Description

Technical Field

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

[0002] The air conditioner includes a compressor, a condenser, and an evaporator; the compressor compresses low-pressure gaseous refrigerant into high-pressure gaseous refrigerant; the condenser cools the high-pressure gaseous refrigerant into low-pressure liquid refrigerant; the evaporator evaporates the low-pressure liquid refrigerant, absorbs heat, and cools the medium passing through it. The cold air flow is blown into the room through the fan to cool the indoor environment, and the temperature of the cold air flow blown into the room can be adjusted by adjusting the set temperature. That is, the lower the set temperature, the lower the temperature of the air flow blown into the room, and the fresher the room. Increasing the set temperature will increase the temperature of the air flow blown into the room, the room temperature will rise, and the user's comfort will deteriorate.

[0003] Nowadays, air conditioners have become an indispensable tool for summer heat relief, and people often set the air conditioner temperature lower in pursuit of coolness, resulting in a lower air outlet temperature. When the low-temperature cold air flow of the air conditioner blows on the body, it will cause the joints, neck and other parts to get cold, causing discomfort, commonly known as air-conditioning disease. As people's pursuit of healthy life becomes higher and higher, the discomfort caused by the cold air flow of the air conditioner blowing directly on the human body has also attracted more and more attention. Therefore, the problem of improving the cold air flow without reducing the cooling capacity of the air conditioner needs to be solved urgently.

[0004] The existing four-air outlet air conditioner includes four air outlets located on the periphery and an air inlet grille located in the middle of the four air outlets; an air duct is arranged between the air inlet grille and the air outlet; an evaporator and a fan are arranged in the air duct, so that indoor air enters the air duct from the air inlet grille and flows out from the air outlet after heat exchange by the evaporator, thereby cooling the indoor environment.

[0005] Each air outlet is provided with an air guide plate, which can be swung and set at different angles. When the air guide plate is swung or set at different angles, the angle at which the cold air flows out is changed, thereby adjusting the area where the cold air flows to fall, and preventing the cold air from blowing onto the body.

[0006] However, offices, conference rooms and other places are often densely populated, and the angle adjustment of the air deflector cannot take care of everyone, so the angle adjustment of the air deflector has certain limitations.

[0066] The air conditioner performs the air conditioner's refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0067] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0068] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0069] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0070] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0071] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The air conditioner in the present application includes an indoor unit; the indoor unit includes a shell (not shown in the drawings), a panel assembly 1, a heat exchange assembly 2, and a fan 3, which drives the indoor air to enter the shell through the fan 3, and then heat exchange with the heat exchange assembly 2 in the shell to increase or decrease the temperature and then be discharged from the shell to the outside of the shell, thereby realizing the circulation regulation of the indoor environment temperature.

[0072] The shell is a cylindrical box body with one end open and the other end closed, including a first opening. The panel assembly 1 is fixedly mounted on the first opening to form a closed cavity in the shell for mounting the fan 3 and the heat exchange assembly 2.

[0073] The heat exchange assembly 2 includes a cylindrical heat exchanger 21, which is fixedly disposed in a closed cavity formed by the shell and the panel assembly 1, with two ends corresponding to two ends of the shell. The fan 3 is fixedly disposed inside the cylinder of the heat exchanger 21.

[0074] An air inlet 11 is formed in the middle of the panel assembly 1; a plurality of air outlets 12 are formed on the panel assembly 1 at positions around the air inlet; at least one of the air outlets 12 is correspondingly provided with an air supply port 13 and an air supply duct 17; one end of the air supply duct 17 is connected to the air supply port 13, and the other end is connected to the corresponding air outlet 12. The air inlet 11, each air outlet 12, and each air supply port 13 are respectively connected to the indoor environment.

[0075] The edges around one end of the heat exchanger 21 are connected to the panel assembly 1 and are located between the air inlet 11 and each air outlet 12; the fan 3 is located in the cylinder of the heat exchanger 21, corresponding to the air inlet 11. When the fan 3 is started, the airflow of the indoor air enters the cylinder of the heat exchanger 21 in the shell from the air inlet 11, and passes through the heat exchanger 21 to flow around the shell through the centrifugal action of the fan 3; the airflow of the indoor air passing through the heat exchanger 21 exchanges heat with the heat exchanger 21 to increase or decrease the temperature; the airflow of the indoor air after the temperature increase or decrease flows out from the air outlet 12 to adjust the temperature of the indoor environment.

[0076] One end of the air supply duct 17 is connected to the indoor environment through the air supply port 13, and the other end is connected to the air outlet 12. When the fan 3 is started, the airflow of the heated or cooled indoor air flows out from the air outlet 12, driving part of the indoor air to enter the air supply duct 17 from the air supply port 13, and driving the indoor air in the air supply duct 17 connected to the air outlet 12 to flow out together, and before flowing out, part of the indoor air flowing out of the air supply duct 17 is mixed with the heated or cooled indoor air and then flows out from the air outlet 12.

