What kinds of components are part of computer room air conditioning room air conditioning has what effect? When it comes to computer room air conditioning, we all know that it is main service object of the computer. Computer room air conditioning of the first big role is to provide stable and reliable IDC room and testing room temperature etc. So, room air conditioning is composed of what parts, equipment room air conditioning has what effect? A, room air conditioner consists of which part 1, control monitoring system control system through the controller show that the temperature and the humidity of the air, the working state of the air conditioning unit, analyze each sensor feedback signal, work instructions for each function unit, achieve the goal of controlling air temperature, humidity. 2, the ventilation system various functions within the unit ( Refrigeration, dehumidification, heating, humidification, etc. ) To deal with air in the room, the air flow are needed to complete the exchange of heat and wet, still need to maintain a certain velocity, gas inside the room to prevent dust deposition, and will be suspended in the air dust filter to remove in time. 3, refrigeration cycle and dehumidification system using evaporation compression refrigeration cycle system, it is the use of refrigerant evaporation absorbs the latent heat of vaporization to refrigeration and air-conditioning refrigeration system of refrigerant is to implement the working medium of refrigeration cycle, the critical temperature rise as the increase of pressure, the use of this characteristic, the refrigerant gas compressor is used as the first work compressed into high temperature and high pressure gas, and then sent to the condenser, cooling under high pressure, the gas will be under the high temperature heat condensed liquid, high pressure refrigerant liquid through a throttling device, the pressure drops rapidly after arrived in evaporator boiling under low pressure and temperature within. Constitute the basic refrigeration system mainly has four parts, compressor, evaporator, condenser, expansion valve. Dehumidification system generally use of its own refrigeration cycle system, adopt under the condition of same refrigerating capacity decreases. 4, humidification system through electrode humidifying cans or infrared humidifying equipment such as the tubes, by way of heating water to form water vapor. 5, heating system to heat as a heat compensation, mostly in the form of electric heat pipe. 6, water chilling unit water ( Ethylene glycol) Condenser unit in internal circulation water cooling unit, circulating water through the heat exchanger, the refrigerant vapour condenses into liquid cooling, due to the heat capacity of the water is very big, so the condensing heat exchanger is small, can be adjusted according to the different backwater temperature pressure control the 3-way valve (pos. No. ( Or electric control valve controlling water through the heat exchanger to control the condensing pressure. Circulating water power is supplied by the pump and the heated water, there are several kinds of cooling mode is more commonly used is a cool, dry and cold the water to the airtight dry coil and cooling by fan back, work stability, high reliability, dry and cold but need to have - - - - - - A large volume of cooling coils and fan. Another is open, the cooling system of the water to the cooling water tower spray 'by return after evaporation cooling water itself, this way is always make up water for the system, and asked to soften water, dust and other debris from the air will enter the system, serious blocking pipe, influence heat transfer effect, so still need regular decontamination. Second, what role does the computer room air conditioning in the computer room equipment consists of a large number of microelectronics, precision machinery and equipment, etc, and these devices use a lot of the influence of temperature and humidity of electronic components, mechanical components and materials. The temperature of electronic components, computer room equipment insulation materials and recording medium has a great influence; As for semiconductor components, room temperature increase 10 ℃ within the prescribed scope, its reliability will be reduced about 25%; For capacitor, the temperature increase 10 ℃, the use of time will decline by 50%; Insulation material is also sensitive to temperature, temperature is too high, the structure of the printed circuit board strength will be weakened, the temperature is too low, insulation materials will become fragile, also can make the structure intensity is weak; For recording medium, the temperature is too high or too low will lead to loss of data or access failure. The influence of humidity on computer equipment are also obvious, when relative humidity is higher, the water vapor in the electronic components or form a water film dielectric material, easy to cause formation pathways between electronic components; When the relative humidity is low; Easy to produce high electrostatic voltage test showed that in the computer room, such as relative humidity is 30%, electrostatic voltage is 5000 v, relative humidity is 20%, electrostatic voltage is 10000 v, the relative humidity is 5%, electrostatic voltage is 20000 v, and as high as tens of thousands of volts electrostatic voltage impact on computer equipment is obvious. Computer room precision air conditioning is a special design for modern electronic equipment room air conditioner, its working accuracy and reliability are much higher than common air conditioning. To improve the stability and reliability of the machine room equipment use, the environment must be strictly controlled in certain range of temperature humidity. Computer room precision air conditioning room temperature and relative humidity can be controlled in the plus or minus one degree Celsius, thus greatly improving the life and reliability of the equipment. Room air conditioning as the name suggests is actually a kind of high meant for use by computer room precision air conditioning, why say so, because it is for the control precision of temperature and humidity is very high, so the room air conditioning is very important for computer room construction.
