Description

Technical Field

[0001] The present invention belongs to the technical field of green energy saving, and in particular relates to a combined commercial air-conditioning host and equipment platform and an installation method. Background Art

[0002] At present, the application scenarios of commercial air-conditioning hosts have undergone fundamental changes. The host position has been replaced from an open open-air platform without space constraints to a semi-enclosed equipment platform under the conditions of a building distributed energy system; the air inlet and outlet wind field of the air-conditioning host has been transformed from a classic hemispherical three-dimensional open space to a semi-enclosed corridor with a roof, a bottom, a wall at the back, and shutters at the front, which is open on one side.

[0003] To adapt to this change in application scenarios, the air-conditioning industry has carried out continuous technological innovation. For example, Guangzhou Wanerermai Engineering Technology Co., Ltd. has an air-conditioning host with vertically arranged fans and its equipment platform (application number 202310972409.9). In the above-mentioned semi-enclosed building corridor (i.e. embedded equipment platform) scenario, it expands the total ventilation cross-sectional area of ​​the air-conditioning host's external heat exchanger, the total area of ​​the fins, reduces the heat transfer temperature difference of the external heat exchanger body, and constructs a low-resistance external heat exchanger air path that penetrates the equipment platform's facade decoration structure. The air-conditioning host body is designed innovatively to achieve air path coupling and energy coupling between the air-conditioning host and the building's facade decoration structure, laying the technical foundation for "coupled air conditioning":

[0004] like Figure 1 As shown, the patent sets at least one negative pressure chamber of the external heat exchanger, which is composed of a bottom plate, a side plate, a back plate, a fin-tube external heat exchanger and a top plate; a V-shaped external heat exchanger assembly is arranged continuously horizontally relative to the back plate, and an exhaust port of the external heat exchanger negative pressure chamber is arranged on the back plate, and a fan is installed at the exhaust port, including an axial flow fan and a centrifugal fan; a backward-inclined centrifugal fan is preferred, and the air suction port of the backward-inclined outer rotor centrifugal fan faces the external heat exchanger assembly; the V-shaped fin-tube heat exchangers arranged continuously horizontally are the air inlets of the negative pressure chamber; an exhaust chamber is arranged below the bottom plate of the negative pressure chamber (or above the top plate), and the exhaust port of the exhaust chamber is arranged on the same side as the main air inlet of the air-conditioning host, and the air inlet of the exhaust chamber is connected to the continuously arranged V-shaped external heat exchanger negative pressure chamber fan exhaust port; a compressor chamber is arranged on the rear side of the exhaust chamber back plate, and fluorine circuit components such as the four-way valve, expansion valve and electrical box of the air-conditioning host compressor are placed.

[0005] like Figure 2As shown, the patent establishes the inlet and outlet wind field of the V-shaped external heat exchanger assembly continuously arranged in the air-conditioning main unit through the operation of the centrifugal fan: the vertically arranged centrifugal fan draws the air in the negative pressure cavity of the continuously arranged V-shaped external heat exchanger to generate negative pressure in the cavity, and pulls the ambient air into the main unit from the main unit air inlet at medium speed, and the main body air intake air flow is planed by a multi-fin planer to achieve the dispersion and deceleration of the air intake air flow, and the air flow flows through the gap between the fins of the V-shaped external heat exchanger at a low speed to complete the heat exchange, and then enters the negative pressure cavity, and then gathers and accelerates to flow into the centrifugal fan suction port with the lowest pressure, and finally is boosted by the fan, passes through the exhaust cavity and is discharged outward at a high speed.

[0006] The technical advantage of this patent lies not only in the construction of an efficient heat exchange air path structure for the external heat exchanger assembly of the air-conditioning main unit, thereby improving the energy density of the air-conditioning main unit, but more importantly, it creates conditions for building a low-resistance air path structure with same-side entry and exit in coordination with the equipment platform facade: the air inlet and outlet of the air-conditioning main unit are arranged in the same direction, on the same side, and up and down, adjacent to the facade of the equipment platform, and in coordination with the facade to build an air path structure with same-side entry and exit of the air-conditioning main unit, which effectively improves the exhaust speed and kinetic energy of the external heat exchanger of the air-conditioning main unit, and effectively improves the range and diffusion dilution effect of the exhaust jet of the air-conditioning main unit passing through the facade of the equipment platform and entering the ambient atmosphere.

