LNG cold energy recycling air conditioner cooling device

Abstract

The invention discloses an LNG cold energy recycling and storage ice-making device, and particularly discloses an LNG cold energy recycling air conditioner cooling device. The LNG cold energy recycling air conditioner cooling device comprises an LNG vaporization heat exchange system and an air conditioner cooling heat exchange system, wherein the LNG vaporization heat exchange system comprises anLNG storage tank, an ejector, an energy accumulator, a superheater and a natural gas engine which are connected through an LNG pipeline, and the air conditioner cooling heat exchange system comprisesan energy accumulator, an air conditioner evaporator and a secondary refrigerant circulating pump which are connected through a secondary refrigerant pipeline. According to the LNG cold energy recycling air conditioner cooling device, cold energy is recycled by utilizing a vaporization process of LNG, and is used for cooling air conditioners and vehicle electronic heating elements of passenger compartments of an armored car and a tank vehicle, the structure is simple, electronic heating elements are few, the occupied space of the whole machine is small, various problems that the air conditioner cannot be installed on an existing armored car and tank vehicle can be solved, the air conditioner cooling performance of the armored car and tank vehicle is greatly improved, meanwhile, the invisibility of the vehicle is enhanced, and the operational performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of recovery and utilization of LNG cold energy, in particular to an air conditioner cooling device for recovery of LNG cold energy. Background technique [0002] Armored and tank vehicles are the main combat equipment of modern ground warfare. Generally, the cab space of these vehicles is small, and the engine and its electronic equipment inside the vehicle will release a lot of heat. Due to the structural design requirements of armor, tank vehicles, and combat stealth requirements, it cannot provide space for installing traditional air-conditioning systems. However, the temperature of the passenger compartment is suitable and the cooling of electronic components is good, which can better play the combat effectiveness of armored and tank vehicles on the battlefield. Therefore, it is particularly important for modern ground warfare to provide a small, simple, safe and stable armor, tank vehicle air-conditioning and co...

AI Technical Summary

Problems solved by technology

[0003] The existing air-conditioning and cooling devices for armored and tank vehicles have the following problems: 1. The system of the air-conditioning and cooling device is complicated and the volume is too large to provide enough installation space; 2. There are many electronic components, which are easily detected by infrared and have poor stealth performance; 3. Construction cost High, complex installation and difficult maintenance; 4. Due to the limitation of empty installation space, it cannot be installed in batches, and it is difficult to promote
