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 complementary wind path merging of an external heat exchanger structure. BACKGROUND

[0002] Reference Figures 19 to 21 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 a well-furnished house.

[0003] Now, the wind path structure of the external 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 path side inlet and side outlet" facing an 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 a well-furnished house, have the following problems:

[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, which excludes the high-power multi-split "upward air outlet" structure scheme and continues the side air outlet classic structure of the room air conditioner, has the serious problems of poor air exhaust and air conditioner performance degradation when installed on the equipment platform: in recent years, building designers have strengthened the decorative nature of the outer facade of the building and the equipment platform; when the building designer hides the air conditioner main machine with a louver to improve the visual effect of the outer facade of the building, the medium-speed air exhaust (below 7 m / s) of the air conditioner main machine is hindered by the outer atmospheric environment, the diffusion and dilution effect of the exhaust air flow of the external heat exchanger is inhibited, the static pressure is increased and the air volume is reduced, and a considerable part of the exhaust air flow of the external heat exchanger is blocked by the louver and returned to the equipment platform and then sucked into the external heat exchanger, causing air flow short circuit, resulting in excessive condensing pressure and insufficient subcooling of the condensing liquid during the refrigeration operation of the air conditioner main machine in summer, and excessively low evaporation pressure and a large decrease in the circulation amount of the refrigerant during the heating operation of the air conditioner main machine in winter, so that the air conditioner, as a heat carrier, cannot complete its task, and the performance of the air conditioner main machine on the equipment platform is greatly 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 been launched in the market for a long time, has finally greatly accelerated its popularization due to the advent of the double-carbon era. However, in the actual well-furnished house project, the installation positions of the air energy water heater main machine and the water tank on the equipment platform are arbitrary, and it is basically impossible to solve the problem of air inlet of the heat absorption evaporator of the water heater main machine.

[0009] However, the heat source of the air energy water heater is air, the heat release of the condenser in the water tank of the air energy water heater, and the heat absorbed by the evaporator from the air; the evaporator of the water heater main machine cannot effectively ventilate the environment, causing the evaporator outlet to circulate in the small space of the equipment platform, resulting in a continuous decrease in the temperature of the small space of the equipment platform, which in turn further reduces the evaporating pressure of the evaporator and seriously reduces the heating capacity.

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

[0011] ③The invalid and inefficient area of the equipment platform increases

[0012] The household central air conditioner main machine and the air energy water heater (including the main machine and the water tank) that have become standard configurations are arranged on the residential equipment platform, and due to the dispersion of the equipment, the air conditioner main machine is arranged at the rear side of the outer heat exchanger, and the air energy water heater main machine evaporator is arranged at the rear side of the outer heat exchanger, which causes the equipment on the platform to be sparse, and the invalid and inefficient area to increase.

[0051] Compared with the prior art, the air conditioner water heater main machine fusion body with the structure of complementary air exchange and merged air path of the present application has the following advantages and positive effects:

[0052] I. Improving the energy efficiency ratio COP of the two sets of refrigeration (heat pump) systems of the air conditioner and the water heater

[0053] In this embodiment, the air conditioning unit and the air source water heater unit are not only integrated into one unit, with a simple structure and smooth airflow, reducing the risk of exhaust air recirculation on the exterior facade and improving the cooling and heating performance of the unit, but also the heat exchangers of the air conditioning unit and the water heater unit are combined. Several external heat exchanger finned plates are arranged side by side, and the refrigerant piping systems of the air conditioning unit and the air source water heater unit are set to alternately pass through each external heat exchanger finned plate group. The refrigerant piping systems of the air conditioning unit and the air source water heater unit occupy part of the fins of each external heat exchanger finned plate group. When the air conditioning unit and the air source water heater unit are running independently, the vertical fin thermal bridge effect utilizes the fin portion of the external heat exchanger finned plate group corresponding to the non-running unit to exchange heat with the ambient air, improving the utilization coefficient of the entire external heat exchanger finned plate group integration, and realizing the expansion of the heat exchange fin area of ​​the external heat exchanger of the running unit and the reduction of the heat exchange temperature difference.

[0054] In this embodiment, when the air conditioner unit is cooling and the air source water heater is heating simultaneously, the evaporator of the water heater unit can also absorb the high-temperature heat released by the air conditioner unit condenser through the thermal bridge effect of the fins to obtain ultra-high evaporation pressure and ultra-high energy efficiency of the water heater heat pump.

[0055] This embodiment not only helps to save resources and improve the utilization coefficient of finned tube heat exchangers, but also helps to increase the evaporation pressure during air conditioning heating and hot water production, and reduce the condensation pressure during air conditioning cooling, thereby improving the COP of the two systems, air conditioning and water heater.

[0056] II. Simple structure and smooth airflow

[0057] Current residential air conditioning units, inheriting the classic side-discharge structure of low-speed air intake and medium-speed air exhaust in room air conditioners, exhibit severe problems of poor airflow and degraded air conditioning performance when operating on equipment platforms with decorative louvers. The air conditioning unit's dynamic head for medium-speed exhaust (below 7m / s) to the external atmosphere is already very low. When architects conceal the air conditioning unit on the equipment platform with louvers for visual appeal, the louvers obstruct the airflow, increasing the static pressure and further reducing the exhaust velocity and volume. A significant portion of the reduced exhaust airflow is also blocked by the louvers and drawn back to the external heat exchanger on the back of the air conditioning unit, causing airflow short-circuiting. This results in excessively high condensing pressure and insufficient condensate cooling in summer, and excessively low evaporating pressure and a significant reduction in refrigerant circulation in winter. Consequently, the air conditioner cannot adequately fulfill its function as a heat transporter, leading to a substantial decrease in the performance of the air conditioning unit on the equipment platform compared to laboratory data.

