Description

Technical Field

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

[0002] With the rapid development of the construction industry and people's increasing requirements for indoor environmental comfort, traditional single-function air-conditioning equipment has gradually become unable to meet the complex and changing air treatment needs.

[0003] Combined air conditioners integrate multiple air handling functional sections that can be flexibly combined and configured according to actual needs, improving the efficiency and accuracy of air handling and enhancing the adaptability and flexibility of the system. Water-cooled combined air conditioners pass hot water through a heat exchanger (e.g., a coil), which transfers heat to the air outside the heat exchanger through the flow of hot water within the heat exchanger.

[0004] However, in winter when the temperature is low, the outdoor air temperature is low, which can cause the water in the heat exchanger to freeze, thereby causing the heat exchanger to be damaged and the air conditioner to be unable to operate normally. Utility Model Content

[0005] The present application provides an air conditioner for solving the problem that when the outdoor air temperature is low, water in a heat exchanger is frozen, causing the heat exchanger to be damaged by frost.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] The present application provides an air conditioner, which may include a housing, a heat exchanger, and a heat exchange assembly. An air inlet channel is formed within the housing, and the housing is provided with an air outlet and an air inlet connected to the air inlet channel. The air inlet is used to communicate with outdoor air. The heat exchanger is disposed within the air inlet channel and is located on the air outlet side of the air inlet and the windward side of the air outlet. The heat exchange assembly includes a condenser and an evaporator. The condenser is disposed within the air inlet channel and is located on the windward side of the heat exchanger. The evaporator is disposed on the air outlet side of the heat exchanger. The condenser is provided within the air inlet channel and is provided on the windward side of the heat exchanger. The evaporator is provided within the air outlet side of the heat exchanger. The condenser has a first heat exchange channel disposed within the condenser, and a second heat exchange channel disposed within the evaporator. The first heat exchange channel is connected to the second heat exchange channel, and is used to circulate refrigerant in the first heat exchange channel and the second heat exchange channel.

[0008] Since the condensation part is arranged on the windward side of the heat exchanger, the refrigerant in the first heat exchange channel can be condensed under the action of the cold air entering from the air inlet, and the refrigerant can release heat during condensation. In this way, the air can absorb the heat released by the refrigerant during condensation in the condensation part, so that the temperature of the air flowing to the heat exchanger is increased relative to the outdoor air, thereby preventing the water in the heat exchanger from freezing under the action of the cold air.

[0009] Furthermore, because the evaporator is located on the outlet side of the heat exchanger, the temperature of the air flowing out after heat exchange through the heat exchanger is relatively high. This allows the refrigerant in the second heat exchange channel to exchange heat with the air and evaporate into a gaseous refrigerant. Since the first and second heat exchange channels are connected, the gaseous refrigerant can flow into the first heat exchange channel of the condenser, where it condenses into liquid refrigerant. This liquid refrigerant then flows back into the second heat exchange channel of the evaporator. This creates a refrigerant circulation loop, continuously delivering refrigerant to the first heat exchange channel to exchange heat with the cold air entering the air inlet.

[0010] In some embodiments of the present application, the condenser unit may include a first heat exchange pipeline having a first heat exchange channel disposed therein, and a first opening and a second opening disposed therein, communicating with the first heat exchange channel. The evaporator unit may include a second heat exchange pipeline having a second heat exchange channel disposed therein, and a third opening and a fourth opening disposed therein, communicating with the second heat exchange channel. The first opening communicates with the third opening, and the second opening communicates with the fourth opening.

[0011] In this way, the gaseous refrigerant in the first heat exchange pipe of the condensation unit exchanges heat with the outdoor air, condensing into liquid refrigerant. This liquid refrigerant then passes through the second opening and the fourth opening and enters the second heat exchange pipe. The liquid refrigerant in the second heat exchange pipe exchanges heat with the air flowing out of the heat exchanger, evaporating into gaseous refrigerant. This gaseous refrigerant then passes through the third opening and the first opening and enters the first heat exchange pipe to continue condensing. In this way, the first and second heat exchange pipes form a refrigerant circulation loop.

