Description
Technical field
The invention belongs to heat pipe air conditioner all-in-one technical field, particularly a kind of heat pipe air conditioner integrative machine and method for designing with phase-change cold-storage device.
Background technology
At present, along with the increase of the soaring and environmental pressure of energy cost, energy-conservationly become social mainstream values.And building energy consumption shared proportion in social total energy consumption is larger, the energy consumption of air-conditioning has accounted for again very large proportion in building energy consumption.Therefore, exploitation air conditioner energy saving technology, reduction air conditioning energy consumption are the important topics in industry.
Due to the uncertainty of indoor and outdoor surroundings, cooling condition is very complicated.Wherein, the fast development in communication base station, machine room, clean room, clean warehouse etc. in recent years, its highly effective refrigeration technology becomes a focus of people's research.Owing to the requirement of room air cleanliness factor cannot being carried out to direct ventilation heat exchange or indoor thermal source discharges more heat and cannot simply reduce many reasons such as indoor temperature by ventilation, the occasion that needs to start refrigeration system in the situation of indoor temperature higher than outdoor temperature is comparatively common.Take southern area as example, among 1 year the temperature of outdoor air below 20 degree and the duration of relative humidity below 50% roughly about 200 days, and the temperature that base station and clean room need to be controlled is generally greater than 20 degrees Celsius.Due to inside of base station unit release heat, even if therefore, still need to enable air-conditioning and freeze during lower than indoor target temperature in environment temperature.In this case, how making full use of Environmental cold source becomes energy-conservation a kind of important channel, makes full use of Environmental cold source the technical development of refrigerating field has been proposed to new requirement.
In view of the situation and demand, people have developed a series of technology, and wherein the important technology of a class is heat pipe air conditioner all-in-one.In environment temperature, during lower than indoor temperature certain value, the type unit starts heat-pipe refrigerating system automatically, and in the time that environment temperature is close to or higher than indoor temperature to certain value, the type unit starts air-conditioning refrigeration system automatically.Because environment temperature in the middle of a year is more lower than the time of indoor temperature, the power consumption of heat-pipe refrigerating system is far above the power consumption of air conditioner refrigerating.Therefore, heat pipe air conditioner all-in-one is a kind of important technology that reduces energy consumption for cooling.For air-conditioning heat pipe integrated machine, people have developed a series of patented technology at present, and the patent of having applied at present comprises CN 202350223 U, CN 102297487, CN 102748824 A, CN 103134129 A, CN 103307683 A etc.So-called heat pipe air conditioner all-in-one, has two kinds of different structural forms at present, and one is that heat pipe and air-conditioning have independently condenser and evaporimeter, and another kind is that heat pipe and air-conditioning share a set of condenser and evaporimeter.In the first situation, respectively build a set of condenser and evaporimeter due to heat pipe and air-conditioning, system is more complicated, and efficiency is lower and obviously increased equipment cost; In the second situation, due to shared a set of evaporimeter and condenser, and operation of air conditioner operating mode is obviously different from heat pipe operating condition, causes the needed evaporimeter of operation of air conditioner to move needed heat exchange area with the heat exchange area of condenser with heat pipe and does not mate.Heat pipe moves needed heat exchange area and is greater than the heat exchange area of operation of air conditioner, once and press the needed heat exchange area configure of heat pipe, obviously increase again the cost of equipment.Especially in the time that existing air-conditioning system is transformed, the condenser of air-conditioning and the heat exchange area of evaporimeter are determined, are difficult to transform again.In this case, while only having environment temperature to reach a higher value lower than indoor temperature, enable hot-pipe system and could meet refrigeration demand, and this greatly reduces the time of the applicable operation of heat pipe, causes energy-saving effect not obvious.Therefore, traditional heat pipe air conditioner all-in-one there is no method and plays theoretic energy-saving effect in application.
Meanwhile, the interior volume zones of different in communication base station, machine room, factory building, warehouse etc. often exists and requires to control the inconsistent situation of temperature.Taking communication base station as example, the suitable environment temperature that battery region requires is 15-25 degree Celsius, and main equipment and power-supply device can normally be worked 30 degrees Celsius of left and right temperature.Regulate the temperature in base station if press the optimum temperature of battery, can cause the waste of a large amount of colds.Conventional heat pipe air conditioner all-in-one cannot carry out temperature adjusting in subregion, cannot play the effect of accurate adjusting, thereby not reach due energy-saving effect.
In addition, in order to solve different period imbalance between power supply and demand, implementing time-of-use tariffs becomes a trend.Paddy electricity electricity price, compared with peak electricity electricity price, differs three times of left and right even more than three times.And conventional air-conditioning cooling time is just in time peak electricity traffic coverage, not only increase electricity price, reduce refrigerating efficiency (evening, environment temperature was low, and refrigerating efficiency is high), and increased the pressure of electrical network.Therefore, utilize paddy electricity refrigeration excessive significant to alleviating in the interval power load of peak electricity.Conventional heat pipe air conditioner machine cannot be selected the time period of refrigeration, therefore also just cannot realize the advantage of utilizing paddy electricity.
