Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
Fig. 1 is a schematic structural diagram of a dual refrigeration type air conditioner provided in an embodiment of the present disclosure.
As shown in fig. 1, an embodiment of the present disclosure provides a dual refrigeration type air conditioner, including a refrigerant heat exchange system and an adsorption refrigeration system; the refrigerant heat exchange system can be a single-cooling type refrigerant heat exchange system which can be used for refrigerating and dehumidifying the indoor environment, and can also be a cooling and heating type refrigerant heat exchange system which can be used for refrigerating, dehumidifying and heating the indoor environment. The adsorption refrigeration system may be used to provide refrigeration to the indoor environment when it is operating in an adsorption refrigeration mode.
In some optional embodiments, taking a cooling and heating type refrigerant heat exchange system as an example, the refrigerant heat exchange system mainly includes an indoor heat exchanger 11, an outdoor heat exchanger 12, a compressor 13, a throttling device 14, and other components; the indoor heat exchanger 11, the outdoor heat exchanger 12, the throttling device 14 and the compressor 13 are connected through refrigerant pipelines to form a refrigerant circulation loop, and the refrigerant flows along the flow direction set by different operation modes through the refrigerant circulation loop, so that the functions of the different operation modes are realized.
Here, the dual cooling type air conditioner includes an indoor unit and an outdoor unit, wherein indoor heat exchange is provided to the indoor unit, and an indoor fan for driving indoor air to exchange heat with the indoor heat exchanger 11 is further provided in the indoor unit; the outdoor heat exchanger 12, the compressor 13, and the like are provided in an outdoor unit, and an outdoor fan for exchanging heat between outdoor air and the outdoor heat exchanger 12 is also disposed in the outdoor unit, wherein the outdoor heat exchanger 12 is provided on an air intake side of the outdoor fan.
In an embodiment, the operation modes of the refrigerant heat exchange system of the dual-refrigeration type air conditioner comprise a refrigerant refrigeration mode, a refrigerant dehumidification mode, a refrigerant heating mode and the like, wherein the refrigerant refrigeration mode is generally applied to a high-temperature working condition in summer and used for reducing the indoor environment temperature; the refrigerant dehumidification mode is also generally used for the high-temperature and high-humidity working condition in summer and is used for reducing the indoor environment humidity; the refrigerant heating mode is generally applied to the low-temperature working condition in winter and is used for increasing the indoor environment temperature.
When the refrigerant heat exchange system operates in the refrigerant refrigeration mode, the set refrigerant flow direction is that a high-temperature refrigerant discharged by the compressor 13 firstly flows through the outdoor heat exchanger 12 to exchange heat with the outdoor environment, then flows into the indoor heat exchanger 11 to exchange heat with the indoor environment, and finally the refrigerant flows back to the compressor 13 to be compressed again; in this process, the refrigerant flowing through the outdoor heat exchanger 12 emits heat to the outdoor environment, the refrigerant flowing through the indoor heat exchanger 11 absorbs heat from the indoor environment, and the heat in the room can be continuously discharged to the outdoor environment through the circulating flow of the refrigerant in the refrigerant circulation circuit, so that the refrigeration purpose of reducing the temperature of the indoor environment can be achieved.
The difference is that the temperature and pressure of the refrigerant flowing into the indoor heat exchanger 11 can be lower by adjusting some operation parameters when the air conditioner operates in the refrigerant dehumidification mode, such as reducing the flow opening degree of the throttling device 14, so that the indoor heat exchanger 11 can reach lower temperature along with the heat absorption evaporation of the refrigerant, and thus, when the surface temperature of the indoor heat exchanger 11 is lower than the dew point temperature of the current working condition, the water vapor in the indoor air flowing through the indoor heat exchanger 11 can be condensed on the indoor heat exchanger 11, thereby achieving the purpose of reducing the humidity of the indoor air.
The refrigerant flow direction set during the operation of the refrigerant heating mode indicates that a high-temperature refrigerant discharged by the compressor 13 firstly flows through the indoor heat exchanger 11 to exchange heat with the outdoor environment, then flows into the outdoor heat exchanger 12 to exchange heat with the indoor environment, and finally flows back to the compressor 13 to be compressed again; in this process, the refrigerant flowing through the indoor heat exchanger 11 emits heat to the indoor environment, the refrigerant flowing through the outdoor heat exchanger 12 absorbs heat from the outdoor environment, and the outdoor heat can be continuously released to the indoor environment through the circulating flow of the refrigerant in the refrigerant circulation circuit, so that the heating purpose of increasing the temperature of the indoor environment can be achieved.
