Abstract

The invention aims at solving the problem that in order to maintain the normal working temperature of equipment, temperature-adjusting air conditioners need to be arranged in various unattended equipment rooms or mobile communication stations with the electric equipment thereof automatically running the entire year. An operation mode of the air conditioners that heat is transferred by secondary heat exchange by using a sealed system is adopted in existing equipment rooms or stations, and the energy consumption of the air conditioners reaches an upper limit. The invention discloses a second method for saving the power of the temperature-adjusting air conditioners in the unattended equipment rooms (or stations), which changes the sealed system into an open system, changes a simple temperature control method with the air conditioners into a temperature control method that utilizes ventilation in the single hot and cool airflow direction for directly discharging heat out of the room and combines effective interface temperature reduction with the temperature control of the air conditioners by adding an air guide sleeve and a guide pipe in the room as well as carrying out measures such as semiconductor-typed improvement that is favorable for outward radiating and goes against inward heat feeding to the surrounding interfaces of the original equipment rooms or stations, and the second method also adopts a method which combines natural air exhaust with electric air exhaust for ventilation, thus saving the power consumption of the temperature-adjusting air conditioners in the equipment rooms or stations by about 70 percent.

Description

The power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning improves

(1) background technology:

In interior various unattended equipment rooms or the dotted mobile communication base station that has electric equipment to move automatically throughout the year, because electric equipment can constantly produce heat when operation, if can not in time dispel the heat, will cause indoor environment temperature to raise, make electric equipment be difficult to continue normal operation.In order to keep the normal working temperature of equipment, the heat that produces in the time of just must working equipment is dispersed into outdoor going.Because operation is unattended automatically, these machine rooms or base station all are in air-tight state naturally.Airtight purpose not only enters for fear of the idler, prevents to hinder and damage or steal, also for dustproof.In order to satisfy the needs of equipment cooling in airtight machine room or the base station, people can utilize air conditioner to carry out temperature control (actual just cooling) naturally.The whole world is not always the case, and be accustomed to be considered as inevitable.

In principle, the temperature control air-conditioning method of existing machine room or base station, actual is the heat that produces when by the secondary transducing indoor electric appliance equipment work in enclosed system and because indoor and outdoor exchange heat and unnecessary transfer of heat in the inlet chamber arrives outdoor.So-called " enclosed system ", referring to this class machine room or base station all is to be in door and window to close the unmanned air-tight state of work automatically usually.So-called secondary transducing, the indoor set that refers at first by air conditioner is transferred to refrigerant (transducing) to indoor unnecessary heat transmission, be transferred to outdoor air by the heat transmission that refrigerant is entrained of the off-premises station of air conditioner again, dispel the heat in outdoor (secondary transducing).In such working method, not only the caloric requirement that produces of the indoor set of indoor electric appliance equipment and air conditioner when work just can be transferred to outdoorly through the secondary transducing, at the interface imports secondary transducing that indoor heat also must pass through air conditioner because of ambient temperature is higher from door and window wall top cover etc. in summer and just can transfer to outdoor.Air conditioner not only causes exceeding the net quantity of heat of regulation operating temperature out and out in the transfer chamber, but also power consumption is increased greatly because of the efficiency of secondary transducing.Even in environment temperature lower season, the heat that main equipment produced often still has considerable caloric requirement just can pass through the secondary transducing by air conditioner except that passing the part by interfaces such as door and window wall top covers.Therefore, the air conditioner working method of existing " enclosed system secondary transducing " is actual is the upper limit that is operated in the power consumption of temperature control air-conditioning.Because this class machine room or base station all are the state of working constantly all the year that is in usually, therefore, the temperature-controlling air-conditioning that carry out in order to keep normal working temperature each machine room or base station, the electric weight that its accumulation consumes all is no small.The base station that spreads all over the world of GSM for example, on average the power consumption of the annual temperature-controlling air-conditioning in each base station all has degree up to ten thousand.Such mobile communication base station just has 200,000 incessantly in the quantity of the whole of China, and annual power consumption obviously is not a decimal.Because it is very high that the power consumption of air-conditioning accounts for the ratio of mobile communication base station operation power consumption, so air-conditioning economize on electricity question meaning is great.The inventor once applied for " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning " (application number 200610003457.3) of patent of invention, the method that can fully save this class machine room or base station temperature-controlling air-conditioning power consumption exactly on February 9th, 2006.But, " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning " also has weak point, implements cumbersome, can also further improve." power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning two " is exactly to implement simpler, more practical, more reliable, more can economize on electricity and save cost and outstanding effect improvement project than the former.Except economize on electricity,, also just prolonged the service life of air conditioner undoubtedly greatly because the present invention can shorten the working time of air conditioner greatly.This also can obviously save operation cost for enterprise from another aspect.

(2) summary of the invention:

The inventor had once proposed " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning " application for a patent for invention on February 9th, 2006.This patent application realizes the temperature-controlling air-conditioning economize on electricity by comprehensively taking the multiple technologies measure, and mainly comprise: (1) changes original " enclosed system " into " having the semi-open system that can control the air inlet and the exhaust outlet of switching according to the needs of varying environment temperature conditions "; (2) utilization cuts off or adds special-purpose kuppe at the indoor water conservancy diversion that adds of machine room (or base station), the space of Device Host (and exhaust outlet) with air conditioner (and air inlet) place separated, and form the passage that cold and hot air unidirectional sequence flows, original " simple air conditioner temperature control " changed into " utilizing the mobile ventilation of cold and hot air unidirectional sequence that heat is directly given off outdoor method temperature control combines with the air conditioner temperature control "; (3) utilization adds " chimney " (being vertical exhaust duct) at exhaust outlet, forms natural exhaust by the continuous rising of hot-air in " chimney ", ventilates with the method that adopts the air draft of electric power exhaust blower to combine; (4) interface around original machine room (or base station) (top,, wall, door and window etc.) helped outwards heat radiation and be unfavorable for inwardly advancing the transformation of heat.In addition, in the place that water source (on a small quantity) supply is arranged, can also utilize the evaporative cooling that sprays small amount of moisture at the air inlet place further to save air-conditioning power consumption in non-icing season.Whole proposal can also realize regulating automatically and control by temperature control and time control, is used to safeguard the strength of required input with minimizing.

