Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of air conditioner main machine, and particularly relates to an air conditioner water heater main machine fusion body with an evaporator cavity arranged on top of an air conditioner exhaust cavity. BACKGROUND

[0002] Figures 14 to 16 The advent of the double-carbon era greatly accelerates the popularization of air energy water heaters. Now, household central air conditioner main machines and air energy water heaters have become standard configurations on the equipment platform of high-end housing.

[0003] Now, the air flow structure of the outer heat exchanger cavity of the air conditioner main machine is a paradigm of "large-area low-speed air inlet on the side and back + front multi-fan medium-speed air outlet + air flow side inlet and side outlet" facing the open atmospheric environment.

[0004] In the double-carbon era, household central air conditioner main machines and air energy water heaters, which have become standard configurations on the equipment platform of high-end housing, have the following urgent problems to be solved:

[0005] ① The classic structure of the present household air conditioner main machine has the problems of poor air exhaust and air conditioner performance degradation

[0006] The present household air conditioner main machine excludes high-power multi-split air outlet structure scheme and continues the classic structure of room air conditioner side air outlet, and has serious problems of poor air exhaust and air conditioner performance degradation on the equipment platform: in recent years, building designers have strengthened the decoration of the outer facade of buildings and equipment platforms; when building designers hide air conditioner main machines with shutters on the equipment platform for the visual effect of the outer facade of the building, the medium-speed air exhaust (7 m / s or less) of the air conditioner main machine is hindered by the air exhaust to the atmospheric environment outside the building, the diffusion and dilution effect of the air exhaust is inhibited, and a considerable part of the air exhaust of the outer heat exchanger is blocked by the shutter and returned to the equipment platform and then sucked into the outer heat exchanger, causing air flow short circuit, resulting in excessive condensation pressure and insufficient subcooling of the condensate during summer cooling operation of the air conditioner, and excessively low evaporation pressure and significant reduction of refrigerant circulation during winter heating operation, so that the air conditioner cannot complete the task of heat carrier, and the performance of the air conditioner main machine on the equipment platform is significantly reduced compared with the laboratory data.

[0007] ② The heating energy efficiency ratio of the air energy water heater is reduced, especially in the low-temperature season

[0008] The air energy water heater, which has mature technology but has not started in the market for a long time, has finally accelerated its popularization due to the advent of the double-carbon era. However, in the real high-end housing project, the installation position of the air energy water heater main machine and the water tank on the equipment platform is arbitrary, and it is basically impossible to solve the problem of air exhaust of the heat absorbing evaporator of the water heater main machine.

[0009] However, the heat of an air source water heater comes from the air, and the heat released by the condenser of an air source water heater is mainly the heat absorbed by the evaporator from the air. The evaporator of the main unit of the water heater cannot effectively ventilate to the ambient atmosphere, causing the air outlet of the evaporator to circulate and short-circuit within the small space of the equipment platform, resulting in a continuous drop in the temperature of the small space of the equipment platform, which in turn further reduces the evaporator evaporation pressure and severely reduces the heating capacity.

[0010] This phenomenon is more severe during cold seasons, when the heat pump unit of the water heater degenerates into a single electric heating element.

[0011] ③ The area of ​​inefficient and ineffective equipment platforms increases.

[0012] The standard configuration of residential central air conditioning units and air source water heaters (including the main unit and water tank) is often found to be sparsely distributed on residential equipment platforms. This is because the equipment is dispersed, and air intake channels need to be reserved for the external heat exchanger of the air conditioning unit located at the rear, as well as air intake and exhaust channels need to be reserved for the evaporator of the air source water heater. As a result, the equipment on the platform is sparse, and the ineffective and inefficient area increases. Summary of the Invention

[0054] The present application has the following advantages and positive effects compared with the prior art due to the adoption of the above technical scheme:

[0055] I. Air conditioner main machine air energy water heater evaporator module is combined, structure is complementary, air path is smooth, external facade exhaust port density is reduced, exhaust backflow risk is reduced, and heat exchanger performance is improved

