The state switching module 300 may further be configured to control the second solenoid valve 202 to be closed, and control the first water pump 204 and the first water pump 205 to be opened, so as to switch the operation state of the auxiliary refrigeration module 200 to a refrigeration state, at this time, auxiliary refrigeration may be performed through the first heat exchange circuit and the second heat exchange circuit while refrigeration is performed through the conventional refrigeration circuit.
Further, with continued reference to fig. 2, in a conventional refrigeration circuit, a first end of the compressor 101 is connected to a first end of the condenser 102; a second end of the condenser 102 is connected with a first end of the supercooling heat exchanger 103; a second end of the supercooling heat exchanger 103 is connected with a first end of the first capillary tube 104; a second end of the first capillary 104 is connected to a first end of the first solenoid 105; a second end of the first solenoid valve 105 is connected with a first end of the evaporator 106; a second end of the evaporator 106 is connected to a second end of the compressor 101.
In the cold storage loop, the second end of the first capillary 104 is also connected with the first end of the second solenoid valve 202; a second end of the second solenoid valve 202 and a first end of the second capillary 203; the second end of the second capillary 203 is connected with the first end of the cold storage heat exchanger 201; a second end of the cold storage heat exchanger 201 is connected to a first end of the evaporator 106.
In the first heat exchange loop, the second end of the cold accumulation heat exchanger 201 is also connected with the first end of the first water pump 204; a second end of the first water pump 204 is connected with a first end of the supercooling heat exchanger 103; the second end of the supercooling heat exchanger 103 is also connected with the first end of the cold storage heat exchanger 201.
In the second heat exchange loop, the first end of the cold storage heat exchanger 201 is also connected with the first end of the first water pump 205; a second end of the first water pump 205 is connected with a first end of the evaporator 106; the second end of the evaporator 106 is also connected to the second end of the cold storage heat exchanger 201.
It should be understood that the auxiliary refrigeration module 200 may also include an energy storage module, which may include an energy storage device, and may be a holding tank, which includes a heat exchanger and coolant. When the energy storage and cold accumulation start to work, part of refrigerants of the refrigerating system enter the heat exchanger in the water tank, the part of refrigerants absorb the heat of the secondary refrigerants, are converted into a vapor state from a liquid state, finally flow into the compressor 101 for compression, are discharged to the condenser 102 for heat dissipation, and are circulated continuously. Meanwhile, the secondary refrigerant in the water tank obtains cold energy to cool, and the cold energy is preserved due to the heat preservation of the water tank. When the auxiliary refrigeration module 200 is activated, the low temperature coolant is operated to transport the cold to a desired location, such as the condenser 102 for subcooling, to increase the output of the evaporator 106 of the refrigeration system, and so forth.
It should be noted that, on the basis of the above structural arrangement, the air conditioner can freely switch between the operation modes according to the operation conditions:
A. in the normal mode, the second solenoid valve 202 is closed, the first water pump 204 and the first water pump 205 are closed, and the auxiliary cooling module 200 is in a closed state, and the system is consistent with a conventional cooling system, and cooling is realized only through the conventional cooling module 100.
B. In the energy storage mode, the second electromagnetic valve 202 is opened, the first water pump 204 and the first water pump 205 are closed, the auxiliary refrigeration module 200 is in the energy storage state, and at the moment, refrigeration is realized through the conventional refrigeration module 100, and cold accumulation can be performed through the auxiliary refrigeration module 200. In this mode, since the second solenoid valve 202 is open, the system increases split: a part of refrigerant passes through the second electromagnetic valve 202 and the second capillary 203 and then enters the cold accumulation heat exchanger 201 for heat exchange, a part of cold energy is stored, the refrigerant passes through the cold accumulation heat exchanger 201 and then enters the compressor 101 for compression, the refrigerant is discharged into the condenser 102 for heat release, and finally the refrigerant flows to the first capillary 104 and the second electromagnetic valve 202 to form a cycle; and the other part of the refrigerant flows into the evaporator 106 after passing through the first electromagnetic valve 105 to carry out conventional refrigeration, releases cold, then enters the compressor 101 to be compressed, is discharged into the condenser 102 to release heat, and finally flows into the first capillary 104 and the first electromagnetic valve 105 to form a cycle.
