Description
Affiliated technical field
The present invention relates to the air conditioner that a kind of indoor air temperature is regulated machine (being designated hereinafter simply as " air conditioner "), the especially method of air conditioner temperature adjustment and utilized the method work operation.
Background technology
Present indoor air conditioner does not all adopt real cold-storage method.The evaporating temperature of the present employed refrigerant of air conditioner generally is between-5～15 ℃, its workflow mainly is: the refrigerant of air conditioner is in the kind of refrigeration cycle of a sealing, after processes such as compressed, cooling, throttling, decompression, cooling liquefy, flow directly in the evaporation tubes of indoor condenser.Refrigerant carries out cold and hot exchange by heat-exchanging component in the condenser and the Air Conditioning in the condenser air concentrator of flowing through in evaporation tubes, and after cold and hot exchange, refrigerant is subjected to thermal evaporation and released cold quantity, and Air Conditioning then reaches the purpose of loss of heat cooling.Therefore, in the workflow of present air conditioner, can find: after compressor of air conditioner is out of service, evaporation tubes in its condenser will lose thereupon can be for the liquid refrigeration medium of heat absorption evaporation, and air conditioner also carries out cold and hot exchange with regard to stopping immediately with Air Conditioning.Because the restriction of conditioned space, its relative space thermal capacity is very limited.Under the thermal capacitance quantitative limitation of space, during operation of air-conditioner, its conditioned space temperature is certain to exist the phenomenon that cooling is fast, intensification is also fast.Therefore, present air conditioner also has only the method that adopts frequent operation compressor, could comparatively balancedly guarantee the design temperature of conditioned space.The result of high frequent start must cause electric energy to start the increase of loss.In addition, though present air conditioner also utilizes aluminum intensive on the condenser or other metal fin to play certain cold-storage effect, but because of the thermal capacity of material is too little, the cold-storage ability is extremely limited, so also do not reach the effect that alleviates high frequent start phenomenon basically.
At present, in order to reach object of energy saving, people require to reduce conditioned space, even allow conditioned space be compressed to a hope within the bed scope that only is used to ensure the nighttime sleep needs to become more and more stronger.And if the method for regulating temperature and the air conditioner of air conditioner are put into when using on the littler conditioned space at present, when being used for a bed scope that only is used to ensure the nighttime sleep needs and using, the fact of dwindling space thermal capacity significantly that it causes must make the phenomenon of high frequent start become more serious.Thereby the method for regulating temperature of air conditioner and air conditioner not only exist the high frequent start to cause electric energy to start outside the bigger shortcoming of loss at present, have also limited people and have reached object of energy saving by reducing conditioned space.
Summary of the invention
For high frequent start, the especially problem of the frequent start of appearance when little conditioned space moves that overcomes present air conditioner.The invention provides the method and the cold-accumulating air conditioner of the temperature adjustment of a kind of air conditioner cold-storage.Utilize the method for cold-storage temperature adjustment to use cold-accumulating air conditioner can prolong the time that compressor of air conditioner is shut down relatively; reduced the electric energy loss of compressor start; increased the constant temperature degree of conditioned space, can also satisfy people and reach the hope of energy efficiency purpose by dwindling conditioned space.
The technical solution adopted for the present invention to solve the technical problems is:
In the workflow of air conditioner, increase a process of cool and a cold-storage temperature adjustment process.In process of cool and cold-storage temperature adjustment process, utilize a kind of liquid or gluey material that but loss of heat solidifies under the evaporating temperature of air conditioner refrigeration medium to serve as cool storage medium, this cool storage medium can be saved cold by the process that discharges a large amount of heats when entering the loss of heat process of setting by liquid or gluey, when this cool storage medium then can will be saved cold by the process that absorbs a large amount of heats when the mistake cold cut is separated process and be discharged by solid-state entering.
Save cold in order to cooperate cool storage medium, accessories such as the compressor that uses in this air conditioner that utilizes the cold-storage method for regulating temperature, capillary, the evaporating temperature of the refrigerant that can be enough to make it corresponding suitable when its work is lower than the necessary temperature of cool storage medium condensation cured.
The air conditioner that utilizes the cold-storage method for regulating temperature is in workflow, above-mentioned cool storage medium is contained in the regenerator, after the liquefaction of processes such as refrigerant is compressed, cooling, throttling, cooling, before the inlet chamber inner condenser, enter in the evaporation tubes that is provided with in this regenerator and finish the heat absorption evaporation process, simultaneously in the regenerator under the effect of cool storage medium set heat-exchanging component in regenerator of splendid attire with evaporation tubes in refrigerant cold and hot exchange takes place and enter the process that the cooling loss of heat solidifies, both entered process of cool.
