Air-conditioning system
Air-conditioning system of military information center is divided as follow:
1) Precision Air Conditioner, used in computer room, important military data processing and confidential tel-communication room. It is very important to control temperature and humidity precisely so that the equipments can work smoothly.
2) Comfortable air-conditioning and fresh air system, used in monitor room, office area, etc. in order to provide a comfortable working environment.
Phoenix is one of the earliest manufacturers to produce Precision air-conditioner. About 20 years ago, Phoenix developed modularized Precision Air Conditioner and set up the first modularized product line in this field. Phoenix factory on Ireland was the earliest kind to be built based on ISO Standards. It also established a complete system including R&D Center, product line and after-sale service. Strictly comply with the technical standards and filed standards, Phoenix designs and produces all kinds of Precision Air Conditioner used in computer rooms, lab rooms, and special places with high requirements on environment temperature and humidity. Phoenix Precision air-conditioner provides a safe environment for the smooth 24hour running of the equipments in computer room. Based on the confidence to products and extremely responsible attitude to customers, Phoenix set up the free hot-line in the earliest time. The brands name owned by Phoenix Group such as Phoenix and Airwinnow have already represented reliability and high quality.
Phoenix Precision air-conditioners are widely used in many countries and areas in Europe, America and Asia. At present, Phoenix Precision Control air-conditioners provide 24hours safe environment for many good equipments, such as BELL, SIEMENS, NOKIA, MOTOROLA, HP, DELL, NEC, COMPAQ, SUN, EMC, FUJITSU, SG, IBM, etc.
Usually the main computer room of a Military Information Center is no more than 200 m2. We recommend Phoenix modularized Precision Air Conditioner which is specially made for data room, communication room and computer room. The refrigerant capacity of standard modular varies from 10kW to 80kW. The standard modules can be assembled flexibly. It can totally fulfill the high requirements of a movable military information center.
2.Method of calculating refrigerant capacity
a) Estimated calculation of refrigerant capacity for a data room: in a middle size military information center, the size of a data room usually is no more than 150m2. If the heat emitting volume of the equipments and building is not confirmed yet, we may calculate the refrigerant capacity according to general volume 300w～500w/m2, and in some data room with more equipments, it may reach 600 w/m2.
For example, the size of data room is 150 m2, so the refrigerant capacity it needs is 60KW. Choosing one set PDA30/30 with refrigerant capacity 60KW/set，and then its total refrigerant capacity is 65KW which can satisfy the needs. In order to assure the reliability of the equipments, you can add another PDA30 as backup, then 3 modules in total. You may adjust the modules according to the final measuring of the heat emitting volume.
b) The size of confidential tel-communication room is 50m2, so the refrigerant capacity it needs is 30KW. Choosing one set PDA30 with refrigerant capacity 30KW/set，and then its total refrigerant capacity is 32KW which can satisfy the needs. In order to assure the reliability of the equipments, you can add another PDA30 as backup, then 2 modules in total.