[0012] In some embodiments of the present application, the heat exchange assembly may further include heat exchange fins, which are provided on the first heat exchange pipeline and the second heat exchange pipeline, and the heat exchange fins are thermally conductive with the first heat exchange pipeline and the second heat exchange pipeline.

[0013] In this way, since the heat exchange fins are thermally connected to the first heat exchange pipeline and the second heat exchange pipeline, when air flows through the first heat exchange pipeline and the second heat exchange pipeline, the heat in the first heat exchange pipeline and the second heat exchange pipeline can be transferred to the heat exchange fins, and heat exchange can be carried out when the air contacts the outer walls and heat exchange fins in the first heat exchange pipeline and the second heat exchange pipeline. In this way, the heat exchange fins can expand the heat exchange area between the heat exchange component and the air, thereby improving the heat exchange efficiency of the heat exchange component.

[0014] In some embodiments of the present application, the first heat exchange pipeline may include a heat exchange sub-tube and a bent sub-tube, wherein the heat exchange sub-tube includes a first heat exchange sub-tube, a second heat exchange sub-tube and a third heat exchange sub-tube arranged at intervals along the first direction, and the bent sub-tube includes a first bent sub-tube and a second bent sub-tube.

[0015] The first bent sub-tube is connected between the first heat exchange sub-tube and the second heat exchange sub-tube, the second bent sub-tube is connected between the second heat exchange sub-tube and the third heat exchange sub-tube, and the first bent sub-tube and the second bent sub-tube are located on opposite sides of the heat exchange sub-tube.

[0016] In this way, in the condensation section, under the same spatial conditions, the length of the first heat exchange pipeline can be ensured to be long enough, thereby ensuring a larger contact area between the first heat exchange pipeline and the air, thereby improving the heat exchange efficiency of the condensation section.

[0017] In some embodiments of the present application, the heat exchange fins include a plurality of first heat exchange fins, and the plurality of first heat exchange fins are connected to the heat exchange sub-tubes along a first direction.

[0018] Because the heat exchange sub-tubes are spaced apart along the first direction, and the multiple first heat exchange fins are connected to the heat exchange sub-tubes along the first direction, the first heat exchange fins intersect the multiple heat exchange sub-tubes, thereby simultaneously thermally connecting one first heat exchange fin to multiple heat exchange sub-tubes. In this way, as the refrigerant exchanges heat with the air while flowing along the first heat exchange pipeline, heat loss may occur in the refrigerant. The simultaneous thermal connection of one first heat exchange fin to the multiple heat exchange sub-tubes evenly distributes heat across the multiple heat exchange sub-tubes, thereby improving the heat exchange effect between the air and the heat exchange sub-tubes.

[0019] At the same time, the first heat exchange fins are provided in plurality, which further increases the heat exchange area between the air and the refrigerant in the heat exchange sub-tube, and further improves the heat exchange efficiency between the air and the refrigerant.

[0020] In some embodiments of the present application, the air conditioner may further include a heating device. The air conditioner may further include a heating device, which is located on the air outlet side of the condensation part and on the air inlet side of the heat exchanger. The heating device is used to heat the air flowing out of the condensation part.

[0021] In this way, the heating device can reheat the air after heat exchange in the condensation part, so that the temperature of the air flowing into the heat exchanger increases, further preventing the heat exchanger from being damaged by freezing of water in the heat exchanger.

[0022] In some embodiments of the present application, the air conditioner may further include a temperature sensor and a controller. The temperature sensor is located on the windward side of the heating device and on the air outlet side of the condensation part. The controller is electrically connected to the heating device and the temperature sensor.

[0023] The temperature sensor detects the temperature of the air flowing out of the condenser and sends the current temperature to the controller, which controls the start and stop of the heating device. This allows the air conditioner to determine whether the air flowing out of the condenser will freeze the water in the heat exchanger based on the temperature of the air flowing out of the condenser, and thus controls the start or stop of the heating device. This prevents damage to the heat exchanger due to freezing water in the heat exchanger and effectively reduces the air conditioner's energy consumption.

