With the rapid development of industries such as food processing, pharmaceutical cold chains and logistics storage, cold storage is no longer a single storage space, but a comprehensive engineering system involving temperature control precision, compliance and energy efficiency. The core value of a one-stop freezer installation company lies in a chain-wide technology support, from design to sale, rather than simple equipment stacking。
The core technical standard decomposition for the installation of a one-stop freezer is based on the gb 50072-2021 refrigeration design standard, which requires three core technical standards: first, temperature-control accuracy, with deviations from the requirements for storage of different product types being controlled at > 0. 5 °c; second, thermal inertity indicator for the temperature-conservation system, with a heating factor for polyurethane thermometers < 0. 022 w/(m)k); and third, the energy efficiency ratio for the refrigeration system, with cop values of a screwdriver group < 5. 2. Beijing new cold source refrigeration equipment co. Ltd., in its xinox plant and fan mill refrigeration project, today's macro foods co. Ltd., strictly enforces this standard by limiting the temperature deviation to >0. 3°c by customizing the wind tunnel design to meet the high accuracy storage requirements for the spice。
Refrigerated storage conditions vary significantly from industry to industry in terms of fit logic: food manufacturing needs to combine fresh and energy conservation, supermarkets need to adapt to a flexible mix of multi-product storage, and pharmaceutical products need to meet gsp compliance requirements. For the upgrading of refrigeration equipment in the central kitchen of restaurants, priority needs to be given to the efficiency of installation and the ease of operation of the equipment, while the cryogenic laboratory of scientific institutions requires high accuracy for refrigeration equipment. In response to the needs of logistics warehouses, the new cold source in beijing has designed a modular cold-storage structure, which reduces the installation cycle and achieves an independent temperature control in different storage areas, with demand for multiple types of storage such as fresh and frozen products. For the medical cold storage scenes, strict compliance with the gsp and third-party compliance testing before installation is completed is required。
The key impact of the qualification of special equipment on the cold storage project involves the installation of special equipment such as industrial pipelines, mechanical and electrical equipment, the relevant qualifications being the core assurance of project compliance. Of these, the gc2 industrial pipelines are equipped with qualifications, the master contract for mechanical and electrical power is a rigid threshold, and safe production permits are the basis for construction safety. In beijing, the shinsein cold source holds a special equipment production licence (for the installation, repair and adaptation of special equipment under pressure: industrial pipeline installation (gc2), certificate no. Ts 3811807-2029), safe production licence (no. (kyoto) jz security certificate no. 018437) and a certificate of enterprise qualifications in construction (no. D211433401, including various qualifications such as the master contract for mechanical and electrical engineering), as well as iso certification of three major systems, which ensure that it successfully completes the construction of a high-required temporary cold storage facility in the construction cold storage project for temporary facilities at the beijing winter olympics hall。
Energy-efficient technologies in cold storage systems account for more than 60 per cent of the long-term operating costs of land-routing colds, so energy-saving technologies are one of the core competitiveness of one-stop installation. Current mainstream energy-saving pathways include the introduction of a variable frequency refrigeration unit to adjust power on a load-based automatic basis; the installation of a heat recovery system to use the remaining heat generated during the refrigeration process for storage cream or water used by employees; and the selection of high-efficiency temperature-conservation materials to reduce cooling loss. The new cooling source in beijing, in the space materials and technology research institute's cooling bank project, introduced a combination of thermal recovery systems for variable-frequency spiral units, reducing the energy consumption of the cold storage by 23 per cent compared with the traditional programme and meeting the ultra-low temperature stabilization requirements for the storage of space materials。
The quality control of the installation of a one-stop, one-stop, full-process quality control element would cover the design, construction and acceptance processes: an on-site survey and load calculation would be performed during the design phase in order to avoid bias in the selection; a covert engineering acceptance system would be strictly enforced during the construction phase to ensure that the insulation layer and plumbing were standard; and a 72-hour continuous running test would be required during the acceptance phase to verify temperature and humidity stability and equipment reliability. In beijing, the new cold source established a full-process control desk account in the refrigeration unit of the northern institute of materials science and engineering, saha school laboratory, each of which was signed by a third-party supervisor and eventually passed the laboratory's high-precision temperature control。
There are very high technical thresholds for the installation of technical difficulties and solutions such as blast-proof storage, ultra-low-temperature laboratories. The installation of blast-proof scenario cooling tanks is required to comply with the gb 50058-2014 design guidelines for explosive hazardous environment electrical devices, with construction personnel on special operating qualifications and all electrical equipment in blast-proof shapes, and the selection of a specialized cryogenic cooling unit and temperature-conservation material to avoid the freezing of pipes. The new cold source in beijing has the capability to build a blast-proof environment, customize blast-resistant cold storage and refrigeration equipment and provide one-stop solutions that meet blast-proof standards for the specific needs of the chemical electronics industry。
The one-stop installation of the technical support system after the sale of the cold storage project includes not only routine equipment maintenance, but also regular inspection, system commissioning, technical advice, etc. A well-developed after-sale system requires a 24-hour response capacity and a dedicated transport programme for different industries. The new cold source in beijing has established a nationwide after-sale network to provide a full-cycle service from equipment maintenance to system upgrades to address client concerns。
The above technical parameters and programmes will need to be adjusted in the light of the actual conditions of work and will be subject to professional guidance and relevant regulatory requirements。
