Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an integrated ceiling air conditioner. Background Technology

[0002] With the continuous improvement of living standards, air conditioners have become an important device for improving the comfort of living and working environments. Currently, air conditioners are generally divided into split-type and integrated types, and their heat dissipation methods mostly rely on air-cooling technology.

[0003] Traditional air conditioners typically require openings in the building walls during installation to expel indoor heat through ductwork, thus achieving a cooling effect. However, due to limitations imposed by building structure or safety requirements, existing air conditioners often cannot be installed. Furthermore, many traditional air conditioners typically lack heating capabilities. Therefore, traditional air conditioners suffer from problems such as difficult installation, poor spatial adaptability, and limited functionality. Utility Model Content

[0004] This application provides an integrated ceiling-mounted air conditioner that integrates cooling and heating functions into one unit, achieving the effects of easy installation without drilling and strong space adaptability.

[0005] In a first aspect, embodiments of this application provide an integrated ceiling-mounted air conditioner, which includes:

[0006] The housing is configured to be installed on an indoor ceiling, and the housing has a return air vent, an air outlet, a water inlet, and a drain outlet; the drain outlet is configured to communicate with a sewer pipe.

[0007] An air conditioning component, disposed within the housing, includes a refrigerant circuit for refrigerant flow. When the integrated ceiling air conditioner is in cooling mode, the air conditioning component is configured to start, and the refrigerant is configured to exchange heat with air entering the housing through the return air vent while flowing within the refrigerant circuit, thereby reducing the air temperature. The air conditioning component includes a heat exchanger having a refrigerant flow channel and a cooling flow channel, the refrigerant flow channel being a part of the refrigerant circuit structure. The water inlet is connected to the inlet of the cooling flow channel to provide an external water source to the cooling flow channel, and the outlet of the cooling flow channel is connected to the drain outlet. The external water source is configured to exchange heat with the refrigerant within the refrigerant flow channel while flowing through the cooling flow channel, thereby cooling the refrigerant.

[0008] A fan is configured to direct the cooled or uncooled air to the air outlet;

[0009] The heating element is configured to heat the air that has not cooled down and is flowing toward the air outlet when the integrated ceiling air conditioner is in heating mode.

[0010] This application provides an integrated ceiling-mounted air conditioner, which is installed in the indoor ceiling via a casing, effectively saving installation space. The casing has a return air vent, an air outlet, a water inlet, and a drain outlet. The casing integrates the return air vent, air outlet, water inlet, and drain outlet into one unit. The return air vent and air outlet are used for air circulation, while the water inlet and drain outlet are used for water cooling, providing support for the realization of the integrated ceiling-mounted air conditioner's functions.

[0011] The air conditioning unit is housed within the casing and includes a refrigerant circuit for refrigerant flow. When the integrated ceiling-mounted air conditioner is in cooling mode, the air conditioning unit starts, and indoor air enters the casing through the return air vent. The refrigerant flows along the refrigerant circuit, exchanging heat with the air inside the casing. As the refrigerant temperature rises, the air temperature inside the casing decreases. Driven by the fan, the cooled air inside the casing is then exhausted into the room through the air outlet, thereby cooling the room and achieving a cooling effect.

[0012] The air conditioning components include a heat exchanger with refrigerant and cooling channels. The refrigerant channel is part of the refrigerant circuit. The inlet connects to the inlet of the cooling channel, providing external water to dissipate heat from the refrigerant. The drain connects to the outlet of the cooling channel and also to a drain pipe, providing a discharge path for the heated external water. External water flows into the cooling channel through the inlet. When the refrigerant temperature rises, the external water in the cooling channel exchanges heat with the refrigerant, causing the refrigerant temperature to decrease and the external water temperature to rise. The heated external water flows from the outlet of the cooling channel into the outlet, and then from the drain into the drain pipe, thus achieving water-based cooling. This eliminates the need for drilling holes in the wall for air cooling via ductwork, resulting in simple installation and strong spatial adaptability.

[0013] When the integrated ceiling air conditioner is in heating mode, the air conditioning unit does not start, but the heating element does. The fan draws indoor air into the casing through the return air vent. The air flows through the heating element, where heat exchange occurs, raising the air temperature. The fan then blows the air into the room through the air outlet, further increasing the indoor temperature.

