Anhui professional cold storage installation details and key issues in cold storage engineering design

Zirun Cold Storage Construction Specifications: 1. Introduction Editing
The construction of a warehouse that uses cooling facilities and equipment to achieve suitable humidity and low temperature conditions, including the procurement of consumables and auxiliary materials for various cold storage equipment and facilities, the construction of warehouse boards, hoisting of internal and external machines, and laying connections The process of pipelines, pipeline insulation, drainage pipe installation, line erection and connection, installation of control systems, wiring of internal and external machine power cords and system debugging.
2. Basic process of cold storage construction
Manpower organization, arrival of machines and equipment, joint review of drawings and technical explanations, material procurement and entry, support and bracket production, warehouse splicing, partition wall perforation, drainage pipeline installation, support Rack installation, welding installation of main lines, main line insulation, branch pipe welding, pipeline insulation, control line laying, indoor unit fixation and interface, outdoor unit hanger fixation and interface, piping system blowing, pressure test, drain pipe leak test , system vacuuming, system fluorine filling, test machine debugging, operation, system final arrangement and acceptance.
3. Key points in cold storage construction
Before constructing the cold storage, open the lifting screw holes first. The last two holes should be trimmed to prevent the quick opening from leaving hidden dangers. The back side of the evaporator with self-equipped drainage pipe and the vertical plate are positioned so that the evaporator drainage hole is perpendicular to the pre-installed drainage hole on the vertical plate. The height difference between the two is as frozen In the cold storage, the drain pipe is equipped with a drainage electric heating wire. The heating part of the drainage electric heating wire in the cold storage can only extend to the inside of the storage board. The drainage pipe is internally insulated. No electric heating wire is required for refrigeration. Everything else is the same.
Reasonable connection installations such as cold storage evaporators, radiators, copper tubes, temperature controllers, wires, cold storage hosts, etc. can make the cold storage unit and refrigeration system work safely and stably. The closer the cold storage unit is to the evaporator, the better. The heat dissipation is good. If it is moved outside, a rain shelter needs to be installed. Anti-vibration gaskets need to be installed at the four corners of the cold storage unit. The installation is level and firm and is not easily touched by people. It is best to install the unit in the upper part of the cold storage. The closer the radiator is to the cold storage unit, the better. The radiator installation position has the best heat dissipation environment. The air suction port cannot face the air outlets of other equipment, especially oily gases. The air outlets cannot be short-circuited or face other windows (especially windows of residents) and equipment. The air suction outlet should be high from the ground. Level and firm. All copper pipes need to be wrapped in insulation tubes and wires in the same direction with air conditioning ties. Try to run straight pipelines and fix them in sections.
Corrugated hoses or wiring troughs need to be used for protection, and all wires should be tied with air conditioning ties. Try not to arrange the temperature display wires close to the wires. Because the condenser and evaporator of the cold storage construction unit are sealed in the factory, there should be pressure when opening, and you can check whether there is any leakage. The copper pipes leaving the factory should have dust sealing measures at both ends. Pay attention to them at all times during construction. Sealed to prevent water and dust from entering the tube, the condenser rrr cold storage host rrr evaporator, the copper tube is connected by welding, and the interface is firm and beautiful.
The wire diameter meets the requirements, and the wires are configured according to the performance of each electrical appliance. The joints are firm, and the pipes need to be maintained, which cannot be spared, and the power connections must be correct. The wires entering the evaporator junction box hole need to be sealed with silicone. If the light is connected to more than 3 electricity, a grounding wire is required. The power entering the electrical cabinet of the cold storage construction unit needs a three-phase five-wire system and must be reliably grounded. []
