Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a dual-evaporation temperature air conditioner and an air intake control method for the air conditioner. Background Technology

[0002] Dual-temperature air conditioning units have certain advantages in both capacity and energy efficiency compared to conventional single-temperature air conditioning units. However, due to the dual-temperature flow path design of the indoor heat exchanger, significant differences in refrigerant temperature can easily occur in the different branches of the indoor heat exchanger. This phenomenon can easily lead to uneven air temperature after passing through the indoor heat exchanger. The hot and humid air mixes with the cold and humid air at the indoor unit's fan blades, forming tiny water droplets. These droplets are then flung by the fan blades to the indoor unit's sweeping blades, air guides, and even the indoor unit's air outlet, ultimately causing condensation and water blowing phenomena in the indoor unit.

[0003] The scheme of adjusting the refrigerant flow distribution by using multiple electronic expansion valves can easily lead to increased noise in the indoor unit. Moreover, one electronic expansion valve can only adjust the refrigerant flow distribution between two branches. Multi-flow indoor heat exchangers require multiple expansion valves for adjustment, which will increase the design cost and indoor unit size accordingly. Summary of the Invention

[0004] To overcome the problem of inconsistent air temperature after passing through the indoor heat exchanger in dual-evaporation temperature air conditioners, where hot and humid air mixes with cold and humid air at the indoor unit's fan blades, forming fine water droplets, which are then flung by the fan blades to the indoor unit's sweeping blades, air guides, and even the indoor unit's air outlet, ultimately causing condensation and water blowing problems, this invention proposes a dual-evaporation temperature air conditioner and an air intake control method for the air conditioner. By using a temperature sensor to detect the refrigerant temperature in each branch of the heat exchanger and adjusting the air intake angle of the air intake components according to the refrigerant temperature in each branch, the problem of uniformity of refrigerant outlet temperature and temperature difference at the outlet can be effectively improved.

High-temperature, high-humidity air mixes with low-temperature, low-humidity air at the indoor unit's fan blades, forming fine water droplets. These droplets are then flung by the fan blades to the indoor unit's sweeping blades, air guides, and even the indoor unit's air outlet, ultimately causing condensation and water blowing problems in the indoor unit. This invention proposes a dual-evaporation temperature air conditioner and an air intake control method for the air conditioner. By using a temperature sensor to detect the refrigerant temperature in each branch of the heat exchanger and adjusting the air intake angle of the air intake components according to the refrigerant temperature in each branch, the problem of refrigerant outlet temperature uniformity and outlet air temperature difference in each branch can be effectively improved.

[0124] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0125] Example

[0126] like Figures 1-9 As shown, the first aspect of this embodiment proposes an air conditioner comprising:

[0127] Housing 1, with an air inlet 11 on housing 1;

[0128] Indoor heat exchanger 2 is located inside the casing 1 and is opposite to the air inlet 11. Indoor heat exchanger 2 includes a front heat exchanger 2b and a rear heat exchanger 2a.

[0129] The front heat exchanger 2b includes a first front heat exchange unit A and a second front heat exchange unit B distributed along the length of the air inlet 11. The first front heat exchange unit A forms a first front heat exchange flow path A43, and the second front heat exchange unit B forms a second front heat exchange flow path B44. The first front heat exchange flow path A43 and the second front heat exchange flow path B44 are connected in parallel to form the front heat exchange flow path of the indoor heat exchanger 2.

[0130] The rear heat exchanger 2a includes a rear first heat exchange unit A and a rear second heat exchange unit B distributed along the length of the air inlet 11.

The rear first heat exchange flow path A53 and the rear second heat exchange flow path B54 are connected in parallel to form the rear heat exchange flow path of the indoor heat exchanger 2.

[0131] The front and rear heat exchange flow paths are connected in parallel to form the total heat exchange flow path of the indoor heat exchanger 2.

[0132] Air guide component 3 is located at air inlet 11. The air guide angle of air guide component 3 can be controlled and changed so that air inlet 11 can draw air into the first heat exchange unit 21 in the front row and / or into the second heat exchange unit 22 in the front row.

[0133] The controller is used to adjust the air guide angle of the air guide component 3 according to the outlet temperature of the first heat exchange flow path A43 in the front row and / or the outlet temperature of the second heat exchange flow path B44 in the front row and / or the outlet temperature of the first heat exchange flow path A53 in the rear row and / or the outlet temperature of the second heat exchange flow path B54 in the rear row and / or the operating mode of the air conditioner.

[0134] The operating modes of an air conditioner include cooling mode and heating mode.

[0135] The operating modes of an air conditioner include cooling mode and heating mode.

[0136] In this embodiment of the invention, the air conditioner obtains the outlet refrigerant temperature of each heat exchange path {front first heat exchange path A43, front second heat exchange path B44, rear first heat exchange path A53 and rear second heat exchange path B54} when operating in different modes. Based on the outlet refrigerant temperature, it can determine the heat exchange sufficiency of each heat exchange path. Therefore, it adjusts the air guide angle of the air guide component 3 according to the heat exchange effect, increases the heat exchange air volume of the heat exchange path with insufficient heat exchange, so as to make the heat exchange more sufficient and avoid the phenomenon of large outlet air temperature difference.