[0014] Therefore, the integrated ceiling air conditioner provided in this application integrates heating and cooling functions into one unit. In cooling mode, the integrated ceiling air conditioner dissipates heat through an external water source and completes heat exchange. The external water source is then directly discharged through the drain pipe. The integrated ceiling air conditioner can be installed without drilling holes in the wall, thus achieving the effects of rich functions, simple installation, no need to modify the building structure, and strong spatial adaptability.

[0015] In one possible implementation, the heating element is located inside the housing and opposite the air outlet.

[0016] In one possible implementation, the projected area of ​​the air outlet on the heating element is located on the heating element.

[0017] In one possible implementation, the heating element is configured to not heat the air flowing toward the air outlet when the integrated ceiling air conditioner is in cooling mode.

[0018] In one possible implementation, the housing has a first mounting cavity and a second mounting cavity, the first mounting cavity having the return air vent and a connecting port, the connecting port connecting to the second mounting cavity; the second mounting cavity has the air outlet.

[0019] The air conditioning component and the fan are located in the first mounting cavity, and the air outlet of the fan is connected to the communication port; the heating element is located in the second mounting cavity.

[0020] In one possible implementation, the housing also has a closable vent configured to communicate with the outside.

[0021] In the ventilation mode, neither the air conditioning component nor the heating element of the integrated ceiling air conditioner is activated, the air outlet is blocked, and the ventilation port is opened; the fan is configured to direct the uncooled air to the area of ​​the casing adjacent to the ventilation port.

[0022] In one possible implementation, the ventilation port and the air outlet are located on two adjacent sides of the housing;

[0023] The integrated ceiling air conditioner also includes a damper, which is rotatably disposed within the housing and is configured to open one of the air outlet and the ventilation inlet and close the other when rotated.

[0024] In one possible implementation, the ventilation port and the air outlet are positioned near the side where the two sides intersect;

[0025] The damper is located between the air exchange port and the air outlet.

[0026] In one possible implementation, the housing has a second mounting cavity, the ventilation port and the air outlet are located on two intersecting sides of the second mounting cavity, and the heating element is disposed in the second mounting cavity and opposite to the air outlet;

[0027] The damper is rotatably mounted on the heating element.

[0028] In one possible implementation, a water flow controller is also included, which is connected between the water inlet and the inlet of the cooling channel, and the water flow controller is also connected to the refrigerant circuit;

[0029] The water flow controller is configured to sense the pressure in the refrigerant circuit and control the opening and closing of the water inlet and the inlet of the cooling channel based on the sensed pressure. Attached Figure Description

[0039] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "electrical connection," etc. (if applicable) should be interpreted broadly. For example, they can refer to a fixed electrical connection, an indirect connection through an intermediate medium, or the internal connection of two components or the interaction between two components.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this application.

[0041] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0042] With the improvement of living standards, air conditioning has become a key device for enhancing life comfort. Existing air conditioners typically use air cooling for heat dissipation and mainly include split-type units with outdoor units and traditional integrated units. Air-cooled air conditioners usually require drilling holes in the wall during installation to transfer the heat generated during cooling to the outside through air ducts. Furthermore, traditional split-type air conditioners with outdoor units typically use heat pump technology for heating, also using air cooling, and similarly require drilling holes in the wall during installation.

[0043] However, current building construction often presents limitations when installing air conditioners. For example, in areas like kitchens and bathrooms, modern buildings typically lack pre-installed platforms for outdoor unit installation or suitable exterior wall surfaces for drilling. Alternatively, for aesthetic or safety reasons, property management often prohibits drilling into exterior walls. These limitations make air conditioner installation difficult, thus failing to meet consumers' cooling needs.

[0044] In addition, many existing all-in-one air conditioners do not have heating functions, which is a problem of limited functionality.

[0045] In summary, there is an urgent need for an air conditioner that integrates cooling and heating functions, can be installed without modifying the building structure, is easy to install, and is highly adaptable to different spaces.