[0056] The current 8HP below household air conditioner main machine continues the classic structure of the room air conditioner side air outlet, and when running on the equipment platform with the decorative louver external facade, the problem of serious exhaust unsmoothness and air conditioner performance degradation occurs: the medium-speed exhaust (7m / s below) of the air conditioner main machine to the atmospheric environment outside the equipment platform itself has very low dynamic pressure head, when the building designer hides the air conditioner main machine with louver on the equipment platform for the visual effect of the building facade, the air conditioner main machine exhaust static pressure is increased due to the louver obstruction, the exhaust speed and exhaust volume are further reduced, and a considerable part of the exhaust airflow is blocked by the louver and then sucked back to the air conditioner main machine back side outer heat exchanger to cause airflow short circuit, so that the air conditioner main machine has high condensation pressure in summer and insufficient subcooling of condensate, low evaporation pressure in winter and large attenuation of refrigerant circulation amount, and the air conditioner as a heat carrier cannot complete the task, so the performance of the air conditioner main machine on the equipment platform is greatly reduced compared with the laboratory data.

[0057] The inner cavity of the outer heat exchanger cavity of the air conditioner host is defined as the negative pressure cavity of the outer heat exchanger of the air conditioner host in an embodiment of the present application, and the concept of the negative pressure cavity is introduced into the structure of the household air conditioner host and the structure of the air energy water heater evaporator module. The structures such as the compressor of the air conditioner host and the compressor of the air energy water heater are arranged in the negative pressure cavity of the outer heat exchanger of the air conditioner host, the structural functions other than the function of the air flow channel in the negative pressure cavity of the outer heat exchanger of the air conditioner host are maximally developed, and all the components outside the negative pressure cavity are removed. The air exhaust cavity of the outer heat exchanger of the air conditioner host is arranged on the top surface of the outer heat exchanger cavity of the air conditioner host, and the air energy water heater evaporator module is arranged above the air exhaust cavity of the outer heat exchanger of the air conditioner host. The air exhaust port of the air energy water heater evaporator module is arranged adjacent to and on the same side of the air exhaust port of the air exhaust cavity of the outer heat exchanger of the air conditioner host, so as to realize the combination of the air conditioner and the water heater host structure, the internal concentration, the external simplicity, and the high-efficiency large device.

[0058] The outer heat exchanger of the air conditioner host and the air energy water heater evaporator cavity of the present embodiment introduce the fresh air flow into the equipment platform outer facade through the front surface and the side surface of the air conditioner host shell and the evaporator shell, the fresh air flow flows through the gap between the fin of the outer heat exchanger at a low speed and low resistance, and then is sucked by the fan, accelerated and pressurized, and discharged into the environment atmosphere in the form of high-speed jet flow at about 10 m / s, and then diffused and diluted.

[0059] The present embodiment is aimed at the problem that the air energy water heater evaporator module air exhaust port is arranged on the facade of the equipment platform, the air inlet surface is fragmented, and the air exhaust is easy to flow back. The air exhaust port of the air energy water heater evaporator module is arranged adjacent to and on the same side of the air exhaust port of the air exhaust cavity of the outer heat exchanger of the air conditioner host, to form an air exhaust port combination facing the environment atmosphere outside the facade of the equipment platform. The air exhaust port of the air energy water heater evaporator module is arranged in a concentrated manner, the density of the air exhaust port on the facade of the equipment platform is reduced, the risk of air exhaust backflow is reduced, and the heat exchange performance of the air conditioner and the water heater host heat exchanger is improved.

[0060] The air conditioner host air energy water heater evaporator module of the present embodiment not only combines the air conditioner and the water heater host, has a simple structure, and has a smooth air path, but also reduces the risk of air exhaust backflow on the facade, improves the refrigeration and heating performance of the host, and approaches the laboratory test data.

[0061] II. Compressing the low-efficiency and ineffective space to save the platform area

[0062] As a two-line city real estate underground parking prices have exceeded the vehicle itself, commercial residential equipment platform prices have long exceeded the platform on the air conditioner, water heater and other equipment itself; The invalid and inefficient area of the air conditioner evaporator module outside the heat exchanger inlet and outlet channel, installation and maintenance space reserved on the equipment platform generates an economic burden on the owner, which is a technical problem, but also an economic problem.

