澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票酒店内的游泳池为娱乐性泳池,其空调通风系统通常有两种做法:采用组合式空调箱,利用空调系统的冷热源;采用泳池专用除湿热泵系统。(一般是三合一机组,回收热量给泳池加热,有风冷散热的,没有条件装风冷冷凝器的也有采用冷冻水散热的。

The swimming pool in the hotel is an entertainment swimming pool, and its air conditioning and ventilation system usually has two methods: using combined air conditioning box and using the cold and heat sources of the central air conditioning system; Special dehumidification heat pump system for swimming pool is adopted. (generally, it is a three in one unit, which recovers heat to heat the swimming pool. There are air-cooled units for heat dissipation, and there are those that are not equipped with air-cooled condensers or chilled water units for heat dissipation.

1种方案的初投资比较低。

The initial investment of one scheme is relatively low.

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票2种方案具有热回收功能,回收排风中的能量,冷凝热还可用于池水的加热,运行比较节能,但是初投资比较高。设方案的选择应综合考虑初投资与运行费用。

The two schemes have the function of heat recovery to recover the energy in the exhaust air. The condensation heat can also be used for the heating of pool water. The operation is relatively energy-saving, but the initial investment is relatively high. The initial investment and operation cost should be comprehensively considered in the selection of schemes in the design.

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票直缝管所受的主应力恰恰垂直于管材抗冲击才能 低的方向,而螺旋钢管则错开了管材抗冲击才能 低的方向,使螺旋钢管焊缝长的优势改变成上风。螺旋钢管的防腐办法也从抑止其中某一进程。在运用进程中,螺旋钢管的主应力方向,即钢管轴线方向确当量缺陷长度比直缝管小;其次,由于管线钢均为轧制钢板,冲击韧性有较大的各向同性,顺轧制方向的CVN值可比垂直于轧制方向的CVN值高3倍。运用钢丝刷等工具对钢材外表中止打磨,能够去除松动或翘起的氧化皮、铁锈、焊渣等。

The principal stress of the straight seam pipe is just perpendicular to the direction of the low impact resistance of the pipe, while the spiral steel pipe staggers the direction of the low impact resistance of the pipe, changing the advantage of the weld length of the spiral steel pipe into the upper wind. The anti-corrosion method of the spiral steel pipe also suppresses one of the processes. In the application process, the principal stress direction of the spiral steel pipe, that is, the direction of the steel pipe axis, is the same as the defect length Secondly, because the pipeline steel is rolled steel plate, the impact toughness has greater isotropy, and the CVN value along the rolling direction can be three times higher than that perpendicular to the rolling direction. The use of wire brush and other tools to stop grinding the steel surface can remove loose or warped oxide scale, rust, welding slag, etc.

当通风系统的总量和压力损失较大时,可将其分为小系统。气流在管道内的流速不宜过高,以免引起再生噪声。确定管道内气流流速应根据不同要求按有关规定选取。节能通风有很多种定义而且实现的方法,其中主要的定义在于满足各种通风条件的前提之下。使用低廉低碳的通风设备来控制空气中的污染和危害的传播,这是借助换气的方法来稀释各种有害物质和空气中的细菌的通风排出方法。

When the total amount and pressure loss of the ventilation system are large, it can be divided into small systems. The flow velocity in the pipeline should not be too high to avoid regenerative noise. The determination of the flow velocity in the pipeline should be selected according to different requirements and relevant regulations. There are many definitions and Implementation methods of energy-saving ventilation, of which the main definition is on the premise of meeting various ventilation conditions Low cost and low-carbon ventilation equipment to control the spread of pollution and harm in the air, which is a ventilation method to dilute various harmful substances and bacteria in the air by means of ventilation.
