The master chip of controller 12 adopts the microprocessor of 16 low-power consumption, has that detected parameters is many, a fast operation, characteristics that accuracy is high, and energy savings effectively.Be provided with alarm module and GPRS module in controller 12.
The present invention adopts concealed design, and the integrated temperature control balance sysmte is arranged on cabinet walls inside, can greatly increase the IP grade of integrated temperature control balance rack, and very aesthetic property, anti-theft ability is also very strong.
The present invention is built-in temperature sensor, humidity sensor 9, smoke detector 10, air quality transducer 11, pressure switch difference detected temperatures, humidity, smoke condition, air quality and pressure and other parameters, wherein temperature sensor is provided with three, is respectively used to measure temperature, the temperature of cabinet external environment and the temperature of evaporator in rack.The present invention is after the operation that powers on, controller 12 can carry out Comprehensive Correlation facing to the temperature that three temperature sensor collections are come, in the value that adds that air quality transducer 11 gathers, compare with preset value, the integrated temperature control balance sysmte is selected best control program from new wind, heat exchange, heating and four kinds of temperature control system patterns of refrigeration.
If the temperature of external environment is lower and air quality when relatively good, the integrated temperature control balance sysmte 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 more abominable, the integrated temperature control balance sysmte will adopt heat-exchange system to carry out the heat exchange of indoor and outdoor; When the temperature of external environment is higher, the integrated temperature control balance sysmte 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 rack, if humidity is too large, when being lowered the temperature, rack easily forms condensed water, the serious consequence of can form short circuit like this, burning electronic devices and components; If humidity is too low, can form static, also can form the operation of electronic devices and components and disturb.The integrated temperature control balance sysmte detects with the humidity in 9 pairs of racks of humidity sensor, when humidity surpasses our preset value, the integrated temperature control balance sysmte will be to carrying out dehumidification treatments in rack, when if humidity is too low, the integrated temperature control balance sysmte will be to adding wet process in rack, to guarantee that humidity in rack is within a rational scope.
If the temperature of external environment higher than the temperature in rack, will start refrigerating system.Compressor 17 is the power of refrigerating system when running refrigerating, cold-producing medium enters in condenser become the gas of HTHP through the compression of compressor 17 after, heat release becomes the liquid refrigerant of high pressure low temperature in condenser, enter in evaporator after becoming the low-pressure low-temperature state after the throttling arrangement throttling, cold-producing medium absorbs heat and becomes gaseous medium and again absorbed to complete the circulation of compressor cooling by compressor in evaporator, so repeatedly.Condenser and evaporator to strengthen cross-ventilation, are strengthened heat transfer 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 loops in airtight cabinet.
If the temperature of external environment is lower than the temperature in rack and the mass ratio of external environment air preferably the time, will start VMC.VMC is from physical angle, it is exactly the unbalanced Air Flow that causes of positive/negative-pressure, 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, in indoor can formation " new wind flow field ", make an airtight space realize the cross-ventilation of science.The temperature control balance sysmte is by after in rack, temperature sensor, the outer temperature sensor of cabinet, air quality transducer image data are carried out Comprehensive Correlation, if the air quality outside cabinet is higher, controller will be opened the inside and outside demarcation strip of rack, by VMC to lowering the temperature in rack.On the contrary, adopt other form to lower the temperature to machine room, thereby satisfy the needs of indoor fresh air ventilating.After the VMC operation, motor start-up is opened air door, outer blower fan sucks outdoor cold air, cold wind is distinguished and admirable through after air door, be drained into indoorly under the dynamic action of inner blower, and the hot blast in 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 rack, but when the mass ratio of external environment air is relatively poor, if also adopt VMC, air strainer 3 before VMC will be easy to stop up so, if often do not safeguard, VMC will lose effect, and often safeguards, maintenance cost is higher, so should start heat-exchange system this moment.In VMC, due to the physical effect of medium, when temperature is low outside cabinet, the medium condensation liquefy of will dispelling the heat, flow into kinetic pump 1 porch by action of gravitation, by kinetic pump 1, liquid medium is delivered to evaporator in rack again, because the temperature in rack is higher, satisfy the evaporating temperature of medium fully, therefore medium will absorb the heat in rack, the Absorption of Medium heat enters condenser after becoming gas again, repeatedly carries out according to this, reaches the cooling-down effect in rack.Condenser and evaporator to strengthen cross-ventilation, are strengthened heat transfer 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 loops in airtight control rack.In sum, after heat-exchange system starts operation, kinetic pump 1 produces motive force, efficient cold-producing medium is entered in the condenser of concurrent flow, because ambient temperature is low, this medium can immediately form liquid form, then enters in indoor evaporator, because indoor temperature is high, this medium absorbs heat at once and becomes gaseous material and sucked by kinetic pump 1 and complete a kind of refrigeration cycle.
During higher than the temperature in rack, controller 12 will cut out kinetic pump 1 when the temperature outside cabinet, the passage of medium will the driven force pump 1 place block, avoid thus medium because the outer temperature of cabinet is dispelled the heat in rack higher than temperature in rack.
Alarm module in controller 12 has the interior high temperature alarm of rack, evaporator to freeze the multinomial warning functions such as warning, system low-voltage, alarm for high voltage, over-voltage and over-current warning.After warning occurs, controller can send to the warning error code in attendant's communication apparatus by GPRS, allow the attendant obtain timely the operation conditions of new wind, heat exchange, heating, refrigeration intelligent temperature control system, make and safeguard in time, can generation systems do not break down and attendant's ignorant this situation for a long time.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis is within all falling into protection scope of the present invention.
