Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioner mainframes, and in particular relates to an air conditioner water heater mainframe fusion body in which an evaporator cavity and an air conditioner exhaust cavity are embedded. Background Art

[0002] See Figures 15 to 17 Now, home central air-conditioning units and air-energy water heaters have become standard configurations on the residential equipment platform of fine-decorated houses.

[0003] Nowadays, the air path structure of the heat exchanger cavity outside the air conditioner main unit is a signature paradigm of "large-area low-speed air intake on the sides and back + medium-speed exhaust from multiple fans on the front + side inlet and side outlet of the air path" facing the open atmospheric environment.

[0004] The home central air-conditioning host and air-energy water heater, which have become standard configurations on the equipment platform of hardcover residential buildings, have the following urgent problems to be solved:

[0005] ① The classic structure of the current home air conditioner host has problems such as poor ventilation and deterioration of air conditioning performance.

[0006] The current household air-conditioning main unit excludes the high-power multi-split top-outlet structure solution and inherits the classic side-outlet structure of room air conditioners. There are serious problems of poor exhaust and deteriorated air-conditioning performance on the equipment platform: in recent years, architects have enhanced the decorativeness of the facades of buildings and equipment platforms. When architects use blinds to hide the air-conditioning main unit on the equipment platform for the visual effect of the building facade, the medium-speed exhaust (below 7m / s) air-conditioning main unit is hindered from exhausting the outdoor atmosphere. The exhaust air passes through the facade blinds and enters the ambient atmosphere, and the diffusion and dilution effect is suppressed. A considerable part of the exhaust air from the external heat exchanger is blocked by the blinds and returns to the equipment platform and is then sucked into the external heat exchanger, causing an air flow short circuit. As a result, the condensing pressure of the air-conditioning main unit is too high during cooling operation in summer, the condensate is insufficiently cooled, and the evaporating pressure is too low during heating operation in winter, and the refrigerant circulation volume is greatly attenuated. The air conditioner cannot fully complete its task as a heat transporter, and the performance of the air-conditioning main unit on the equipment platform is greatly reduced compared with the laboratory data.

[0007] ② The heating efficiency of air-energy water heaters is reduced, especially in low-temperature seasons.

[0008] However, in actual fine-decorated housing projects, the installation positions of the air-source water heater main unit and water tank on the equipment platform are random, and basically they are installed wherever there is a gap, making it even more impossible to focus on solving the problem of environmental ventilation of the water heater main unit's heat-absorbing evaporator.

[0009] However, the heat of the air-energy water heater comes from the air, and the heat released by the condenser of the air-energy water heater is mainly the heat absorbed by the evaporator from the air; the evaporator of the water heater main unit cannot effectively ventilate the ambient atmosphere, causing the evaporator's air to circulate and short-circuit in the small space inside the equipment platform, causing the temperature of the small space of the equipment platform to continue to drop, which in turn further causes the evaporation pressure of the evaporator to decrease and the heating capacity to be seriously attenuated;

[0010] This phenomenon is more serious in low temperature seasons, and the heat pump main unit of the water heater degenerates into an electric heating tube.

[0011] ③ Increase in ineffective and inefficient areas of equipment platforms

[0012] The standard household central air-conditioning main unit and air-energy water heater (including the main unit and water tank) are arranged on the residential equipment platform. Due to the dispersion of the equipment and the need to reserve an air inlet channel for the external heat exchanger at the rear of the air-conditioning main unit and an air inlet and outlet channel for the evaporator of the air-energy water heater main unit, the equipment on the platform is sparse, and the ineffective and inefficient area increases.

[0053] The two heat exchange medium channels of the intermediate heat exchanger are respectively connected to the refrigerant circulation circuit of the air-conditioning main unit and the air-conditioning water circulation circuit of the air-conditioning indoor unit inside the building; the intermediate heat exchanger is a plate heat exchanger, a shell and tube heat exchanger or a sleeve heat exchanger.

[0054] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0055] 1. The air conditioner host and air energy water heater evaporator module are combined into one, with complementary structures, smooth air flow, reduced density of facade exhaust vents, reduced risk of exhaust backflow, and improved heat exchanger performance.

