Description

Technical Field

[0001] This utility model relates to the field of air conditioning and refrigeration equipment technology, and in particular to a large mobile air conditioner. Background Technology

[0002] Conventional portable air conditioners are single-cooling refrigeration systems. The compressor compresses Freon and sends it to the condenser, where it is cooled by a condenser fan. After cooling, the Freon is throttled through a capillary tube and enters the evaporator to vaporize, which lowers the surface temperature of the evaporator fins. Room temperature air passes through the evaporator surface, and the air cooler fan delivers the cooling energy from the evaporator surface to the place of use, causing the ambient temperature to drop continuously and meet the cooling requirements.

[0003] Currently, conventional mobile air conditioners with single-cooling operation cannot meet the temperature rise requirements of the place of use in winter or low-temperature environments because they lack heating devices.

[0004] In view of this, there is an urgent need for a large-scale mobile air conditioner to solve the above problems. Summary of the Invention

[0005] To help solve the problems existing in the prior art, this utility model provides a large mobile air conditioner, which adopts the following technical solution: including: a cabinet, wherein a compressor, a condenser, an evaporator, a cold air fan, a condenser fan and an electric heater are installed inside the cabinet, and the cabinet is provided with a cold air outlet, a cold air inlet, a condenser air inlet and a condenser air outlet; The electric heater is located on the side of the evaporator closest to the cold air fan; The air outlet of the cold air blower is connected to the cold air outlet. The cold air blower is used to discharge the cold energy generated by the evaporator or the heat generated by the electric heater from the cold air outlet. The air outlet of the condenser blower is connected to the condenser outlet. The compressor's exhaust port is connected to the condenser, and the condenser is connected to the evaporator.

[0006] The cooling fan is positioned above the evaporator, and the condensing fan is positioned above the condenser. The cooling fan and the condensing fan are arranged side by side in the horizontal direction.

[0007] The cold air outlet and the condensate outlet are positioned opposite each other on opposite sides of the cabinet in the horizontal direction.

[0008] There are two cold air outlets and two cold air fans. The two cold air fans are arranged side by side, and the air outlets of the two cold air fans are respectively connected to the two cold air outlets.

[0009] The evaporator is tilted.

[0010] The electric heater consists of multiple heating tubes, which are arranged side by side on the side of the evaporator near the cold air fan.

[0011] The compressor and the condenser are located on the same side of the evaporator.

[0012] A water receiving tank is provided below the evaporator, and a drain pump is installed in the water receiving tank.

[0013] The cabinet is equipped with handles on the outside.

[0014] The bottom of the cabinet is equipped with casters.

[0015] The above-described structure of this utility model can achieve the following beneficial effects: In operation, high-temperature, high-pressure Freon gas flows into the condenser from the compressor's exhaust port. The condenser cools the gas, forming low-temperature, high-pressure Freon liquid. This liquid then passes through a capillary tube for throttling and fully vaporizes in the evaporator. Simultaneously, the refrigerant absorbs heat during vaporization in the evaporator, generating cooling energy which is blown out by a cold air fan through the cold air outlet to cool the service area. The gaseous Freon, after evaporation in the evaporator, flows back to the compressor via the return gas line, thus continuously circulating. In addition to the cooling function, this application also has a heating function. When the ambient temperature needs to be raised, the electric heater is activated (compressor, condenser, and evaporator stop working). The heat generated by the electric heater is delivered to the external environment by the cold air fan, causing the ambient temperature to rise continuously. This application also has a dehumidification function. During dehumidification, the cooling function operates normally, and the electric heater is also activated. The heat generated by the electric heater neutralizes the cooling energy generated by the unit and is delivered to the external environment by the cold air fan. During dehumidification, the ambient temperature of the service area does not change significantly. Attached Figure Description

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0020] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0021] Reference Figure 1-3 A large mobile air conditioner includes: a cabinet 1, which is equipped with a compressor 2, a condenser 3, an evaporator 4, a cold air fan 5, a condenser fan 6, and an electric heater 7. The cabinet 1 is equipped with a cold air outlet, a cold air inlet, a condenser air inlet, and a condenser air outlet. The electric heater 7 is located on the side of the evaporator 4 near the cold air fan 5; The air outlet of the air cooler 5 is connected to the air cooler outlet. The air cooler 5 is used to discharge the cold energy generated by the evaporator 4 or the heat generated by the electric heater 7 from the air cooler outlet. The air outlet of the condenser fan 6 is connected to the condenser outlet. The exhaust port of compressor 2 is connected to condenser 3, and condenser 3 is connected to evaporator 4.

