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
In danger zones such as such as desert, offshore oil drilling platforms.
Further, first performance loop is at least including the evaporator being sequentially connected, the first stop valve, first
Compressor, the first check valve, the condenser, valve member group and a heating power expansion valve;Second performance loop at least include according to
The evaporator, the second stop valve, the second compressor, the second check valve, the condenser, the valve member group and the institute of secondary connection
State heating power expansion valve;The heating power expansion valve is connected with the evaporator.
In such scheme, condensing agent absorbs the atmospheric heat in container pressurized operation area in evaporator, flashes to gaseous state
Condensing agent, then flows through the first or second stop valve and the condensing agent for being compressed into HTHP is sucked by the first or second compressor
Gas, flows through the first check valve and is expelled to condenser and be cooled to condensing agent liquid afterwards, then by valve member group and thermal expansion
Valve reducing pressure by regulating flow, finally the condensing agent as low-temp low-pressure send evaporator back to.And so on circulate, maintain internal container pressurization
The temperature of workspace setting.
Further, the flow direction of the air-out direction of the blower fan of the condenser and the condensing agent in the condenser
Set in convection current.

Because conventional aluminium paillon foil is easily by salt air corrosion, its suitable environment is extremely limited, can not especially be applicable high temperature and high salt
Mist area.Therefore using the V-type corrugated fin of copper foil, the corrosion resistance of condenser can be improved, while improving its radiating rate.
Further, in the air-conditioning system described in the utility model for container, the shell of the condenser is not
Become rusty outer steel shell.
In such scheme, it can preferably extend the service life of shell using stainless steel casing.
Further, in the above-mentioned air-conditioning system for container, the stainless steel casing is 316 stainless steel casings.
In such scheme, 316 stainless steels adapt to the severe use environment in high salt fog area, increase the service life.
Further, in the air-conditioning system described in the utility model for container, first compressor and/or
Two compressors are flexible vortex compressor.
In such scheme, the flexible vortex compressor has resistant to elevated temperatures feature so that container of the present utility model
Air-conditioning system is more suitable for the running in hot environment, it is ensured that the normal operation of performance loop and the comfort level of internal work personnel.
Further, the air-conditioning system of the container include a main circuit and one control circuit, the main circuit include according to
The breaker of secondary connection and the motor for controlling compressor and blower fan, the control circuit include the phase sequence being sequentially connected
Device, the time relay, dual-pressure controller, police instruction, temperature controller with exchange electric shock device;Wherein, the temperature controller will be default