[0024] In some embodiments of the present application, the air conditioner may further include a connecting pipe, wherein the connecting pipe and the heat exchange assembly are arranged perpendicularly to the arrangement direction of the condenser and the evaporator. The connecting pipe includes a first connecting pipe and a second connecting pipe, wherein the first connecting pipe is connected between the first opening and the third opening, and the second connecting pipe is connected between the second opening and the fourth opening.

[0025] Since the arrangement direction of the connecting pipe and the heat exchange component is perpendicular to the arrangement direction of the condensing part and the evaporating part, the connecting pipe can be set at one end of the condensing part and the evaporating part, thereby saving the space layout requirement of the connecting pipe.

[0026] In this way, the gaseous refrigerant in the condensing section exchanges heat with the outdoor air, condensing into liquid refrigerant. This liquid refrigerant then passes through the second opening, the second connecting pipe, and the fourth opening to enter the evaporating section. The liquid refrigerant in the evaporating section then exchanges heat and evaporates into gaseous refrigerant. This gaseous refrigerant then passes through the third opening, the first connecting pipe, and the first opening to enter the condensing section to continue condensing. In this way, the refrigerant circulates through the condensing section and evaporating section, completing the process of preheating the air entering the heat exchanger.

[0027] In some embodiments of the present application, the air conditioner may further include a protective shell, wherein at least a portion of the connecting pipeline is disposed within the protective shell. In this way, the protective shell may be used to fix and protect the connecting pipeline.

[0028] The present application also provides an air conditioner, which may include a housing, a heat exchanger, and a heat exchange assembly. The housing has an air inlet channel formed therein, and is provided with an air outlet and an air inlet connected to the air inlet channel. The heat exchanger is located on the outlet side of the air inlet and the windward side of the air outlet. The heat exchange assembly includes a condenser and an evaporator, the condenser being located on the windward side of the heat exchanger and the evaporator being located on the outlet side of the heat exchanger. The condenser has a first heat exchange channel formed therein, and the evaporator has a second heat exchange channel formed therein. The first heat exchange channel is connected to the second heat exchange channel, and is configured to allow refrigerant to circulate in the first and second heat exchange channels.

[0029] Since the condensation part is arranged on the windward side of the heat exchanger, the refrigerant in the first heat exchange channel can be condensed under the action of the cold air entering from the air inlet, and the refrigerant can release heat during condensation. In this way, the air can absorb the heat released by the refrigerant during condensation in the condensation part, so that the temperature of the air flowing to the heat exchanger is increased relative to the outdoor air, thereby preventing the water in the heat exchanger from freezing under the action of the cold air.

[0030] In addition, the evaporator is located on the outlet side of the heat exchanger. The refrigerant in the second heat exchange channel can exchange heat with the air flowing out of the heat exchanger, evaporating into a gaseous refrigerant. Because the first and second heat exchange channels are connected, the gaseous refrigerant can flow into the first heat exchange channel, condense into liquid refrigerant in the condenser, and then flow back into the second heat exchange channel. In this way, the refrigerant forms a circulation loop, continuously supplying refrigerant to the first heat exchange channel to exchange heat with the cold air entering the air inlet.

[0052] With the rapid development of the construction industry and people's increasing requirements for indoor environmental comfort, modular air conditioners have been widely used in large commercial buildings, industrial plants and high-end residences due to their modular design, flexible configuration and high efficiency.

[0053] Combined air conditioners integrate multiple air handling functional sections that can be flexibly combined and configured according to actual needs, improving air handling efficiency and accuracy, and enhancing the system's adaptability and flexibility. In combined air conditioners, the heat exchanger (e.g., coil) is a key link in heat exchange, and its performance and stability directly affect the overall operation of the air conditioner.

[0054] Combined air conditioners transfer heat to the air outside the heat exchanger by circulating hot water within it. However, in cold winter regions, when the outdoor air temperature is low, the water in the heat exchanger can easily freeze, causing the heat exchanger to freeze and the air conditioner to stop functioning properly.

[0055] Based on this, an embodiment of the present application provides an air conditioner, which can preheat the air entering the heat exchanger by arranging a preheating device on the windward side of the heat exchanger, so that the air temperature is higher than the freezing point of water, thereby preventing the water in the heat exchanger from freezing due to the low air temperature, and further preventing the heat exchanger from being damaged by freezing.