[0056] At present, household air conditioner main units with a capacity of less than 8HP inherit the classic side-outlet structure of room air conditioners. When running on equipment platforms with decorative shutter facades, they encounter serious problems of poor exhaust and deteriorated air conditioning performance: the dynamic pressure head of the medium-speed exhaust air (below 7m / s) of the air conditioner main unit to the atmospheric environment outside the equipment platform is very low. When the architectural designer hides the air conditioner main unit with shutters on the equipment platform for the visual effect of the building facade, the shutters hinder the air conditioner main unit from exhausting. The static pressure of the air conditioner main unit increases, and the exhaust speed and exhaust volume are further reduced. A considerable part of the exhaust air flow is blocked by the shutters and sucked back into the external heat exchanger on the back side of the air conditioner main unit, causing an air flow short circuit. As a result, the condensing pressure of the air conditioner main unit is too high in summer, the condensate is insufficiently cooled, and the evaporating pressure is too low in winter. The refrigerant circulation volume is greatly reduced. The air conditioner cannot fully complete its task as a heat transporter. The performance of the air conditioner main unit on the equipment platform is greatly reduced compared with the laboratory data.

[0057] In one embodiment of the present invention, the inner cavity of the heat exchanger cavity outside the air-conditioning main unit is defined as the negative pressure cavity of the heat exchanger cavity outside the air-conditioning main unit, and the concept of "negative pressure cavity" is injected into the structure of the household air-conditioning main unit and the evaporator module structure of the air-energy water heater, and the air-conditioning main unit compressor, the air-energy water heater compressor and other structures are arranged in the negative pressure cavity of the heat exchanger outside the air-conditioning main unit, and the structural functions other than the air flow channel function in the negative pressure cavity of the heat exchanger outside the air-conditioning main unit are developed to the greatest extent, and all components outside the negative pressure cavity are eliminated; and the exhaust cavity of the heat exchanger outside the air-conditioning main unit is arranged on the top surface of the heat exchanger cavity outside the air-conditioning main unit, and extends to cooperate with the top surface to form an interlocking space between the two, and the air-energy water heater evaporator module is arranged in the interlocking space, and the exhaust outlets of the two are arranged on the same side and adjacent to each other, so as to realize the "two in one, internal concentration, external simplicity, high efficiency and large capacity" of the air-conditioning and water heater main unit structures.

[0058] This embodiment develops and utilizes the empty space (ventilation blind area) in the exhaust chamber of the heat exchanger outside the air-conditioning main unit relative to the exhaust port side, and extends the air-energy water heater evaporator chamber to the empty space, so that the ventilation blind area of ​​the exhaust chamber of the air-conditioning main unit is converted into an effective structural space of the negative pressure chamber of the air-energy water heater evaporator, realizing the structural complementary design of the negative pressure chamber of the air-energy water heater evaporator and the exhaust chamber of the heat exchanger outside the air-conditioning main unit, thereby increasing the air inlet area and heat exchange area of ​​the evaporator chamber of the air-energy water heater.

[0059] In this embodiment, the air conditioner main unit external heat exchanger and the air energy water heater evaporator cavity both introduce fresh air flow from the equipment platform facade through the front and side of the air conditioner main unit shell and the evaporator shell. The fresh air flow flows through the fin gaps on the front and side of the external heat exchanger over a large area at low speed and low resistance to complete heat exchange, and then is sucked in by the fan, accelerated and pressurized, and discharged into the ambient atmosphere in the form of a high-speed jet of about 10m / s for diffusion and dilution. The 10m / s high-speed jet pressure head of this embodiment is twice as high as the traditional 7m / s medium-speed jet pressure head, and its ability to pass through decorative obstacles such as blinds is greatly enhanced.

[0060] In order to solve the problems that the existing equipment platform facade is provided with multiple exhaust vents of the air-conditioning main unit and the air-energy water heater evaporator module, the air inlet surface is fragmented, and the exhaust through the facade is prone to backflow, the exhaust vent of the air-energy water heater evaporator module is arranged on the same side as the exhaust vent of the air-conditioning main unit external heat exchanger exhaust cavity and is adjacent to each other, forming an exhaust vent combination facing the ambient atmosphere outside the equipment platform facade, that is, the exhaust vents of the air-conditioning main unit and the air-energy water heater evaporator module are concentrated and combined, the density of the exhaust vents on the equipment platform facade is reduced, the risk of exhaust backflow is reduced, and the heat exchange performance of the air-conditioning and water heater main unit heat exchangers is improved.