[0058] This embodiment defines the concept of "negative pressure cavity" and injects the concept of "negative pressure cavity" into the structure of household air conditioner main unit and air energy water heater main unit. The air conditioner compressor, four-way valve, throttling valve and other fluorine components and air energy water heater compressor are arranged in the air conditioner main unit negative pressure cavity to maximize the development of the structure function outside the air flow channel function of the air conditioner air energy water heater main unit negative pressure cavity. All components outside the negative pressure cavity are removed to realize the "combination of two, internal concentration, external simplicity, high efficiency and large device" of the air conditioner and water heater main unit structure.

[0059] This embodiment of the air conditioner water heater main unit fusion body of the structure complementary air path merging of the external heat exchanger introduces fresh air flow from the equipment platform outer facade. The fresh air flow flows through the gap between the fin of the air conditioner air energy water heater main unit fusion body external heat exchanger at a low speed and low resistance to complete heat exchange and then enters the air conditioner air energy water heater main unit negative pressure cavity. After that, the fresh air flow is sucked by the air conditioner air energy water heater main unit fusion body fan, accelerated and boosted, and then discharged into the environment at a speed of about 10 m / s in the form of high-speed jet flow for diffusion and dilution. The dynamic head of the 10 m / s high-speed jet flow in this embodiment is 1.0 times higher than that of the traditional 7 m / s medium-speed jet flow, and the ability to penetrate through decorative obstacles such as louvers is greatly enhanced.

[0060] This embodiment is aimed at the problem of multiple air outlets on the air conditioner main unit and air energy water heater main unit on the outer facade of the existing equipment platform, the fragmentation of the air inlet surface of the outer facade, and the easy backflow of the air outlet through the outer facade. The air outlets of the air conditioner main unit and the air energy water heater main unit are combined into one. The density of the air outlets on the outer facade of the equipment platform is reduced, the risk of air backflow is reduced, and the heat exchange performance of the heat exchanger of the air conditioner and water heater main unit is improved, approaching the laboratory test data.

[0061] Three, resource conservation and energy efficiency improvement

[0062] Under low load conditions, the variable frequency fan runs at a low frequency and low speed, and multiple efficiencies such as motor efficiency and mechanical efficiency decrease, resulting in a significant decrease in the total efficiency of the fan, which is a product of motor efficiency and mechanical efficiency. This causes low efficiency of household central air conditioning main unit under low load conditions due to capacity redundancy. The extremely low efficiency of variable frequency fan and variable frequency compressor under low load rate has been a problem in the refrigeration and air conditioning industry.

[0063] This embodiment is aimed at the problem of low load of the external heat exchanger fan of the household central air conditioning main unit. Based on the structure complementarity and air path merging of the air conditioner main unit external heat exchanger and the air energy water heater evaporator, the redundancy of the variable frequency fan of the household central air conditioning main unit external heat exchanger is developed. The redundancy of the variable frequency fan of the central air conditioning main unit is converted into the power of the air energy water heater main unit evaporator air path to replace the dedicated fan of the water heater evaporator, saving the air duct and fan components of the air energy water heater main unit, and improving the overall energy efficiency of the air conditioner and water heater combined system.

Detailed Implementation

[0089] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a fusion of an air conditioning and water heater unit with complementary external heat exchanger structures and combined airflow paths, as proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims.

[0090] See Figures 1 to 7 and Figure 10 In one embodiment, an air conditioning water heater main unit fusion body with complementary external heat exchanger structure and combined airflow path includes an air conditioning air source water heater main unit fusion body housing 1, an external heat exchanger of the air conditioning air source water heater main unit fusion body, an air conditioning compressor 4, an air source water heater compressor 5, and at least one air conditioning air source water heater main unit fusion body fan 3.

[0091] The air conditioner air energy water heater main body fusion external heat exchanger is arranged in the air conditioner air energy water heater main body fusion shell 1, and forms an air conditioner air energy water heater main body negative pressure cavity with at least part of the air conditioner air energy water heater main body fusion shell 1, which communicates with the air conditioner air energy water heater main body external heat exchanger heat exchange air path. The air conditioner air energy water heater main body fusion external heat exchanger includes at least one external heat exchanger fin plate group fusion body 2. The external heat exchanger fin plate group fusion body 2 includes an air conditioner main body refrigerant pipeline system 205, an air energy water heater main body refrigerant pipeline system 206, and at least two external heat exchanger fin plate groups 201 arranged side by side from inside to outside. The air conditioner main body refrigerant pipeline system 205 and the air energy water heater main body refrigerant pipeline system 206 are alternately arranged in each external heat exchanger fin plate group 201.

[0092] The air conditioner compressor 4 is arranged in the air conditioner air energy water heater main body negative pressure cavity, and is used to connect the air conditioner main body refrigerant pipeline system 205 and the air conditioner internal heat exchanger refrigerant pipeline 10 to form at least one set of air conditioner refrigerant circulation loop, and serves as the air conditioner system refrigerant circulation power. The air energy water heater compressor 5 is arranged in the air conditioner air energy water heater main body negative pressure cavity, and is used to connect the air energy water heater main body refrigerant pipeline system 206 and the air energy water heater water tank 13 internal heat exchanger refrigerant pipeline 10 to form at least one set of air energy water heater refrigerant circulation loop, and serves as the air energy water heater refrigerant circulation power.

[0093] The air conditioner air energy water heater main body fusion fan 3 is installed on the top surface of the air conditioner air energy water heater fusion shell and communicates with the air conditioner air energy water heater main body negative pressure cavity, and is used to generate negative pressure in the air conditioner air energy water heater main body negative pressure cavity to absorb the air conditioner air energy water heater main body external heat exchanger outflow, and to accelerate the air conditioner air energy water heater main body external heat exchanger outflow to shoot upward into the environment atmosphere.