In some optional embodiments, each component of the refrigerant heat exchange system is assembled by using a connection structure of an existing refrigerant heat exchange system in the prior art, which is not described herein again.
In some optional embodiments, the dual refrigeration type air conditioner may be provided with only one adsorption refrigeration system, or may be provided with an adsorption refrigeration system group, and the adsorption refrigeration system group includes two or more adsorption refrigeration systems.
Taking one of the adsorption refrigeration systems as an example, the adsorption refrigeration system includes an adsorption part 21 and an evaporation part 22, wherein the adsorption part 21 is disposed at the outdoor heat exchanger 12 of the refrigerant heat exchange system, and is filled with an adsorbent, which is used for absorbing heat in a desorption cold storage stage and then releasing an adsorption medium, and for adsorbing the adsorption medium and releasing heat in an adsorption refrigeration stage; the evaporation part 22 is disposed at the indoor side, and is used for storing the liquid adsorption medium from the adsorption part 21 in the desorption cold accumulation stage, and absorbing heat from the indoor environment in the adsorption refrigeration stage and delivering the vaporized adsorption medium to the adsorption part 21.
In some embodiments, the adsorption part 21 is disposed between the outdoor fan and the outdoor heat exchanger 12. Here, since the outdoor heat exchanger 12 is disposed on the air inlet side of the outdoor fan, under the driving action of the outdoor fan, the heat dissipated by the outdoor heat exchanger 12 can firstly flow through the adsorption part 21 sandwiched between the outdoor fan and the outdoor heat exchanger 12, so that the adsorption part 21 can absorb a large amount of heat for desorption cold accumulation in the desorption cold accumulation stage; meanwhile, the adsorption part 21 is also positioned at the air inlet side of the outdoor fan, so that the heat released by the adsorption part 21 can be dissipated to the outdoor environment by using the driving action of the outdoor fan in the adsorption refrigeration stage.
Optionally, the outdoor heat exchanger 12 is a plate-shaped structure, and the cross-sectional profile of the outdoor heat exchanger is in a half-hoop outdoor fan form; therefore, in order to improve the heat exchange effect between the adsorption part 21 and the outdoor heat exchanger 12, in this embodiment, the overall shape of the adsorption part 21 is adapted to the outdoor heat exchanger 12, and is also designed to be in a form of half-encircling the outdoor fan, and the adsorption part is attached to the outdoor heat exchanger 12, so that the heat exchange area between the adsorption part 21 and the outdoor heat exchanger 12 is effectively increased, and the waste heat utilization efficiency of the outdoor heat exchanger 12 is improved.
Here, for the adsorption refrigeration system group, in order to enable the adsorption portions 21 of the plurality of adsorption refrigeration systems to absorb heat with the outdoor heat exchanger 12, and avoid the situation that the heat absorption is too small due to deviation of the adsorption portions 21 of the individual adsorption refrigeration systems from the outdoor heat exchanger 12, the adsorption portions 21 of the plurality of adsorption refrigeration systems of the adsorption refrigeration system group are arranged side by side, optionally, the adsorption portions 21 of the plurality of adsorption refrigeration systems are arranged side by side along the transverse direction or the longitudinal direction of the outdoor heat exchanger 12, and the adsorption portions 21 are designed into shapes matched with the positions of the corresponding outdoor heat exchangers 12, so as to ensure the heat exchange efficiency of the adsorption refrigeration system group and the outdoor heat exchanger 12.
Alternatively, an adsorption medium transfer flow path is also formed between adjacent adsorption sections 21; in this way, in the desorption cold accumulation and adsorption cold accumulation stages, the gaseous adsorption medium can flow among the plurality of adsorption portions 21, thereby improving the desorption cold accumulation effect and the adsorption refrigeration effect of the adsorption refrigeration system set as a whole.