[0061] In this embodiment, the air conditioner main unit and the air energy water heater main unit are not only combined into one, with a simple structure and smooth air path, but also the risk of exhaust backflow on the facade is reduced, and the cooling and heating performance of the main unit is improved, which is close to the laboratory test data.

[0062] 2. Compress inefficient and invalid space and save platform area

[0063] Just as the price of underground parking spaces in properties in first- and second-tier cities has exceeded the price of the vehicles themselves, the price of commercial residential equipment platforms has long surpassed the air conditioners, water heaters and other equipment on the platforms; the economic burden imposed on owners by the ineffective and inefficient areas such as the external heat exchanger air inlet and outlet channels, installation and maintenance space reserved on the equipment platforms is not only a technical issue, but also an economic issue.

[0064] This embodiment addresses the dispersed arrangement of household central air-conditioning main units and air-energy water heaters that have become standard configurations on the equipment platform, as well as the problem of sparse equipment and increased ineffective and inefficient area on the platform due to the reserved air inlet and outlet channels of the heat exchanger outside the air-conditioning main unit and the air-energy water heater evaporator module. By implanting the fluorine path components of the air-conditioning main unit and the air-energy water heater main unit into the negative pressure cavity of the heat exchanger outside the air-conditioning main unit and embedding the air-energy water heater evaporator module into the air-conditioning main unit, a fusion body of the air-energy water heater evaporator module embedded in the air-conditioning main unit is constructed, and the module units are embedded and combined again to construct a more efficient secondary fusion system. In addition, the air intake of the air-conditioning main unit and the air-energy water heater main unit is unified into the back and two side air intakes, and the ambient fresh air is drawn in from the two sides and top of the platform facade, which greatly saves the equipment platform area. While opening up the air path of the heat exchanger outside the air-conditioning main unit and improving the cooling and heating performance, it reduces part of the economic burden on developers and owners.

The air-energy water heater evaporator exhaust cavity 5 is installed in the installation gap, and the air inlet of the air-energy water heater evaporator exhaust cavity 5 is connected to the top surface of the air-energy water heater evaporator cavity 4. That is, the air-energy water heater evaporator cavity 4 and the air-energy water heater evaporator exhaust cavity 5 are stacked from bottom to top and fill the interlocking space. The top surface of the air-energy water heater evaporator exhaust cavity 5 is attached to the bottom surface of the air conditioner main unit's external heat exchanger exhaust cavity 2 on the second installation space portion, and the exhaust vents of the two are arranged on the same side, thereby forming a rectangular exhaust vent combination.

[0096] The air-energy water heater evaporator fan 6 is installed at the exhaust port on the top surface of the air-energy water heater evaporator cavity and is connected to the air-energy water heater evaporator negative pressure cavity and the air-energy water heater evaporator exhaust cavity 5, and is used as a power source for the airflow.

[0097] In this embodiment, the air-energy water heater evaporator chamber 4 may specifically include an evaporator housing 401 and an air-energy water heater evaporator 402. The air-energy water heater evaporator 402 is disposed within the evaporator housing 401 and, together with at least a portion of the evaporator housing 401, forms the air-energy water heater evaporator negative pressure chamber connected to the heat exchange air path of the air-energy water heater evaporator 402. The refrigerant pipeline of the air-energy water heater evaporator 402 is used to connect the air-energy water heater compressor 8 and the internal heat exchange refrigerant pipeline of the air-energy water heater water tank to form at least one set of air-energy water heater refrigerant circulation loops.

[0098] Furthermore, the air-energy water heater evaporator module also includes an air-energy water heater four-way valve 11 and an air-energy water heater expansion valve 12 disposed in the negative pressure chamber of the heat exchanger outside the air conditioner main unit. The air-energy water heater four-way valve 11 and the air-energy water heater expansion valve 12 are disposed on the air-energy water heater refrigerant circulation loop. That is, part of the air-energy water heater refrigerant circulation loop and the air-energy water heater compressor 8, the air-energy water heater four-way valve 11, and the air-energy water heater expansion valve 12 thereon are all located in the negative pressure chamber of the heat exchanger outside the air conditioner main unit. By disposing the air conditioner main unit compressor 7, the air-energy water heater compressor 8, and other structures in the negative pressure chamber of the heat exchanger outside the air conditioner main unit, the structural functions of the negative pressure chamber of the heat exchanger outside the air conditioner main unit are maximized beyond the function of the air flow channel.