[0063] The present embodiment is directed to the decentralized arrangement of household central air conditioner host and air energy water heater which has become a standard configuration on the equipment platform, and the problem of increasing invalid and inefficient area on the platform caused by reserving the air conditioner host air energy water heater evaporator module outside the heat exchanger inlet and outlet channel; By embedding the fluorine components of the air conditioner host and the air energy water heater host into the negative pressure cavity of the air conditioner host outside the heat exchanger, and embedding the air energy water heater evaporator module into the air conditioner host, a fusion body of the air energy water heater evaporator module embedded in the air conditioner host is constructed, the module unit is embedded and combined again to construct a more efficient secondary fusion system, and the air conditioner host air energy water heater evaporator module outside the heat exchanger is unified as back and two side inlets, which inhale the ambient fresh air from the two sides and the top of the platform exterior, greatly saving the equipment platform area, while opening up the air conditioner host air energy water heater evaporator module outside the heat exchanger air path and improving the refrigeration and heating performance, the economic burden of the developer and the owner is reduced.

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

[0101] Each side of the air conditioner main unit housing 101 includes an air conditioner back panel and at least one air inlet side. The air conditioner main unit external heat exchanger 102 is located inside the air conditioner main unit housing 101 and, together with the aforementioned air inlet side, forms the aforementioned negative pressure chamber of the air conditioner main unit external heat exchanger 102, which connects to the heat exchange air path of the air conditioner main unit external heat exchanger 102. The refrigerant piping of the air conditioner main unit external heat exchanger 102 is used to connect the air conditioner main unit compressor 7 with the refrigerant piping of the air conditioner's internal heat exchanger, forming at least one air conditioner main unit refrigerant circulation loop.

[0102] In this embodiment, the exhaust cavity 2 of the external heat exchanger of the air conditioning unit can be a guide pipe, and the exhaust port of the guide pipe is set facing the exterior of the equipment room.

[0103] Specifically, the sides of the air conditioning unit housing 101 other than the back panel can be configured as the air inlet side of the air conditioning unit housing 101, and the external heat exchanger 102 of the air conditioning unit can be a corresponding C-shaped finned tube external heat exchanger, L-shaped finned tube external heat exchanger, or flat plate finned tube evaporator.

[0104] In this embodiment, the air conditioner's 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. It only needs to meet the requirement of being a power source for airflow, and no specific limitation is made here.

[0105] In this embodiment, the air conditioning unit also includes a four-way valve 9, an expansion valve 10, and an electrical box. The four-way valve 9 and the expansion valve 10 are located on the air conditioning refrigerant circulation loop and within the negative pressure chamber of the external heat exchanger, making full use of the ventilation blind spot within the negative pressure chamber and eliminating all components outside the negative pressure chamber. The electrical box is located on the top surface of the air conditioning unit housing 101, opposite the exhaust port of the external heat exchanger exhaust chamber 2. That is, the electrical box and the external heat exchanger exhaust chamber 2 are arranged side-by-side on the top surface of the air conditioning unit housing 101, with the electrical box located on the back side of the external heat exchanger exhaust chamber 2. Relays, controllers, and other components of both the air conditioning unit and the air source water heater evaporator module are housed within this electrical box.

[0106] In the present embodiment, the air energy water heater evaporator fan 6 can be a centrifugal fan.

[0107] The air energy water heater evaporator exhaust cavity 5 and the surface opposite to the top surface of the centrifugal fan are the fan opposite surface. The first preset interval is left between the fan opposite surface and the centrifugal fan to form the homogenization one-way exhaust cavity air static pressure exhaust passage between the centrifugal fan and the fan opposite surface. The static pressure of the closed side (between the centrifugal fan and each side plate of the air energy water heater evaporator exhaust cavity 55) is reduced, the total cross-sectional area of the one-way exhaust cavity exhaust is expanded, thereby promoting the homogenization of the air static pressure field of the open side (exhaust port side) and the closed side of the one-way exhaust cavity, improving the fan-shaped area exhaust air volume of the closed side of the impeller, and reducing the shaft power of the fan.