Optionally, the evaporation part 22 is of a plate-fin structure, and the plate-fin structure can effectively improve the heat exchange effect between the adsorption medium in the evaporation part 22 and the indoor environment in the desorption cold storage stage, and enhance the heat absorption and refrigeration capacity; meanwhile, a flow path through which the adsorbent flows is formed inside the evaporation unit 22, and the flow path of the adsorbent communicates with the adsorbent transport flow path.
In some optional embodiments, the indoor heat exchanger 11 is in a structural form that the longitudinal section is in a broken line shape and semi-encircles the indoor fan; therefore, in order to improve the heat exchange effect between the evaporation portion 22 and the indoor environment, in this embodiment, the overall shape of the evaporation portion 22 is adapted to the indoor heat exchanger 11, and is also designed to be in a form of a half-encircling indoor fan, and the evaporation portion is attached to the indoor heat exchanger 11, so as to increase the heat exchange area between the evaporation portion 22 and the airflow flowing through the indoor unit, and improve the heat absorption and cooling capacity.
Here, in the adsorption refrigeration system group, in order to enable the evaporation units 22 of the plurality of adsorption refrigeration systems to uniformly absorb heat from the indoor environment, the evaporation units 22 of the plurality of adsorption refrigeration systems are also arranged side by side; alternatively, the evaporation parts 22 of a plurality of adsorption refrigeration systems are arranged side by side along the transverse direction or the longitudinal direction of the indoor heat exchanger 11, and the evaporation parts 22 are designed to be matched with the parts of the indoor heat exchangers 11 corresponding to the evaporation parts.
Alternatively, an adsorption medium transfer flow path is also configured between adjacent evaporation portions 22; in this way, in the desorption cold accumulation and adsorption cold accumulation stages, the liquid and gaseous adsorption media can flow among the plurality of evaporation portions 22, thereby improving the desorption cold accumulation effect and the adsorption refrigeration effect of the adsorption refrigeration system set as a whole.
In addition, the adsorption refrigeration system further includes an intermediate heat dissipation portion 23; the middle heat dissipation part 23 is disposed on the adsorption medium conveying flow path, and is configured to receive the gaseous adsorption medium conveyed by the adsorption part 21 in the desorption cold storage stage, dissipate heat and condense the gaseous adsorption medium, so as to liquefy at least a portion of the gaseous adsorption medium, and continuously convey the liquefied adsorption medium to the evaporation part 22 for storage.
Here, the intermediate heat radiating portion 23 is provided outside the room, and it performs heat radiation and condensation on the adsorption medium by heat exchange with the outdoor environment; when the refrigerant heat exchange system operates in the refrigerant cooling mode, the outdoor heat exchanger 12 discharges heat to the outside, and the temperature of the adsorption portion 21 is generally higher than the outdoor environment temperature, so that the gaseous adsorption medium released by the adsorption portion 21 affected by the high-temperature heat flows into the intermediate heat dissipation portion 23, and the heat is dissipated to the outdoor environment, so that at least part of the gaseous adsorption medium is condensed into liquid again.
Optionally, the intermediate heat dissipation portion 23 is a horizontal flow type heat sink.
In some embodiments, the intermediate heat dissipation part 23 is disposed on a back plate, a side plate, or a bottom plate of the outdoor unit of the refrigerant heat exchange system, and is disposed away from the air outlet of the outdoor unit, so as to prevent high-temperature air discharged from the outdoor unit from affecting the heat dissipation effect of the intermediate heat dissipation part 23.
Preferably, the intermediate heat dissipation part 23 is disposed at a bottom plate, and in this arrangement, the outdoor unit can shield the intermediate heat dissipation part 23 from sunlight, so as to provide a more suitable heat dissipation temperature environment for the intermediate heat dissipation part 23.
Or, because the back plate of the outdoor unit is provided with the air inlet, the middle heat dissipation part 23 can also be arranged close to the air inlet, so that the driving action of the outdoor fan is utilized to accelerate the flow of the ambient air flow around the middle heat dissipation part 23, and the heat dissipation effect is improved.
In the present embodiment, an adsorption medium transport flow path is configured between the adsorption part 21 and the evaporation part 22, and the adsorption medium can flow between the adsorption part 21, the intermediate heat dissipation part 23, and the evaporation part 22 through the adsorption medium transport flow path.
