Abstract
The invention discloses an air-conditioning system convenient to control in a pharmaceutical industry. The air-conditioning system comprises a frequency changer, the frequency changer is connected with an air blower, the air blower is connected with a production workshop, and a control device is arranged on the frequency changer. The air-conditioning system convenient to control in the pharmaceutical industry is simple in structure, uses the frequency changer to regulate air blown by the air blower, conducts constant temperature setting of the temperature of the air while changing the air inside the production workshop, controls a frequency changing process, and keeps the temperature of the air inside the production workshop constant.
Description
Technical field
The present invention relates to a kind of air-conditioning system, especially relate to a kind of air-conditioning system of the pharmaceutical industry of being convenient to control, be applicable to the fields such as medicine, chemical industry, food.
Background technology
Trans-corporation by large-scale union and merger and international capital market running, sets up global production and sales network in order to enhance our international competitiveness, and extends volume growth.Trans-corporation is increasing on the impact of World Economics, makes the rival of China's pharmaceuticals industry ever more powerful that becomes.The internationalization of the domestic market and intellectual property protection are stricter, make market competition become more direct and of vital importance.Worldwide economic restructuring makes the developing countries such as India become the powerful rival of China.The develop rapidly of modern biotechnology will produce revolutionary impact to medical industry, to the in-depth of difficult diseases understanding, and the appearance of numerous new bio technical agents, rebuilding traditional industry etc. with biotechnology all will greatly change the looks of medical industry.World Developed Countries utilizes the advantage on fund, technology, market, implements monopolization, and China's medicine will launch at biological technical field the competition of a new round with developed country.
Along with being filled with of back to nature trend, the international market increases day by day to the demand of natural drug.At present cosmopolitian plant goods sales volume is nearly 30,000,000,000 dollars, and wherein the natural drug sales volume has reached 16,000,000,000 dollars, and with the speed increase in year 10%.For this reason, various countries competitively adopt modern technologies research and development traditional medicine, seize international natural drug market.This explores world market for China's Chinese medicine opportunity is provided.China has possessed richer medical industry material base, and the proportion that the medical industry gross output value accounts for GDP is 2.7%.The large class bulk drug output such as vitamin C, penicillin Nacl, paracetamol ranks first in the world, and the preparation production capacity ranks first in the world.China's medicine export amount accounts for 2% of global medicine export amount, but the average annual growth rate of Chinese medicine outlet has reached more than 20%, and the international average level is 16%.Meanwhile, Chinese drug market status constantly promotes, the share that accounts for world's drug market by 1978 0.88% rise to 2008 8.25%.In the production process of workshop, because raw material has smell, cause shop personnel's health to suffer damage, so need to take a breath to the air in the workshop.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of air-conditioning system of the pharmaceutical industry of being convenient to control is provided, this air-conditioning system is simple in structure, the wind that utilizes frequency converter that pressure fan is sent is regulated, in the process that the air of workshop is changed, also the temperature of air is carried out constant temperature and set, the process of frequency conversion is controlled, guarantee stationary temperature.
Purpose of the present invention is achieved through the following technical solutions: the air-conditioning system of the pharmaceutical industry of being convenient to control, comprise frequency converter, and described frequency converter is connected with pressure fan, and described pressure fan is connected with workshop, is provided with control device on described frequency converter.
Also comprise the pressure-fired sensor that is arranged in workshop, described pressure-fired sensor is connected with frequency converter.
Pass through connection between described pressure-fired sensor and frequency converter.
Be provided with the PID adjuster in described frequency converter.
Pass through connection between described frequency converter and pressure fan.
Be provided with pipeline between described pressure fan and workshop, described pipe ends is connected with workshop with pressure fan respectively.
Described workshop is provided with ventilating fan.
In sum, the invention has the beneficial effects as follows: this air-conditioning system is simple in structure, the wind that utilizes frequency converter that pressure fan is sent is regulated, in the process that the air of workshop is changed, also the temperature of air being carried out constant temperature sets, process to frequency conversion is controlled, and guarantees stationary temperature.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment 1:
As shown in Figure 1, the air-conditioning system of the pharmaceutical industry of being convenient to control comprises frequency converter, described frequency converter is connected with pressure fan, described pressure fan is connected with workshop, also comprises the pressure-fired sensor that is arranged in workshop, and described pressure-fired sensor is connected with frequency converter.Frequency converter is to utilize the on-off action of power semiconductor device power frequency supply to be transformed to the electric energy control device of another frequency, can realize soft start, frequency control, raising running accuracy, change power factor, overcurrent/overvoltage/functions such as overload protection to AC induction motor.
Pass through connection between described pressure-fired sensor and frequency converter.The variation of workshop Air pressure or temperature, the induction by the pressure-fired sensor feeds back in frequency converter, and frequency converter keeps workshop in the environment of a constant temperature according to the program of setting in advance.
Be provided with the PID adjuster in described frequency converter.Adjuster is as the intelligent automatic control system, and automatic control system can be divided into open-loop control system and closed-loop control system.A control system comprises Kong Qi ﹑ processed sensor, transmitter, executing agency, input/output interface.The output of controller is added on controlled system through output interface, executing agency; The controlled volume of control system, through sensor, transmitter is delivered to controller by input interface.
Pass through connection between described frequency converter and pressure fan.Be provided with pipeline between described pressure fan and workshop, described pipe ends is connected with workshop with pressure fan respectively.
Described workshop is provided with ventilating fan.When passing into a large amount of air after workshop, due to the workshop of medicine for fear of dust, all to adopt sealed environment, the pressure of workshop inside can become greatly, and operating personnel's health is impacted, and therefore need to carry out pressure balance, by ventilating fan is set, can make the atmospheric pressure of workshop keep mean value, the medicine odor dispersion in workshop can be gone out simultaneously, guarantee operating personnel's safety.
Embodiment 2:
The structure of the present embodiment and embodiment 1 is basic identical, and its difference only is: be provided with control device on described frequency converter.In long neglected and in disrepair or other situations, easily cause controlling malfunctioning due to the self-checking device in frequency converter, by control device is set, operating personnel manually control, and have guaranteed the continuity of work, and safety guarantee is provided, and have extended service life.
Take aforesaid way, just can realize preferably the present invention.
