Embodiment Construction

[0014] like figure 2 As shown, the working principle of an air circulation system of a large vehicle according to an embodiment of the present invention is adopted. exist figure 2 In the system shown, the fresh air is first purified by the air filter 1 . The purified air passes through the second diverter three-way valve 21, a part of which directly enters the pipeline through the left and right passages, and the other part first enters the supercharger kit 2 driven by the crankshaft drive 23 connected to the engine shaft through the bypass; then the above-mentioned The two parts of air are mixed and enter the compressor 4; the compressor 4 increases the pressure by absorbing the expansion work of the exhaust gas turbine 5; the turbine 5 is driven by the exhaust gas of the engine 3. The air coming out from the compressor 4 is controlled by the first diverter three-way valve 22, a part of the air enters the intercooler 6 to cool, and then blows into the combustion chamber o...

Abstract

The invention discloses a refrigeration system related to an engine. Partial high pressure air is led out of a turbocharged engine to serve as a high pressure air source of an air refrigeration cycle system to drive an air-conditioning system to perform refrigeration cycle. The air refrigeration cycle system consists of a three-way valve connected to an air supply pipeline of the turbocharged engine, a centrifugal-flow compressor, a radial axial turbine and an air cooler. The compressor and the turbine work coaxially, and the three-way valve is used for regulating the flow rate of turbocharged high pressure air entering the air refrigeration system. By the method, the air supercharging function and the refrigeration function of the traditional air refrigerant can be realized simultaneously, and a bottleneck of the traditional air refrigeration cycle is overcome. The invention is simple and feasible, and convenient to install and operate, and can improve the energy utilization rate of the engine.

Description

technical field [0001] The utility model relates to an air refrigeration cycle system suitable for large vehicles. The system has the characteristics of light weight, easy control and adjustment, and is suitable for solving the problem of air temperature regulation in large vehicles such as high-speed trains and armored vehicles. Background technique [0002] The air refrigeration cycle system is a system that uses air as the refrigeration medium and provides refrigeration according to the principles of thermodynamics. A conventional air circulation system usually includes a source of pressurized air at a suitable pressure, a heat exchanger, and an air cooling system including a compressor and a turbine. The air pressure of the air source must be higher than the pressure of the outlet air of the turbine, so as to form a pressure difference and overcome the frictional resistance inside the pipeline flow path and the air refrigerator to drive the refrigerator to run. So how t...
