[0004] The utility model discloses to solve the above-mentioned technical problems, and provide a kind of mobile energy storage air conditioner, which can reduce energy consumption and improve refrigeration effect.

[0005] The utility model discloses the purpose can be realized by the following technical scheme: a kind of mobile energy storage air conditioner, including the shell that the air inlet and air outlet are respectively set up on opposite two side walls, the shell is installed with fan at air inlet or air outlet, and it is equipped with energy storage tank, evaporator and water storage tank in shell, it is characterized in that, the top of the energy storage tank is open and located between air inlet and air outlet, the water storage tank is located below energy storage tank, the evaporator is located in energy storage tank, the bottom of the energy storage tank is connected with downcomer, and the water outlet end of the downcomer is downward and communicated to water storage tank, and electric valve is installed on downcomer.

[0006] The shell is made of thermal insulation material, the energy storage tank and the evaporator are fixed in the shell, the evaporator is connected with the external compressor and condenser, the air inlet and air outlet are located on the left and right sides of the shell, and the top opening of the energy storage tank is located between the air inlet and the air outlet. When ice needs to be stored at night, the electric valve on the drain pipe is closed and the drain pipe is blocked, the evaporator makes ice in the energy storage tank, and the ice is condensed on the evaporator. When cold air needs to be released during the day, the electric valve on the drain pipe is turned on to open the drain pipe, the water in the energy storage tank that has not frozen is discharged into the water storage tank, so that the ice is completely exposed to the air, the fan is turned on, the airflow enters the shell from the air inlet and enters the energy storage tank from the top opening, exchanges heat with the outer surface of the ice, and then blows out from the air outlet. The ice is made at night and the cold air is obtained during the day, thereby reducing energy consumption. Because the bottom of the energy storage tank is connected to the drain pipe, the water melted by the ice can also be quickly discharged into the water storage tank, so that the ice is always in an exposed state and the airflow can always exchange heat with the entire outer surface of the ice, improving the refrigeration effect.

[0007] In the above mobile energy storage air conditioner, a water pump is further arranged in the shell, a water inlet end of the water pump is connected to the water storage tank through a water inlet pipe, and a water outlet end of the water pump is connected to a water outlet pipe, an outlet end of the water outlet pipe extends upward to above the opening of the energy storage tank, and a water outlet end port of the water outlet pipe is opposite to the opening of the energy storage tank. When ice needs to be stored at night, the water pump can transport the water in the water storage tank to the energy storage tank, and the water in the energy storage tank melted by the ice is discharged into the water storage tank from the drain pipe during the day, realizing water circulation in the shell.

[0008] In the above mobile energy storage air conditioner, the air inlet and the air outlet are higher than the energy storage tank, and the height of the opening edge of the energy storage tank is consistent with the height of the lower edge of the air outlet. The air inlet and the air outlet are higher than the energy storage tank, so that the airflow is not blocked by the sidewall of the energy storage tank, the airflow fully exchanges heat with the ice, and the refrigeration effect is improved.

[0009] In the above mobile energy storage air conditioner, the fan is higher than the energy storage tank, and the fan is inclined and faces the opening at the top of the energy storage tank. The airflow can directly enter the energy storage tank and act on the ice, improving the refrigeration effect.

The fan is higher than the energy storage tank, and the fan is inclined and faces the opening of the energy storage tank, so that the airflow can directly blow to the ice in the energy storage tank under the action of the flow guide shell, reducing wind resistance and noise, and improving the refrigeration effect.

[0011] In the mobile energy storage air conditioner, the two side plates near the air inlet and air outlet are inclined, and the distance between the two side plates gradually increases from bottom to top. The two inclined side plates have a flow guiding effect. The air flow can be blown into the energy storage box along the inclined side plate at the air inlet, so that part of the air flow passes under the ice block and exchanges heat with the lower surface of the ice block, and then is guided to the air outlet by the inclined side plate at the air outlet, thereby improving the refrigeration effect.

[0012] In the mobile energy storage air conditioner, a flow guide plate is further fixed in the shell, the flow guide plate is located above the energy storage box, the middle part of the flow guide plate is horizontally arranged and close to the top opening of the energy storage box, and the two ends of the flow guide plate are bent upward into inclined shapes and respectively face the air inlet and the air outlet. The middle horizontal part of the flow guide plate forms a channel with the upper surface of the ice block. The air flow is guided downward by the inclined part of the flow guide plate near the air inlet, so that the air flow fully acts on the ice block, and then is guided by the inclined part of the flow guide plate near the air outlet, and is blown out of the air outlet, thereby reducing wind resistance and noise and improving the refrigeration effect.

[0013] In the mobile energy storage air conditioner, the evaporator includes a plurality of refrigeration coils, each refrigeration coil is coiled into a plate shape and vertically arranged, the plurality of refrigeration coils are sequentially and spaced arranged along the width direction of the shell, and a ventilation gap opposite to the air inlet is formed between adjacent two refrigeration coils. Each refrigeration coil can condense a flat ice block, and gaps are formed between the plurality of ice blocks. The air flow can fully exchange heat with the plurality of ice blocks, thereby improving the refrigeration effect.

[0014] In the mobile energy storage air conditioner, gaps are formed between the evaporator and the inner side and bottom surface of the energy storage box. After the ice water in the energy storage box is discharged, channels are formed between the surface of the ice block and the inner side and bottom surface of the energy storage box. The air flow can fully exchange heat with the outer surface of the ice block, thereby improving the refrigeration effect.

[0015] In the mobile energy storage air conditioner, a plurality of energy storage boxes are sequentially arranged in the vertical direction, and each energy storage box is provided with the above-mentioned evaporator. This structure makes the volume of the energy storage box and the evaporator relatively small, but the number is relatively large, thereby increasing the heat exchange area with the air flow and improving the refrigeration effect.

[0016] Compared with the prior art, the mobile energy storage air conditioner has the following advantages:

[0017] 1. Since the air conditioner is used to store energy by making ice at night when the electricity consumption is low, and releases cold energy by melting ice during the day when the electricity consumption is high, the air conditioner is more energy-saving.

[0018] 2. Since the bottom of the energy storage box is connected to a drain pipe, the water melted from the ice block can be quickly discharged into the water storage tank, so that the ice block is always exposed, and the air flow can always exchange heat with the entire outer surface of the ice block, thereby improving the refrigeration effect.