[0007] However, when applying this patented technology, there are still the following important practical technical problems related to scenarios and processes:

[0008] For example, the issue of whether the air conditioner host can be transported vertically by elevator must be resolved. The patent does not define the structural relationship between the main components inside the air conditioner host, such as the compressor chamber, the external heat exchanger assembly, the vertical exhaust chamber, and the longitudinal exhaust chamber, as well as the length, width, and height of the whole machine, and does not resolve the issue of whether the air conditioner host can be transported vertically by elevator; using high-rise building elevators for vertical transportation, delivering commercial air conditioners to the air conditioner positions on the equipment platform, and removing and moving old machines out and then transporting new machines in when the equipment is updated, all require the use of elevators; the dimensions of ordinary elevator cars are usually 2000 long × 1750 deep × 2555 high, and the dimensions of elevator doors are usually 1100 wide and 2100 high, while commercial air conditioners are mostly high-power, which is very likely to exceed the dimensions of the elevator door and the interior space;

[0009] Another example is that the problem of operating space required for machine maintenance must be solved. Because commercial buildings are usually located in advantageous locations and every inch of land is valuable, the equipment platform is relatively crowded; the patent does not solve the problem of the appropriate operating space required for the necessary cleaning and maintenance of the air-conditioning host on the equipment platform, or even for on-site inspection and repair of systemic failures. Summary of the invention

[0025] The vertical exhaust cavity in the external heat exchanger assembly cavity is connected to the longitudinal exhaust cavity, completing the internal air path of the external heat exchanger of the air conditioner main unit and completing the connection of the internal and external air paths of the equipment platform;

[0026] The refrigerant fluorine circuit of the compressor cavity and the external heat exchanger assembly cavity is then connected to form a commercial air-conditioning host unit; after that, it is connected to the fluorine circuit of the plate heat exchanger built into the air-conditioning indoor unit or the host to jointly construct a closed multi-split refrigerant circuit.

[0054] Example 1

[0055] like Figures 3 to 6 As shown, a combined commercial air-conditioning main unit is composed of module assembly, the module includes a compressor cavity 1 provided with a compressor 11, an external heat exchanger assembly cavity 2 provided with an external heat exchanger assembly 21 and a vertical exhaust cavity 22, and a longitudinal exhaust cavity 3 connected with the vertical exhaust cavity 22; the longitudinal exhaust cavity 3 is arranged below the external heat exchanger assembly cavity 2 and is fixedly connected to the bottom plate of the vertical exhaust cavity 22; the compressor cavity 1 is arranged on the side of the longitudinal exhaust cavity 3 and is connected with the fluorine path and the circuit in the external heat exchanger assembly cavity 2; the exhaust port 31 of the longitudinal exhaust cavity 3 is in the same direction as the air inlet 23 of the external heat exchanger assembly 21.

[0056] The horizontal interface dimension of the longitudinal exhaust cavity 3 is greater than or equal to the horizontal cross-sectional dimension of the external heat exchanger assembly cavity 2 .

[0057] The back plate 24 of the external heat exchanger assembly cavity 2 is arranged flush with the back plate 32 of the longitudinal exhaust cavity 3 ; the compressor cavity 1 is arranged on the back plate 32 of the longitudinal exhaust cavity 3 .

[0058] A base 4 is provided at the bottom of the longitudinal exhaust chamber 3 and the compressor chamber 1 .

[0059] The external heat exchanger assembly 21 is a copper tube V-type, copper tube N-type, copper tube M-type or copper tube “IWI” type fin-tube heat exchanger structure composed of at least two flat-plate fin-tube heat exchangers 211 .

[0060] The size of the module is sufficient to fit into a normal elevator car and car door.

[0061] This embodiment continues to inherit the design technologies used by the commercial air-conditioning host, such as the zigzag external heat exchanger assembly cavity 2, the air inlet 23 and the exhaust outlet 31 arranged on the same side and up and down, the expansion of the top space of the equipment platform 5, and the construction of a low-resistance external heat exchanger air duct of the decorative mechanism 51 that penetrates the outer facade of the equipment platform. In response to the problems in the background technology, this embodiment focuses on two scenario-related and process-related practical technical problems: the use of ordinary elevators to vertically transport the air-conditioning host and the operating space required for the inspection and maintenance of the air-conditioning host on the equipment platform 5. The commercial air-conditioning host is structurally decoupled and modularly designed, and the commercial air-conditioning host is decoupled into at least three first-level components, such as the compressor cavity 1, the external heat exchanger assembly cavity 2, and the longitudinal exhaust cavity 3. The size of each first-level component is designed to meet the requirements of vertical transportation by ordinary elevators.