Here, the adsorption medium delivery flow path includes a desorption flow path and an adsorption flow path, wherein the desorption flow path is a flow path for the adsorption cold storage stage adsorption medium delivery, and the adsorption flow path is a flow rate for the adsorption cold storage stage adsorption medium delivery.
In the desorption flow path, the adsorption portion 21, the intermediate heat dissipation portion 23, and the evaporation portion 22 are connected in series in this order, so that the adsorption medium flows out of the adsorption portion 21 in the desorption cold storage stage, then sequentially enters the intermediate heat dissipation portion 23 and the evaporation portion 22, and finally is stored in the evaporation portion 22 in a liquid state.
Optionally, a one-way valve is arranged on the desorption flow path, and the one-way valve limits that the adsorption medium can be conveyed only according to the flow direction of the adsorption part 21 → the middle heat dissipation part 23 → the evaporation part 22; here, the check valve may be provided in the flow path between the adsorption part 21 and the intermediate heat dissipation part 23, or may be provided in the flow path between the intermediate heat dissipation part 23 and the evaporation part 22.
In the adsorption flow path, the evaporation unit 22 and the adsorption unit 21 are connected in series, so that the adsorption medium flows out of the evaporation unit 22 in the adsorption refrigeration stage, then enters the adsorption unit 21 through the adsorption flow path, and is adsorbed again by the adsorbent in the adsorption unit 21.
Optionally, a check valve is disposed on the adsorption flow path, and the check valve limits the adsorption medium to be transported only in the flow direction of "evaporation portion 22 → adsorption portion 21".
Alternatively, the desorption flow path is set as the main flow path, and the adsorption flow path is set in parallel with the intermediate heat dissipation portion 23, so that the non-parallel flow path section of the desorption flow path close to the adsorption portion 21 can also be used for conveying the adsorption medium in the adsorption refrigeration stage.
In this embodiment, the adsorption refrigeration system further includes a control valve 24 disposed on the adsorption medium transport flow path for controlling the on-off state and flow rate of the adsorption medium transport flow path. Here, the control valve 24 is provided in the non-parallel flow path section of the desorption flow path near the adsorption section 21 in the above embodiment, so that the flow rate on-off control in two stages of desorption cold accumulation and adsorption refrigeration can be realized by only the single control valve 24.
Alternatively, a control valve 24 may be disposed on each of the desorption flow path and the adsorption flow path, so that the on-off state and the flow rate of the corresponding flow path are controlled by the respective control valves 24.
The following describes the working mode of the adsorption refrigeration system and the refrigerant heat exchange system in the embodiment of the present disclosure:
in this embodiment, the operation modes of the adsorption refrigeration system mainly include a desorption cold accumulation mode and an adsorption refrigeration mode, wherein the desorption cold accumulation mode corresponds to the desorption cold accumulation stage in the previous embodiments and is mainly used for accumulating "cold"; the adsorption refrigeration mode corresponds to the adsorption refrigeration stage in the previous embodiment, and is mainly used for releasing cold energy accumulated in the desorption cold storage stage, so that refrigeration and temperature reduction of the indoor side where the adsorption refrigeration mode is located are realized.
Here, the desorption and cold accumulation mode of the adsorption refrigeration system is operated on the premise that the refrigerant heat exchange system operates in the refrigerant refrigeration mode or the refrigerant dehumidification mode. Here, when the refrigerant heat exchange system operates in the refrigerant cooling mode, the exterior heat exchanger 12 releases heat, the heat is transferred to the adsorption portion 21, the adsorption medium adsorbed by the adsorbent in the adsorption portion 21 absorbs heat and is desorbed into a gaseous adsorption medium, and then the gaseous adsorption medium enters the intermediate heat-radiating portion 23 through the desorption flow path to be condensed, and the condensed liquid adsorption medium enters the evaporation portion 22 as "cold" accumulated therein.