[0094] The air conditioner main machine air energy water heater main machine of the embodiment not only combines two into one, has simple structure, smooth air path, and reduces the risk of external facade exhaust backflow and improves the refrigeration and heating performance of the main machine. The air conditioner main machine heat exchanger and the water heater main machine heat exchanger are combined, a plurality of external heat exchanger fin plate groups 201 are arranged, and the air conditioner main machine refrigerant pipeline system 205 and the air energy water heater main machine refrigerant pipeline system 206 are arranged to be alternately arranged in each external heat exchanger fin plate group 201. The air conditioner main machine refrigerant pipeline system 205 and the air energy water heater main machine refrigerant pipeline system 206 occupy part of the fins of each external heat exchanger fin plate group 201. When the air conditioner main machine and the air energy water heater main machine are operated independently, the vertical fin heat bridge effect is used to stop the operation of the corresponding external heat exchanger fin plate group 201 of the main machine, and the fin part of the external heat exchanger fin plate group 201 is used to exchange heat with the environment. The utilization coefficient of the whole external heat exchanger fin plate group 2 is improved, the heat exchange fin area of the operating main machine external heat exchanger is expanded, and the heat exchange temperature difference is reduced.

[0095] When the air conditioner main machine refrigeration and the air energy water heater heating are operated synchronously, the water heater main machine evaporator can also absorb the high-temperature heat release of the air conditioner main machine condenser 12 through the fin heat bridge effect to obtain super-high evaporation pressure and high-efficiency water heater heat pump. Not only is it beneficial to save resources and improve the utilization coefficient of the finned tube heat exchanger, but also it is beneficial to improve the evaporation pressure during air conditioning heating and hot water production and reduce the condensation pressure during air conditioning refrigeration, thereby improving the energy efficiency ratio COP of the air conditioner and the water heater system.

[0096] The specific structure of the air conditioner water heater main machine fusion body of the embodiment will be further described below.

[0097] Referring to Figure 3 and Figure 4 In the embodiment, the number of external heat exchanger fin plate groups 201 can be two. Each external heat exchanger fin plate group 201 is arranged with a plurality of U-shaped refrigerant pipe groups in the vertical direction, and each U-shaped refrigerant pipe group includes a plurality of U-shaped refrigerant pipes arranged in the vertical direction.

[0098] The U-shaped refrigerant pipes in the two U-shaped refrigerant pipe groups arranged side by side in the two external heat exchanger fin plate groups are connected by a plurality of staggered communication bends 203 to form air conditioner refrigerant branches and air energy water heater branches that are alternately arranged;

[0099] Each air conditioner refrigerant branch in the two external heat exchanger fin plate groups is arranged in parallel to form the air conditioner main machine refrigerant pipeline system described above. Similarly, each air energy water heater branch is arranged in parallel to form the air energy water heater main machine refrigerant pipeline system described above.

[0100] For the convenience of understanding, the above-mentioned outer heat exchanger fin plate group fusion body 2 is further explained: first, since the C-shaped or L-shaped outer heat exchanger is bent from a long strip-shaped flat plate-shaped fin tube outer heat exchanger, and if two rows of vertical refrigerant pipelines are arranged in a single flat plate-shaped fin tube outer heat exchanger, the bending radius of the inner and outer refrigerant pipelines will be different, which will cause the bending to be impossible.

[0101] Therefore, in the embodiment, the outer heat exchanger fin plate group fusion body 2 is arranged as a combination of multiple outer heat exchanger fin plate groups 201, U-shaped refrigerant pipelines, and communication bends.

[0102] First, the concept of the outer heat exchanger fin plate group 201 is explained: only one row of insertion holes is arranged in the outer heat exchanger fin plate group 201, which is used for inserting the vertically arranged U-shaped refrigerant pipelines. Taking the number of U-shaped refrigerant pipelines in each row as an example, if the number is 20, based on the refrigerant flow resistance, 5 U-shaped refrigerant pipelines can be arranged as a group (a total of four groups). The first side of the 5 U-shaped refrigerant pipelines is provided with a bend, and the other side can form a branch through 4 communication bends. That is, the uppermost U-shaped refrigerant pipeline and the lowermost U-shaped refrigerant pipeline flow out of one pipe opening respectively, which are used as the refrigerant inlet (gas / liquid inlet) and the refrigerant outlet (gas / liquid outlet). That is, the 20 U-shaped refrigerant pipelines can form four branches, and the gas pipelines and the liquid pipelines of the four branches are connected in parallel and then connected to the corresponding compressor, four-way valve, and other components.

[0103] In the embodiment, based on the design concept of combining the air conditioner outer heat exchanger with the air energy water heater evaporator, in order to realize the function of heat transfer between the air conditioner main machine and the air energy water heater main machine when they are running independently, through the vertical fin heat bridge, the arrangement form of the communication bend 203 is further changed in the embodiment. The communication bend 203 is changed from connecting the vertically adjacent U-shaped refrigerant pipelines in the same outer heat exchanger fin plate group 201 to connecting the U-shaped refrigerant pipelines on the two outer heat exchanger fin plate groups 201 arranged side by side, so that the above-mentioned branch is formed in the fins of the two outer heat exchanger fin plate groups 201. In addition, the communication bends 203 are staggered, that is, the upper and lower two U-shaped refrigerant pipelines (a total of four) arranged side by side in the horizontal direction. The upper left corner U-shaped refrigerant pipeline and the lower right corner U-shaped refrigerant pipeline are connected by one communication bend 203, and the lower left corner U-shaped refrigerant pipeline and the upper right corner U-shaped refrigerant pipeline are connected by one communication bend 203, which is similar to the form of being wound with each other, forming two refrigerant flow paths, thereby realizing the function of heat transfer between the two through the vertical fin heat bridge.

[0104] That is, the communication bends are X-shaped and cross and communicate with corresponding U-shaped refrigerant pipes, although the fins between the two outer heat exchanger fin plate groups 201 are transversely disconnected, but through the left-right staggered arrangement, the upper-lower staggered arrangement of the U-shaped air conditioner main refrigerant pipe system 205 and the U-shaped air energy water heater main refrigerant pipe system 206, and the vertical fins in the outer heat exchanger fin plate group 201 establish a thermal bridge connection, realize the effective utilization of the fin heat exchange area of the running main machine outer heat exchanger to the stopped main machine outer heat exchanger, thereby reducing the heat transfer temperature difference of the running main machine outer heat exchanger and improving the system energy efficiency ratio, realizing the structure complementation of the air conditioner main machine outer heat exchanger and the air energy water heater evaporator, and the wind path merging.