" the air conditioner temperature control method of enclosed system secondary transducing " as previously mentioned, that generally adopt existing machine room or base station, actual is the upper limit that is operated in the air conditioner power consumption.Airtight machine room or base station that thermal source is arranged in this, except the sky when terribly cold by interface (top, the end, door and window, wall) heat radiation just can keep operating temperature not too high, annual overwhelming majority's times all be unable to do without air conditioner and outwards transport heat by the secondary transducing.Generally, in the whole year, the time that outdoor temperature obviously surpasses the indoor equipment operating temperature upper limit (for example 38 ℃) is not many.Therefore, in " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning ", the temperature control operating scheme that the inventor proposes is: adopt " the ventilation temperature control method that cold and hot air unidirectional sequence flows " in most of times of the whole year, the heat that indoor equipment is produced directly is discharged into outdoor; Adopt " the direct discharges heat of ventilation that cold and hot air unidirectional sequence flows shifts heat with the air conditioner transducing and combines " in the higher period at some temperature; And only in minority outdoor temperature too high (air themperature that enters from air inlet surpass the equipment operating temperature upper limit), just adopt the method for the simple air conditioner temperature control of " enclosed system secondary transducing ".Do so not only and can obviously save the power consumption of air conditioner, and the method for " the direct discharges heat of ventilation that cold and hot air unidirectional sequence flows " is also obviously energy-conservation than the method for unordered mixing air intake and air draft than existing simple " enclosed system secondary transducing " method.Simultaneously, transform the door and window wall top cover and the ground of machine room or base station, make it under different ambient temperatures, to have the thermal heat transfer capability that helps keeping the electric equipment normal working temperature, multidirectional outer heat radiation the when the external world is cold and inwardly advance heat when overheated less when extraneous.This obviously also is one of effective way of saving the temperature-controlling air-conditioning power consumption.Adopt the machine room or the base station of " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning ", the power consumption that is used to control air conditioner every year of operating temperature is expected to save about 70% usually.And also can prolong greatly the service life of air conditioner.

In fact, when various operation, in the electric equipment of heating, all have the blower fan that makes the equipment ventilation and heat usually.These blower fans generally have only tens watts power.Even have the machine room or the base station of several these kind equipment work simultaneously, make the power of fan of equipment ventilation and heat add also very limited together.If the hot blast that is blown out equipment by these blower fans directly can be excluded outdoorly, needed power of fan equally can be very not big.But, when when getting rid of these heats, just needing several kilowatts power consumption just can achieve the goal by " method of enclosed system secondary transducing " with air conditioner.Why just be not difficult thus to understand will " enclosed system secondary transducing " simple air conditioner temperature control method change the in line heat that ventilates into and can economize on electricity significantly afterwards.

In unattended equipment room or base station, why people adopt the method temperature control of " enclosed system secondary transducing ", and its thinking also is very natural: at first, in the electric equipment automatically machine room or the base station of operation are arranged, because unmanned just needs door and window to close, and just needs airtight.Enter otherwise just have the inoperative personnel, hinder and damage even steal, also can enter a large amount of dust damage equipments.Because it is outdoor that the heat that produces when can not work equipment in machine room after airtight or base station is lost to,, just need to use the air conditioner temperature control naturally in order to keep the normal working temperature of equipment.All like this both at home and abroad.Because natural, people also just are accustomed to.Do not requiring the energy-conservation age, this working method continues always that to get off be understandable.And exactly on this link, make this class machine room and base station economize on electricity significantly and can accomplish.

But, the scheme implementation that " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning " proposed uses cumbersome, can also be by the further investigation and the utilization of related physical principle, further scheme is simplified and is improved, make will " air conditioner every year power consumption save 70% " the easier realization of target." power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning two " is exactly the further improvement project to " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning ", and energy-saving effect is better, is more convenient for implementing to adopt.For reduction language, below " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning " is called " preceding scheme ", and " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning two " that will propose now is called " back scheme ".Method with contrast is compared " preceding scheme " similarities and differences with " back scheme " below, and passes through the advantage place of comparative descriptions " back scheme ".

(1) " preceding scheme " changes original " enclosed system " into " having the semi-open system that can control the air inlet and the exhaust outlet of switching according to the needs of varying environment temperature conditions "." back scheme " also needs to offer air inlet and exhaust outlet in order to ventilate, but omitted the requirement that air inlet and exhaust outlet " are controlled switching according to the needs of varying environment temperature conditions " than " preceding scheme "." preceding scheme " will open and close air inlet and exhaust outlet control under the different temperatures situation, just gate must be installed at air inlet and exhaust outlet place, but also must installation can the acquisition environment temperature conditions sensor-based system and the control system of gate being carried out different controls according to the varying environment temperature conditions." back scheme " then simply changes " open system " into " enclosed system ".This change has not only been saved according to variations in temperature air inlet and exhaust outlet has been carried out the electronic sensor and the control system of open and close controlling, and simply not be used in air inlet and exhaust outlet place installation gate, makes air inlet and exhaust outlet be in opening-wide state constantly.This not only simplifies the structure and has reduced improvement cost, has reduced the control error that control task also helps reducing because of occurring and has produced mistake, has improved reliability of operation.This change of " back scheme " is not blindly, but is based on the physical analysis basis of whole system.This change simplifies the structure, and but can reach " semi-open system " the same energy-saving effect with " preceding scheme ".

(2) " preceding scheme " changes " simple air conditioner temperature control " into " utilizing the mobile ventilation of cold and hot air unidirectional sequence that heat is directly given off outdoor method temperature control combines with the air conditioner temperature control ".This " single hot-air " scheme is not only energy-conservation than the simple air conditioner temperature control method of original " enclosed system secondary transducing ", and more energy-efficient in indoor unordered mobile " cold and hot air mixing " scheme than air.For this reason, need be at machine room (or base station) indoor adding " water conservancy diversion partition ", or around main frame, add " special-purpose kuppe " for main frame, the space of Device Host (and exhaust outlet) with air conditioner (and air inlet) place separated, and form cold and hot air and can unidirectional sequence flow so that the passage of lowering the temperature more effectively for equipment.Be not have the water conservancy diversion of this standard air sequence of flow to cut off or special-purpose kuppe in " simple heating ventilation and air-conditioning collaborative cooling " (being cold and hot air mixing method) working method.Water conservancy diversion cuts off need open the door that can supply people and equipment to come in and go out, and special-purpose kuppe then can be opened and be sealed as required, and its topology layout is a prerequisite not influence attended operation and management.Angle from gas flow, it is the exhaust outlet that can go directly at an upper portion thereof that water conservancy diversion is cut off (or special-purpose kuppe) total requirement, and the valve (the valve place can also dispose blower fan) that can close of opening that can communicate with air conditioning room also will be arranged at top, and the bottom then is the free-pouring unlimited passage of air that can make two parts space.The valve on top is only too high in ambient temperature, need close inlet and outlet and carry out the room air sealing and circulating, just open during merely with the air conditioner temperature control.Can also start the blower fan at valve place this moment, makes the hot-air of top between main frame flow into air conditioning room, forms circulation.For the situation that adopts kuppe, also the kuppe middle part can be opened wide, make its direct and air conditioning room communication.

