Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an anti-condensation valve component, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] When the split-type air conditioner is in cooling operation, the stop valve (working valve) of the air conditioner outdoor unit circulates low-temperature refrigerant, which belongs to the low-temperature pipeline. The metal valve bracket assembled with it will also be affected by the cold transfer of the stop valve to reduce the temperature. When the temperature is lower than the atmospheric dew point (dew point refers to the temperature when the air is cooled to saturation under the condition that the water vapor content in the air remains unchanged and the air pressure is kept constant, it is called dew point temperature, abbreviated as dew point, and the unit is expressed in ℃ or ℉), when the water vapor in the air contacts the valve bracket, it is very easy to form condensation water on the wall surface. Since there is a gap between the stop valve cover and the valve bracket, the condensation water is very easy to leak through the gap and drip.

[0003] In order to solve the problem of condensation dripping on the valve bracket, the existing solution is to attach a sponge to the contact surface between the stop valve cover and the valve bracket, or to structurally drain the condensation of the valve bracket into the water collection tank of the stop valve cover, and finally discharge it to the chassis. However, these existing solutions will have problems over time. For example, the sponge may age, deform or lose its water absorption capacity, requiring frequent cleaning, and the water collection tank may also need to be cleaned frequently due to dust accumulation, blockage and other problems, resulting in high maintenance costs.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0034] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0035] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0036] It can be seen from the solutions provided by the prior art that the existing solutions all solve the problem of condensation water dripping after the condensation water is generated on the valve bracket 11, rather than fundamentally solving the problem of condensation water generation on the valve bracket 11. For this reason, the inventor has proposed the following improvement plan after research, and will explain it in detail in the following embodiments.

[0037] See also Figure 1 and Figure 2 The embodiment of the present invention provides an anti-condensation valve assembly, which is applied to the air conditioner outdoor unit 4, and includes: a valve bracket 11, which is arranged on the air conditioner outdoor unit 4; a working valve 12, which is arranged on the valve bracket 11; and a heat transfer component 13, which is arranged on the valve bracket 11. The heat transfer component 13 is used to circulate high-temperature medium and transfer the heat of the high-temperature medium to the valve bracket 11. In this embodiment, the working valve 12 can be arranged on one side of the valve bracket 11, and the heat transfer component 13 can be arranged on the other side of the valve bracket 11. Of course, the working valve 12 and the heat transfer component 13 can also be arranged on the same side of the valve bracket 11 at the same time, as long as the efficiency of heat conduction of the heat transfer component 13 is not affected.

[0038] Since the low-temperature refrigerant continuously circulates inside the working valve 12 during the cooling operation of the air conditioner, and the temperature is usually in the range of 9-14°C, under the effect of the temperature difference, the working valve 12 will quickly transfer the coldness of the low-temperature refrigerant to the valve bracket 11 at room temperature through the contact surface with the valve bracket 11, so that the valve bracket 11 diffuses and cools down around the contact surface until it approaches the temperature of the low-temperature refrigerant. At this time, when the high-temperature water vapor in the air contacts the low-temperature valve bracket 11, it is very easy to form condensation water on the wall surface. After the condensation water is collected, it slides down along the wall surface of the valve bracket 11. In order to solve this problem, in this embodiment, a heat transfer component 13 is provided on the valve bracket 11. The heat transfer component 13 can transfer the heat of the high-temperature medium (such as hot water, steam or heated refrigerant) to the valve bracket 11 through heat conduction or convection, etc., to offset the coldness of the low-temperature refrigerant conducted by the working valve 12, thereby increasing the temperature of the valve bracket 11, and effectively avoiding the formation of condensation water on the valve bracket 11, fundamentally solving the problem of condensation water dripping on the air conditioner outdoor unit 4.