[0062] The three primary components of this embodiment, namely the compressor cavity 1, the longitudinal exhaust cavity 3, and the external heat exchanger assembly cavity 2, have uniformly planned and balanced technical parameters and structural dimensions, are independently designed and manufactured, and are transported in batches to the commercial building equipment platform site by elevator, and then assembled into a commercial air-conditioning host machine; finally, the fluorine circuit and the circuit of the air-conditioning host and the air-conditioning indoor unit are connected to jointly construct a closed multi-split refrigerant circuit.

[0063] In this embodiment, a commercial host machine is constructed of three primary components, namely, a compressor cavity 1, a longitudinal exhaust cavity 3, and an external heat exchanger assembly cavity 2. The external heat exchanger assembly cavity 2 and the longitudinal exhaust cavity 3 are upper and lower two-stage structures, and the compressor cavity 1 is attached to the two-stage structure.

[0064] In this embodiment, the three sides of the longitudinal exhaust chamber 3 as the lower section of the two-section structure extend outward, that is, the horizontal interface size of the longitudinal exhaust chamber 3 is greater than or equal to the horizontal cross-sectional size of the external heat exchanger assembly chamber 2.

[0065] The lateral extensions on its left and right sides expand the width of the longitudinal exhaust chamber 3, reduce the height of the longitudinal exhaust chamber 3 and the vertical ratio of the height of the longitudinal exhaust chamber 3 on the outer facade of the equipment platform, and set a lower limit for the lateral spacing between adjacent main units; the longitudinal extension section on its front side is inserted forward above the anti-ridge 53 of the equipment platform 5 above the base 4, and docks with the exhaust port preset on the outer facade; the longitudinal extension section on its front side is connected with the lateral extension sections on both sides to form a platform-type waistline of the air-conditioning main unit, providing the necessary operating space for the operator to install, inspect, maintain and dismantle the cavity of the heat exchanger assembly outside the air-conditioning main unit.

[0066] The secondary components of the three primary components of this embodiment are as follows:

[0067] ① The external heat exchanger assembly cavity 2 includes the external heat exchanger assembly 21, the backward centrifugal fan 25, the vertical exhaust cavity 22, etc. The external heat exchanger assembly 21 is arranged on the air inlet surface of the air inlet 23 of the external heat exchanger assembly cavity 2, and forms a heat exchanger assembly negative pressure cavity connected to the heat exchange air path of the external heat exchanger assembly 21 with part of the outer shell; an air outlet is arranged on the back plate of the negative pressure cavity of the heat exchanger assembly, and two backward centrifugal fans 25 and the vertical exhaust cavity 22 are installed at the air outlet.

[0068] ② The longitudinal exhaust cavity body 3 includes a longitudinal exhaust cavity 33 connected to the vertical exhaust cavity 22 and a transversely extending exhaust section 34; the exhaust port 31 of the longitudinal exhaust cavity body 3 faces the short side of the air conditioner mainframe.

[0069] ③ Compressor chamber body 1, including compressor 11, gas-liquid separator 12, four-way valve 13, electrical box 14, etc.

[0070] In this embodiment, the backward-facing centrifugal fan 25 in the heat exchanger assembly cavity 2 is the biggest constraint in meeting the structural design conditions of the air-conditioning host for elevator transportation because the outer diameter of the impeller significantly exceeds the diameter of the impeller air suction port. In this embodiment, a backward-facing centrifugal fan 25 with low static pressure, large air volume and low noise is adopted. Under the condition that the diameter of the impeller air suction port is determined, the outer diameter of the impeller is greatly reduced to reduce the constraint of the centrifugal fan on the structural design of the host.

[0071] The external heat exchanger assembly cavity of this embodiment adopts a flat-plate fin-tube heat exchanger 211 to form a copper tube "IWI" type fin-tube heat exchanger body structure; wherein, the copper tube W-shaped fin-tube heat exchanger part relies on the front air inlet surface to supply air; the copper tube I-shaped fin-tube heat exchanger parts on both sides, in addition to a small amount of air supply from the front air inlet surface, mainly use the horizontal intervals on both sides of the air conditioner main unit to supply air.