[0137] Specifically, such as Figure 4 and Figure 6 As shown, the first heat exchange unit A in the front row and the first heat exchange unit A in the rear row constitute the first heat exchange section 21 of the indoor heat exchanger 2, and the second heat exchange unit B in the front row and the second heat exchange unit B in the rear row constitute the second heat exchange section 22 of the indoor heat exchanger 2; as Figure 4 and Figure 6 As shown, the first heat exchange section 21 is located on the left side of the middle part of the air inlet 11, and the second heat exchange section 22 is located on the right side of the middle part of the air inlet 11.

[0138] like Figure 4 and Figure 6As shown, the indoor heat exchanger also includes a front heat exchanger main flow path A41, a front heat exchanger main flow path B42, a first distributor, and a second distributor. The collecting end of the first distributor is connected to the front heat exchanger main flow path A41, and the distributing end of the first distributor is connected to one end of the front first heat exchange flow path A43 and the front second heat exchange flow path B44. The collecting end of the second distributor is connected to the front heat exchanger main flow path B42, and the distributing end of the second distributor is connected to the other end of the front first heat exchange flow path A43 and the front second heat exchange flow path B44.

[0139] The indoor heat exchanger also includes a rear heat exchanger main flow path A51, a rear heat exchanger main flow path B52, a third distributor, and a fourth distributor. The collecting end of the third distributor is connected to the rear heat exchanger main flow path A51, and the distributing end of the third distributor is connected to one end of the rear first heat exchange flow path A53 and the rear second heat exchange flow path B54. The collecting end of the fourth distributor is connected to the rear heat exchanger main flow path B52, and the distributing end of the fourth distributor is connected to the other end of the rear first heat exchange flow path A53 and the rear second heat exchange flow path B54.

[0140] The controller is used to adjust the air guiding angle of the air guiding component 3 according to the temperature at the connection position of the first heat exchange flow path A43 and the main flow path A41 of the front heat exchanger and / or the connection position of the first heat exchange flow path A43 and the main flow path B42 of the front heat exchanger and / or the connection position of the second heat exchange flow path B44 and the main flow path A41 of the front heat exchanger and / or the connection position of the second heat exchange flow path B44 and the main flow path B42 of the front heat exchanger and / or the connection position of the first heat exchange flow path A53 and the main flow path A51 of the rear heat exchanger and / or the connection position of the first heat exchange flow path A53 and the main flow path B52 of the rear heat exchanger and / or the connection position of the second heat exchange flow path B54 and the main flow path A51 of the rear heat exchanger and / or the connection position of the second heat exchange flow path B54 and the main flow path B51 of the rear heat exchanger and / or the operating mode of the air conditioner.

[0141] Specifically, a first temperature sensing bulb A145 is provided at the connection position between the first heat exchange flow path A43 and the main flow path A41 of the front heat exchanger; a first temperature sensing bulb A246 is provided at the connection position between the first heat exchange flow path A43 and the main flow path B42 of the front heat exchanger; a first temperature sensing bulb B147 is provided at the connection position between the second heat exchange flow path B44 and the main flow path A41 of the front heat exchanger; and a first temperature sensing bulb B248 is provided at the connection position between the second heat exchange flow path B44 and the main flow path B42 of the front heat exchanger.

[0142] A second temperature sensor A155 is provided at the connection position between the first heat exchange flow path A53 and the main flow path A51 of the rear heat exchanger; a second temperature sensor A256 is provided at the connection position between the first heat exchange flow path A53 and the main flow path B52 of the rear heat exchanger; a second temperature sensor B157 is provided at the connection position between the second heat exchange flow path B54 and the main flow path A51 of the rear heat exchanger; and a second temperature sensor B258 is provided at the connection position between the second heat exchange flow path B54 and the main flow path B51 of the rear heat exchanger.

[0143] The controller is used to adjust the air guiding angle of the air guiding component 3 according to the temperature value of the first temperature sensing element A145 and / or the temperature value of the first temperature sensing element A246 and / or the temperature value of the first temperature sensing element B147 and / or the temperature value of the first temperature sensing element B248 and / or the temperature value of the second temperature sensing element A155 and / or the second temperature sensing element A256 and / or the temperature value of the second temperature sensing element B157 and / or the temperature value of the second temperature sensing element B258 and / or the operating mode of the air conditioner.

[0144] In this embodiment of the invention, the outlet temperature of each heat exchange path {front row first heat exchange path A43, front row second heat exchange path B44, rear row first heat exchange path A53 and rear row second heat exchange path B54} is obtained by setting a temperature sensing bulb.

