Description
Technical Field
The invention belongs to the technical field of building design, and particularly relates to a host fusion body and equipment platform of a single-air-duct double-refrigerating system with an air inlet face and an air outlet face arranged in an orthogonal mode.
Background
The air path structure of the external heat exchanger module of the main machine of the household air conditioner is a marked model of 'side-back large-area low-speed air inlet + front multi-fan medium-speed air exhaust air path side-in and side-out' facing the open atmosphere environment.
As shown in fig. 1, the present household air conditioner host machine excludes the scheme of the air outlet structure on the high-power multi-split air conditioner and the classical structure of the air outlet on the side of the continuous room air conditioner, and transfers the air outlet from the open atmospheric environment suspended on the outer facade of a building to the equipment platform with the decorative outer facade, so that serious problems of unsmooth air exhaust and air conditioner performance degradation occur: in recent years, building designers strengthen the decoration of the outer facade of a building and an equipment platform, when the building designers hide an air conditioner host on the outer facade of the equipment platform by using a shutter for the visual effect of the outer facade of the building, the medium-speed exhaust (below 7 m/s) air conditioner host is blocked from exhausting air to the atmosphere outside the building, the static pressure of the exhaust is increased, the exhaust speed is reduced, the air quantity is reduced, a considerable part of air flow in the reduced exhaust air quantity is blocked by the shutter to return to the equipment platform and is again inhaled by an outer heat exchanger to cause air flow short circuit, the diffusion dilution effect of the air exhaust penetrating through the shutter of the outer facade into the environment is severely inhibited, so that the condensation pressure of the outer heat exchanger is insufficient when the air conditioner host is used for refrigerating operation in summer, the evaporation pressure of the outer heat exchanger is excessively low, the refrigerant circulation quantity of the air conditioner is greatly attenuated when the air conditioner is used for heating operation in winter, the task of the air conditioner serving as a heat carrier cannot be completed at a sufficient amount, and the performance of the air conditioner host on the equipment platform is greatly reduced compared with the performance of the air conditioner host on the equipment platform in laboratory data.
At present, an air energy water heater is also arranged on the fine room equipment platform. Although the power of the air-source water heater is generally smaller than that of a household central air conditioner, the requirement of hot water required for home bath, cooking and sanitary washing is continuously increased along with the evolution of life style and sanitary habit, and the household air-source water heater is started and operated frequently even in spring and autumn when the air conditioner is rarely operated.
However, in the current real-life smart dress room project, the installation position of the air energy water heater host computer and the water tank on the equipment platform has randomness, basically meets the seam inserting needle, and is more unlikely to solve the problem of ventilation to the environment of the heat absorption evaporator of the water heater host computer.
The heat of the air energy water heater is derived from air, the heat of the condenser of the air energy water heater is released, and the main body is the heat extracted from the air by the evaporator; the evaporator of the main machine of the water heater cannot effectively ventilate the ambient atmosphere, so that the air outlet of the evaporator is circularly short-circuited in the small space of the equipment platform, the temperature of the small space of the equipment platform is continuously reduced, and the evaporation pressure of the evaporator is further reduced, and the heating quantity is seriously attenuated; the phenomenon of severe cold and low temperature season is more serious, and the heat pump main machine of the water heater is degenerated into an electric heating tube.
The two-carbon era comes, the popularization of the air energy water heater is greatly accelerated, and a household central air conditioner host and the air energy water heater become standard configurations on a fine room equipment platform in the eye; in summary, the classic household central air conditioner host and the air energy water heater in the early stage of the double carbon age have the following problems:
(1) the performance of the air energy water heater of the air conditioning host on the equipment platform is attenuated; the diffusion and dilution effects of the air discharged through the outer elevation shutter and injected into the environment atmosphere are severely inhibited, and the thermal performance of the air energy water heater of the air conditioning host on the equipment platform is greatly reduced compared with laboratory data.
(2) Repeatedly configuring equipment resources; in a narrow equipment platform space, two sets of air-conditioning water heaters which are mutually independent in physical principle and similar in structure are integrated with a host machine and heat pump water heating equipment, so that the air-conditioning water heater is the repeated allocation of refrigeration equipment resources.
(3) The ineffective and inefficient area of the equipment platform is increased; as the equipment such as the host fusion body and the air energy water heater on the residential equipment platform are required to be distributed as independent units, the distance between the central host fusion body, the air energy water heater host and the water tank on the equipment platform is increased, and the ineffective and inefficient area is increased.

