Problems solved by technology

[0011] However, traditional automotive air-conditioning systems pass the refrigerant directly to the evaporator for evaporation and heat absorption, reducing the temperature in the cabin.
However, for CO 2 Automobile air conditioning system, when the refrigerant leaks, CO 2 will go directly into the cabin

Abstract

The invention discloses a safe and environment-friendly automobile air conditioning system. The safe and environment-friendly automobile air conditioning system is composed of a cooler, an expansion valve, an intermediate heat exchanger, a compressor, a secondary refrigerant pipeline, a cabin heat exchanger and a fan. An outlet of the compressor is connected with an air inlet of the intermediate heat exchanger through the cooler and the expansion valve. An air outlet of the intermediate heat exchanger is connected with an inlet of the compressor. A secondary refrigerant pipe in the intermediate heat exchanger is connected with a secondary refrigerant pipe of the cabin heat exchanger through the secondary refrigerant pipeline. The air conditioning system is filled with a working medium of CO2 or R1234yf, and the refrigerant pipeline is filled with a nano fluid secondary refrigerant. The safe and environment-friendly automobile air conditioning system can separate the refrigerant from acabin, and the nano fluid secondary refrigerant is only led into the heat exchanger in an automobile for heat exchanging with air of the cabin. During refrigerant leaking, a refrigerant is directly leaked into the environment and cannot cause damage to people in the automobile. Therefore, the system has the advantages of safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an automobile air conditioning system in which nanofluid is used as a brine. Background technique [0002] After more than 40 years of development, the technical level of my country's automotive air-conditioning products has been greatly improved, but its technical content is still lower than the international advanced level. For the vast majority of automotive air conditioners currently on the market, the refrigerant charged is R134a, and its global warming potential (GWP) is 1430, which belongs to the category of "high GWP" and is listed in the "Kyoto Protocol". One of the greenhouse gases that implement emission reductions. [0003] With the development of modern economy, governments of various countries attach great importance to the environment. The F-gas law passed in Europe in 2006 stipulates that new cars manufactured in 2017 must not use refrigerants with a GW...
