Description

Technical Field

[0001] The invention belongs to the technical field of air conditioners and relates to an energy storage air conditioner. Background Art

[0002] In order to encourage users to arrange electricity usage time reasonably and improve the utilization efficiency of power resources, the current peak-valley electricity policy is adopted. During the day, electricity users are concentrated, power supply is tight, and the charging standard is higher; at night, there are fewer electricity users, power supply is sufficient, and the charging standard is lower. Energy storage air conditioners are air conditioning equipment that uses energy to store energy at night and releases cold air during the day.

[0003] As disclosed in the patent document (application number: 201520026951.6), a household low-valley electricity ice-making energy storage air-conditioning multifunctional machine includes a compressor, a condenser, a liquid storage tank, a thermal expansion valve and an energy storage box, wherein the energy storage box includes a box body, which is divided into an upper water chamber and a lower installation chamber by a partition, the lower installation chamber is used to install components such as an evaporator, and the upper water chamber is used to hold water, wherein a fan is installed on the side wall, and the condenser is installed on a U-shaped baffle, which is connected to the top plate of the box body along a vertical sliding connection and supported by a spring, and a pressure block is also provided on the U-shaped baffle. At night, under the action of the pressure block, the condenser descends to the bottom of the upper water chamber and is immersed in water for freezing. During the day, the pressure block is removed, and the U-shaped baffle rises with the condenser under the jacking of the spring, so that the ice formed on the condenser is opposite to the fan.

[0004] The reason for the lifting and lowering of the condenser is that the water level in the upper water chamber cannot be higher than the fan, so the ice cubes formed in the water are lower than the fan, so the ice cubes at the bottom need to be lifted up, which causes the condenser to be lifted up frequently. The condenser is a hard copper tube, so it needs to be connected with a hose to be able to lift and lower, which makes the connection easy to leak, and the condenser that is frequently lifted and lowered is also prone to aging, so the reliability of use is low. The above-mentioned condenser needs to be lifted and lowered because the fan and the ice cubes formed in the water are staggered. Therefore, in order not to move the condenser, the technicians in this field can easily think of moving another relative component, such as enlarging the air outlet so that the fan is lowered to be opposite to the ice cubes. Of course, a gate-like structure needs to be set at the bottom of the fan so that the lower part of the air outlet is blocked after the fan rises. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose an energy storage air conditioner which can improve the reliability of use while ensuring the cooling effect.

[0006] The objective of the present invention can be achieved through the following technical solutions: a storage energy air conditioner, comprising a shell having an air inlet and an air outlet respectively provided on two opposite side walls, the shell having a fan installed at the air outlet or the air inlet, an evaporator provided in the shell, characterized in that the evaporator is fixed on the shell and opposite to the air outlet, a water tank located below the evaporator is also provided in the shell, the water tank has an opening facing upward and opposite to the evaporator above, a driving mechanism capable of driving the water tank to rise and fall is also provided on the shell, and the water tank can rise until the evaporator is located in the water tank.

[0007] The shell is made of thermal insulation material, and the fan is installed at the air inlet or outlet, which can generate airflow from the air inlet to the air outlet. The evaporator is connected to the external compressor and condenser. The present application fixes the evaporator in the shell and always faces the fan on one side. The key point is that there is space under the evaporator. A water tank that can be raised and lowered is set in the shell. The water tank is located below the evaporator, and the volume of the water tank is larger than the volume of the evaporator. Water is filled in the water tank. When ice making and energy storage are needed at night, the water tank is lifted by the driving mechanism. The opening of the water tank faces upward and faces the evaporator above. Therefore, as the water tank rises, the evaporator enters the water tank from the opening of the water tank, the compressor works, the evaporator cools and gradually begins to freeze, and the ice condenses on the outside of the evaporator and gradually becomes larger. As the ice cubes become larger, the cold amount transmitted by the evaporator gradually decreases. There is still a certain amount of liquid water between the ice cubes and the inner wall of the water tank, which can be controlled by volume and power to prevent the ice cubes from adhering to the inner wall of the water tank. When it is necessary to release cold air during the day, the water tank is lowered through the driving mechanism to expose the ice condensed on the evaporator. The entire ice is opposite to the fan, and the airflow generated by the fan can flow from the air inlet on one side of the ice to the air outlet on the other side of the ice. The airflow passes through the surface of the ice and takes away the cold to improve the cooling effect. Therefore, the liftable water tank can avoid the water tank covering the outside of the ice and affecting the release of cold, thereby ensuring the cooling effect. At the same time, the present application adopts a structural design that the water tank lifts water to the evaporator, so that the evaporator made of copper tube does not need to be lifted or lowered, thereby ensuring the structural stability and reliability of the evaporator.