[0077] Of course, the fan 3 can also be a cross-flow fan, which is arranged on the inner side of the air outlet 12 and outside the cylinder of the heat exchanger 21. The indoor air enters the cylinder of the heat exchanger 21 from the air inlet 11 through the drive of the fan 3, and then is blown out of the air outlet 12 by the fan 3 after heat exchange in the heat exchanger 21.

[0078] The air conditioner of the present invention is provided with an independent air supply channel with two ends connected to the indoor environment and the air outlet 12 respectively, so as to guide the indoor air to enter the air outlet 12 and mix with the indoor air after heat exchange to flow out; the indoor air introduced by the air supply duct 17 does not participate in the heat exchange and does not change the effective air volume participating in the heat exchange, thereby achieving the goal of increasing the air outlet temperature of the air outlet 12 without reducing the cooling efficiency and without affecting the unit capacity and energy efficiency.

[0079] In addition, the airflow of indoor air introduced by the air supply duct 17 does not pass through the fan, but is guided by the aerodynamic principle of low pressure near the outlet of the air supply duct 17 caused by the drainage through the air outlet 12. Not only does it not add additional driving fans, it reduces control components, improves control efficiency and saves more energy, and avoids the noise problem caused by the fan shaking when the indoor air flow introduced by the air supply duct 17 enters the fan 3 from the side; it also reduces the noise generated by adding additional driving fan equipment, reduces noise, and improves user experience.

[0080] Furthermore, since the air volume involved in heat exchange remains unchanged, it is blown into the room from the air outlet 12 together with the indoor air flow introduced by the air supply duct 17, increasing the air volume, making the user feel more obvious, and improving the user experience. In addition, the mixed air volume entering from the air supply duct 17 is determined by the wind speed of the air outlet 12; when the air volume level is high, the wind speed of the air outlet 12 is relatively high, and the indoor air volume brought in by the air supply duct 17 for mixed air increases accordingly through the aerodynamic principle; when the air volume level is low, the wind speed of the air outlet 12 is relatively low, and the indoor air volume brought in by the air supply duct 17 for mixed air decreases accordingly through the aerodynamic principle; that is, when the air volume level is high or low, the air supply structure of the air conditioner of the present invention can enhance the user's air volume demand, and the mixed air temperature does not change significantly, thereby improving the user experience.

[0081] The specific structure and principle of the air conditioner of the present invention are described in detail below through specific embodiments.

[0086] The indoor unit of the air conditioner in this embodiment is a ceiling-mounted type with four air outlets 12. The four air outlets make the air outlet range wide and are suitable for places with larger spaces, such as large conference rooms, reception rooms, etc. The air conditioner of the present invention respectively sets air supply ports 13 and air supply ducts 17 at the four air outlets 12 to supplement the temperature-regulated air flow at the air outlet with the indoor normal temperature air flow, thereby adjusting the air outlet temperature, improving the air outlet comfort, and enhancing the user experience.

[0087] In a specific embodiment, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 The air inlet 11 is set as a grille-type central air inlet 11 structure; that is, the air inlet 11 is set in the middle of the panel assembly 1, corresponding to the cross-section of the cylinder of the heat exchanger 21, to maximize the area of ​​the air inlet 11, reduce the air intake resistance, and increase the air intake volume.

[0089] Each air supply port 13 is a long through-hole structure located between the air inlet 11 and each air outlet 12 and arranged along the length direction of each air outlet 12 .

[0090] The length direction of the air supply port 13 of the air conditioner of this embodiment is the same as and corresponds to the length direction of the air outlet 12, so that the air supply port 13 adapts to the length of the air outlet 12 and improves the air supply efficiency.

[0093] The air conditioner of this embodiment is provided with an air outlet duct 19 so that when the air conditioner is running and discharging air, a low-pressure area relative to the middle of the air outlet duct 19 is formed near the inner wall of the air outlet duct 19 due to the principle of aerodynamics, thereby increasing the area of ​​the low-pressure area; the make-up air duct 17 is connected and communicated with the air outlet duct 19 to ensure the make-up air volume, thereby ensuring the make-up air effect, increasing the air outlet temperature during cooling, and improving the user experience.

[0094] In a specific embodiment, referring to Figure 3 , Figure 4 The air supply duct 17 includes an air inlet cavity 171 and an air outlet cavity.

[0095] The air inlet cavity 171 is a cavity along the length direction of the air outlet 12 and is connected to the corresponding air supply ports 13 respectively, so as to increase the air volume of the indoor air entering the air supply duct 17 through the air supply ports 13.

[0096] The air outlet cavity includes a plurality of air induction ducts 172 spaced apart and evenly arranged along the length direction of the air outlet 12 , which are hole-shaped passages, one end of which is connected and communicated with the air inlet cavity 171 , and the other end of which is connected and communicated with the air outlet duct 19 .