The adsorption refrigeration system operates in the adsorption refrigeration mode on the premise that the refrigerant heat exchange system does not operate in the refrigerant refrigeration mode or the refrigerant dehumidification mode. Here, when the refrigerant heat exchange system is not operated in the refrigerant cooling mode or the refrigerant dehumidification mode, the exterior heat exchanger 12 is not operated and does not radiate heat to the outside, so that the temperature of the adsorption part 21 is lower than that when the exterior heat exchanger 12 radiates heat, so that the adsorbent in the adsorption part 21 starts to adsorb the adsorption medium again, the liquid adsorption medium in the evaporation part 22 starts to absorb heat and evaporate into a gaseous adsorption medium under the common influence of various factors such as the concentration, pressure and indoor environment temperature of the adsorption medium, and is returned to the adsorption part 21 through the adsorption flow path, in which process the adsorption medium absorbs heat from the indoor environment, and releases the heat to the outdoor environment where the adsorption part 21 is located after the adsorption medium is re-adsorbed by the adsorbent, therefore, the adsorption refrigeration and temperature reduction of the indoor environment can be realized by the flow of the adsorption medium in the reverse direction of the desorption cold accumulation stage.
Fig. 2 is a schematic flowchart of a control method for a dual refrigeration type air conditioner according to an embodiment of the present disclosure.
As shown in fig. 2, a control method for a dual refrigeration type air conditioner is provided in the embodiment of the present disclosure, and optionally, the control method may be applied to the dual refrigeration type air conditioner as shown in the embodiment of fig. 1; the control method can be used for solving the problem that the refrigeration work of the air conditioner is not realized by two refrigeration technologies of refrigerant refrigeration and adsorption refrigeration in the prior art; in an embodiment, the main flow steps of the control method include:
s201, when the double-refrigeration type air conditioner is started, controlling an adsorption refrigeration system set to enter an adsorption refrigeration mode;
in this embodiment, when the adsorption refrigeration system set operates in the adsorption refrigeration mode, the liquid adsorption medium in the evaporation unit is accumulated during the previous operation of the dual refrigeration type air conditioner in the refrigerant refrigeration mode or the previous operation of the dual refrigeration type air conditioner in the refrigerant refrigeration mode.
When the refrigerant heat exchange system operates in a refrigerant refrigeration mode, the adsorption refrigeration system set is in a desorption cold accumulation mode; the outdoor heat exchanger discharges heat, so that the ambient temperature of the outdoor heat exchanger rises, the adsorption medium in the adsorption part of the adsorption refrigeration system arranged close to the outdoor heat exchanger absorbs the heat and then is separated from the adsorbent, desorption is realized, the desorbed adsorption medium flows to the middle heat exchange part along the adsorption medium conveying flow path, the temperature of the middle heat exchange part is lower than that of the outdoor heat exchanger, and therefore the adsorption medium releases heat and condenses and continues to flow into the evaporation part on the indoor side along the adsorption medium conveying flow path, and cold accumulation is realized. And after the double-refrigeration type air conditioner stops operating the refrigerant refrigeration mode, controlling the adsorption refrigeration system to exit the desorption cold storage mode and controlling and blocking the adsorption medium conveying flow path, so that the adsorption medium cannot flow back to the adsorption part.
Therefore, the adsorption medium conveying flow path can be conducted under the condition that the adsorption refrigeration system group needs to operate in the adsorption refrigeration mode; when the adsorption refrigeration system set operates in the adsorption refrigeration mode, the refrigerant heat exchange system is in a standby state or a stop state, and the outdoor heat exchanger of the refrigerant heat exchange system does not discharge heat outwards, so that the ambient temperature of the outdoor heat exchanger is close to the ambient temperature of the outdoor heat exchanger after the dual-refrigeration type air conditioner stops operating in the refrigerant refrigeration mode during desorption cold accumulation, the adsorption part can adsorb the adsorption medium again, and then the liquid adsorption medium in the evaporation part absorbs heat and evaporates under the action of adsorption pressure, thereby achieving the purpose of adsorption refrigeration.
Optionally, a control valve is arranged on an adsorption medium conveying flow path of the adsorption refrigeration system, and the control valve can be used for controlling the on-off state of the adsorption medium flow path and adjusting the flow rate; thus, in the present embodiment, the operation of conducting or blocking the adsorption medium transport flow path can be achieved by the control valve.
S202, acquiring the variable temperature rate of the indoor environment temperature;
in some alternative embodiments, the indoor unit of the air conditioner is provided with a temperature sensor that can be used to detect the real-time temperature of the indoor environment inside the room. Therefore, the indoor ambient temperature in step S202 can be detected by the temperature sensor.
