Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of high-efficiency energy-saving air conditioning, and more particularly relates to a fan low-positioned air conditioner main unit air energy water heater main unit fusion body and an equipment platform thereof. BACKGROUND

[0002] Now, household central air conditioner main units and air energy water heaters have become standard configurations on equipment platforms of high-end houses. The air path structure of the outer heat exchanger module of the air conditioner main unit is a paradigm of "large-area low-speed air inlet on the side and back + multi-fan medium-speed air outlet on the front + air path side inlet and side outlet" facing an open atmospheric environment.

[0003] The household central air conditioner main units and air energy water heaters that have become standard configurations on equipment platforms of high-end houses have the following problems:

[0004] ① Device resource duplication

[0005] The air conditioner main unit and the air energy water heater main unit are both vapor compression refrigeration devices, and not only have the same working principle, but also have very similar mechanical and electrical structures, that is, a fluorine path system composed of a compressor, a condenser, a throttling valve and an evaporator driven by a compressor, and a high-temperature heat source medium system and a low-temperature heat source medium system driven by a fan and a water pump.

[0006] In a small equipment platform space, such configuration of two sets of physically independent air conditioner main unit devices and heat pump water heating devices with the same principle and similar structure is a duplication of refrigeration device resources and a waste of refrigeration device resources.

[0007] ② Increase of invalid and inefficient area of equipment platform

[0008] Household central air conditioner main units and air energy water heaters (including main units and water tanks) have become standard configurations on residential equipment platforms.

[0009] On the residential equipment platform, air conditioner main units, air energy water heaters and other devices need to be arranged dispersedly as independent units, and an air inlet channel is also reserved for the outer heat exchanger arranged on the rear side of the air conditioner main unit with a rear-in front-out and side-in side-out air path structure, and air inlet and outlet channels are reserved for the evaporator of the air energy water heater main unit, resulting in an increase in the distance between the central air conditioner main unit, the air energy water heater main unit and the water tank and other devices on the equipment platform and an increase in the invalid and inefficient area.

[0010] ③ Decrease of heating energy efficiency of air conditioner heat pumps and air energy water heaters, more so in low-temperature seasons

[0011] Air energy water heater, which has been mature in technology but delayed in market, has greatly accelerated its popularization speed. However, in the real project of refined housing, the installation position of air energy water heater host and water tank on the equipment platform is random, basically, it is inserted into the gap, and it is powerless to solve the problem of heat absorption evaporator of water heater host to the environment ventilation.

[0012] In recent years, building designers have strengthened the decoration of the outer surface of buildings and equipment platforms. When building designers hide air conditioner host and air energy water heater host on the equipment platform with louvers for the visual effect of the outer surface of the building, the exhaust air of medium-speed exhaust (7m / s and below) air conditioner host and air energy water heater host is hindered, the diffusion and dilution effect of the exhaust air penetrating through the louver of the outer surface into the environment is inhibited, and a considerable part of the exhaust air of the outer heat exchanger is blocked by the louver and returned to the equipment platform and then sucked into the evaporator, causing air flow short circuit. When the air conditioner host and air energy water heater host operate in heating mode, the evaporating pressure is too low, the refrigerant circulation is greatly reduced, and the performance of the air conditioner host and air energy water heater host on the equipment platform is greatly reduced compared with the laboratory data.

[0013] In cold winter season, the complex heat pump system of the air conditioner host and air energy water heater host degenerates into an electric heating pipe. SUMMARY

[0048] Compared with the prior art, the present application has the following beneficial effects:

[0049] The air conditioner main machine air energy water heater main machine fusion body with low-positioned fan has the following advantages:

[0050] ①Simple structure and smooth air path

[0051] The air conditioner main machine air energy water heater main machine fusion body has the following advantages: simple structure, smooth air path, reduced density of air outlet of the outer facade of the equipment platform, reduced risk of air exhaust backflow, and improved performance of the heat exchanger.