[0097] The air conditioner of this embodiment is provided with an air inlet chamber 171 connected to the cavity to increase the air volume of indoor air entering the air supply duct 17 for air supply and mixing; the air outlet chamber including a plurality of air induced ducts 172 is respectively connected to the air inlet chamber 171 and the air outlet duct 19, and the indoor air in the air inlet chamber 171 is introduced into the air outlet duct 19 through each air induced duct 172, so that the indoor air forms multiple airflows through each air induced duct 172 and converges into the air outlet duct 19, which fully disturbs the airflow of the heated or cooled indoor air in the air outlet duct 19, makes the airflow blown out of the air outlet 12 more easily diverge, reduces the direct blowing effect, improves comfort, and thus improves user experience.

[0098] In a specific embodiment, referring to Figure 3 , Figure 4 Each air induction duct 172 of each air outlet cavity is a gradually shrinking channel along the direction from the air inlet cavity 171 to the air outlet duct 19.

[0099] The air conditioner of this embodiment forms a nozzle-type structure through the air duct 172 of the tapered hole-shaped channel, which increases the ejection speed of the indoor air used for air supply without the drive of additional auxiliary equipment, so that the airflow of the indoor air in the air supply duct 17 and the airflow of the indoor air in the air outlet duct 19 are mixed more fully.

[0100] In a specific embodiment, referring to Figure 3 , Figure 4 Each air duct 172 of the air outlet cavity includes a first aperture section 173 and a second aperture section 174 .

[0101] The cross-sectional dimension of the transverse section of the first aperture section 173 is greater than the cross-sectional dimension of the transverse section of the second aperture section 174; that is, the cross-sectional dimension of the channel of the first aperture section 173 is greater than the cross-sectional dimension of the channel of the second aperture section 174. One end of the first aperture section 173 is connected and communicated with the air inlet cavity 171, and the other end is connected and communicated with one end of the second aperture section 174; the other end of the second aperture section 174 is connected and communicated with the air outlet duct 19.

[0102] One end of the air outlet chamber close to the air inlet chamber 171 is located at the upper end of the air inlet chamber 171, reducing the swirl of the indoor air in the air supply duct 17 in the air inlet chamber 171, thereby reducing the energy loss of the air supply air flow and increasing the air supply volume and efficiency.

[0103] The air conditioner of this embodiment reduces the difficulty of processing without affecting the effect of the nozzle structure by providing two sections of air ducts 17 with different aperture sizes, thereby improving processing efficiency and reducing processing costs.

[0104] In a specific embodiment, referring to Figure 3 , Figure 4Each air induction duct 172 of each air outlet cavity is a cylindrical hole that tapers from the air inlet cavity 171 to the air outlet duct 19.

[0105] In a specific embodiment, referring to Figure 3 , Figure 4 Each air duct 172 of the air outlet cavity includes a first aperture section 173 and a second aperture section 174 .

[0106] The diameter of the first aperture section 173 is larger than the diameter of the second aperture section 174. One end of the first aperture section 173 is connected and communicated with the air inlet cavity 171, and the other end is connected and communicated with one end of the second aperture section 174; the other end of the second aperture section 174 is connected and communicated with the air outlet duct 19.

[0107] One end of the air outlet chamber close to the air inlet chamber 171 is located at the upper end of the air inlet chamber 171, reducing the swirl of the indoor air in the air supply duct 17 in the air inlet chamber 171, reducing the energy loss of the air supply air flow, and increasing the air supply volume and air supply efficiency.

[0108] The air conditioner of this embodiment reduces the difficulty of processing by providing two sections of air ducts 172 with different diameters without affecting the effect of the nozzle structure, thereby improving the processing efficiency and reducing the processing cost.

[0109] In a specific embodiment, referring to Figure 3 , Figure 4 The air outlet cavity includes an air outlet section, which is a first aperture section 173 and a second aperture section 174 or the entire second aperture section 174 or a partial section of the second aperture section 174 close to one end of the air outlet duct 19 .

[0110] The air outlet section is an inclined downward channel structure, so that the angle between the airflow direction of the indoor air for air supply flowing out through the air outlet section and the flow direction of the airflow of the heated or cooled indoor air flowing in the air outlet duct 19 is an acute angle, thereby reducing the offset and loss of kinetic energy or potential energy of the airflow of the heated or cooled indoor air flowing in the air outlet duct 19 by the air supply air flowing out of the air supply duct 17, thereby improving the air outlet efficiency and air outlet speed, enhancing user experience and saving energy.

[0111] The outlet section of the curved downward structure forms an acute angle between the outlet direction and the temperature-controlled air supply direction in the outlet duct 19, thereby improving the Bernoulli effect, increasing the outlet velocity of the make-up air at the outlet of the make-up air duct 17, and improving the air mixing effect.
