Embodiment 1

[0032] This embodiment discloses as figure 1 A uniform temperature refrigeration and fresh-keeping transportation device with comprehensive heat exchange shown includes a ceiling radiation heat exchange terminal 1, an enhanced convective heat exchange terminal 2, a refrigeration host system 3 and a compartment 4.

[0033] In this embodiment, the ceiling radiant heat exchange terminal 1 includes a coil 101 for supplying cooling to the radiant panel, and a radiant ceiling 102 for radiative heat exchange with the compartment space.

[0034] The coil 101 in this embodiment is a common heat exchange copper tube, which is a bare tube without fins, and the heat exchange coil is a conventional technology.

[0035] In this embodiment, the radiant heat exchange ceiling 102 is an aluminum plate ceiling, which is connected with the coil pipe 101 to form a cooling end combination. The cooling end combination adjusts its working mode through the valve 302 and the valve 302. According to th...

Embodiment 2

[0043] In terms of specific implementation, this embodiment applies the uniform temperature refrigerated and fresh-keeping transportation device with comprehensive heat exchange to specific transportation scenarios.

[0044] During actual transportation, firstly, when the cooling terminal system in the compartment is first started, the enhanced convection heat exchange terminal 2 is used by default, the second valve 303 corresponding to the terminal 2 is opened, and the mixed flow fan 207 for air mixing in the compartment is opened, and at the same time Turn on the temperature acquisition system of the compartment, and compare the temperatures of 4 different measuring points in real time.

[0045] At this time, the entire airflow in the compartment is organized in the form of upward air supply and downward return. This air supply form can ensure the uniform mixing of the air in the compartment to the greatest extent and realize rapid cooling.

[0046] With the continuous opera...

Abstract

The invention relates to the field of refrigeration cold chain transportation, and discloses a comprehensive heat exchange uniform-temperature refrigeration fresh-keeping transportation device which comprises a carriage, a set of refrigeration main machine system, an enhanced convection heat exchange tail end and a ceiling radiation heat exchange tail end. The refrigeration main machine system comprises a conventional compressor, a condenser and an expansion valve. The enhanced convection heat exchange tail end comprises an air supply fan, a fan for mixing air in the compartment and two evaporators which are arranged in series front and back. The ceiling radiation heat exchange tail end comprises a heat exchange coil and a cold radiation ceiling. The two tail ends are connected with the refrigeration main machine system through respective valves and are used for switching working states. By means of different working characteristics of the two heat exchange tail ends, the problems that an existing cold storage cold chain transportation device is slow in pre-cooling, goods placement is limited, and temperature distribution in a compartment is uneven are solved, and the cold storage cold chain transportation device is suitable for the application fields of various cold storage cold chain transportation devices and the like.

Description

technical field [0001] The invention relates to the technical field of cold chain fresh-keeping transportation, in particular to a uniform-temperature refrigeration and fresh-keeping transportation device with integrated heat exchange. Background technique [0002] The fresh-keeping transportation device of fruits and vegetables is the most important part of the cold chain logistics of fruits and vegetables. In order to meet people's requirements for the quality of fruits and vegetables and ensure the freshness of fruits and vegetables, the cold chain transportation device must be able to achieve refrigeration and heat preservation, and ensure that the temperature in the refrigerated compartment is uniform. Large temperature fluctuations occur. At present, the commonly used refrigeration measures for cold chain transport compartments are the conventional direct expansion type, and the end of the air supply is a single evaporator. This form of refrigeration often has problem...
