进行了某市5幢典型高层办公楼的水耗调查和超压出流测试分析,总结了超压出流原因。调查结果表明,绝大多数办公楼的纯办公人员用水单耗超出国家定额;在所有41个测点中,水压超过0.45 MPa的测点有10个,达到24.4%;快开水龙头在半开状态下超压出流率达67%,而在全开状态下超压出流率高达98%;单把陶瓷水龙头(节水水龙头)在测试中的超压出流率为20%。
The water consumption investigation and overpressure outflow test and analysis of five typical high-rise office buildings in a certain city were carried out. The causes of overpressure outflow were summarized. Survey results show that the vast majority of office workers in the water consumption of pure office workers exceeds the national quota; in all 41 test points, the water pressure exceeds 0.45 MPa of the measuring points 10, reaching 24.4%; quick-opening faucet half-open Overpressure outflow rate reached 67% while the overpressure outflow rate was as high as 98% under the full open condition; the overpressure outflow rate of single ceramic faucet (water saving tap) during the test was 20%.
