Example 2

In addition to the features of the above embodiments, the present embodiment further defines: the energy storage device 3 is internally provided with an energy storage material, a second fluid channel 6 and a first fluid channel 7, and the second fluid channel 6 and the first fluid channel 7 exchange heat with the energy storage material.

The air conditioner is provided with a compression branch and a working branch, wherein the compression branch is provided with a compressor 2, the air conditioner is also provided with a throttling unit 8, and the working branch is provided with a first heat exchange unit 5, a throttling unit 8 and a first fluid channel 7 which are arranged in series.

The air conditioner is formed with a first circuit and a second circuit, the working branch is disposed in series with the compression branch and formed as a part of the first circuit, and the second heat exchange unit 4 is disposed in series with the second fluid passage 6 and formed as a part of the second circuit.

It can be understood that the air conditioner is provided with a first fan 10 and a second fan 13, the first fan 10 is used for driving the air flow to exchange heat with the second heat exchange unit 4, and the second fan 13 is used for driving the air flow to exchange heat with the first heat exchange unit 5.

Furthermore, the compression branch is formed by a refrigerant pipe connected to an air inlet and an air outlet of the compressor 2, in the first loop, the air outlet of the compressor 2 is connected to the first heat exchange unit 5, and the air return port is connected to the first fluid channel 7, so that the branch of the compressor 2 is connected to the working branch in series. Of course, the present disclosure is not limited thereto, in other embodiments, the compression branch may further include a reversing device, and the reversing device is connected to the gas outlet of the compressor 2, the gas return port, the first heat exchange unit 5 and the first fluid channel 7, so as to control the gas outlet of the compressor 2 to be conducted to the first heat exchange unit 5 via the reversing device, or control the gas outlet of the compressor 2 to be conducted to the first fluid channel 7, so as to control the operation of the first loop via the reversing device to correspondingly control the energy storage material of the energy storage device 3 to store cold or heat.

Further, a first medium is circulated in the first circuit, and a second medium is circulated in the second circuit, wherein, for example, the first medium is a refrigerant; for example, the second medium is water, glycol solution, or other coolant.

More specifically, as shown in fig. 5, the circulation pattern of the first medium is (described taking cold storage as an example): the first medium sent out from the compressor 2 firstly flows through the first heat exchange unit 5 to exchange heat to realize condensation, the condensed first medium enters the throttling unit 8 to be throttled, the throttled first medium enters the first fluid channel 7, the first medium evaporates in the first fluid channel 7 and absorbs heat of the energy storage material, so that the energy storage material is cooled and stored, and then the evaporated first medium flows out from the first fluid channel 7 and returns to the compressor 2 again to complete circulation.

Certainly, in the heat storage process, the first medium sent by the compressor 2 enters the first fluid channel 7, and releases heat to the energy storage material in the first fluid channel 7, so that the energy storage material stores heat, and the first medium dissipates heat and cools to condense, the condensed first medium is throttled by the throttling unit 8, then enters the first heat exchange unit 5 to exchange heat and evaporate, the evaporated first medium flows out of the first heat exchange unit 5, and returns to the compressor 2 again to complete circulation.

As shown in fig. 4, the second medium is circulated in a manner (described by taking cooling as an example): the second medium exchanges heat with the energy storage material in the second fluid channel 6, releases heat to the energy storage material to realize cooling of the second medium, the cooled second medium enters the second heat exchange unit 4, releases cold to the environment through the second heat exchange unit 4, realizes cooling of the environment, and the cooled second medium returns to the second fluid channel 6 again to complete circulation.

Certainly, for the heat supply process, the difference lies in that the second medium exchanges heat with the energy storage material in the second fluid channel 6, absorbs heat from the energy storage material to realize the temperature rise of the second medium, the second medium after the temperature rise enters the second heat exchange unit 4, releases the heat to the environment through the second heat exchange unit 4, realizes the heat supply to the environment, and the second medium after the heat supply returns to the second fluid channel 6 again to complete the circulation.

Further, the air conditioner further comprises a driving device 9, and the driving device 9 is arranged in the second loop and drives the medium in the second loop. The drive means 9 may for example be a water pump, a diaphragm pump or the like. The flow rate of the second medium in the second loop can be adjusted by using the driving device 9, so that the transfer speed of heat or cold from the energy storage material to the environment is correspondingly controlled, and the adjustment of heat supply and cold supply efficiency is realized.

