Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
As Figure 1-4, a kind of vehicle waste heat air-conditioning, including heat-exchanger rig 1, vaporising device 2, cooling device 3 and retaining
Device 4, the heat-exchanger rig 1 includes accumulator 101, the first stop valve 102 and check valve 103；The vaporising device 2 includes spray
Mouth 201, evaporation tube 202, the fan 204 of diffuser 203 and first；The cooling device 3 includes the fan of condenser 301 and second
302；The water-storing device 4 includes cistern 401, the second stop valve 402 and pump 403；The outlet and energy storage of the check valve 103
The lower end of device 101 is connected, and one end of first stop valve 102 is connected with the upper end of accumulator 101, the first stop valve
102 other end is connected with the entrance of nozzle 201, and the outlet of nozzle 201 is connected with one end of evaporation tube 202, evaporation tube
202 other end is connected with the entrance of diffuser 203, and the outlet of the diffuser 203 is connected with the entrance of condenser 301
Logical, the outlet of condenser 301 is connected with cistern 401, and one end of the second stop valve 402 is connected with the upper end of cistern 401
Logical, the other end of the second stop valve 402 is connected with evaporation tube 202, and the entrance of the pump 403 is connected with cistern 401, pump
403 outlet is connected with the entrance of check valve 103；First fan 204 is arranged in by evaporation tube 202, second wind
Fan 302 is arranged in by condenser 301；Water is filled in the accumulator 101；Water is filled in the cistern 401；The evaporation tube
Water is filled in 202.
Further, as shown in Figure 3 and Figure 4, the nozzle 201 and diffuser 203 are convergence-expansion pipe, that is,
Famous Laval nozzle.
The course of work of the present invention is as follows：
First the first stop valve 102 and the second stop valve 402 are opened, whole air-conditioning system is evacuated, as far as possible will
The inside air is drained only.Then two stop valves are shut, it is by the heat of automobile engine that the water in accumulator 101 is (actual
Upper is exactly the cooling water in engine) it is heated to close to 100 degree, at this moment the pressure of the inner vapor of accumulator 101 is close to 1bar, and
System other parts are still vacuum state.The first stop valve 102 is opened during operation of air conditioner, due to the pressure before and after nozzle 201
At this moment difference, water vapour will just can reach at a relatively high vacuum with supersonic flow delivery nozzle 201 in evaporation tube 202.At this moment again
The water in cistern 401 will be inhaled by the second stop valve 402 by opening the vacuum in the second stop valve 402, evaporation tube 202
Enter, a number of water is just had in evaporation tube 202.Due to being high vacuum in evaporation tube 202, the water of the inside is absorbed by environment
Evaporated by the heat that tube wall is transmitted so that the wall of evaporation tube 202 reaches very low temperature.Pass through heat exchange, the first wind
Fan 204 blows out the cold of evaporation tube 202, accelerated heat convection current, to reach the purpose of refrigeration.The supersonic speed that nozzle 201 flows out
Steam stream takes the steam of the inner water evaporation of same evaporation tube 202 together, still can reach supersonic speed.Mixed vapour stream passes through diffuser
After 203, speed reduction, less than velocity of sound, and pressure and temperature is raised simultaneously.Vapor after temperature rise passes through condenser 301
Shi Jinhang is cooled down, and water is condensed into by the second fan 302.Condensed water flows into cistern 401, at this moment the pressure in cistern 401
Power is higher than the pressure in evaporation tube 202.Because the water in accumulator 101 constantly evaporates, quantity will be reduced constantly.Work as accumulator
When water in 101 is reduced to a certain extent, pump 403 is opened, the water in cistern 401 is injected into accumulator 101.Cistern 401
In a water part flow into evaporation tube 202, it is most of all to inject accumulator 101.When not needing air-conditioning, just by the first stop valve
102 and second stop valve 402 close.So circulation, it is possible to reach the purpose for realizing refrigeration.
Above-described embodiment is used for illustrating the present invention, rather than limits the invention, the present invention spirit and
In scope of the claims, any modifications and changes made to the present invention both fall within protection scope of the present invention.
