If the temperature of external environment is lower and air quality when relatively good, system will directly adopt the intelligent fresh air technology to carry out inside and outside heat exchange; If the temperature of external environment is lower and the mass ratio of air when abominable, system will adopt heat-exchange system to carry out the heat exchange of indoor and outdoor; When the temperature of external environment when higher, system will independently switch to the state of compressor cooling, in the process of the autonomous refrigeration of compressor, if evaporator temperature sensor detects the evaporator surface frosting, system can be out of service so, does the processing of defrost.
For electronic devices and components in the rack, if humidity is too big, when being lowered the temperature, rack forms condensed water, the serious consequence of can form short circuit like this, burning electronic devices and components easily.If humidity is too low, will form static, also can form the operation of electronic devices and components and disturb.So with humidity sensor the humidity in the rack is detected, when humidity surpasses our preset value, the temperature control balance sysmte will be to carrying out dehumidification treatments in the rack, when if humidity is too low, the temperature control balance sysmte will be to adding wet process in the rack, to guarantee that humidity in the rack is within a reasonable range.
If the temperature of external environment is higher than the temperature in the rack, compressor refrigeration system will start so, compressor is the power of compressor assembly when running refrigerating, cold-producing medium enters in the condenser become the gas of HTHP through the compression of compressor after, heat release becomes the liquid refrigerant of high pressure low temperature in condenser, after becoming the low-pressure low-temperature state after the throttling arrangement throttling, enter in the evaporator, refrigeration machine absorbs heat and becomes gaseous medium and absorbed to finish the circulation of compressor cooling by compressor again in evaporator, so repeatedly.Condenser and evaporator to strengthen cross-ventilation, are strengthened the heat exchange effect by separately circulating fan.Wherein the heat exchange of condenser and air is carried out outside rack, and the heat exchange of evaporator and air then circulates in airtight cabinet and carries out.
If the temperature of external environment is lower than the temperature in the rack and the mass ratio of external environment air preferably the time, the natural fresh air system will start so.The natural fresh air system is from physical angle, the unbalanced air that causes of positive exactly negative pressure flows, according to sending new wind with special equipment to indoor in an airtight indoor side, again from opposite side by special equipment to outdoor discharge, then can form " new wind flow field " indoor, make an airtight space realize the cross-ventilation of science.The temperature control balance sysmte is by after temperature sensor, the outer temperature sensor of cabinet, air quality transducer image data comprehensively contrast in the rack, if the air quality outside the cabinet is higher, controller will be opened the inside and outside air door of separating of rack, be come to lowering the temperature in the rack by VMC.On the contrary, then adopt other form to lower the temperature to machine room, thereby satisfy the needs of indoor fresh-air ventilation.After the operation of natural fresh air system, motor start-up is opened air door, outer blower fan sucks outdoor cold air, cold wind is distinguished and admirable through behind the air door, be drained into indoorly under the dynamic action of inner blower, and the hot blast in the rack is absorbed through air door by inner blower, is discharged into external environment to have suffered, cold air enter eliminating with hot-air, reduce indoor temperature with this.
If the temperature of external environment is lower than the temperature in the rack, when but the mass ratio of external environment air is relatively poor, if also adopt the intelligent fresh air system, air strainer before the VMC will be easy to stop up so, if often do not safeguard that VMC will lose effect, and often safeguard, maintenance cost is higher, so start heat-exchange system this moment.In the intelligent fresh air system, because the physical effect of medium, when temperature is hanged down cabinet outside, the medium condensation liquefy of will dispelling the heat, effect by gravity flow into the kinetic pump porch, by kinetic pump liquid medium is delivered to evaporation channel in the rack again, because the temperature in the rack is higher, satisfy the evaporating temperature of medium fully, so medium will absorb the heat in the rack, medium absorbs and enters condensation channel again after heat becomes gas, carries out repeatedly according to this, reaches the cooling-down effect in the rack.Condenser and evaporator to strengthen cross-ventilation, are strengthened the heat exchange effect by separately circulating fan.Wherein the heat exchange of condenser and air is carried out outside control cubicle, and the heat exchange of evaporator and air then circulates in airtight control rack and carries out.In sum, after heat-exchange system starts operation, kinetic pump produces motive force, making efficiently, cold-producing medium enters in the condenser of concurrent flow, because ambient temperature is low, this medium can immediately form liquid form, then in the evaporator in the inlet chamber, because the indoor temperature height, this medium absorbs heat at once and becomes gaseous material and suck to finish a kind of refrigeration cycle by kinetic pump again.
Inner blower sucks hot gas in rack, distinguished and admirable through becoming cold gas discharge after the fin of evaporator, to reach the effect of lowering the temperature in the rack; Inner blower sucks the gas the environment outside cabinet, distinguished and admirable through becoming the gas discharge of heat behind the condenser fin.So just form heat from indoor to outdoor transfer.
When the temperature outside the cabinet was higher than temperature in the rack, controller will cut out kinetic pump, and the passage of medium will block from kinetic pump, avoided medium thus because the outer temperature of cabinet is higher than in the rack temperature and dispels the heat in rack.
Alarm module in the controller has the interior high temperature alarm of rack, evaporator to freeze multinomial warning functions such as warning, system low-voltage, alarm for high voltage, over-voltage and over-current warning.After warning takes place, controller can send to the warning error sign indicating number in attendant's the communication apparatus by GPRS, allow the attendant obtain the operation conditions of new wind, heat exchange, heating, refrigeration intelligent temperature control system timely, make to safeguard in time, can generation systems do not break down and attendant's ignorant this situation for a long time.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection range of the present utility model with this; every according to the technological thought that the utility model proposes, as to do on the technical scheme basis any change all falls within the protection range of the present utility model.
