Description

Technical Field

[0001] This utility model belongs to the field of air conditioning, specifically relating to a wall-mounted air conditioner with a hot air duct. Background Technology

[0002] Because hot air rises, when split-type wall-mounted air conditioners blow out hot air in winter, it often blows towards the upper part of the body, making the head feel hot while the feet feel cold, causing discomfort and a poor user experience. In summer, the wall-mounted air conditioner produces a lot of condensate water containing a lot of cooling energy, but it is discharged outdoors, which is a waste. Summary of the Invention

[0003] The purpose of this utility model is to provide a wall-mounted air conditioner with a hot air duct. The hot air duct outlet is on the ground. When the wall-mounted air conditioner delivers hot air in winter, it blows towards the lower part of the human body to make the human body comfortable. At the same time, the hot air duct has a radiant panel, which uses the low temperature air conditioner condensate to form cold radiation in the room.

[0004] The solution of this utility model is as follows: A wall-mounted air conditioner with a hot air duct includes a wall-mounted unit and a hot air duct. The wall-mounted unit has an upper air inlet and a lower air outlet. The upper part of the hot air duct is connected to the lower air outlet of the wall-mounted unit. It is integrally connected to the wall-mounted unit housing or separately connected. The hot air duct has a cold air outlet and a hot air outlet. The cold air outlet is located at the upper part of the hot air duct, horizontally corresponding to and connected to the lower air outlet of the wall-mounted unit. The cold air outlet has a damper. The bottom of the hot air duct rests on the floor, and a hot air outlet is installed at its bottom. The front panel of the hot air duct is a radiant panel for collecting air conditioner condensate. It includes a water inlet, an air conditioner condensate chamber, an overflow chamber, a water outlet, a condensate collection tank, a condensate collection trough, a condensate main outlet, a cleaning port, an outer panel, an inner panel, a bottom panel, a top panel, an overflow baffle, a right side panel, and a left side panel. The outer panel is the outer side panel (front panel) of the hot air duct. The inner panel is the inner side panel of the hot air duct. The bottom panel is at the bottom of the radiant panel, the top panel is at the top of the radiant panel, the right side panel is on the right side of the radiant panel, and the left side panel is on the left side of the radiant panel. The outer panel, inner panel, bottom panel, overflow baffle, and left side panel (or right side panel) form the air conditioner condensate water chamber. Its inlet is installed at the top and is connected to the condensate pipe of the wall-mounted unit. The overflow baffle is spaced apart from the right side panel (or left side panel) and its bottom is sealed on the bottom panel. Together with the outer panel, inner panel, and right side panel (or left side panel), it forms the overflow chamber. The top of the overflow baffle is spaced apart from the top panel to form an overflow outlet. There is an outlet at the bottom of the overflow chamber. There are condensate water collection tanks on the inner and outer sides of the bottom of the radiant panel. A condensate water collection tank is installed at one end of the bottom of the radiant panel. The outlet, condensate water collection tank and condensate water collection tank are connected. A total condensate water outlet is connected to the condensate water collection tank. A cleaning port is installed at the bottom of the air conditioner condensate water chamber.

[0005] When supplying cool air in summer, the cold air outlet valve at the top of the hot air duct opens, allowing indoor return air to enter through the upper air inlet of the wall-mounted unit. After being cooled and dehumidified, the air is then discharged through the lower air outlet and back through the cold air outlet at the top of the hot air duct, directing air upwards and away from people to avoid being exposed to cold air. The heat exchanger of the wall-mounted unit generates 16°C low-temperature condensate, which flows into the air conditioner's condensate chamber from the inlet of the radiant panel. The low-temperature condensate radiates cold air into the room through the front panel, cooling the air. The low-temperature condensate circulates and mixes within the condensate chamber, gradually increasing in temperature. Once full, it flows into the overflow chamber from the overflow outlet at the top of the overflow baffle and into the condensate collection tank from the bottom outlet. Simultaneously, the low-temperature condensate cools and dehumidifies the indoor air through the radiant panel, causing condensation on both the inside and outside of the panel. This condensate flows down the panel surface into the condensate collection tank at the bottom, and finally, all the condensate is discharged outdoors through the main condensate outlet.