(1) Host fusion structure design innovation
Compared with a classical household main machine fusion body and an air energy water heater main machine, the main machine fusion body with the single air channel and the double refrigeration systems orthogonally arranged on the air inlet surface and the air outlet surface of the embodiment has the characteristics that:
a V-shaped finned tube heat exchanger assembly with an oversized heat exchange area and a horizontal section is adopted; the refrigerant pipelines of the external heat exchanger correspond to two sets of independent refrigeration systems, and the two sets of refrigerant pipelines are thermally connected through the longitudinal and transverse heat bridges of the flat-plate finned tube fins.

The V-shaped finned tube heat exchanger assembly with the horizontal section consists of at least 2 flat plate type finned tube heat exchangers; the section of the horizontal section V-shaped finned tube heat exchanger assembly perpendicular to the long sides of the fins is a folded line type; the refrigerant pipelines of two sets of refrigeration systems in the flat-type finned tube heat exchanger are used for evaluating the heat exchange area of the fins of the opposite side through the longitudinal and transverse heat bridges of the fin plate group.
In the limited space of the main engine fusion body of the single air duct double refrigeration system, which is orthogonally arranged on the air inlet surface and the air outlet surface, the horizontal section V-shaped finned tube heat exchanger assembly is arranged in parallel with the air inlet surface direction of the air inlet 11, the air inlet surface of the horizontal section V-shaped finned tube heat exchanger assembly is unfolded to obtain a large-area ventilating surface of the external heat exchanger, and the large-area ventilating surface of the external heat exchanger is unfolded again to obtain a large-area heat transfer surface of the fins, so that the total heat transfer area S of the fins of the main engine fusion body external heat exchanger is effectively enlarged, the heat transfer temperature difference t of the external heat exchanger body is reduced, the evaporating pressure is increased, the condensing pressure is reduced, and the refrigerating capacity Q and the energy efficiency ratio COP of the refrigeration and air conditioning system are improved.
The negative pressure cavity 22 of the external heat exchanger is formed by combining a bottom plate (namely the bottom plate of the shell 1), a side plate, a back plate, the external heat exchanger and a top plate (namely the top plate of the shell 1);
the back plate 21 is arranged opposite to the outer heat exchanger 2 transversely, an air outlet 23 of a negative pressure cavity 22 of the outer heat exchanger is arranged on the back plate 21, and the air outlet 23 is provided with an air suction inlet of a backward inclined outer rotor centrifugal fan; the air suction inlet of the backward-inclined outer rotor centrifugal fan faces to the outer heat exchanger 2. The heat exchanger arranged transversely is an air inlet of the negative pressure cavity of the outer heat exchanger. An exhaust cavity 3 of the centrifugal fan is arranged outside the back plate 21 of the negative pressure cavity 22 of the outer heat exchanger.
The compressor chamber 4 is arranged on the outer side of the back plate of the exhaust chamber 3, and 2 groups of refrigerant circulation system compressors 41, four-way valves, expansion valves and other fluorine path components, electric boxes and other circuit components of the single-air-channel double-refrigerating-system host fusion body are arranged on the exhaust surface of the air inlet surface in an orthogonal mode.
(2) Innovative structure of air inlet and exhaust airflow path of external heat exchanger
The outer heat exchanger 2 of this embodiment has a progressive layout of the air inlet 11, the outer heat exchanger negative pressure chamber 22, the fan wall, the air exhaust chamber 3 and the air outlet 31, and constructs an outer heat exchanger air inlet and outlet path with short path, low resistance, large air volume and high heat exchange strength.
When the outer heat exchanger 2 of the embodiment is in ventilation heat exchange operation, the centrifugal fan is used as power from the air inlet 11 to the air outlet 31, heat exchange air flow undergoes two static pressure-dynamic pressure conversions, the first static pressure-dynamic pressure conversion realizes high-speed air flow suction at the air inlet of the centrifugal fan, and the second static pressure-dynamic pressure conversion realizes high-speed air flow discharge at the air outlet 31 of the air exhaust cavity 3; in addition, the air flow lines entering and exiting the fin gaps of the fin tube heat exchanger are fold line type air flow lines turning twice and are positioned in a plane perpendicular to the long sides of the fins, but not in a plane parallel to the fins; these two points are the most essential movement characteristics of the ventilation and heat exchange process of the outer heat exchanger 2 of the present embodiment.