[0052] The current 8HP or less household air conditioner host continues the classic structure of low-speed air inlet and medium-speed air outlet of room air conditioner, and when running on the equipment platform with the decorative louver outer facade, the problem of poor air exhaust and performance degradation of the air conditioner occurs: the medium-speed air exhaust (7m / s or less) of the air conditioner host to the atmospheric environment outside the equipment platform has a very low dynamic pressure head, when the building designer hides the air conditioner host with louvers on the equipment platform for the visual effect of the building outer facade, the static pressure of the air exhaust of the air conditioner host is increased due to the obstruction of the louver, the exhaust speed and the exhaust amount are further reduced, and a considerable part of the exhaust airflow is blocked by the louver and then sucked back to the outer heat exchanger on the back side of the air conditioner host, causing airflow short circuit, resulting in excessive condensation pressure of the air conditioner host in summer, insufficient supercooling of the condensate, and low evaporation pressure of the air conditioner host in winter, which greatly reduces the refrigerant circulation amount, and the air conditioner as a heat carrier cannot complete the task, and the performance of the air conditioner host on the equipment platform is greatly reduced compared with the laboratory data.

[0053] The two-in-one outer heat exchanger module of the air conditioner host and the air energy water heater host introduces the fresh air flow from the outer facade of the equipment platform, and the fresh air flow flows through the gap between the fins of the two-in-one outer heat exchanger at a low speed and low resistance, and then is sucked into the pressure booster by the fan and is discharged in a diving angle parallel to or close to the louver blade of the outer facade; the exhaust air flow penetrates the louver and other decorations at a low resistance and is discharged into the environment air for diffusion and dilution, and the ability of the exhaust air flow to penetrate the louver and other decorations is greatly enhanced.

[0054] The present application is aimed at the problem of multiple exhaust outlets of the air conditioner host and the air energy water heater host, fragmented air inlet surface, and easy backflow of the exhaust air penetrating the outer facade, the exhaust outlets of the air conditioner host and the air energy water heater host are combined, the density of the exhaust outlets on the outer facade of the equipment platform is reduced, the risk of backflow of the exhaust air is reduced, and the heat exchange performance of the heat exchanger of the air conditioner and the water heater host is improved, which approaches the laboratory test data.

[0055] ②Improve the EER and COP of the air conditioner and water heater refrigeration (heat pump) system

[0056] When the air conditioner host and the air energy water heater host are operated synchronously, the evaporator of the water heater host can also absorb the high-temperature heat release of the condenser of the air conditioner host through the fin heat bridge effect to obtain super-high evaporation pressure and high energy efficiency of the water heater heat pump.

[0057] This invention combines the air conditioning unit and the air source water heater unit into one, resulting in a simple structure, smooth airflow, and reduced risk of exhaust backflow on the exterior facade. Furthermore, when the air conditioning unit and the air source water heater unit are running independently, the heat exchange function of the external heat exchanger fins of the non-operating unit is utilized by the transverse fin thermal bridge effect, thereby improving the utilization coefficient of the entire two-in-one finned tube heat exchanger. This achieves an increase in the heat exchange fin area of ​​the external heat exchanger of the operating unit, a reduction in the heat exchange temperature difference of the heat exchanger body, and an improvement in the energy efficiency ratio of the main unit system.

[0109] The air conditioner main machine air energy water heater main machine fusion body of the embodiment is low in the fan, and in the copper pipe fin resource distribution of the two-in-one outer heat exchanger thereof, the air conditioner main machine accounts for a large proportion, for example, about 2 / 3, and the air energy water heater accounts for a small proportion, for example, about 1 / 3.

[0110] The two-in-one outer heat exchanger module of the embodiment is combined into a horizontal section C type integrated three-surface structure by three flat plate type three-row finned tube heat exchangers, and the horizontal section C type finned tube heat exchanger is ventilated on three surfaces; the middle row structure of the three-row finned tube of the horizontal section C type finned tube heat exchanger belongs to the outer heat exchanger of the air energy water heater main machine; the inner layer (row) and outer layer (row) structures of the three-row finned tube of the horizontal section C type finned tube heat exchanger are shared by the air conditioner main machine, and the air conditioner main machine outer heat exchanger and the air energy water heater evaporator structure are complementary, and the air paths are combined through the fin transverse thermal bridge effect.

