cold storage

The temperature and humidity of cold storage are one of the key factors in the design of cold storage. Generally speaking, the temperature of cold storage is between-18℃ and 5℃, and the humidity is about 70%. Different articles need different temperature and humidity, so these factors need to be considered in the design of cold storage.

3, the capacity of the cold storage

The capacity of cold storage needs to be determined according to the demand. Generally speaking, the capacity of cold storage should be enough to store all the items that need to be stored, and the future expansion needs should also be considered.

4, the structure and details of the cold storage

The structure and details of the cold storage also need to be considered. For example, the door of the cold storage needs thermal insulation, and it is also necessary to consider whether it is necessary to install fire prevention and anti-theft facilities. In addition, the internal structure of the cold storage should be reasonable, which is convenient for storing and taking out items.

Second, the cold storage installation

1, cold storage construction permit

Before installing the cold storage, you need to apply for a cold storage construction permit. This permit is issued by the General Administration of Quality Supervision, Inspection and Quarantine, and it needs to provide some necessary data and information, such as building plan, design scheme, equipment parameters and so on.

2, equipment procurement and installation

The equipment of cold storage includes refrigeration equipment, insulation materials, doors, etc. These devices need to be purchased and installed according to the design scheme. Refrigeration equipment is the core of the whole cold storage, and it needs to be selected and arranged according to the design scheme.

3. Cold storage insulation

Thermal insulation is the core of cold storage design and installation. The selection and installation of thermal insulation materials shall comply with relevant national standards and regulations. The quality and thickness of thermal insulation materials determine the thermal insulation effect of cold storage.

4. Ventilation and dehumidification of cold storage

Cold storage needs ventilation and dehumidification to keep the humidity and quality in the air. Therefore, it is necessary to install corresponding ventilation equipment and dehumidification equipment according to the design scheme.

5, cold storage maintenance and maintenance

The maintenance of cold storage is very important, which can prolong the service life of cold storage and maintain its performance. Regularly clean, maintain and inspect the refrigeration equipment, thermal insulation materials, ventilation equipment and dehumidification equipment.

The design and installation of cold storage need to consider many factors, including temperature and humidity, capacity, structure and details. Before installation, you need to apply for a construction permit, and purchase installation equipment according to the design scheme. After installation, the maintenance of cold storage is also very important.
