What should we pay attention to when designing cold chain logistics?

What should be paid attention to in the design of cold chain logistics? Cold chain logistics is an important way for us to transport food. The emergence of cold chain logistics has made our food no longer seasonal. What should be paid attention to in the design of cold chain logistics?

The design of cold chain logistics should pay attention to the following points:

1. The refrigeration cycle system adopts centralized refrigeration. A set of refrigeration units is connected to the low-temperature warehouse evaporator through a pipeline to cool the warehouse. The whole system consists of a compressor, an oil separator, a condenser, a liquid storage device, a dry filter, a sight glass, a solenoid valve, a stop valve, an expansion valve, an evaporator, a gas-liquid separator, etc.

2. Liquid supply method: The entire refrigeration system uses a liquid pump for liquid supply, which is uniform and has high heat exchange efficiency. Liquid pump liquid supply, that is, full liquid supply, uses the mechanical force of the liquid pump to transport low-temperature refrigerant liquid to the evaporator. The liquid supply system is mainly composed of a low-pressure circulation barrel, a fluorine pump, a liquid (gas) regulating station, a solenoid valve, an expansion valve, a liquid level controller, a pressure difference controller, a check valve and an automatic bypass valve, and is widely used in logistics cold storage design.

3. Logistics cold storage usually adopts screw parallel units with economizers, equipped with highly optimized body structure, efficient motors, durable bearings and better optimized oil circuits, oil separators and large-area oil filters; fully automatic and safe operation, always monitoring the unit operating parameters, with fault warning function to ensure safe and reliable operation of the unit; screw units have good economy, compact structure and reliable use.

4. Evaporative condensers are generally used in flow cold storage. Evaporative condensers are composed of water distribution system, condensing coil group, packing heat exchange layer, water collector, circulating pump, axial flow fan, maintenance channel, etc., integrating condenser, water pump and cooling tower. It is easy to install and use, occupies a small area, and has low comprehensive investment. It is especially suitable for arid and water-scarce areas.

5. The cold storage control system is a PLC and Jingchuang microcomputer control system, which can be automatically switched on and off conveniently and accurately. Adjust the operating parameters of the cold storage. System fault protection and alarm output. Heating and frost fusion. Automatic control, simple operation. Intelligent. Beautiful appearance, centralized control of compressor. Condenser. Cooler. Frost operation, etc., can maximize the utilization efficiency of the system.