[0039] It should be noted that the working valve 12 only has a switching function, which is used to store the low-temperature refrigerant in the condenser. In the cooling and heating modes, the working valve 12 remains in a fully open state. However, the four-way pipe (also called a four-way reversing valve) connecting the compressor and the condenser is used for the flow direction of the refrigerant, so that the air-conditioning system can switch between the cooling mode and the heating mode. The throttling device controls the refrigerant flow. It reduces the pressure and temperature of the refrigerant by reducing the flow cross-section of the refrigerant or increasing its flow resistance, thereby making it easier for the refrigerant to evaporate and absorb heat in the evaporator. The types of throttling devices include capillary tube assemblies 3, thermal expansion valves, and electronic expansion valves.

[0040] The valve bracket 11 is a structure for supporting and fixing the working valve 12 and the heat transfer component 13, so the valve bracket 11 needs to be firmly arranged on the air conditioner outdoor unit 4. Preferably, the valve bracket 11 is made of corrosion-resistant material, such as stainless steel or aluminum alloy, to ensure that it is not easily damaged during long-term use in harsh outdoor environments.

[0041] Further, such as Figure 3 and Figure 4As shown, the heat transfer assembly 13 includes a heat transfer body 131 and a heat transfer pipe 132 disposed on the heat transfer body 131 for circulating high-temperature medium. The heat transfer body 131 is disposed on the valve bracket 11. In this embodiment, the heat transfer body 131 is responsible for receiving the heat transferred from the heat transfer pipe 132 and further transferring it to the valve bracket 11. In order to enable the heat to be quickly and effectively transferred from the heat transfer pipe 132 to the valve bracket 11, the heat transfer body 131 is preferably made of a material with high thermal conductivity, such as copper, aluminum or its alloy, and in order to better enhance the efficiency of heat exchange between the heat transfer body 131 and the valve bracket 11, the structure of the heat transfer body 131 needs to have a larger thermal contact area with the valve bracket 11, as well as higher mechanical strength.

[0042] It should be noted that the heat transfer body 131 can be rectangular or irregular in shape. For example, the heat transfer body 131 can match the shape of the valve bracket 11, so that the heat transfer body 131 and the valve bracket 11 have a larger contact area and obtain a better heat transfer effect.

[0043] Furthermore, the heat transfer tube 132 also needs to be made of a material with high thermal conductivity and good corrosion resistance and pressure resistance to cope with the influence of high temperature media and the external environment. Therefore, the heat transfer tube 132 is preferably made of copper or stainless steel.

[0044] In a specific embodiment, when the high-temperature medium flows through the heat transfer tube 132, the heat it carries is transferred to the heat transfer body 131 through the wall of the heat transfer tube 132, and the heat transfer body 131 then quickly transfers the heat to the valve bracket 11, so that the wall surface of the valve bracket 11 simultaneously receives the coldness conducted from the working valve 12 and the heat conducted by the heat transfer body 131. After the valve bracket 11 reaches thermal equilibrium, its temperature rises, which can effectively prevent the occurrence of condensation. In this embodiment, through the synergistic effect of the heat transfer tube 132 and the heat transfer body 131, efficient heat transfer can be achieved, ensuring that the temperature of the valve bracket 11 is always kept above the dew point temperature, effectively avoiding the generation of condensation water on the valve bracket 11.

[0045] In this embodiment, the heat transfer tube 132 can be set to be U-shaped, spiral or S-shaped. The spiral heat transfer tube 132 can increase the flow path length of the fluid, thereby extending the residence time of the fluid in the heat transfer tube 132, increasing the heat exchange area, and improving the heat transfer efficiency. At the same time, the spiral shape also helps to generate eddy currents and disturbances, thereby enhancing the heat exchange effect between the fluid and the tube wall. The design of the U-tube allows the fluid to flow back and forth multiple times in the heat transfer tube 132, increasing the contact time and contact area between the fluid and the tube wall, thereby improving the heat transfer efficiency. At the same time, the U-tube also has good structural strength and vibration resistance. Preferably, the heat transfer tube 132 can be set to be S-shaped. The S-shaped heat transfer tube 132 increases the flow path length of the fluid in the limited space of the heat transfer component 13, thereby greatly prolonging the residence time of the fluid in the tube, which helps the fluid to contact the tube wall more fully during the flow process, so that the heat can be more evenly transferred to various parts of the tube wall, thereby improving the uniformity of heat transfer. Since the S-shaped heat transfer tube 132 increases the flow path and contact area of ​​the fluid, the fluid can generate more eddies and disturbances when flowing in the tube. These eddies and disturbances can destroy the boundary layer of the fluid flow, reduce thermal resistance, and thus improve the heat transfer efficiency.

