Construction of high and low temperature cold storage, design and installation of variable temperature storage, support for non-standard customization

1： What is a variable temperature cold storage

Variable temperature cold storage is a type of cold storage or multiple cold storage units that can be adjusted and selected for safe operation within multiple temperature ranges. It can meet the daily storage requirements of customers for different goods in a cold storage. The specific classification is as follows:

（1） One machine, one warehouse, variable temperature warehouse

One machine, one warehouse is commonly referred to as one refrigeration equipment corresponding to one cold storage, which meets the storage requirements of customers for different goods under high or low temperature conditions. This type of variable temperature warehouse is generally a small cold storage.

（2） One machine, multiple storage, variable temperature storage

One machine with multiple storage facilities refers to one refrigeration equipment corresponding to multiple cold storage facilities, each of which has adjustable storage temperatures of high or low temperature and can simultaneously meet the storage requirements of customers for different goods replacement. This type of variable temperature warehouse is generally suitable for large cold storage.

Cold storage installation is a complex and systematic project, which can be mainly divided into the following steps:Construction of high and low temperature cold storage, design and installation of variable temperature storage, support for non-standard customization

1、 Preparation work

1. Material PreparationAccording to the design drawings and actual needs of the cold storage, prepare the required materials such as cold storage panels, doors, refrigeration units, refrigeration evaporators (air coolers or exhaust pipes), microcomputer temperature control boxes, expansion valves, connecting copper pipes, cable control lines, storage lights, sealant, etc.

2. Preparation of construction siteEnsure that the construction site is flat, clean, and equipped with necessary construction conditions such as power and water sources.

2、 Installation of storage board

1. Ground treatmentEnsure the ground is level and level any uneven areas.

2. Warehouse board assemblyAssemble the cold storage panels according to the installation sequence (such as floor, rear wall, rear wall, front wall, and finally top plate), use locking hooks and sealant to fix and seal the panels.

3. Installation of drainage systemInstall a drainage system under the floor and evaporator to ensure that there is no accumulated water inside the cold storage.

3、 Installation of refrigeration equipment

1. Installation of air coolerAccording to the internal structure and air circulation requirements of the cold storage, choose a suitable location to install the air cooler and ensure a certain distance from the storage panel.

2. Installation of refrigeration unitSelect the appropriate type of refrigeration unit (such as fully enclosed refrigeration unit for small cold storage and semi enclosed refrigeration unit for medium and large cold storage) based on the scale and refrigeration needs of the cold storage, and install it in the appropriate location.

3. Installation of oil separatorInstall an oil separator on the refrigeration unit and add an appropriate amount of engine oil. If the preset temperature of the cold storage is below -15 ℃, refrigeration oil should also be added.

4、 Installation of refrigeration pipelines

1. Pipeline designDesign a reasonable pipeline layout and diameter according to the requirements of the refrigeration system.

2. Pipeline installationAccording to the design drawings, connect the refrigeration pipes to various equipment and ensure that a certain safe distance is maintained between the pipes.

3. pipe insulationUse insulation materials to insulate the pipeline and reduce cold energy loss.

5、 Installation of electronic control system

1. Wire layingAccording to the drawing requirements, lay the wires and fix them with binding wires.

2. Manufacturing and installation of electrical control boxStrictly manufacture the electrical control box according to the drawing requirements and install it in the appropriate position.

3. system debuggingAfter the installation of the electronic control system, conduct no-load experiments and system debugging to ensure the normal operation of all equipment.

6、 Cold storage debugging and acceptance

1. Confirmation of power supply voltageBefore debugging the cold storage, confirm whether the power supply voltage is normal.

2. Equipment opening and closing inspectionCheck the opening and closing status of each device to ensure there are no abnormalities.

3. Refrigerant injectionInject refrigerant into the storage tank and operate the compressor.

4. Temperature setting and detectionSet the temperature of the cold storage and check whether the functions of each part are normal.

5. Customer AcceptanceAfter the cold storage is debugged, invite the customer to conduct acceptance and sign for confirmation.

7、 Precautions

1. Safe constructionDuring the construction process, strictly adhere to safety operating procedures to ensure the personal safety of construction personnel.

2. quality controlAfter each construction phase is completed, quality inspections are conducted to ensure that the construction quality meets the design requirements.

3. maintenanceAfter the installation of the cold storage is completed, provide the user with a maintenance manual and inform them how to carry out daily maintenance and upkeep.

In summary, cold storage installation is a complex and systematic project that requires professional personnel to operate. During the installation process, construction should be strictly carried out in accordance with the design drawings and construction specifications to ensure the quality and safety of the cold storage.Construction of high and low temperature cold storage, design and installation of variable temperature storage, support for non-standard customization
