Description

Technical Field

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

[0002] Existing guard booth air conditioners generally use split-type units, requiring the installation of an outdoor unit. If the outdoor unit is mounted on a wall, it places certain weight-bearing requirements on the guard booth wall; if placed directly on the ground, drainage requirements are relatively high. Furthermore, split-type air conditioners are unsuitable for temporary guard booths; frequent installation and removal directly affect the cooling effect, and they are inconvenient to move. Current portable air conditioners are mostly small indoor units; while easy to move, their cooling effect is limited and cannot meet the cooling needs of hot summer weather.

[0003] In view of this, it is necessary to improve the existing air conditioners to solve the above problems. Utility Model Content

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figures 1-6As shown, this utility model discloses a portable and mobile guard booth air conditioner, comprising a shell 1. The top of the shell 1 has an internal circulation air inlet 2, the front side has an internal circulation air outlet 3, and the rear side of the shell 1 has an external circulation air inlet 5 and an external circulation air outlet 6. Each of the internal circulation air inlet 2, internal circulation air outlet 3, external circulation air inlet 5, and external circulation air outlet 6 is equipped with a filter screen. An external circulation air inlet shroud 9 is provided on the external circulation air inlet 5, and an external circulation air outlet shroud 10 is provided on the external circulation air outlet 6. The external circulation air inlet shroud 9 and external circulation air outlet shroud 10 protect the external circulation inlet and outlet, preventing foreign objects, rainwater, etc., from directly entering the shell 1 and affecting the normal operation of the centrifugal fan 19 and condenser 17. A display screen 4 is also provided on the shell 1 above the internal circulation air outlet 3. The display screen 4 is mainly used to display parameters such as temperature, airflow, and mode. Handles 7 are provided on the left and right sides of the shell 1 for easy transport, installation, and maintenance of the air conditioner. The bottom of the outer casing 1 is also provided with feet 11 and wheels 8, and the wheels 8 are equipped with brakes.

[0025] like Figure 5 and Figure 6 As shown, the internal circulation air inlet 2 and the internal circulation air outlet 3 are connected by an internal circulation duct 13. A cross-flow fan 15 is provided at one end of the duct near the internal circulation air inlet 2. An evaporator 12 is arranged circumferentially above the cross-flow fan 15. A heater 21 is provided above the evaporator 12. In this embodiment, there are two heaters 21, arranged in parallel above the evaporator 12. The heaters 21 face the internal circulation air inlet 2 and are located below it. From the internal circulation air inlet 2, the air passes sequentially through the heater 21, the cross-flow fan 15, and the internal circulation duct 13 until it reaches the internal circulation air outlet 3, forming an internal circulation. Figure 5 The red arrows indicate the direction of the internal circulation airflow. A centrifugal fan 19 is installed inside the outer casing 1 at the external circulation inlet 5. The centrifugal fan 19 is fixed to the bottom plate inside the outer casing 1 by a fan bracket 20. A condenser 17 is installed inside the outer casing 1 at the external circulation outlet 6. A guide plate 18 is provided between the centrifugal fan 19 and the condenser 17. The airflow flows from the external circulation inlet 5 through the centrifugal fan 19, the guide plate 18, and the condenser 17 in sequence, and then flows out from the external circulation outlet 6, forming an external circulation. Figure 6 The pink arrow indicates the direction of the external circulation airflow. A compressor 16 is located in front of the condenser 17, and a gas-liquid separator 22 and an electrical box 14 are located on the front side of the compressor 16. The outlet of the compressor 16 is connected to the inlet of the condenser 17 via a pipe. The outlet of the condenser 17 is connected to the inlet of the evaporator 12 via a pipe. The outlet of the evaporator 12 is connected to the inlet of the gas-liquid separator 22 via a pipe. The outlet of the gas-liquid separator 22 is connected to the inlet of the compressor 16 via a pipe.

[0026] like Figure 6As shown, the air guide plate 18 is supported inside the outer shell 1 from top to bottom and is fixed to the outer shell 1 through a connecting plate. The air guide plate 18 is an arc-shaped structure with several ventilation holes, and its arc-shaped concave surface faces the side of the external circulation air inlet 5.

[0027] Working principle:

[0028] In the external circulation mode, a high-volume centrifugal fan 19 is installed inside the external circulation air inlet 5. When the air conditioner starts running, the compressor 16 and the centrifugal fan 19 work, drawing outside air into the outer casing 1 through the centrifugal fan 19 located inside the external circulation air inlet 5. A condenser 17 is installed inside the external circulation air outlet 6. Since the external circulation mode only has two air outlets, the air drawn in from the outside flows towards the external circulation air outlet 6 through the air guide plate 18 and can only be blown out from the external circulation air outlet 6. As it is blown out, it passes through the condenser 17, carrying away the heat of the refrigerant in the condenser 17, lowering the temperature of the refrigerant inside the condenser 17, and blowing hot air out from the external circulation air outlet 6. Using a high-volume centrifugal fan 19 can remove the heat from the condenser 17 more quickly, making the air conditioner's cooling effect more prominent.

[0029] After being cooled, the refrigerant in the condenser 17 enters the internal circulation system through the throttling device.

[0030] In the internal circulation system, an evaporator 12 and a cross-flow fan are installed inside the internal circulation outlet 3. When the air conditioner is running, the cross-flow fan 15 operates, and the air in the internal circulation space, i.e., the internal circulation duct 13, is blown out from the internal circulation outlet 3, creating negative pressure in the internal circulation space. This draws indoor air in through the internal circulation inlet 2 above the outer casing 1. The refrigerant inside the evaporator 12 is cooled and throttled through external circulation, resulting in a temperature lower than the indoor air temperature. The air drawn in from the room passes through the evaporator 12, where the low-temperature refrigerant carries away the heat from the air passing through the evaporator 12, cooling the air and lowering its temperature. Then, the cooled air passes through the internal circulation duct 13 and is blown out from the internal circulation outlet 3, returning to the room, thus completing the heat exchange between the indoor air and the indoor temperature.

[0031] In winter when the temperature is low, heater 21 can be used to heat the internal circulating air to achieve heating. At the same time, heat can be carried to condenser 17 through refrigerant circulation to avoid the phenomenon of ice and frost on the external circulation components.

[0032] Each air inlet and outlet is equipped with a filter screen, which effectively prevents dust and lint from falling onto the evaporator 12 inside the internal circulation air inlet 2. This effectively prevents the evaporator 12 from experiencing a decrease in heat exchange capacity due to dust and lint, and can greatly extend the service life of the air conditioner. Positioning the internal circulation air inlet 2 at the top and the internal circulation air outlet 3 on the side facilitates indoor airflow and rapid cooling, achieving energy-saving effects. Equipped with braked wheels 8 allows the air conditioner to be moved and fixed in place with flexibility.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