[0056] Please refer to Figure 1 , Figure 1 This is one of the structural schematic diagrams of an air conditioner 100 provided in an embodiment of the present application. The air conditioner 100 may include a shell 10, a heat exchanger 20 and a heat exchange assembly 30.

[0057] Please refer to Figure 2 , Figure 2 This is a structural schematic diagram of a shell 10 provided in an embodiment of the present application. An air inlet channel 11 is formed in the shell 10, and an air outlet 12 and an air inlet 13 connected to the air inlet channel 11 are provided on the shell 10. The air inlet 13 is used to communicate with outdoor air.

[0058] In one possible structural design, the housing 10 may include a first housing 101 and a second housing 102. A first air inlet channel 111 is formed in the first housing 101, and a second air inlet channel 112 is formed in the second housing 102. The first air inlet channel 111 and the second air inlet channel 112 are connected, and the first air inlet channel 111 and the second air inlet channel 112 constitute at least part of the air inlet channel 11. An air inlet 13 is provided on the first housing 101, and the air inlet 13 is connected to the first air inlet channel 111. An air outlet 12 is provided on the second housing 102, and the air outlet 12 is connected to the second air inlet channel 112.

[0059] In this way, the air inlet 13 and the air outlet 12 can be respectively arranged on different shells, and different shells can be installed in different positions, so that the positions of the air inlet and outlet can be flexibly adjusted according to the actual needs of the user, and air conditioning can be achieved efficiently.

[0060] Please continue to refer to Figure 1 The heat exchanger 20 is disposed in the air inlet channel 11 and is located on the air outlet side of the air inlet 13 and the windward side of the air outlet 12 .

[0061] Please refer to Figure 3 , Figure 3This is a schematic diagram of the structure of a heat exchanger 20 provided in an embodiment of the present application. In the air conditioner 100, the heat exchanger 20 can be a coil. The heat exchanger 20 can include a water inlet 21, a water outlet 22, and a water pipeline. The water inlet 21 can be connected to a hot water pipeline. The hot water in the hot water pipeline flows into the water pipeline through the water inlet 21. The hot water exchanges heat with the air flowing through the heat exchanger 20 and transfers heat to the air outside the water pipeline. In this way, the temperature of the air increases, the temperature of the hot water in the water pipeline decreases, and the water after heat exchange is discharged through the water outlet 22. The hot water pipeline can be a hot water pipeline for municipal heating, a hot water pipeline for a solar heater, or a hot water pipeline for an electric water heater, and this application does not further limit this.

[0062] Please continue to refer to Figure 1 and Figure 4 , Figure 4 for Figure 1 As shown in the second structural diagram of the air conditioner 100, the heat exchange component 30 may include a condensation part 31 and an evaporation part 32. The condensation part 31 is arranged in the air inlet channel 11 and on the windward side of the heat exchanger 20, and the evaporation part 32 is arranged on the air outlet side of the heat exchanger 20.

[0063] Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of a heat exchange component 30 provided in an embodiment of the present application. A first heat exchange channel 311 is provided in the condensation portion 31, and a second heat exchange channel 321 is provided in the evaporation portion 32. The first heat exchange channel 311 is connected to the second heat exchange channel 321, so that the refrigerant can circulate in the first heat exchange channel 311 and the second heat exchange channel 321 to form a refrigerant circulation loop.

[0064] Since the condensation section 31 is arranged on the windward side of the heat exchanger 20, the refrigerant in the first heat exchange channel 311 can be condensed under the action of the cold air entering from the air inlet 13, and the refrigerant can release heat during condensation. In this way, the air can absorb the heat released by the refrigerant during condensation in the condensation section 31, so that the temperature of the air flowing to the heat exchanger 20 is increased relative to the outdoor air, thereby preventing the water in the heat exchanger 20 from freezing under the action of the cold air.