[0108] Further, each surface of the air energy water heater evaporator exhaust cavity 5 opposite to the air outlet direction of the centrifugal fan is a side plate. The second preset interval is left between the centrifugal fan and each side plate to form a side plate side exhaust passage between the centrifugal fan and the corresponding side plate, which has the same effect as the first preset interval.

[0109] Referring to Figure 7 , the operation mode of the air conditioner water heater main body fusion body of the present embodiment, in which the evaporator cavity is arranged on top of the air conditioner exhaust cavity, will be further described below:

[0110] When the air conditioner main body operates, the air conditioner main body compressor 7 drives the flow and phase change heat absorption and release of the refrigerant in the air conditioner main body refrigerant circulation loop in the air conditioner main body outer heat exchanger negative pressure cavity; coupled with the phase change heat exchange of the fluorine in the refrigerant, the air conditioner main body outer heat exchanger fan 3 pushes the airflow through the fin gap of the air conditioner main body outer heat exchanger 102 to implement the heat exchange between the ambient air and the refrigerant inside the pipeline of the air conditioner main body outer heat exchanger 102; the air conditioner main body outer heat exchanger fan 3 starts to operate and discharges the airflow to the environment through the upper air guide elbow, while generating negative pressure inside the air conditioner main body outer heat exchanger negative pressure cavity before the air inlet of the air conditioner main body outer heat exchanger fan 3; this negative pressure pulls the ambient air to flow through the fin gap of the air conditioner main body outer heat exchanger 102 and exchanges heat with the refrigerant in the metal tube covered by the metal fin and the metal fin on both sides of the gap, so that the ambient air absorbs heat, rises in temperature and carries away heat in summer to ensure that the high-temperature and high-pressure refrigerant gas in the metal tube continuously condenses and releases heat, and the ambient air lowers the temperature and releases heat in winter to ensure that the low-pressure refrigerant liquid in the metal tube continuously absorbs heat and evaporates.

[0111] When the air energy water heater evaporator module of the embodiment is running, the air energy water heater compressor 8 implanted in the negative pressure cavity of the air conditioner main unit drives the flow and phase change heat absorption and release of the refrigerant in the air energy water heater refrigerant circulation loop; coupled with the phase change heat exchange of the refrigerant in the air energy water heater refrigerant circulation loop, the air energy water heater evaporator fan 6 in the air energy water heater evaporator cavity 4 is started to run, and the air energy water heater evaporator exhaust cavity 5 is used to exhaust air to the environment outside the equipment platform, so as to create a negative pressure state in the air energy water heater evaporator negative pressure cavity, pull the environmental air to flow through the fin gap of the air energy water heater evaporator 402 to reduce the temperature, filter out water vapor and release heat, so as to continuously supply heat to ensure the continuous evaporation of the low-pressure refrigerant liquid in the air energy water heater refrigerant circulation loop and the continuous condensation heat release of the high-temperature and high-pressure refrigerant gas in the water tank after being pressurized by the air energy water heater compressor 88; the air after the heat release of the air energy water heater evaporator 402 is sucked by the air energy water heater evaporator negative pressure cavity and the air energy water heater evaporator fan 6 after the negative pressure cavity, and is pressurized and accelerated to be injected into the environmental air through the air energy water heater evaporator exhaust cavity 5 to be diluted.

[0112] In the embodiment, the air conditioner main unit outer heat exchanger 102 and the air energy water heater evaporator 402 have dense fins on the pipeline, and the fin spacing is very small, usually only 1-2 mm, and the fin gap becomes the main resistance on the outer heat exchanger and the evaporator air duct; inside the air conditioner main unit outer heat exchanger negative pressure cavity and the air energy water heater evaporator negative pressure cavity, the air pressure is relatively balanced and relatively low due to the operation of the fan, and a significant pressure difference is established between the air pressure outside the finned tube heat exchanger and the environment; the pressure difference is the power for the air conditioner main unit outer heat exchanger 102 and the air energy water heater evaporator 402 to ventilate and exchange heat, so as to overcome the resistance to air flow caused by the fin gap.