[0072] Example 2

[0073] The present embodiment and embodiment 1 both focus on two scenario-based and process-based practical technical issues, namely, using ordinary elevators to vertically transport air-conditioning hosts and the operating space required for overhauling and servicing the air-conditioning hosts on the equipment platform. Structural decoupling and modular design are implemented for commercial air-conditioning hosts, and the commercial air-conditioning hosts are decoupled into at least three first-level components, namely, a compressor cavity, an external heat exchanger assembly cavity, and a longitudinal exhaust cavity. The size of each first-level component is designed to meet the requirements of vertical transportation by ordinary elevators. Moreover, the technical parameters and structural dimensions of the three first-level components are uniformly planned and balanced, and they are independently designed and manufactured. They are transported to the equipment platform site by elevator and then assembled into a complete commercial air-conditioning host.

[0074] like Figure 7 As shown, the difference of this embodiment is that the external heat exchanger assembly 21 adopts a copper tube M-type fin tube heat exchanger.

[0075] In this embodiment, since the external heat exchanger assembly 21 adopts a copper tube M-type fin-tube heat exchanger, the structure is simpler than the "IWI" structure of Embodiment 1 and is more suitable for relatively low-power models.

[0076] Example 3

[0077] like Figures 8 to 10 As shown, an equipment platform 5 for setting a combined commercial air conditioner host, the exhaust port 31 of the longitudinal exhaust cavity 3 is aligned with the low-position exhaust port 52 reserved on the building facade, and the air inlet 23 of the external heat exchanger assembly cavity 2 is aligned with the decorative mechanism 51 in the middle and upper part of the building facade;

[0078] The upper surface of the longitudinal exhaust chamber body 3 forms a maintenance platform.

[0079] At least one row of modular commercial air-conditioning main units is arranged in the equipment platform 5 in the horizontal direction.

[0080] The equipment platform 5 includes a counter-slope 53 , a crossbeam 55 , a column 54 , a decorative mechanism 51 and a low-position exhaust port 52 .

[0081] A method for installing a modular commercial air conditioner host on an equipment platform comprises the following steps: using an elevator to transport each module, including a compressor cavity 1, a longitudinal exhaust cavity 3, and an external heat exchanger assembly cavity 2, to the floor where the equipment platform 5 is located, and then transporting it to the equipment platform site;

[0082] At the equipment platform site, the longitudinal exhaust cavity 3, the external heat exchanger assembly cavity 2, and the compressor cavity 1 are assembled in sequence, with the exhaust port 31 of the longitudinal exhaust cavity 3 aligned with the low exhaust port 52 reserved on the exterior facade 58, and the air inlet 23 of the external heat exchanger assembly cavity 2 aligned with the transparent decorative structure 51 in the middle and upper part of the equipment platform exterior facade 58;

[0083] The vertical exhaust cavity 22 of the external heat exchanger assembly cavity 2 is connected to the longitudinal exhaust cavity 33, completing the internal air path of the external heat exchanger of the air conditioner main unit and completing the connection of the internal and external air paths of the equipment platform;

[0084] The refrigerant fluorine path of the compressor cavity 1 and the external heat exchanger assembly cavity 2 is then connected to form a commercial air-conditioning host unit; thereafter, it is connected to the refrigerant fluorine path 56 of the air-conditioning indoor unit 7 or the plate heat exchanger built into the host to jointly construct a closed multi-unit refrigerant circuit.

[0085] The longitudinal extension section on the front side of the longitudinal exhaust chamber body 3 of the combined commercial air-conditioning main unit of the present embodiment, together with the lateral extension sections on both sides thereof, are connected to form a platform-type waistline of the main unit, that is, the upper surface of the longitudinal exhaust chamber body 3 constitutes a maintenance platform, which provides an important operating space for operators to carry out installation, inspection and maintenance operations on the heat exchanger cavity outside the air-conditioning main unit.

[0086] When this embodiment is in operation, the ambient fresh air passes through the middle and upper decorative mechanism 51 (such as blinds) on the outer facade of the equipment platform over a large area, at a low speed and with low resistance, and then passes through the front air inlet surface of the external heat exchanger assembly cavity 2 of the air-conditioning main unit and the air supply slits on both sides to enter the external heat exchanger assembly 21. After heat exchange, it is sucked in and pressurized by the backward centrifugal fan 25 and sent into the vertical exhaust cavity 22 in the external heat exchanger assembly cavity 2, and then turns into the bottom longitudinal exhaust cavity 33. Finally, it is ejected at a high speed from the exhaust section exhaust port of the longitudinal exhaust cavity 3 extending forward of the low-position exhaust port 52 reserved for the outer facade, and discharged into the ambient atmosphere for diffusion and dilution.

