According to the pressure that the pressure sensor and the set point of difference, control of public space and office air shaft stress. Main exhaust air volume, according to the operation of the new fan, and automatically adjust accordingly. * 對于空調(diào)器內(nèi)的加濕器，根據(jù)室內(nèi)的相對溫度，控制一次風(fēng)的加濕量。根據(jù)壓力傳感器所測的壓力與設(shè)定值的差值，控制公共空間和辦公新風(fēng)豎井的壓力定。但由于定靜壓控制的變風(fēng)量系統(tǒng)，其 空調(diào)器的風(fēng)機(jī)調(diào)節(jié)與末端裝置的控制無直接聯(lián)系，故該系統(tǒng)控制方法比較簡單，運(yùn)行可靠，適合于較大的變風(fēng)量空調(diào)系統(tǒng)的場合。 In small scale variable volume air conditioning system can be used in variable static pressure control using variable static pressure control system required in total duct static pressure sensors, but in the end of the variable air volume device set in the valve opening sensor, but in the open degree of vav terminal devices, the judgment and calculation to adjust a air conditioner fan frequency converter in wind, made with the minimum static pressure value at the end of the installation of the valve is in open form, made with the minimum static pressure value at the end of the installation of the valve is in open state, so that we can minimize the static balance of the fan running, saving energy consumption of the fan. * 定靜壓法的變風(fēng)量系統(tǒng)控制 * static pressure method of variable air volume control system 在通常的變風(fēng)量空調(diào)系統(tǒng)中，一般設(shè)計(jì)采用定靜壓控制法。根據(jù)感溫器所測的溫度與室內(nèi)溫度設(shè)定值的差值，控制該區(qū)域的末端裝置內(nèi)一次風(fēng)電電動(dòng)機(jī)風(fēng)閥的開啟度，對于周邊再加熱變風(fēng)箱，當(dāng)室溫下降，風(fēng)閥關(guān)至最小風(fēng)量值時(shí)，啟動(dòng)再加熱器，提供外區(qū)空調(diào)所需的熱負(fù)荷。如在高大公共空間設(shè)置空周邊熱水采暖設(shè)備，則由其周邊采暖區(qū)域的溫度控制設(shè)在熱水采暖設(shè)備回水管上的電動(dòng)二通比例式調(diào)節(jié)閥。 The normal operation of the air conditioning system relies mainly on the automatic control system, the automatic control system and the whole building automation management system of puter connected to the central monitoring and control. In general in the building of variable air volume air conditioning system, including the following broad requirements below. * 水閥的調(diào)節(jié) * the adjustment of the water valve 在個(gè)別定風(fēng)量系統(tǒng)中，由回風(fēng)溫度控制安裝在冷熱水回水管上 的電動(dòng)二通比例式調(diào)節(jié)閥。 In some design examples, often ignored the floor inside the exhaust pipe interface, set the constant air volume controller, and the air exhaust and toilet exhaust into an exhaust system, for this kind of design, while the exhaust fan is still the frequency control of motor speed control, to achieve the building of the new, the exhaust of the aggregate balance. But for each floor, each floor exhaust air exhaust system theory is evenly distributed, and the rest of the air conditioning running the floor of the assigned to reduce exhaust air, due to high positive pressure room. In the lobby and other public Spaces of the building air conditioning design, generally adopts traditional of air output, the new air volume air conditioning system. Considering the winter air conditioner is running, for the building of high building, will produce larger heat up effect, so as to produce larger negative pressure air conditioning in the cause of the runtime. Therefore, the lobby and other public space of air conditioning can consider to use air output, new air volume system, air conditioning fresh air is provided by frequency conversion speed regulating of air blower, by adjusting the amount of fresh air into the indoor air conditioning runtime to ensure that the different season, set positive pressure (public space indoor pressure setting shall meet the small new the required air volume). 自動(dòng)控制 6, the automatic control 空調(diào)系統(tǒng)的正常運(yùn)行主 要依靠自動(dòng)控制系統(tǒng)，這套自動(dòng)控制系統(tǒng)與整個(gè)大樓的自動(dòng)化管理系統(tǒng)的電腦相連接，實(shí)現(xiàn)中央監(jiān)控和調(diào)節(jié)?？紤]到冬季空調(diào)運(yùn)行時(shí)，對于樓體較高的大樓，會產(chǎn)生較大的熱升效應(yīng)，從而造成大堂冬季空調(diào)運(yùn)行時(shí)產(chǎn)生較大的負(fù)壓。但對于每個(gè)樓層而言，排風(fēng)系統(tǒng)理論上各樓層排風(fēng)量是平均分配的，而其馀空調(diào)運(yùn)行的樓層所分配到的排風(fēng)量減少，造成房間過高的正壓。當(dāng)然，大樓內(nèi)還 需設(shè)置一套廁所不間斷定風(fēng)量排風(fēng)系統(tǒng)，保證廁所內(nèi)異味的排除。 Figure 5 is a typical variable air volume system economic operation. Mix the wind is used for air conditioning system, the new air volume is according to the air distribution in each room. That is to say, even if the total has met the requirement of the new air volume, also in the room will have the problem of insufficient fresh air, the variable air volume system, due to the requirement into the room, a total new air volume will be increased, and in some time may be more than to send air volume air conditioning needs. Therefore, can consider this, under the certain new air volume, total carbon content in the return air not excessive, can use the return air to reduce the total new air volume. Here is air conditioning system is running, blowers according to the train air conditioning load is determined, new fan is determined according to the air quality of the return air provided by the new air volume, while exhaust fan according to room for positive pressure value matches the new fan running. During the transition season, the new fan or the turning of the exhaust fan air volume adjustment to maintain certain new return air temperature, the wind that is filled using the low humidity of outdoor air cooling to reduce the opening time of the cooler. But in actual use, such as building standard layer independent setting a variable air volume air conditioning time. But in actual use, such as building standard layer independent setting a variable air volume air conditioning system, it needs to be set on each floor two frequency control of motor speed blower fan and exhaust fan (new). This will inevitably increase the each of the air conditioning room space, also greatly increase the initial investment cost. In order to ensure the quality of indoor air, system operation, is through the dete