[0006] When hot air is supplied in winter, the cold air outlet valve at the top of the hot air duct is closed. The indoor return air enters from the upper air inlet of the wall-mounted unit, is heated, and is sent out from the lower air outlet. Due to the obstruction of the cold air outlet valve, the hot air is blown downward into the hot air duct and blown into the room from the bottom hot air outlet, forming floor-level hot air supply. At the same time, the radiant panel of the hot air duct plays a role in heat radiation, making the legs of the human body feel comfortable.

[0007] Therefore, it avoids the problem of cold air blowing on the body in summer and hot air blowing on the head in winter, makes full use of the air conditioner's condensate, improves comfort, and achieves the goal of energy saving. Moreover, the equipment is simple and easy to implement. Attached Figure Description

[0009] Figures 1 to 9 The wall-mounted air conditioner with a hot air duct includes a wall-mounted unit 1 and a hot air duct 4. The wall-mounted unit 1 has an upper air inlet 2 and a lower air outlet 3. The upper part of the hot air duct 4 is connected to the lower air outlet 3 of the wall-mounted unit 1. It is integrally connected to the casing of the wall-mounted unit 1 or separately connected. The hot air duct 4 has a cold air outlet 5 and a hot air outlet 7. The cold air outlet 5 is located at the upper part of the hot air duct 4, horizontally corresponding to and connected to the lower air outlet 3 of the wall-mounted unit 1. The cold air outlet 5 has a damper 6. The bottom of the hot air duct 4 rests on the floor, and the hot air outlet 7 is installed at its bottom. The front panel of the hot air duct 4 is a radiant panel for collecting air conditioner condensate, located between the cold air outlet 5 and the hot air outlet 7. Figures 1 to 5It includes an inlet 9, an air conditioning condensate chamber 8, an overflow chamber 10, an outlet 16, a condensate collection trough 19, a condensate collection trough 17, a condensate main outlet 18, a cleaning port 20, an outer panel 21, an inner panel 22, a bottom panel 13, a top panel 14, an overflow baffle 15, a right side panel 11, and a left side panel 12. The outer panel 21 is the outer side panel (front panel) of the hot air duct 4, the inner panel 22 is the inner side panel of the hot air duct 4, the bottom panel 13 is at the bottom of the radiant panel, the top panel 14 is at the top of the radiant panel, the right side panel 11 is on the right side of the radiant panel, and the left side panel 12 is on the left side of the radiant panel. The air conditioning condensate chamber 8 is formed by the outer panel 21, the inner panel 22, the bottom panel 13, the overflow baffle 15, and the left side panel 12 (or the right side panel 11). 9 is installed on its upper part and connected to the condensate pipe of the wall-mounted unit 1. The overflow baffle 15 is spaced apart from the right side plate 11 (or the left side plate 12). The bottom is sealed on the bottom plate 13 and forms an overflow chamber 10 with the outer plate 21, inner plate 22, and right side plate 11 (or left side plate 12). The top of the overflow baffle 15 is spaced apart from the top plate 14 to form an overflow outlet. There is a water outlet 16 at the bottom of the overflow chamber 10. There are condensate water collection tanks 19 on the inner and outer sides of the bottom of the radiant plate. A condensate water collection tank 17 is installed at one end of the bottom of the radiant plate. The water outlet 16, the condensate water collection tank 19 and the condensate water collection tank 17 are connected. A condensate water main outlet 18 is connected to the condensate water collection tank 17. A cleaning port 20 is installed at the bottom of the air conditioner condensate water chamber 8.

[0010] The hot air duct 4 should preferably be made of metal to facilitate radiation from the radiant panel. The distance between the outer panel 21 and the inner panel 22 of the air conditioner condensate chamber 8 should preferably be between 2 and 5 millimeters. The width and thickness of the hot air duct 4 are determined according to the dimensions of the wall-mounted unit 1. It is not limited to the construction form of the cold air outlet 5 shown in the figure; other types of air outlets can also be used.