[0105] Further, based on the consideration of the power of the air conditioner main machine and the power of the air energy water heater, the air conditioner and air energy water heater main machine fusion body outer heat exchanger can further include a separate outer heat exchanger fin plate group 202, that is, a total of three outer heat exchanger fin plate groups 201, arranged side by side on the outside or inside of the outer heat exchanger fin plate group fusion body 2. The independent outer heat exchanger fin plate group 202 is provided with an independent air conditioner main machine refrigerant pipe system 204, which is connected in parallel to the air conditioner main machine refrigerant pipe system 205, so that the air conditioner main machine can occupy about two-thirds of the fin resources to meet the refrigerating capacity demand of the air conditioner main machine.

[0106] In the present embodiment, the outer heat exchanger fin plate group fusion body 2 is a C-shaped finned tube heat exchanger or an L-shaped finned tube heat exchanger, which can also be a single-row flat plate type finned tube heat exchanger bent into an L-shaped or C-shaped fin transverse disconnection and vertical continuous superposition.

[0107] Referring to Figure 2 and Figure 6 In the present embodiment, at least one side of the air conditioner and air energy water heater main machine fusion body shell 1 is the back plate surface 101, and the area inside the air conditioner and air energy water heater main machine negative pressure cavity close to the back plate surface 101 and the bottom plate of the air conditioner and air energy water heater main machine fusion body shell 1 is a ventilation blind area. The air conditioner compressor 4 and the air energy water heater compressor 5 are arranged in the ventilation blind area.

[0108] Among them, the arrangement track of the air conditioner compressor 4 and the air energy water heater compressor 5 is arranged in descending order along the direction away from the back plate surface 101, or the arrangement track of the air conditioner compressor 4 and the air energy water heater compressor 5 is parallel to the back plate surface 101, and is arranged in descending order from the central position close to the back plate surface 101. The air conditioner compressor 4 and the air energy water heater compressor 5 with large power, large weight and large noise are arranged in descending order on the corresponding bottom plate in the ventilation blind area, sharing the negative pressure cavity space resource on the bottom plate, greatly reducing the structural gravity center of the air conditioner and water heater main machine fusion body, and suppressing the structural resonance of the main machine caused by the operation of the compressor, creating the conditions and advantages of the fusion of the air energy water heater main machine and the air conditioner main machine.

[0109] Referring to Figure 7 In the embodiment, the air conditioner water heater main body fusion body with the outer heat exchanger structure and the complementary air path merging can further include an air conditioner main body four-way valve, an air conditioner main body expansion valve, an air energy water heater four-way valve 11, an air energy water heater expansion valve, and an electrical box 6.

[0110] The air conditioner main body four-way valve and the air conditioner main body expansion valve are arranged in the air conditioner air energy water heater main body negative pressure cavity, and the air conditioner main body four-way valve and the air conditioner main body expansion valve are arranged on the air conditioner refrigerant circulating loop. The air energy water heater four-way valve 11 and the air energy water heater expansion valve are arranged in the air conditioner air energy water heater main body negative pressure cavity, and the air energy water heater four-way valve 11 and the air energy water heater expansion valve are arranged on the air energy water heater refrigerant circulating loop. This arrangement makes full use of the ventilation blind area in the air conditioner main body outer heat exchanger negative pressure cavity by the related fluorine path device, and cancels all components outside the negative pressure cavity. The electrical box 6 is arranged on the back plate surface 101, and is located in the air conditioner air energy water heater main body negative pressure cavity. The relays, controllers and other components of the air conditioner main body and the air energy water heater module are arranged in the electrical box 6.

[0111] Referring to Figure 15 The air energy water heater four-way valve 11 arranged can be applied to defrosting of the evaporator (the outer heat exchanger fin plate group fusion body 2) in a low temperature environment. The air energy water heater four-way valve 11 is reversely switched to convert the heat absorbing evaporator into a condenser 12 to implement reverse heat pump defrosting, and further expand the temperature and humidity conditions of the air source water heater use environment.

[0112] Referring to Figure 16 In the embodiment, the air conditioner water heater main body fusion body with the outer heat exchanger structure and the complementary air path merging can further include an air conditioner air energy water heater main body fusion body exhaust cavity 7. The input end of the air conditioner air energy water heater main body fusion body exhaust cavity 7 is connected to the top surface of the air conditioner air energy water heater main body fusion body shell 1, and covers the air conditioner air energy water heater main body fusion body fan 3. The output port of the air conditioner air energy water heater main body fusion body exhaust cavity 7 is connected to the equipment platform outer facade louver.

[0113] That is, an exhaust air guide cover (air conditioner air energy water heater host fusion body exhaust cavity 7) is arranged on the top of the air conditioner water heater host fusion body, the upper air outlet is changed to lateral exhaust air, and the exhaust air flow penetrates the equipment platform outer facade louver to enter the environment atmosphere for diffusion and dilution. In view of the dispersed arrangement of the household central air conditioner host and the air energy water heater host on the equipment platform, and the problems of sparse equipment and increased invalid and inefficient area caused by the reserved air conditioner host air energy water heater host outer heat exchanger air inlet and outlet channels, the exhaust air guide cover is arranged to build a two-in-one host and equipment platform outer facade louver combination, so that the outer heat exchanger of the host directly faces the platform outer facade to inhale the environment fresh air and exhaust the air after heat exchange, greatly compresses the traditional inefficient space such as the outer heat exchanger air inlet duct, and greatly saves the equipment platform area. While opening up the air conditioner host air energy water heater host outer heat exchanger air path and improving the refrigeration and heating performance, the equipment platform area is degraded.

[0114] In the embodiment, the air conditioner host and the air energy water heater host can be simultaneously operated or individually operated.