[0008] In the above energy storage air conditioner, the evaporator is plate-shaped, and there are at least two evaporators, and the sides of the two adjacent evaporators are opposite to each other and form a ventilation gap opposite to the air outlet. The plate-shaped evaporator makes the condensed ice cubes in the form of thinner blocks, which have a larger contact area with the airflow and improve the heat exchange efficiency. When multiple evaporators condense into multiple ice cubes, the airflow can exchange heat with the two ice cubes when passing through the gap between adjacent ice cubes, which can not only improve the cooling effect, but also reduce the resistance to the airflow, which is more energy-saving and environmentally friendly.

[0009] In the above energy storage air conditioner, the evaporator is in the shape of a flat plate, and the evaporators are all arranged horizontally and arranged in sequence vertically, or the evaporators are all arranged vertically and arranged in sequence horizontally. The sequentially arranged evaporators make the condensed ice cubes more regularly arranged, and the gaps between the ice cubes for air flow to pass through are arranged more evenly, which can not only improve the cooling effect, but also make the cold air blown out of the air outlet uniform and more comfortable.

[0010] In the above energy storage air conditioner, the evaporator is cylindrical, and the inner hole of the evaporator is arranged horizontally and toward the air outlet. The diameters of all the evaporators are the same and arranged in a matrix, or the diameters of all the evaporators are different, and the evaporator with a smaller diameter is inserted into the evaporator with a larger diameter. The evaporator is cylindrical, so that the condensed ice cubes are cylindrical, and the two ends are respectively opposite to the air inlet and the air outlet, and the airflow passes through the inner and outer sides of the cylindrical ice cubes, respectively, to improve the cooling effect.

[0011] In the above energy storage air conditioner, the driving mechanism includes a lifting frame located above the shell, a plurality of vertically arranged support rods are fixed on the upper side of the shell, a plurality of guide sleeves are fixed on the lifting frame, and the plurality of guide sleeves are respectively slidably sleeved on the plurality of support rods, a plurality of vertically arranged lifting rods are fixed on the lifting frame, and the lower ends of the plurality of lifting rods extend downward into the shell and are fixedly connected to the water tank, and the shell is also provided with a motor, a winch or a cylinder capable of driving the lifting frame to rise and fall. The lifting frame is located above the outside of the shell, and is connected to the water tank inside the shell through the lifting rods. The lifting frame slides with the support rods through the guide sleeves to ensure stability, and is driven by a motor, a cylinder or an oil cylinder, such as the motor is connected to the lifting frame through a screw nut structure, a pulley structure or a pull rope, and the driving end of the cylinder or the oil cylinder is directly connected to the lifting frame, and the structure is stable and the reliability of use is high.

[0012] In the above energy storage air conditioner, the water tank includes an inner box body and an outer box body that are fixedly connected to each other, and a heat preservation cavity is formed between the inner box body and the outer box body. A plurality of guide rods are also vertically fixed in the shell, and a plurality of guide tubes are vertically fixed in the heat preservation cavity, and the lower ends of the plurality of guide rods are respectively slidably inserted in the plurality of guide tubes. The heat preservation cavity plays a heat insulation role. Of course, the inner leaves can be filled with heat preservation materials, so that when the water tank rises and the evaporator is located in the water tank for freezing, the internal ice cubes and liquid water are kept warm, so as to avoid the loss of cold, improve the energy storage freezing efficiency, and save more energy. The guide tube located between the inner box body and the outer box body cooperates with the guide rod fixed in the shell to ensure the stability of the water tank lifting and lowering and the position accuracy after lifting and lowering. For example, a more accurate position after rising can ensure that the position of the ice cubes on the evaporator is more accurate and the thickness is more uniform, thereby improving the refrigeration effect. A more accurate position after falling can ensure that the liquid water melted can fall into the water tank relative to the ice cubes above, thereby improving the reliability of use.

[0013] In the above energy storage air conditioner, the side of the water tank facing the air inlet and the air outlet is against the inner side of the shell, and when the water tank rises until the evaporator is located in the water tank, the water tank can cover the air inlet and the air outlet. After the water tank rises, the air inlet and the air outlet can be covered by the side wall to avoid the loss of cold during ice making, improve ice making efficiency, and save energy. In addition, this structure does not need to additionally set a cover plate for the air inlet and the air outlet, and a driving member for driving the cover plate to open and close, so that the water tank can be used for two purposes, reducing production costs, and reducing driving components can also simplify the structure and improve reliability.

[0014] In the above energy storage air conditioner, there are several groups of evaporators, and the groups of evaporators are arranged vertically in sequence. A water tank is provided below each group of evaporators. The water tanks are fixedly connected, and the water tank can rise to the upper adjacent group of evaporators located in the water tank. There are several air inlets, and the air inlets are respectively opposite to the groups of evaporators. Each side of the water tank is vertically fixedly connected with a baffle, and when the water tank rises, the baffle can cover the air inlet. This structure divides the evaporator into several groups, and the height of the evaporator of each group is reduced, so that the height of the water tank is reduced, which reduces the stroke of the water tank lifting and lowering, and reduces the working energy consumption. When the water tank rises to make ice, the baffle can cover the air inlet, reduce the loss of cold, and improve the ice making efficiency.