[0011] When supplying cool air in summer, the damper 6 of the cold air outlet 5 at the top of the hot air duct 4 opens, and the indoor return air enters from the upper air inlet 2 of the wall-mounted unit 1. After being cooled and dehumidified, it is sent out from the lower air outlet 3 and then sent into the room through the cold air outlet 5 at the top of the hot air duct 4, and then sent to a distant and high place. When the blades of the damper 6 are placed horizontally, there is a gap between its rear end and the lower air outlet 3. The cold air blows out from the lower air outlet 3 and is sent forward along the blades of the damper 6. A negative pressure is formed at the gap, which draws in the air in the hot air duct 4 and introduces the high-temperature indoor air from the hot air outlet 7 into the hot air duct 4. It is then mixed with the low-temperature cold air processed by the wall-mounted unit 1 and reheated, which increases the supply air temperature and avoids people being blown by cold air. The heat exchanger of the wall-mounted unit 1 generates low-temperature condensate at 16°C, which flows into the air conditioner condensate chamber 8 from the inlet 9 of the radiant panel. The low-temperature condensate radiates cold radiation into the room through the front panel (outer panel 21), which has a cooling effect. The low-temperature condensate circulates and mixes heat in the air conditioner condensate chamber 8, and the temperature gradually increases. When it is full, it flows into the overflow chamber 10 from the overflow port at the top of the overflow baffle 15, and into the condensate collection tank 17 from the outlet 16 at the bottom. At the same time, the low-temperature condensate radiates cold radiation into the human body through the radiant panel, which cools and dehumidifies the indoor air. Condensate is generated on both the inner and outer sides of the radiant panel, and flows down the panel surface into the condensate collection tank 19 at the bottom, and then into the condensate collection tank 17. Finally, all the condensate is discharged to the outside from the condensate main outlet 18.

[0012] When hot air is supplied in winter, the air valve 6 of the cold air outlet 5 at the top of the hot air duct 4 is closed. The indoor return air enters from the upper air inlet 2 of the wall-mounted unit 1, is heated, and is sent out from the lower air outlet 3. Due to the obstruction of the air valve 6 of the cold air outlet 5, the hot air blows downward into the hot air duct 4 and blows into the room from the bottom hot air outlet 7, forming floor-level hot air supply. At the same time, the radiant panel of the hot air duct 4 plays a role in heat radiation, making the legs of the human body feel comfortable.

[0013] Figure 6In the middle, the front panel of the hot air duct 4 is another type of radiant panel that accommodates air conditioning condensate. It includes an inlet 9, an air conditioning condensate chamber 8, an outlet 16, a condensate sump 19, a condensate collection trough 17, a condensate main outlet 18, an outer panel 21, an inner panel 22, a bottom panel 13, a top panel 14, a right side panel 11, and a left side panel 12. The outer panel 21 is the outer side panel (front panel) of the hot air duct 4, the inner panel 22 is the inner side panel of the hot air duct 4, the bottom panel 13 is at the bottom of the radiant panel, the top panel 14 is at the top of the radiant panel, the right side panel 11 is on the right side of the radiant panel, and the left side panel 12 is on the left side of the radiant panel. The left side panel 12 forms the air conditioner condensate chamber 8, with its inlet 9 installed at the top and connected to the condensate pipe of the wall-mounted unit 1. An outlet 16 is installed at its bottom, and one or more horizontal baffles 23 are installed inside to form a serpentine condensate flow channel. There are condensate collection tanks 19 on the inner and outer sides of the bottom of the radiant panel, and a condensate collection tank 17 is installed at one end of the bottom of the radiant panel. The outlet 16, the condensate collection tank 19 and the condensate collection tank 17 are connected. A condensate main outlet 18 is connected to the condensate collection tank 17. An overflow observation port 24 is installed on the right side panel 11 or the left side panel 12 between the top panel 14 of the radiant panel and the horizontal baffle 23. When supplying cold air in summer, first block the outlet 16. Low-temperature condensate flows from the inlet 9 into the air conditioner condensate chamber 8. When the water in the air conditioner condensate chamber 8 is full to the overflow observation port 24, open the outlet 16 to allow the air conditioner condensate to flow out normally. In this way, the 16°C low-temperature condensate flows down the serpentine condensate channel formed by the horizontal baffle 23, constantly turning and radiating into the room. The temperature of the air conditioner condensate continuously rises and flows into the condensate collection tank 17 through the outlet 16. At the same time, the low-temperature condensate cools and dehumidifies the indoor air through the radiant plate, producing condensate on both the inside and outside of the radiant plate. It flows down the plate surface into the condensate collection tank 19 at the bottom and converges into the condensate collection tank 17. Finally, all the condensate is discharged to the outside from the condensate main outlet 18. When the air conditioner condensate chamber 8 is full of condensate, the opening size of the outlet 16 should ensure that the amount of condensate flowing in from the inlet 9 is balanced with the amount of condensate flowing out from the outlet 16, so as to keep the condensate chamber full and form the maximum amount of cold radiation.