[0115] Referring to Figure 8 When the air conditioner host is operated, the air conditioner compressor 4 drives the flow and phase change heat absorption and release of the refrigeration medium in the air conditioner air energy water heater host negative pressure cavity air conditioner refrigeration medium pipeline system 205 (air conditioner fluorine path). Coupled with the phase change heat exchange of the refrigeration medium in the air conditioner host refrigeration medium pipeline system 205, the air conditioner air energy water heater host fusion body fan 3 pushes the airflow to penetrate the fin gap of the air conditioner air energy water heater host fusion body outer heat exchanger, to implement the heat exchange between the environment air and the refrigeration medium in the air conditioner host refrigeration medium pipeline system 205; the fan exhausts the airflow to the environment atmosphere upward, and at the same time, the negative pressure is generated in the negative pressure cavity before the fan suction port; the negative pressure pulls the environment air to flow through the gap of the heat conduction metal fin of the air conditioner air energy water heater host fusion body outer heat exchanger, and exchanges heat with the refrigeration medium in the metal pipe wall and the pipe through the fins on both sides of the gap and the metal pipe wall covered by the fins; in summer, the environment air penetrates the fins to increase the temperature, absorb heat and take away heat to ensure that the high-temperature and high-pressure refrigeration medium gas in the metal pipe continuously releases heat and condenses; in winter, the environment air penetrates the fins to reduce the temperature, release heat and leave heat to ensure that the low-pressure refrigeration medium liquid in the metal pipe continuously absorbs heat and evaporates; after heat exchange, the air flowing into the negative pressure cavity is pressurized and accelerated by the fan, and is injected into the environment atmosphere upward for diffusion and dilution.

[0116] Referring to Figure 9, the air conditioner air energy water heater host body fusion body fan 3 in the air conditioner air energy water heater host body negative pressure cavity causes a negative pressure state, pulls the ambient air to flow through the evaporator fin gap to reduce the temperature, filter out water vapor, and release heat, to continuously supply heat to ensure continuous evaporation of low-pressure refrigerant liquid in the air energy water heater fluorine path and continuous condensation and heat release of high-temperature and high-pressure refrigerant gas in the water tank 13 after being compressed in the condenser 12; the air entering the air conditioner air energy water heater host body negative pressure cavity after the air conditioner air energy water heater host body fusion body fin corresponding part heat release is sucked into the air conditioner air energy water heater host body negative pressure cavity by the air conditioner air energy water heater host body fusion body fan 3, and is pressurized and accelerated to be shot upward into the ambient atmosphere to be diluted.

[0117] In this embodiment, the air conditioner air energy water heater host body fusion body outer heat exchanger is combined with the air energy water heater host body evaporator, the fin density on the outer heat exchanger is high, and the fin spacing is very small, usually only 1-2 mm, and the fin gap is the main resistance in the air conditioner outer heat exchanger and the water heater evaporator air path; in the negative pressure inside the air conditioner air energy water heater host body, the air conditioner air energy water heater host body fusion body fan 3 operation causes the air pressure to be relatively balanced and relatively low, and a significant pressure difference is established between the air pressure outside the fin-tube outer heat exchanger and the ambient air pressure; this pressure difference is the driving force for air flow in the air conditioner host body outer heat exchanger and the air energy water heater host body evaporator, which overcomes the resistance to air flow caused by the fin gap.

[0118] The air conditioner water heater host body fusion body of this embodiment adopts a longitudinal fin heat bridge to implement the complementary air path merging of the outer heat exchanger structure, effectively develops the redundancy of the outdoor heat exchanger and fan of the household central air conditioner host, and improves the comprehensive energy efficiency of the air conditioner water heater two-in-one combined system.

[0119] Compared with room split air conditioners, household central air conditioners are widely welcomed in residential decoration because only one air conditioner host device platform is needed, and multiple indoor units are embedded in each room, which is atmospheric and clean, and is even a representative configuration of high-end residences; and variable frequency compressors and variable frequency fans are major breakthroughs in the field of refrigeration technology, which have brought wide load adaptability of refrigeration systems due to the adjustability of discharge volume and refrigeration capacity and external circulation air volume, and can respond to real-time load demand of synchronous operation of 1, 2, 3...n different number of indoor units, and are widely used in variable load household central air conditioning systems.

[0120] However, under low load conditions, the variable frequency compressor and the variable frequency fan of the household central air conditioning main unit operate at low frequency and low speed, and the motor efficiency, mechanical efficiency and other efficiencies decrease, resulting in a significant decrease in the total efficiency of the compressor and the total efficiency of the fan, which are the product of the motor efficiency and the mechanical efficiency, and causing the household central air conditioning main unit to have low efficiency under low load conditions. That is, the air conditioner compressor 4 and the outdoor heat exchanger fan have low efficiency under low load conditions due to redundant capacity.

[0121] In terms of time ratio, the time ratio of the load rate of the household central air conditioning main unit at 50% and above is very low, and the time ratio of the load rate below 30% is high. This is because the bedrooms in a family residence are usually not fully occupied, and only the rooms where people sleep will have the air conditioner indoor unit running at night, and the air conditioner indoor units in the rooms where people live and the public spaces such as the dining room are also operated at different times.

[0122] The redundancy of the outdoor heat exchanger and the fan capacity of the household central air conditioning main unit under low load provides conditions for the integration of the air energy water heater evaporator air path into the air conditioner main unit outdoor heat exchanger air path.

[0123] In the scheme of three outer heat exchanger fin plate groups 201 adopted in this embodiment, the outer heat exchanger fin plate groups 201 of the middle layer and the outer layer are shared by the air conditioner main unit and the water heater main unit, and the refrigerant pipelines (fluorine copper pipes) of the air conditioner main unit outdoor heat exchanger and the air energy water heater evaporator are arranged in a left-right staggered manner and an up-down staggered manner in the outer heat exchanger fin plate groups 201 of the middle layer and the outer layer, realizing the structural complementation of the air conditioner main unit outdoor heat exchanger and the air energy water heater evaporator and the merging of the air paths.