Just cold and hot air can be separated (no longer mixing) after adding the water conservancy diversion partition or adding special-purpose kuppe, the orderly of realization room air flowed, and makes the hot-air that has only from the blast pipe discharge, and do not sneak into cool air.That part of space at air conditioner place is cold (cold) end of room air, and its temperature is that indoor temperature is minimum.The space at main frame place is the space of an air themperature distribution gradient.The air of main frame bottom is the same with air themperature between air conditioner, is low-temp. portion.Rise to the top after the main frame heating that the main frame ambient air is generated heat, by outdoor from the exhaust outlet discharge, the cool air of bottom is replenished around rising to main frame again, and plays the effect to the main frame cooling.Therefore, (middle part of special-purpose kuppe) is the moderate temperature position around the main frame, and space, the top between main frame (also being the top of special-purpose kuppe) then is the hot junction of machine room (or base station) room air.

Obviously, the energy-saving effect of " preceding scheme " is unimpeachable, but the structure more complicated, it is also cumbersome to operate.Especially concerning the more mobile communication base station of cable, if add kuppe around main frame, it is cumbersome that the attendant manipulates.

" back scheme " also will utilize partition or kuppe, mozzle with cold and hot air separately, the unidirectional sequence that realizes indoor cold and hot air flows, make the hot-air that has only from the blast pipe discharge, and do not sneak into cool air, so that " simple air conditioner temperature control " changed into " utilizing the mobile ventilation of cold and hot air unidirectional sequence that heat is directly given off outdoor method temperature control combines with the air conditioner temperature control ", has higher energy-saving effect.But, work for the operation maintenance personnel that are more convenient for, use the mobile communication base station that is more suitable for One's name is legion, " back scheme " simplified the setting and the layout of kuppe to greatest extent, kuppe is not located at around the main frame usually, and kuppe is arranged on the position at air conditioner place, then come the standard air to flow in each air inlet with simpler conduction pipe, and, take the interior space less by the wall setting as far as possible, avoid bringing influence and trouble to attended operation personnel's work.And partition that " back scheme " used or kuppe all need not be installed in when being transformed into enclosed system air conditioner temperature control to linking up the valve of the required use of cold and hot air formation indoor circulation, certain control problem of also having saved valve.This simplifies the structure too, has reduced improvement cost, has avoided bringing confusion because of may slipping up that valve is controlled.This helps reducing operate miss equally, improves operational reliability.

(3) " preceding scheme " adopts the method for ventilation that the natural exhaust of not consuming electric power combines with the air draft of electric power exhaust blower.Need add " chimney " (i.e. " vertical exhaust duct ") for this reason at exhaust outlet, utilize " stack effect ", form natural exhaust by the continuous rising of hot-air in " chimney ".At the exhaust outlet place electric power exhaust blower and gate are installed, exhaust outlet then communicates with vertical exhaust duct outward.The air themperature that the gate of exhaust outlet is only too high in outdoor temperature, come in from air inlet is higher than set upper limit and has to and adopts " the airtight transducing working method of air conditioner " time just to close, and all is standard-sized sheet at ordinary times.Air inlet is located at the back of base station, adds that Open Side Down, roomy dust cover (or at the indoor dust cover of setting up).Air inlet can be opened above air conditioner.When intake air temperature is lower than the air conditioner start-up temperature of setting, air conditioner is not worked and (is not only stopped compressor, also need not dry), the cool air that enters from air inlet directly cuts off opening the door to enter between main frame main frame being cooled of (or special-purpose kuppe) bottom from water conservancy diversion; When intake air temperature was higher than setting air conditioner start-up temperature, when ventilating, cooling was worked in coordination with in air conditioner work, and the air after the cooling sinks, and cut off opening the door of (or special-purpose kuppe) bottom through water conservancy diversion and entered between main frame; When the air themperature that is entered by air inlet was also higher than the rated temperature upper limit between main frame, air inlet and exhaust outlet were all closed, and indoor and outdoor is no longer ventilated, and carried out conventional room air sealing and circulating air-conditioning method.

The method of ventilation that " back scheme " adopts the natural exhaust of not consuming electric power to combine with the air draft of electric power exhaust blower equally, need add " vertical exhaust duct " at exhaust outlet equally, add that Open Side Down, roomy dust cover (or be located at dust cover indoor) at air inlet.But, as previously mentioned, the exhaust outlet of " back scheme " and air inlet are not established gate, all are unimpeded any time.For anti-when stuffy dust enter from exhaust outlet, in the exhaust duct porch or the exhaust outlet place also can be added with dustproof filter screen.When outdoor environment temperature was low, for example in winter and early spring and late fall, it was unlikely too high to utilize natural exhaust and interface cooling (back introduction) just can keep indoor temperature; When outdoor environment temperature is not too low, but the temperature difference between air inlet and the exhaust outlet is when also big, can not keep under the situation that room temperature do not rise in gravity-flow ventilation and interface cooling, can start the electric power exhaust blower and strengthen exhaust air rate; When outdoor environment temperature higher, the temperature difference between air inlet and the exhaust outlet is too little, when utilizing the cooling of air draft and interface to be not enough to keep the equipment normal working temperature, because the temperature difference is still arranged between air inlet and the exhaust outlet can be utilized, can also continue to ventilate, but when continuing ventilation, need to start the air conditioner auxiliary temperature-reducing; Reach the upper limit of rated temperature when outdoor environment temperature, when almost not having the temperature difference between air inlet and the exhaust outlet, need not close air inlet and exhaust outlet, only need when air conditioner is worked, close the electric power exhaust blower, no longer forced ventilation just can be carried out the simple air conditioner temperature control with conventional " enclosed system indoor circulation " same effect.When air conditioner was worked, even air inlet and exhaust outlet are all being opened, the hot gas of outside can not come in yet, and the cooler air of the inside can not run out of yet.This just simplifies the structure, and has reduced improvement cost, has avoided bringing confusion because of may slipping up that gate is controlled, and helps reducing operate miss, improves operational reliability.Above-mentioned to the measurement of all temps and under different temperatures to the control of exhaust blower and air conditioner, can adopt electronic sensor and control system to carry out automatically, and need not manually-operated.

Why not be used in air inlet and exhaust outlet gate is installed, just can carry out simple air conditioner temperature control with conventional sealing and circulating air-conditioning method same effect, be because the horizontal level of the air inlet that can link up with the external world and exhaust outlet all than higher, is in the top of machine room or base station wall.When ambient temperature too high, stop the work of electric power exhaust blower, and lower the temperature by air conditioner, when making indoor temperature be lower than ambient temperature, room air proportion is bigger, just can be automatically by outside air inlet or the exhaust outlet delivery chamber, outdoor hot-air can be by in air inlet and the exhaust outlet inlet chamber yet.This moment, air conditioner work was lowered the temperature to indoor air, and its effect can't not have sealing and be subjected to external influence just as being in enclosed system because of air inlet and exhaust outlet.

Be the conduction pipe of setting up by wall in air inlet, the air that enters from air inlet is directed to indoor bottom.Therefore, the cool air in the inlet chamber can't mix mutually with the hot-air of indoor top.The electric power blower fan is equipped with at the air inlet place, need be to the dustproof filter screen dedusting outside the air inlet time, as long as the short time is opened this blower fan, oppositely dries, and just can blow the dust that is deposited on the filter screen off, and need not change filter screen.

