常見例句Because very little hot water is required to maintain the low temperature in the mains (usually 140oF), a relatively small capacity recirculator can generally be specified. 由於衹需要很少的熱水來維持主琯道的低溫度(通常爲(wèi)60oC),通??赡苄枰付ㄒ粋€(gè)相對(duì)較小功率的循環(huán)器。NOTE: Recirculating control aquastat must be set at least 5oF to 10oF lower than the temperature setting of the Series N170-M2 valve, otherwise the recirculator will run continually. 注:再循環(huán)控制水溫自動(dòng)調(diào)節(jié)器的溫度設(shè)置必須比系列N170-M2閥門的設(shè)置溫度低5至10華氏度,否則,再循環(huán)器將會(huì)不斷運(yùn)行。water recirculator 水再循環(huán)器 返回 recirculator
