Cleveland’s newest Holiday Inn may look like a typical hotel from the outside, but its location, purpose, and special features make it one of a kind. The hotel is built adjacent to the world renowned Cleveland Clinic and is designed to serve the many people who visit or serve the sprawling clinic campus. Looking inside the hotel, visitors will find another unique feature: a mechanical room equipped with 29 wall-mounted A. O. Smith ATI 540H-N fully modulating condensing tankless water heaters.
“We’ve done a number of tankless installations in Ohio, but never anything of this scope,” Kevin Conyngham of LIBB Company, Inc., the manufacturer’s representative responsible for coordinating the project, observed.
Conyngham解释说，在5月份开放的酒店业主希望使用无水加热器，因为克利夫兰诊所对能源效率和可持续性的兴趣。199万BTU A. O.史密斯单位提供了0.95的能量因子，共同努力，为酒店客人和工作人员提供足够的热水。
与许多酒店不同，新假日酒店临近的诊所不会经历相同类型的6:00至8:00。早上“高峰时间”在此期间，客人要求淋浴或沐浴的大量热水。附近的诊所，访问医师和家庭成员的供应商将弥补大部分酒店的客人 - 他们往往在白天或黑夜的所有时间到达和离开。尽管如此，A. O.史密斯单位已准备好全天满足他们的热水需求。
29个单位分为两个区域,吉姆罗迪Jr., president of Northern Ohio Plumbing Co., Inc., the mechanical contractor who installed the water heaters, explained. Eleven units supply 140-degree hot water to the laundry and kitchen, while 18 units serve the 284 guest rooms with 110-degree hot water. Not surprisingly, the laundry requires the most hot water, although the Moce Café and Bar and the hotel’s event facilities also demand ample quantities of hot water. The A. O. Smith tankless water heaters’ modulating capability means the units will be able to ramp up to meet peak demands while, at the same time, saving energy and cost for the owner group.
NOP团队确定了许多节省空间和安装期间成本降低的许多创造性方法。原始规范要求在机械室内安装在预制造的机架系统上的无罐单元。NOP的Ben Welton公司而不是使用机架系统方法，而是拥有独特的壁挂安装，可挽救机械房间空间。他交错了这些单位充分利用了可用的墙壁;交错的方法也更好地容纳热水器的管道和通风。
“完成的工作就像原版一样，”Conyngham指出。
NOP also maximized the venting capabilities of the tankless units. The contractor installed one large plenum that branched into individual air intake pipes to supply the 29 water heaters with fresh air. This approach required creating just one hole in the mechanical room’s exterior wall. The units’ exhaust vents are collected into a set of four large exhaust vents that exit the building through one wall. PVC water lines from each of the tankless water heaters lead to a series of risers; one pair of risers serves each guest floor.
The modulating capability of the A. O. Smith condensing tankless water heaters eliminated the need for the hot water storage tank normally found in a hotel application. NOP tested the system, running multiple showers on multiple floors at the same time, Roddy pointed out. The water heaters were able to keep up with the demand.
A. O. Smith 199,000 BTU储烟单元被评定为每分钟提供10加仑热水的最大流速。即使在克利夫兰的寒冷冬天的死亡中，水加热器也可以每分钟提供至少四加仑的热水或七加仑混合水，Conyngham指出。
热水器本身和机械房的布局承诺使维护扣。
“很好的部分是系统的冗余。如果一个单元需要维护，您就不必关闭系统，并且酒店仍将有热水，“威尔顿指出。