In addition, due to the fluctuation (comprising temperature, wind-force, rainfall etc.) of environmental condition, and the problem of Control System Design, conventional heat pipe air conditioner all-in-one exists and switches more frequently air-conditioning refrigeration system and the operation of heat-pipe refrigerating system, has caused the increase of energy consumption.Allow the system can even running in long period section, the reliability that reduces energy consumption and increase system is had to remarkable effect.
In view of the foregoing, due to difficulty and the accurate problem of control band temperature in the selection of heat exchange area, cannot utilize paddy electrical dominance simultaneously, also there is frequent switch air-conditioning refrigeration system and the operation of heat-pipe refrigerating system, cause the problems such as energy consumption increase, the energy-saving effect of conventional heat pipe air conditioner all-in-one is not obvious.For above-mentioned situation, the present invention proposes a kind of heat pipe air conditioner all-in-one technology with phase-change cold-storage device, has important practical be worth for the application that advances heat pipe air conditioner all-in-one.
Summary of the invention
The problem existing for existing heat pipe air conditioner all-in-one technology, the present invention proposes to introduce phase-change cold-storage device in heat pipe air conditioner all-in-one.Store the technical scheme of cold and released cold quantity by the intelligence of phase-change cold-storage device, the running status of adjusting heat pipe air conditioner all-in-one that can be good, reaches and makes full use of paddy electricity refrigeration.In the situation that between environment temperature and indoor temperature, the temperature difference is less, can carry out by the cold of phase-change cold-storage device the deficiency of supplemental heat pipe refrigerating capacity, make heat-pipe refrigerating system in the stable operation of the interval energy of most of environment temperature, realize and make full use of natural cooling source.The effect of phase-change cold-storage device also helps heat pipe air conditioner all-in-one not to be needed frequently to switch refrigeration mode, makes system even running in a long time, gives full play to the energy-saving benefit of heat pipe air conditioner all-in-one.Simultaneously, phase-change cold-storage device can be in parallel a set of or overlap more, on every cover phase-change cold-storage device, connected a set of hot-pipe system, and every cover hot-pipe system can independently regulate an interval temperature, thereby can regulate indoor temperature in by stages, reach the feature of accurate control temperatures at localized regions.In addition, the heat pipe air conditioner all-in-one with phase-change cold-storage device that the present invention proposes also can Based Intelligent Control complete cold-storage in paddy electricity interval, makes full use of refrigerating efficiency and paddy electricity electricity price under relative low temperature environment at night, all has obvious effect for energy-conservation and power cost saving.In addition; because heat pipe air conditioner all-in-one proposed by the invention is with phase-change cold-storage device; when air-conditioning unit occur any accident cause shut down situation under; cold in phase-change cold-storage device still can ensure that key equipment normally moves a period of time; significant for the harm of maintenance system even running, reduction equipment heat, also for emergency maintenance provides the valuable time.

Detailed description of the invention
Embodiment mono-: as shown in Figure 2, this heat pipe air conditioner all-in-one comprises two phase-change cold-storage devices (7) and triple valve (6) is controlled the flow that enters respective phase change regenerator.The phase-change material (15) of different phase transition temperatures is housed respectively in two phase-change cold-storage devices (7), and two phase-change cold-storage devices (7) comprise respectively the heat exchanger (8) that is communicated with refrigeration system and the heat exchanger (9) with external heat exchange.Heat exchanger (9) and the heat exchanger (11) that is placed in incubator (10) together with, and control the circulation situation between heat exchanger by stop valve (12) respectively.This heat pipe integrated machine with two or more phase-change cold-storage devices is applicable to being applied to needs simultaneously and regulates the occasion of several local temperatures.
Embodiment bis-: as shown in Figure 3, when environment temperature is during higher than certain value, heat pipe air conditioner all-in-one starts air-conditioning refrigeration system automatically.From evaporimeter (14) low pressure gaseous working medium out, because condenser end temperature is high, substantially can not pass through by check valve (2).Therefore working medium can be sucked by compressor (1).The low pressure gaseous working medium sucking is after compressor (1) pressurization, become high-pressure gaseous working medium, and enter condenser (3), release heat in condenser (3), condense into high-pressure liquid working medium, high-pressure liquid working medium is introduced expansion valve (4), in expansion valve (3), become low-pressure liquid working medium through isenthalpic expansion, described low-pressure liquid working medium enters triple valve (6) again, triple valve, according to the temperature in environment temperature, indoor actual temperature, indoor target temperature and phase-change cold-storage device (7), regulates the working medium flow that enters phase-change cold-storage device (7).In the time that phase-change cold-storage device not yet reaches design temperature, air-conditioning refrigeration system regulates the flow of low temperature liquid working medium automatically, part working medium directly enters fluid reservoir (13), part working medium enters phase-change cold-storage device (7), by the cold of heat exchanger one (8) absorption cycle working medium that immerses phase-change cold-storage device (7), cause part low temperature liquid working medium can evaporate formation gaseous state, via pipeline, by the working medium access fluid reservoir (13) of partial gasification, wherein liquid refrigerant enters kind of refrigeration cycle.In the time being less than setting minimum of a value in liquid refrigerant in fluid reservoir (13), automatically adjust the aperture that triple valve (6) enters phase-change cold-storage device (7), reduce and even close the cryogenic fluid that enters phase-change cold-storage device (7).Until liquid refrigerant liquid level is higher than when setting value, again increase or open the aperture of triple valve (6), increase the working medium flow that enters phase-change cold-storage device (7), the phase-change material in phase-change cold-storage device (7) is freezed.Repeat said process, reach design temperature until reach phase-change cold-storage device.In the time that the temperature in phase-change cold-storage device has reached design temperature (lower than the phase transition temperature of phase change cold-storage), all working medium directly enters fluid reservoir (13), carries out kind of refrigeration cycle, until while reaching the temperature of indoor setting, air-conditioning refrigeration system temporarily quits work.