(4) " preceding scheme " proposes interface around original machine room or the base station (top,, wall, door and window etc.) helped outwards heat radiation and be unfavorable for inwardly advancing the transformation of heat.For expose in the sun machine room or the end face of base station to add sun-proof mat shelter.Being exposed to the sun and often making a large amount of heats of the sun in summer by in the end face inlet chamber.For expose in the sun machine room or the end face of base station to add sun-proof mat shelter necessary.Sun-proof mat shelter can be erected on machine room or the base station end face with the sheet material (for example cement asbestos shingle) of cheap sun-proof, leaves end face certain distance (for example about 20cm).Its effect is to stop being exposed to the sun of the sun, can be dissipated in the outdoor air unlikely to indoor transmission because of the sun shines the heat that produces again.The existence of sun-proof mat shelter can reduce the indoor temperature of machine room or base station effectively in summer, thereby reduces the power consumption of air conditioner.Especially for those top covers thin machine room or base station, add sun-proof mat shelter and can obviously reduce the air conditioner power consumption, and needed input only is several very cheap asbestos shingles, and be once to drop into every year to be benefited in summer.In order to make sun-proof mat shelter usefulness better, can be below asbestos shingle again cushioning one deck have the foam for panel (or sheet) of aluminum plating reflective membrane.Sun-proof mat shelter will be noted firmly when mounted, in case broken down to get off to hurt sb.'s feelings by big wind.Especially be positioned at the machine room or the base station of eminence, more will take care.

Existing wall, its capacity of heat transmission are the inside and outside two-way same sexes, and promptly the ability of outwards conducting heat is the same with the ability of inwardly conducting heat.Thin wall passes the heat in the external environment into indoorly when it is warm easily, then easily indoor heat is spread out of when ambient temperature is hanged down.Therefore, this is the temperature adjustment factor with dual function.Offset its unfavorable factor for the favorable factor of utilizing it, " preceding scheme " proposes to add " the movable insulated lining " that one deck is made with the plastic foamboard (or sheet) of suitable thickness at thin machine room or base station wall the inside.When summer, it was warm, this layer insulated lining is attached to the exterior wall the inside, can strengthen the heat-insulating capability of wall, the heat that stops the outside effectively is by in the wall inlet chamber; And when outside air temperature was low, this layer insulated lining can be opened as shutter automatically, or by the manual removal, makes wall lose this thermal insulation layer, can strengthen the heat-transfer capability of wall, is convenient to indoor heat and passes through wall.Therefore, there has been this layer can attach or open wide the insulated lining of (or removal) as required, also can have effectively reduced the energy consumption of air conditioner.Can control the attaching and the unlatching of this insulated lining by the temp control switch system automatically, also can when change according to the season, manually attach or remove.The used cystosepiment (or sheet) of insulated lining is preferably with can the thermal-radiating aluminum plating reflective membrane of usable reflection.

" back scheme " will be helped outwards heat radiation and be unfavorable for that " semiconductor-type " that inwardly advance heat transform equally interface around original machine room or the base station (top,, wall, door and window etc.).For expose in the sun machine room or the end face of base station to add sun-proof mat shelter.For thin machine room or the base station of conducting heat easily of wall, be unfavorable for inwardly advancing the transformation of heat for wall being helped outwards heat radiation, " back scheme " do not adopt " preceding scheme " the sort of variable " movable insulated lining ", but at thin and the machine room that thermal insulation is relatively poor or the wall the inside of base station, fixing " the bay wall cavity " of installing one deck.(install one " bay wall " in about 3～10cm) place leaving original machine room wall certain distance.The skeleton of " bay wall " can use various suitable structural lumbers, but need be used heat-barrier material.For example additional plastic foamboard one deck suitable thickness, that do not readily conduct heat (or sheet).Plastic foamboard (or sheet) is preferably with the metal reflective layer, so that external heat radiation is formed stronger reflection." cavity " i.e. that " bay wall " and original between the walls form be " bay wall cavity ".There is one deck can the flow air layer in it.The top of " bay wall " and bottom all have can make the air inflow of " bay wall cavity " and the opening (hole) that flows out, and other parts then seal.The opening of bottom is often opened, and opening part up, have one only allow air from space, indoor equipment place to " bay wall cavity " one-way flow, and the valve (unidirectional lock) that does not allow air to flow to space, indoor equipment place from " bay wall cavity ".Valve can adopt Electronic Control, also can adopt simple air pressure control without Electronic Control.When summer, it was warm, because the heat transfer of wall, air in " bay wall cavity " is heated and lightens and rise, at this moment above the valve of opening part be in closed condition, hot-air can only be suppressed in " bay wall cavity " and can not enter space, indoor equipment place through valve." bay wall " thermal insulation layer of this moment just can play further heat insulation effect, and intensification is caused in the space that makes outdoor heat be not easy to import into by wall the indoor equipment place; When ambient temperature is low (especially winter and early spring, late fall), the air in " bay wall cavity " is cooled off by wall and becomes to avale and fall, and can be automatically enters space, indoor equipment place from the opening of " bay wall " below.Air pressure step-down in this just feasible " bay wall cavity ", the hot-air in space, indoor equipment place just can enter by the valve of unidirectional conducting among " bay wall cavity " smoothly from the opening part of " bay wall " top, forms the automatic convection current and the cooling of indoor sealing.That is to say, there has been this upper and lower to link up and goes up the square channel place and also have " bay wall cavity " to the valve of the unidirectional conducting of air, just can realize " semiconductor-type " transformation automatically " help outwards conducting heat and be unfavorable for inside heat transfer " of original wall with space, indoor equipment place.Make " capacity of heat transmission that wall totally presents " become the two-way opposite sex from the inside and outside two-way same sex.This utilize physical principle realize, to existing heat transfer throught wall ability transformation that carry out, that have breakthrough meaning.The heat-transfer capability of existing wall all is the two-way same sex in the world, and the wall that can have this " semiconductor " formula heat-transfer capability of the present invention's proposition is unprecedented.By contrast, what " preceding scheme " proposed adds " the movable insulated lining " that one deck is made with the plastic foamboard (or sheet) of suitable thickness at thin machine room or base station wall the inside, is a kind of conservation measures, and cumbersome.Can't call wall to the wall of this having " movable insulated lining " with " semiconductor " formula heat-transfer capability.

