Description
Technical field
The utility model is related to a kind of air-conditioning system, more particularly to a kind of air-conditioning system for container.
Background technology
From the sixties in last century, container just has been developed as a kind of international means of transport of multistage through transport.
It using container transshipment goods, can directly be freighted in the warehouse of consignor, transport the warehouse unloading of consignee, midway is changed
Car, ship time, change the outfit without goods is taken out out of case.Container as international freight forwarding main carriers, because it possesses transport
Safe, operation is simple, and packaging material is saved, and the efficiency of loading and unloading is high, and cost of transportation is low, many advantages, such as being easy to automatic management,
And be widely used in a variety of combined transportation modes that air transport, shipping and land transportation are combined, it is considered as sea, land and sky transport
Important carrier.
Pressurised containers are mainly used in such as desert, offshore oil drilling platforms danger zone.It is multiple in these danger zones
Miscellaneous harsh use environment proposes very high requirement to the air-conditioning system used in container, for example：Can be extraneous 53 DEG C
Normally run under hot environment, and maintain 24 DEG C or so comfort temperatures in case；Can be under coastal high humility, high salt mist environment not
Corrosion；Meet the external requirement to explosion-proof area equipment；Meet the requirement of the industry standards such as ATEX, DNV；Can be in countries in the world
In the range of it is general；50/60Hz is general.
However, the domestic air-conditioning system for not complying fully with above-mentioned requirements still.Domestic common house container is generally adopted
With the air-conditioning system of household, i.e., common comfort air conditioning system.And this common comfort air conditioning system is typically only capable to adapt to 35 DEG C of highest
Left and right outdoor temperature environment, if beyond the temperature, just occurring that operating pressure is raised, condensation effect is poor, and refrigerating efficiency is serious
Decline is not freezed even, and refrigeration piping weld is easily revealed, compressor protection or failure, and service life reduction etc. is asked
Topic.It is therefore desirable for obtaining a kind of air-conditioning system for container, the air-conditioning system can meet in complicated harsh use environment
Requirement, filled the domestic gaps in the field.
Utility model content
One of the purpose of this utility model is a kind of air-conditioning system for container of offer, and the air-conditioning system can be applied
In container especially pressurised containers, and complicated harsh use environment is can be suitably used for, may be particularly applicable to such as desert, coastal waters
The danger zones such as oil drilling platform.
In order to achieve the above object, the utility model provides a kind of air-conditioning system for container, and it includes：Switching
Ground is devoted oneself to work the first performance loop and the second performance loop of state；First performance loop at least includes the evaporation
Device, the first compressor and condenser；Second performance loop at least includes the evaporator, the second compressor and condenser；
The condensing agent circulated is equipped with first performance loop and second performance loop.
Air-conditioning system described in the utility model for container, it is by setting at least two compressors switchably
Work so that when one of performance loop breaks down, can automatically and quickly be switched in another performance loop,
So as to ensure that all the time at least one performance loop can normally devote oneself to work state, and compressor fault maintenance is not interfered with
Or time-based maintenance.Because in complicated harsh use environment, compressor easily breaks down, once there is event in compressor
Barrier, then whole air-conditioning system will be unable to normal work, also just can not efficient dominating set vanning internal work area environment temperature, especially
It is in the case of container ambient temperature very high (such as 53 DEG C), and the temperature of internal container workspace environment will be fast
Speed rise, the daily life system quality for personnel is very unfavorable.And air-conditioning system of the present utility model is when there is compressor fault,
As long as also one performance loop is normal, it is possible to continues to the normal operation of air-conditioning system, and does not interfere with compressor
Trouble hunting or time-based maintenance, so as to meet the demand of the high-quality life work and rest of personnel.Therefore, sky of the present utility model
Adjusting system can apply to container especially pressurised containers, and can be suitably used for complicated harsh use environment, can especially be applicable

Condensing agent, then flows through the first stop valve 11 and the condensing agent gas for being compressed into HTHP is sucked by the first compressor 12, it
After flow through the first check valve 13 and be expelled to condenser 3 and be cooled to condensing agent liquid, then throttled by valve member group 4 and expansion valve 5
Decompression, finally the condensing agent as low-temp low-pressure sends evaporator 1 back to.And so on circulate, maintain container pressurized operation area C to set
Constant temperature degree.
When the first performance loop A, which breaks down, can not continue running, the first stop valve 11 is closed, and the second stop valve 21 is opened
Open.Now the second performance loop B devotes oneself to work state, and condensing agent absorbs container pressurized operation area C air in evaporator 1
Heat, flashes to gaseous state condensing agent, then flows through the second stop valve 21 and is compressed into HTHP by the suction of the second compressor 22
Condensing agent gas, the second check valve 23 flowed through afterwards be expelled to condenser 3 and be cooled to condensing agent liquid, then by valve member group
4 and the reducing pressure by regulating flow of expansion valve 5, finally the condensing agent as low-temp low-pressure send evaporator 1 back to, and so on circulate, maintain packaging
Case pressurized operation area C design temperatures.
Vice versa, when the second performance loop B breaks down, and air-conditioning system is by opening the first stop valve 11, closing
Second stop valve 21 switches the first performance loop A to working condition, so as to persistently maintain the normal operation of air-conditioning system, does not influence
Compressor fault is overhauled or time-based maintenance, meets the demand of the high-quality life work and rest of personnel.
It should be noted that the described above of disclosed embodiment enables professional and technical personnel in the field to show and easy
Insight for present embodiment carry out it is a variety of it is similar change and modifications, it is this it is similar change be that those skilled in the art can be from this reality
All deformations just associated are immediately arrived at or be easy to new disclosure, all should belong to protection of the present utility model
Scope.Therefore the utility model will not be limited by the embodiment.