[0087] Example 4

[0088] like Figures 11-12 As shown, a method for installing the combined commercial air-conditioning host on a device platform, based on Example 3, further includes the following steps:

[0089] The combined commercial air-conditioning host is arranged between the columns 54 of the equipment platform and is arranged starting from the column 54, that is, the column 54 is the starting point for the arrangement of the combined commercial air-conditioning host; a larger interval 57 is left in the middle between the two columns 54. When a combined commercial air-conditioning host fails and needs to be removed for repair or equipment update, the air-conditioning host can be moved sequentially to the middle interval 57 to make room for disassembling and repairing the failed machine or dividing it into modules and moving it out of the equipment platform.

[0090] The modular commercial air conditioner mainframes are arranged at intervals. The maintenance platform formed by the intervals between the modular commercial air conditioner mainframes and the upper surface of the longitudinal exhaust cavity 3 is sufficient to realize the operation space for maintenance and the like.

[0091] The modular commercial air conditioner host is arranged near the outer facade 58 of the equipment platform; a three-in-one passage is formed between the back plate of the modular commercial air conditioner host and the inner wall of the equipment platform for pedestrians, maintenance, and installation of internal and external unit connection pipes 8 and bridges 9. The three-in-one passage serves as a stationary area and buffer zone for the air conditioner host, realizing the sequential movement of multiple air conditioner hosts, and realizing the longitudinal and lateral large-scale movement of a single air conditioner host under specific functional goals, which is convenient for installation, maintenance, and maintenance.

[0092] The fluorine circuit connecting pipe 8 between the indoor and outdoor units of the air conditioner includes a connecting section 81 connected to the air conditioner main unit, a vertical section 82, and a three-dimensional inclined section 83; the connecting section 81 of the indoor and outdoor unit connecting pipe 8 is connected to the vertical section 82, and then bent vertically upward at an obtuse angle to form a three-dimensional inclined section 83 that goes up and connects to the copper pipe on the bridge frame 9.

[0093] The three-dimensional inclined section 83 is extended in three dimensions, vertically, horizontally and longitudinally, or the three-dimensional inclined section 83 is S-shaped and bent upward, connecting the copper pipe on the bridge frame 9. The horizontal length of the three-dimensional inclined section 83 is not less than the width of two air conditioner hosts 2.

[0094] This embodiment installs an air-conditioning main unit that can move in three dimensions when the refrigerant pipes of the internal and external machines are connected, and innovates the spatial structural relationship between the multi-split air-conditioning main unit, connecting copper pipes, bridge frames and equipment platforms to achieve the goal of "on an equipment platform where the multi-split air-conditioning main units are densely arranged, only the position of the multi-split air-conditioning main unit needs to be moved without emptying the refrigerant and without disconnecting the copper pipes of the internal and external machines to implement inspection and maintenance of some built-in components of the multi-split unit."

[0095] In this embodiment, each copper tube is first vertically upward and then bent at an obtuse angle to enter the connecting bridge 9. The connecting copper tube lags behind the air-conditioning host body by more than 2 machine widths before entering the connecting bridge 9, and the connecting copper tube is elastically suspended. This ensures that when the air-conditioning host implements longitudinal, transverse and vertical three-dimensional movement, the internal and external unit connecting copper tube 8 located on the chassis of the air-conditioning host can move accordingly without causing wrinkles in the connecting copper tube and irreversible damage to its strength.

[0096] In this embodiment, when the air-conditioning main unit is moved, the pipe opening of the connecting copper tube located on the chassis of the air-conditioning main unit can move accordingly with the air-conditioning main unit, and because the total length of the vertical copper tube and the upward copper tube that form an obtuse bend from the pipe opening on the chassis of the air-conditioning main unit to the fixed position where the connecting copper tube enters the connecting bridge 9 exceeds 5 meters, sufficient elastic space is provided for the movement of the pipe opening without causing wrinkles or irreversible damage to the strength of the connecting copper tube; thus, on the equipment platform, it is only necessary to move the position of the multi-split air-conditioning main unit to the inside of the maintenance aisle to open the structure of the multi-split air-conditioning main unit, and to carry out inspection and maintenance of the built-in components of the multi-split part without emptying the refrigerant and without untying the connection between the copper tubes of the internal and external units.