[0046] In view of this, this application provides an integrated ceiling-mounted air conditioner, which is installed in the indoor ceiling via a housing 100, effectively saving installation space. The housing 100 has a return air inlet 110, an air outlet 120, a water inlet 130, and a drain outlet 140. The housing 100 integrates the return air inlet 110, the air outlet 120, the water inlet 130, and the drain outlet 140 into one unit. The return air inlet 110 and the air outlet 120 are used for air circulation, and the water inlet 130 and the drain outlet 140 are used for water cooling, providing support for the realization of the integrated ceiling-mounted air conditioner's functions.

[0047] The air conditioning component 200 is housed within the casing 100 and includes a refrigerant circuit 210 for refrigerant flow. When the integrated ceiling air conditioner is in cooling mode, the air conditioning component 200 is activated. Indoor air enters the casing 100 through the return air vent 110. The refrigerant flows along the refrigerant circuit 210, exchanging heat with the air inside the casing 100. The refrigerant temperature rises, and the air temperature inside the casing 100 decreases. Driven by the fan 300, the cooled air inside the casing 100 is exhausted into the room through the air outlet 120, thereby cooling the room and achieving a cooling effect.

[0048] The air conditioning component 200 includes a heat exchanger 220, which has a refrigerant flow channel and a cooling flow channel. The refrigerant flow channel is part of the refrigerant circuit 210. The inlet 130 is connected to the inlet 221 of the cooling flow channel, providing external water to the cooling flow channel for heat dissipation from the refrigerant. The drain 140 is connected to the outlet 222 of the cooling flow channel and is also connected to a drain pipe, which provides a discharge channel for the external water after its temperature rises. External water flows into the cooling flow channel through the inlet 130. When the refrigerant temperature rises, the external water in the cooling flow channel exchanges heat with the refrigerant in the refrigerant flow channel, causing the refrigerant temperature to decrease and the external water temperature to increase. The heated external water flows into the outlet through the outlet 222 of the cooling channel, and then into the drain pipe through the drain outlet 140, thus achieving water cooling heat dissipation. There is no need to drill holes in the wall to achieve air cooling heat dissipation through the air duct, which achieves the effect of simple installation and strong space adaptability.

[0049] When the integrated ceiling air conditioner is in heating mode, the air conditioning unit 200 does not start, but the heating element 400 starts. The fan 300 draws indoor air into the casing 100 through the return air vent 110. The air flows through the heating element 400, where heat exchange occurs, raising the air temperature. The fan 300 then blows the air into the room through the air outlet 120, further increasing the indoor temperature.

[0050] Therefore, the integrated ceiling air conditioner provided in this application integrates heating and cooling functions into one unit. In cooling mode, the integrated ceiling air conditioner dissipates heat through an external water source and completes heat exchange. The external water source is then directly discharged through the drain pipe. The integrated ceiling air conditioner can be installed without drilling holes in the wall, thus achieving the effects of rich functions, simple installation, no need to modify the building structure, and strong spatial adaptability.

[0051] The following description, in conjunction with the accompanying drawings and embodiments, further elaborates on an integrated ceiling air conditioner provided in this application.

[0052] See Figure 1 This application provides an integrated ceiling air conditioner, which includes a housing 100, an air conditioning component 200, a fan 300, and a heating element 400.

[0053] The housing 100 is designed to be installed on the ceiling indoors. The housing 100 has a return air vent 110, an air outlet 120, a water inlet 130, and a drain outlet 140. The drain outlet 140 is configured to connect to a drain pipe. The return air vent 110 draws in indoor air, which is cooled or heated within the housing 100. The cooled or heated air is then exhausted into the room through the air outlet 120, thus maintaining a comfortable indoor temperature. The housing 100 is the main support for the return air vent 110, air outlet 120, water inlet 130, and drain outlet 140. Installed on the ceiling, the housing 100 interacts with the indoor environment through these components, meeting indoor temperature requirements while improving aesthetics and space utilization.

[0054] When the integrated ceiling air conditioner is in cooling mode, it generates heat while cooling the air inside the casing 100. The water inlet 130 introduces external water to cool the air conditioner. The heated external water is then discharged into the sewer system through the drain outlet 140. The water inlet 130 and drain outlet 140 can be directly integrated with the building's piping system.

[0055] For example, the water inlet 130 can be integrated with the building's water supply pipes, such as the tap water pipes in the kitchen or bathroom, to provide water-cooled heat dissipation for the integrated ceiling air conditioner. The drain outlet 140 is directly integrated with the sewer pipe, allowing the heat-absorbing tap water to be discharged directly through the sewer pipe, so that the integrated ceiling air conditioner can complete the discharge without the need for a separate drain pump.