[0065] In addition, since the evaporation portion 32 is arranged on the air outlet side of the heat exchanger 20, the refrigerant in the second heat exchange channel 321 can absorb heat and evaporate, and the temperature of the air flowing out after heat exchange through the heat exchanger 20 is relatively high. In this way, the refrigerant in the second heat exchange channel 321 can exchange heat with the air, absorb the heat of the air, and thus evaporate into a gaseous refrigerant.

[0066] Since the first heat exchange channel 311 and the second heat exchange channel 321 are connected, the gaseous refrigerant can flow to the first heat exchange channel 311 of the condensation section 31, condense into liquid refrigerant in the condensation section 31, and then the liquid refrigerant flows back to the second heat exchange channel 321 of the evaporation section 32. In this way, the refrigerant forms a circulation loop, continuously transporting the refrigerant to the first heat exchange channel 311 to exchange heat with the cold air entering from the air inlet 13.

[0067] It can be understood that the function of the evaporation section 32 is to convert the liquid refrigerant in the second heat exchange channel 321 into gaseous refrigerant, thereby forming a refrigerant circulation loop with the refrigerant in the first heat exchange channel 311 in the condensation section 31, and does not affect the temperature of the air flowing into the heat exchanger 20.

[0068] Therefore, in a possible structural design, the condensation section 31 can be arranged in the air inlet channel 11 and located on the air outlet side of the heat exchanger 20, so that the air flowing out of the heat exchanger 20 evaporates the refrigerant.

[0069] In another possible structural design, the condensation portion 31 may also be disposed outside the air inlet channel 11 , which is not further limited in this application.

[0070] Please refer to Figure 6 , Figure 6 for Figure 1 In the third structural diagram of the air conditioner 100 shown in FIG. 1 , in some embodiments of the present application, the condensing portion 31 may include a first heat exchange pipe 312 having a first heat exchange channel 311 disposed therein and having a first opening 313 and a second opening 314 disposed therein, both communicating with the first heat exchange channel 311. The evaporating portion 32 may include a second heat exchange pipe 322 having a second heat exchange channel 321 disposed therein and having a third opening 323 and a fourth opening 324 disposed therein, both communicating with the second heat exchange channel 321. The first opening 313 communicates with the third opening 323, and the second opening 314 communicates with the fourth opening 324.

[0071] In this way, the gaseous refrigerant in the first heat exchange pipe 312 of the condenser 31 exchanges heat with the outdoor air, condensing into liquid refrigerant. The liquid refrigerant then flows downward, passing through the second opening 314 and the fourth opening 324 in sequence and entering the second heat exchange pipe 322. The liquid refrigerant in the second heat exchange pipe 322 exchanges heat with the air flowing out of the heat exchanger 20, evaporating into gaseous refrigerant. The gaseous refrigerant then diffuses upward, passing through the third opening 323 and the first opening 313 in sequence and entering the first heat exchange pipe 312 to continue condensing. In this way, the first heat exchange pipe 312 and the second heat exchange pipe 322 form a refrigerant circulation loop.

[0072] In some embodiments of the present application, the heat exchange assembly 30 may further include heat exchange fins 33, which are arranged on the first heat exchange pipeline 312 and the second heat exchange pipeline 322, and the heat exchange fins 33 are thermally conductive with the first heat exchange pipeline 312 and the second heat exchange pipeline 322.

[0073] In this way, since the heat exchange fins 33 are thermally conductive with the first heat exchange pipeline 312, when air flows through the first heat exchange pipeline 312, the heat in the first heat exchange pipeline 312 can be transferred to the heat exchange fins 33, and heat exchange can be carried out when the air contacts the outer wall of the first heat exchange pipeline 312 and the heat exchange fins 33.

[0074] Similarly, since the heat exchange fins 33 are thermally conductive with the second heat exchange pipe 322, when air flows through the second heat exchange pipe 322, the heat of the air can be transferred directly to the refrigerant through the outer wall of the second heat exchange pipe 322, or it can be transferred to the second heat exchange pipe 322 through the heat exchange fins 33, and then transferred to the refrigerant.

[0075] In this way, the heat exchange fins 33 can increase the heat exchange area of ​​the heat exchange assembly 30, thereby improving the heat exchange efficiency of the heat exchange assembly 30.

