Description

Technical Field

[0001] This application relates to the field of air conditioning and refrigeration equipment technology, and in particular to an industrial mobile air conditioner. Background Technology

[0002] An air conditioner is a refrigeration circulation device. Its core principle is to use a compressor to circulate refrigerant between the evaporator and condenser, absorbing indoor heat and dissipating it to the outside, thus achieving rapid cooling. It is widely used in factories and commercial venues.

[0003] When the air conditioner is running in cooling mode, due to the low evaporation temperature of the evaporator, condensation will form on the surface of the evaporator and produce condensate. The condensate will drip into the water storage tank. When the liquid in the water storage tank reaches a certain height, the operator will pull the water storage tank out of the cabinet and pour out the liquid. Finally, the water storage tank will be reassembled into the cabinet.

[0004] The above-mentioned method of manually pulling out water buckets to handle condensate in air conditioners is labor-intensive, time-consuming, and inefficient. Summary of the Invention

[0005] To address the problem of high labor intensity, time-consuming and inefficient drainage caused by manually pulling out water tanks to handle condensate from air conditioners, this application provides an industrial mobile air conditioner with the following technical solution: It includes a cabinet with a cold air inlet and a cold air outlet. A cooling unit for producing cold air is installed inside the cabinet. The cooling unit communicates with the outside air through the cold air inlet, and an output unit for discharging cold air is installed at the cold air outlet. A water storage tank is located inside the cabinet below the cooling unit. A drain pump is installed inside the cabinet, and the outlet end of the drain pump is connected to an outlet pipe, which extends out of the cabinet.

[0006] In one specific implementation scheme, the cooling unit includes a compressor, a condenser, an evaporator, a cold air fan, and a condensing fan housed within a cabinet. The liquid inlet of the water storage tank is located below the condenser. The cabinet has a condensing inlet and a condensing outlet. The refrigerant of the compressor passes sequentially through the condenser and the evaporator. The cold air fan is used to discharge the cold air generated by the evaporator from the cold air outlet. The condensing fan is used to discharge the heat generated by the condenser from the condensing air outlet. A circulation pipe is connected to the evaporator, and the end of the circulation pipe away from the evaporator is connected to the compressor.

[0007] In one specific implementation, the output unit includes a cold air outlet duct disposed at the cold air outlet, the outlet end of which extends out of the cabinet.

[0008] In one specific implementation, the cold air outlet duct is a corrugated pipe.

[0009] In one specific implementation, the water storage tank is equipped with a liquid level sensor, and the liquid level sensor is lower than the highest liquid level in the water storage tank.

[0010] In one specific implementation, a filter screen is provided between the cold air inlet and the evaporator.

[0011] In one specific implementation scheme, the cabinet has an annular mounting groove corresponding to the cold air inlet, and the filter screen is inserted into the annular mounting groove.

[0012] In one specific implementation, the water storage tank is provided with a pull handle on the end face facing the cold air inlet.

[0013] In one specific implementation, the output of the condenser is connected to the evaporator via a throttling unit, which is a capillary tube.

[0014] In one specific feasible implementation, the bottom of the cabinet is provided with several casters.

[0015] In summary, this application has the following beneficial technical effects: When a water storage tank is selected, the condensate from the cooling unit drips into the water storage tank. After the condensate in the water storage tank accumulates to a certain height, the industrial mobile air conditioner issues a full water alarm and stops, and the accumulated condensate in the water storage tank is manually emptied. When a drain pump is selected, the condensate from the cooling unit drips into the drain pump. After the condensate in the drain pump accumulates to a certain height, the drain pump is started, and the condensate is discharged from the cabinet through the liquid outlet pipe, realizing automatic treatment of the condensate in the air conditioner, saving labor costs, saving time and effort, and improving drainage efficiency.

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

[0021] This application discloses an industrial mobile air conditioner.

[0022] Reference Figure 1 and Figure 2 The industrial mobile air conditioner includes a cabinet 1, with four evenly distributed casters 16 installed at the bottom of the cabinet 1. Alternatively, depending on the actual site conditions, the four casters 16 can be replaced with a combination of two fixed casters and two casters 16. The casters 16 can rotate 360 ​​degrees, allowing the air conditioner to move easily in any direction, including forward, backward, sideways, and diagonally, thus improving the flexibility of the air conditioner's position.

[0023] Reference Figure 2 and Figure 3 The cabinet 1 has a cold air inlet 2 and a cold air outlet 3. The cold air inlet 2 is located on the side of the cabinet 1, and the cold air outlet 3 is located on the top of the cabinet 1. A cooling unit for producing cold air is installed inside the cabinet 1. The cooling unit is connected to the outside air through the cold air inlet 2, and an output unit for outputting cold air is installed on the cold air outlet 3. A water storage tank 11 is installed inside the cabinet 1 and is located below the cooling unit. A pull handle 14 is installed on the end of the water storage tank 11 facing the cold air inlet 2, which allows the operator to easily and conveniently pull the water storage tank 11 out of the cabinet 1. A drain pump 4 is installed inside the cabinet 1. The outlet end of the drain pump 4 is connected to a drain pipe 5, and part of the drain pipe 5 extends out of the cabinet 1. The water storage tank 11 and the drain pump 4 can be interchanged according to the actual site conditions.