[0124] This embodiment realizes the structural complementation of the air conditioner main unit outdoor heat exchanger and the air energy water heater evaporator and the merging of the air paths, and when the air energy water heater is running, it utilizes the vertical fin "thermal bridge" effect between the two sets of refrigerant pipelines of the air conditioner main unit outdoor heat exchanger and the water heater evaporator to explore the redundant capacity of the household central air conditioning main unit outdoor heat exchanger to improve the heat absorption area and heat absorption capacity of the water heater evaporator:

[0125] ① If the air conditioner main unit is in a refrigeration running state, the air conditioner air energy water heater main unit fusion body outdoor heat exchanger acts as a condenser 12, and directly introduces part of the high-temperature condensation heat of the refrigerant into the water heater evaporator pipeline through the vertical fin thermal bridge, thereby increasing the refrigerant evaporation temperature and evaporation pressure of the evaporator.

[0126] If the air conditioner host is in a heating operation state, the outer heat exchanger of the air conditioner air energy water heater host fusion body acts as an evaporator, and the water heater evaporator jointly absorbs heat from the ambient air flow; if the air conditioner host is in a low load operation state during heating, the redundant capacity of the outer heat exchanger can still be utilized by the water heater evaporator through the vertical fin heat bridge to increase the evaporation temperature and evaporation pressure of the water heater evaporator.

[0127] If the air conditioner host is in a spring and autumn season stop operation state, the fins on the fin plate group 201 of the outer heat exchanger of the middle layer and the outer layer near the water heater evaporator pipeline act as vertical extensions of the evaporator fins, expanding the effective heat absorption area of the evaporator, and under certain heat absorption power and certain environmental temperature and humidity conditions, the evaporator's own heat transfer temperature difference is reduced, and the evaporator's refrigerant evaporation temperature and evaporation pressure are increased.

[0128] The water heater evaporator of the present embodiment utilizes the redundant capacity of the air conditioner host outer heat exchanger through the fin heat bridge effect, and the technical effect is concentrated in the increase of the evaporation temperature and evaporation pressure of the water heater evaporator.

[0129] Among them, the evaporation pressure is the first factor of the heat pump system, which affects the performance of the heat pump system as follows Figure 11 As shown in the figure (the vertical coordinate is the condensation pressure, and the horizontal coordinate is the enthalpy value, and in the figure, 1-2-3-4 is the original cycle path, and 1-2-3 ， -4 ， is the present cycle path):

[0130] (1) The increase of evaporation pressure (P1→P1 ， ) directly leads to the increase of the heat absorption amount of unit mass of refrigerant of the air energy water heater (h4 ， -h4), the reduction of the compressor compression work (h4 ， -h4), and the improvement of the energy efficiency ratio;

[0131] (2) The increase of evaporation pressure (P1→P1 ， ) also directly leads to the increase of the refrigerant circulation amount of the fixed frequency heat pump system by about (P1 ， / P1-1) × 100%, and the increase of the condenser heating power by about (P1 ， / P1-1) × 100%;

[0132] (3) The increase of evaporation pressure also directly leads to the reduction of compression ratio and the reduction of compressor discharge temperature, effectively inhibiting the deterioration of lubricating oil and the degradation of compressor motor insulation performance.

[0133] The embodiment is based on the complementary structure and combined air path of the outdoor heat exchanger of the air conditioner host and the evaporator of the air energy water heater. The redundant capacity of the outdoor heat exchanger of the household central air conditioner host and the variable frequency fan is explored. The part of the heat exchange redundant capacity of the outdoor heat exchanger of the central air conditioner host is converted into the heat absorption capacity of the evaporator of the air source water heater through the vertical fin heat bridge. The part of the redundant capacity of the fan 3 (the variable frequency fan of the outdoor heat exchanger of the central air conditioner host) of the air conditioner air energy water heater host is converted into the power of the air energy water heater host evaporator air path to replace the special fan of the water heater evaporator. The fan component resource is saved, and the energy efficiency of the air energy water heater host is improved.

[0134] Similarly, the embodiment is based on the complementary structure and combined air path of the outdoor heat exchanger of the air conditioner host and the evaporator of the air energy water heater. The redundant capacity of the air energy water heater evaporator in the shutdown state is also explored. The heat exchange redundant capacity of the water heater evaporator is converted into the heat absorption and release capacity of the outdoor heat exchanger of the central air conditioner host through the vertical fin heat bridge. The comprehensive energy efficiency of the air conditioner host is improved.

[0135] Embodiment two

[0136] Reference Figure 12 and Figure 13 Based on the above embodiment one, the embodiment provides an air conditioner water heater host fusion body with complementary structure and combined air path of the outdoor heat exchanger. The structure of the outdoor heat exchanger of the air conditioner air energy water heater host fusion body is adjusted as follows.

[0137] The number of the outdoor heat exchanger fin plate group 201 can be three, which are the first outdoor heat exchanger fin plate group 209, the second outdoor heat exchanger fin plate group 208 and the third outdoor heat exchanger fin plate group 207.

[0138] The first outdoor heat exchanger fin plate group 209 is arranged with a plurality of U-shaped refrigerant pipe groups along the vertical direction. Each U-shaped refrigerant pipe group includes a plurality of U-shaped refrigerant pipes arranged along the vertical direction. The U-shaped refrigerant pipes in each U-shaped refrigerant pipe group form an independent air conditioner refrigerant branch through a plurality of communication elbows.

[0139] The second outdoor heat exchanger fin plate group 208 and the third outdoor heat exchanger fin plate group 207 are also arranged with a plurality of U-shaped refrigerant pipe groups along the vertical direction. Each U-shaped refrigerant pipe group includes a plurality of U-shaped refrigerant pipes arranged along the vertical direction.

[0140] In the second outdoor heat exchanger fin plate group 208 and the third outdoor heat exchanger fin plate group 207, the U-shaped refrigerant pipes in the two parallel U-shaped refrigerant pipe groups are connected through a plurality of staggered communication elbows to form alternating air conditioner refrigerant fusion branches and air energy water heater fusion branches.