Machine room or base station for have ready conditions (outdoor have utilizable space) can also add one deck " cooling chamber " outside the wall of machine room or base station." cooling chamber " reality also is one " bay wall cavity ".Only it is installed in outdoorly, and is to be built by the material of firm weather-proof and easy heat transfer.For example use color steel for building to make.The position in " cooling chamber " is installed, and it sticks on the foam thermal insulation plate (sheet) that one deck has reflective metal film by on the indoor wall." cooling chamber " all have up and down can with the ventilative opening of room ventilation.Other places all seal except this opening.Opening part up also have one unidirectional, only allow air in " bay wall cavity ", to flow and valve that mustn't counter current.Valve can adopt Electronic Control, also can adopt simple air pressure control without Electronic Control.When summer, it was warm, the rising of being heated of the air in " cooling chamber ", because top opening is in closed condition, hot-air can only be suppressed in " cooling chamber " and in can not inlet chamber." the cooling chamber " of this moment also can be played certain heat insulation and avoid thermogenic action though can not play cooling effect; When ambient temperature is low, (not only refer to winter and late fall in early spring, even night in summer outside air temperature also often the air themperature than indoor top is low), the decline of catching a cold of air in " cooling chamber ", can be automatically in the opening inlet chamber of " cooling chamber " below, simultaneously, indoor hot-air also can be automatically enters " cooling chamber " by the valve of opening from the opening part of " cooling chamber " top.This has just formed the sealing and circulating of room air, automatically convection current and cooling.That is to say had this top to have " the cooling chamber " of the valve that only allows the air one-way flow, just can realize " semiconductor-type " transformation automatically " help outwards conducting heat and be unfavorable for inside heat transfer " of original wall.Being contained in outdoor " cooling chamber " is consistent with the effect that is positioned on indoor " bay wall cavity ".Outdoor " cooling chamber " is more suitable for the relatively poor machine room of the thicker heat-sinking capability of wall or use the base station.Such as, for the machine room or the base station of using the brick structure wall that does not readily conduct heat, if do the exterior wall in " cooling chamber " at existing wall external application one deck steel plate, and several holes are beaten in top and bottom at the existing wall that constitutes the cooling chamber (inwall in cooling chamber), the hole place sets up the valve of unidirectional admittance up, and hole has enough ducting capacity up and down, that just equal ambient temperature be lower than indoor above during temperature, the wall of machine room or base station is made of one deck steel plate, has good cooling ability and effect.And arrived the higher period of ambient temperature, and because the valve at hole place, top is unidirectional conducting, do not allow hot-air to flow into space, equipment place, the wall of machine room or base station just is equivalent to increase one deck heat shielding again in original wall outside.Remain the very strong steel plate wall of this layer heat-transfer capability, but not only can not pass the heat in the external world into indoorly, can shield extraneous heat on the contrary, make it be difficult to heat original wall, be difficult in the inlet chamber.The steel plate outside can also brush white paint, can strengthen the albedo to sunlight, but does not influence needed heat conduction of cooling and exchange capacity.

Because gate is not installed at the exhaust outlet place of " back scheme ", is in opening-wide state, therefore, no longer adds " sun pump " that can strengthen vertical exhaust duct air draft ability.Otherwise when carrying out simple air conditioner temperature control, indoor cool air can be taken away by the exhaust duct that sun pump has strengthened the air draft ability, causes waste.Because " back scheme " used " cooling chamber " auxiliary temperature-reducing, the load that utilizing ventilates gets rid of heat is less, and needed ventilation is also littler than " preceding scheme ".

In sum, the major technique feature of " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning two " is:

1. with original indoor and outdoor nonventilated fully " enclosed system ", change into and have unlimited air inlet and exhaust outlet, at any time " open system " that can ventilate, and utilization is in the method for machine room (or base station) indoor adding " water conservancy diversion cuts off; kuppe and conduction pipe ", the cool air that enters from air inlet can fully be flowed through needs the equipment of cooling performance cooling effect, rising to exhaust outlet after the heating again drains, at indoor the mobile of unidirectional sequence that carry out, utilize simultaneously can heat insulation and heat control " sun-proof mat shelter " and " bay wall cavity ", machine room (or base station) is helped outwards heat radiation and is unfavorable for inwardly advancing hot " semiconductor-type " transformation in the interface all around, thereby original " utilizing air conditioner to pass through secondary transducing temperature control merely " changed into " utilizing the ventilation that cold and hot air unidirectional sequence flows that heat is directly given off outdoor method temperature control and utilizes effective interface temperature control to combine with the air conditioner temperature control ".

2. for cold and hot air is separated, the unidirectional sequence that realizes indoor cold and hot air flows, make the hot-air that has only from the exhaust duct discharge, and do not sneak into cool air, so that have higher energy-saving effect, the operation maintenance personnel's that also will be more convenient for simultaneously work, the present invention program is arranged on kuppe at the position at air conditioner place, and the air inlet that makes air conditioner is in indoor top, and air outlet is then in the bottom; Simultaneously, the direction that simple conduction pipe comes the standard air to flow is housed all in each air inlet of machine room (or base station),, is directed to indoor bottom by opening air inlet above machine room (or base station) wall from the outdoor cool air that enters.Conduction pipe is provided with by wall, takies the interior space less as far as possible, avoids bringing influence and trouble to attended operation personnel's work.And employed partition or kuppe and conduction pipe all are not mounted for links up the cold and hot air in indoor top to form the valve (gate) of the required use of indoor circulation.

3. adopt the natural exhaust of not consuming electric power to ventilate with the method that the air draft of electric power exhaust blower combines.At the exhaust outlet place of opening wide the electric power exhaust blower is housed, exhaust outlet then is equipped with " chimney " (being vertical exhaust duct) outward.Exhaust outlet communicates with " chimney ".Utilize " stack effect ", form natural exhaust by the continuous rising of hot-air in " chimney ".When weather was cool, simple natural exhaust (and interface cooling) just can be discharged indoor unnecessary heat outdoor; When simple natural exhaust (and interface cooling) is difficult to keep operating temperature and does not raise, just start the air draft of electric power exhaust blower.If environment temperature is higher, but also have the temperature difference between intake air temperature and the exhaust outlet temperature, can in air draft, start the air conditioner auxiliary temperature-reducing; When almost not having the temperature difference between only too high, intake air temperature and the exhaust outlet temperature, just close the electric power exhaust blower, stop forced ventilation, and use the air conditioner temperature control merely in environment temperature.This moment, indoor-outdoor air stopped exchange, had only room air to carry out sealing and circulating.

Vertical exhaust duct can be made with the building plastic pipe of good weatherability.Wall or existing pylon be can rely on, existing wall or pylon just relied on.Do not have ready-made support to rely on, can ride on the simple steelframe of self-support.Because the exhaust outlet place do not have gate, enter dust when preventing outwards air draft, also can add dustproof filter screen at the vertical air draft mouth of pipe or exhaust outlet place.This filter screen can not hinder circulation of air, and should just can blow laying dust off (blowing out outdoor) when beginning to rehearse blower fan.

Air inlet is located at the top of in the shade of machine room (or base station) (the long-time shadow surface of non-sunlight), adds that Open Side Down, roomy dust cover (or at the indoor dust hood of setting up defences).Roomy dust cover can reduce gas-flow resistance, prolongs the dedusting cycle.When dust cover outside the time, a small electric fan (blower fan) can be installed at the air inlet place.Its effect is when the needs dedusting, utilizes of short duration reverse blowing, and the dust that is accumulated on the dust cover filter screen is outwards blown off, reaches the purpose of cleaning filter screen.