[0014] Figure 7 , 8 In the middle, the radiant panel uses an inflatable plate 25, with an inflatable tube 26 on its surface. This tube carries the air conditioner's condensate water. Its upper inlet 9 connects to the condensate pipe of the wall-mounted unit 1, and its lower outlet 16 connects to the condensate collection tank 17. The inflatable tube 26 is... Figure 7In the horizontal serpentine pipe, the air conditioning condensate flows horizontally from top to bottom into the condensate collection tank 17. The low-temperature air conditioning condensate exchanges heat with the indoor air through the expansion plate 25 and expansion pipe 26. The air is cooled, and condensate is generated on the plate surface, flowing into the condensate collection tank 19 at the bottom. There are condensate collection tanks 19 on the inner and outer sides of the bottom of the radiant plate, and the condensate collection tank 17 is installed at one end of the bottom of the radiant plate. The outlet 16, the condensate collection tank 19 and the condensate collection tank 17 are connected. The condensate collection tank 17 is connected to the condensate main outlet 18. The expansion pipe 26 can also be... Figure 8 The system has multiple vertical pipes, with the upper end connected to a horizontal water distribution pipe. The inlet 9 is connected to the condensate pipe of the wall-mounted unit 1, and the lower end is connected to a horizontal water collection pipe. The outlet 16 is connected to the condensate collection tank 17. The condensate from the low-temperature air conditioner flows through multiple vertical pipes and exchanges heat with the indoor air through the expansion plate 25 and expansion pipe 26. The air is cooled, and condensate is generated on the plate surface, flowing into the condensate collection tank 19 at the bottom.

[0015] Figures 1 to 9 The wall-mounted unit 1 can be the indoor unit of a split air conditioner, or the terminal unit of a multi-split system, in which the heat exchanger is supplied with refrigerant, or the terminal unit of an air conditioning water system, in which the heat exchanger is supplied with hot and cold water.

[0016] Figure 10 , 11 The wall-mounted air conditioner with a hot air duct includes a heat exchanger 32, a heat exchanger cavity 31, a cross-flow air cooler 28, a cross-flow hot air fan 35, a hot air duct 33, a cold air outlet 27, a secondary return air inlet 29, a mixing chamber 30, a primary return air inlet 34, and a hot air outlet 36. The heat exchanger 32 is installed inside the heat exchanger cavity 31, with its upper air outlet connected to the mixing chamber 30 and its lower air outlet connected to the hot air duct 33. A secondary return air inlet is installed on the side of the mixing chamber 30. The upper part of the duct 29 connects to the air duct of the cross-flow air cooler 28. Above the air duct of the cross-flow air cooler 28 is the cold air outlet 27. The upper part of the hot air duct 33 connects to the heat exchanger cavity 31, and the lower part is equipped with a primary return air inlet 34, which is connected to the air duct of the cross-flow hot air fan 35. The hot air outlet 36 is located on the ground and connects to the air duct of the cross-flow hot air fan 35. The front panel of the hot air duct 33 is a radiant plate, which is located between the heat exchanger cavity 31 and the primary return air inlet 34. Its structure is the same as... Figure 3 , 4 The structure of the radiating plates 5, 6, 7, and 8.

