Detailed description of the invention
Below with reference to the accompanying drawings the specific embodiment of the present invention is described:
Fig. 1 is damping thermoregulating system integral system schematic diagram.
As shown in Figure 1, damping thermoregulating system 100, has temperature control portion, heat convection stores wet unit and regeneration of waste liquor unit.Wherein, temperature control portion comprises evaporimeter 1, choke valve 2, compressor 3 and condenser 4.These four parts form a loop, control the temperature of indoor.Heat convection stores wet unit and comprises convection current drum 12 and base 18.Regeneration of waste liquor unit comprises solution regenerator 5 and solution heat exchanger 7, is connected between solution regenerator 5 with base 18 by the first pipeline 16 with second pipe 17.Store wet liquid (only show in figure its flow to) to be stored between wet unit and regeneration of waste liquor unit 5 at heat convection by the first pipeline 16 and second pipe 17 and circulate.Evaporative cooling unit has plate type heat exchanger 10 and the 3rd circulating pump 9.According to the difference heated with refrigeration mode and indoor humidity and outdoor temperature of air-conditioning, native system can regulate the temperature of room air 15.
When Summer Indoor temperature and humidity is all higher, temperature control portion opens, cooling operation is carried out to indoor, the exhaust outlet of condenser 4 is to outdoor discharge hot-air 13, now control part (not shown) control triple valve makes the air outlet of condenser 4 provide hot blast to solution regenerator 5, and 13 in Fig. 1 shows the direction of motion of hot blast.Hot blast heats the wet liquid that stores in solution regenerator 5, makes to store the water evaporates in wet liquid, thus formed high concentration store wet liquid.The wet liquid that stores of high concentration enters convection current drum 12 by the first pipeline 16, and flows down from its surface, and saturated solution absorbs the moisture in room air 15, thus reaches the effect of dehumidifying.Saturated solution concentration after absorbing moisture in air declines, and is entered in solution regenerator 5 again concentrate after base 18 is collected by second pipe 17.
Simultaneously, devaporizer 8 is connected to the outside of the first pipeline 16, by plate type heat exchanger 10 for storing the cooling of wet liquid after concentrated, thus make to enter indoor high concentration to store wet liquid temp lower, in absorption room air 15 while moisture, play the effect of auxiliary temperature-reducing.
Control part (not shown) Real-Time Monitoring is indoor with outdoor humidity, when outside air humidity compare room air 15 humidity low time, control part can control triple valve, guides outdoor dry air 14 to enter solution regenerator 5, concentrates the wet liquid that stores wherein.
When winter, indoor temperature was lower, temperature adjustment portion heats operation to indoor.Now indoor temperature is more outdoor high, and due to indoor temperature high, indoor humidity declined accordingly, when storing the surface of wet liquid from convection current drum 12 and flowing down, moisture content can be discharged by the air heat of indoor, room air 15 be played to the effect of humidification.Meanwhile, the solution concentration flowing through convection current drum 12 rises, and the wet liquid that stores of high concentration is entering solution regenerator 5 after second pipe 17, now the moisture stored outside wet liquid absorption chamber of high concentration, thus concentration declines.The wet liquid that stores after concentration declines enters in convection current drum 12 by the first pipeline 16, again to indoor release moisture.During winter operation, devaporizer 8 cuts out.Control part controls triple valve, closes the cold wind in condenser 4 direction, makes solution regenerator 5 moisture exchange directly and between outdoor air.
Solution heat exchanger 7 is connected between the first pipeline 16 and second pipe 17, be provided between the first pipeline 16 and second pipe 17 and heat exchange occurs, such as when summer operation, because indoor temperature is lower, therefore by flowing in second pipe 17 to store wet liquid temp also lower.Store wet liquid owing to being heated by outside air simultaneously through solution regenerator 5, therefore temperature is higher.Can heat exchange be there is between first pipeline 16 and second pipe 17 of solution heat exchanger 7, thus make the wet liquid that stores flowing through the first pipeline 16 have preliminary cooling-down effect, and then further lower the temperature through plate type heat exchanger 10.
When winter operation, in second pipe 17 to store wet liquid temp higher, the wet liquid that stores in solution heat exchanger 7 pairs of second pipes 17 produces pre-heat effect, makes to enter indoor solution temperature and rises.
The power of solution flowing is from the first circulating pump 11 be connected on the first pipeline 16 and the second circulating pump 6 be connected on second pipe 17.First pipeline 16 with second pipe 17 are connected with solution heat exchanger 7, make the storing between wet liquid in wet liquid and second pipe 17 that store in the first pipeline 16 that heat exchange occur.First pipeline 16 is connecting plate type heat exchanger 10 after solution heat exchanger 7, plate type heat exchanger 10 is also connected with devaporizer 8, devaporizer 8 provides cold water to plate type heat exchanger 10, and the store wet liquid heated through hot-air 13 is cooled, make to enter the indoor wet liquid temp that stores through the first pipeline 16 to reduce, thus bring better cooling-down effect while dehumidifying.Circulating pump 9. is connected with between devaporizer 8 and plate type heat exchanger 10
Storing wet liquid is mixing salt solution, and its solute is mixed by the calcium chloride of the lithium bromide of 40%-70%, the lithium chloride of 20%-50% and 5%-20%, and the formation saturated solution that adds water.
Embodiment effect and effect
In traditional air-conditioning system, add heat convection according to the damping thermoregulating system of the present embodiment and store wet unit and regeneration of waste liquor unit, and circulation stores wet liquid wherein, utilization stores wet liquid and flows from top to bottom among convection current drum, form solution film, solution and room air is made to carry out the wet heat exchange of heat, the moisture in room air can be stored, microenvironment humidity is controlled within the specific limits, thus reach the effect storing wet temperature adjustment, and be connected with air-conditioning system, bear the hot humidity load of indoor section, improve the efficiency of whole air-conditioning system.
In addition, owing to present invention employs control part, therefore, Energy Recovery Technology is utilized when outside air humidity is higher, regenerative brine is carried out by the mode absorbing air conditioner condensation heat, reduce the energy consumption of air-conditioning system, also for indoor provide refrigeration while regenerative brine, reach the effect of energy-saving and emission-reduction.When outside air humidity is lower, make full use of outdoor dry air energy, adopt outdoor dry air directly and concentrated solution convection current, take away portion of water in weak solution, thus carry out regenerative brine, reduce the consumption of the energy.
On the other hand, owing to present invention employs devaporizer and plate type heat exchanger, after regeneration, salting liquid first carried out heat exchange with the cold water from devaporizer before entering convection current drum, owing to there is temperature difference at the dynamic salting liquid of the wet outside of deivce surface current of heat convection-store and room air, therefore salting liquid and room air have good heat convection effect, reduce air-conditioning system total energy consumption.
The mixing salt solution that heat convection in the embodiment of the present invention-solution stored in wet device adopts a kind of lithium bromide, lithium chloride, calcium chloride to make according to a certain percentage, solution is along heat convection-storing wet apparatus surface flows from top to bottom, the moisture in room air can be stored, microenvironment humidity is controlled within the specific limits, can also indoor temperature be regulated, reach the effect storing wet temperature adjustment.
In addition, owing to have employed solution heat exchanger in the present embodiment, carry out preheating or precooling to storing wet liquid in different situations, thus further increase efficiency of energy utilization.