When refrigerant is finished the heat absorption evaporation process in regenerator after, send in the room air condenser of air conditioner, continuation is finished condensation process to the Air Conditioning that circulates in the room air condenser with its residue cold, sucks and enter next kind of refrigeration cycle by compressor of air conditioner then.
In the workflow of air conditioner, when the cool storage medium in the regenerator soon all will be condensed curing, the loss of heat amount of cool storage medium also constantly descends thereupon, the refrigerant that the can not get enough evaporation heats evaporation process of will absorbing heat is extended in the indoor condenser of air conditioner, strengthen the heat exchange amount of indoor condenser to Air Conditioning, the cooling extent of Air Conditioning is constantly increased, when the Air Conditioning temperature by indoor condenser drops to when being enough to make the temperature sensor generation braking action that is provided with in the air conditioner, compressor of air conditioner is out of service and cause the kind of refrigeration cycle of refrigerant also to stop thereupon.After the kind of refrigeration cycle of refrigerant stops, the aerial condenser that Air Conditioning begins to be provided with from regenerator circulates, and carry out cold and hot exchange with cool storage medium after the condensation cured, cause cool storage medium released cold quantity and liquefacttus gradually, Air Conditioning is then obtained cold and has been reached temperature adjustment purpose after compressor of air conditioner is out of service, has both finished cold-storage temperature adjustment purpose.
Utilize the initial stage of the air conditioner of cold-storage method for regulating temperature work operation in the start operation, the air themperature of conditioned space is higher, when requiring air conditioner to provide big cold to make the Air Conditioning fast cooling, the aerial condenser that allows to be provided with in indoor condenser and the regenerator Air Conditioning that circulates simultaneously, the evaporation cold that impels air conditioner to make full use of refrigerant reduces the air themperature of conditioned space fast.Behind air conditioner start operation certain hour, when the air themperature of conditioned space reaches the room temperature of user's setting gradually, the air conditioner that utilizes cold-storage method for regulating temperature work operation impels regenerator to enter process of cool under an adiabatic relatively environment by cutting off the method for the ventilating air of the aerial condenser of setting in the regenerator.
Invent a kind of cold-accumulating air conditioner according to the method for above-mentioned cold-storage temperature adjustment.In air conditioner, increase the regenerator that can save cold is set.In the regenerator, splendid attire but loss of heat solidifies under the evaporating temperature of air conditioner refrigeration medium liquid or gluey cool storage medium, be provided with the heat-exchanging component of heat conduction, also be provided with on the heat-exchanging component in cool storage medium to the evaporation tubes of the heat absorption evaporation of flowing is provided through the refrigerant after the liquefaction of processes such as air conditioner compression, cooling, throttling, cooling.The refrigerant evaporation tubes of regenerator inserts in the refrigerant flow cycle of air conditioner by the refrigerant entrance point of refrigerant conduit at indoor condenser condenses pipe.After cold-accumulating air conditioner is realized said structure, in the workflow of air conditioner, send in the evaporation tubes of regenerator by the refrigerant conduit through the refrigerant after the liquefaction of processes such as air conditioner compression, cooling, throttling, cooling, when the refrigerant that has liquefied circulated in the evaporation tubes of regenerator, the heat that obtains the cool storage medium of splendid attire in the regenerator under the conduction of radiating subassembly entered evaporation process.Because the evaporating temperature of refrigerant is lower than the necessary temperature of cool storage medium condensation cured,, both entered process of cool so the liquid or gluey cool storage medium of splendid attire must enter the loss of heat cooling and the process of condensation cured gradually in the regenerator.In process of cool, refrigerant is after finishing evaporation process on the evaporimeter of regenerator, cooled media lines is sent regenerator and inlet chamber inner condenser, continue to carry out cold and hot exchange with the residue cold by the radiating subassembly and the ventilating air on the condenser of condenser, sucked by compressor by the refrigerant conduit then, enter next flow process.
An aerial condenser is set in the regenerator that increases in air conditioner, equally distributed heat-exchanging component constitutes this condenser with the orientation that makes things convenient for circulation of air by one group, and these radiating subassemblies with corresponding being connected of heat-exchanging component of cool storage medium form the joint face of cold and hot exchange.After cold-accumulating air conditioner was realized said structure, in the workflow of air conditioner, when compressor of air conditioner was shut down, refrigerant stopped circulation and stops the evaporation process of absorbing heat.But cold and hot exchange process under the effect of the heat-exchanging component of aerial condenser heat-exchanging component and cool storage medium, takes place with the cool storage medium that has solidified in the regenerator in the Air Conditioning that is involved in by air-conditioning draught fan when the aerial condenser circulation of regenerator.At this moment, the cool storage medium that has solidified in the regenerator begins to enter the heat absorption course of dissolution, and the Air Conditioning of this aerial condenser of flowing through has entered the loss of heat temperature-fall period, has reached the purpose of air conditioner cold-storage temperature adjustment.
