3.1 采用性能可靠的松下系列PLC為控制核心，所有輸入信號起停，保護都通過光電隔離輸入到PLC的輸入口，利用專用編程軟件，根據(jù)控制要求對PLC進行梯形圖編程，PLC輸出控制變頻器的起停。采用PLC控制后，可取消全部時間繼電器和中間繼電器，所有邏輯控制通過梯形圖軟編程，在不用改變控制線路的情況下，可隨時按控制要求修改程序，實現(xiàn)新的控制方案，靈活性相當(dāng)高；并具有強大的通訊接口，可與上位電腦相連，，實現(xiàn)遠程監(jiān)控，為將來聯(lián)網(wǎng)控制留 有接口，具有良好的擴展性，能與其他控制系統(tǒng)協(xié)調(diào)工作。變頻器調(diào)速控制電路簡單， 克服傳統(tǒng)線路易出故障的缺點，降低了事故發(fā)生。3.2 根據(jù)空調(diào)系統(tǒng)的實際情況，設(shè)計應(yīng)包括以下幾點：
（1）冷卻系統(tǒng)、冷凍系統(tǒng)各裝1臺變頻器。
（2）可根據(jù)一天內(nèi)不同階段的冷量要求，設(shè)置不同要求運行。
（3）常用與備用可切換。
（4）變頻控制與原控制間可換，確保設(shè)備正常運行。3.3 控制系統(tǒng)的主電路圖
3.4 冷凍泵、冷卻泵PLC的控制系統(tǒng)圖
PLC軟件采用梯形圖語言，實現(xiàn)各種邏輯控制、變頻器啟動控制及手動/自動，工頻/變頻轉(zhuǎn)換和故障自動切換等功能。
