Abstract
The present invention relates to a kind of constant-temperature control method of water-cooled central air-conditioning, the control hysteresis time of described water-cooled central air-conditioning is t; Comprise the following steps: the operational factor of central air-conditioning when keeping indoor temperature to be pre-set constant temperature when 1) measuring different outdoor temperatures by experiment, obtains the control strategy of described central air-conditioning; 2) the Temperature prediction value of meteorological department and the difference table of actual outdoor temperature is recorded in advance; 3) finding step 2) difference table that obtains, obtain the outdoor temperature predicted value after control hysteresis time t from the Temperature prediction value of meteorological department, and perform the corresponding control strategy that step 1) obtains.The present invention adjusts temperature control strategy in advance corresponding lag time, indoor temperature can be kept relatively stablely to be pre-set constant temperature, reach and make central air-conditioning farthest energy-conservation.
Description
Technical field
The present invention relates to a kind of humidity control system constant-temperature control method of water-cooled central air-conditioning, belong to Monitoring and Controlling technical field.
Background technology
The water system of water-cooled central air-conditioning due to pipeline long, cycle period is long, and specific heat of water holds the objective circumstances such as larger, therefore, both having there is the transfer lag of cold and hot amount in central air conditioning water system, there is again the control lag of cold and hot amount simultaneously, belong to typical time lag system.To this " delayed " phenomenon of central air conditioning water system, the difficulty of control is uncontrollability and the fluctuation of control procedure.After control instruction sends, a cycle period of water system not yet terminates, or controlled variable (water temperature etc.) does not also have enough time to respond, and system load demand or operating condition may there occurs change again.After control system collects new change, do " delayed " and control, new control instruction can be sent again, thus cause system cloud gray model disorder or fluctuation, be difficult to the control overflow reached desired by user.Meanwhile, exactly because also this time stickiness, system cannot be realized " cooling on demand ", wastes energy consumption.
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides a kind of constant-temperature control method of energy-conservation water-cooled central air-conditioning.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of constant-temperature control method of water-cooled central air-conditioning, and the control hysteresis time of described water-cooled central air-conditioning is t; Comprise the following steps:
1) when keeping indoor temperature to be pre-set constant temperature when measuring different outdoor temperatures by experiment, the operational factor of central air-conditioning, obtains the control strategy of described central air-conditioning;
2) the Temperature prediction value of meteorological department and the difference table of actual outdoor temperature is recorded in advance;
3) finding step 2) difference table that obtains, obtain the outdoor temperature predicted value after control hysteresis time t from the Temperature prediction value of meteorological department, and perform the corresponding control strategy that step 1) obtains.
Preferably, step 2 of the present invention) in, when recording actual outdoor temperature and exceeding pre-set constant temperature, namely calculate the Temperature prediction value of meteorological department and the difference of actual outdoor temperature, the mean value getting more than 100 times is saved in the Temperature prediction value of meteorological department and the difference table of actual outdoor temperature.
Instant invention overcomes time lag sex chromosome mosaicism during water-cooled central air-conditioning adjustment temperature in prior art, provide a kind of temperature adjusting method combined with the temperature prediction value of meteorological department based on actual measurement data, in prior art, the temperature prediction value of meteorological department is quite accurate, and its predicted value can be revised in real time by meteorological department, by both combinations, adjust temperature control strategy corresponding lag time in advance, indoor temperature can be kept relatively stablely to be pre-set constant temperature, to reach and make central air-conditioning farthest energy-conservation.
Detailed description of the invention
Embodiment
The constant-temperature control method of the water-cooled central air-conditioning of the present embodiment, the control hysteresis time of described water-cooled central air-conditioning is t; Comprise the following steps:
1) when keeping indoor temperature to be pre-set constant temperature when measuring different outdoor temperatures by experiment, the operational factor of central air-conditioning, obtains the control strategy of described central air-conditioning;
2) the Temperature prediction value of meteorological department and the difference table of actual outdoor temperature is recorded in advance;
3) finding step 2) difference table that obtains, obtain the outdoor temperature predicted value after control hysteresis time t from the Temperature prediction value of meteorological department, and perform the corresponding control strategy that step 1) obtains.
The present invention, in measurement outdoor temperature, adopts the outdoor temperature of shady spot, thus the comparatively big error that sun direct projection can be avoided to cause, reduce thermostatically controlled fluctuation.
Preferably, step 2 of the present invention) in, when recording actual outdoor temperature and exceeding pre-set constant temperature, namely calculate the Temperature prediction value of meteorological department and the difference of actual outdoor temperature, get 100 mean values and be saved in the Temperature prediction value of meteorological department and the difference table of actual outdoor temperature.
The present invention is not limited to above-described embodiment, and all employings are equal to the technical scheme of replacing and being formed in addition, all drop in the protection domain of application claims.
