Description
Technical field
It is exactly a kind of based on the big of Local cooling equipment the present invention relates to a kind of cooling system failure countermeasure
Type cooling system is met an urgent need failure recovery method.
Background technology
At present in daily production and living, large-scale cooling system has extremely wide application, and makes to meet
With needs, current large-scale cooling system is often made of more integrated distributions or the synchronous operation of the cooling equipment of discrete distribution
, due to the factors such as equipment operating environment difference and equipment oneself factor difference, more coolings for constituting large-scale cooling system are set
One or several is often occurred in which in standby because failure is unable to operate normally or needs to reduce operation Power operation, therefore final
The operation stability for resulting in large-scale cooling system is severely impacted, simultaneously because the volume of each cooling equipment is larger, and
Cost is also relatively high, causes to cause in actual use large-scale cooling system often without corresponding failure stand-by equipment, because
This is caused currently after going out first equipment fault in large-scale cooling system, and there are larger scarce for refrigerating capacity when large size cooling system operation
Mouthful, and the other effective replies of object and remedial measure, and with the development and popularization of local cooling system technology, since part is cold
But running efficiency of system is high, and compact is flexible and convenient to use, therefore using local cooling system to large-scale cooling system failure
Urgent remedy is possibly realized, but still lacks in practical operation and effectively carried out to large-scale cooling system using Local cooling equipment
The specific implementation method remedied, therefore the promotion and application of this technology are seriously limited, for this present situation, there is an urgent need to open
The cooling system emergency failure recovery method of large size for sending out a kind of based on Local cooling equipment, to meet the need that actual production uses
It wants.
Invention content
A kind of large-scale cooling system based on Local cooling equipment is provided the object of the present invention is to provide the utility model to answer
Anxious failure recovery method.
In order to achieve the above object, the present invention provides the following technical solutions：
A kind of cooling system emergency failure recovery method of large size based on Local cooling equipment, includes the following steps：
The first step determines cooling system failure source and influence, former to the failure of the large-scale cooling system to break down first
Because being analyzed, at the same calculate the system failure it is out of service after caused by whole cooling system refrigerating capacity vacancy value；
Second step, Preliminary design remedy solutions for refrigeration, and the relevant information obtained according to the first step is tentatively selected for mending
The installation site for the partial cooling equipment rescued, the mode of operation power and the whole cooling system of access and position；
Third walks, and the operation of Local cooling equipment according to the calculated value of the first step, and combines the scheme specified by second step,
The installation positioning of Local cooling equipment is carried out first, and Local cooling equipment is connected to whole cooling system then, is finally started
Partial cooling equipment brings into operation, and gradually replaces the large-scale cooling system to break down, while the large size to break down is cooling
System-down is overhauled online；
4th step, fault recovery start the cooling system first after complete paired fault cools down maintenance of equipment or replaces,
And make its normal operation, it is then shut off Local cooling equipment, and disconnect the connection of Local cooling equipment and whole cooling system, most
Local cooling equipment is recycled afterwards.
5th step, equipment maintenance carry out whole maintenance to Local cooling equipment of the 4th step after operation and recycling, and
Repair and replacement are carried out to its vulnerable part and close to fault extreme parts, in case running again.
Further, it in the first step, when large-scale cooling system is because of failure partial loss of function, but remains to reduce work(
When rate is run, then still with cooling system situation out of service calculate and as second step when calculating refrigerating capacity vacancy value
The foundation of work, while cooling system refrigerating capacity missing values caused by failure loss of function part need to be separately calculated, and with this
Calculated value instructs the foundation of Local cooling equipment operation power as third step.
Further, in the 4th step, when carrying out fault recovery, the cooling system operation refrigeration of large size after repair
It is 1 to measure output power amplification and Local cooling equipment downtime refrigerating capacity amount of decrease ratio：1—5：1.
Operating method of the present invention is simple and practicable, versatility and highly practical, the effective specification large size cooling system of one side
On the other hand the quick means to save the situation of equipment fault efficiently can easily realize the exclusion to cooling system failure and remedy, have
Help improve the operation stability and reliability under cooling system is nonserviceabled.
