Further, in the first circuit, the discharge port of the compressor 2 is connected to the first heat exchange unit 5, and the return port is connected to the first fluid passage 7. Of course, the present disclosure is not limited to this, and in other embodiments, the reversing device may be further included, 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 circuit via the reversing device to correspondingly control the energy storage material of the energy storage device 3 to store cold or heat.

Furthermore, a first medium flows through the first circuit, and a second medium flows through the second circuit, wherein, for example, the first medium is a refrigerant, and the second medium is water, glycol solution or other refrigerating medium.

More specifically, as shown in fig. 7, 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.

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 driving means 9 may for example be a water pump, a diaphragm pump, etc. 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.

as shown in fig. 7, 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. 6, 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 second 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. 8, 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.

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 higher 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 secondary refrigerant drives airflow to exchange heat with the second heat exchange unit 4 through the second fan 10, 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.

The single cold supply mode does not need the operation of the compressor 2, the only power part is the driving device 9, the storage battery can be adopted to supply power to the driving device 9, and the refrigeration without plugging in electricity can be realized. The single cooling mode does not need to radiate heat to the outside through the first heat exchange unit 5, and only cooling and no heat radiation can be realized.

Three, ice storage and cold supply mode

Ice storage and cold supply mode: the compressor 2 and the driving device 9 are both started, the refrigerant circulates and operates, and the secondary refrigerant circulates and operates; the refrigerant makes ice through heat absorption in the energy storage device 3, so that the energy storage material is cooled, and meanwhile, the secondary refrigerant releases heat to the energy storage material in the energy storage device 3, so that the temperature of the secondary refrigerant is reduced, the secondary refrigerant is cooled and then supplies cold to the environment, and the using function of continuously supplying cold to the outside by the air conditioner is realized.

To enhance the cold exchange between the coolant cycle and the coolant cycle, subcoolers 12 can be provided before the inlet of the first flow path 7 of the coolant cycle and after the outlet of the second flow path 6 of the coolant cycle to lower the coolant temperature and release more cold to the environment.

The driving device 9 is a water pump, and is connected in series in the coolant cycle, and the flow rate of the driving device 9 (specifically, for example, the water pump) is used to adjust the heat exchange amount between the coolant cycle and the coolant cycle, so as to adjust the cold distribution of cold storage and cold supply. The larger the flow of the driving device 9 is, the larger the cold quantity 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 refrigerant cycle stops running; when the cold energy of the energy storage material in the energy storage device 3 is not enough to provide the cold energy, for example, the volume of the ice in the energy storage device 3 is not enough to provide the cold energy, the compressor 2 is started, and the refrigerant cycle starts to make ice, 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.

Four, heating mode

Heating mode: the compressor 2 and the driving device 9 are stopped, and the refrigerant cycle and the secondary refrigerant cycle are stopped; the electric heating device 11 is electrified, the second fan 10 is electrified, and the air flow is driven to exchange heat with the electric heating device 11 and then discharged into the environment, and the heating mode is switched.