[0017] When supplying cool air in summer, the cross-flow air cooler 28 starts, the cross-flow hot air fan 35 stops, and the cold air outlet 27, secondary return air inlet 29, and primary return air inlet 34 open. Under the suction of the cross-flow air cooler 28, the indoor return air enters the hot air duct 33 through the primary return air inlet 34, hot air outlet 36, and cross-flow hot air fan 35. In the heat exchanger chamber 31, it is cooled and dehumidified by the heat exchanger 32, and then enters the mixing chamber 30. A portion of the indoor secondary return air also enters the mixing chamber 30 under the suction of the cross-flow air cooler 28. In this way, the low-temperature cold air processed by the heat exchanger 32 mixes with the indoor secondary return air in the mixing chamber 30, raising the air temperature and achieving the effect of reheating. Finally, it is sent from a high position to a distant part of the room through the cross-flow air cooler 28 and the cold air outlet 27. Because the supply air temperature is increased, the supply air does not feel cold when it falls on people. At the same time, the radiant panel on the front of the hot air duct 33 forms cold radiation to the human body, resulting in a good user experience.

[0018] When hot air is supplied in winter, the cross-flow hot air blower 35 starts, the cross-flow cold air blower 28 stops, the cold air outlet 27 and the secondary return air inlet 29 open, and the primary return air inlet 34 closes. Under the suction of the cross-flow hot air blower 35, the indoor return air enters the heat exchanger chamber 31 from the secondary return air inlet 29, the cold air outlet 27, and the cross-flow cold air blower 28 duct, is heated by the heat exchanger 32, and then enters the hot air duct 33. Finally, it is blown from the ground to the legs of the human body through the cross-flow hot air blower 35 duct and the hot air outlet 36. At the same time, the radiant panel on the front of the hot air duct 33 forms heat radiation to the human body, providing a good user experience.

[0019] This wall-mounted unit can be the indoor unit of a split air conditioner, or the terminal unit of a multi-split system, with refrigerant flowing through its heat exchanger 32. Alternatively, it can be the terminal unit of an air conditioning water system, with chilled and hot water flowing through its heat exchanger 32. It is a floor-standing, ultra-thin wall-mounted unit with a casing thickness of approximately 150 mm. The heat exchanger 32 can be a single straight-plate finned heat exchanger, installed at an angle, or two to three blown-plate heat exchangers, installed vertically, or a microchannel heat exchanger. The inner wall of the heat exchanger cavity 31 should be insulated.

[0020] Figure 12 , 13 The wall-mounted air conditioner with a hot air duct includes a heat exchanger 32, a heat exchanger cavity 31, a cross-flow fan assembly 37, a hot air duct 33, a secondary return air inlet 29, and a mixing chamber 30. The heat exchanger 32 is installed inside the heat exchanger cavity 31, with its upper air inlet connected to the mixing chamber 30 and its lower air inlet connected to the hot air duct 33. The mixing chamber 30 has a secondary return air inlet 29 on its side, with its upper part connected to the cross-flow fan assembly 37 duct in summer and to the indoor return air in winter. The hot air duct 33 has its upper part connected to the lower part of the heat exchanger cavity 31, and its lower part connected to the indoor return air in summer and to the cross-flow fan assembly 37 duct in winter. The front panel of the hot air duct 33 is a radiant panel located below the heat exchanger cavity 31, and its structure is the same as... Figure 3 , 4 The structure of the radiating plates 5, 6, 7, and 8.

[0021] The cross-flow fan assembly 37 includes a housing, a cross-flow fan, an air inlet, and an air outlet. It is detachable and movable. In summer, it is installed on the upper part of the mixing chamber 30 to deliver cool air to the room. In winter, it is removed and installed on the lower part of the hot air duct 33 to deliver hot air to the room, which can save one cross-flow fan. The cross-flow fan assembly 37 has electrical plugs, and corresponding electrical sockets are installed in the lower part of the mixing chamber 30 and the hot air duct 33 to connect the main power supply and the control board.