On the port of the air channel that the aerial condenser of regenerator constitutes a ventilating air guide plate is set, this guide plate can opened port on the regenerator air channel according to the sealing of different operating state or appropriateness under the effect of air conditioner brakes.The air channel that the aerial condenser of regenerator constitutes is arranged on the air channel of air-conditioning draught fan, and constitutes the tributary, an air channel on the air-conditioning draught fan air channel when the ventilating air guide plate is opened port on the aerial condenser air channel of regenerator.After cold-accumulating air conditioner is realized said structure, at the initial stage of air conditioner start operation, the air themperature of conditioned space is higher, when requiring air conditioner to provide big cold to make the Air Conditioning fast cooling, be arranged on the air channel that the air guide plate in the cold-accumulating air conditioner is opened regenerator, make the Air Conditioning that in the condenser of regenerator, obtained cold cooling and cooling air from indoor condenser, together be rolled in the conditioned space by air-conditioning draught fan, the evaporation cold that impels cold-accumulating air conditioner to make full use of refrigerant reduces the air themperature of conditioned space fast.Behind cold-accumulating air conditioner start operation certain hour, when the air themperature of conditioned space reaches the room temperature of user's setting gradually, air channel guide plate in the cold-accumulating air conditioner is under the effect of guide plate brakes, air channel sealing with regenerator, stopped the circulation of air in the regenerator air channel, make the cooling circulation of air that only keeps in the air channel of air-conditioning draught fan from indoor condenser, remain in the appropriate air themperature scope to keep conditioned space.Simultaneously, after the air in the regenerator air channel stops circulation, cool storage medium in the regenerator stops the heat transfer process with ventilating air, makes cool storage medium in the regenerator enter the loss of heat cooling and the process of cool of condensation cured gradually under an adiabatic relatively condition.After regenerator is finished process of cool, compressor of air conditioner quits work, air channel guide plate in the air conditioner is under the effect of guide plate brakes, be opened again, allow in the regenerator air channel, to circulate again, and make air conditioner can after compressor of air conditioner is out of service, still keep the certain hour thermoregulatory effect through Air Conditioning after the temperature adjustment of regenerator cold-storage.Because the solution temperature of the cool storage medium that has solidified in the regenerator is lower, causes the air themperature of carrying out cold and hot exchange with it also lower.Therefore, air channel guide plate in the air conditioner is the appropriateness air channel of opening regenerator as required, make the Air Conditioning of appropriate flow enter into the condensation of air regenerator, and from the aerial condenser of regenerator flow through can also be before entering conditioned space than cold air, with mix mutually from the Air Conditioning of indoor condenser and obtain thermoregulation effect after be admitted to conditioned space jointly.
After the cool storage medium that has solidified in the regenerator absorbed heat dissolving fully, the Air Conditioning in the regenerator air channel of flowing through stopped the loss of heat temperature-fall period, and the conditioned space temperature also rises thereupon gradually.When the temperature sensor senses that is provided with in the air-conditioner arrived the maximum temperature value that is provided with by the user, temperature sensor generation braking action made compressor of air conditioner restart, and air conditioner restarts an aforesaid heat exchange temperature adjustment circulation.
For the cool storage medium that cooperates regenerator is saved cold, accessories such as the compressor that uses in this cold-accumulating air conditioner, capillary, the evaporating temperature that can be enough to make it corresponding suitable refrigerant when its work is lower than the necessary temperature of cool storage medium condensation cured.

