Abstract

The invention discloses an automotive air conditioning system using the cold energy of liquefied natural gas, which comprises a liquefied natural gas system consisting of an LNG (Liquefied Natural Gas) storage tank, a low temperature valve, a low temperature pump and the like, an ethylene glycol solution system consisting of a third electric three-way regulating valve, an ethylene glycol storage unit, an air heat exchanger, an ethylene glycol solution pump and the like, a direct contact boiling heat transfer system consisting of an ethylene glycol spray tank, a first gas/liquid separator, a second gas/liquid separator, a natural gas storage tank and the like, an automobile engine cooling water system consisting of an electric valve, an automobile engine, a cooling water tank, a cooling water pump, an air cooled water cooler and the like, and connection components of the automobile engine cooling water system. In the automotive air conditioning system, ethylene glycol solution is used as cooling medium, the direct contact boiling heat transfer way in which the liquefied natural gas is sprayed upwards from the bottom and the ethylene glycol solution is jetted downwards from the top is adopted in the ethylene glycol spray tank, thus the cold energy of the ethylene glycol solution is utilized to cool the space of an automotive air conditioning room in summer and heat the space of the automotive air conditioning room in winter.

Description

technical field [0001] The invention relates to the technical field of green environment-friendly automobiles and efficient energy recovery and utilization, in particular to an automobile air-conditioning system utilizing the cooling capacity of liquefied natural gas. Background technique [0002] Automobile air conditioners have brought many negative effects while creating a comfortable environment for the cabin. At present, automobile air conditioners mostly use R134a vapor compression refrigeration system. The compressor is driven by the automobile engine through the coupling system. The vapor compression refrigeration system not only consumes the power of the automobile engine, but also easily causes refrigerant leakage. Liquefied Natural Gas (LNG for short), the main component is methane, as a clean and low-pollution alternative fuel for vehicles, it has high energy storage density, long continuous mileage for one charge, and low pressure and light weight of the vehicle...