In the embodiment, the air inlet and outlet fields of the external heat exchanger are established through the operation of 4 centrifugal fans on the fan wall: the centrifugal fan wall is vertically provided with 4 centrifugal fans to pump and exhaust air in the negative pressure cavity 22 of the outer heat exchanger to generate negative pressure in the cavity, the ambient air under the static pressure (gauge pressure) of 0Pa is pulled to enter the main engine from the air inlet of the main engine at a medium speed (about 4 m/s), the air inlet flow of the main engine is shaved by a plurality of fin planing knives to realize the dispersion and deceleration of the air inlet flow, the air flows at a low speed (below 2 m/s) through the fin gaps of the outer heat exchanger to complete heat exchange, then enters the negative pressure cavity 22 of the outer heat exchanger, is collected and accelerated, and flows into the air inlet of the centrifugal fan with the lowest full path pressure (the gauge pressure is a negative value) at a high speed, so that the first air static pressure-dynamic pressure conversion is completed. The heat exchange air flow flowing into the air suction port of the centrifugal fan at high speed is boosted by the centrifugal fan and sent into the air exhaust cavity 3 with positive pressure relative to the atmospheric environment, and is ejected out from the air outlet 31 at high speed. In the embodiment, the heat exchange air flow is from the air inlet 11 to the air outlet 31 of the main machine, and is subjected to twice static pressure-dynamic pressure conversion by taking the centrifugal fan as power, so that the high-speed suction of the centrifugal fan and the high-speed discharge of the exhaust cavity are realized.
When the host fusion body of the single-air-channel double-refrigerating system is arranged in an orthogonal mode on the air inlet surface and the air outlet surface of the embodiment to operate, the microscopic process that air flows in and out of the fin gaps and flows at a low speed in the fin gaps is a key link of the external heat exchanger 2 in and out of the air field.
At the section of the air inlet E-E, medium-speed air flow of about 4m/s flowing in from the outer vertical surface of the equipment platform is pushed to the section F-F of the fin gap inlet in a uniform laminar flow mode, the line of the air inlet air flow at the section F-F and the fins at the back side of the gap form an obtuse angle relation, and the fins at the back side of the gap are used as a plane cutter to plane a piece of air flow from the air inlet main body air flow and plug into the fin gap; the main body air inlet airflow which is "dug" is intercepted by the blade tip of the "fin planer" at the F-F position, and the main body air inlet airflow impinges on the blade tip of the "planer" of the fin at the back side of the gap at an obtuse angle, and is diffused and decelerated in the fin gap after being reflected by the fin at the front side of the gap; the air flow which is planed by the fin planing tool and is subjected to collision diffusion deceleration is pulled by the negative pressure of the negative pressure cavity of the external heat exchanger at about 1.5m/s, and flows out of the fin channels against the resistance of the fin clearance channels; the low-speed air flow reaching the G-G section of the fin gap outlet is accelerated again to a medium-speed air flow of about 4m/s under the negative pressure pulling of the negative pressure cavity, and is collected and discharged at the H-H section.
The embodiment realizes the innovation of a large-span structure for the air inlet flow path and the air outlet flow path of the outer heat exchanger 2.
When the host fusion of the embodiment operates, on the refrigerant loop, the compressor drives closed-loop circulation and phase-change heat exchange of the refrigerant to couple heat absorption and release of air flow on the air path of the condenser evaporator: the components of a refrigerating circuit element such as a compressor, a four-way valve, an expansion valve, a gas-liquid separator and the like in the compressor cavity, an external heat exchanger, a refrigerant connecting pipe, an indoor unit heat exchanger and the like form an air conditioner refrigerant circulation circuit according to the sequence of the compressor, the four-way valve, the condenser, the expansion valve, the evaporator, the four-way valve, the gas-liquid separator and the compressor; the compressor is used as refrigeration cycle loop power, a high-low pressure state of a refrigerant is respectively established in a condenser evaporator pipeline, the refrigerant is driven to circularly flow and repeatedly change phase in the refrigeration cycle loop to realize 'heat transfer', namely, the refrigerant liquid evaporates and absorbs heat in the evaporator pipeline and absorbs heat of low-temperature ambient air flowing through fin gaps through a giant fin heat absorption area of a copper pipe rising joint, high-temperature high-pressure refrigerant gas condenses and releases heat in the condenser pipeline and releases heat to high-temperature ambient air flowing among fins through a giant fin heat release area of the copper pipe rising joint, and heat transfer from a low-temperature air environment of an air conditioner evaporator to a high-temperature air environment of the condenser is realized.
The air path of the embodiment is single-channel and adopts the diving type air exhaust section, and the double refrigeration systems can independently operate, namely, the two sets of refrigeration systems can synchronously operate or asynchronously operate.
