The utility model is characterized in that: the device also has a generator and an absorber; the condenser is positioned inside the generator and the evaporator is positioned inside the absorber. The utility model has a plurality of heat exchangers, with one heat exchanger positioned on the engine exhaust pipe, another heat exchanger positioned in the cooling water pipeline passing the condenser and a third heat exchanger positioned between the generator and the absorber. The refrigerator is provided in the cooling water pipelines of the evaporator and the condenser, and an electric heater is installed in the pipeline before the generator. Aimed to fully make use of engine waste heat, the utility model technically applies a generator and an absorber to realize vehicle air-conditioning at zero cost.

Description

Air conditioner for motor vehicle

Technical field

The utility model belongs to a kind of aircondition, especially relates to a kind of air conditioner for motor vehicle.

Background technology

Existing car air-conditioner structure generally is made of critical pieces such as compressor, condenser and evaporimeters, and critical piece connects into refrigerating plant through accessories such as pipeline, valve bodies.During work, compressor is compressed into HTHP with refrigerating fluid, finishes a kind of cold and hot transfer process through condenser and evaporimeter again and reaches refrigeration or heat purpose.The problem of its existence is: therefore the required kinetic energy of compressor, increased the work oil consumption of engine from engine in the refrigerating plant.

Summary of the invention

For overcoming the above-mentioned deficiency of prior art, the utility model aims to provide a kind of air conditioner for motor vehicle with novel structure, and this device can reach refrigeration equally or heat purpose under the situation that does not increase the engine operation oil consumption.

The technical scheme that adopts is as follows for achieving the above object, the structure of this air conditioner for motor vehicle comprises condenser, evaporimeter, refrigerator and heat exchanger, heat exchanger, condenser and evaporimeter are connected by pipeline, it is characterized in that: this device also has a generator and an absorber, condenser is arranged in the generator, and evaporimeter is arranged in the absorber; Heat exchanger has many, and wherein a heat exchanger is arranged on the exhaust pipe of engine, and a heat exchanger is arranged on through in the cooling water pipeline of condenser, and a heat exchanger is arranged between generator and the absorber; Refrigerator is arranged in the cooling water pipeline of evaporimeter and condenser.

Be provided with an electric heater in the pipeline before entering generator.

Beneficial effect: the utility model by setting up the technological means of generator and absorber, has realized using the purpose of car air-conditioner zero cost from making full use of engine exhaust heat.

Description of drawings

Fig. 1 is the fundamental diagram of an embodiment.

The specific embodiment

Referring to Fig. 1, sequence number is represented respectively among the figure: generator 1, condenser 2, evaporimeter 3, absorber 4, engine 5,

heat exchanger

6,6a, 6b,

reversal valve

7,7a, 7b, 7c, water tank 8, pressure-reducing valve 9, solution pump 10, choke valve 11, vacuum valve 12, electric heater 13, refrigerator 14, blast pipe 15.

The structure of this air conditioner for motor vehicle comprises condenser 2, evaporimeter 3, refrigerator 14 and

heat exchanger

6,6a, 6b, and

heat exchanger

6,6a, 6b, condenser 2 and evaporimeter 3 are connected by corresponding pipeline.For utilizing the waste heat of engine 5 and blast pipe 15, this aircondition has been set up a generator 1 and an absorber 4, and condenser 2 is arranged in the generator 1, and evaporimeter 3 is arranged in the absorber 4; Heat exchanger has many, and wherein a heat exchanger 6b is arranged on the blast pipe of engine 5, and a heat exchanger 6 is arranged on through in the cooling water pipeline of condenser, and a heat exchanger 6a is arranged between generator 1 and the absorber 4; Refrigerator 14 is arranged in the cooling water pipeline of evaporimeter 3 and condenser 2.Because parts such as generator 1, absorber 4 are standard structure member in the existing air-conditioning technical, just profile varies in size and different, and for this reason, the inventor repeats no more its structure.

The purpose of setting up electric heater 13 in the pipeline before entering generator 1 is: the refrigeration when increasing engine 5 startup just.

Operation principle:

During refrigeration: the temperature behind the cooling line of engine 5 and heat exchanger 6b in the blast pipe 15 and electric heater 13 of the superconductive medium in the pipeline gets a promotion, after entering generator 1 the moisture content vaporization in the cold-producing medium (cold-producing medium employing bromize lithium dilute solution of the present utility model) is evaporated, solution then is concentrated, concentrated solution is by gravity and action of pressure, flow to heat exchanger 6a, flow in the absorber 4 after pressure-reducing valve 9 decompressions, absorbing steam becomes weak solution; Steam in the generator 1 then enters in the condenser 2, and condenses into water as refrigerant, and cooling water was taken away in liberated heat was cooled and manages during condensation, and water as refrigerant is inflow evaporator 3 after choke valve 11 throttlings, once more by the heat absorption evaporation.Lower the temperature behind the cooling water loss of heat, cooling water pipe realizes that through refrigerator 14 cold scattering reduces the vehicle interior temperature purpose.The steam that evaporimeter 3 evaporates continues to flow in absorber 4, absorbed by the cold-producing medium of the inside, the cooling water that the heat that discharges in the absorption process is cooled in the water pipe is taken away, the rare cold-producing medium that comes out from absorber 4 is sent to generator 1 heating by solution pump 10 through heat exchanger 6a, and so process of refrigerastion is constantly finished in circulation.

When heating: by controlling the switch of each reversal valve 7, by drawing hot blast the heat exchanger 6 of air blast from noise elimination blast pipe 15 (certainly, also devices such as relevant gravity-flow ventilation, air cleaning, humidification, automatic control can be designed wherein simultaneously as required, to play corresponding effect).