Because the difference of the kind model of air conditioner, the moving line of cool hot-air is also not necessarily identical during its work.Therefore need design the corresponding kuppe of processing according to employed dissimilar air conditioner,, avoid cold and hot mixing to stir so that the below that directs into the interior space after the cooling of the hot-air of indoor top.When temperature was lower than the air conditioner start-up temperature of setting, air conditioner was not worked (not only stop compressor, need not dry yet) when indoor (default point for measuring temperature), relied on this moment aeration-cooling the cooling with " cooling chamber " to keep the equipment operating temperature; When indoor temperature is higher than the air conditioner start-up temperature of setting, start air conditioner work, carry out auxiliary temperature-reducing.Ventilate this moment and also continuing.The indoor top air of heat enters from the inlet above the air conditioner kuppe, sunk by cooling cooling back, opening through the kuppe bottom enters the interior space at main frame place, main frame is lowered the temperature, heated the top that air after lightening rises to the interior space by equipment, the part of heat is discharged from higher exhaust outlet, and the part of inferior heat enters air conditioner once more from inferior high air conditioner kuppe air inlet and lowers the temperature; Too high when outdoor environment temperature, when being higher than the rated temperature of setting, stop the work of electric power exhaust blower, stop mandatory ventilation, rely on the air conditioner cooling merely.Here need to prove, because in " open system ", indoor temperature everywhere is also different, therefore, need be according to the concrete condition of each machine room or base station, select one or several promptly " to preset point for measuring temperature " for " the thermometric reference point " of work such as control air conditioner and ventilating fan.Above-mentioned " indoor temperature " is actual to be exactly the thermometric reference point " temperature.

When ventilating, hot-air discharge from exhaust outlet outdoor in, intraventricular pressure good general step-down, outdoor relatively cooler air is just in the air inlet inlet chamber.Cool air in the inlet chamber is downward along the conduction pipe of being close on the wall, enters space, main frame place from the opening of pipeline bottom, and main frame is cooled.Air inlet can have a plurality of, and each air inlet all has the conduction pipe supporting with it.

Because air inlet and exhaust outlet all are in a high position, even air inlet and exhaust outlet are all being opened all the time, the hot gas of outside can not come in yet, and the heavier cool air in the inside can not run out of yet.Therefore, when carrying out the cooling of simple air conditioner, just need not to install gate additional, also need not control naturally gate at air inlet and exhaust outlet place.This has not only reduced cost, has also improved operational reliability.Owing to is exactly conduction pipe in the air inlet, the air that enters from air inlet can directly be directed into the bottom of the interior space through conduction pipe.So the cool air in the air inlet inlet chamber that is in the top does not mix mutually with the hot-air of indoor top.Kuppe and conduction pipe use the bad nonmetallic materials (for example plastics) of heat transfer property to make.

4. interface (end face, wall, door and window etc.) around original machine room (or base station) is helped outwards heat radiation and is unfavorable for inwardly advancing hot transformation.For expose in the sun machine room or the end face of base station to add sun-proof mat shelter.Sun-proof mat shelter can be erected on machine room or the base station end face with cheap building materials (for example cement asbestos shingle etc.), leaves end face certain distance (for example about 10cm).In order to make sun-proof mat shelter usefulness better, can be below asbestos shingle again cushioning one deck have the foam for panel (or sheet) of aluminum plating reflective membrane.Sun-proof mat shelter will be noted firmly when mounted, in case broken down to get off to hurt sb.'s feelings by big wind.Especially be positioned at the machine room or the base station of eminence, more will take care.

In machine room (or base station) wall the inside thin and that thermal insulation is relatively poor, especially inside the wall of sunny slope, one deck is installed is done the partition wall that skeleton is made, form the pattern of " bay wall " with the plastic foamboard that does not readily conduct heat (or sheet) and other sheet material of suitable thickness.This layer " bay wall " leaves the nearly 3～10cm of distance of original machine room wall, and making becomes one " bay wall cavity " between it.There is one deck can the flow air layer in the cavity.Plastic foamboard (or sheet) is preferably with the metal reflective rete, to strengthen thermal-radiating reflection, strengthens effect of heat insulation.The opening that the top of " bay wall " and bottom all have can make the air in " bay wall cavity " flow into and flow out, other parts then are in sealing state.The opening of bottom is often to open (opening wide), and opening part up has a unidirectional lock (valve), is only to allow air to flow in " bay wall cavity " and " valve " that do not allow reverse air flow.Valve can adopt Electronic Control, also can adopt simple air pressure control without Electronic Control.When summer, it was warm, the air in " bay wall cavity " was because of the heat that imported into by the exterior wall rising that lightens, at this moment above the valve of opening part be in closed condition, hot-air can only be suppressed in " bay wall cavity " and in can not inlet chamber.The thermal insulation layer of bay wall this moment (partition) just can play further heat insulation effect; When ambient temperature was low, the wall cooling of suffering from cold of the air in " bay wall cavity " turned cold and descends, and can be automatically enters space, indoor equipment place from the opening of " bay wall " below, was the equipment cooling; Simultaneously, indoorly also can be entered easily among " bay wall cavity ", form automatic convection current and cooling from the opening part of " bay wall " top by the warmed-up hot-air of equipment.That is to say, had in the machine room this upper and lower can both be linked up with space, indoor equipment place and upward the square channel place also has unidirectional unlatching valve " bay wall cavity ", just can realize automatically " semiconductor-type " of " help outwards conducting heat and be unfavorable for inside heat transfer " of original wall transformed, make the become two-way opposite sex of its overall thermal conducting power from the inside and outside two-way same sex.This is to utilize physical principle and the breakthrough transformation to existing heat transfer throught wall ability that realizes.