[0145] Specifically, such as Figure 4 and Figure 5 As shown, when the air conditioner is running in cooling mode, the refrigerant in the main flow path A41 of the front heat exchanger flows to the first heat exchange path A43 and the second heat exchange path B44. Then, the refrigerant in the first heat exchange path A43 and the second heat exchange path B44 flows to the main flow path B42 of the front heat exchanger. The refrigerant in the main flow path A51 of the rear heat exchanger flows to the first heat exchange path A53 and the second heat exchange path B54 of the rear heat exchanger. The refrigerant in the first heat exchange path A53 and the second heat exchange path B54 of the rear heat exchanger flows to the main flow path B52 of the rear heat exchanger. At this time, the controller is used to adjust the air guiding angle of the air guiding component 3 according to the temperature difference between the first temperature sensing bulb B248 and the first temperature sensing bulb A246 and the temperature difference between the second temperature sensing bulb B258 and the second temperature sensing bulb A256.

[0146] Specifically, such as Figure 6 and Figure 7As shown, when the air conditioner is operating in heating mode, the refrigerant in the main flow path B42 of the front heat exchanger flows to the first heat exchange path A43 and the second heat exchange path B44. Then, the refrigerant in the first heat exchange path A43 and the second heat exchange path B44 flows to the main flow path A41 of the front heat exchanger. The refrigerant in the main flow path B52 of the rear heat exchanger flows to the first heat exchange path A53 and the second heat exchange path B54 of the rear heat exchanger. Then, the refrigerant in the first heat exchange path A53 and the second heat exchange path B54 of the rear heat exchanger flows to the main flow path A51 of the rear heat exchanger. At this time, the controller is used to adjust the air guiding angle of the air guiding component 3 according to the difference between the first temperature sensing bulb B147 and the first temperature sensing bulb A145, and the difference between the second temperature sensing bulb B157 and the second temperature sensing bulb A155.

[0147] Right now:

[0148] When the air conditioner is running as Figure 4 and Figure 5In the cooling mode shown, the refrigerant flows from the main flow path A41 of the front heat exchanger through the first heat exchange path A43 and the second heat exchange path B44 to the main flow path B42 of the front heat exchanger. Since the refrigerant temperature at the inlet position of the first heat exchange path A43 and the second heat exchange path B44 is the same, it is necessary to obtain the refrigerant temperature difference at the outlet position of the first heat exchange path A43 and the second heat exchange path B44. Because the flow paths of the refrigerant in the first heat exchange path A43 and the second heat exchange branch path 44 are different {most of the refrigerant in the first heat exchange path A43 flows through the first heat exchange section 21 located on the left side of the heat exchanger, and most of the refrigerant in the second heat exchange path B44 flows through the second heat exchange section 22 located on the right side of the heat exchanger}. Therefore, based on the temperature difference of the refrigerant at the outlet of the first heat exchange flow path A43 and the second heat exchange flow path B44, it can be determined whether the heat exchange of the two heat exchange branches at different locations is sufficient. If the refrigerant temperature at the outlet of the first heat exchange flow path A43 is higher than that at the outlet of the second heat exchange flow path B44, it indicates that the refrigerant in the second heat exchange flow path B44 has not undergone sufficient heat exchange with the air, and the refrigerant temperature is low. At this time, the air guide component 3 can be adjusted to blow air from the air inlet 11 to the second heat exchange section 22 of the indoor heat exchanger 2 where the second heat exchange flow path B44 is located, so that more air volume is concentrated in the second heat exchange section 22 of the indoor heat exchanger 2, so that the refrigerant in the second heat exchange flow path B44 can undergo sufficient heat exchange and increase the refrigerant temperature at the outlet of the second heat exchange flow path B44. Similarly, if the refrigerant temperature at the outlet of the first heat exchange flow path A43 is lower than the refrigerant temperature at the outlet of the second heat exchange flow path B44, it indicates that the refrigerant in the first heat exchange flow path A43 has not undergone sufficient heat exchange. In this case, the air guide component 3 can be adjusted to make the air inlet 11 blow air into the first heat exchange section 22 of the indoor heat exchanger 2 where the first heat exchange flow path A43 is located, so that the refrigerant in the first heat exchange flow path A43 can undergo sufficient heat exchange and increase the refrigerant temperature at the outlet of the first heat exchange flow path A43.