C. Under the powerful mode, second solenoid valve 202 closes, and first water pump 204 and first water pump 205 open, and supplementary refrigeration module 200 is in the refrigeration state, and at this moment, when realizing refrigerating through conventional refrigeration module 100, still can carry out supplementary refrigeration through supplementary refrigeration module 200. In this mode, since the second solenoid valve 202 is closed, all the refrigerant enters the evaporator 106 for normal cooling, and the cooling capacity is released to reduce the indoor temperature. And after the first water pump 204 is started, the secondary refrigerant obtains cold energy after passing through the cold accumulation heat exchanger 201, becomes low-temperature liquid, enters the supercooling heat exchanger 103 after obtaining power through the first water pump 204, exchanges heat with a cold outlet machine type of the refrigeration system, reduces cold outlet, strengthens the heat exchange amount of the indoor evaporator 106, improves the refrigerating capacity of the system, and the secondary refrigerant of the secondary refrigerant self flows back to the cold accumulation heat exchanger 201 after being heated through the supercooling heat exchanger 103, and circulates like this. After the first water pump 205 is started, part of the coolant flows through the cold accumulation heat exchanger 201 to obtain cold energy, and then the cold energy is changed into low-temperature liquid, the low-temperature liquid enters the evaporator 106 after the power is obtained by the first water pump 205, and exchanges heat with the indoor environment to release the cold energy, and the coolant of the coolant flows back to the cold accumulation heat exchanger 201 after being heated by the evaporator 106, and the circulation is carried out.
It should be understood that the air conditioning system may automatically read the outdoor ambient temperature T4 every Δ T1 time interval, and determine whether the system is in the high temperature cooling condition according to the range of the outdoor ambient temperature T4. Under the low-temperature refrigeration working condition, if the indoor environment temperature T1 is lower than the set temperature Ts and the cold accumulation is not completed, the cold accumulation module is started to operate and then operates in a common mode. Under the high-temperature refrigeration working condition, if the indoor environment temperature T1 is higher than the set temperature Ts and the cold accumulation is sufficient, the powerful mode is started, the water pump is started to operate for delta T3 time, and otherwise, the normal mode is used for operation. Wherein, T1 is the indoor ambient temperature, T4 is the outdoor ambient temperature, Ts is the air conditioner set temperature, Δ T1 is the interval time for detecting the temperature of T4, Δ T3 is the operation time of each period of the powerful mode, Δ T3 < Δ T1, and Ta _ c is the ambient temperature for auxiliary cooling start.
In a specific implementation, as shown in fig. 3, fig. 3 is a system operation flowchart, and T4 may be read at regular intervals to determine whether it is higher than the design value Ta _ c, and if so, it is determined that the system is in a high-temperature working condition; and meanwhile, constantly reading T1 at intervals, judging whether the energy storage capacity is higher than a set value Ts, if so, judging that the cold demand of the room is urgent, firstly judging whether the energy storage capacity of the indoor energy storage module is sufficient by the system, if so, starting an auxiliary refrigeration mode, and starting the water pump 1 and the water pump 2. If the auxiliary refrigeration module 200 has no cold energy, the operation is performed according to a common mode, cold accumulation is performed when the temperature of the room is reached or refrigeration is not needed, and when the condition that the auxiliary refrigeration module 200 is used is reached, the auxiliary refrigeration module 200 is started to rapidly cool the room. T4 may be read at regular intervals to determine if it is above the design value Ta _ c, if not. The system is judged to be in a non-high temperature working condition. And if the energy storage is insufficient, the energy storage mode is started, and the system exits the energy storage mode after the energy storage is sufficient and enters a common mode to operate.
In order to achieve the above object, the present invention further provides an air conditioner, which includes the air conditioning system with auxiliary refrigeration as described above. The specific structure of the air conditioning system with auxiliary refrigeration refers to the above embodiments, and since the air conditioner adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