[0046] Specifically, the heat transfer body 131 includes: a first heat transfer member 1311 and a second heat transfer member 1312, one side of the first heat transfer member 1311 is in contact with one side of the valve bracket 11; one side of the second heat transfer member 1312 covers the other side of the first heat transfer member 1311, and an installation space 14 is formed between the first heat transfer member 1311 and the second heat transfer member 1312, and the heat transfer pipe 132 is installed in the installation space 14.

[0047] In this embodiment, one side of the first heat transfer element 1311 contacts one side of the valve support 11, and the first heat transfer element 1311 functions as a heat transfer base, ensuring that heat can be smoothly transferred from the first heat transfer element 1311 to the valve support 11, thereby preventing the valve support 11 and the working valve 12 thereon from generating condensation due to low temperature. One side of the second heat transfer element 1312 covers the other side of the first heat transfer element 1311, and the second heat transfer element 1312 functions as a heat transfer cover plate. An installation space 14 is formed between the first heat transfer element 1311 and the second heat transfer element 1312, and the installation space 14 provides a stable support and positioning for the heat transfer pipe 132, ensuring that the heat transfer pipe 132 can be accurately installed at a predetermined position and maintain a stable working state, and protects the heat transfer pipe 132 from the influence of the external environment, and also ensures that heat can be smoothly transferred along the heat transfer pipe 132 to the first heat transfer element 1311 and the second heat transfer element 1312, and then transferred to the valve support 11.

[0048] The first heat transfer member 1311 can be made of a material with high thermal conductivity, such as copper, aluminum or its alloy, so as to quickly transfer the heat in the heat transfer tube 132 to the valve bracket 11. At the same time, the first heat transfer member 1311 also has good mechanical strength and corrosion resistance to cope with the influence of the external environment. The second heat transfer member 1312 can also be made of a material with high thermal conductivity, such as copper, aluminum or its alloy, and is tightly connected to the first heat transfer member 1311 to prevent heat leakage and the influence of the external environment on the heat transfer process. The tight connection between the first heat transfer member 1311 and the second heat transfer member 1312 can be achieved by a connector 133, such as screw fixing, and can also be achieved by sealing gaskets, welding, etc.

[0049] Specifically, when the high-temperature medium flows through the heat transfer tube 132, the heat it carries is first absorbed by the heat transfer tube 132, and then transferred to the second heat transfer element 1312 and the first heat transfer element 1311 by heat conduction. Then, the heat is transferred to the valve bracket 11 through the first heat transfer element 1311, thereby increasing the temperature of the valve bracket 11 and effectively avoiding the occurrence of condensation on the valve bracket 11.

[0050] Furthermore, an arc groove 15 is provided on the other side of the first heat transfer member 1311 and one side of the second heat transfer member 1312, and the arc grooves 15 of the first heat transfer member 1311 and the second heat transfer member 1312 together constitute the installation space 14. In this embodiment, the design of the two arc grooves 15 provides a space for the heat transfer tube 132 to be positioned in the first heat transfer member 1311 and the second heat transfer member 1312. Since the shape of the heat transfer tube 132 is cylindrical or approximately cylindrical, when the heat transfer tube 132 is placed in the arc groove 15, the heat transfer tube 132 can fit closely to the groove wall, reducing displacement caused by vibration or temperature change, thereby ensuring the stability and reliability of the heat transfer tube 132 during operation.