[0113] Embodiment two

[0114] Referring to Figure 8 and Figure 9 , the embodiment further improves the arrangement mode of the air energy water heater evaporator module on the basis of the above-mentioned embodiment one, and the difference points from the embodiment one are as follows:

[0115] In the embodiment, the air energy water heater evaporator cavity 4 is installed on the top surface of the air conditioner main unit outer heat exchanger exhaust cavity 2.

[0116] The air exhaust device is installed on the side of the air energy water heater evaporator cavity 4 facing the air outlet of the air conditioner main unit outer heat exchanger exhaust cavity 2, that is, the air energy water heater evaporator cavity 4 and the air exhaust device are arranged in parallel on the top surface of the air conditioner main unit outer heat exchanger exhaust cavity 2, and the air outlet of the air exhaust device is arranged in parallel with the air outlet of the air conditioner main unit outer heat exchanger exhaust cavity 2, for extracting air in the air energy water heater evaporator negative pressure cavity and exhausting air in parallel with the air exhaust direction of the air conditioner main unit outer heat exchanger exhaust cavity 2.

[0117] The air exhaust device can include an air energy water heater evaporator exhaust cavity 5 and at least one air energy water heater evaporator fan 6. 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 air outlet of the air conditioner main unit outer heat exchanger exhaust cavity 2. The air outlet of the air energy water heater evaporator exhaust cavity 5 is arranged in parallel with the air outlet of the air conditioner main unit outer heat exchanger exhaust cavity 2.

[0118] The air energy water heater evaporator fan 6 is also installed on the air outlet of the air energy water heater evaporator negative pressure 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 air flow.

[0119] In other embodiments, the air exhaust device can also be at least one axial flow fan. The axial flow fan is installed on the side of the air energy water heater evaporator cavity 4 facing the air outlet of the air conditioner main unit outer heat exchanger exhaust cavity 2, and the air exhaust direction of the axial flow fan is parallel to the air exhaust direction of the air conditioner main unit outer heat exchanger exhaust cavity 2, so as to realize the same direction air exhaust with the air conditioner main unit outer heat exchanger exhaust cavity 2 and form an air outlet combination.

[0120] In this embodiment, the air energy water heater evaporator cavity 4 can specifically include an evaporator shell 401 and an air energy water heater 402. The evaporator shell 401 is arranged on the top surface of the air conditioner main unit outer heat exchanger exhaust cavity 2 and forms the above-mentioned air energy water heater negative pressure cavity together with at least part of the evaporator shell 401, which communicates with the heat exchange air path of the air energy water heater 402. The refrigerant pipeline of the air energy water heater 402 is used to connect the air energy water heater compressor 8 and the inner heat exchanger refrigerant pipeline of the air energy water heater water tank to form at least one air energy water heater refrigerant circulation loop.

[0121] Embodiment three

[0122] Referring to Figure 10 , on the basis of the above-mentioned embodiment one or embodiment two, the air energy water heater evaporator cavity 4 is arranged on the top of the air conditioner air energy water heater main unit fusion body, and the fusion body of the present embodiment can further include an intermediate heat exchanger 13.

[0123] The intermediate heat exchanger 13 is arranged in the negative pressure cavity of the air conditioner main unit outer heat exchanger, and two heat exchange medium channels of the intermediate heat exchanger 13 are respectively connected with the air conditioner refrigerant circulation loop and the air conditioner water circulation loop of the indoor air conditioner unit (which can be an indoor fan coil, and the refrigerant medium therein can be water or other medium). The air conditioner main unit produces cold and hot water through the intermediate heat exchanger 13 to input the fan coil installed in the indoor space to meet the refrigeration and heating demand in the building. In summer, the air conditioner main unit produces cold water through the intermediate heat exchanger 13 to input the indoor fan coil to absorb the heat in the indoor space to realize refrigeration; in winter, the air conditioner main unit produces hot water through the intermediate heat exchanger 13 to input the indoor fan coil to heat the indoor space air to realize heating.