[0076] It is understood that in some embodiments of the present application, the heat exchanger 20 may also include heat exchange fins, which are disposed on the water pipe and thermally connected to the water pipe. In this way, due to the thermal connection between the heat exchange fins and the water pipe, when air flows through the heat exchanger 20, heat in the water pipe can be transferred to the heat exchange fins. Heat can be exchanged between the air, the outer wall of the water pipe, and the heat exchange fins when the air contacts them. In this way, the heat exchange fins can expand the heat exchange area, thereby improving heat exchange efficiency.

[0077] Please refer to Figure 7 , Figure 7 for Figure 6 The partial structural schematic diagram of the air conditioner 100 shown in the figure, in some embodiments of the present application, the first heat exchange pipeline 312 may include a heat exchange sub-tube 312A and a bent sub-tube 312B, wherein the heat exchange sub-tube 312A includes a first heat exchange sub-tube 3121, a second heat exchange sub-tube 3122 and a third heat exchange sub-tube 3123 spaced apart along the first direction, and the bent sub-tube 312B includes a first bent sub-tube 3124 and a second bent sub-tube 3125.

[0078] The first bent sub-tube 3124 is connected between the first heat exchange sub-tube 3121 and the second heat exchange sub-tube 3122, and the second bent sub-tube 3125 is connected between the second heat exchange sub-tube 3122 and the third heat exchange sub-tube 3123, and the first bent sub-tube 3124 and the second bent sub-tube 3125 are located on opposite sides of the heat exchange sub-tube 312A.

[0079] In this way, in the condensation section 31, under the same spatial conditions, the length of the first heat exchange pipeline 312 can be ensured to be long enough, thereby ensuring that the contact area between the first heat exchange pipeline 312 and the air is large, thereby improving the heat exchange efficiency of the condensation section 31.

[0080] In some embodiments, the second heat exchange pipe 322 can be arranged in the same manner as the first heat exchange pipe 312. In this way, in the evaporation section 32, under the same spatial conditions, the length of the second heat exchange pipe 322 can be ensured to be sufficiently long, thereby ensuring a larger contact area between the second heat exchange pipe 322 and the air, thereby improving the heat exchange efficiency of the evaporation section 32.

[0081] In some embodiments, the water pipe in the heat exchanger 20 can be arranged in the same manner as the first heat exchange pipe 312. In this way, in the heat exchanger 20, under the same spatial conditions, the length of the water pipe can be ensured, thereby ensuring a larger contact area between the water pipe and the air, thereby improving the heat exchange efficiency of the evaporation section 32.

[0082] In some embodiments of the present application, the heat exchange fins 33 include a plurality of first heat exchange fins 331 , and the plurality of first heat exchange fins 331 are connected to the heat exchange sub-tube 312A along a first direction.

[0083] Since the heat exchange sub-tubes 312A are arranged at intervals along the first direction, multiple first heat exchange fins 331 are connected to the heat exchange sub-tubes 312A along the first direction, so that the first heat exchange fins 331 and the multiple heat exchange sub-tubes 312A intersect, so that one first heat exchange fin 331 is thermally conductive with multiple heat exchange sub-tubes 312A at the same time.

[0084] In this way, since the refrigerant exchanges heat with the air during its flow along the first heat exchange pipeline 312, the refrigerant will suffer heat loss. A first heat exchange fin 331 is thermally conductive with multiple heat exchange sub-tubes 312A at the same time, so that the heat of the multiple heat exchange sub-tubes 312A can be evenly distributed, thereby improving the heat exchange effect between the air and the heat exchange sub-tubes 312A.

[0085] At the same time, the first heat exchange fins 331 are provided in plurality, which further increases the heat exchange area between the air and the refrigerant in the heat exchange sub-tube 312A, and further improves the heat exchange efficiency between the air and the refrigerant.

[0086] Optionally, multiple first heat exchange fins 331 can be arranged vertically with the heat exchange sub-tube 312A. In this way, the overlapping area between the heat exchange sub-tube 312A and the first heat exchange fins 331 can be minimized, thereby maximizing the contact area between the air and the heat exchange sub-tube 312A and the first heat exchange fins 331, thereby improving the heat exchange efficiency of the heat exchange assembly 30.

