[0020] The working principle of booster injector is as follows figure 1 shown. The booster injector 9 injects low-temperature and low-pressure liquid with high-temperature and high-pressure motive steam. After mixing, the steam is condensed, and its condensation heat is converted into pressure potential energy. The mixed liquid with a pressure higher than that of the steam inlet can be obtained at the outlet of the injector. Depend on figure 1 The pressure distribution at each position of the middle injector shows that the outlet pressure of the booster injector is higher than the inlet pressure, and the difference in vapor pressure between the inlet and outlet is related to the status of the booster injector and the working fluid. When the pressurized injector is applied to the absorption refrigeration cycle, the high-temperature and high-pressure refrigerant vapor at the outlet of the generator is used as the motive steam to inject the low-temperature and low-pressure dilut...

The invention discloses a tail gas drive absorption type automobile air conditioner without a mechanical pump and relates to the field of automobile accessories. Compared with a conventional absorption type refrigerating cycle, the maximum innovation of the cycle of the tail gas drive absorption type automobile air conditioner without the mechanical pump in a system is that a pressurization injector substitutes a solution pump, and the whole system is 100% driven by low-grade heat energy. The system is free of any motion component, operation is reliable and stable, the service life is long, the structure is simple, the occupied space overall is small, and the space arrangement requirement of the automobile air conditioner is met. By the adoption of the system, the structure of an absorberin the conventional absorption type refrigerating cycle is improved as well, a refrigerating agent and an absorption agent make full contact through the padding type heat insulation absorber, and a mixed solution can reach a saturation condition more easily. Through additional arrangement of a liquid-liquid injector, the gas absorption pressure is increased, absorption is enhanced, meanwhile, thegas consumption of the pressurization injector is reduced to the maximum degree, and therefore the operation efficiency of the system is improved.
Description
technical field [0001] The invention relates to the field of auto parts, in particular, the invention relates to an exhaust gas-driven absorption type automobile air conditioner without a mechanical pump. Background technique [0002] Most of the existing automotive air-conditioning systems are still conventional vapor compression refrigeration cycles. Compared with absorption refrigeration systems, its energy source is high-grade mechanical energy or electrical energy. Unutilized waste heat directly takes away a large amount of energy from fuel, which greatly reduces the energy utilization efficiency of the vehicle, which will inevitably lead to a decline in vehicle endurance, energy consumption ratio and economic benefits. [0003] At present, most absorption refrigeration cycles are lithium bromide-water refrigeration cycle, ammonia salt (ammonia water) refrigeration cycle and absorption-diffusion refrigeration cycle. Among them, the lithium bromide-water refrigeration c...
