The air handling unit fan is connected with a frequency converter, the temperature sensor is installed inside a room for detecting indoor temperature and transmitting detected data to the central air-conditioning centralized control system, and simultaneously the output end of the central air-conditioning centralized control system is connected with the frequency converter. The electric motor frequency control device realizes dynamic adjustment of working frequency of the air handling unit fan according to using condition of terminals and saves energy consumption of a central air-conditioner.
Description
Technical field
The utility model relates to the central air-conditioning technology, and is special relevant with air-conditioning box motor frequency conversion control device in a kind of 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 to by the central air-conditioning pipe-line system and carry out heat exchange in the air-conditioning box coil pipe, are 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 with cold wind or hot blast by airduct by blower fan then through the coil pipe section.And in the general central air-conditioning, after the air-conditioning box startup work, the operating frequency of blower fan is constant all the time, 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 indoor environment temperature, 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 air-conditioning box motor frequency conversion control device 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 air-conditioning box motor frequency conversion control device in a kind of central air-conditioning centralized control system, realizes the dynamic adjustments of blower fan operating frequency in the air-conditioning box, saves the energy significantly.
For achieving the above object, the technical solution adopted in the utility model is:
Air-conditioning box motor frequency conversion control device in the central air-conditioning centralized control system comprises central air-conditioning centralized control system, air-conditioning box blower fan, temperature sensor; The air-conditioning box blower fan connects frequency converter, and temperature sensor is installed on indoor, detects indoor temperature, and these data are sent in the central air-conditioning centralized control system, and the output of central air-conditioning centralized control system connects frequency converter simultaneously.
Described central air-conditioning centralized control system inside is provided with desired temperature.
After adopting such scheme, the environment temperature of the utility model in constantly in the sensing chamber, and this ambient temperature signal fed back to central air-conditioning centralized control system inside, thereby adjust air-conditioning box fanman working frequency by the central air-conditioning centralized control system according to temperature signal, make the work of air-conditioning box fan frequency conversion, adjust the size of energy supply.
The utility model has been realized dynamically controlling the size of fanman's working frequency 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.
The parts that the utility model relates generally to comprise central air-conditioning centralized control system 1, temperature sensor 2, air-conditioning box blower fan 3, air-conditioning box 4, frequency converter 5.
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 end-equipment in the central air-conditioning, mainly comprises coil pipe section 41 and fan section 42, and air-conditioning box blower fan 3 is installed in fan section 42.Coil pipe section 41 has recirculated water input 43 and recirculated water output 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 recirculated water input, from 44 outputs of recirculated water output.Air-conditioning box blower fan 3 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.
Improvement of the present utility model is exactly to connect a frequency converter 5 on air-conditioning box blower fan 3, and the control end of central air-conditioning centralized control system 1 connects frequency converter 5, and input is mounted on indoor temperature sensor 2.Temperature sensor 2 is the temperature in the sensing chamber constantly, the formation temperature signal feedback is to central air-conditioning centralized control system 1 inside, and in central air-conditioning centralized control system 1, preestablished a desired temperature, relatively obtain the temperature difference by two temperature, export control according to 1 pair of frequency converter 5 of temperature difference central air-conditioning centralized control system, and frequency converter 5 is connected on the air-conditioning box blower fan 3, through frequency conversion, make the operating frequency of air-conditioning box blower fan 3 change, realize Energy Saving Control.
The utility model has been realized according to the dynamic behaviour in service of end, the operating frequency of coming air-conditioning box blower fan 3 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.