[0111] The air conditioner main machine air energy water heater main machine fusion body of the embodiment is low in the fan, and the horizontal section C type outer heat exchanger is continuously transversely and longitudinally in the inner, middle and outer three layers (rows) of fins, the air energy water heater main machine evaporator in the middle layer and the inner and outer layer air conditioner main machine finned tube outer heat exchangers are in heat conduction connection through the fin transverse thermal bridge, the effective use of the fin heat exchange area of the running outer heat exchanger to the stopped outer heat exchanger is realized, so that the fin heat exchange area of the running outer heat exchanger is expanded, the outer heat exchanger body heat transfer temperature difference is reduced, and the system energy efficiency ratio of the running main machine is improved.

[0112] The air conditioner main machine air energy water heater main machine fusion body of the embodiment is low in the fan, and the horizontal section C type outer heat exchanger is continuously transversely and longitudinally in the inner, middle and outer three layers (rows) of fins, the air energy water heater main machine evaporator in the middle layer and the inner and outer layer air conditioner main machine finned tube outer heat exchangers are in heat conduction connection through the fin transverse thermal bridge, the effective use of the fin heat exchange area of the running outer heat exchanger to the stopped outer heat exchanger is realized, so that the fin heat exchange area of the running outer heat exchanger is expanded, the outer heat exchanger body heat transfer temperature difference is reduced, and the system energy efficiency ratio of the running main machine is improved.

[0113] In addition to the wind path merging, the embodiment also adopts a structure complementary design, sets the fluorine path components such as the compressor 121, the four-way valve, and the throttle valve in the rear lower vent blind area of the exhaust cavity and adjacent to the back panel, sets the electrical box 138 in the front vent blind area of the outer heat exchanger negative pressure cavity 124 and adjacent to the front panel, and realizes the internal wind path structure of the outer heat exchanger-outer heat exchanger negative pressure cavity-fan-exhaust cavity-air outlet and the structure complementation of the compressor cavity 332 and the electrical box 138.

[0114] The air conditioner main unit and air energy water heater main unit fusion body with the low-positioned fan of the embodiment adopts the low-speed air inlet and high-speed air outlet mode of the outer heat exchanger 2, and the fan 38 generates negative pressure in the outer heat exchanger negative pressure cavity 124 to suck the air outlet of the outer heat exchanger 2, and the air outlet of the outer heat exchanger 2 is sucked into the booster from the side below the main unit fusion body and injected into the ambient atmosphere environment for diffusion and dilution.

[0115] The structure and principle of the two sets of fluorine path systems of the air conditioner main unit and the air energy water heater main unit of the embodiment are shown in the figure. The air conditioner main unit and air energy water heater main unit fusion body with the low-positioned fan of the embodiment includes two sets of systems, and the fluorine paths of the two sets of systems are open-loop systems. The fluorine path system of the air conditioner main unit is in communication with the fluorine path of the air conditioner indoor unit 131 to form a closed-loop refrigerant circulation system of the air conditioner. The fluorine path system of the air energy water heater main unit is in communication with the condenser 71 in the water tank 7 to form a closed-loop refrigerant circulation system of the air energy water heater.

[0116] The air conditioner main unit and air energy water heater main unit fusion body with the low-positioned fan of the embodiment effectively develops the redundancy of the outer heat exchanger and fan of the household central air conditioner main unit, and improves the comprehensive energy efficiency of the air conditioner and water heater combined system.

[0117] Under the low-load condition, the frequency conversion compressor and the frequency conversion fan of the existing household central air conditioner main unit module run 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 conditioner main unit to have low efficiency under the low-load condition. That is, the air conditioner compressor 121 and the fan 38 have low efficiency under the low-load condition due to the redundancy of the capacity.