[0056] By integrating the inlet 130 and outlet with the building piping system, the installation process of integrated ceiling air conditioners is simplified. The heat dissipation requirements of integrated ceiling air conditioners can be met without drilling holes in the wall, and it has a strong spatial adaptability.

[0057] Air conditioning component 200 is disposed within housing 100. Air conditioning component 200 includes a refrigerant circuit 210 for refrigerant flow. When the integrated ceiling air conditioner is in cooling mode, air conditioning component 200 is configured to start, and the refrigerant is configured to exchange heat with the air entering housing 100 through return air vent 110 when flowing in refrigerant circuit 210, thereby reducing the air temperature. Air conditioning component 200 includes heat exchanger 220, which has refrigerant flow channel and cooling flow channel. The refrigerant flow channel is part of the structure of refrigerant circuit 210. Water inlet 130 is connected to inlet 221 of cooling flow channel to provide external water source to cooling flow channel. Cooling flow channel outlet 222 is connected to drain outlet 140. External water source is configured to exchange heat with refrigerant in refrigerant flow channel when flowing through cooling flow channel to cool refrigerant.

[0058] For example, when the indoor temperature needs to be lowered, the integrated ceiling air conditioner is in cooling mode, the air conditioning unit 200 is activated, and indoor air enters the casing 100 through the return air vent 110. The refrigerant flows in the refrigerant circuit 210, and the air inside the casing 100 exchanges heat with the refrigerant. The refrigerant absorbs heat, the air temperature decreases, and thus the indoor temperature decreases.

[0059] The integrated ceiling air conditioner also includes a heat exchanger 220, which has refrigerant channels and cooling channels. The heat exchanger 220 is a water-cooled heat exchanger. Water-cooled heat exchangers 220 typically divide their internal channels into refrigerant channels and cooling channels through metal (e.g., copper, stainless steel, titanium) walls, allowing heat to be transferred through the metal walls while simultaneously preventing the fluids in the refrigerant and cooling channels from mixing.

[0060] The water inlet 130 is connected to the inlet 221 of the cooling channel, and the drain outlet 140 is connected to the outlet 222 of the cooling channel. Air inside the casing 100 exchanges heat with the refrigerant, absorbing heat and increasing its temperature. External water flows into the cooling channel through the water inlet 130. As the refrigerant flows through the cooling channel, it exchanges heat with the external water, causing its temperature to decrease. The decreased refrigerant temperature leads to an increased external water temperature, which is then discharged directly into the drain pipe through the drain outlet 140.

[0061] By using an external water source to dissipate heat from the refrigerant, the heat can be quickly carried away, which helps to improve heat dissipation efficiency. This maintains the pressure in the refrigerant flow channel within a safe range, preventing the integrated ceiling air conditioner from being damaged due to overheating and high pressure, and ensuring the normal operation of the integrated ceiling air conditioner.

[0062] Furthermore, the inlet 130 is connected to the tap water pipe, and the drain pipe is connected to the sewer pipe, so heat dissipation can be achieved without drilling holes in the wall, making installation simple and highly adaptable to different spaces.

[0063] The fan 300 is configured to direct cooled or uncooled air to the air outlet 120. Air enters the housing 100 through the return air inlet 110, and the fan 300 generates suction during operation, gathering the air. Specifically, when the integrated ceiling air conditioner is in cooling mode, the suction of the fan 300 gathers the cooled air. When the integrated ceiling air conditioner is in heating mode, the suction of the fan 300 gathers the uncooled air, thus forming a concentrated, directional, and stable airflow. The airflow is guided by the thrust generated by the fan 300 and blown to the air outlet 120, discharged into the room, or used to prepare for heating.

[0064] The heating element 400 is configured to heat the uncooled air flowing towards the air outlet 120 when the integrated ceiling air conditioner is in heating mode. When the integrated ceiling air conditioner is in heating mode, the fan 300 blows the untreated air to the air outlet 120, the heating element 400 heats the untreated air, and the heated air is discharged into the room, thereby raising the indoor temperature.

