廣電行業(yè)發(fā)展中機房環(huán)境基礎(chǔ)建設(shè)探討

Discussion on environmental infrastructure room in BCTV development

一叙棚、機房環(huán)境（機房專用空調(diào)解決方案）建設(shè)所面臨的問題莱预。

The problem facing the construction for computer room environment (the solution for computer room).

目前宛徊，很多廣電機房沒有使用機房專用空調(diào)（常被稱為精密空調(diào)，恒溫恒濕機）描扯，而是廣泛應(yīng)用普通舒適性空調(diào)。與機房專用空調(diào)比較，舒適性空調(diào)問題如下：

At present, many broadcasting room does not use the special air conditioning (often called precision air conditioning, constant temperature and humidity air conditioning), but is widely used the ordinary comfort air conditioning. Compared with the room air-conditioning, comfort air conditioning problems is listed as follows:

1） 舒適性空調(diào)出風(fēng)溫度過低耿愈，會導(dǎo)致在出風(fēng)口附近空氣中的水蒸汽飽和凝結(jié)出水滴，對附近的用電設(shè)備造成很大危險倔剩。 

The outlet air temperature for comfort air conditioning is too low, and it results in a steam outlet in the vicinity of the air saturated condensation water droplets and in the vicinity of the electrical equipment caused great danger.

2） 舒適性空調(diào)風(fēng)量過小朦暖，不適合計算機設(shè)備的高熱密度的發(fā)熱特點，無法驅(qū)除機房的“熱島效應(yīng)”盖呼。

The air volume for comfort air conditioning is too small, and is not suitable for the heating characteristics of high density of computer equipment. Heat island effect cannot remove in the room.

3） 舒適性空調(diào)溫度調(diào)節(jié)精度過低儒鹿，溫度調(diào)節(jié)精度為±3～5℃化撕，溫度的波動對設(shè)備穩(wěn)定運行極其不利。

The comfort air conditioning temperature control accuracy is low, and the temperature control precision is ± 3 ~ 5 ℃. A temperature fluctuation is extremely disadvantageous to the stable operation of the equipment.

4） 舒適性空調(diào)沒有濕度控制功能约炎。舒適性空調(diào)無法進行濕度控制植阴。沒有加濕功能，只能進行除濕圾浅，在冬季甚至過度除濕墙贱，濕度過低產(chǎn)生的靜電極易產(chǎn)生設(shè)備故障。

The comfort air conditioning does not have the humidity control function. Comfort air conditioning is not equipped with the humidity control. Not only for dehumidification, humidification function, even in winter over dehumidification, the low temperature generated electrostatic easily that produces equipment failure.

5） 舒適性空調(diào)過濾能力無法達到機房標準贱傀。舒適性空調(diào)只具備簡單的過濾功能惨撇，其過濾器的過濾效果根本無法達到機房的要求。機房專用空調(diào)嚴格按照0.5 微米/升<18,000(B級)設(shè)計府寒，配合以每小時30次的風(fēng)量循環(huán)魁衙，保障機房潔凈。

The comfort air conditioning filter cannot meet the standard for the room. For comfort air conditioning with filtering function, filtering effect of the filter cannot achieve requirements in the room. Computer room air-conditioning is in strict accordance with the 0.5 micron / L <18000 (B) design with 30 times per hour air circulation to ensure the cleanness for security room.

6） 舒適性空調(diào)在北方地區(qū)無法實現(xiàn)低溫（室外）運行株搔。一般標稱-5℃以下即無法制冷和加熱剖淀，而機房是發(fā)熱量很大的區(qū)域，即使在冬天也需要對設(shè)備進行降溫肌辑。

The comfort air conditioning cannot realize the low temperature (outdoor) operation in the northern region. Average nominal -5 ℃ cannot refrigeration and heating, but the room is the regional heating of large quantity, even in the winter the need for equipment cooling.

7） 舒適性空調(diào)維護量大足渔，舒適性空調(diào)長期應(yīng)用在非設(shè)計工況下，故障率高刹造，能效比不斷下降丹碑，越來越耗能。機房專用空調(diào)按照全年長期運行設(shè)計劫欣，維護量小候隘。

The comfort air conditioning maintenance is large. For long-term application at off design conditions the failure rate is high, and the energy efficiency ratio is decreased to cause more and more energy consumption. Room air-conditioning is designed for annual long-term operation, and has small amount of maintenance.

8） 舒適性空調(diào)在機房內(nèi)應(yīng)用，壽命短盹清。在365天/24小時應(yīng)用的情況下其壽命一般不超過3年（機房專用空調(diào)的設(shè)計壽命一般為連續(xù)運轉(zhuǎn)10年）裆乘。

Application of comfort air conditioning in the room has short service life. In the hour of 365 days 24 hours application, the case of life is generally less than 3 years (the design life of special air conditioning in the room generally runs continuously for 10 years).

9） 舒適性空調(diào)耗電量大，機房專用空調(diào)選用的工業(yè)等級壓縮機能效比高達3.3曾辙。而舒適性空調(diào)目前業(yè)界選用的高等級壓縮機能效比約2.9衅逝，同時考慮到其他設(shè)計差異,如顯熱比指標，舒適性空調(diào)比同容量的機房專用空調(diào)多耗電20%-30%,不僅增加使用成本糕米，也浪費能源忠伊。

The comfort air conditioning has large power consumption. Computer room air-conditioning uses industrial grade compressor, and the energy efficiency ratio is up to 3.3. High grade compressor energy efficiency ratio for the comfort air conditioning is at present with 2.9, while the other takes into account the design differences, such as the sensible heat ratio index, comfort air conditioning compared with the same volume of computer room air conditioner increases the power consumption of 20%-30%, not only increases the cost, but also a waste of energy.

以上舒適性空調(diào)的問題，將影響機房設(shè)備的安全運行钾埂，增加機房運行成本河闰，需要應(yīng)用機房專用空調(diào)予以解決科平。

The problems for comfort air conditioning showing above will affect the safe operation of equipment, and increase the operation cost. Thus, it needs special air conditioner to solve.