[0051] In this embodiment, the contact area between the arc groove 15 and the heat transfer tube 132 is larger, which helps to optimize the heat transfer between the heat transfer tube 132 and the heat transfer body 131. Since the curvature of the arc groove 15 matches the shape of the heat transfer tube 132, the heat can be transferred from the heat transfer tube 132 to the heat transfer body 131 more smoothly, reducing the loss and resistance in the heat transfer process. Moreover, the design of the arc groove 15 also helps to enhance the sealing between the heat transfer bodies 131. When the second heat transfer member 1312 is covered on the first heat transfer member 1311, the joint of the two arc grooves 15 can form a tight sealing line to prevent heat leakage and the influence of the external environment on the heat transfer process, thereby further improving the heat transfer efficiency and avoiding the occurrence of condensation.

[0052] Furthermore, the design of the arc groove 15 makes the heat transfer body 131 structure have a certain structural flexibility, which can adapt to heat transfer tubes 132 of different shapes and sizes. In a specific application scenario, by adjusting the curvature and size of the two arc grooves 15, heat transfer tubes 132 of various specifications can be installed and fixed to meet different heat transfer requirements and working conditions. At the same time, the design of the arc groove 15 simplifies the installation and maintenance process of the heat transfer tube 132. During installation, it is only necessary to put the heat transfer tube 132 into the arc groove 15 and fix the second heat transfer member 1312 through the connector 133; during maintenance, the heat transfer tube 132 or the heat transfer body 131 can also be easily disassembled and replaced, reducing the maintenance cost and difficulty.

[0053] In this embodiment, one side of the first heat transfer member 1311 is in plane contact with one side of the valve bracket 11. The plane contact can first ensure that the first heat transfer member 1311 and the valve bracket 11 form a large area of ​​close contact, thereby improving the efficiency of heat transfer from the first heat transfer member 1311 to the valve bracket 11. At the same time, the large area contact reduces the thermal resistance, allowing the heat to flow more smoothly. Secondly, the connection between the first heat transfer member 1311 and the valve bracket 11 is more stable and reliable. Compared with other contact methods (such as curved surface contact), the plane contact can better resist displacement or looseness caused by factors such as vibration and temperature changes, ensuring the stability and reliability of the heat transfer process. Since the plane contact can evenly distribute heat and stress, it helps to reduce the thermal stress caused by temperature changes, thereby protecting the valve bracket 11 and the heat transfer body 131 from thermal stress damage.

[0054] Furthermore, based on the planar contact between one side of the first heat transfer element 1311 and one side of the valve bracket 11, further measures can be taken (such as using a sealing gasket, applying silicone grease or sealant, etc.) to improve the sealing between one side of the first heat transfer element 1311 and one side of the valve bracket 11. Good sealing helps to reduce the gap between the contact surfaces, enhance the heat conduction effect, and prevent heat leakage and the influence of the external environment on the heat transfer process.

[0055] Further, combined with Figure 2 and Figure 5 As shown, one end of the heat transfer tube 132 is connected to the condenser outlet pipe 2, the other end of the heat transfer tube 132 is connected to one end of the capillary tube assembly 3, and the other end of the capillary tube assembly 3 is connected to the working valve 12. In this embodiment, one end of the heat transfer tube 132 is usually connected to the condenser outlet pipe 2 through a flange connection or a dedicated pipe joint, and this connection needs to ensure good sealing to prevent refrigerant leakage.

[0056] In this embodiment, the condenser is an important component in the refrigeration cycle, which is responsible for condensing high-temperature and high-pressure refrigerant vapor into liquid. The other end of the heat transfer tube 132 is connected to one end of the capillary assembly 3. The capillary assembly 3 plays a role in throttling and reducing pressure in the refrigeration system, converting high-pressure refrigerant liquid into low-pressure mist refrigerant to prepare for the subsequent evaporation process. The other end of the capillary assembly 3 is connected to the working valve 12, which is used to further control the flow rate of the refrigerant to adapt to the refrigeration needs under different working conditions. The working valve 12 controls the temperature and pressure of the evaporator by adjusting the flow rate of the refrigerant to ensure that the refrigeration system can operate efficiently and stably.

