Problems solved by technology

However, its disadvantage is that it requires a complex refrigeration system to charge the cold plate with refrigerant, and the cooling time is long, usually 8-12 hours
Moreover, the heat exchange efficiency between the cold storage bar and the air is not high, and the area required for the cold storage bar is larger, which increases the cost

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0023] Such as figure 1 , 2 As shown, a cold storage type refrigerated transportation system includes an insulated box 1 with a parallelepiped structure, and a partition 2 is arranged inside the insulated box 1, and the partition 2 divides the inner space of the insulated box 1 into The larger refrigerating chamber A and the smaller cold storage chamber B, the cold storage chamber B is specifically located between the partition plate 2 and the end wall of the heat preservation box 1 . The cold storage chamber B is provided with a cold plate 3 , a circulating fan 4 and an external coil 13 . The upper end of the partition 2 is provided with two air outlet holes 14, and the lower end is provided with two air inlet holes 5. The above-mentioned circulation fan 4 is fixed on the top wall of the box, and the input end of the circulation fan 4 faces downwa...

Abstract

The invention discloses a cold accumulation type refrigerated transporting system and a refrigerating method. The cold accumulation type refrigerated transporting system comprises a cold plate, a refrigerating medium coil pipe is arranged inside the cold plate, the side end of the cold plate is provided with a refrigerating medium inlet and a refrigerating medium outlet, one end of the refrigerating medium coil pipe is connected with the refrigerating medium inlet, and the other end of the refrigerating medium coil pipe is connected with the refrigerating medium outlet; an external connected coil pipe is arranged outside the cold plate, one end of the external connected coil pipe and the refrigerating medium inlet of the cold plate are connected to a first three-way valve, the other end of the external connected coil pipe and the refrigerating medium outlet of the cold plate are connected to a second three-way valve, and a circulating pump is arranged between the second three-way valve and the external connected coil pipe. Due to the fact that the side end of the cold plate is provided with the refrigerating medium inlet and the refrigerating medium outlet, and the refrigerating medium coil pipe is arranged inside the cold plate, heat exchanging can be carried out better in the process of refrigerating agent injecting. The refrigerating medium circulates inside the cold plate through the inlet and the outlet in the process of refrigerating agent injecting, and the temperature of a cold accumulation agent in the cold plate is reduced. Three-way valve positions are changed into a chilling mode after refrigerating agent injecting is finished, and the refrigerating medium is driven by the circulating pump to circulate through the external connected coil pipe.

Description

technical field [0001] The patent of the present invention relates to a refrigerated transport system, in particular to a cold-storage refrigerated transport system and a refrigerated method applied to refrigerated transport vehicles, refrigerated railway wagons and refrigerated containers. Background technique [0002] At present, cold storage refrigerated transportation is a refrigerated transportation technology with obvious advantages. It can not only fully guarantee the continuity and temperature stability of refrigerated transportation, but also ensure the transportation quality of frozen and refrigerated goods. It has the advantages of energy saving, environmental protection and low operating cost. The existing cold storage type refrigerated transport equipment mainly relies on sealed cold storage plates or cold storage strips to cool down to maintain low temperature. However, its disadvantage is that it requires a complex refrigeration system to charge the cold plat...