[0065] This application provides an integrated ceiling-mounted air conditioner, which is installed in the indoor ceiling via a housing 100, effectively saving installation space. The housing 100 has a return air inlet 110, an air outlet 120, a water inlet 130, and a drain outlet 140. The housing 100 integrates the return air inlet 110, the air outlet 120, the water inlet 130, and the drain outlet 140 into one unit. The return air inlet 110 and the air outlet 120 are used for air circulation, while the water inlet 130 and the drain outlet 140 are used for water cooling, providing support for the realization of the integrated ceiling-mounted air conditioner's functions.

[0066] The air conditioning component 200 is housed within the casing 100 and includes a refrigerant circuit 210 for refrigerant flow. When the integrated ceiling air conditioner is in cooling mode, the air conditioning component 200 is activated. Indoor air enters the casing 100 through the return air vent 110. The refrigerant flows along the refrigerant circuit 210, exchanging heat with the air inside the casing 100. The refrigerant temperature rises, and the air temperature inside the casing 100 decreases. Driven by the fan 300, the cooled air inside the casing 100 is exhausted into the room through the air outlet 120, thereby cooling the room and achieving a cooling effect.

[0067] The air conditioning component 200 includes a heat exchanger 220, which has a refrigerant flow channel and a cooling flow channel. The refrigerant flow channel is part of the refrigerant circuit 210. The inlet 130 is connected to the inlet 221 of the cooling flow channel, providing external water to the cooling flow channel for heat dissipation from the refrigerant. The drain 140 is connected to the outlet 222 of the cooling flow channel and is also connected to a drain pipe, which provides a discharge channel for the external water after its temperature rises. External water flows into the cooling flow channel through the inlet 130. When the refrigerant temperature rises, the external water in the cooling flow channel exchanges heat with the refrigerant in the refrigerant flow channel, causing the refrigerant temperature to decrease and the external water temperature to increase. The heated external water flows into the outlet through the outlet 222 of the cooling channel, and then into the drain pipe through the drain outlet 140, thus achieving water cooling heat dissipation. There is no need to drill holes in the wall to achieve air cooling heat dissipation through the air duct, which achieves the effect of simple installation and strong space adaptability.

[0068] When the integrated ceiling air conditioner is in heating mode, the air conditioning unit 200 does not start, but the heating element 400 starts. The fan 300 draws indoor air into the casing 100 through the return air vent 110. The air flows through the heating element 400, where heat exchange occurs, raising the air temperature. The fan 300 then blows the air into the room through the air outlet 120, further increasing the indoor temperature.

[0069] Therefore, the integrated ceiling air conditioner provided in this application integrates heating and cooling functions into one unit. In cooling mode, the integrated ceiling air conditioner dissipates heat through an external water source and completes heat exchange. The external water source is then directly discharged through the drain pipe. The integrated ceiling air conditioner can be installed without drilling holes in the wall, thus achieving the effects of rich functions, simple installation, no need to modify the building structure, and strong spatial adaptability.

[0070] In some embodiments, the heating element 400 is located inside the housing 100 and faces the air outlet 120. Untreated air flows over the surface of the heating element 400 driven by the fan 300, exchanging heat with it and rapidly becoming hot air. This hot air, driven by the fan 300, is directly exhausted into the room from the opposite air outlet 120, raising the indoor temperature. The alignment of the heating element 400 with the air outlet 120 creates the shortest path for hot air circulation. This reduces the size of the integrated ceiling-mounted air conditioner while minimizing heat dissipation and retention within the housing 100, achieving energy savings and rapidly increasing the indoor temperature.

[0071] In some embodiments, the projected area of ​​the air outlet 120 on the heating element 400 is located on the heating element 400. Specifically, the projected area of ​​the air outlet 120 on the heating element 400 is less than or equal to the area of ​​the heating element 400, so that when looking into the interior of the housing 100 from the air outlet 120, the line of sight is completely blocked by the heating element 400. When the air inside the housing 100 is discharged from the air outlet 120, it must flow over the surface of the heating element 400 to ensure that all the gas inside the housing 100 exchanges heat with the heating element 400. The fully heated gas is discharged from the air outlet 120, avoiding the mixing of cold air or untreated air and blowing it out, thus improving the thermal energy utilization rate of the heating element 400.