[0057] In a specific embodiment, a high-temperature medium continuously flows through the outlet pipe 2 of the condenser, and its temperature is about 3-5°C higher than the outdoor ambient temperature, usually in the range of 32-55°C. The high-temperature medium flows through the heat transfer tube 132, and transmits the heat through the tube wall of the heat transfer tube 132 to the heat transfer body 131, and then transmits the heat to the valve bracket 11 through the contact surface between the heat transfer tube 132 and the valve bracket 11 of the heat transfer body 131. At this time, the valve bracket 11 simultaneously receives the cold transferred from the working valve 12 and the heat transferred from the heat transfer component 13. After reaching thermal equilibrium, the temperatures of the valve bracket 11 and the heat transfer body 131 tend to be consistent, and no condensation water is generated on the wall of the valve bracket 11. At the same time, the high-temperature medium in the heat transfer tube 132 absorbs the cold from the cooled heat transfer body 131, and the temperature is further reduced. After throttling by the capillary assembly 3, a lower low-temperature refrigerant can be obtained, and more heat can be absorbed when flowing through the indoor evaporator, thereby improving the refrigeration capacity of the air conditioner. That is to say, in this embodiment, the high-temperature medium flowing in the heat transfer tube 132 comes from the high-temperature refrigerant in the condenser outlet pipe 2. The high-temperature refrigerant is naturally generated by the air conditioner during refrigeration operation. The high-temperature refrigerant needs to be cooled when it flows out of the condenser outlet pipe 2. In this embodiment, the high-temperature refrigerant flowing out of the condenser outlet pipe 2 is first transported to the heat transfer tube 132, and the heat is transferred to the valve bracket 11 through the heat transfer body 131 to cool the valve bracket 11. After the high-temperature refrigerant dissipates heat through the valve bracket 11 and then throttles through the capillary assembly 3, it can obtain a lower low-temperature refrigerant. When it flows through the first working valve 121 and is input into the indoor evaporator, it can absorb more heat, thereby improving the refrigeration capacity of the unit. Therefore, on the whole, this embodiment uses the high-temperature refrigerant that needs to be cooled to cool the valve bracket 11, without increasing additional energy consumption, and fully utilizing the heat. The heat transfer effect is completely spontaneous and adaptable to all working conditions, and it has the characteristics of stable and reliable anti-condensation effect.

[0058] In other embodiments, the valve bracket 11 can also be cooled by using an external high-temperature medium. For example, the heat transfer pipe 132 can use a microchannel heat exchanger or other structure to transmit the high-temperature medium, which is suitable for scenarios where the heat of the high-temperature refrigerant flowing out of the condenser outlet pipe 2 is insufficient.

[0059] It should be noted that Figure 5 The arrows in the figure indicate the flow process of the high-temperature medium in the condenser outlet pipe 2 flowing to the heat transfer component 13, cooling down through the valve bracket 11 with a lower temperature, and then flowing into the capillary component 3.

[0060] Further, such as Figure 6 As shown, the working valve 12 includes a first working valve 121 and a second working valve 122 for transmitting low-temperature refrigerant, the heat transfer component 13 is located between the first working valve 121 and the second working valve 122, and the other end of the capillary component 3 is connected to the first working valve 121.

[0061] In this embodiment, when the air conditioner is in cooling operation, the first working valve 121 and the second working valve 122 both transmit low-temperature refrigerant, and both can transfer the cold of the low-temperature refrigerant to the valve bracket 11. Therefore, the condensation center of the valve bracket 11 is located between the first working valve 121 and the second working valve 122. Therefore, in order to improve the anti-condensation effect of the valve bracket 11, the heat transfer component 13 is arranged between the first working valve 121 and the second working valve 122, so that the heat transfer component 13 can balance the temperature of the valve bracket 11 more quickly.

