冷水遠(yuǎn)傳壓力表7和熱水遠(yuǎn)傳壓力表，分別檢測(cè)自來(lái)水端和燃?xì)忮仩t熱水端的水壓，并把檢測(cè)到的信號(hào)轉(zhuǎn)變成電信號(hào)送到控制器，在控制器內(nèi)通過(guò)比較這兩路信號(hào)高低，產(chǎn)生一個(gè)壓差信號(hào)輸出到變頻器，變頻器控制增壓泵的運(yùn)行速度，使熱水壓力隨時(shí)跟蹤自來(lái)水壓力，使兩者一直保持平衡。另外，當(dāng)房間的熱水長(zhǎng)時(shí)間不用時(shí)，管道內(nèi)的水溫必然降低，為此在熱水系統(tǒng)中加裝了一個(gè)循環(huán)泵，使熱水一直保持循環(huán)狀態(tài)，這樣無(wú)論何時(shí)都可以實(shí)現(xiàn)恒溫供熱水。