[0149] When the air conditioner is running as Figure 6 and Figure 7In the heating mode shown, the refrigerant flows from the main flow path B42 of the front heat exchanger through the first heat exchange path A43 and the second heat exchange path B44 to the main flow path A41 of the front heat exchanger. Since the refrigerant temperature at the inlet position of the first heat exchange path A43 and the second heat exchange path B44 is the same, it is necessary to obtain the refrigerant temperature difference at the outlet position of the first heat exchange path A43 and the second heat exchange path B44. This is because the refrigerant in the first heat exchange path A43 and the second heat exchange branch path B44... The flow paths are different: {most of the refrigerant in the first heat exchange path A43 flows through the first heat exchange section 21 on the left side of the indoor heat exchanger 2, while most of the refrigerant in the second heat exchange path B44 flows through the second heat exchange section 22 on the right side of the indoor heat exchanger 2}. Therefore, based on the difference in refrigerant temperature at the outlet positions of the first heat exchange path A43 and the second heat exchange path B44, the heat exchange effect of the two heat exchange branches at different locations can be determined. If the outlet position of the first heat exchange path A43 is controlled... If the refrigerant temperature is higher than the refrigerant temperature at the outlet of the second heat exchange flow path B44, then the refrigerant in the second heat exchange flow path B44 has not undergone sufficient heat exchange with the air, resulting in a lower refrigerant temperature. In this case, the air guide component 3 can be adjusted to direct airflow from the air inlet 11 to the second heat exchange section 22 of the indoor heat exchanger 2 where the second heat exchange flow path B44 is located. This concentrates a larger volume of air in the second heat exchange section 22 of the indoor heat exchanger 2, improving the heat exchange effect of the refrigerant in the second heat exchange flow path B44 and increasing the temperature at the outlet of the second heat exchange flow path B44. Similarly, if the refrigerant temperature at the outlet of the first heat exchange flow path A43 is lower than the refrigerant temperature at the outlet of the second heat exchange flow path B44, it indicates that the refrigerant in the first heat exchange flow path A43 has not undergone sufficient heat exchange. In this case, the air guide component 3 can be adjusted to make the air inlet 11 blow air onto the first heat exchange section 22 of the indoor heat exchanger 2 where the first heat exchange flow path A43 is located, thereby improving the heat exchange effect of the refrigerant in the first heat exchange flow path A43 and increasing the refrigerant temperature at the outlet of the first heat exchange flow path A43.

[0150] Similarly, the same principle is used to determine whether the first heat exchange path A53 and the second heat exchange path B54 in the rear row are sufficiently heat exchanged.

[0151] It is worth noting that since the indoor heat exchanger 2 includes a front heat exchanger 2b and a rear heat exchanger 2a arranged along the direction of the air inlet 11, it is necessary not only to determine whether the heat exchange of the first heat exchange flow path A43 and the second heat exchange flow path B44 in the front row is sufficient, but also to determine whether the heat exchange of the first heat exchange flow path A53 and the second heat exchange flow path B54 in the rear row is sufficient. Then, based on the heat exchange conditions of the first heat exchange flow path A43 and the second heat exchange flow path B44 in the front row and the first heat exchange flow path A53 and the second heat exchange flow path B54 in the rear row, it is necessary to comprehensively judge whether the heat exchanger will have problems such as condensation or water blowing during heat exchange.

[0152] like Figures 5-7 As shown, the heat exchange system includes:

[0153] Compressor 6 includes a high-temperature suction port 61, a low-temperature suction port 62, a make-up air port 63, and a discharge port 64;

[0154] The first four-way valve component 7 includes a first four-way valve component A port 7a, a first four-way valve component B port 7b, a first four-way valve component C port 7c, and a first four-way valve component D port 7d. The first four-way valve component 7 is designed such that: when the first four-way valve component A port 7a and the first four-way valve component B port 7b are connected, the first four-way valve component C port 7c and the first four-way valve component D port 7d are connected; or when the first four-way valve component A port 7a and the first four-way valve component D port 7d are connected, the first four-way valve component B port 7b and the first four-way valve component C port 7c are connected.

[0155] The second four-way valve component 8 includes a second four-way valve component A port 8a, a second four-way valve component B port 8b, a second four-way valve component C port 8c, and a second four-way valve component D port 8d. The second four-way valve component 8 is designed such that: when the second four-way valve component A port 8a and the second four-way valve component B port 8b are connected, the second four-way valve component C port 8c and the second four-way valve component D port 8d are connected; or when the second four-way valve component A port 8a and the second four-way valve component D port 8d are connected, the second four-way valve component B port 8b and the second four-way valve component C port 8c are connected.

[0156] Outdoor heat exchanger 9 and flash evaporator 10, outdoor heat exchanger 9 includes outdoor heat exchanger A port 9a and outdoor heat exchanger B port 9b, flash evaporator 10 includes flash evaporator A port 10a, flash evaporator B port 10b and flash evaporator C port 10c.

[0157] The compressor discharge port 64 is connected to both port B 7b of the first four-way valve component and port B 8b of the second four-way valve component. Both port A 7a of the first four-way valve component and port A 8a of the second four-way valve component are connected to port A 9a of the outdoor heat exchanger. Port B 9b of the outdoor heat exchanger is connected to port A 10a of the flash evaporator. Port B 10b of the flash evaporator is connected to the compressor injection port 63. Port C 10c of the flash evaporator is connected to the main flow path A41 of the front heat exchanger and the main flow path A51 of the rear heat exchanger. The main flow path B42 of the front heat exchanger is connected to port C 7c of the first four-way valve component. The main flow path B52 of the rear heat exchanger is connected to port C 8c of the second four-way valve component. Port D 7d of the first four-way valve component is connected to the low-temperature suction port of the compressor. Port D 8d of the second four-way valve component is connected to the high-temperature suction port 61 of the compressor.

