Description
Technical Field
The utility model relates to a van-type refrigerator car especially relates to a van-type refrigerator car refrigerating system.
Background
The van-type refrigerator car is a closed van-type transport vehicle for transporting frozen or fresh-keeping goods, is a special transport vehicle provided with a refrigerating unit, is commonly used for transporting goods such as biological agents, chemicals, frozen foods, dairy products, vegetables, fruits and the like, and ensures the requirements of the goods on the temperature environment in the transportation process. With the development of science and technology, higher requirements are also put forward on the performance of the refrigerating and fresh-keeping unit.
Since the goods are stored in the refrigerator carriage for a certain time, the carbon dioxide, the ethylene and other gas substances are easy to accumulate, and if the gas is not timely discharged from the carriage, the refrigeration or fresh-keeping effect of the goods can be influenced.
Disclosure of Invention
An object of the utility model is to provide a can in time discharge railway carriage or compartment formula refrigerator car refrigerating system of gaseous such as carbon dioxide, ethylene of railway carriage or compartment internal accumulation.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the refrigeration system of the van-type refrigerator car comprises a van body and a refrigerating unit;
a carbon dioxide concentration sensor for detecting the concentration of carbon dioxide in the compartment body is arranged in the compartment body;
the compartment body is provided with a ventilation part controlled by an electromagnetic valve, and the ventilation part is used for exchanging air inside and outside the compartment body;
and a data signal of the carbon dioxide concentration sensor is output to a cold machine controller of the refrigerating unit, and a control output end of the cold machine controller is electrically connected with a control input end of the electromagnetic valve and used for controlling the opening and closing of the electromagnetic valve.
The air exchange part comprises an air inlet pipeline and an air outlet pipeline which are arranged in the carriage body; the inner ends of the air inlet pipeline and the air outlet pipeline are respectively arranged in the compartment body, and the outer ends of the air inlet pipeline and the air outlet pipeline are respectively arranged outside the compartment body; the air inlet pipeline and the air outlet pipeline are communicated with the electromagnetic valve.
The utility model has the advantages of simple structure, good refrigerating and fresh-keeping effect of goods. The air in the carriage body can be timely replaced, gases such as carbon dioxide and the like are discharged, and fresh air is replaced, so that the goods can achieve a better storage and preservation effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic block circuit diagram of the present invention.
Detailed Description
As shown in fig. 1 and 2, the refrigeration system of the van-type refrigerator car of the present invention includes a van body 1 and a refrigeration unit 2;
a carbon dioxide concentration sensor 3 for detecting the concentration of carbon dioxide in the compartment body 1 is arranged in the compartment body 1;
the compartment body 1 is provided with a ventilation part controlled by an electromagnetic valve 4, and the ventilation part is used for exchanging air inside and outside the compartment body 1;
the data signal of the carbon dioxide concentration sensor 3 is output to a refrigerator controller of the refrigerating unit 2, and the control output end of the refrigerator controller is electrically connected with the control input end of the electromagnetic valve 4 and used for controlling the opening and closing of the electromagnetic valve 4;
the ventilation part comprises an air inlet pipeline 5 and an air outlet pipeline 6 which are arranged in the compartment body 1; the inner ends of the air inlet pipeline 5 and the air outlet pipeline 6 are respectively arranged in the compartment body 1, and the outer ends of the air inlet pipeline 5 and the air outlet pipeline 6 are respectively arranged outside the compartment body 1; the air inlet pipeline 5 and the air outlet pipeline 6 are communicated with the electromagnetic valve 4.
The working process is as follows:
in the process of transporting goods requiring refrigeration and freshness preservation, after a refrigerating unit 2 runs for a certain time, the concentration of carbon dioxide in a closed compartment 1 is higher and higher, at the moment, a carbon dioxide concentration sensor 3 arranged in the compartment 1 transmits a signal to a cold machine controller after detecting that the concentration of the carbon dioxide reaches a certain set concentration value, the cold machine controller transmits a control command to an electromagnetic valve 4 after receiving the signal, so that the electromagnetic valve 4 is opened, external fresh air enters the compartment 1 through an air inlet channel 5, meanwhile, the carbon dioxide in the compartment 1 is discharged out of the compartment 1 through an air outlet pipeline 6 until the concentration of the carbon dioxide in the compartment 1 is reduced to a certain concentration value, the carbon dioxide concentration sensor 3 transmits a signal to the cold machine controller again, the cold machine controller transmits a command to the electromagnetic valve 4 after receiving the signal, the electromagnetic valve 4 is closed, this completes the gas exchange in the car 1.
