The first capable load, and returning to the refrigeration equipment loads its compressor according to the first load；
Step 2, in the loading procedure, the related data of refrigeration equipment is obtained in real time；
Step 3, the second load for maintaining the compressor of user's required temperature is calculated, and return to the refrigeration equipment to make compressor
Compressor is unloaded according to the second load.
It is specifically included specifically, the step 1 is analyzed and processed the related data: the related data is carried out
Classification, will affect compressor and the relevant parameter of unloading is added to be classified as one kind, and obtain the first load by the relevant parameter.It is described
Relevant parameter include inflow temperature, leaving water temperature, the operating load of refrigeration equipment unit, current environmental temperature, target temperature with
And the parameter of compressor itself.
Preferably, first load is the corresponding compressor load of best Energy Efficiency Ratio.The best Energy Efficiency Ratio is 40%-
70%。
Preferably, the step 2 further includes the difference of real-time analysis current environmental temperature and target temperature, controls the pressure
The loading velocity of contracting machine is positively correlated the loading velocity and the difference.
Preferably, it before compressor reaches the first load, calculates second load and prepares to unload.
In an Application Example, the refrigeration equipment includes air-conditioning.
The invention also provides a kind of server, the compressor for executing in above-mentioned technical proposal adds Unloading Control method
Unloading is added to control on compressor.
Preferably, the server is built using hadoop cluster.
The present invention obtains the first load and the second load, according to two by acquisition, analysis to unit real-time running data
Kind of load come in real time to compressor plus unloading control, the mode that a fixed value is arranged than in the prior art is more slow
With, and the present invention can also utilize the setting of the logic based on big data and the integration of algorithm, obtain optimal compressor and add
Discharge rate control program, control machine set compressor adds discharge rate.
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 flow chart of the invention.
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, one embodiment of the invention propose compressor plus Unloading Control method, by with refrigeration equipment into
Row communication, obtains the related data of refrigeration equipment, then classifies to related data, wherein unloading will be added related with compressor
Relevant parameter be divided into one kind, specific relevant parameter may include the operation of inflow temperature, leaving water temperature, refrigeration equipment unit
The parameter etc. of load, current environmental temperature, target temperature and compressor itself.
Then logic and algorithm based on big data are utilized, relevant parameter is handled, obtains compressor stable operation
The first load, and returning to refrigeration equipment loads its compressor according to the first load.In the present embodiment, first is negative
Lotus is the corresponding compressor load of best Energy Efficiency Ratio, different according to compressor and unit situation, and usually best Energy Efficiency Ratio is
40%-70%。
During the loading process, it will continue to be communicated with refrigeration equipment, obtain the related data of refrigeration equipment in real time.
Then the second load of the compressor of user's required temperature is maintained according to these correlation data calculations, and returns to system
Cool equipment unloads compressor to compressor according to the second load.Make compressor more steady to reach one
Fixed plus uninstall process just calculates the second load and prepares to unload before compressor reaches the first load.It can be by counting greatly
According to logic and algorithm, calculate a critical value, allow compressor gently complete plus unloading, to promote entire unit
Operational efficiency and service life.
In the loading procedure of compressor, the difference of current environmental temperature and target temperature can also be analyzed in real time, is passed through
The difference controls the loading velocity of compressor, is positively correlated loading velocity and difference, specifically how to control equally can be with base
It obtains being suitble to the specific loading velocity of a compressor and the curved line relation of difference in the logic and algorithm of big data.
Refrigeration equipment of the invention includes air-conditioning, by 4G data transmission module built-in in refrigeration equipment unit, has been come
The monitoring and transmission of pairs of refrigeration equipment unit real-time running data.Real time data unit run using 4G transmission module into
Row timely returns, state parameter, environment temperature parameter, inlet and outlet temperature parameter, flag bit and all kinds of sensings including unit
The parameters such as the operation data of device.
The present invention, which also protects, executes the server that above-mentioned compressor adds Unloading Control method.The server can use
Hadoop cluster is built, and server is decrypted the data of unit passback back, compresses, parses, among message
Part is such as: kafka, flume component are sent to the data of parsing in Hadoop cluster, are saved in corresponding data warehouse,
Then data are cleaned, filters out some useless data.Server classifies the data that cleaning is completed, and will affect
Compressor adds the relevant parameter (such as: Inlet and outlet water real time temperature, unit operating load) of discharge rate to be classified as one kind, then transmits
To in the logic and algorithm of compressor plus discharge rate control program, is timely analyzed and calculated, by compressor plus unloaded
The logic of speed-control scheme and the processing and analysis of algorithm are carried, show that a set of optimal compression machine for being suitble to the unit adds unloading speed
