The regulation valve control device realizes the dynamic regulation on the coil pipe flow rate in the air conditioning box, and the energy sources are greatly saved.
Description
Technical field
The utility model relates to the central air-conditioning technical field, and is special relevant with the control valve control device of air-conditioning box in the central air-conditioning centralized control system.
Background technology
Air-conditioning box in the central air-conditioning is wherein a kind of equipment of a central air-conditioning end, and chilled water or hot water are transported in the air-conditioning box coil pipe by the central air-conditioning pipe-line system, is transported in each zone by the unification of air-conditioning box wind pipe again.
General main coil pipe section, fan section, the air return section of comprising in the air-conditioning box, the recirculated water of central air-conditioning is sent use by blower fan with cold wind or hot blast then through the coil pipe section.And in the general central air-conditioning, after the air-conditioning box startup work, the flow in the coil pipe is changeless, and the heat supply of regional space or cooling maintain in the same level all the time, can't flexible modulation.
And come into operation and test according to actual now, the terminal operating position of central air-conditioning is in dynamic change always, promptly change along with the change of environment, such as different round the clock, season, difference or flow of the people were different and change constantly, cause single energy supply pattern to mate mutually thus, can cause the serious waste of resource like this with dynamic behaviour in service.
Given this, the inventor designs the control valve control device of air-conditioning box in a kind of central air-conditioning centralized control system, and this case produces thus.
The utility model content
The utility model main purpose is to provide the control valve control device of air-conditioning box in a kind of central air-conditioning centralized control system, realizes the dynamic adjustments of coil pipe flow in the air-conditioning box, saves the energy significantly.
For achieving the above object, the technical solution adopted in the utility model is:
The control valve control device of air-conditioning box in the central air-conditioning centralized control system comprises central air-conditioning centralized control system, coil pipe control valve, temperature sensor; The coil pipe control valve is installed on the air-conditioning box pipe-line system return pipe; Temperature sensor is arranged in the air-conditioning box return air inlet, and detected return air temperature signal is sent in the central air-conditioning centralized control system; The control end of central air-conditioning centralized control system connects the coil pipe control valve.
Described central air-conditioning centralized control system inside has set in advance the temperature initial value.
After adopting such scheme, the utility model can be grasped terminal air-conditioning operating position according to the detected return air inlet temperature of temperature sensor, thereby can adjust the unlatching size of control valve by the central air-conditioning centralized control system, make circulating water flow change, adjust energy consumption.
The utility model has been realized dynamically controlling to adjust the size of valve flow according to the actual end operating position, thereby saves the energy of central air-conditioning centralized control system, avoids the single form energy supply like this, reduces the central air-conditioning energy consumption greatly.
Description of drawings
Fig. 1 is the utility model preferred embodiment structural representation;
Fig. 2 is the electrical control module diagram of the utility model preferred embodiment.
The specific embodiment
In conjunction with the accompanying drawings, preferred embodiment is described in further details to the utility model.
As shown in Figure 1 and Figure 2, the parts that are mainly concerned with of the utility model preferred embodiment comprise central air-conditioning centralized control system 1, coil pipe control valve 2, temperature sensor 3, air-conditioning box 4.
Central air-conditioning centralized control system 1 can adopt original control system in the central air-conditioning, and its internal structure is an equipment commonly used in the industry, does not do here and gives unnecessary details.
Air-conditioning box 4 is exactly the wherein a kind of terminal form in the central air-conditioning, mainly comprises coil pipe section 41 and fan section 42.Coil pipe section 41 has air-conditioning box pipe-line system return pipe 43 and air-conditioning box pipe-line system water inlet pipe 44, and fan section 42 comprises air outlet 45 and return air inlet 46.The recirculated water of central air-conditioning is by the driving of circulation-water pump electric machine, from 43 inputs of air-conditioning box pipe-line system return pipe, from 44 outputs of air-conditioning box pipe-line system water inlet pipe.Blower fan in the fan section 42 will be sent from air outlet 45 through the wind regime after the coil pipe heat exchange, and room air is drawn back from return air inlet 46 again after exchanging, and recycles.
In order to grasp terminal operating position constantly, temperature sensor 3 is set in return air inlet 46, detect the user mode of terminal air-conditioning, and the temperature signal that will detect is sent in the central air-conditioning centralized control system 1.Usually inside is provided with a temperature initial value in central air-conditioning centralized control system 1, and temperature sensor 3 detected temperature signals and temperature initial value compare, and forms a temperature difference, regulates coil pipe control valve 2 according to the temperature difference.
Coil pipe control valve 2 is motor regulated valves, is installed on the air-conditioning box pipe-line system return pipe 43, and the control end of the central centralized control system 1 of coil pipe control valve 2 connections, thereby the operating frequency of control circulation-water pump electric machine.
During the utility model work, when testing process, temperature sensor 3 detected temperatures of return air inlet 46 are sent to this temperature signal in the central air-conditioning centralized control system 1, compare with the temperature inside initial value, form the temperature difference, realize having level to regulate according to this temperature approach.Start-up control when the detected temperature difference is less than 5 ℃ in the present embodiment, when the temperature difference is 4 ℃, the state that control coil pipe control valve 2 is opened 100%; When the temperature difference is 3 ℃, the state that control coil pipe control valve 2 is opened 75%; When the temperature difference is 2 ℃, the state that control coil pipe control valve 2 is opened 50%; When the temperature difference is 1 ℃, the state that control coil pipe control valve 2 is opened 25%; When the temperature difference is 0 ℃, the state that control coil pipe control valve 2 is opened 0%.
The utility model has been realized according to the dynamic behaviour in service of end, the Flow-rate adjustment of coming recirculated water in the flexible modulation air-conditioning box, energy-conserving and environment-protective.The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