[0118] From the time ratio, the time ratio of the load rate of the household central air conditioner 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 living room and dining room are also operated at different times.

[0119] The redundancy of the outdoor heat exchanger and the fan capacity of the low load of the current household central air conditioner host provides conditions for the integration of the air energy water heater host evaporator into the air conditioner host outdoor heat exchanger.

[0120] The horizontal section C-shaped finned tube outdoor heat exchanger of the air conditioner host air energy water heater host integration of the embodiment has an intermediate layer and an outer layer structure belonging to the air conditioner host and the water heater host, respectively, and realizes the structural complementation of the air conditioner host outdoor heat exchanger and the air energy water heater evaporator and the merging of the air flow paths through the transverse fin heat bridge.

[0121] The structural complementation of the air conditioner host outdoor heat exchanger and the air energy water heater evaporator and the merging of the air flow paths in the embodiment can exploit the redundancy of the air conditioner host outdoor heat exchanger to improve the heat absorption area and the heat absorption capacity of the water heater evaporator when the air energy water heater is running by using the transverse fin heat bridge effect between the two sets of refrigerant pipelines of the air conditioner host outdoor heat exchanger and the air energy water heater evaporator.

[0122] ①If the air conditioner host is in a refrigeration running state, its outdoor heat exchanger 2 serves as a condenser and directly introduces part of the high-temperature condensation heat of the refrigerant into the water heater evaporator pipeline through the vertical fin heat bridge to improve the refrigerant evaporation temperature and the evaporation pressure of the evaporator.

[0123] ②If the air conditioner host is in a heating running state, its outdoor heat exchanger serves as an evaporator and absorbs heat from the ambient air flow together with the water heater evaporator. If the air conditioner host is in a low load running state during heating, the outdoor heat exchanger has redundant capacity, which can still be utilized by the water heater evaporator through the transverse fin heat bridge to improve the evaporation temperature and the evaporation pressure of the water heater evaporator. If the air conditioner host is in a high load running state during heating, the air energy water heater host and the air conditioner host can be set to staggered operation through the control system. When the control system detects that the air conditioner host stops running, the air energy water heater host starts to heat the cold water in the water tank.

[0124] ③If the air conditioner host is in a stopped running state, the fins on the inner layer and the outer layer of the outdoor heat exchanger close to the discharge pipeline of the water heater evaporator serve as the transverse extension of the evaporator fins, which expands the effective heat absorption area of the evaporator, reduces the heat transfer temperature difference of the evaporator itself under certain heat absorption power and certain environmental temperature and humidity conditions, and improves the refrigerant evaporation temperature and the evaporation pressure of the evaporator.

[0125] The exploitation and utilization of the air conditioner host outdoor heat exchanger capacity by the water heater evaporator through the fin heat bridge effect in the embodiment focuses on the improvement of the evaporation temperature and the evaporation pressure of the water heater evaporator.

[0126] The air conditioner main unit air energy water heater main unit fusion body of the embodiment has the fan set low, and on the basis of complementary structure and combined air path of the air conditioner main unit outer heat exchanger and the air energy water heater evaporator, the redundant capacity of the air conditioner main unit outer heat exchanger is converted into the heat absorption capacity of the air energy water heater main unit evaporator through the vertical fin heat bridge.

[0127] Similarly, on the basis of complementary structure and combined air path of the air conditioner main unit outer heat exchanger and the air energy water heater evaporator, the redundant capacity of the air energy water heater evaporator in the shutdown state is converted into the heat absorption and release capacity of the air conditioner main unit outer heat exchanger through the horizontal fin heat bridge, thereby improving the comprehensive energy efficiency of the air conditioner main unit.

[0128] In the air conditioner main unit air energy water heater main unit fusion body of the embodiment, the air conditioner main unit and the air energy water heater main unit can be operated simultaneously or individually.