Through the structure of the embodiment, the air conditioner can be controlled to operate according to at least the following enumerated modes according to requirements:

as shown in fig. 5, the first mode: the compressor 2 is started, the first medium circularly runs along the first loop, the first medium is condensed by the first heat exchange unit 5 and throttled by the throttling unit 8, the throttled first medium flows through the first fluid channel 7 of the energy storage device 3, the first medium in the first fluid channel 7 evaporates and absorbs heat, so that the energy storage material around the first fluid channel 7 stores cold, the first medium in the first fluid channel 7 evaporates and absorbs heat, water in the energy storage device 3 is converted into ice in the process of evaporating and absorbing heat by taking water as the energy storage material for illustration, the cold is stored, and when all water in the energy storage device 3 is converted into ice, the first medium circularly stops; the first mode can also be called as a single cold accumulation mode, the cold accumulation of the energy storage device 3 is realized, the driving device 9 does not work, the second medium in the second loop does not circulate, and the cold is not supplied to the outside.

As shown in fig. 4, the second mode: the compressor 2 does not work, and the first loop stops running; the driving device 9 is started, the second medium circularly works along the second loop, wherein the second medium with higher temperature exchanges heat with the energy storage material in the energy storage device 3 in the second fluid channel 6, so that the temperature of the second medium is reduced after the second medium releases heat, the second medium cooled by the energy storage material enters the second heat exchange unit 4, the first fan 10 drives the airflow to exchange heat with the second heat exchange unit 4, the cold quantity of the second medium in the second heat exchange unit 4 is released to the environment, and the air conditioner is enabled to supply cold to the outside. Wherein, because the compressor 2 does not work, the air conditioner does not release heat to the outside in the process of cooling.

As shown in fig. 6, the third mode: the compressor 2 and the drive 9 are both started, the first medium circulates along the first loop, and the second medium circulates along the second loop; the first medium is used for absorbing heat to make ice in the energy storage device 3, so that the energy storage material is cooled and cold energy is continuously stored, meanwhile, the second medium releases heat to the energy storage material in the energy storage device 3 to reduce the temperature of the second medium, so that the second medium is cooled and then supplies cold to the environment, and therefore the using functions of air conditioning, cold storage and cold supply are achieved, and cold supply to the outside is continuously performed.

Further, in the third mode, the amount of heat exchange between the first circuit and the second circuit can be adjusted by flow control of the driving device 9 (specifically, for example, a water pump) to adjust the cold distribution for cold storage and cold supply. Specifically, the larger the flow of the driving device 9 is, the larger the cold energy obtained by the environment through the second heat exchange unit 4 is, the slower the cold storage rate of the energy storage material in the energy storage device 3 is, for example, the slower the icing rate in the energy storage device 3 is; conversely, the smaller the flow of the drive device 9, the faster the cold storage rate of the energy storage material in the energy storage device 3, for example the faster the icing rate within the energy storage device 3. When the energy storage material in the energy storage device 3 is saturated in cold storage, for example, water in the energy storage device 3 is completely frozen, the compressor 2 is stopped, and the first medium stops running along the first loop; when the cold quantity of the energy storage material in the energy storage device 3 is not enough to provide the cold quantity, for example, the volume of the ice in the energy storage device 3 is not enough to provide the cold quantity, the compressor 2 is started, and the first medium starts to circularly make ice along the operation of the first loop, so that the use function of continuously supplying the cold to the outside by the air conditioner is realized, and the use requirement of a user can be further met.

Through the embodiment, the work of the two loops can be controlled respectively, the regulation and the selection of the energy storage process and the energy release process of the product can be realized, the product is iterated to have richer use functions and modes, and the user requirements can be met.

One, single cold storage mode

The cold storage only mode: the compressor 2 is started, the refrigerant circularly runs, the refrigerant is condensed by the first heat exchange unit 5 and throttled by the throttling unit 8, the throttled refrigerant flows through the first fluid channel 7 of the energy storage device 3, and the refrigerant in the first fluid channel 7 evaporates and absorbs heat, so that the energy storage material around the first fluid channel 7 stores cold energy, taking liquid or solid water as the energy storage material for example to explain, in the process of evaporating and absorbing heat of the refrigerant in the first fluid channel 7, the water in the energy storage device 3 is converted into ice to store the cold energy, and when all the water in the energy storage device 3 is converted into ice, the refrigerant circularly stops; in this process, the drive unit 9 is not operated, and the coolant circuit is not circulated, thereby not supplying cooling to the outside.

Two, single cooling mode

Single cooling mode: the compressor 2 does not work, and the operation of the refrigerant is stopped; the driving device 9 is started, the secondary refrigerant works in a circulating mode, wherein the secondary refrigerant with high temperature exchanges heat with the energy storage material in the energy storage device 3 in the second fluid channel 6, so that the secondary refrigerant emits heat to reduce the temperature, the secondary refrigerant cooled by the energy storage material enters the second heat exchange unit 4, and the first fan 10 drives airflow to exchange heat with the second heat exchange unit 4, so that the cold of the secondary refrigerant in the second heat exchange unit 4 is released to the environment, and the air conditioner supplies cold to the outside.