The specific embodiment
In Fig. 1, embodiments of the invention increase in air conditioner and are provided with one and can save cold, prolong the compressor start start regenerator 1 of blanking time.But in regenerator 1 splendid attire the liquid or gluey cool storage medium 3 that solidifies of loss of heat, and the heat-exchanging component 4 that has been provided with the heat conduction; Be provided with on the heat-exchanging component 4 in cool storage medium 3 to the evaporation tubes 2 of the heat absorption evaporation of flowing is provided by the refrigerant after the liquefaction of processes such as air conditioner compression, cooling, throttling.The refrigerant evaporation tubes 2 of regenerator inserts in the refrigerant flow cycle of air conditioner by the refrigerant entrance point of refrigerant conduit 15 at indoor heat exchange condensers 10 condenser pipes 12.An aerial condenser 5 is set in regenerator 1, equally distributed radiating subassembly constitutes condenser 5 with the orientation that makes things convenient for circulation of air by one group, and the heat-exchanging component 4 corresponding joint faces 6 that are connected and form cold and hot exchange of these radiating subassemblies and cool storage medium.At the air outlet slit end of the aerial condenser 5 of regenerator the air channel 14 of an Air Conditioning circulation is set, the main air duct 8 of this air channel 14 and the air channel 13 access cold-accumulating air conditioners parallel with one another of indoor condenser.In the regenerator air channel 14 with the interface of air conditioner main air duct 8, a ventilating air guide plate 9 is set, and this guide plate can seal or open the outlet of regenerator air channel on main air duct according to the different operating state of air conditioner under the effect of air-conditioning brakes.For the cool storage medium 3 that cooperates regenerator is saved cold, at this accessories such as the compressor 16 that uses in the air conditioner of cold-storage method for regulating temperature, capillary 18 that utilize, when its work, can make with the evaporating temperature of the suitable refrigerant of correspondence be lower than the necessary temperature of cool storage medium 3 condensation cured.
Following three kinds of workflows appear in air conditioner when utilizing method operation work of the present invention:
The firstth, force operation work under the cold state.At the initial stage of cold-accumulating air conditioner start operation, the air themperature of conditioned space is higher, when requiring air conditioner to provide big cold to make the Air Conditioning fast cooling, is arranged on the outlet that the interior air channel guide plate 9 of cold-accumulating air conditioner is opened regenerator air channel 14.And refrigerant 3 compressed machine 16 compressions in the cold-accumulating air conditioner, outdoor condenser 17 coolings are admitted to the evaporation tubes 2 in the air conditioner regenerator 1 after the liquefaction of processes such as capillary 18 throttlings, decompression, cooling.When the refrigerant that has liquefied circulated in the evaporation tubes 2 of regenerator, the heat that obtains the cool storage medium 3 of splendid attire in the regenerator 1 under the conduction of radiating subassembly 4 entered evaporation process.In the evaporation process of refrigerant, cold and hot exchange is carried out in cool storage medium 3 losss of heat cooling back under the radiating subassembly effect on the condenser 5 of its radiating subassembly 4 and regenerator with from the Air Conditioning of these these condenser 5 circulations, thereby the Air Conditioning that makes circulation obtains cold and lowers the temperature, and is involved in the main air duct 8 of cold-accumulating air conditioner by air-conditioning draught fan 7 thereupon.Refrigerant is then after finishing evaporation process on the evaporation tubes 2 of regenerator, cooled media lines 15 is sent the condenser pipe 12 of regenerator and inlet chamber inner condenser 10, continue to carry out cold and hot exchange with the residue cold by the radiating subassembly 11 of condenser and the ventilating air on the condenser, sucked by compressor 16 by the refrigerant conduit then, enter next flow process.Indoor condenser 10 chilled Air Conditioning then also be involved in the main air duct 8 of cold-accumulating air conditioner by air-conditioning draught fan 7 by condenser air concentrator 13 and with mix the back from the Air Conditioning in regenerator air channel 14 mutually and sent into conditioned space simultaneously.Because cold-accumulating air conditioner operation work under this state, regenerator 1 and indoor condenser 10 provide cold for Air Conditioning simultaneously, both the refrigerating capacity with this machine maximum was that Air Conditioning provides cold, therefore, can reach the purpose of the quickest reduction Air Conditioning temperature.
The secondth, operation work under the cold-storage state.Behind cold-accumulating air conditioner start operation certain hour, when the air themperature of conditioned space reaches the room temperature of user's setting gradually, air channel guide plate 9 in the cold-accumulating air conditioner is under the effect of guide plate brakes, air channel 14 sealings with regenerator, stopped the circulation of air in the regenerator air channel 14, and 8 reservations of main air duct are from the Air Conditioning circulation of indoor condenser air concentrator 13, to ensure the temperature adjustment requirement of conditioned space.Simultaneously, after the air in the regenerator air channel 14 stopped circulation, the cool storage medium 3 in the regenerator 1 stopped the heat transfer process with ventilating air, and the cool storage medium in the regenerator is remained in the adiabatic relatively environment.And the refrigerant in the regenerator evaporation tubes 2 still continues its evaporation process, and because the evaporating temperature of refrigerant is lower than the necessary temperature of cool storage medium 3 condensation cured, so the liquid or gluey cool storage medium 3 of splendid attire must enter the loss of heat cooling and the process of condensation cured gradually in the regenerator 1, has both entered operation work under the cold-storage state.Because cold-accumulating air conditioner operation work under the cold-storage state, only keep Air Conditioning circulation in the main air duct 8 from indoor condenser air concentrator 13, therefore under this state of cold-accumulating air conditioner during operation work, can only keep the conditioned space temperature can be constant in certain limit.