[0129] When the air conditioner main unit is operated, the flow and phase change heat absorption of the refrigerant in the air conditioner fluorine path driven by the air conditioner main unit compressor in the negative pressure cavity of the two-in-one outer heat exchanger module outer heat exchanger; coupled with the phase change heat exchange of the refrigerant in the fluorine path, the air flow is pushed by the fan to pass through the gap between the fins of the air conditioner main unit outer heat exchanger, thereby implementing the heat exchange between the ambient air and the refrigerant in the inner pipeline of the outer heat exchanger; the fan discharges air flow to the ambient atmosphere to the side and downward, and at the same time, negative pressure is generated in the negative pressure cavity of the outer heat exchanger before the air inlet of the fan; the negative pressure pulls the ambient air to flow through the gap between the heat-conducting metal fins of the air conditioner main unit outer heat exchanger, and exchanges heat with the refrigerant in the metal pipe wall covered by the fins on both sides of the gap; in summer, the ambient air passes through the fins to increase the temperature, absorb heat and take away heat to ensure that the high-temperature and high-pressure refrigerant gas in the metal pipe continuously releases heat and condenses; in winter, the ambient air passes through the fins to reduce the temperature and release heat to ensure that the low-pressure refrigerant liquid in the metal pipe continuously absorbs heat and evaporates; after heat exchange, the air flowing into the negative pressure cavity of the outer heat exchanger is sucked into the fan to increase the pressure and is injected into the ambient atmosphere to diffuse and dilute.

[0130] The air-to-water heat pump main unit of the embodiment drives the flow and phase change heat absorption of the fluorine route refrigerant of the air-to-water heat pump through the air-to-water heat pump compressor in the negative pressure cavity of the outer heat exchanger; coupled with the phase change heat exchange of the fluorine route refrigerant, the fan of the two-in-one outer heat exchanger module causes a negative pressure state in the negative pressure cavity of the outer heat exchanger, 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 the continuous evaporation of the low-pressure refrigerant liquid in the evaporator pipeline and the continuous condensation heat release of the high-temperature and high-pressure refrigerant gas in the water tank after being pressurized by the compressor; the air entering the negative pressure cavity of the outer heat exchanger after the heat release of the evaporator fin of the air-to-water heat pump main unit is sucked into the negative pressure cavity of the outer heat exchanger by the fan after the outer heat exchanger, and is injected into the ambient atmosphere to the side and downward to diffuse and dilute.

[0131] Embodiment 2

[0132] As shown in Figures 11-12 , the fan low-positioned air conditioner main unit air-to-water heat pump main unit fusion body of the embodiment is similar to that of embodiment 1, and the air conditioner main unit outer heat exchanger and the water heater evaporator air route structure are implemented in a centralized manner, and are combined into a two-in-one outer heat exchanger module air route that has the functions of heat exchange between the air conditioner main unit and the ambient atmosphere and heat absorption between the air-to-water heat pump main unit and the ambient atmosphere.

[0133] The difference between this embodiment and the previous embodiment is that the overall structure of the outer heat exchanger 2 is I-shaped, i.e. a flat plate finned tube outer heat exchanger, and the fins are complete and continuous, and the fin thermal bridge effect is complete and continuous.

[0134] Due to the overall structure of the air conditioner main unit air-to-water heat pump main unit fusion body outer heat exchanger being I-shaped, the outer heat exchanger can be inclinedly arranged in the upper cavity (the outer heat exchanger negative pressure cavity 124) of the main unit fusion body, and the fan 38 can be positioned upwardly close to the outer heat exchanger water collecting tray 132, which is conducive to reducing the height of the main unit fusion body and improving the ventilation and heat exchange uniformity of the two-in-one outer heat exchanger.

