酒店內(nèi)的游泳池為娛樂性泳池，其空調(diào)通風(fēng)系統(tǒng)通常有兩種做法：采用組合式空調(diào)箱，利用空調(diào)系統(tǒng)的冷熱源；采用泳池專用熱泵系統(tǒng)。（一般是三合一機(jī)組，回收熱量給泳池加熱，有風(fēng)冷散熱的，沒有條件裝風(fēng)冷冷凝器的也有采用冷凍水散熱的。

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種方案的初投資比較低。

The initial investment of one scheme is relatively low.

2種方案具有熱回收功能，回收排風(fēng)中的能量，冷凝熱還可用于池水的加熱，運(yùn)行比較，但是初投資比較高。設(shè)方案的選擇應(yīng)綜合考慮初投資與運(yùn)行費(fèi)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.

直縫管所受的主應(yīng)力恰恰垂直于管材抗沖擊才能 低的方向，而螺旋鋼管則錯(cuò)開了管材抗沖擊才能 低的方向，使螺旋鋼管焊縫長的優(yōu)勢改變成上風(fēng)。螺旋鋼管的防腐辦法也從抑止其中某一進(jìn)程。在運(yùn)用進(jìn)程中，螺旋鋼管的主應(yīng)力方向，即鋼管軸線方向確當(dāng)量缺陷長度比直縫管小;其次，由于管線鋼均為軋制鋼板，沖擊韌性有較大的各向同性，順軋制方向的CVN值可比垂直于軋制方向的CVN值高3倍。運(yùn)用鋼絲刷等工具對鋼材外表中止打磨，能夠去除松動(dòng)或翹起的氧化皮、鐵銹、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.

當(dāng)通風(fēng)系統(tǒng)的總量和壓力損失較大時(shí)，可將其分為小系統(tǒng)。氣流在管道內(nèi)的流速不宜過高，以免引起再生噪聲。確定管道內(nèi)氣流流速應(yīng)根據(jù)不同要求按有關(guān)規(guī)定選取。通風(fēng)有很多種定義而且實(shí)現(xiàn)的方法，其中主要的定義在于滿足各種通風(fēng)條件的前提之下。使用低廉低碳的通風(fēng)設(shè)備來控制空氣中的污染和危害的傳播，這是借助換氣的方法來稀釋各種有害物質(zhì)和空氣中的細(xì)菌的通風(fēng)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.
