Abstract
The invention discloses fouling judgment method, the refrigeration system of a kind of refrigerant conduction pipeline, whether the wherein fouling judgment method of refrigerant conduction pipeline reaches preset threshold value and determines whether fouling by the inside pipe wall and the temperature difference of pipe outer wall that judges refrigerant conduction pipeline.This method is simple and easy, and can pipeline to refrigeration equipment whether fouling can carry out early warning in time, be conducive to the care and maintenance of air-conditioning.
Description
Technical field
The present invention relates to refrigeration equipments more particularly to refrigeration equipment with the fouling judgment method of its refrigerant conduction pipeline.
Background technique
With being continuously increased for population, levels of substance is continuously improved, and Living consumption, which is gradually increased, meets people couple
Hot summer needs nice and cool physiological environment.Consumer is increasing to the demand of air-conditioning.But air-conditioning is used for a long time
It is found that air-conditioning is after the regular hour that works, cooling, heating effect can be decreased obviously, and be likely to require at this time pair
Air-conditioning is cleaned, the fouling etc. in pipeline to remove air-conditioning, but user do not have air-conditioning professional knowledge generally can not and
Shi Faxian air-conditioning needs to clear up, and the after-sale service of producer due to lack data support can only periodic cleaning, this leads to pipeline not
It can be cleared up or excessively be cleared up in time.
Summary of the invention
In order to solve the problems, such as that the fouling of refrigerant conduction pipeline in the prior art cannot find that the invention proposes one in time
Whether the fouling judgment method of kind of refrigerant conduction pipeline is arrived by the inside pipe wall and the temperature difference of pipe outer wall that judges refrigerant conduction pipeline
Fouling is determined whether up to preset threshold value.
In a specific embodiment, operation data, the remote server are sent from refrigeration equipment to remote server
The threshold value is obtained according to the operation data.Specifically, the remote server is based on collected all refrigeration equipments
Operation data is formed by data acquisition system and carries out data mining, obtains the threshold value.
Wherein operation data may include inside pipe wall temperature and tube wall temperature, or directly include inside pipe wall temperature and pipe
The temperature difference of outside wall temperature.
It can be compared with the threshold value to determine whether tying by the remote server according to the operation data received
The threshold value can be sent to refrigeration equipment with the remote server by dirt, by refrigeration equipment according to itself operation data
It is compared with threshold value to determine whether fouling.
If it is determined that fouling, then send early warning prompting.The early warning prompting includes: to send short message, and/or life to maintenance staff
Research staff is sent at refrigerant conduction Incrustation of pipe report.
Specifically, the refrigeration equipment is communicated by 4G network with remote server.The refrigeration equipment includes sky
Adjust device.
The invention also provides a kind of refrigeration systems of fouling judgment method by adopting the above technical scheme.
The present invention is by being monitored the temperature difference between the inside and outside wall of refrigeration equipment pipeline, to learn whether pipeline is tied
Dirt needs to clear up, and can make early warning in advance, informs maintenance staff, makes house calls in advance, for air-conditioning itself, be conducive to sky
The raising of line efficiency is allocated and transported, and the air-conditioning service life can be extended；For user, air-conditioning uses power saving of more saving worry.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:.
Fig. 1 is the architecture diagram of inventive refrigeration system.
Specific embodiment
The principle and optimum embodiment that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figure 1, refrigeration system of the invention includes refrigeration equipment and remote server, in the present embodiment, refrigeration
Equipment is communicated by 4G network with remote server, and remote server collects the operation data of all refrigeration equipments, carrys out shape
At the data acquisition system of magnanimity.The operation data may include inside pipe wall temperature and tube wall temperature, then by remote server Lai
The temperature difference between the inside and outside wall of computer tube, the operation data can also be directly being calculated by refrigeration equipment and be sent to remote
The inside pipe wall temperature of journey server and the temperature difference of tube wall temperature.In addition to this, operation data can also include the state of unit
The parameters such as parameter, humidity parameter, temperature parameter, pressure parameter, current parameters, flag bit.
Remote server either can form one by all refrigeration equipments based on above-mentioned any operation data
Operation data is formed by the data acquisition system of magnanimity, and carries out data mining, obtains suitable threshold value.
Once the refrigerant when refrigeration equipment conducts pipeline fouling, it will the biggish temperature difference is generated in inside pipe wall and pipe outer wall,
The present invention is by judging that refrigerant conducts the inside pipe wall of pipeline and whether the temperature difference of pipe outer wall reaches preset threshold value and determine whether
Fouling, this method very simple is effective, and low in cost.
Remote server can compare the temperature difference between the inside and outside wall of pipe and threshold value to determine the refrigerant of corresponding refrigeration equipment
Conduct pipeline whether fouling, can also be and threshold value is sent to refrigeration equipment by remote server, by refrigeration equipment come comparison temperature
Difference and threshold value, therefore, it is determined that refrigeration equipment refrigerant conduction pipeline whether fouling.
Originally, it manages inside and outside wall all to clean very much, the difference for managing interior temperature and the outer temperature of pipe is smaller, illustrates no scale formation.
With prolonged use, inner wall will appear scale, it may appear that the difference of temperature and the outer temperature of pipe becomes larger in managing, when judgement is freezed
When the refrigerant of equipment conducts Incrustation of pipe, early warning prompting is carried out, maintenance staff and/or research staff are pushed to.For maintenance people
Member can inform where maintenance staff safeguard by the way of sending short message；For air-conditioning developer, can go out
A more detailed PDF report, provides help to the improvement of subsequent unit research and development.
Refrigeration equipment of the invention includes air-conditioning.Business air conditioner volume is larger, is generally placed upon basement or area is larger
Space in, data unit operation is sent back to by 4G network, in order to guarantee data security and terminate flow, unit issues long-range clothes
The data of business device are encrypted and are compressed, so, remote server receives the operation data that unit is sent back, right first
Data are carried out into decryption, compression.Specifically, remote server includes interface server and hadoop cluster.Interface server benefit
Data are received with message-oriented middleware to transmit data in hadoop cluster data warehouse and stored using flume component.
In a specific embodiment, totally 15 servers, 2 management nodes and 13 memory nodes, data store hadoop cluster
On HDFS.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