Here, the dual-refrigeration air conditioner can store the real-time temperature of the indoor environment detected by the temperature sensor as historical data, so that the indoor environment temperature corresponding to different running moments of the dual-refrigeration air conditioner can be called at any time according to needs.
For example, the interval of the real-time temperature of the indoor environment detected by the temperature sensor is 1min, and within a time period of 3 minutes, the indoor environment temperature detected at the initial time of the time period is 29 ℃, the indoor environment temperature detected at the end time of the time period is 26 ℃, then the temperature change rate of the indoor environment within the time period is calculated by the following formula:
△Tr/t＝(29-26)÷3＝1℃/min；
in the above formula,. DELTA.TrAnd/t is the temperature change rate of the indoor environment temperature.
And S203, controlling to start the refrigerant heat exchange system when the temperature change rate of the indoor environment temperature does not meet the preset rate requirement.
In some optional embodiments, the preset rate condition includes:
△Tr/t≥△Tthreshold value/t；
Wherein, Delta TrT is the temperature change rate of the indoor environment temperature, T is unit time, and delta TrIs the variation of the indoor ambient temperature; delta TThreshold valueAnd/t is a preset temperature change rate threshold value.
Optionally, the preset temperature change rate threshold is 0.2-0.5 ℃/min.
In this embodiment, the temperature change rate threshold is a critical value used for representing that the temperature change rate of the current indoor environment can meet the cooling requirement; under the condition that the temperature change rate of the indoor environment temperature is greater than or equal to the temperature change rate threshold value, the refrigeration effect of the adsorption refrigeration mode of the double-refrigeration type air conditioner is better, the temperature reduction rate is better, and the temperature reduction requirement can be met; and under the condition that the temperature change rate of the indoor environment temperature is smaller than the temperature change rate threshold value, the adsorption refrigeration effect of the double-refrigeration type air conditioner is low, the temperature reduction rate is poor, and the temperature reduction requirement cannot be met.
Therefore, in this embodiment, by comparing the temperature change rate of the indoor environment temperature obtained in real time with the temperature change rate threshold value in the preset rate condition, the refrigerant heat exchange system is controlled to be started to perform refrigeration under the condition that it is determined that the refrigeration effect of the adsorption refrigeration mode of the current dual-refrigeration air conditioner is poor, so as to meet the current refrigeration requirement and ensure the use experience of the user on the air conditioner product.
In some optional embodiments, the refrigeration parameter of the refrigerant heat exchange system activated in step S203 is determined according to a temperature change rate of the indoor ambient temperature.
Here, the temperature change rate of the indoor environment temperature is a temperature change condition of the indoor environment when the adsorption refrigeration mode is operated, and therefore, in the case that the temperature change rate of the indoor environment temperature does not meet the preset rate requirement in the previous embodiment, it is necessary to determine a difference between the temperature change rate and a temperature change rate threshold in the preset rate condition according to the temperature change rate of the current indoor environment temperature, and further adjust the refrigeration parameter of the subsequently-activated refrigerant heat exchange system, so that the temperature change rate of the indoor environment temperature is at least not lower than the temperature change rate threshold when the refrigerant heat exchange system operates the refrigerant refrigeration mode, thereby ensuring that the refrigerant heat exchange system can improve the refrigeration capacity of the dual-refrigeration air conditioner, and improving the refrigeration efficiency of the indoor environment.
Optionally, determining a refrigeration parameter of the refrigerant heat exchange system according to the temperature change rate of the indoor environment temperature includes: and matching the preset incidence relation to obtain the refrigeration parameters of the corresponding refrigerant heat exchange system according to the temperature change rate of the indoor environment temperature.
Here, the preset incidence relation includes a corresponding relation between one or more temperature change rates of the indoor environment temperature and refrigeration parameters of the refrigerant heat exchange system; the temperature change rate of the indoor environment and the refrigeration efficiency corresponding to the refrigerant parameter are in a negative correlation relationship, that is, the lower the temperature change rate of the indoor environment is, the higher the refrigeration efficiency corresponding to the selected refrigerant parameter is, so that the dual-refrigeration air conditioner can be cooled as soon as possible after the refrigerant refrigeration mode is started.
