- 机房环境（机房专用空调解决方案）建设所面临的问题。
The problem facing the construction for computer room environment (the solution for computer room).
目前，很多广电机房没有使用机房专用空调（常被称为精密空调，恒温恒湿机），而是广泛应用普通舒适性空调。与机房专用空调比较，舒适性空调问题如下：
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:
目前，很多广电机房没有使用机房专用空调（常被称为精密空调，恒温恒湿机），而是广泛应用普通舒适性空调。与机房专用空调比较，舒适性空调问题如下：
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:
- 舒适性空调出风温度过低，会导致在出风口附近空气中的水蒸汽饱和凝结出水滴，对附近的用电设备造成很大危险。
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.
- 舒适性空调风量过小，不适合计算机设备的高热密度的发热特点，无法驱除机房的“热岛效应”。
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.
- 舒适性空调温度调节精度过低，温度调节精度为±3～5℃，温度的波动对设备稳定运行极其不利。
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.
- 舒适性空调没有湿度控制功能。舒适性空调无法进行湿度控制。没有加湿功能，只能进行除湿，在冬季甚至过度除湿，湿度过低产生的静电极易产生设备故障。
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.
- 舒适性空调过滤能力无法达到机房标准。舒适性空调只具备简单的过滤功能，其过滤器的过滤效果根本无法达到机房的要求。机房专用空调严格按照0.5 微米/升<18,000(B级)设计，配合以每小时30次的风量循环，保障机房洁净。
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.
- 舒适性空调在北方地区无法实现低温（室外）运行。一般标称-5℃以下即无法制冷和加热，而机房是发热量很大的区域，即使在冬天也需要对设备进行降温。
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.
- 舒适性空调维护量大，舒适性空调长期应用在非设计工况下，故障率高，能效比不断下降，越来越耗能。机房专用空调按照全年长期运行设计，维护量小。
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.
- 舒适性空调在机房内应用，寿命短。在365天/24小时应用的情况下其寿命一般不超过3年（机房专用空调的设计寿命一般为连续运转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).
- 舒适性空调耗电量大，机房专用空调选用的工业等级压缩机能效比高达3.3。而舒适性空调目前业界选用的高等级压缩机能效比约2.9，同时考虑到其他设计差异,如显热比指标，舒适性空调比同容量的机房专用空调多耗电20%-30%,不仅增加使用成本，也浪费能源。
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.
以上舒适性空调的问题，将影响机房设备的安全运行，增加机房运行成本，需要应用机房专用空调予以解决。
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、机房环境（机房专用空调解决方案）建设推荐案例 (Computer room environment (the solution for special air conditioning) recommended case)
某广电IDC中心机房，建筑面积705.6平方米，层高 4.3米，按照功能的要求分为A区、B区、C区及D区，第一消防分区为A区，第二消防分区为B区、C区及D区。如下图：
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:
考虑建筑热负荷及设备（计算机等）热负荷, A区所需冷量不小于210KW, B区、C区及D区所需冷量不小于190KW。在这个方案中，如果考虑应用舒适空调，以5P为例，即使不考虑备份，也需要32套，应用中无法达到IDC机房需要的温湿度、洁净度标准。同样中央空调也无法实现这个IDC机房的空气调节要求。合理的机房专用空调应用及设计方案，才能满足机房环境建设的合理性、安全性、可扩容性。此IDC机房空调方案分析如下：
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:
