Embodiment

[0033] In the following, for the convenience of description, it is assumed that the first battery B1 is in a normal state and the switch SW is in a closed state. Specific switching control of the switch SW will be described later.

[0034] After the freezer switch 15d on the control panel 25 is turned on, the control device 23 can detect the temperature inside the freezer 31 by the temperature sensor 25. temperature, the number of revolutions of the compressor 13 is controlled. In other words, the control device 23 outputs a rotation speed instruction for controlling the compressor 13 to the non-circuit IV according to the detection value of the temperature sensor 27 and the setting value on the control panel 25, and the control unit 51 of the non-circuit IV controls the compressor 13 according to the rotation speed instruction. The switches of the switch components Q1~Q6 convert the rectification circuit D1 into direct current, the electricity output from the first generator...

Abstract

The invention belongs to the technical field of refrigeration and cold storage, and particularly discloses a refrigeration and cold storage device for vehicles. The refrigeration and cold storage device comprises an engine, a first power generator connected with the engine, a power conversion device connected with the first power generator, an AC commercial power input device connected with the power conversion device, a compressor connected with the power conversion device, a first heat exchanger, a refrigerator, a temperature sensor, a power conversion device, a control panel, an antenna, a remain meter, a first blower, a second blower and a second power generator, wherein the first heat exchanger and the refrigerator are connected with the compressor; a second heat exchanger is connected with the refrigerator; the temperature sensor, the power conversion device, the control panel and the antenna are connected with a control device respectively; the remain meter is connected with a first battery and a power transformer; the first blower, the second blower and the second power generator are connected with a second battery respectively; the second power generator is connected with a DC / DC converter. The refrigeration and cold storage device has the advantages that various power supply modes are provided, power is supplied to the compressor through the first power generator, a commercial power supply and the first battery to maintain the refrigeration or cold storage function, and the power supply state is stable.

Description

technical field [0001] The invention relates to the technical field of freezing and refrigeration, in particular to a refrigeration and refrigeration device for vehicles. Background technique [0002] In general, refrigerated vehicles exist as vehicles for transporting frozen food and fresh ingredients. A freezer truck is a freezer that can store food, etc., and has the function of freezing or refrigerating. It is equipped with a freezer to keep the freezer at a specified low temperature. [0003] Such as Figure 6 As shown, the car refrigeration device has a compressor 5 for compressing the refrigerant when the car engine E is started, a compressor 7 for compressing the refrigerant when the car engine E is stopped, a motor M for driving the compressor 7, and a heat exchanger 14 for condensing the refrigerant. 1. Evaporate the refrigerant condensed by the heat exchanger 15 to cool the heat exchanger 17 inside the freezer 31, send the air blowers 19 and 21 for heat exchange ...