[0087] When the outdoor air temperature is extremely low, the air entering the air inlet 13 is still at a temperature lower than the freezing point of the hot water flowing into the water pipe of the heat exchanger 20 after being heat exchanged by the refrigerant in the first heat exchange pipe 312 of the condensation section 31. That is to say, the air flowing out after being preheated by the condensation section 31 may still cause the water in the water pipe to freeze, thereby causing the heat exchanger 20 to be damaged by freezing.

[0088] Based on this, please refer to Figure 8 , Figure 8 for Figure 1 The fourth structural diagram of the air conditioner 100 is shown. In some embodiments of the present application, the air conditioner 100 may further include a heating device 40. The air conditioner 100 may further include a heating device 40. The heating device 40 is located on the air outlet side of the condensation section 31 and on the air inlet side of the heat exchanger 20. The heating device 40 is used to heat the air flowing out of the condensation section 31.

[0089] In this way, the heating device 40 can reheat the air after heat exchange in the condensation part 31, so that the temperature of the air flowing into the heat exchanger 20 increases, further preventing the heat exchanger 20 from being damaged by freezing due to the freezing of water in the heat exchanger 20.

[0090] In one possible structural design, the heating device 40 can be an electric heating tube, which can include a shell, a film, a heating wire and a connector. By supplying power to the electric heating tube, the heating wire can convert electrical energy into thermal energy, generate heat, and thus heat the air flowing through the electric heating tube.

[0091] In another possible structural design, the heating device 40 may also be a heating plate, an electromagnetic heating device or an infrared heating device, which is not further limited in this application.

[0092] It is understood that the heating device 40 can reheat the air flowing out of the condensing section 31 to ensure that the temperature of the air entering the heat exchanger 20 is maintained at a relatively high temperature, thereby preventing the water in the heat exchanger 20 from freezing. However, when the air entering the air inlet 13 can prevent the water in the heat exchanger 20 from freezing after being heat-exchanged by the refrigerant in the first heat exchange pipeline 312, keeping the heating device 40 on will increase the energy consumption of the air conditioner.

[0093] Please refer to Figure 9 , Figure 9 for Figure 1 As shown in the fifth structural diagram of the air conditioner 100, in some embodiments of the present application, the air conditioner 100 may also include a temperature sensor 50 and a controller. The temperature sensor 50 is located on the windward side of the heating device 40 and on the air outlet side of the condensation section 31. The controller is electrically connected to the heating device 40 and the temperature sensor 50, and is used to control the start and stop of the heating device 40.

[0094] The temperature sensor 50 can be used to detect the temperature of the air flowing out of the condensation section 31 and send the detected current temperature value to the controller. After receiving the current temperature value, the controller compares it with the preset temperature value. If the current temperature value is less than or equal to the preset temperature value, the controller controls the heating device 40 to start; if the current temperature value is greater than the preset temperature value, the controller controls the heating device 40 to stop working.

[0095] In this way, the air conditioner 100 can judge whether the air at this time can freeze the water in the heat exchanger 20 based on the temperature of the air flowing out of the condensation part 31, and thus control the start or stop of the heating device 40, so as to avoid the heat exchanger 20 being damaged due to the freezing of water in the heat exchanger 20, and effectively reduce the energy consumption of the air conditioner 100.

[0096] For example, the preset temperature value can be the freezing point of water in the heat exchanger 20, or can be higher than the freezing point of water in the heat exchanger 20. The preset temperature value can be selected according to the specific actual situation and is not further limited in this application. Optionally, the preset temperature value can be 0°C, 0.5°C, 1°C, or 2°C.

[0097] In the embodiments provided herein, the controller refers to a device that can generate an operation control signal based on an instruction opcode and a timing signal to instruct the air conditioner 100 to execute a control instruction. For example, the controller can be a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a programmable logic device (PLD), a microprocessor, a microcontroller, or any combination thereof. The controller can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not impose any restrictions on this.