[0141] Wherein, the air conditioner refrigerant independent branch in parallel and the air conditioner refrigerant fusion branch are connected in series to form the air conditioner refrigerant series branch, and each air conditioner refrigerant series branch is connected in parallel to form the air conditioner main refrigerant pipeline system 205. Each air energy water heater fusion branch is connected in parallel to form the air energy water heater main refrigerant pipeline system 206.

[0142] Further, the first outer heat exchanger fin plate group 209 can be divided into an upper layer and a lower layer, the U-shaped refrigerant pipe group in the upper layer and the communication elbow form the upper layer air conditioner refrigerant independent branch 210, and the U-shaped refrigerant pipe group in the lower layer and the communication elbow form the lower layer air conditioner refrigerant independent branch 211. The second outer heat exchanger fin plate group 208 and the third outer heat exchanger fin plate group 207 can also be divided into an upper layer and a lower layer, the U-shaped refrigerant pipe group in the upper layer and the communication elbow form the upper layer air conditioner refrigerant independent branch 212, and the U-shaped refrigerant pipe group in the lower layer and the communication elbow form the lower layer air conditioner refrigerant independent branch 213.

[0143] The corresponding upper layer air conditioner refrigerant independent branch 210 in the horizontal direction can be connected with the upper layer air conditioner refrigerant fusion branch 212 in parallel to form the upper layer refrigerant branch 214, and the corresponding lower layer air conditioner refrigerant independent branch 211 can be connected with the lower layer air conditioner refrigerant fusion branch 213 in parallel to form the lower layer refrigerant branch 215. Each upper layer refrigerant branch 214 and each lower layer refrigerant branch 215 are connected in parallel to form the air conditioner main refrigerant pipeline system 205.

[0144] The difference between the embodiment and the above-mentioned embodiment one is that the air conditioner main outer heat exchanger occupies the air conditioner air energy water heater main fusion body outer heat exchanger 2 / 3 copper pipe fin resources. Under the condition of keeping the total amount of copper pipe fin resources unchanged, the copper pipe fin resources are reorganized. The inner side branch of the outer heat exchanger fin plate group 201 in the embodiment one is disassembled into two sections, the middle and outer side branch is disassembled into two sections, and the disassembled inner side branch upper section and the middle and outer side branch upper section are reorganized into one branch, and the inner side branch lower section and the middle and outer side branch lower section are reorganized into another branch.

[0145] The embodiment has all advantages of embodiment one, and because the upper section of the inner side branch and the upper section of the middle outer side branch in the outer heat exchanger fin plate group fusion body 2 are recombined into one branch, and the lower section of the inner side branch and the lower section of the middle outer side branch are recombined into another branch, the copper pipe fin resource occupancy of the two recombined branches does not change, but the new two branches have the ability to seize the same copper pipe fin heat exchange area of the air source water heater evaporator through the fin heat bridge effect, and both operate countercurrently with the ventilation airflow, so that the heat exchange capacity of the two new branches of the air conditioner outer heat exchanger is more symmetrical and balanced.

[0146] Embodiment three

[0147] Referring to Figure 14 , the embodiment is based on the above-mentioned embodiment one, and provides an air conditioner water heater main machine fusion body with outer heat exchanger structure complementary air path merging. The structure of the air conditioner air energy water heater main machine fusion body outer heat exchanger is adjusted, and the specific adjustment is as follows:

[0148] The number of the outer heat exchanger fin plate group 201 can be two. Each outer heat exchanger fin plate group 201 is vertically arranged with a plurality of refrigerant pipe groups, and each U-shaped refrigerant pipe group includes a plurality of U-shaped refrigerant pipes and air energy water heater refrigerant pipes arranged alternately in sequence in the vertical direction (the arrangement mode from top to bottom is one U-shaped refrigerant pipe, one air energy water heater refrigerant pipe, one U-shaped refrigerant pipe...).

[0149] Among them, the U-shaped refrigerant pipes in the two U-shaped refrigerant pipe groups in the two outer heat exchanger fin plate groups are connected by a plurality of communication elbows to form an air conditioner refrigerant branch 216. The air energy water heater refrigerant pipes in the two U-shaped refrigerant pipe groups in the two outer heat exchanger fin plate groups are connected by a plurality of communication elbows to form an air energy water heater branch.

[0150] Each air conditioner refrigerant branch in the two outer heat exchanger fin plate groups can be connected in parallel to form an air conditioner main machine refrigerant pipe system 205. Similarly, each air energy water heater branch can be connected in parallel to form an air energy water heater main machine refrigerant pipe system 206. (Reflecting to the combination of the two outer heat exchanger fin plate groups 201, one set of air energy water heater main machine refrigerant pipe system 206 is arranged between every two sets of air conditioner main machine refrigerant pipe system 205, realizing that the air conditioner main machine outer heat exchanger occupies two-thirds of the fin resources, and the water heater evaporator occupies one-third of the fin resources)

[0151] The embodiment has all the advantages of embodiment one, and because the structure of the two rows of outer heat exchanger fin plate groups 201 is adopted instead of the three rows of pipe structure in embodiments one / two, the air conditioning air energy water heater main body fusion body outer heat exchanger has larger ventilation area, lower ventilation speed and smaller ventilation resistance; in the scene of independent operation of the air conditioner or independent operation of the air energy water heater, all fin resources of the fusion body are used, and the utilization rate of the fins is higher; the C-shaped and L-shaped outer heat exchanger modules reassembled from the flat finned tube heat exchanger are universal.

[0152] Embodiment four

[0153] Referring to Figure 17 , on the basis of the above-mentioned embodiments one, embodiment two, embodiment three, the application provides an air conditioner water heater main body fusion body with complementary wind path merging of outer heat exchanger structure, which is as follows:

[0154] The air conditioner water heater main body fusion body can further include a floor type air conditioner air energy water heater main body fusion body exhaust cavity 8. The floor type air conditioner air energy water heater main body fusion body exhaust cavity 8 includes an upper end air inlet channel, a vertical air duct and a lower end air outlet channel which are sequentially connected, and the output port of the lower end air outlet channel is connected to the equipment platform outer facade louver. The upper end air inlet channel, the vertical air duct and the lower end air outlet channel jointly form an installation space. The air conditioner air energy water heater main body fusion body shell 1 is installed in the installation space, and the top surface of the air conditioner air energy water heater main body fusion body shell 1 is connected to the input port of the upper end air inlet channel.