[0062] After high-temperature and high-pressure refrigerant vapor is discharged from the compressor, it enters the condenser. In the condenser, the refrigerant vapor is cooled and condensed into a high-pressure liquid. The high-temperature refrigerant (high-temperature and high-pressure refrigerant liquid) flows out through the condenser outlet pipe 2 and then enters the heat transfer component 13. The heat transfer component 13 is located between the first working valve 121 and the second working valve 122. The high-temperature refrigerant enters the capillary component 3 after heat dissipation by the heat transfer component 13. The capillary component 3 throttles and reduces the pressure of the high-temperature refrigerant through its channel, so that it changes from a high-pressure state to a low-pressure state, and partially evaporates into a gas-liquid mixture. After passing through the capillary component 3, the refrigerant enters the first working valve 121, which is used to accurately control the refrigerant flow entering the evaporator. By adjusting the opening of the first working valve 121, the refrigerant flow in the air-conditioning system and the temperature of the evaporator can be controlled, thereby affecting the refrigeration performance of the entire air conditioner.

[0063] Furthermore, the heat transfer component 13 further includes a temperature sensor, which can be disposed on the heat transfer tube 132, on the heat transfer body 131, on the valve support 11, or on the heat transfer tube 132, the heat transfer body 131, and the valve support 11. In this embodiment, the temperature sensor is used to detect the temperature near the heat transfer body 131, in the heat transfer tube 132, and around the valve support 11, to ensure a high heat conduction effect.

[0064] Specifically, by detecting the temperature at different positions through the temperature sensor, the temperature sensor can help the system optimize performance. For example, according to the temperature change in the heat transfer tube 132, the flow rate or pressure of the high temperature medium can be adjusted to improve the heat transfer efficiency. At the same time, by comparing the temperature difference between the heat transfer body 131 and the valve bracket 11, the heat transfer efficiency of the system can be evaluated and necessary adjustments can be made accordingly.

[0065] Temperature sensors can also detect abnormal conditions in the air conditioner in a timely manner, such as local overheating, refrigerant leakage, etc. These abnormal conditions are often related to certain faults in the system. Through the detection data of the temperature sensor, technicians can quickly locate the problem and take appropriate measures to repair it.

[0066] If the temperature exceeds the preset safety threshold, the system can automatically take protective measures, such as shutting down the compressor, activating the alarm, etc., to prevent equipment damage or safety accidents.

[0067] Furthermore, the heat transfer component 13 further includes a flow valve, which is disposed on the heat transfer tube 132. In this embodiment, the flow valve can maintain a constant flow through the heat transfer tube 132 when there is a pressure difference change when the heat transfer tube 132 transfers heat.

[0068] Specifically, the flow valve may include a regulating valve group and an automatic balancing valve group. The regulating valve group is used to set the preset flow in the heat transfer tube 132. The automatic balancing valve group is used to automatically adjust the valve opening when the system pressure changes to maintain the preset flow unchanged. During the flow of high-temperature medium in the heat transfer tube 132, due to the high temperature of the medium and the large pressure fluctuations, the flow valve can automatically eliminate the flow deviation caused by these fluctuations to maintain the stability of the flow process. By accurately controlling the flow, the flow valve helps to reduce unnecessary energy loss and improve the effect of heat conduction.

[0069] It should be noted that the manufacturing materials of the flow valve need to be able to withstand the erosion of high-temperature media and the influence of high-temperature environments to ensure its long-term stable operation. Under high temperatures, the sealing performance of the medium is easily affected, and the flow valve needs to have a good sealing structure to prevent medium leakage. The installation of the flow valve is relatively simple and can be installed vertically or horizontally on the pipeline according to actual conditions.