[0098] In some embodiments, the controller may be a microcontroller unit (MCU). An MCU, also known as a single-chip microcomputer or single-chip microcomputer, is a chip that reduces the frequency and specifications of a central processing unit (CPU) and integrates memory, timers, USB, A / D converters, UARTs, PLCs, DMA, and other peripheral interfaces, as well as LCD driver circuits, onto a single chip, forming a chip-level computer capable of providing diverse control combinations for different applications.

[0099] In addition, the controller can be used to control the operation of various components inside the air conditioner 100, so that the various components of the air conditioner 100 can operate to achieve various predetermined functions of the air conditioner 100.

[0100] Please continue to refer to Figure 6 and Figure 10 , Figure 10 for Figure 1 In the sixth structural diagram of the air conditioner 100 shown in FIG. 1 , in some embodiments of the present application, the air conditioner 100 may further include a connecting pipe 60. The connecting pipe 60 and the heat exchange assembly 30 are arranged perpendicularly to the arrangement direction of the condenser 31 and the evaporator 32. The connecting pipe 60 may include a first connecting pipe 601 and a second connecting pipe 602. The first connecting pipe 601 is connected between the first opening 313 and the third opening 323, and the second connecting pipe 602 is connected between the second opening 314 and the fourth opening 324.

[0101] Since the arrangement direction of the connecting pipe 60 and the heat exchange component 30 is perpendicular to the arrangement direction of the condensation section 31 and the evaporation section 32, the connecting pipe 60 can be set at one end of the condensation section 31 and the evaporation section 32, thereby saving the space layout requirement of the connecting pipe 60.

[0102] In this way, the gaseous refrigerant in the condenser section 31 exchanges heat with the outdoor air and condenses into liquid refrigerant. This liquid refrigerant then passes through the second opening 314, the second connecting pipe 602, and the fourth opening 324 to enter the evaporator section 32. The liquid refrigerant in the evaporator section 32 exchanges heat and evaporates into gaseous refrigerant. This gaseous refrigerant then passes through the third opening 323, the first connecting pipe 601, and the first opening 313 to enter the condenser section 31 and continue to condense. In this way, the refrigerant circulates in the condenser section 31 and the evaporator section 32, completing the process of preheating the air entering the heat exchanger 20.

[0103] In some embodiments of the present application, the air conditioner 100 may further include a protective shell 61 , and at least a portion of the connecting pipe 60 is disposed in the protective shell 61 .

[0104] Since at least a portion of the connecting pipe 60 is disposed in the protective shell 61 , the protective shell 61 can be used to fix and protect the connecting pipe 60 .

[0105] In some embodiments, the protective shell 61 may include a fifth opening, a sixth opening, a seventh opening and an eighth opening, so that one end of the first connecting pipe 601 is connected to the first opening 313 through the fifth opening, the other end of the first connecting pipe 601 is connected to the third opening 323 through the sixth opening, one end of the second connecting pipe 602 is connected to the second opening 314 through the seventh opening, and the other end of the second connecting pipe 602 is connected to the fourth opening 324 through the eighth opening.

[0106] Please refer to Figure 11 , Figure 11 for Figure 1 As shown in the seventh structural diagram of the air conditioner 100 , in some embodiments of the present application, the air conditioner 100 may further include a filter 70 , which is arranged in the air inlet channel 11 and located between the air inlet 13 and the condensation portion 31 .

[0107] In this way, the filter 70 can filter out dust particles in the outdoor air, making the air entering the room cleaner and improving the user experience. At the same time, the filter 70 can filter out dust particles in the air to prevent dust from clogging the heat exchanger 20, thereby improving heat exchange efficiency and extending the service life of the heat exchanger 20.

[0108] Please refer to Figure 12 , Figure 12 for Figure 1 As shown in the eighth structural diagram of the air conditioner 100 , in some embodiments of the present application, the air conditioner 100 may further include a blower 80 , which is arranged in the air inlet channel 11 and located between the evaporation portion 32 and the air outlet 12 .

[0109] In this way, the blower 80 can transport air from the air outlet side of the evaporation portion 32 to the air outlet 12, thereby ensuring the flow direction of the air and preventing the backflow of high-temperature air, which reduces the working efficiency of the air conditioner 100.