[0099] Specifically, the surface of the evaporator shell 401 facing the outside of the equipment room is the front, the surface facing the inside of the equipment room is the back, and the surface away from the exhaust chamber 2 of the heat exchanger outside the air conditioner main unit is the outer side surface. The front, outer side surface and / or back surface of the evaporator shell 401 can be set as the evaporator air inlet surface, and the air-energy water heater evaporator 402 can be a C-shaped fin tube evaporator or an L-shaped fin tube evaporator or a flat-plate fin tube evaporator corresponding to the evaporator air inlet surface.

[0100] In this embodiment, the air conditioner main unit external heat exchanger cavity 1 may specifically include an air conditioner main unit housing 101 and an air conditioner main unit external heat exchanger 102 .

[0101] The side surfaces of the air conditioner housing 101 include a rear panel and at least one air inlet surface. The external heat exchanger 102 is located within the housing 101 and, together with the air inlet surface, forms a negative pressure chamber for the external heat exchanger 102, which connects to the heat exchange air path of the external heat exchanger 102. The refrigerant piping of the external heat exchanger 102 connects the refrigerant piping of the air conditioner's compressor 7 with the refrigerant piping of the air conditioner's internal heat exchanger, forming at least one refrigerant circulation loop for the air conditioner.

[0102] The first installation space and the second installation space are arranged side by side on the top surface of the air conditioner main unit housing 101 in a direction perpendicular to the back surface of the air conditioner main unit, wherein the second installation space corresponds to the back surface of the air conditioner main unit.

[0103] In this embodiment, the exhaust cavity 2 of the heat exchanger outside the air conditioner main unit is an air guide elbow, and the exhaust surface of the air guide elbow is arranged toward the outer facade of the equipment room.

[0104] Specifically, all sides of the air-conditioning main body shell 101 except the back panel surface of the air-conditioning main body can be set as the air inlet surface of the air-conditioning main body shell 101, and the air-conditioning main body external heat exchanger 102 can be a corresponding C-shaped fin tube external heat exchanger or L-shaped fin tube external heat exchanger or flat-plate fin tube evaporator.

[0105] In this embodiment, the air conditioner main unit external heat exchanger fan 3 is an axial flow fan or a centrifugal fan, and the water heater fan is an axial flow fan or a centrifugal fan, which only needs to serve as a power source for the airflow and is not specifically limited here.

[0106] See Figure 4 and Figure 5 Furthermore, the air conditioner main unit also includes a main unit four-way valve 9, an expansion valve 10, and an electrical box, which are located within the negative pressure chamber of the heat exchanger outside the main unit. The four-way valve 9 and expansion valve 10 are located within the main unit's refrigerant circulation loop. The electrical box is mounted on the inner wall of the main unit's back panel, similarly utilizing the ventilation blind area within the negative pressure chamber of the heat exchanger outside the main unit and eliminating all components outside the negative pressure chamber. The relays, controllers, and other components of both the main unit and the air-to-water heater evaporator module are housed within this electrical box.

[0107] See Figure 5 and Figure 6 The following further describes the operation of the air-conditioning air-conditioning water heater host fusion body in which the air-conditioning water heater evaporator cavity 4 and the air-conditioning host exhaust cavity are embedded in this embodiment:

[0108] When the air conditioner main unit of this embodiment is in operation, the air conditioner main unit compressor 7 in the negative pressure chamber of the air conditioner main unit external heat exchanger drives the flow and phase change of the refrigerant in the air conditioner main unit refrigerant circulation loop to absorb and release heat; coupled with the phase change heat transfer of the refrigerant in the fluorine circuit, the air conditioner main unit external heat exchanger fan 3 pushes the air flow through the fin gap of the air conditioner main unit external heat exchanger 102, and implements the heat exchange between the ambient air and the refrigerant in the pipeline of the air conditioner main unit external heat exchanger 102: the air conditioner main unit external heat exchanger fan 3 starts to run, and discharges the air flow to the ambient atmosphere through the upper air guide bend pipe, and at the same time, in the negative pressure chamber of the air conditioner main unit external heat exchanger before the air intake of the air conditioner main unit external heat exchanger fan 3, the air conditioner main unit external heat exchanger blower ... Negative pressure is generated inside; this negative pressure pulls the ambient air to flow through the fin gap of the outdoor heat exchanger 102 of the air conditioner main unit, and exchanges heat with the refrigerant in the tube through the heat-conducting metal fins on both sides of the gap and the metal tube tightly covered by the metal fins. In summer, the ambient air passes through the fins to absorb heat, increase the temperature, and take away heat to ensure that the high-temperature and high-pressure refrigerant gas in the metal tube continues to condense and release heat. In winter, the ambient air passes through the fins to reduce the temperature and release heat to ensure that the low-pressure refrigerant liquid in the metal tube continues to absorb heat and evaporate; the air after heat exchange is pressurized and accelerated by the fan 3 of the outdoor heat exchanger of the air conditioner main unit, and is injected into the ambient atmosphere through the wind guide elbow for diffusion and dilution.

[0109] When the air-energy water heater evaporator module of this embodiment is in operation, the air-energy water heater compressor 8 implanted in the negative pressure cavity of the air-conditioning host drives the flow of the refrigerant in the refrigerant circulation loop of the air-energy water heater and the phase change heat absorption and release; coupled with the phase change heat absorption of the refrigerant in the refrigerant circulation loop of the air-energy water heater, the air-energy water heater evaporator fan 6 in the air-energy water heater evaporator cavity 4 starts to run, and exhausts air to the ambient atmosphere outside the equipment platform through the air-energy water heater evaporator exhaust cavity 5, and simultaneously creates a negative pressure state in the negative pressure cavity of the air-energy water heater evaporator, pulling the ambient air to flow through the air-energy water heater evaporator The fin gap of the evaporator 402 reduces the temperature, filters out water vapor, and releases heat, so as to ensure the continuous evaporation of the low-pressure refrigerant liquid in the refrigerant circulation loop of the air-energy water heater and the continuous condensation and heat release of the high-temperature and high-pressure refrigerant gas in the condenser in the water tank after being pressurized by the air-energy water heater compressor 8 with a continuous heat supply; the air after the fins of the air-energy water heater evaporator 402 release heat is sucked into the negative pressure chamber of the air-energy water heater evaporator and the air-energy water heater evaporator fan 6 after the negative pressure chamber, and the pressure is accelerated, and the air is injected into the ambient atmosphere through the exhaust chamber 5 of the air-energy water heater evaporator for diffusion and dilution.

[0110] In this embodiment, since the fins on the pipelines of the external heat exchanger 102 of the air-conditioning main unit and the evaporator 402 of the air-energy water heater are densely packed and the fin spacing is very small, usually only 1-2 mm, the fin gap becomes the main resistance in the air path of the external heat exchanger and the evaporator; inside the negative pressure cavity of the external heat exchanger of the air-conditioning main unit and the negative pressure cavity of the evaporator of the air-energy water heater, the operation of the fan causes the air pressure to be relatively balanced and relatively low, and an obvious pressure difference is established between the pressure of the ambient air outside the fin-tube heat exchanger; this pressure difference is the driving force for ventilation and heat exchange of the external heat exchanger 102 of the air-conditioning main unit and the evaporator 402 of the air-energy water heater, and is used to overcome the resistance to air flow caused by the fin gap.

[0111] Example 2

[0112] See Figures 7 to 10 This embodiment further improves the structure based on the above embodiment 1, as follows:

[0113] In this embodiment, the arrangement of the exhaust device is adjusted, and the exhaust device may also include an air-energy water heater evaporator exhaust chamber 5 and at least one air-energy water heater evaporator fan 6 .

[0114] The inner cavity of the air energy water heater evaporator cavity 4 is set as the air energy water heater evaporator negative pressure cavity.

