Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing:

[0026] Such as figure 1 As shown, the air conditioning system is a hybrid air conditioning system, including two cycles and three working modes. The two cycles of the system include: 1) The ejector refrigeration cycle using the waste heat of the vehicle as the energy source, the circuit is (g)-(d)-(b)-(c)-(f)-(g), including the pump , generator, ejector and condenser and other components; 2) Compressor refrigeration cycle (e)-(a)-(b)-(c)-(f)-(e), this cycle includes electronic expansion valve (EEV ), evaporator, compressor, ejector and condenser. In the ejector cycle, the waste heat generated during the operation of the vehicle is collected and recovered by the generator and absorbed by the refrigerant in the generator. After the refrigerant absorbs heat, it becomes high-pressure steam, which is used as the primary flow of the ejector. In the compressor refrigeration cycle...

Abstract

The invention discloses a multi-mode waste heat driven automobile air conditioning system which comprises an ejector refrigerating cycle loop and a compressor refrigeration cycle loop. The ejector refrigeration cycle loop is formed by sequentially connecting a pump, a generator, an ejector and a condenser. The compressor refrigeration cycle loop is formed by sequentially connecting an electronic expansion valve, an evaporator, a compressor, an ejector and a condenser. The multi-mode waste heat driven automobile air conditioning system provides a novel automobile air conditioning ejection type refrigerating cycle and used for improving an existing commonly-used air conditioning compression refrigeration cycle. A compression refrigeration mode and an ejection refrigeration mode are combined, waste heat produced in the running process of an automobile is effectively utilized, and meanwhile the problem that the energy utilization rate is low, condenser-side pressure is not easy to control and the like in a traditional ejector type refrigeration mode is solved. The compressor power consumption in a tradition system is remarkably reduced by utilizing the ejectors, and the system stability is improved.

Description

technical field [0001] The invention relates to the technical field of waste heat-driven automobile air-conditioning systems, in particular to a multi-mode waste-heat-driven automobile air-conditioning system. Background technique [0002] With the rapid development of the domestic economy, my country's energy problems have become increasingly acute, and energy has become an important factor restricting China's long-term sustainable development. At the same time, with the corresponding increase in residents' income, the number of automobiles in my country is also increasing rapidly year by year, and the proportion of automobile energy consumption in the total energy consumption is also increasing. As a typical heavy industry, the automobile industry began to flourish at the beginning of the last century and has always been an important source of energy consumption. At present, most of the models on the market use gasoline and diesel as driving energy, and only a few of them...
