  • 機房環境(機房專用空調解決方案)建設所面臨的問題。
The problem facing the construction for computer room environment (the solution for computer room).
目前,很多廣電機房沒有使用機房專用空調(常被稱為精密空調,恒溫恒濕機),而是廣泛應用普通舒适性空調。與機房專用空調比較,舒适性空調問題如下:
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. 舒适性空調出風溫度過低,會導緻在出風口附近空氣中的水蒸汽飽和凝結出水滴,對附近的用電設備造成很大危險。 
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.
  1. 舒适性空調風量過小,不适合計算機設備的高熱密度的發熱特點,無法驅除機房的“熱島效應”。
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.
  1. 舒适性空調溫度調節精度過低,溫度調節精度為±3~5℃,溫度的波動對設備穩定運行極其不利。
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.
  1. 舒适性空調沒有濕度控制功能。舒适性空調無法進行濕度控制。沒有加濕功能,隻能進行除濕,在冬季甚至過度除濕,濕度過低産生的靜電極易産生設備故障。
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.
  1. 舒适性空調過濾能力無法達到機房标準。舒适性空調隻具備簡單的過濾功能,其過濾器的過濾效果根本無法達到機房的要求。機房專用空調嚴格按照0.5 微米/升<18,000(B級)設計,配合以每小時30次的風量循環,保障機房潔淨。
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.
  1. 舒适性空調在北方地區無法實現低溫(室外)運行。一般标稱-5℃以下即無法制冷和加熱,而機房是發熱量很大的區域,即使在冬天也需要對設備進行降溫。
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.
  1. 舒适性空調維護量大,舒适性空調長期應用在非設計工況下,故障率高,能效比不斷下降,越來越耗能。機房專用空調按照全年長期運行設計,維護量小。
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.
  1. 舒适性空調在機房内應用,壽命短。在365天/24小時應用的情況下其壽命一般不超過3年(機房專用空調的設計壽命一般為連續運轉10年)。
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).
  1. 舒适性空調耗電量大,機房專用空調選用的工業等級壓縮機能效比高達3.3。而舒适性空調目前業界選用的高等級壓縮機能效比約2.9,同時考慮到其他設計差異,如顯熱比指标,舒适性空調比同容量的機房專用空調多耗電20%-30%,不僅增加使用成本,也浪費能源。
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.
以上舒适性空調的問題,将影響機房設備的安全運行,增加機房運行成本,需要應用機房專用空調予以解決。
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.

四、機房環境(機房專用空調解決方案)建設推薦案例 (Computer room environment (the solution for special air conditioning) recommended case) 
某廣電IDC中心機房,建築面積705.6平方米,層高 4.3米,按照功能的要求分為A區、B區、C區及D區,第一消防分區為A區,第二消防分區為B區、C區及D區。如下圖:
A radio IDC center, a building area of 705.6 square meters, 4.3 meters tall, according to the functional requirements is divided into A zone, B zone, C zone and D zone. The first fire partition is for A zone. The second fire partition is for B area, C area and D area. The following diagram:

考慮建築熱負荷及設備(計算機等)熱負荷, A區所需冷量不小于210KW, B區、C區及D區所需冷量不小于190KW。在這個方案中,如果考慮應用舒适空調,以5P為例,即使不考慮備份,也需要32套,應用中無法達到IDC機房需要的溫濕度、潔淨度标準。同樣中央空調也無法實現這個IDC機房的空氣調節要求。合理的機房專用空調應用及設計方案,才能滿足機房環境建設的合理性、安全性、可擴容性。此IDC機房空調方案分析如下:
Considering the building heat load and heat load of equipment (computer), A zone required cold quantity that is not less than 210KW, and B, C and D areas required cold quantity that is not less than 190KW. In this scheme, if we consider the application of comfort air conditioning, taking 5HP as an example, even without taking into account the backup, also need 32 sets, the application cannot achieve the requirements of temperature and humidity and IDC room needs of cleanliness standard. The central air-conditioning also cannot achieve the requirements for IDC computer room air conditioning. Reasonable room for air conditioning applications and design will meet the environmental construction which is reasonable, safety, expansibility. Analysis of the IDC computer room air conditioning scheme are as follows:

Zone B, C, and D with 4 units of 65UA (of which 1 standby), single unit refrigerating capacity of 66.6KW, can provide the total cooling capacity of 266.4KW. Above the recommended configuration unit can fully satisfy the cooling load requirements, and achieve 3+1 backup, any fault or maintenance, normal operation of other units, to protect the system security.
