How to install large-scale cold storage refrigeration equipment
The cold storage is mainly used as a constant temperature storage air-conditioning equipment for food, dairy products, meat, aquatic products, etc. The cold storage is a kind of low-temperature cold storage and also a kind of refrigeration equipment. Ordinary cold storage is mostly refrigerated by a refrigerator, using liquid with a very low vaporization temperature as a coolant to evaporate under low pressure and mechanically controlled conditions, and absorb the heat in the storage to achieve the purpose of cooling. How to install large-scale cold storage refrigeration equipment?
1. Preparations. The preparatory work includes drawing up a cold storage installation project plan, preparing the construction site and construction materials. Various materials for cold storage construction are formulated according to customer needs. After drawing up the construction plan, sort out the construction site that meets the requirements, transport all the installation data to the construction site, check the quality and model of the data, and start to install the cold storage after confirming that it is correct.
2, device library body. Today's small and medium-sized cold storages in China are basically combined cold storages assembled with warehouse boards, and most large-scale cold storages are civil cold storages. According to the project plan, assemble or construct the cold storage body and install the door. The library body is required to be flat, tight and firm, without hollow feeling, and meet the engineering requirements of airtightness, moisture-proof, anti-freezing, and load-bearing; the library door should be opened and closed sensitively and has good airtightness.
3. Install refrigeration equipment. The refrigeration system of the cold storage includes an evaporator inside the storage and a unit outside the storage. Therefore, the equipment must be in accordance with the construction standards, and the equipment must be installed in a position that meets the requirements, and there are corresponding maintenance measures.
4. Install an electric control system. The electric control system of the cold storage includes some electric equipment such as electric control box, electric door, and interior lighting. The cold storage power request is a stable three-phase four-wire (380v), and an independent power supply or a backup power supply can be used as needed. The circuit should be discharged reasonably and have corresponding maintenance measures.
5. Connect the refrigeration system. Wires, copper pipes, etc. should be used to connect cold storage refrigeration units, electrical control systems and other components. The connection and closing channels should be tightly connected, and there should be corresponding heat preservation and maintenance measures.
6. Install other equipment. Because of the different types of goods stored in cold storage and the use of different methods, different cold storage will request additional equipment, such as humidifiers, shelves, conveyor belts and other equipment and equipment that are convenient for users to use cold storage.
7. Debug cold storage. After all the components of the cold storage are connected and connected, the cold storage can be started to stop debugging. Adjust the value of the cold storage according to the demand, test the cold storage, the cold storage can reach the predetermined temperature, the cooling rate and the cold storage are operating normally, the cold storage can be shipped and used.