[0158] A first throttling device 100 is provided between the outdoor heat exchanger B port 9b and the flash evaporator A port 10a. A second throttling device 200 is provided between the flash evaporator C port 10c and the main flow path A41 of the front heat exchanger and the main flow path A51 of the rear heat exchanger. A third throttling device 300 is also provided on the main flow path A41 of the front heat exchanger.

[0159] Specifically, when the air conditioner is running in cooling mode, the first four-way valve component A port 7a and the first four-way valve component B port 7b are connected, the first four-way valve component C port 7c and the first four-way valve component D port 7d are connected, the second four-way valve component A port 8a and the second four-way valve component B port 8b are connected, and the second four-way valve component C port 8c and the second four-way valve component D port 8d are connected.

[0160] When the air conditioner is in heating mode, when port A 7a of the first four-way valve component is connected to port D 7d of the first four-way valve component, port B 7b of the first four-way valve component is connected to port C 7c of the first four-way valve component, and when port A 8a of the second four-way valve component is connected to port D 8d of the second four-way valve component, port B 8b of the second four-way valve component is connected to port C 8c of the second four-way valve component.

[0161] like Figure 5 As shown, when the air conditioner is in cooling mode, low-pressure, low-temperature refrigerant is drawn in from the high-temperature suction port 61, low-temperature suction port 62, and make-up port 63 of the compressor 6. It is then compressed by the compressor 6 into a high-temperature, high-pressure vapor refrigerant, which is discharged from the exhaust port 64. Simultaneously, it flows through the first four-way valve component 7 and the second four-way valve component 8 to the outdoor heat exchanger 9. Through the outdoor heat exchanger 9, it undergoes condensation and heat exchange, cooling into a high-pressure, medium-temperature refrigerant. After passing through the first throttling device 100, the refrigerant becomes a low-temperature, low-pressure vapor-liquid two-phase state. The two-phase refrigerant enters the flash evaporator 10 and splits into two paths. One path, the gaseous refrigerant, flows out through flash evaporator port B 10b and returns to the compressor's make-up port 64. The other path, the refrigerant, flows out through flash evaporator port C. 10c flows to the second throttling device 200 for secondary throttling, resulting in lower refrigerant temperature and pressure. At this time, the refrigerant is again split into two paths and enters the indoor heat exchanger 2 component. One path of refrigerant flows through the main flow path A51 of the rear heat exchanger and then through the front heat exchanger 2b for evaporation and heat exchange, absorbing heat from the air for the first time and evaporating into gaseous refrigerant. It then returns to the high-temperature suction port 61 of the compressor 6 through the second four-way valve component 8. The other path of refrigerant flows through the third throttling device 300 of the main flow path A41 of the front heat exchanger for the third time and then through the rear heat exchanger 2a for the second time to absorb heat from the air. After absorbing heat, the refrigerant becomes gaseous refrigerant and returns to the low-temperature suction port 62 of the compressor 6 through the first four-way valve component 7.

[0162] like Figure 7As shown, when the air conditioner is in heating mode, low-pressure, low-temperature refrigerant is drawn in from the high-temperature suction port 61, low-temperature suction port 62, and replenishment port 63 of the compressor 6. After being compressed by the compressor 6 into high-temperature, high-pressure vapor refrigerant, it is discharged from the exhaust port 64. At the four-way valve components {first four-way valve component 7 and second four-way valve component 8}, it splits into two paths, which lead to the rear heat exchanger 2a and the front heat exchanger 2b of the room respectively for heat exchange. One path flows through the first four-way valve component 7 to the rear heat exchanger 2a of the room for condensation heat exchange, cooling it into high-pressure, medium-temperature refrigerant. The other path flows through the second four-way valve component 8 to the front heat exchanger 2b of the room for condensation heat exchange, cooling it into high-pressure, medium-temperature refrigerant. The two refrigerant paths converge before the second throttling device 200. The third throttling device 300 is opened to its maximum in heating mode and does not have a throttling effect. After the refrigerant undergoes its first throttling process via the third throttling device 300, it becomes a low-temperature, low-pressure vapor-liquid two-phase state and enters the flash evaporator 10. At the flash evaporator 10, it splits into two paths. One path, the gaseous refrigerant, flows out through the flash evaporator's B port 10b and returns to the compressor 6's gas supply port 64. The other path enters the first throttling device 100 for a second throttling process, resulting in even lower refrigerant temperature and pressure. Then, the refrigerant undergoes evaporation and heat exchange in the outdoor heat exchanger 9 at 32. Afterward, the refrigerant is again split into two paths and returns to the compressor's suction port. One path returns to the compressor's low-temperature suction port 62 via the first four-way valve component 7, and the other path returns to the compressor's high-temperature suction port 61 via the second four-way valve component 8.

