Acceptance standards after the cold storage design and installation are completed

Acceptance standards after the cold storage design and installation are completed

A newly built cold storage, when it's time for acceptance, it will definitely be anxious. How can it be accepted to ensure quality and quantity? The editor of okmarts.com will briefly introduce it below.

　　 1. Cold storage design and installation acceptance standard

　　1. The storage board is tightly installed. The metal plates inside and outside the storage surface must not be connected to prevent the formation of cold bridges.

　　2. Cold storage design The sealant between the cold storage plates is evenly spread. The warehouse door is installed straight and tightly closed and opens freely.

　　3. The color of the refrigeration compressor unit is the same, the layout is reasonable, and the unit installation of each model is consistent.

　　4. The pipe diameter of each component of the refrigeration system should be selected to meet the design requirements.

　　 5. The installation location of the unit should be convenient for observation, maintenance and adjustment.

　　 6. The expansion valve bulb should be kept warm.

　　7. The installation position of the fan, expansion valve and filter should be convenient for maintenance.

　　 8. The air return pipe of the air cooler should have a slope, the outlet of the fan should be equipped with an oil return bend, and the choice of the pipeline direction should consider the resistance and beauty in the pipeline.

9. When the compressor is running, check the oil level, base vibration, running sound, suction temperature, exhaust temperature, motor temperature, crankcase temperature, high and low pressure, operating current, air outlet direction, air cooler and expansion valve The effectiveness of frost condition, pressure protection and motor thermal overload protection.

　　 10. Whether the design of computer temperature control data meets the requirements of use.

　　11. Whether the electrical control components are sensitive, the electrical coils should not be heated and there should be humming, the wire contacts should be strong, and the wire skin should not exceed 40 degrees.

　　12. The entire system must be grounded or connected to zero.

　　13. Line pipes and refrigeration pipes should be horizontal and vertical, and should not be crossed and uneven. A certain distance should be left, and all pipelines should be fixed with metal clips, and there should be no resonance and mutual friction.

　　14. The entire project shall be constructed according to the design.

　　 15. The entire project and construction environment are clean and tidy.

　　 2. Instructions for using cold storage

　　 1. The cold storage refrigeration equipment must be managed by a special person, and the management personnel should have certain professional knowledge and skilled operation techniques.

　　2, refrigeration equipment operators should strictly follow the product instructions to operate the equipment.

　　3. The room where the refrigeration equipment is placed must have a good ventilating environment. The refrigeration equipment should not be placed with the heat source, and the room should be kept clean and dry.

　　4. The daily purchase quantity of cold storage shall comply with the following regulations:

　　4.1. Freezer and cold storage should be purchased according to design capacity.

　　4.2. The daily purchase volume of the fresh-keeping warehouse for storing fruits, vegetables and fresh eggs shall not exceed 10% of the total capacity.

　　4.3. The volume of frozen meat transferred into the cold storage shall not exceed 30% of the storage capacity. The incoming volume of chilled meat shall not exceed 10% of the storage capacity.

　　4.4. The quantity of fresh meat purchased in cold storage shall not exceed 5% of the total capacity.

　　 5. Do not adjust the temperature controller, pressure relay, defrost interval and other values ​​casually.

　　6. ​​Do not open the warehouse door frequently, especially when new goods are just put into the warehouse. The number of daily openings should be controlled within 10 times, and the door should be closed when entering and leaving the warehouse.

　　7. In the daily operation of refrigeration equipment, check the suction and discharge temperature and the operation of the condenser fan frequently. Check the oil pressure, oil temperature and oil level, pay attention to the temperature rise of the machine and whether there is any abnormal sound. The condenser fins should be cleaned regularly, and care should be taken not to enter the electrical components when cleaning.

　　 8. Do not disassemble the machine casually.

　　 9. Cargo in and out should be handled gently. Do not pry the cargo with hard objects such as iron to avoid damage to the warehouse.

　　 10. When the refrigeration water circulation system is not in use in winter, the circulating water in the system must be emptied to prevent equipment damage from freezing.