[0024] Reference Figure 2 and Figure 3 The cooling unit includes a compressor 6, a condenser 7, an evaporator 8, a cold air fan 9, and a condensing fan 10, all housed within a cabinet 1. The inlet of a water storage tank 11 is located below the condenser 7. The cabinet 1 has a condensing inlet and a condensing outlet 17. The refrigerant from the compressor 6 passes sequentially through the condenser 7 and the evaporator 8. In this embodiment, the refrigerant can be Freon. The cold air fan 9 discharges the cold air generated by the evaporator 8 from the cold air outlet 3. The condensing fan 10 discharges the heat generated by the condenser 7 from the condensing air outlet. A circulation pipe is connected to the evaporator 8, with one end of the circulation pipe opposite to the evaporator 8 connected to the compressor 6. The output end of the condenser 7 is connected to the evaporator 8 through a throttling unit, which is a capillary tube 15. The capillary tube 15 acts as a throttling and pressure-reducing element, facilitating the change of the refrigerant from a high-pressure liquid state to a low-pressure mist-like gas-liquid mixture.

[0025] Therefore, during refrigeration operation, high-temperature and high-pressure Freon gas flows from compressor 6 into condenser 7 for cooling, thereby forming low-temperature and high-pressure Freon liquid. At the same time, the heat generated by Freon in condenser 7 is discharged from condenser outlet 17 by condenser fan 10, that is, hot air is discharged from cabinet 1. Then, Freon is fully vaporized in evaporator 8 after being throttled by capillary tube 15. The cooling capacity generated by the refrigerant absorbing heat during vaporization in evaporator 8 is blown out by cold air fan 9 through cold air outlet 3 to achieve cooling of the service area.

[0026] Reference Figure 2 and Figure 3 The output unit includes a cold air outlet duct installed at the cold air outlet 3. The outlet end of the cold air outlet duct extends out of the cabinet 1. The cold air outlet duct adopts a corrugated pipe 12. In this embodiment, the cold air outlet duct adopts two corrugated pipes 12 arranged in parallel, which further improves the efficiency of cold air discharge. At the same time, the direction of cold air blowing out can be adjusted through the corrugated pipe 12, making it more flexible.

[0027] Reference Figure 2 and Figure 3 A filter screen 13 is installed between the cold air inlet 2 and the evaporator 8. The filter screen 13 effectively isolates dust and other impurities in the air. The cabinet 1 has an annular mounting groove corresponding to the position of the cold air inlet 2. The filter screen 13 is inserted into the annular mounting groove. Customers can remove the filter screen 13 from the annular mounting groove for easy cleaning and maintenance.

[0028] Reference Figure 2 and Figure 3 A liquid level sensor is installed inside the water storage tank 11. The liquid level sensor is below the highest liquid level in the water storage tank 11. When the liquid level in the water storage tank 11 reaches the detection end of the liquid level sensor, the liquid level sensor sends a full water signal to the control terminal. The control terminal then controls the compressor 6, the air cooler 9, etc., to stop and issues a full water warning for the water storage tank 11.

[0029] It should be noted that in this embodiment, a separate water storage tank 11 or a separate drain pump 4 can be set up according to the actual site conditions, and no restriction is placed here. The condensate from the cooling unit drips into the water storage tank 11. When the water storage tank 11 is set up alone, the condensate accumulates to a preset height. The industrial mobile air conditioner then issues a full water alarm and stops, and the accumulated condensate in the water storage tank 11 is manually emptied. When the cabinet 1 does not have a water storage tank 11 but a separate drain pump 4 is set up, the condensate drips from the condenser 7 and is collected. When the condensate in the collection box of the drain pump 4 accumulates to a certain height, the drain pump 4 itself starts and discharges the collected condensate from the cabinet 1 through the liquid outlet pipe 5.

[0030] The implementation principle of this application embodiment is as follows: high temperature and high pressure Freon gas flows into condenser 7 from compressor 6 for cooling, thereby forming low temperature and high pressure Freon liquid. At the same time, the heat generated by Freon in condenser 7 is discharged from condenser outlet 17 by condenser fan 10, that is, hot air is discharged from cabinet 1. Then, Freon is fully vaporized in evaporator 8 after being throttled by capillary tube 15. The cooling capacity generated by the refrigerant absorbing heat during vaporization in evaporator 8 is blown out by cold air fan 9 through cold air outlet 3 to achieve cooling of the service area. The condensate from the condenser 7 drips into the water storage tank 11. When the water storage tank 11 is set up alone, after the condensate in the water storage tank 11 accumulates to a predetermined height, the liquid level sensor sends a full water signal to the control terminal. The control terminal controls the compressor 6, the air cooler fan 9, etc. to stop and issues a full water warning for the water storage tank 11. The accumulated condensate in the water storage tank 11 is then manually emptied. When the cabinet 1 is not equipped with a water storage tank 11 but is equipped with a drain pump 4 alone, the condensate drips from the condenser 7 and is collected. After the condensate in the drain pump 4 accumulates to a certain height, the drain pump 4 starts on its own and discharges the collected condensate into the cabinet 1 through the liquid outlet pipe 5. This achieves automatic treatment of the condensate in the air conditioner, saving labor costs, time and effort, and improving drainage efficiency.