[0124] In the present embodiment, the intermediate heat exchanger 13 can be a plate heat exchanger, a double-pipe heat exchanger or a shell-and-tube heat exchanger, which is not limited herein.

[0125] Since the intermediate heat exchanger 13 is arranged in the air conditioner water heater main unit to output the air conditioning cold and hot water to the indoor fan coil to realize summer refrigeration and winter heating, the air conditioner refrigerant pipeline is limited in the air conditioner water heater main unit, the length is greatly shortened, and the refrigerant leakage risk is greatly reduced; since the air conditioner refrigerant pipeline is limited in the air conditioner water heater main unit on the outdoor equipment platform and does not enter the indoor space, the refrigerant indoor leakage and explosion risk is eliminated, which provides a realistic possibility for the application and promotion of flammable refrigerants such as R290 and R32.

[0126] Embodiment four

[0127] Referring to Figures 11 to 13 , for the air conditioner air energy water heater main unit fusion body in the above-mentioned embodiments one or two, the main unit fusion body still has the problem that the exhaust air of the main unit fusion body may be partially short-circuited by the air conditioner outer heat exchanger arranged below the exhaust air outlet combination of the main unit fusion body. In the present embodiment, the side surface of the air conditioner main unit shell 101 opposite to the air conditioner main unit back plate surface 1011 is set as a back-to-air inlet surface 1012, which faces the inner side of the equipment room (the air conditioner back plate surface 1011 and the back-to-air inlet surface 1012 are both short side corresponding side surfaces of the air conditioner main unit shell 101); and the air conditioner main unit back plate surface 1011 faces the outer side of the equipment room and is located on the same side as the exhaust air outlet (i.e. the exhaust air outlet combination) of the air conditioner main unit outer heat exchanger exhaust air cavity 2.

[0128] Further, the air conditioner main unit outer heat exchanger exhaust air cavity 2 is a wind guide elbow pipe, the flow channel of the wind guide elbow pipe extends upwards and towards the air conditioner back plate surface, and the exhaust air surface of the wind guide elbow pipe is parallel to the air conditioner main unit back plate surface 1011, i.e. is located on the opposite side of the back-to-air inlet surface 1012 to realize back-to-air inlet and forward exhaust.

[0129] Specifically, the back of the air conditioner main shell 101 to the air inlet surface 1012 and one side or two sides connected to it are the air inlet surfaces of the air conditioner main shell 101, and the air conditioner main external heat exchanger 102 can be a corresponding C-shaped finned tube external heat exchanger.

[0130] The air conditioner air energy water heater main body fusion body of the embodiment is installed with the air conditioner main back plate surface 1011 close to the equipment platform outer facade, and the back to the air inlet surface 1012 (main air inlet surface) facing the inner wall.

[0131] When the air conditioner air energy water heater main body fusion body of the embodiment is running, the ambient atmosphere passes through the outer facade on both sides and the top of the air conditioner air energy water heater main body fusion body, flows into the equipment platform top and both sides space through the louver at low speed and low resistance, and then flows through the air conditioner main body, the air energy water heater main body external heat exchanger through the air inlet surface on the back to the air inlet surface 1012 and both sides and the evaporator shell 401, enters the negative pressure chamber after exchanging heat, and is sucked into the booster by the corresponding fan and is shot into the ambient atmosphere at high speed to diffuse and dilute.

[0132] The embodiment innovates the structure and layout of the air inlet area and the air outlet area on the equipment platform outer facade, reorganizes the air path structure of the air conditioner air energy water heater main body fusion body external heat exchanger, develops the air supply and air distribution duct function of the idle space on the equipment platform top and the inside maintenance space, and reduces the risk of airflow short circuit of the main body fusion body to the external exhaust backflow external heat exchanger.

[0133] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above embodiments. Even if various changes are made to the application, if the changes fall within the scope of the claims of the application and equivalent technologies, they still fall within the protection scope of the application.
