Technical field
The utility model relates to automotive air-conditioning system, especially a kind of air-conditioning system of utilizing engine waste heat.
Background technology
Current, automotive air-conditioning system is for adopting the mode of traditional mechanical commprssor compression to freeze, and mechanical commprssor is by motor driven.Mechanical commprssor can increase load and the oil consumption of engine, and neither energy-conserving and environment-protective also can produce noise and vibration, affect driver comfort.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of energy of usining engine waste heat as the automotive air-conditioning system of compression power, thus load and the oil consumption of engine reduced.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of air-conditioning system of utilizing engine waste heat, comprise compressor set, condenser and evaporimeter, described compressor set comprises mechanical commprssor and injection type compressor reducer, the output of described mechanical commprssor is connected with the refrigerant inlet of condenser, the refrigerant outlet of condenser is connected with expansion valve with the refrigerant inlet of heater respectively by flow control valve, described heater comprises refrigerant passage and heating agent path, refrigerant passage is connected with injection type compressor reducer with control valve, heating agent path is connected with cooling water pipe or the blast pipe of engine, described expansion valve is connected with the refrigerant inlet of evaporimeter, the refrigerant outlet of described heater is connected with two inputs of injection type compressor reducer respectively with the refrigerant outlet of evaporimeter, the output of injection type compressor reducer is connected with the input of mechanical commprssor.
Beneficial effect: the utility model air-conditioning system utilizes the energy of engine waste heat as compression power, energy consumption reduces greatly, not only greatly reduce load and the oil consumption of engine, the output of car load power is promoted, and improved engine radiating performance and driver comfort.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-heater, 2-flow control valve, 3-condenser, 4-mechanical commprssor, 5-injection type compressor reducer, 6-expansion valve, 7-evaporimeter, 8 refrigerant passage, 9, heating agent path.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is done further and explained.
As shown in Figure 1, the air-conditioning system of engine waste heat of utilizing of the present utility model comprises compressor set, condenser 3 and evaporimeter 7, compressor set comprises mechanical commprssor 4 and injection type compressor reducer 5, the output of mechanical commprssor 4 is connected with the refrigerant inlet of condenser 3, the refrigerant outlet of condenser 3 is connected with expansion valve 6 with the refrigerant inlet of heater 1 respectively by flow control valve 2, heater 1 is heat-exchangers of the plate type or tubing heat exchanger, heater 1 is provided with the heating agent path 9 being connected with cooling water pipe or the blast pipe of engine and the refrigerant passage 8 being connected with injection type compressor reducer 5 with control valve 2, expansion valve 6 is connected with the refrigerant inlet of evaporimeter 7, the refrigerant outlet of the refrigerant outlet of heater 1 and evaporimeter 7 is connected with two inputs of injection type compressor reducer 5 respectively, the output of injection type compressor reducer 5 is connected with the input of mechanical commprssor 4.
During air conditioner refrigerating, mechanical commprssor 4 compression refrigerant gas, make it become the gas of HTHP.Refrigerant gas after compression enters condenser 3 liquefaction, and a cold-producing medium part for liquefaction enters expansion valve 6 through flow control valve 2, enters afterwards evaporimeter 7 and is evaporated, and becomes low-temp low-pressure gas, freezes.
The cold-producing medium of another part liquefaction, in flow control valve 2 enters heater 1, is heated by the engine exhaust of high temperature or engine cooling water, and the cold-producing medium that becomes high temperature and high pressure gas after heating enters injection type compressor reducer 5.In injection type compressor reducer 5, high temperature and high pressure gas sprays at a high speed through jet pipe step-down, and the low-temp low-pressure gas that injection is come in from evaporimeter 7 after two kinds of gases mix, then underspeeds through diffuser pipe, increases pressure and enters mechanical commprssor 4.Like this, being compressed by injection type compressor reducer 5 from evaporimeter 7 low-temp low-pressure gas out, pressure raises, and the gas pressure that enters mechanical commprssor 4 increases, the pressure differential that mechanical commprssor 4 is imported and exported reduces, i.e. the energy consumption of mechanical commprssor 4 also decreases.The output of car load power promotes, fuel consumption reduction, and engine radiating performance and driver comfort are also improved.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