[0115] The air-energy water heater evaporator cavity 4 is installed in the embedded space. The air inlet of the air-energy water heater evaporator exhaust cavity 5 is connected to the side of the air-energy water heater evaporator cavity 4 facing the exhaust cavity 2 of the heat exchanger outside the air conditioner main unit. The air-energy water heater evaporator exhaust cavity 5 and the air-energy water heater evaporator cavity 4 are arranged in a transversely fitted manner. The air-energy water heater evaporator exhaust cavity 5 is arranged on the side of the air-energy water heater evaporator cavity 4 away from the first installation space, that is, the air-energy water heater evaporator cavity 4 is wrapped between the air-energy water heater evaporator exhaust cavity 5 and the air conditioner main unit external heat exchanger exhaust cavity 2, and the exhaust vents of the two are arranged on the same side, thereby forming a rectangular exhaust vent combination.

[0116] The air-energy water heater evaporator fan 6 is installed at the outlet of the air-energy water heater evaporator cavity facing outward and is connected to the air-energy water heater evaporator negative pressure cavity and the air-energy water heater evaporator exhaust cavity 5, and is used as a power source for the airflow.

[0117] In this arrangement, the air-energy water heater evaporator 402 may be two flat-plate fin-tube evaporators correspondingly arranged on both sides of the exhaust cavity 5 of the air-energy water heater evaporator.

[0118] Example 3

[0119] See Figures 7 to 10 This embodiment further improves the structure based on the above embodiment 1 or embodiment 2, as follows:

[0120] In this embodiment, the air conditioner main unit's external heat exchanger exhaust chamber 2 is arranged in the first installation space, and at least one empty space 14 is formed within the first installation space, communicating with the second installation space. At least a portion of the air-energy water heater evaporator 402 is embedded in the empty space 14 and coupled to the air conditioner main unit's external heat exchanger exhaust chamber 2, thereby increasing the air intake area and heat exchange area of ​​the air-energy water heater evaporator 402.

[0121] Furthermore, since the shape of the fan is usually circular, the air conditioner main unit external heat exchanger exhaust cavity 2 can also be set to be circular. Therefore, the outer wall surface of the air conditioner main unit external heat exchanger exhaust cavity 2 facing the second installation space is an arc-shaped wall surface.

[0122] The curved wall is connected to the top surface of the heat exchanger cavity 1 outside the air conditioner main unit and divides the first installation space into two empty spaces 14. The two ends of the air energy water heater evaporator 402 in the housing extend and are embedded in the two empty spaces 14 respectively.

[0123] Furthermore, the air-energy water heater evaporator fan 6 is a centrifugal fan, and the air outlet direction of the centrifugal fan is lateral. Therefore, the surface of the air-energy water heater evaporator exhaust chamber 5 facing the top surface of the centrifugal fan is defined as the fan-facing surface. A first preset gap is left between the fan-facing surface and the centrifugal fan to form a uniform one-way exhaust chamber air static pressure exhaust channel between the centrifugal fan and the fan-facing surface. This reduces the static pressure on the closed side (between the centrifugal fan and each side plate of the air-energy water heater evaporator exhaust chamber 5), expands the total exhaust cross-sectional area of ​​the one-way exhaust chamber, thereby promoting the uniformity of the air static pressure field on the open side (the exhaust surface side) and the closed side of the one-way exhaust chamber, increasing the exhaust air volume in the fan-shaped area on the closed side of the impeller, and reducing the fan shaft power.

[0124] Furthermore, each surface of the air-energy water heater evaporator exhaust chamber 5 opposite to the air outlet direction of the centrifugal fan is a side panel, and a second preset interval may also be left between the centrifugal fan and each side panel to form a side panel side exhaust channel between the centrifugal fan and the corresponding side panel, which plays the same role as the first preset interval.

[0125] Example 4

[0126] See Figure 11 Based on the above-mentioned embodiment one, embodiment two or embodiment three, this embodiment further improves the air-conditioning air-energy water heater main unit fusion body in which the air-conditioning water heater evaporator cavity 4 and the air-conditioning main unit exhaust cavity are embedded. The fusion body of this embodiment may also include an intermediate heat exchanger 13.

[0127] This intermediate heat exchanger 13 is located within the negative pressure chamber of the heat exchanger outside the air conditioner main unit. Its two heat exchange medium channels connect the main unit's refrigerant circuit to the building's internal air conditioner water circuit (which can be an indoor fan coil unit, where the refrigerant can be water or another medium). The main unit uses this intermediate heat exchanger 13 to produce hot and cold water, which is then fed into the fan coil units installed indoors to meet the building's cooling and heating needs. In summer, the air conditioner's intermediate heat exchanger 13 produces cold water, which is fed into the fan coil units to absorb heat from the indoor space, achieving cooling. In winter, the main unit uses this intermediate heat exchanger 13 to produce hot water, which is then fed into the fan coil units to heat the indoor air, achieving heating.