[0163] In any of the above embodiments, such as Figure 4 and Figure 6 As shown, the front heat exchanger 2b is located on the windward side of the air inlet 11, and the rear heat exchanger 2a is located on the leeward side of the air inlet 11.

[0164] It is worth noting that during cooling, the refrigerant temperature and pressure flowing out of the front heat exchanger 2b are higher than those flowing out of the rear heat exchanger 2a {because during cooling, the refrigerant in the front heat exchanger 2b does not pass through the third throttling device 300, resulting in higher pressure and temperature}. Therefore, placing the front heat exchanger 2b close to the air inlet 11 allows for the gradual cooling of the incoming airflow using both the front and rear heat exchangers 2b and 2a. However, if the rear heat exchanger 2a is placed close to the air inlet 11, the front heat exchanger 2b loses its cooling effect on the airflow {because the rear heat exchanger 2a has lower pressure and temperature than the front heat exchanger 2b, directly cooling the air to a lower temperature}. Furthermore, since the refrigerant pressure and temperature in the front heat exchanger 2b are relatively higher, introducing the refrigerant from the front heat exchanger 2b into the high-temperature suction port 61 of the compressor 6 can also reduce the energy consumption of the compressor 6.

[0165] In any of the above embodiments, such as Figures 1-3As shown, the housing 1 has a first housing wall 1a and a second housing wall 1b located on both sides of the air inlet 11 along its length.

[0166] A first heat exchange area 400 is defined between the first heat exchange section 21 of the indoor heat exchanger 2, the air inlet 11 and the first casing wall 1a of the casing.

[0167] The second heat exchange zone 500 is defined between the second heat exchange section 22 of the indoor heat exchanger 2, the air inlet 11, and the second housing wall 1b of the housing.

[0168] In any of the above embodiments, such as Figures 1-3 As shown, the first heat exchange section 21 and the second heat exchange section 22 of the indoor heat exchanger 2 define a fan installation area 600 between the fan and the casing 1 on the side away from the air inlet 11. The fan installation area is provided with a fan 700, and the air conditioner has an air outlet 800 that communicates with the air outlet side of the fan.

[0169] In any of the above embodiments, such as Figures 1-3 As shown, the air guide component 3 includes multiple air guide blades disposed at the air inlet 11;

[0170] Multiple air guide blades are linked together and are evenly distributed along the length of the air inlet 11.

[0171] In any of the above embodiments, such as Figures 1-3 As shown, the above-mentioned dual-evaporation temperature air conditioner is a wall-mounted air conditioner.

[0172] Furthermore, such as Figure 8 and Figure 9 As shown, a second aspect of the present invention also provides an air intake control method for a dual-evaporation temperature air conditioner, which is applied to the above-mentioned dual-evaporation temperature air conditioner, wherein the air intake control method includes:

[0173] The air guide angle of the air guide component 3 is adjusted according to the outlet temperature of the first heat exchange flow path A43 in the front row and / or the outlet temperature of the second heat exchange flow path B44 in the front row and / or the outlet temperature of the first heat exchange flow path A53 in the rear row and / or the outlet temperature of the second heat exchange flow path B54 in the rear row and / or the operating mode of the air conditioner.

[0174] In this embodiment of the invention, the air conditioner obtains the outlet refrigerant temperature of each heat exchange path {front first heat exchange path A43, front second heat exchange path B44, rear first heat exchange path A53 and rear second heat exchange path B54} when operating in different modes. Based on the outlet refrigerant temperature, it can determine the heat exchange sufficiency of each heat exchange path. Therefore, it adjusts the air guide angle of the air guide component 3 according to the heat exchange effect, increases the heat exchange air volume of the heat exchange path with insufficient heat exchange, so as to make the heat exchange more sufficient and avoid the phenomenon of large outlet air temperature difference.

[0175] Specifically, the air guiding angle of the air guiding component 3 is adjusted according to the outlet temperature of the first heat exchange flow path A43 in the front row and / or the outlet temperature of the second heat exchange flow path B44 in the front row and / or the outlet temperature of the first heat exchange flow path A53 in the rear row and / or the outlet temperature of the second heat exchange flow path B54 in the rear row and / or the operating mode of the air conditioner, including:

[0176] Acquire the temperature value of the first temperature sensor A145 and / or the temperature value of the first temperature sensor A246 and / or the temperature value of the first temperature sensor B147 and / or the temperature value of the first temperature sensor B248 and / or the temperature value of the second temperature sensor A155 and / or the temperature value of the second temperature sensor A256 and / or the temperature value of the second temperature sensor B157 and / or the temperature value of the second temperature sensor B258 and / or the operating mode of the air conditioner;

[0177] The air guide angle of the air guide component 3 is adjusted according to the temperature values ​​of the first temperature sensor A145 and / or the first temperature sensor A246 and / or the first temperature sensor B147 and / or the first temperature sensor B248 and / or the second temperature sensor A155 and / or the second temperature sensor A256 and / or the second temperature sensor B157 and / or the second temperature sensor B258 and / or the operating mode of the air conditioner.