In addition, the heat pipe air conditioner all-in-one of the band phase-change cold-storage device (7) that the present invention carries, can Based Intelligent Control preferentially carry out cold-storage at paddy electricity traffic coverage, thereby guarantees to utilize Low Night Temperature environment temperature and paddy electricity electricity price to freeze.
Embodiment tri-: as shown in Figure 4, when environment temperature when (this setting value is by the exchange capability of heat of target indoor temperature, environment temperature and condenser and evaporimeter), is enabled heat-pipe refrigerating system lower than setting value automatically.In the time using hot-pipe system refrigeration, by check valve (2), condenser (3), magnetic valve (5), triple valve (6), fluid reservoir (13), evaporimeter (14) and the pipeline composition working medium circulation loop that is connected successively above-mentioned each mechanism, by magnetic valve (5) liquid refrigerant out, via triple valve (6) adjust flux, controlled the flow that enters phase-change cold-storage device (7) by triple valve (6), part working medium flow directly enters fluid reservoir (13), part working medium enters fluid reservoir (13) after via phase-change cold-storage device (7), fluid reservoir (13) regulates the liquid level of working medium, liquid refrigerant sucks evaporimeter (14), described liquid refrigerant temperature in absorption chamber in evaporimeter becomes gaseous working medium, described gaseous working medium is directly via check valve (2), enter condenser (3), release heat in condenser, liquefy working medium, described liquid refrigerant access magnetic valve (5), form the heat-pipe refrigerating system of a sealing.
When environment temperature is lower than indoor temperature certain value, and during higher than the phase transition temperature of phase-change cold-storage device (7), there is triple valve (6) to control the working medium flow that enters heat of transformation cooler.In the time that system judges that the temperature difference of environment temperature and indoor temperature is greater than setting value, evaporimeter can effectively carry out effective temperature adjusting to environment, now, triple valve (6) regulates liquid refrigerant not enter phase-change cold-storage device (7), phase-change cold-storage device (7) utilizes the stored cold of phase-change cold-storage device (7), by heat exchanger (9) and heat exchanger (11), incubator (10) is freezed.In the time that system judges that the temperature difference of environment temperature and indoor temperature is less than setting value, when the liquid refrigerant being flow through by condenser (3) cannot effectively be reconciled indoor temperature, regulated the working medium flow that enters phase-change cold-storage device (7) by triple valve (6), working medium absorbs the cold of phase-change material in heat exchanger one (8), enter fluid reservoir, and together complete the adjusting to indoor temperature from the liquid refrigerant of condenser (3).
When environment temperature is simultaneously lower than indoor temperature certain value, and during lower than the phase transition temperature of phase-change cold-storage device, there is triple valve (6) to regulate the working medium flow that enters heat of transformation cooler.When phase-change cold-storage device (7) not yet reaches design temperature (lower than material phase transformation temperature), and the cold of cycle fluid is greater than when indoor temperature is regulated to needed cold, unlatching or increase triple valve (6) enter the working medium flow of phase-change cold-storage device, and unnecessary environment cold is stored in phase-change cold-storage device (7).In the time that phase-change cold-storage device (7) reaches design temperature, triple valve (6) reduces or closes the working medium flow that enters phase-change cold-storage device (7), and described working medium all circulates for heat-pipe refrigerating.In the time that indoor and outdoor reaches setting value, heat-pipe refrigerating system stops automatically.
Above regulative mode has improved the running time of heat-pipe refrigerating system greatly, and concrete schematic diagram as shown in Figure 5.When with phase-change cold-storage device (7), phase-change cold-storage device can (7) with the deficiency of part supplemental heat pipe refrigerating capacity.Even if environment temperature and indoor temperature are poor less, also can start heat-pipe refrigerating system.Be equivalent in the time not being with phase-change cold-storage device (7), while needing environment temperature lower than B point, just can start heat-pipe refrigerating system, and when with phase-change cold-storage device (7), when temperature can start heat-pipe refrigerating system lower than A point.Obviously, Δ t in Fig. 5