[0015] In the above energy storage air conditioner, the water tank includes an annular frame and a waterproof bag with the bag opening fixedly connected to the frame, the above lifting rod is fixedly connected to the frame, a water receiving bucket is also provided in the shell, the opening of the water receiving bucket faces upward and is located below the water tank, and a water pump capable of transferring the water in the water receiving bucket to the waterproof bag is also provided in the shell. The structure and volume of the hard water tank need to match the volume of the evaporator and the ice cubes after condensation, so the hard water tank has a relatively high height, and a space larger than the height of the water tank must be reserved below the evaporator in the shell. For this purpose, a waterproof bag is designed. When the frame rises, the waterproof bag is unfolded and sleeved on the outside of the evaporator, and the water pump delivers water to the waterproof bag. When the waterproof bag descends, the bottom of the waterproof bag first contacts the water receiving bucket. As the frame further descends, the waterproof bag can be gradually folded, and the internal water enters the water receiving bucket. This structure can make full use of the horizontal space at the bottom of the shell, reduce the height of the water receiving bucket, and make the height of the entire shell lower and the structure more compact.

[0016] In the above energy storage air conditioner, a support plate is also fixed horizontally in the shell, the support plate is located below the waterproof bag, and the area of ​​the support plate is smaller than the area of ​​the barrel mouth of the water receiving bucket. A plurality of protective rods are vertically fixed to the edge of the side surface of the support plate, and the plurality of protective rods are arranged in sequence along the edge of the support plate. A plurality of guide holes are opened along the length direction of the frame, and the plurality of protective rods pass through the plurality of guide holes of the frame respectively. The bottom of the waterproof bag is supported on the support plate. When the frame rises, the support plate can bear the weight of the liquid water in the waterproof bag, thereby improving the reliability of the waterproof bag. When the frame descends, there is no need to enter the water receiving bucket. The waterproof bag quickly begins to fold under the blocking of the support plate, and the water falls into the water receiving bucket below. The setting of the support plate can not only support the waterproof bag, improve the reliability of use, but also reduce the lifting stroke of the frame.

[0017] In the above-mentioned energy storage air conditioner, a heat exchanger is installed at the air outlet of the shell, and a water pump is also provided in the shell. The water inlet end of the water pump is connected to the water tank through a water inlet pipe, and the water outlet end of the water pump is connected to the water inlet of the heat exchanger through a water outlet pipe, and the water outlet of the heat exchanger is connected to the water tank through a return pipe.

[0018] The temperature of the ice water after the ice cubes melt is still relatively low, so a heat exchanger is installed at the air outlet. The water pump can transport the ice water after the ice cubes melt in the water tank to the heat exchanger. The airflow cooled by the ice cubes can further exchange heat with the heat exchanger when passing through the air outlet, thereby further reducing the airflow temperature, improving the cooling effect, and making full use of the cooling capacity. Of course, an auxiliary evaporator can also be added to the water tank. When the temperature of the ice water in the water tank rises, the auxiliary evaporator can be used to cool the water in the water tank to ensure the cooling effect of the heat exchanger on the airflow.

[0019] Compared with the prior art, this energy storage air conditioner has the following advantages:

[0020] 1. Since a water tank that can be raised and lowered is provided in the shell, water is lifted to the evaporator through the water tank for ice making, so that the evaporator made of copper tube does not need to be raised and lowered, thereby ensuring the structural stability and reliability of the evaporator.

[0021] 2. When releasing the cold air, the water tank is lowered by the driving mechanism, so that the ice condensed on the evaporator is exposed. The whole ice is opposite to the fan, and the airflow passes through the surface of the ice and takes away the cold to improve the cooling effect. Therefore, the liftable water tank can avoid the water tank covering the outside of the ice and affecting the release of cold air, thereby ensuring the cooling effect.

[0022] 3. Since the side of the water tank is against the inner side of the shell, when the water tank rises to the point where the evaporator is located inside the water tank, the water tank can cover the air inlet and outlet to avoid the loss of cold during the ice-making process, improve the ice-making efficiency, and save more energy.

[0023] 4. Since the water tank adopts a waterproof bag, when the frame rises, the waterproof bag is unfolded and put on the outside of the evaporator. When the waterproof bag descends, it quickly begins to fold under the blocking of the support plate, and the water falls into the water collecting bucket below. The setting of the support plate can not only support the waterproof bag and improve the reliability of use, but also reduce the lifting stroke of the frame.

[0024] 5. Since a heat exchanger is installed at the air outlet, the water pump can transport the ice water melted from the ice in the water tank to the heat exchanger. The airflow cooled by the ice can further exchange heat with the heat exchanger when passing through the air outlet, thereby further reducing the airflow temperature, improving the cooling effect, and making full use of the cooling capacity.
