It is worth noting that the existing energy storage type mobile air conditioner can only be used for storing ice and refrigerating in summer, and cannot meet the requirement that a user can also heat and warm in winter.

And in the technical scheme of the utility model, the mobile air conditioner includes cold-storage module and heat transfer module, wherein, the cold-storage module includes compressor 11, condenser 12 and evaporimeter 13, and compressor 11, condenser 12 and evaporimeter 13 communicate in proper order and form the cold-storage loop, and heat transfer module includes heating device 21, first heat exchanger 22 and first liquid pump 23, and first heat exchanger 22 and first liquid pump 23 intercommunication and form the heating loop, and heating device 21 is used for heating to the heat-transfer liquid in the heating loop. The utility model discloses among the technical scheme, the cold-storage module is used for carrying out the cold-storage in order to supply the refrigeration, and heat exchange module is used for heating to make mobile air conditioner can be used for the refrigeration of ice-storage in summer, can also satisfy the demand that the user also can heat the heating in winter.

In one embodiment, as shown in fig. 1, the heat exchange module includes a second heat exchanger 24 and a first box 25, a heat exchange medium is contained in the first box 25, the heating device 21 and the second heat exchanger 24 are both disposed in the first box 25, and the second heat exchanger 24 is communicated with the first heat exchanger 22. Specifically, an outlet of the first liquid pump 23, the first heat exchanger 22, the second heat exchanger 24, and an inlet of the first liquid pump 23 are sequentially communicated to form a heating loop, at least a portion of the second heat exchanger 24 is immersed in a heat exchange medium, the heating device 21 heats the heat exchange medium, the heat exchange medium transfers heat to the heat exchange liquid of the second heat exchanger 24, the first liquid pump 23 conveys the heated heat exchange liquid to the first heat exchanger 22, and the first heat exchanger 22 exchanges heat with outside air to achieve the purpose of heating. In this embodiment, the heat exchange module may operate in a heating mode or a cooling mode (in which the heating device 21 does not operate). That is, the outlet of the first liquid pump 23, the first heat exchanger 22, the second heat exchanger 24, and the inlet of the first liquid pump 23 are sequentially connected to form a loop, which can be used for cooling as well as heating. In addition, the heat exchange liquid filled in the loop can be used as a heat carrying agent and a secondary refrigerant.

Further, the evaporator 13 is disposed in the first tank 25. It can be understood that when the heat exchange module can both heat and heat, the heat exchange medium in the first box 25 needs to satisfy the condition of conducting heat and storing cold. In this embodiment, the heat exchange medium is water. The evaporator 13 is disposed in the first tank 25 to be in contact with water in the first tank 25. In the cold storage mode, after entering the evaporator 13, the low-temperature and low-pressure refrigerant exchanges heat with water, and then the water is cooled to ice cubes or ice-water mixture below 0 ℃ so as to store cold. In the cooling mode, the heat exchange module cools by using the cooling capacity stored in the first box 25.

Further, as shown in fig. 1, the first heat exchanger 22 is disposed above the condenser 12, and the first tank 25 is disposed below the condenser 12. It can be understood that, because the heat exchange medium is contained in the first box 25, the first box 25 is heavy and is arranged at a position which is lower than the middle of the mobile air conditioner, so that the center of gravity of the mobile air conditioner is lower, and the stability of the whole mobile air conditioner is facilitated.

In another embodiment, as shown in fig. 2, the heat exchange module further includes a third heat exchanger 26, a second liquid pump 27 and a fourth heat exchanger 28, the third heat exchanger 26 is disposed in the first tank 25, and the third heat exchanger 26, the second liquid pump 27 and the fourth heat exchanger 28 are sequentially communicated to form a refrigeration loop. In this embodiment, in the heating mode and the cooling mode, the same box and the heat exchange medium are shared, but the heat exchanger is not shared. The outlet of the first liquid pump 23, the first heat exchanger 22, the second heat exchanger 24 and the inlet of the first liquid pump 23 are sequentially communicated to form a heating loop only for heating, and the outlet of the second liquid pump 27, the fourth heat exchanger 28, the third heat exchanger 26 and the inlet of the second liquid pump 27 are sequentially communicated to form a cooling loop only for cooling. It is understood that the heating mode and the cooling mode do not share the same loop, and different heat exchange fluids can be respectively filled in different loops. The refrigeration loop may be filled with an anti-freezing fluid (e.g., glycol solution) to prevent the heat-exchange fluid from freezing due to low temperature during the refrigeration process, which could cause the refrigeration loop to be blocked. The heating loop can be filled with water because the specific heat capacity of the water is large and the cost is low, and the phenomenon of freezing and icing can not occur in the heating mode. In addition, it can be understood that since the user generally performs cooling in summer and heating in winter, heating and cooling are not performed simultaneously, and thus, the two modes can share the same cabinet. And the heating device 21, the second heat exchanger 24 and the third heat exchanger 26 are all arranged in the same box body, so that the internal structure of the mobile air conditioner can be more compact, and the size of the mobile air conditioner can be reduced.