[0178] The air conditioner in this embodiment of the invention obtains the temperature values ​​of the first temperature sensor A145 and / or the first temperature sensor A246 and / or the first temperature sensor B147 and / or the first temperature sensor B248 and / or the second temperature sensor A155 and / or the second temperature sensor A256 and / or the second temperature sensor B157 and / or the second temperature sensor B258 when operating in different modes. This allows the air conditioner to obtain the outlet refrigerant temperature of each heat exchange branch path {front first heat exchange path A, front second heat exchange path B, rear first heat exchange path A, and rear second heat exchange path B}. Based on the outlet refrigerant temperature, the air conditioner can determine the heat exchange sufficiency of the two branch paths branching from each main path. Then, based on the heat exchange effect, the air guide angle of the air guide component is adjusted to increase the heat exchange airflow in the branch paths with poor heat exchange effect, thereby improving the heat exchange effect and avoiding a large temperature difference in the outlet air.

[0179] Furthermore, the air guiding angle of the air guiding component 3 is adjusted according to the temperature values ​​of the first temperature sensing bulb A145 and / or the first temperature sensing bulb A246 and / or the first temperature sensing bulb B147 and / or the first temperature sensing bulb B248 and / or the second temperature sensing bulb A155 and / or the second temperature sensing bulb A256 and / or the second temperature sensing bulb B157 and / or the second temperature sensing bulb B258 and / or the operating mode of the air conditioner, including:

[0180] When the air conditioner is running in cooling mode, the temperature difference Δt1 between the first temperature sensor B248 and the first temperature sensor A246 and the temperature difference Δt2 between the second temperature sensor B258 and the second temperature sensor A256 are obtained, and the air guiding angle of the air guiding component is adjusted according to Δt1 and Δt2.

[0181] When the air conditioner is in heating mode, the difference Δt3 between the first temperature sensor B147 and the first temperature sensor A145, and the difference Δt4 between the second temperature sensor B157 and the second temperature sensor A155 are obtained, and the air guiding angle of the air guiding component is adjusted according to Δt3 and Δt4.

[0182] Specifically, when the air conditioner is operating in cooling mode, the air guide angle of the air guide component is adjusted according to Δt1 and Δt2, including:

[0183] Calculate the absolute value of the sum of △t1 and △t2. If the absolute value of the sum of △t1 and △t2 is greater than the first preset value, adjust the air guiding angle of the air guiding component. If the absolute value of the sum of △t1 and △t2 is less than or equal to the first preset value, maintain the current air guiding angle of the air guiding component.

[0184] In the air conditioner's heating mode, the air guide angle of the air guide component is adjusted according to Δt3 and Δt4, including:

[0185] Calculate the absolute value of the sum of △t3 and △t4. If the absolute value of the sum of △t3 and △t4 is greater than the first preset value, adjust the air guiding angle of the air guiding component. If the absolute value of the sum of △t3 and △t4 is less than or equal to the first preset value, maintain the current air guiding angle of the air guiding component.

[0186] It should be noted that in cooling mode, when the absolute value of the sum of Δt1 and Δt2 is greater than the first preset value, it indicates that the refrigerant in the first heat exchange section 21 or the second heat exchange section 22 of the indoor heat exchanger 2 is not sufficiently heat-exchanged. At this time, the air conditioner will experience hot and cold air convection, which is prone to condensation. Therefore, it is necessary to increase the air volume at the location where the heat exchange is insufficient so that the refrigerant that has not been sufficiently heat-exchanged can be fully heat-exchanged.

[0187] Similarly, in heating mode, when the absolute value of the sum of Δt3 and Δt4 is greater than the first preset value, it also indicates that the refrigerant in the first heat exchange section 21 or the refrigerant in the second heat exchange section 22 of the indoor heat exchanger 2 is not sufficiently heat-exchanged. At this time, the air conditioner will experience hot and cold air convection, which is prone to condensation. Therefore, it is necessary to increase the air volume at the location where the heat exchange is insufficient so that the refrigerant that has not been sufficiently heat-exchanged can be fully heat-exchanged.

[0188] Specifically, in cooling mode, when the absolute value of the sum of Δt1 and Δt2 is greater than a first preset value, the air guiding angle of the air guiding component is adjusted, including:

[0189] If both Δt1 and Δt2 are negative, the air intake component is controlled to rotate counterclockwise by a first preset angle so that the air inlet is directed toward the second heat exchange section. In cooling mode, when both Δt1 and Δt2 are negative, it indicates that the refrigerant temperature at the first heat exchange section 21 of the indoor heat exchanger 2 is high and the refrigerant temperature at the second heat exchange section 22 of the indoor heat exchanger 2 is low. This indicates that the refrigerant at the second heat exchange section 22 has not exchanged heat sufficiently with the air. Therefore, the airflow needs to be directed to the second heat exchange section 22 to exchange heat sufficiently with the refrigerant at the second heat exchange section 22.