[0072] In some embodiments, the heating element 400 is configured not to heat the air flowing toward the air outlet 120 when the integrated ceiling air conditioner is in cooling mode.

[0073] When the integrated ceiling air conditioner is in cooling mode, the heating element 400 is not activated, and no heat is dissipated. The air inside the casing 100 achieves a cooling effect through heat exchange with the refrigerant. The cooled air first flows over the surface of the non-heating heating element 400, and then is exhausted into the room through the air outlet 120, thus lowering the indoor temperature. By not activating the heating element 400 in cooling mode, it ensures that the air outlet 120 discharges cooled air, avoiding the need for additional cooling capacity to offset the heat generated by the heating element 400 in cooling mode, thus preventing energy waste.

[0074] In some embodiments, the housing 100 has a first mounting cavity 101 and a second mounting cavity 102. The first mounting cavity 101 has a return air vent 110 and a connecting port 150, which connects to the second mounting cavity 102. The second mounting cavity 102 has an air outlet 120. An air conditioning assembly 200 and a fan 300 are disposed in the first mounting cavity 101, and the air outlet of the fan 300 is connected to the connecting port 150. A heating element 400 is disposed in the second mounting cavity 102.

[0075] When the integrated ceiling air conditioner is in cooling mode, the fan 300 draws indoor air into the return air vent 110, thus allowing the air to enter the first mounting cavity 101. Inside the first mounting cavity 101, the air is cooled by the air conditioning component 200, and the fan 300 blows the cooled air from its outlet end towards the connecting port 150. The cooled air then enters the second mounting cavity 102 through the connecting port 150, flows over the surface of the inactive heating element 400, and is then blown into the room through the air outlet 120, thereby lowering the indoor temperature.

[0076] When the integrated ceiling air conditioner is in heating mode, the fan 300 draws indoor air into the return air vent 110, allowing the air to enter the first mounting chamber 101, and then blows the air out through the outlet 150. Untreated air enters the second mounting chamber 102 through the outlet 150. The heating element 400 is activated, and the untreated air flows through the heating element 400, exchanging heat with it, raising the air temperature. The air is then blown into the room through the outlet 120, thus raising the indoor temperature.

[0077] By using the first mounting cavity 101 and the second mounting cavity 102, the cooling process and the heating process are completed in two separate cavities, avoiding mutual energy interference and improving the reliability of the integrated ceiling air conditioner.

[0078] See Figure 2 In some embodiments, the housing 100 also has a closable vent 160 configured to communicate with the outside. In ventilation mode, the integrated ceiling-mounted air conditioner's air conditioning components 200 and heating element 400 are not activated, the air outlet 120 is blocked, and the vent 160 is open. The fan 300 is configured to direct uncooled air to the area of ​​the housing 100 adjacent to the vent 160.

[0079] When the integrated ceiling air conditioner is in ventilation mode, neither the air conditioning unit 200 nor the heating element 400 is activated. The air outlet 120 is blocked, the ventilation vent 160 is opened, and the fan 300 starts. The fan 300 draws indoor air into the casing 100 through the return air vent 110 and then exhausts the indoor air to the outside through the ventilation vent 160. As indoor air is continuously exhausted, a slight negative pressure is created indoors, allowing fresh outdoor air to enter, thus completing the air replacement of the entire room.

[0080] By blocking the air outlet 120, indoor air circulation is prevented, improving the efficiency of air exchange with the outside. The 160-degree ventilation opening allows for the introduction of fresh air into the room while saving energy, improving indoor air quality. Integrated ceiling-mounted air conditioners combine cooling, heating, and ventilation into one unit, saving installation space and costs, and offering strong spatial adaptability.

[0081] In some embodiments, the ventilation port 160 and the air outlet 120 are located on two adjacent sides of the housing 100. The integrated ceiling air conditioner also includes a damper 170, which is rotatably disposed within the housing 100 and is configured to open one of the air outlet 120 and the ventilation port 160 and close the other when rotated.

[0082] When the integrated ceiling air conditioner is in cooling or heating mode, the damper 170 rotates to the ventilation port 160, closing the ventilation port 160 and opening the air outlet 120. Air enters through the return air vent 110, is processed by the air conditioning component 200 or the heating element 400, and is blown out through the air outlet 120, thus completing temperature regulation.