Optionally, the refrigeration parameters include one or more of the following types: the running power of the compressor, the flow opening of the throttling device and the running rotating speed of the inner fan.
In some optional embodiments, the control method for the dual refrigeration type air conditioner of the present disclosure further includes: before controlling the adsorption refrigeration system set to enter an adsorption refrigeration mode, acquiring an initial indoor environment temperature of an indoor side; and determining the starting number of the adsorption refrigeration systems of the adsorption refrigeration system group entering the adsorption refrigeration mode according to the initial indoor environment temperature.
In this embodiment, the number of the adsorption refrigeration systems of the adsorption refrigeration system group that enter the adsorption refrigeration mode is in positive correlation with the refrigeration capacity thereof. Under the condition that the number of the adsorption refrigeration systems is large, the refrigeration capacity of the adsorption refrigeration system set is strong, and the cooling speed of the indoor environment is high; and under the condition that the starting number of the adsorption refrigeration systems is small, the refrigeration capacity of the adsorption refrigeration system group is weak, and the cooling speed of the indoor environment is slow.
Here, the high or low level of the initial indoor ambient temperature can reflect the demand for the cooling capacity of the dual cooling type air conditioner. If the initial indoor environment temperature is high, the requirement on the refrigerating capacity of the double-refrigeration type air conditioner is high, otherwise, the requirement on the refrigerating capacity of the double-refrigeration type air conditioner is low; therefore, the starting number of the adsorption refrigeration systems is determined according to the initial indoor environment temperature, so that the refrigeration capacity of the adsorption refrigeration system set can be matched with the refrigeration demand of the current indoor environment, the problems that the indoor cooling speed is low and the refrigeration demand cannot be met due to the fact that the starting number of the adsorption refrigeration systems is too small are solved, and the problem that the refrigeration capacity of the adsorption refrigeration system set is wasted due to the fact that the starting number of the adsorption refrigeration systems is too large is solved.
Here, the dual refrigeration type air conditioner is also preset with an incidence relation, and the incidence relation comprises a corresponding relation between the initial indoor environment temperature of the indoor side and the starting number of the adsorption refrigeration systems entering the adsorption refrigeration mode; for example, when the initial indoor ambient temperature is 31 ℃, the number of the corresponding adsorption refrigeration systems is 3; and when the initial indoor environment temperature is 27 ℃, the number of the corresponding adsorption refrigeration systems is 1. Therefore, in this correlation, the initial indoor ambient temperature is in a positive correlation with the number of times the adsorption refrigeration system is turned on.
In some optional embodiments, the control method for the dual refrigeration type air conditioner of the present disclosure further includes: and when the temperature change rate of the indoor environment temperature does not meet the preset rate requirement, if the adsorption refrigeration systems in the adsorption refrigeration system group do not reach the maximum starting number, controlling to start one or more unopened adsorption refrigeration systems.
Here, when the temperature change rate of the indoor environment temperature does not meet the preset rate requirement, the number of adsorption refrigeration systems for refrigerating the indoor environment at the same time can be increased by controlling to start one or more adsorption refrigeration systems which are not started, so that the refrigeration effect on the indoor environment can be improved, and compared with the method of directly controlling to start a refrigerant heat exchange system, the power consumption for starting the adsorption refrigeration system to operate in an adsorption refrigeration mode is lower.
In this embodiment, the refrigerant heat exchange system is activated when the number of the adsorption refrigeration systems in the adsorption refrigeration system group reaches the maximum number and still does not satisfy the predetermined rate requirement.
For example, the adsorption refrigeration system group includes 5 adsorption refrigeration systems, and then when step S201 is executed, 2 adsorption refrigeration systems in the adsorption refrigeration system group are controlled to enter an adsorption refrigeration mode; under the condition that the temperature change rate of the indoor environment temperature does not meet the preset rate requirement, controlling to start 1,2 or 3 of the remaining 3 adsorption refrigeration systems to enter an adsorption refrigeration mode so as to enhance the refrigeration efficiency of the adsorption refrigeration systems;
when 5 adsorption refrigeration systems of the adsorption refrigeration system group operate an adsorption refrigeration mode together and last for a first time, obtaining the indoor environment temperature again and judging whether the temperature change rate meets the preset rate requirement; and if not, controlling to start the refrigerant heat exchange system.