For machine room with good conditionsi (or base station), can also outside machine room or base station wall, add one deck " cooling chamber "." cooling chamber " reality also is one " bay wall cavity ".Only it is installed in outdoorly, and the exterior wall of cavity is to be built by the material of firm weather-proof and easy heat transfer.For example make with building the color steel that uses in the steel plate room.Add the foam thermal insulation plate (sheet) that posts one deck band reflective metal film in " cooling chamber " by on the indoor wall." cooling chamber " all have up and down can with the ventilative opening of room ventilation.Other places all seal except this opening.Opening part up also has a check valve unidirectional, that only allow air to flow in " bay wall cavity ".Valve can adopt Electronic Control, also can adopt simple air pressure control without Electronic Control.When summer, it was warm, the rising of being heated of the air in " cooling chamber ", because top opening is in closed condition, hot-air can only be suppressed in " cooling chamber " and in can not inlet chamber.This moment " cooling chamber " also can play more effective heat-blocking action though can not play cooling effect; When ambient temperature is low, the decline of catching a cold of air in " cooling chamber ", can be automatically in the opening inlet chamber of " cooling chamber " below, simultaneously, indoor hot-air also can be pushed valve open from the opening part of " cooling chamber " top automatically and enter " cooling chamber ".This has just formed automatic convection current and cooling.That is to say, the valve that has had this top to have only to allow the air one-way flow and " the cooling chamber " of hole, just can realize automatically " semiconductor-type " of " help outwards conducting heat and be unfavorable for inside heat transfer " of original wall transformed, make the become two-way opposite sex of its capacity of heat transmission from the inside and outside two-way same sex.Being contained in outdoor " cooling chamber " is consistent with the effect that is positioned on indoor " bay wall cavity ".Only being contained in outdoor " cooling chamber " is that the interface that utilizes of more frequent active lowers the temperature, when being positioned on indoor " bay wall cavity " and then being mainly used to prevent the summer environment temperature too high to indoor heat transfer.Outside " cooling chamber " can be installed, outside thing side even the wall in the south that facing south, " cooling chamber " can be installed also in the shade wall.When only " cooling chamber " being installed, need install sunshading board additional, avoid shining upon the exterior wall that " cooling chamber " is used to lower the temperature at these positions.Otherwise " cooling chamber " just is difficult to play the effect of cooling.The machine room or the base station of outdoor being equipped with " cooling chamber ", " bay wall cavity " just can be no longer installed at indoor corresponding wall place.

Behind above-mentioned " power-saving method of unattended equipment room (or base station) temperature-controlling air-conditioning two " that adopts that the present invention proposes when the existing machine room that utilizes " enclosed system secondary transducing " mode work fully or base station, only need carry out disposable transformation, the power consumption saving in air conditioner every year that just can be used in the control operating temperature is more than 70%.It is much more that the electricity charge that an average mobile communication base station 1 year is saved are just carried out the expense of above-mentioned transformation than each base station, and this transformation will be once drop into permanent benefited.Simultaneously, owing to adopt the present invention to shorten the working time in air conditioner every year afterwards greatly, also just prolonged the time limit in service life of air conditioner greatly, this has more obviously reduced operation cost from the angle that equipment funds expend.

(3) description of drawings:

Accompanying drawing is the schematic diagram that the mobile communication base station on an independent brick wall cement plate top of building adopts the present invention to transform, the general layout of the main correlation technique key element of having drawn.The original top cover in number mark 1 expression base station among the figure, the wall of 2 expression base stations, the ground of 3 expression base stations, 4 expression communication hosts, the indoor set of 5 expression air conditioners.The off-premises station of pylon, antenna, battery, cable, air conditioner etc. that do not draw in the drawings, other member facilities such as door and window do not draw yet.It below all is base station original dependency basis present technique key element.The technology essential factor that transforming the back increases mainly contains following: at first, increased air inlet 6 and exhaust outlet 7.Dust cover 8 and dustproof filter screen 9 are arranged again outside air inlet, and there is little electric fan 10 at the air inlet place, and mozzle 11 is arranged in the air inlet.At the exhaust outlet place electric power ventilating fan 12 is arranged, vertical exhaust duct 13, and the simple steelframe 14 and the fixing tightwire 15 that add in order to make stable setting of vertical exhaust duct.The air-conditioning kuppe of the supporting design processing of 16 expressions and different model air conditioner.17 represent the exterior wall with the cooling chamber of color steel manufacturing, 18 expression cooling chambeies.The hole that 19 tops, expression cooling chamber and room air are linked up, the unidirectional ventilation valve (being unidirectional lock) at hole place, top, 20 expression cooling chamber.The hole that 21 belows, expression cooling chamber and room air are linked up.Thermal insulation layer by attaching on the wall of the interior space in the 22 expression cooling chambeies.23 are illustrated in the sun-proof mat shelter that the base station top cover adds above.24 are illustrated in the sunshading board that adds outside the cooling chamber of sunny slope.The automatic detection and the control system opening and close of not drawing in the drawings and being used to measure temperature and controlling exhaust blower, air conditioner.Owing to be brick wall, more do not readily conduct heat, be provided with the cooling chamber around therefore only wall outside and do not have at indoor bay wall and the bay wall cavity set up.

(4) specific embodiment:

The example that transform as with a mobile communication base station illustrates the specific embodiment.

(1) original " enclosed system " changed into " open system ".For this reason, need situation, on wall or top cover, leave air inlet and exhaust outlet according to concrete base station.

Air inlet 6 is driveed usually in the shade wall of base station, and the about 20～30cm of distance of indoor ceiling should be left in the position above wall.Can open a plurality of air inlets.Be sealed with mozzle 11 in each air inlet.Mozzle pastes wall from top to bottom and installs, and the air outlet of below is the about 30cm of distance overhead.Air outlet should be with and turn round, and making air-out is flat blowing, rather than blows downwards.The dust cover 8 that Open Side Down is installed outside the air inlet 6.Dustproof filter screen 9 is arranged in the dust cover.Each air inlet place also is equipped with little electric fan 10, of short duration this fan of opening in the time will cleaning filter screen, and oppositely outwards blowing just can blow the dust that accumulates on the filter screen off, and need not change filter screen.

Exhaust outlet 7 is opened usually on the wall or top cover that are convenient to the hot gas discharge on the main frame.Directly or by the hot-air of pipeline communicate in it with the main frame top.And exhaust outlet 7 is in the high position that the indoor hot-air in base station rises, and makes the lighter hot-air of proportion can rise to the exhaust outlet place automatically.There is electric power ventilating fan 12 at 7 places at exhaust outlet, and vertical exhaust duct 13 is arranged outside the exhaust outlet 7.

(2) " simple air conditioner temperature control " changed into " utilizing the mobile ventilation of cold and hot air unidirectional sequence that heat is directly given off outdoor method temperature control combines with the air conditioner temperature control ".Flow for forming cold and hot air unidirectional sequence, except mozzle 11 is all arranged in each air inlet, to be directed to from the outdoor cool air that enters from the air inlet 6 that is positioned at eminence outside the lower of the interior space and level blow out, also need to add kuppe 16 for air conditioner, the hot-air of interior space higher position is introduced air conditioner through kuppe, after the air conditioner cooling, the outlet along continuous straight runs through kuppe 16 belows blows out again.That is to say,, make cool air all be in the bottom of the interior space through the guiding of kuppe 16 and mozzle 11.Have only process equipment 4 " heating " (that is participation) afterwards to after the equipment cooling, the rising that just can lighten, discharge from the exhaust outlet 7 of top the top of the arrival interior space again.Like this, the cool air that enters from air inlet 6 indoor be that unidirectional sequence flows, and be that equipment 4 (communication host) is lowered the temperature in the unidirectional sequence process of flowing.