[0128] The intermediate heat exchanger 13 may be a plate heat exchanger, a double-tube heat exchanger, or a shell and tube heat exchanger, which is not specifically limited here.

[0129] Since an intermediate heat exchanger 13 is provided in the main unit of the air-conditioning water heater to output hot and cold water for air-conditioning to the indoor fan coil unit to realize cooling in summer and heating in winter, the air-conditioning refrigerant pipeline is confined to the inside of the main unit of the air-conditioning water heater, and its length is greatly shortened, thereby greatly reducing the risk of refrigerant leakage. Furthermore, since the air-conditioning refrigerant pipeline is confined to the main unit of the air-conditioning water heater on the outdoor equipment platform and no longer enters the room, the risk of explosion caused by indoor leakage of refrigerant is eliminated, thereby providing a realistic possibility for the application and promotion of flammable refrigerants such as R290 and R32.

[0130] Example 5

[0131] See Figures 10 to 12 , with regard to the problem that when the air-conditioning air-energy water heater main unit fusion body in the above-mentioned embodiments one, two or three is in operation, the main unit fusion body may still have the problem of exhausting the environment by being sucked into the air-conditioning external heat exchanger below the main unit fusion body exhaust port combination, thereby forming a partial exhaust air flow short circuit. In this embodiment, the side of the air-conditioning main unit shell 101 opposite to the air-conditioning main unit back panel 1011 is set as the back-facing air inlet surface 1012, and the back-facing air inlet surface 1012 faces the inside of the equipment room (the air-conditioning main unit back panel 1011 and the back-facing air inlet surface 1012 are both sides corresponding to the short side of the air-conditioning main unit shell 101); and the air-conditioning main unit back panel 1011 faces the outside of the equipment room, and is located on the same side as the exhaust port (i.e., the exhaust port combination) of the exhaust cavity 2 of the above-mentioned air-conditioning main unit external heat exchanger.

[0132] Furthermore, the exhaust cavity 2 of the heat exchanger outside the air conditioner main unit is an air guide elbow, and the exhaust surface of the air guide elbow is parallel to the back panel surface 1011 of the air conditioner main unit, that is, it is located on the opposite side of the back air inlet surface 1012 to realize back air inlet and forward air exhaust.

[0133] Specifically, the back-to-air inlet surface 1012 of the air conditioner main body housing 101 and one or two side surfaces connected thereto are the air inlet surfaces of the air conditioner main body housing 101, and the air conditioner main body external heat exchanger 102 can be a corresponding C-shaped fin-tube external heat exchanger.

[0134] When the air-conditioning air-energy water heater main unit fusion body of this embodiment is installed, the air-conditioning main unit back panel surface 1011 is arranged close to the outer facade of the equipment platform, and the back-facing air inlet surface 1012 (main air inlet surface) is arranged towards the inner wall.

[0135] When the air-conditioning and air-energy water heater main unit fusion body of this embodiment is in operation, the ambient atmosphere passes through the facades on both sides and the top of the air-conditioning and air-energy water heater main unit fusion body, flows into the louvers at low speed and low resistance and enters the top and two side spaces of the equipment platform, and then flows through the air-conditioning main unit and the air-energy water heater main unit external heat exchanger through the back-facing air inlet surface 1012 and the air inlet surfaces on both sides and the air inlet surface on the evaporator shell 401, and enters the negative pressure cavity after exchanging heat, and is sucked in and pressurized by the corresponding fan and passes through the exhaust cavity to be injected into the ambient atmosphere at high speed for diffusion and dilution.

[0136] This embodiment innovates the structural layout of the air inlet area and the exhaust area on the facade of the equipment platform, reorganizes the air path structure of the external heat exchanger of the main unit of the air-conditioning air-energy water heater, develops the air supply and distribution duct functions of the idle space on the top of the equipment platform and the inner maintenance space, and reduces the risk of air flow short circuit caused by the main unit fusion body to the external exhaust return flow external heat exchanger.

[0137] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the scope of protection of the present invention.