[0022] When supplying cool air in summer, the cross-flow fan assembly 37 is installed on the upper part of the mixing chamber 30. The cross-flow fan starts, and the secondary return air vent 29 opens. Under the suction of the cross-flow fan, the indoor return air enters from the lower part of the hot air duct 33. It is cooled and dehumidified by the heat exchanger 32 in the heat exchanger chamber 31, and then enters the mixing chamber 30. A portion of the indoor secondary return air also enters the mixing chamber 30 under the suction of the cross-flow fan. In this way, the low-temperature cold air processed by the heat exchanger 32 mixes with the indoor secondary return air in the mixing chamber 30, and the air temperature rises, which plays a role in reheating. Finally, it is sent from a high place to a distant part of the room through the cross-flow fan assembly 37. Because the supply air temperature is increased, there is no cold air feeling when the supply air falls on people. At the same time, the radiant panel on the front of the hot air duct 33 forms cold radiation to the human body, resulting in a good user experience.

[0023] When hot air is supplied in winter, the cross-flow fan assembly 37 is installed at the lower part of the hot air duct 33. When the cross-flow fan is started, the secondary return air port 29 is opened or closed. Under the suction of the cross-flow fan, the indoor return air first enters the mixing chamber 30 from the upper part of the mixing chamber 30 and the secondary return air port 29, then enters the heat exchanger chamber 31, is heated by the heat exchanger 32, and then enters the hot air duct 33. Finally, it is blown from the ground to the legs of the human body through the cross-flow fan assembly 37. At the same time, the radiant panel on the front of the hot air duct 33 forms heat radiation to the human body, resulting in a good user experience.

[0024] Figure 14 The wall-mounted air conditioner with a hot air duct includes a wall-mounted unit 1 and a flexible hot air duct 42, characterized in that the flexible hot air duct... The flexible hot air duct 42 is made of a flexible, airtight material. Its upper opening is an elastic opening made of elastic band 39 and includes a hanging bracket 38. In winter, the upper opening of the flexible hot air duct 42 is fitted over the air outlet of the wall-mounted unit 1, the elastic band 39 is tightened and sealed to the outer casing of the wall-mounted unit 1, and it is hung on the outer casing of the wall-mounted unit 1 using the hanging bracket 38. A wind deflector 41 is installed at the air outlet of the wall-mounted unit 1 and fixed to the outer casing of the wall-mounted unit 1 with a fastener 40. This prevents the flexible hot air duct 42 from being blown away by the air coming out of the air outlet of the wall-mounted unit 1. The lower part of the flexible hot air duct 42 has a hot air duct outlet end 43, with a hot air outlet 44 on top. It is floor-mounted. This flexible hot air duct 42 is used to deliver hot air in winter and is removed in summer. Its structure is simple, low-cost, and easy to install and use. The aforementioned radiant panel can also be installed on the flexible hot air duct 42.

[0025] Figure 15 ,16 The wall-mounted air conditioner with a hot air duct includes a wall-mounted unit 1 and a retractable hot air duct 45. The retractable hot air duct 45 is characterized in that the upper part of the retractable hot air duct 45 is installed at the air outlet of the cross-flow fan of the wall-mounted unit 1, and the lower part is equipped with an air outlet 46. The air outlet of the cross-flow fan is connected to the air outlet 46 through the retractable hot air duct 45. The retractable hot air duct 45 is made of elastic, airtight material folded or made of multi-segment socket sleeves. When cold air is delivered in summer, the retractable hot air duct 45 retracts, and the air outlet 46 rises to below the wall-mounted unit 1, delivering cold air to a distance from a high position. When hot air is delivered in winter, the retractable hot air duct 45 extends, and the air outlet 46 descends to the ground, delivering hot air to the floor. Figure 15 In the middle, the retractable hot air duct 45 is made of elastic, airtight material through folding. Figure 16 In the middle, the retractable hot air duct 45 is made of multi-section socket sleeves. The air outlet 46 is equipped with movable fan blades, which can adjust the air delivery angle.