Air conditioner 5 is rely on to ventilate and the interface cooling is difficult to keep and just starts working when room temperature does not raise, and at this moment, utilizes air conditioner 5 that the portion of hot air on indoor top is cooled off.The position of kuppe 16 inlets is in the position at hot-air place, indoor top.It is too high to have arrived environment temperature, does not almost have temperature difference between exhaust outlet 7 and the air inlet 6, utilizes to ventilate in the time of can not playing cooling effect, closes electric power exhaust blower (fan) 12, and no longer forced ventilation enters simple air conditioner temperature control state.Because in this case natural exhaust effect is also very faint, even does not have natural exhaust, indoor cool air naturally just can delivery chamber yet outside, therefore, just entered room air sealing and circulating state.

(3) method of ventilation that adopts the natural exhaust of not consuming electric power to combine with the air draft of electric power exhaust blower.Adding " chimney " at exhaust outlet 7 is vertical exhaust duct 13, forms gravity-flow ventilation in order to utilize the effect of increasing of hot-air in vertical exhaust duct 13.7 places do not add gate at exhaust outlet.According to the concrete condition of base station, make vertical exhaust duct 13 can rely on the pylon of wall or base station, or establish simple special-purpose steelframe 14 in addition, outside firmly being erected at.The installation position of electric power exhaust blower 12 and direction need be determined according to the concrete condition of each base station.It should be noted that the blowing that produces when making exhaust blower work can flow in the vertical exhaust duct 13 swimmingly, rather than stopped.Be also noted that the selection of exhaust blower fan blade, it can be tried one's best when not working gravity-flow ventilation is not caused resistance.

Vertical exhaust duct 13 (i.e. " chimney ") is located at pushing up by sunny side of base station.The standpipe wall needs sealing, that is to say that " chimney " can not leak gas from top to bottom, otherwise the usefulness of bleeding is not high.Also to make the surperficial blacking of facing south of it it can as often as possible absorb solar energy, the hot-air in " chimney " is further heated, produce bigger last uptrend.

To add rainproof overhead guard above " chimney " with certain dustproof effect.Can use the building plastic pipe to do " chimney ", can also can realize side by side with a thicker pipe with several thinner pipes.

(4) interface (top, wall, door and window etc.) around original base station is helped outwards heat radiation and is unfavorable for inwardly advancing hot transformation.

To add sun-proof mat shelter 23 for the base station end face that exposes in the sun.Sun-proof mat shelter can be erected on the base station top cover 1 with the cement asbestos shingle of cheap sun-proof, leaves end face certain distance (for example about 10cm).Its effect is to stop being exposed to the sun of the sun, can be dissipated in the air not to indoor transmission because of the sun shines the heat that produces again.In order to make sun-proof mat shelter 23 usefulness better, can be under asbestos shingle again cushioning one deck have the foamed sheet of aluminum plating reflective membrane.Above-mentioned to add the required cost of sun-proof mat shelter 23 very low, but has the usefulness of permanent use, can save a large amount of electric power changes of air conditioners for the base station every year.Certain attention fixed when sun-proof mat shelter 23 was installed, and avoided being scratched the generation security incident by strong wind.

For the thin base station that is easy to conduct heat of wall, outside thin sunny slope, can increase one deck " bay wall cavity " within the walls.Utilize batten and three-ply board to do skeleton and set up one " bay wall ", attach the plastic foamboard of the about 2cm of a bed thickness on the bay wall in cavity, also can will have aluminum plating reflective membrane with thin foamed plastics film." bay wall " top has several holes, and be equipped with and only allow the unidirectional valve that flows of air in " bay wall cavity " at the hole place." bay wall " bottom also has some ventilative holes, but does not have valve.

Thicker for wall, as not readily conduct heat base station in order to strengthen the thermolysis of wall, also can increase one deck " bay wall cavity " outside thicker wall.Because this layer " bay wall cavity " 18 mainly has been the cooling effect, therefore also cries in " cooling chamber ".The exterior wall that is built up in outdoor " bay wall cavity " is made with color steel.Color steel not only conducts heat easily, and sturdy and durable." bay wall cavity " 18 is by attaching the plastic foamboard of the about 2cm of a bed thickness on the indoor wall.Also can use thin foamed plastics film, have aluminum plating reflective membrane." bay wall cavity " 18 has several holes 19 by indoor wall top, and be equipped with and only allow the unidirectional valve 20 that flows of air in " bay wall cavity " (i.e. " cooling chamber ") at hole 19 places." bay wall cavity " also has some ventilative holes 21 by the bottom of indoor wall, but do not have valve.

In above-mentioned modification scheme, really need control automatically, be open and close according to the variation control electric power ventilating fan of environment temperature and main frame place space temperature, and the open and close of control air conditioner.For this reason, need settle temperature sensor, measure the temperature at air inlet and exhaust outlet place at air inlet and exhaust outlet place, and according to the temperature value and the temperature difference of air inlet and exhaust outlet, when utilize automatic control system, determine the turns on power ventilating fan, when open air conditioner." bay wall cavity " also needs to install corresponding electronic surveying and control system if hole place, top installs is electronically controlled check valve.According to the temperature difference of " bay wall cavity " interior and exterior wall is the negative just open and close that decide valve, makes that air can only be from equipment place spatial flow to " bay wall cavity " and can not reverse flow; If what use is air pressure control valve, can be without electronic control system, when and temperature " bay wall cavity " in higher when the temperature above the space, indoor equipment place is low, the cooler air of temperature has been fallen by exterior wall in " the bay wall cavity " of sealing, becoming heavy descends afterwards, flow into space, equipment place from the hole of bay wall below, make airtight " bay wall cavity " air pressure step-down, the valve at hole place, bay wall top will be backed down automatically by the air of top, space, equipment place, makes to enter " bay wall cavity " than hot-air.The cooling of formation sealing and circulating.And when the lower and temperature " bay wall cavity " in of the temperature of space, indoor equipment place top was higher, valve was closed in air rising in " bay wall cavity ", and hot-air can not flow to space, equipment place by valve.Because bay wall has simultaneously increased thermal insulation layer by the lining, the hot-air in " bay wall cavity " also is difficult to heat is passed into space, indoor equipment place.Like this, when the higher and indoor temperature of ambient temperature was low, " cooling chamber "---what just " bay wall cavity " rose was heat-blocking action.

After carrying out above-mentioned transformation, in environment temperature lower winter and late fall in early spring, the base station machine of not only need not turning on the aircondition, nor with driving the electric power exhaust blower, utilizing the cooling of natural exhaust and interface just can keep the base station indoor temperature can be not too high; Spring and autumn the sky and summer common temperature night, the machine of also need not turning on the aircondition usually as long as there have cooling of gravity-flow ventilation, interface and electric power air draft just can keep room temperature to be not too high, just opened air conditioner in case of necessity and is assisted to lower the temperature; Only use the cooling of air conditioner sealing and circulating separately in the minority period in summer.This has obviously saved the power consumption of air conditioner greatly, has also prolonged the service life of air conditioner greatly.