[0190] If both Δt1 and Δt2 are positive, the air intake component is controlled to rotate clockwise by a first preset angle so that the air inlet is directed toward the first heat exchange section. In cooling mode, when both Δt1 and Δt2 are positive, it indicates that the refrigerant temperature at the first heat exchange section 21 of the indoor heat exchanger 2 is low and the refrigerant temperature at the second heat exchange section 22 of the indoor heat exchanger 2 is low. This indicates that the refrigerant at the first heat exchange section 21 has not exchanged heat with the air sufficiently. Therefore, the airflow needs to be directed to the first heat exchange section 21 to exchange heat with the refrigerant at the second heat exchange section 21 sufficiently.

[0191] In heating mode, when the absolute value of the sum of Δt3 and Δt4 is greater than a first preset value, the air guide angle of the air guide component is adjusted, including:

[0192] If both Δt3 and Δt4 are negative, the air intake component is controlled to rotate clockwise by a first preset angle so that the air inlet is directed toward the first heat exchange section 21. In heating mode, when both Δt3 and Δt4 are negative, it indicates that the refrigerant temperature at the first heat exchange section 21 of the indoor heat exchanger 2 is high and the refrigerant temperature at the second heat exchange section 22 of the indoor heat exchanger 2 is low. This indicates that the refrigerant at the first heat exchange section 21 has not exchanged heat with the air sufficiently. Therefore, the airflow needs to be directed to the first heat exchange section 21 to exchange heat with the refrigerant at the first heat exchange section 21 sufficiently.

[0193] If both Δt3 and Δt4 are positive, the air intake component is controlled to rotate counterclockwise by a first preset angle so that the air inlet is directed toward the second heat exchange section. In heating mode, when both Δt1 and Δt2 are positive, it indicates that the refrigerant temperature at the first heat exchange section 21 of the indoor heat exchanger 2 is low and the refrigerant temperature at the second heat exchange section 22 of the indoor heat exchanger 2 is low. This indicates that the refrigerant at the second heat exchange section 22 has not exchanged heat sufficiently with the air. Therefore, the airflow needs to be directed to the second heat exchange section 22 to exchange heat sufficiently with the refrigerant at the second heat exchange section 22.

[0214] When conditions one and six are met, or conditions two and five are met, or conditions three and four are met, the air intake angle of the air intake component remains unchanged.

[0215] When conditions two and six are met, or conditions three and five are met, or conditions three and six are met, the air inlet component is controlled to rotate clockwise by a second preset angle so that the air inlet is directed toward the first heat exchange section.

[0221] Example 2

[0222] This embodiment also provides a single-evaporation temperature air conditioner, the air conditioner comprising:

[0223] Housing 1, with an air inlet 11 on housing 1;

[0224] Indoor heat exchanger 2 is located inside the casing 1 and is opposite to the air inlet 11. Indoor heat exchanger 2 has a first heat exchange section 21 and a second heat exchange section 22.

[0225] The air inlet 11 is provided with an air guide component 3. The air guide angle of the air guide component 3 can be controlled and changed so that the air inlet 11 can draw air into the first heat exchange section 21 and / or into the second heat exchange section 22.

[0226] The heat exchanger includes a main heat exchange path A and a main heat exchange path B, as well as a branch heat exchange path A and a branch heat exchange path B for connecting the main heat exchange path A and the main heat exchange path B. Branch heat exchange path A flows through the first heat exchange section 21, and branch heat exchange path B flows through the second heat exchange section 22.

[0227] A temperature sensor A1 is installed at the connection point between heat exchange branch A and heat exchange main A, and a temperature sensor A2 is installed at the connection point between heat exchange branch A and heat exchange main B.

[0228] A temperature sensing bulb B1 is installed at the connection point between the heat exchange branch path B and the main heat exchange path A, and a temperature sensing bulb B2 is installed at the connection point between the heat exchange branch path B and the main heat exchange path B.

[0229] The controller is used to adjust the air guide angle of the air guide component 3 according to the temperature value of temperature sensor A1 and / or temperature sensor A2 and / or temperature sensor B1 and / or temperature sensor B2 and / or the operating mode of the air conditioner.

[0230] In this embodiment, the single-evaporation temperature air conditioner adjusts the angle of the air inlet 11 using the baffle component 3. The adjustment principle is similar to that in embodiment 1. Both methods determine the heat exchange sufficiency of different heat exchange parts of the heat exchanger based on the refrigerant temperature value at the outlet of the heat exchange flow path. When it is determined that a certain heat exchange part has not undergone sufficient heat exchange, the airflow from the air inlet 11 is directed to this location to ensure that the refrigerant at this location undergoes sufficient heat exchange with the air, thus avoiding problems such as condensation and water blowing caused by large temperature differences between different heat exchange locations.