[0139] When the main unit fusion body of the equipment platform of the air conditioner main unit air energy water heater main unit fusion body installed with the fan low position is running, the fan is started and runs as the power of the external heat exchanger air path, the air in the external heat exchanger negative pressure chamber is extracted to generate negative pressure in the external heat exchanger negative pressure chamber, the external heat exchanger negative pressure chamber negative pressure draws the air outside the heat exchanger into the external heat exchanger negative pressure chamber to generate a secondary negative pressure zone outside the external heat exchanger; the secondary negative pressure of the external heat exchanger outside the external heat exchanger draws the ambient air to flow through the external shutter at low speed and low resistance, and the ambient air flowing through the shutter into the secondary negative pressure zone flows into the fin gap of the finned tube heat exchanger of the air conditioner main unit at low speed and exchanges heat with the refrigerant inside the tube. After the heat exchange, the airflow is sucked into the fan through the main unit fusion body heat exchanger negative pressure chamber, and after the pressure is raised, it is discharged into the exhaust chamber, and finally the exhaust air outlet of the main unit fusion body is injected into the air outlet section of the air outlet section; the exhaust air flow is constrained and induced by the air outlet section guide plate group parallel or basically parallel to the shutter blade, and finally enters the atmospheric environment to diffuse and dilute.

[0140] The equipment platform of the air conditioner main unit air energy water heater main unit fusion body installed with the fan low position has the following advantages:

[0141] ①Innovative air path structure, promote the fusion of main unit fusion body and equipment platform external facade

[0142] Because of the modernization and fashion of buildings, because of the pursuit of building designers and owners for the visual effect of building facade, because of the whole society's love for "architecture is solidified music", and the function of the shutter to block wind and rain to prevent wind, rain and snow from eroding the equipment platform and air conditioner main unit equipment, the air conditioner main unit installation method of hiding the air conditioner main unit on the equipment platform will be popularized and solidified, and the classic air conditioner main unit "rear-to-front" air path of the external heat exchanger will be hindered and inhibited by the shutter, the exhaust static pressure will be increased, the exhaust air volume will be reduced, and the heat exchange performance of the external heat exchanger will be seriously degraded.

[0143] The embodiment creates conditions for the low-resistance penetration of the external heat exchanger exhaust of the main machine fusion body through the external vertical surface louver of the equipment platform, because the air conditioner main machine air energy water heater main machine fusion body low-position fan and air outlet are adopted in the equipment platform; a diving exhaust section is set between the air outlet of the main machine fusion body and the external vertical surface louver of the equipment platform, forming a low-resistance diving exhaust of the external heat exchanger to the ambient atmosphere, and the flow direction of the exhaust air flow is parallel or close to parallel to the louver blade gap, which not only eliminates the obstruction of the traditional louver blade to the external heat exchanger exhaust of the main machine fusion body, effectively penetrates the external heat exchanger air path, and guarantees the thermal performance of the main machine fusion body, but also maintains the decorative effect of the external vertical surface louver, realizes the perfect unity of the decorative effect of the external vertical surface of the equipment platform, the visual effect of the external vertical surface of the building, and the excellent thermal performance of the main machine fusion body.

[0151] When the embodiment is installed and constructed, the exhaust section 35 installed on the air outlet 331 is inserted into the opening structure 36 on the louver.

[0152] When the main machine fusion body of the equipment platform of the air conditioner main machine air energy water heater main machine fusion body with the low-positioned fan is running, the fan is started to run as the air path power of the outer heat exchanger, the air in the negative pressure cavity of the outer heat exchanger is extracted to generate negative pressure in the negative pressure cavity, the negative pressure in the negative pressure cavity pulls the air outside the outer heat exchanger to flow into the negative pressure cavity of the outer heat exchanger, thereby generating a secondary negative pressure area outside the outer heat exchanger; the secondary negative pressure outside the outer heat exchanger pulls the ambient air to flow through the outer facade louver at a low speed and low resistance, the ambient air flowing through the louver into the secondary negative pressure area flows into the fin gap of the finned tube heat exchanger at a low speed and exchanges heat with the refrigerant inside the tube, and the airflow after exchanging heat passes through the negative pressure cavity of the outer heat exchanger and is sucked by the fan, is pressurized and discharged into the exhaust cavity, and finally is injected into the exhaust section from the exhaust cavity outlet, and finally is directly injected into the atmospheric environment for diffusion and dilution.