[0022] Based on the above structure, during use, high-temperature, high-pressure Freon gas flows into the condenser 3 from the exhaust port of the compressor 2. After being cooled in the condenser 3, it forms low-temperature, high-pressure Freon liquid. Then, after being throttled by the capillary tube 7, it is fully vaporized in the evaporator 4. Simultaneously, the refrigerant absorbs heat during vaporization in the evaporator 4, generating cooling energy. This cooling energy is blown out by the air cooler 5 through the air outlet to cool the service area. The gaseous Freon, after evaporation in the evaporator 4, flows back to the compressor 2 through the return gas pipeline, thus continuously circulating. In addition to the above-mentioned refrigeration function, this application also has the function of controlling... The heating function involves the electric heater 7 operating when the ambient temperature needs to be raised (compressor 2, condenser 3, and evaporator 4 stop working). The heat generated by the electric heater 7 is delivered to the external environment through a cold air fan, causing the ambient temperature to rise continuously. This application also has a dehumidification function. During dehumidification, the refrigeration function is used normally, and the electric heater 7 is also put into operation. The heat generated by the electric heater 7 is neutralized with the cooling capacity generated by the unit's refrigeration and delivered to the external environment through a cold air fan 5. During the dehumidification process, the ambient temperature of the service area will not change significantly.

[0023] like Figure 3 As shown, the air cooler 5 is positioned above the evaporator 4, and the condenser 6 is positioned above the condenser 3. The air cooler 5 and the condenser 6 are arranged side by side in the horizontal direction, and the air cooler outlet and the condenser outlet are positioned opposite each other on opposite sides of the cabinet 1 in the horizontal direction. In this way, the cold energy generated by the evaporator 4 can be directly discharged through the air cooler 5, while the heat generated by the condenser 3 can be directly discharged through the condenser 6, reducing the circulation time of cold energy and heat energy in the cabinet 1.

[0024] like Figure 2 As shown, there are two cold air outlets and two cold air fans 5. The two cold air fans 5 are arranged side by side, and the air outlets of the two cold air fans 5 are connected to the two cold air outlets respectively. By setting two cold air fans 5, the power of the equipment is increased, and the two air outlets can be connected to pipelines respectively to deliver the cooling capacity to different locations.

[0025] like Figure 3 As shown, the evaporator 4 is tilted, which maximizes the volume of the evaporator 4 within the same space and improves its cooling efficiency. The electric heater 7 consists of multiple heating tubes arranged side by side on the side of the evaporator 4 near the cold air fan 5. In actual use, the evaporator 4 is located between the multiple heating tubes and the cold air inlet, and the cooling energy from the evaporator 4 passes between the multiple heating tubes and is finally discharged through the cold air fan.

[0026] like Figure 3 As shown, the compressor 2 and the condenser 3 are located on the same side of the evaporator 4, thereby reducing the path of Freon gas in the compressor 2 to the condenser 3.

[0027] like Figure 3 As shown, a water collection tank 8 is provided below the evaporator 4, and a drain pump is installed in the water collection tank 8. When the equipment is running in a cooling mode, due to the low evaporation temperature of the evaporator 4, condensation will form on the surface of the evaporator 4 under the corresponding ambient temperature and humidity, producing condensate. After the condensate is collected, it is discharged into the water collection tank 8 through a water pipe, and finally discharged out of the cabinet 1 through the drain pump.

[0028] like Figure 1 and Figure 2 As shown, a handle 9 is provided on the outside of the cabinet 1, and a roller 10 is provided on the bottom of the cabinet 1. Multiple rollers 13 are provided, which can be composed of directional wheels and universal wheels to achieve flexibility in adjusting the position of the cabinet 1. By holding the handle 9, the cabinet 1 can be pushed conveniently to adjust its position.

[0029] Further optimizations include a rainproof structure for the unit, with protective doors installed on exposed electrical components to prevent rainwater and dust from entering during outdoor operation or transfer, ensuring safe operation of the unit.

[0030] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
