Valve 7 is connected with shut-off valve 9 before an expander；
The refrigerant inlet of the compressor 1 respectively with shut-off valve after shut-off valve 8 after an evaporator and an expander
10 are connected；
Evaporator 5 is provided between shut-off valve 8 after shut-off valve 7 and evaporator before the evaporator；
Expander 6 is provided between shut-off valve 10 after shut-off valve 9 and expander before the expander.
In the present invention, in specific implementation, it is provided with multiple air outlets 12 on the evaporator 5 and (is not limited to shown in FIG. 1
Two), the multiple air outlet 12 is by hollow air-exhausting duct to needing the interior space predeterminated position of refrigeration cool-down (such as secondary
The top of driving and other vehicle seats) outlet air.
In the present invention, in specific implementation, the surface of the evaporator 5 is provided at least one fan 11 and (is not limited to
One shown in FIG. 1), the fan 11 is connected with external power supply (such as Vehicular accumulator cell), empty where the fan 11
Between be connected with interior space (can be located at interior space in), the cold air formed for blowing evaporator 5 in evaporation makes
Obtaining cold air, quickly space cycle flows in the car, realizes good, fast cooling effect.
Shown in Figure 2, for the present invention, the expander 6 includes (i.e. one connection one together that is successively interconnected
It is a) multiple sub- expanders 60, the sub- expander 60 be hollow structure；
In specific implementation, the sub- expander 60 is preferably shaped to L shape, it is, of course, also possible to be other shapes.
In specific implementation, the sub- expander 60 preferably processes the expansion structure formed by hollow interior seat, when
So, other forms be can also be.
In specific implementation, every sub- expander 60 includes refrigerant inlet pipe 13 and refrigerant outlet pipe 14.
In specific implementation, for the sub- expander 60 that any two are interconnected, the refrigeration of one of them sub- expander 60
Agent outlet pipe 14 is connected by hollow corrugated connecting tube 15 with the refrigerant inlet pipe 13 of another sub- expander 60.
It should be noted that diversified forms can be used in the expander 6, inside is hollow form, and material cannot and be made
Cryogen reacts and density is small as far as possible.
It should be noted that between the interconnected component of any two being connected by one section of pipeline for the present invention
It is logical.
In the present invention, in specific implementation, the evaporator 5 be located in interior space or 5 place space of evaporator with
Interior space is connected, to be conducive to the evaporation by refrigerant, absorbs the heat of air in interior space.
In the present invention, in specific implementation, the condenser 2 is not located in interior space, is connected with the vehicle external space,
Convenient for car body external cooling.
In the present invention, it should be noted that the effect of expander 6 is that expansion required for providing refrigerant vapor is empty
Between, refrigerant can absorb heat in gasification, so that expander 6 can use example by interior heat storage in refrigerant gas
The refrigerant reaction used of such as aluminium and associated alloys discord and the small material of density are made.When expander is selected, should utilize as far as possible
Interior existing space, such as seat design can be used as expander 6 at hollow form, and multiple expanders may be implemented and be connected.
In order to which technical solution of the present invention is more clearly understood, specific work process of the invention is described in detail below.Its
Including two kinds of operating modes such as normal refrigeration work mode and insolation proof heating operating mode.
One, normal refrigeration work mode.Firstly, shut-off valve 10 after shut-off valve 9 before expander and expander is closed, and
Shut-off valve 8 after shut-off valve 7 before evaporator and evaporator is opened, compressor 1 sucks the refrigerant of low-temp low-pressure out of evaporator 5
After (such as ammonia), compressed action is carried out, the gaseous refrigerant for exporting high temperature and pressure enters in condenser 2, after condensing heat release,
The refrigerant for becoming liquid flows into liquid storage device 3 again, and then, the expanded valve 4 of the refrigerant of liquid enters in evaporator 5 after throttling,
Heat absorption is evaporated to gas (will be again introduced into compressor after evaporation) in evaporator 5, to realize and external circulation air
Heat exchange is carried out, guarantees that interior space maintains the environment of low temperature.
Two, insolation proof heating operating mode.After vehicle stops travelling, firstly, by shut-off valve 7 and evaporator before evaporator
Shut-off valve 8 is closed afterwards, if vehicle interior temperature is increased to preset value, shut-off valve 9 before expander is opened, the system in liquid storage device 3
Cryogen will enter in expander 6, refrigerant constantly evaporates in expander 6, to absorb car after the throttling of expansion valve 4
Heat, so that vehicle interior temperature be avoided to increase.Instantly when secondary vehicle launch, shut-off valve 9 before expander is closed, after opening expander
Shut-off valve 10, the refrigerant in expander 6 is inhaled into compressor 1, and pressure in expander 6 is constantly declined, when under pressure
After dropping to setting value, shut-off valve 10 after expander is turned off, opens simultaneously before evaporator shut-off valve 8 after shut-off valve 7 and evaporator,
Entire refrigeration system is normally freezed.
Therefore, above technical scheme is based on it is found that under vehicle inoperative driving status, if by Sunlight Action, it is internal
High temperature increases, and causes various disadvantages, for the refrigeration system for vehicle of anti-exposure heating provided by the invention, is meeting just
Often while refrigeration, moreover it is possible to realize that the cooling capacity under non-operating state provides, so as to avoid vehicle interior temperature in certain time
Acutely increase.
In conclusion compared with prior art, a kind of refrigeration system for vehicle of anti-exposure heating provided by the invention,
The rate of climb of vehicle interior temperature can be effectively reduced, improve the comfort level that people ride, solve car temperature of the vehicle under insolation
High problem is spent, is conducive to promote and apply, be of great practical significance.
In addition, for the present invention, can further avoid due to vehicle interior temperature it is excessively high caused by interior article burning
Or the generation of the precarious positions such as explosion.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