[0083] When the integrated ceiling air conditioner is in ventilation mode, the damper 170 rotates to the ventilation port 160, closing the air outlet 120 and opening the ventilation port 160. Air enters through the return air inlet 110, is guided by the fan 300 to the ventilation port 160, and is then exhausted outdoors through the ventilation port 160, completing the ventilation process.

[0084] The ventilation port 160 and the air outlet 120 are located on two adjacent sides of the housing 100. The opening and closing action can be completed by rotating a damper 170, which saves installation space and cost and improves ventilation efficiency.

[0085] In some embodiments, the air exchange 160 and the air outlet 120 are positioned near the side where the two sides intersect. A damper 170 is located between the air exchange 160 and the air outlet 120. The damper 170 can switch modes by swinging at a small angle, reducing the movement path of the damper 170 and saving internal space in the housing 100. This allows for a further reduction in the size of the integrated ceiling-mounted air conditioner, facilitating installation and providing strong space adaptability.

[0086] In some embodiments, the housing 100 has a second mounting cavity 102, with an air vent 160 and an air outlet 120 located on two intersecting sides of the second mounting cavity 102. A heating element 400 is disposed within the second mounting cavity 102 and faces the air outlet 120. A damper 170 is rotatably mounted on the heating element 400. By integrating the damper 170 onto the heating element 400, the internal structure of the housing 100 becomes more compact, reducing the volume of the integrated ceiling-mounted air conditioner and improving its spatial adaptability.

[0087] In some embodiments, the integrated ceiling air conditioner further includes a water flow controller 230, which is connected between the water inlet 130 and the inlet 221 of the cooling channel, and is also connected to the refrigerant circuit 210. The water flow controller 230 is configured to sense the pressure in the refrigerant circuit 210 and control the opening and closing of the water inlet 130 and the inlet 221 of the cooling channel according to the sensed pressure.

[0088] For example, when the integrated ceiling air conditioner is started in cooling mode, the compressor starts running, the refrigerant is compressed, the refrigerant temperature rises, and the pressure in the refrigerant circuit 210 increases. The water flow controller 230 senses the pressure and connects the water inlet 130 and the inlet 221 of the cooling channel, allowing external water to enter the cooling channel, absorb the heat of the refrigerant, and ensure that the heat exchanger 220 heats up efficiently.

[0089] When the compressor is running continuously, the pressure of the refrigerant circuit 210 is kept at a stable value, and the water flow controller 230 keeps the water inlet 130 connected to the cooling channel inlet to ensure a stable supply of external water to maintain the system's efficient heat dissipation.

[0090] When the integrated ceiling air conditioner is turned off, the compressor stops working, the refrigerant stops circulating and gradually cools down, the pressure in the refrigerant circuit 210 begins to decrease, the water flow controller 230 senses the pressure decrease and cuts off the water inlet 130 and the inlet 221 of the cooling channel, stopping the supply of external water.

[0091] The water flow controller 230 can adjust the supply of external water source according to the actual heat dissipation requirements of the heat exchanger 220, thereby reducing energy consumption and saving water while ensuring the stable operation of the integrated ceiling air conditioner.

[0092] For example, the integrated ceiling air conditioner also includes a detection element and an electronic control module, wherein the detection element includes at least one of a temperature sensor and a pressure sensor.

[0093] When the integrated ceiling-mounted air conditioner is running in cooling mode, the detection device continuously monitors the operating data in the refrigerant circuit 210, such as temperature or pressure, or both. The detection device transmits the detected operating data to the electronic control module, which reads the data and compares it with preset values. When the operating data is greater than or equal to the preset value, the electronic control module determines that the integrated ceiling-mounted air conditioner is in a dangerous state and shuts it down. With the air conditioner off, the heat generated decreases, causing the pressure to drop. The detection device continues to monitor the operating data; when the operating data is less than the preset value, the electronic control module determines that the dangerous state of the integrated ceiling-mounted air conditioner has been resolved and restarts the air conditioner.

[0094] By continuously monitoring operating data through detection devices, abnormalities in the integrated ceiling air conditioner can be detected in a timely manner. When an abnormality occurs, the electrical control module can respond promptly and shut down the unit, reducing the possibility of further damage and preventing safety accidents, thereby improving safety.