Optionally, the first time period is 5min to 10 min.
In some optional embodiments, the control method for the dual refrigeration type air conditioner of the present disclosure further includes: and after the refrigerant heat exchange system is controlled to be started, the adsorption refrigeration system set is controlled to enter a desorption cold accumulation mode.
Therefore, after the refrigerant heat exchange system is started, the adsorption refrigeration system set enters a desorption cold accumulation mode to recycle the desorption cold accumulation mode to carry out cold accumulation, the adsorption refrigeration capacity of the adsorption refrigeration system set is recovered, and the waste heat discharged when the refrigerant heat exchange system is started to operate the refrigerant refrigeration mode can be fully utilized.
Optionally, two or more adsorption refrigeration systems of the adsorption refrigeration system set sequentially enter the desorption cold storage mode. For example, the adsorption refrigeration system group has 3 adsorption refrigeration systems, which are numbered as 1,2 and 3 in sequence; after the refrigerant heat exchange system is started, the adsorption refrigeration system can be controlled to enter a desorption cold accumulation mode according to the sequence of numbers 1,2 and 3, wherein when the adsorption refrigeration system currently running in the desorption cold accumulation mode meets the cold accumulation condition, the adsorption refrigeration system running in the desorption cold accumulation mode with the next sequence number is controlled to run in the desorption cold accumulation mode.
Therefore, at least one adsorption refrigeration system in the adsorption refrigeration system set can meet the cold accumulation condition by sequentially entering the desorption cold accumulation mode so as to ensure the refrigeration capacity when the adsorption refrigeration system set is started again to enter the adsorption refrigeration mode.
In the above embodiment, the control method for a dual refrigeration type air conditioner according to the present disclosure further includes: when the adsorption refrigeration system set enters an adsorption refrigeration mode, controlling an outdoor fan to operate at a first rotating speed; and when the adsorption refrigeration system set enters the desorption cold accumulation mode, the outdoor fan is controlled to operate at a second rotating speed.
In this embodiment, the first rotational speed is greater than the second rotational speed. When the adsorption refrigeration system group enters an adsorption refrigeration mode, the outdoor fan is controlled to operate at a first rotating speed with a larger numerical value so as to improve the heat dissipation effect of the adsorption part and further improve the refrigeration effect of the adsorption refrigeration system; when the adsorption refrigeration system set enters the desorption cold accumulation mode, the heat of the outdoor heat exchanger of the refrigerant heat exchange system is mainly utilized to desorb the adsorption medium of the adsorption part, so that the outdoor fan is controlled to operate at the second rotating speed with a smaller numerical value, the heat radiation of the outdoor fan driving heat to the outdoor environment can be reduced, the heat can be concentrated in the surrounding environment of the adsorption part, and the desorption rate is improved. Here, the double-refrigeration type air conditioner flexibly adjusts the rotating speed of the outdoor fan according to the starting and stopping states of the operation mode of the adsorption refrigeration system set, so that the adsorption refrigeration effect can be improved, and the cold accumulation effect in the desorption cold accumulation mode can be improved.
Illustratively, when the adsorption refrigeration system unit enters an adsorption refrigeration mode, the first rotating speed of the outdoor fan is 700 r/min; and when the adsorption refrigeration system set enters the desorption cold accumulation mode, the second rotating speed of the outdoor fan is 400 r/min.
In some optional embodiments, after controlling the adsorption refrigeration system group to exit the desorption cold storage mode, if the triggering condition of the adsorption refrigeration mode is met, controlling the adsorption refrigeration system group to enter the adsorption refrigeration mode.
In this way, the indoor environment can be refrigerated by the cold energy accumulated in the desorption cold accumulation stage of the adsorption refrigeration system group, and the heat quantity is transferred from the indoor side to the outdoor side by utilizing the adsorption of the adsorbent in the adsorption refrigeration stage, so that the energy consumption is not needed. Through the combination of two refrigeration modes of adsorption refrigeration and refrigerant refrigeration, the power consumption required for maintaining the indoor environment temperature in the range comfortable for users can be effectively reduced, and the use cost of the double-refrigeration type air conditioner is reduced.