[0155] That is, the air deflector is arranged on the side surface and the bottom of the air conditioner air energy water heater main body fusion body shell 1, and the air deflector cooperates with the equipment platform outer facade louver to build an outer heat exchanger wind path with short path and low resistance.

[0156] The embodiment has all the advantages of embodiments one, two and three, and because the air deflector and the low-position strip-shaped air outlet are additionally arranged on the side surface and the bottom of the main body, the outer heat exchanger wind path with short path and low resistance is built in cooperation with the equipment platform outer facade louver, and the low-efficiency and invalid space is compressed, and the platform area is saved.

[0157] The air conditioner air energy water heater main body fusion body outer heat exchanger of the embodiment no longer takes air from the back, but takes air from the front side, directly inhaling ambient fresh air from the platform outer facade louver, which greatly saves the equipment platform area, opens the air conditioner air energy water heater main body fusion body outer heat exchanger wind path, improves the refrigeration and heating performance, reduces the construction engineering quantity, and reduces the economic burden of the developer and the owner; and the low-position strip-shaped air outlet of the embodiment is easier to dock, install and maintain with the outer facade louver, and more effectively prevents the fragmentation of the outer facade air inlet surface and the air outlet backflow short circuit.

[0158] Embodiment five

[0159] Referring to Figure 18 , the air conditioner water heater main body fusion body of the embodiment is further improved on the basis of the air conditioner water heater main body fusion body of the above-mentioned embodiment one or embodiment two or embodiment three, and the air conditioner water heater main body fusion body of the embodiment can further include an intermediate heat exchanger 15.

[0160] The intermediate heat exchanger 15 is arranged in the air conditioner air energy water heater main body negative pressure cavity, and two heat exchange medium channels of the intermediate heat exchanger 15 are respectively communicated with an air conditioner main body refrigerant circulating loop and an internal heat exchanger refrigerant pipeline 10 of a building internal air conditioner indoor unit, and the internal heat exchanger refrigerant pipeline 10 can be an air conditioner water circulating loop (which can be an indoor fan coil, and the refrigerant therein can be water or other medium). The air conditioner main body produces cold and hot water through the intermediate heat exchanger 15 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 body produces cold water through the intermediate heat exchanger 15 to input the indoor fan coil to absorb the heat in the indoor space to realize refrigeration; in winter, the air conditioner main body produces hot water through the intermediate heat exchanger 15 to input the indoor fan coil to heat the indoor space air to realize heating.

[0161] Among them, the intermediate heat exchanger 15 can be a plate heat exchanger, a double-pipe heat exchanger, or a shell-and-tube heat exchanger, which is not specifically limited here.

[0162] Because the intermediate heat exchanger 15 is arranged in the air conditioner water heater main body to output the air conditioner cold and hot water to the indoor fan coil to realize summer refrigeration and winter heating, the air conditioner main body refrigerant pipeline system 205 is limited in the air conditioner water heater main body, the length is greatly shortened, and the refrigerant leakage risk is greatly reduced; because the air conditioner main body refrigerant pipeline system 205 is limited in the air conditioner water heater main body on the outdoor equipment platform, it no longer enters the indoor space, the refrigerant indoor leakage and explosion risk is eliminated, and the practical possibility is provided for the application and promotion of the flammable refrigerant such as R290 and R32.

[0163] Embodiment six

[0164] Referring to Figures 19 to 21 , for the problem that when the air conditioner air energy water heater main body fusion body of the above-mentioned embodiment one runs, the main body fusion body still has the problem that the exhaust air of the main body fusion body can be partially short-circuited by the air conditioner external heat exchanger below the exhaust air outlet of the main body fusion body, the side surface opposite to the back plate surface 101 of the air conditioner air energy water heater main body fusion body shell 1 is set as a back-to-air inlet surface 102 in the embodiment; the back-to-air inlet surface 102 faces the inside of the equipment room; and the back plate surface 101 faces the outside of the equipment room, and is located on the same side as the exhaust air outlet of the air conditioner air energy water heater main body fusion body exhaust cavity 7, that is, the back-to-air inlet surface 102 is located on the opposite side to realize back-to-air inlet and forward exhaust.

[0165] Specifically, the back-to-air-inlet face 102 and one side or two sides connected thereto of the air conditioner air energy water heater main body fusion shell 1 are the air-inlet faces of the air conditioner air energy water heater main body fusion shell 1, and the outer heat exchanger fin plate group 201 can be a corresponding C-shaped fin tube outer heat exchanger.

[0166] The air conditioner air energy water heater main body fusion of the embodiment is installed with the back plate face 101 close to the equipment platform outer facade, and the back-to-air-inlet face 102 (main air-inlet face) facing the inner wall.

[0167] When the air conditioner air energy water heater main body fusion of the embodiment is running, the ambient atmosphere passes through the outer facades on both sides and the top of the air conditioner air energy water heater main body fusion, flows into the equipment platform top and both sides space at low speed and low resistance through the louver, and then flows through the outer heat exchanger fin plate group fusion 2 through the back-to-air-inlet face 102 and the air-inlet faces on both sides, enters the negative pressure cavity after heat exchange, is sucked into the booster by the corresponding fan, and is shot into the ambient atmosphere at high speed to diffuse and dilute.

[0168] 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 outer heat exchanger of the air conditioner air energy water heater main body fusion, develops the air supply and air distribution air duct function of the idle space on the equipment platform top and the inside maintenance space, and reduces the risk of airflow short circuit caused by the main body fusion to the outer exhaust backflow outer heat exchanger.

[0169] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above-described 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 thereof, they still fall within the protection scope of the application.
