Dalian Ruixue Freezer Co., LTD. (formerly Dalian No. 2 Freezer Factory) was founded in 1953, was originally a national secondary enterprise, is a research, development, production, sales and installation services as one of the refrigeration equipment and petrochemical products manufacturing company。
According to the cold storage Design Code 2021, there are four antifreeze methods for the cold storage floor, including natural ventilation, mechanical ventilation, overhead layer design and antifreeze heating pipe (this scheme is omitted, Sheron freezing note).。First, the ground natural ventilation: the use of natural ventilation of the ground anti-freezing design should meet the following requirements: 1, the two ends of the natural ventilation pipe should be straight through, and slope to the outside。The total length of the straight pipe should not be greater than 30 meters, and the length under the ground of the cold room should not be greater than 24 meters。
New refrigeration enterprises need to carry out three simultaneous design, acceptance, in the early stage of the project, transformation enterprises need to consult the local emergency management bureau to confirm this requirement or rectification according to the requirements。Three simultaneous safety assessment projects mainly include three aspects: 1. The production and operation unit shall entrust the design unit with corresponding qualifications to design the safety facilities of the construction project at the same time, organize the review, and form a written report for reference
Use and maintenance: 1. Preparation before driving: (1) Check the three-phase power cord and external ground wire。(2) Open the small cover at the back of the unit, send power instantly, and check whether the motor steering is consistent with the marked steering of the pump body。It is strictly prohibited to run in reverse, and the operation of broken liquid shall not exceed 5 seconds。(3) Open the pump suction valve before starting, so that the whole unit is filled with ammonia fluorine liquid。2, driving: (1) Open the exhaust valve and exhaust small valve, pay attention to observe the outlet pressure gauge, adjust the working pressure。(2) During driving, pay attention to voltage and current
Refrigeration system valves are common ammonia refrigerant valves, freon refrigerant valves: globe valves (including surface valves), throttle valves, check valves, solenoid valves, liquid level float valves, automatic bypass valves, safety valves, etc。Special attention in the installation and use of ammonia valves The selection of ammonia (fluorine) refrigeration system installation valves should be determined according to the design documents or use conditions (working pressure, working temperature, etc.) requirements。Before installation, carefully check whether the mark is consistent with the use requirements;Check whether the packing is compressed, should ensure the sealing of the packing, but...

Cold storage dehumidifier is often used in fruit and vegetable storage and vegetable air conditioning storage, high temperature storage cold storage, medical storage cold storage, ice skating rink, ski resort and other relatively low temperature environment。Among them, the humidity of pharmaceutical cold storage and food cold storage will affect the normal use and safety of food and drugs。In the relatively strict cold storage or skating rink, it is generally necessary to configure dehumidifier。Low temperature environment dehumidifier selection: Generally common dehumidifiers are ordinary dehumidifier, low temperature dehumidifier and rotary dehumidifier (other models are omitted)。Among them, ordinary dehumidification