In an embodiment, as shown in fig. 3, the mobile air conditioner further includes a second box 29, a third heat exchanger 26, a fourth heat exchanger 28, and a second liquid pump 27, the phase change cold storage material is contained in the second box 29, the evaporator 13 and the third heat exchanger 26 are both disposed in the second box 29, and the third heat exchanger 26, the second liquid pump 27, and the fourth heat exchanger 28 are sequentially communicated to form a refrigeration loop. In this embodiment, the cooling mode and the heating mode do not share the heat exchanger and do not share the same box. It can be understood that, when the cooling mode and the heating mode share the box, if the mobile air conditioner is switched from the cooling mode to the heating mode in a short time, the heating device 21 needs to reheat the cold water in the box to hot water, so that the heating device 21 consumes more energy. Therefore, compared with the technical scheme that the box is shared by the cooling mode and the heating mode, in the technical scheme of the embodiment, even if the two modes are switched with each other in a short time, the heat exchange efficiency of the two modes is not influenced.

Further, as shown in fig. 3, the mobile air conditioner includes a housing 30, the housing 30 is provided with a first air inlet 31, a first air outlet 32, and a first air duct communicating the first air inlet 31 and the first air outlet 32, and the first heat exchanger 22 and the fourth heat exchanger 28 are both disposed in the first air duct. It can be understood that, in the heating mode, after the indoor air enters the first air duct through the first air inlet 31 and exchanges heat with the first heat exchanger 22, the air carrying heat is blown out through the first air outlet 32 again to heat the indoor environment. In the cooling mode, after the indoor air enters the first air duct through the first air inlet 31 and exchanges heat with the fourth heat exchanger 28, the air carrying cooling capacity is blown out through the first air outlet 32 to cool the indoor environment. Of course, in other embodiments, the first heat exchanger 22 and the fourth heat exchanger 28 may be disposed within different air paths, respectively.

Further, the housing 30 is further provided with a second air inlet 33, a second air outlet 34 and a second air duct communicating the second air inlet 33 and the second air outlet 34, and the condenser 12 is disposed in the second air duct. It can be understood that, in the cold storage process, after the indoor air enters the second air duct through the second air inlet 33 and exchanges heat with the cold storage condenser 12, the air carrying heat is blown out through the second air outlet 34 to dissipate heat of the cold storage condenser 12.

In this embodiment, as shown in fig. 3, the mobile air conditioner further includes a first fan 41 and a second fan 42, where the first fan 41 is disposed in the first air duct, and the second fan 42 is disposed in the second air duct. It is understood that the first fan 41 and the second fan 42 may be a cross-flow fan, an axial flow fan, a centrifugal fan, or the like. The flow of air in the first air duct can be accelerated by the operation of the first fan 41, thereby accelerating the heat exchange efficiency of the first heat exchanger 22 and the fourth heat exchanger 28. And the flow of air in the air duct can be accelerated by the operation of the second fan 42, thereby accelerating the heat exchange efficiency of the condenser 12.

Further, as shown in fig. 3, the first heat exchanger 22 and the fourth heat exchanger 28 are both disposed above the condenser 12, and the first tank 25 and the second tank 29 are both disposed below the condenser 12. It can be understood that, because the heat exchange medium is contained in the first box 25 and the phase change cold storage material is contained in the second box 29, the first box 25 and the second box 29 are heavy and are arranged at the lower position in the mobile air conditioner, so that the center of gravity of the mobile air conditioner is lower, and the stability of the whole mobile air conditioner is facilitated. In addition, the first box 25 and the second box 29 are insulation boxes, and specifically, the shells 30 of the first box 25 and the second box 29 both include insulation layers, so as to avoid loss of heat in the first box 25 and cold in the second box 29.

Further, the heating device 21 is an electric heater. The electric heater includes any one of an electromagnetic heater, an infrared heater, a resistance heater, and the like. In this embodiment, the resistance heater is used to heat the heat transfer medium in the first tank 25.