The 3rd is operation work under the state of cold-storage temperature adjustment.When the cool storage medium 3 of regenerator is near completion the condensation cured process, the loss of heat amount of cool storage medium 3 also constantly descends thereupon, the refrigerant that can not get enough evaporation heats is inevitable along refrigerant conduit 15, the heat absorption evaporation process is extended in the condenser 10 of air conditioner, strengthened by the heat exchange amount of this condenser radiating subassembly 11 with the ventilating air that is involved in by air-conditioning draught fan, the cooling extent of ventilating air is constantly increased, when the temperature of ventilating air drops to when being enough to make the temperature sensor generation braking action that is provided with in the air conditioner, compressor of air conditioner 16 is out of service immediately.When compressor of air conditioner 16 was shut down, refrigerant stopped circulation and stops the evaporation process of absorbing heat, but the cool storage medium 3 that has solidified in the regenerator 1 begins to enter the heat absorption course of dissolution.In the heat absorption course of dissolution, the air channel guide plate 9 in the cold-accumulating air conditioner is opened the air channel 14 of regenerator under the effect of guide plate brakes, allows Air Conditioning circulate in regenerator air channel 14 again.After the Air Conditioning that in regenerator air channel 14, goes into circulation, be arranged on 5 of condensers on the air channel thereupon under the effect of its radiating subassembly and cool storage medium radiating subassembly 4 with regenerator 1 in cool storage medium 3 carry out cold and hot exchange, make the Air Conditioning in the regenerator air channel 14 of flowing through after compressor of air conditioner 16 is out of service, still keep certain hour loss of heat temperature-fall period.In this loss of heat temperature-fall period and since solidified in the regenerator 1 the solution temperature of cool storage medium 3 lower, cause the air themperature of carrying out cold and hot exchange with it also lower.For reaching best temperature adjustment purpose, air channel guide plate 9 in the air conditioner is the appropriateness air channel 14 of opening regenerator as required, make from regenerator enter the main air duct 8 of air conditioner than the cold air appropriateness, and with mix mutually from the Air Conditioning of indoor condenser air concentrator 13 after be admitted to conditioned space jointly.
After the cool storage medium 3 that has solidified in the regenerator 1 absorbed heat dissolving fully, the Air Conditioning in the regenerator air channel 14 of flowing through stopped the loss of heat temperature-fall period, and the conditioned space temperature also rises thereupon gradually.When the temperature sensor senses that is provided with in the air-conditioner arrived the maximum temperature value that is provided with by the user, temperature sensor generation braking action made compressor of air conditioner restart, and air conditioner restarts an aforesaid heat exchange temperature adjustment circulation.
Fig. 2, embodiment illustrated in fig. 3 in, in air conditioner, increase the regenerator 1 that can save cold be set.In regenerator, but not only splendid attire loss of heat solidifies under the evaporating temperature of air conditioner refrigeration medium liquid or gluey cool storage medium 3, but also be provided with the heat-exchanging component 4 of heat conduction.For the evaporation tubes 2 that the heat absorption evaporation of flowing is provided through the refrigerant after the liquefaction of processes such as air conditioner compression, cooling, throttling, cooling is arranged on the heat-exchanging component 4 in the cool storage medium 3.The refrigerant evaporation tubes 2 of regenerator inserts in the refrigerant flow cycle of air conditioner by the refrigerant entrance point of refrigerant conduit at indoor heat exchange condensers 10 condenser pipes 12.An aerial condenser 5 is set in the regenerator 1 that increases in air conditioner, equally distributed heat-exchanging component 19 constitutes condenser 5 with the orientation that makes things convenient for circulation of air by one group, and the heat-exchanging component 4 corresponding joint faces 6 that are connected and form cold and hot exchange of these radiating subassemblies 19 and cool storage medium.On the air port of the aerial condenser 5 of regenerator 1, a ventilating air guide plate 9 is set, this guide plate 9 can be opened the aerial condenser 5 of regenerator 1 according to the sealing of different operating state or the appropriateness of air conditioner under the effect of air-conditioning brakes air channel port.The air channel that the condenser 5 of regenerator 1 constitutes is arranged on the air channel of air-conditioning draught fan 7, and constitutes the tributary, an air channel on the air-conditioning draught fan air channel when ventilating air guide plate 9 is opened port on aerial condenser 5 air channels of regenerator 1.
