How to choose the right refrigeration unit for refrigerated trucks

The refrigeration units of the refrigerated truck are divided into independent and non-independent refrigerators

Generally speaking, independent refrigeration units are one-piece structures, but there are also modified split structures (this structure is generally hoisted on the girder of the car), which itself has an engine and generator unit that provides power and electrical energy to the refrigeration system. Able to work independently, not limited by the working state of the car engine.

Non-independent refrigeration unit: It is a refrigeration unit that cannot work independently for refrigeration, and this kind of unit itself has no power unit and must rely on the automobile engine to drive the compressor to work.

Refrigerated car body material:The middle of the envelope 8cm insulation board filling, thickened FRP, high-strength adhesive, hot press forming, the outer frame is made of 304 stainless steel, thickened aluminum profile edging, 27 stainless steel door locks, accessories, door with beveled edges, auxiliary beams are made of 510 girder steel one-time folding, locked with a pressure plate, side protection net and rear bumper one-time molding.

The goods must be stacked on double-sided pallets; The plastic film should not be wrapped on the fresh-keeping pallet, as the film will block the circulation of cold air to the goods; Do not block the floor under the cargo.

The general refrigerated truck floor is made of aluminum guide rail floor with ventilation; However, there are also some refrigerated trucks that do not have aluminum rails and use flat non-slip floors. Usually used as a third-party transport company or for dairy products, the transport vehicle is made of a flat, non-slip floor, which is suitable for the transport of a wide range of products, or for easy cleaning of the floor. However, it must be noted that double-sided pallets must be used to load the goods to ensure the circulation of cold air on the ground.

It is strictly forbidden to stack goods directly on a flat floor.

1. Refrigerated truck refrigeration units are classified according to the place of production: they can be divided into imported refrigeration units and domestic refrigeration units. Imported refrigerators generally include the United States Da Leng Wang, the United States Carrier, South Korea Huasu and so on.

Domestic refrigeration units are generally commonly used by Guangdong K brand, Yingda Green Cold, Beijing Ice Source, etc.

2. Refrigerated truck refrigeration units are classified according to power: they can be divided into independent chillers and non-independent chillers. Stand-alone chillers have their own independent power**, while non-stand-alone chillers use the power of the vehicle to start refrigeration; That is to say, the free-standing chiller can still work when the vehicle is turned off to ensure the low temperature in the envelope.

Non-stand-alone refrigerators will not work, and when the vehicle is turned off, the refrigerator will also stop working, causing the temperature in the compartment to rise, resulting in the deterioration of the goods in the compartment. The choice of independent refrigerator or non-independent refrigerator first depends on the size of the selected chassis, the independent refrigerator is large in size, requires a certain installation space, and is suitable for installation on large refrigerated trucks; The non-freestanding chiller is small in size and is installed outside the cabin, close to the cab and does not take up space. In addition, the distance of the transportation route to choose the refrigerator, the general short-distance transportation to choose the non-independent refrigerator, long-distance transportation to choose the independent refrigerator.

Refrigeration units are divided into non-independent refrigeration units and independent refrigeration units. Domestic units and imported units, etc. Generally, external refrigerators are used, and a few miniature refrigerated trucks use built-in refrigerators.

For refrigerated trucks with low temperature requirements, a built-in cold plate can be adopted (the function is equivalent to that of an evaporator). At present, the refrigeration brands used in domestic refrigerated trucks mainly include: Leng Wang, Carrier, domestic K brand, Asiana, Shanghai Songhan, Xiangfan Hanxue, Denso, etc.

The refrigerated truck is usually 0 -5 at room temperature.

Look at what items are stored and transported, such as: the general seafood requirements are qualified for storage and transportation below -18 degrees after quick freezing, and if it is fresh vegetables and fruits, it should be in the range of less than 4 degrees and more than 0 degrees, and the requirements are different. However, as a refrigerated truck, it needs to have a wide adjustment range to store and transport different items.

It can be adjusted between -30 and 10 degrees to adapt to different food storage and transportation requirements.

Only the correct use and operation of refrigerated trucks can ensure the intact delivery and preservation of goods;

Because refrigerated trucks are specially used for temperature-sensitive products, temperature assurance is the key to refrigerated trucks. If it is not used or handled properly, it will result in the goods not being stored or shipped in good condition.

Like domestic products, there are Xiangfan Hanxue, Zhengzhou Kaixue, Xinxiang Huatai, Guangdong Jinda K brand, and if it is imported, it is the United States Carrier, the United States Cold King.

Here are the top 10 brands for your reference.

The refrigerated truck with an envelope body of more than 6 meters chooses more independent units, according to the different vehicles, such as trucks, trailers choose independent refrigeration units are also different, and trucks use medium-sized independent refrigeration units; Semi-trailers mostly use large refrigeration units, which are common refrigeration units arranged in front of the trailer.

Above are the top ten brands of refrigerated trucks, and below are the brands of refrigerated machines.

Domestic ones include Shangqiu Kaida, Zhengzhou Kaixue, Xinxiang Huatai and so on. The main imports are Carrier and Leng Wang.

The refrigerated truck units used by our Chengli manufacturers include Hanxue, Songhan, Kelly, Kaili, Jinda, **There is a difference, you can consult me, what kind of box is used and what unit is particular.

And-15 which refers to both specifications.

The first step in choosing a refrigerated truck refrigeration unit is to determine whether you are using a refrigerated truck for long-distance transportation or short-distance transportation in the city.

1) For long-distance transportation, it is recommended that you buy a car of more than 7 meters and use an independent refrigeration unit (integrating engine, generator and compressor in one).

2) Short-distance city distribution, buy a 3-6 meter car, low cost and easy to operate, with a split non-independent refrigeration unit (engine driven compressor refrigeration) can be, of course, if you feel necessary or the budget is enough, it is better to buy a separate unit.

Second, the selection of the refrigerator is related to the size of the volume of the refrigerated compartment you purchased, in addition to the fresh-keeping type and low-temperature freezing type of the refrigerator.

Generally, fruits, vegetables, vaccines, etc. are transported with a fresh-keeping refrigerator (the temperature of the compartment can generally be kept at about 5 degrees).

In addition, ice cream, frozen products, etc., require low-temperature freezing units (the temperature is below -15 degrees).

A few common refrigerated models are as follows:
