Description

Technical Field

[0001] The present application relates to the technical field of air treatment, and in particular to an air conditioner. Background Art

[0002] Air conditioners condition the indoor air by discharging cooled air obtained through a refrigeration cycle, which involves compression, condensation, expansion, and evaporation of a refrigerant. Alternatively, they discharge heated air obtained through the reverse process, thereby discharging the cooled air into the indoor space. In the cooling / heating cycle, the suction side of the compressor is connected to a low-pressure line, while the discharge side is connected to a high-pressure line. Currently, air conditioners incorporate a bypass line between the high-pressure and low-pressure lines. This bypass line protects the compressor by unloading the compressor when the high-pressure line is too high and bypassing the compressor when the low-pressure line is too low, thereby reducing the suction and exhaust pressure differential.

[0003] Bypass valves balance pressure differentials within air conditioner outdoor units and protect the unit. However, when switching between hot and cold air and reversing the four-way valve in high-capacity air conditioner outdoor units, the large refrigerant pressure differential can cause stress and vibration in the bypass valve and connected piping. This can lead to pipe rupture over extended periods of operation. Fixing the bypass valve is a common practice in the industry to reduce vibration and stress.

[0004] However, existing bypass valve fixing solutions have the following problems: 1. They can only fix the inlet or outlet of the bypass valve, resulting in poor stress improvement; 2. The fixing parts have a complex structure and require mold processing; 3. Installation is inconvenient and production operations are difficult. Utility Model Content

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0045] The compressor compresses low-temperature, low-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0046] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0047] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0048] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0050] The compressor draws in and compresses refrigerant, bringing it to a high-temperature, high-pressure state. The motor's rotational force compresses the low-pressure gaseous refrigerant to a high-pressure state. In other words, the compressor draws in low-pressure gas and discharges high-pressure gas. The piping on the compressor's discharge side is referred to as the high-pressure line 20. The compressor draws in low-temperature, low-pressure gas, and the piping on the compressor's intake side is referred to as the low-pressure line 10.

[0051] The four-way valve 30 guides the refrigerant compressed by the compressor to the outdoor heat exchanger in the cooling mode, and guides the refrigerant compressed by the compressor to the indoor heat exchanger of the indoor unit in the heating mode.

[0059] The air conditioner achieves effective fixation of the low-pressure side branch pipe 401 and the high-pressure side branch pipe 402 of the bypass valve 40 by improving the fixing component 50, avoiding the stress and vibration of the bypass valve 40 and the connected pipeline caused by the impact of excessive refrigerant pressure difference when the outdoor unit of the large-capacity air conditioner is switched between hot and cold and the four-way valve 30 is reversed, ensuring the effective fixation of the bypass valve 40 and effectively solving the problem of excessive stress of the bypass valve 40 of large-capacity units.

Furthermore, a square hole 80 is also provided at the corresponding position of the second plate portion 5013. By providing a square hole 80 at the first bend 50222 (and / or the corresponding position of the second plate portion 5013) corresponding to the thickened portion of the low-pressure side branch pipe 401 of the bypass valve 40, the accommodation space of the thickened portion of the low-pressure side branch pipe 401 of the bypass valve 40 is ensured in the second cavity, and at the same time, sufficient contact points are ensured between the inner wall of the second cavity and the outer wall of most positions of the low-pressure side branch pipe 401 of the bypass valve 40, thereby ensuring that the low-pressure side branch pipe 401 of the bypass valve 40 is in the second cavity. Furthermore, a square hole 80 may be provided at the second bent portion 50232 corresponding to the thickened portion of the high-pressure side branch pipe 40 of the bypass valve 40 to ensure that the thickened portion of the high-pressure side branch pipe 402 of the bypass valve 40 is within the accommodation space of the third cavity. At the same time, sufficient contact points are also ensured between the inner wall of the third cavity and the outer wall of most positions of the high-pressure side branch pipe 402 of the bypass valve 40, thereby ensuring that the high-pressure side branch pipe 402 of the bypass valve 40 is fastened within the third accommodation cavity.
