Refrigeration device and vehicle with the same

Abstract

A refrigeration device is provided to solve a problem that present refrigeration device occupy space and consume extra energy. The device includes a liquefied gas supply module having a liquefied gasstorage tank; a control module having a solenoid valve communicating with the liquefied gas storage tank and a control unit electrically connected to the solenoid valve; a refrigeration module disposed in a refrigeration and having a vaporizing chamber communicating with the solenoid valve; and a gas discharging module having a venting valve communicating with the vaporizing chamber. The venting valve is electrically connected to the control unit and allows the liquefied gas to become the gaseous state from liquid state and absorb a large amount of heat energy in order to supply the required heat of vaporization of phase transition process, and then the abrupt temperature drop of vaporizing chamber can be used for freezing the refrigeration space. The invention further discloses a vehiclewith the refrigeration device.

Description

technical field [0001] The present invention relates to a refrigerating device and a vehicle with the refrigerating device, in particular to a refrigerating device and a vehicle which can control the phase transition of high-pressure liquefied gas and absorb heat energy to produce a cooling effect. Background technique [0002] Materials that must be stored at low temperature, such as: fresh food, frozen products, biological samples and industrial raw materials, etc., can be placed in a heat-insulated space, and a refrigeration device can be used to extract heat from the heat-insulated space, and the heat-insulated space can be isolated from the outside world Heat energy enters, and a low temperature environment can be maintained for material storage. The heat insulation space can be set in a factory building or a vehicle. [0003] Existing refrigerating devices need to be equipped with a compressor, which repeatedly compresses the refrigerant in a circulation pipe, so that ...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned existing refrigerating device, the configuration of the compressor will take up space and increase the overall weight, resulting in limited storage space and unfavorable transportation; in addition, the compressor needs to be driven by a power source or the engine of the vehicle to generate exhaust gas and noise affect the environment and cause additional energy consumption. In addition, when the power is cut off and the power is lost or the engine cannot be started, the low temperature environment cannot be maintained, and there is a risk of losing the cooling effect

[0005] Another existing refrigeration device uses pre-pressurized liquefied gas, which does not require an additional power source to drive during the refrigeration process, but the cooling rate and target temperature are not easy to control, and the liquefied gas is an inert pure substance, such as nitrogen , carbon dioxide, etc. If used in a confined space, the gas will gradually increase and the partial pressure of oxygen will decrease, which may lead to hypoxia and suffocation
