Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment component technology, and in particular to a modularly installed chiller unit. Background Technology

[0002] Water chillers remove liquid vapor through compression or heat absorption refrigeration cycles to achieve a cooling effect. Their refrigeration system mainly consists of four core components: a compressor, evaporator, condenser, and expansion valve. These components are connected by copper pipes to form a closed-loop system. An appropriate amount of refrigerant is charged into the system, and under the action of the compressor, the refrigerant circulates within the system to achieve the cooling effect.

[0003] For example, a modular air-cooled chiller unit disclosed in a Chinese patent (publication number CN211204478U) specifically discloses a unit including a fixed frame, a compressor, a protective cover, a connecting plate, and an air inlet grille. It also includes an expansion valve, a knob, a plate, and a protective net. The compressor is vertically mounted inside the upper part of the fixed frame. A circular ventilation hole is provided on the top of the fixed frame corresponding to the compressor, and an installation port for the expansion valve is provided on the side of the fixed frame. This modular air-cooled chiller unit has a clever and reasonable structure, facilitating assembly and installation, making it convenient to use and cost-effective. The expansion valve drives the compressor, which receives gas through the air inlet grille and ventilation hole. After processing by the compressor, the gas is output through the exchange port of the connecting plate.

[0004] Existing air-cooled modular chillers are divided into single-cooling and heat pump types. In the market, air-cooled modular chillers generally refer to heat pump type air-cooled modular chillers, also known as air-cooled heat pump units. Due to design limitations, existing air-cooled modular chillers are mostly designed for single-use applications and cannot adjust the number of modules in operation according to load conditions. Therefore, we propose a modularly installed chiller unit. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modularly installed chiller unit, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a modularly installed chiller unit, comprising: a frame, wherein a plurality of mounting holes are provided on the frame, a partition is fixedly installed inside the frame, the partition is hollow inside, a support member is fixedly installed at the bottom of the partition, the support member is hollow inside, and the lower end of the support member is fixed inside the frame.

[0007] An exhaust pipe is connected to and fixedly installed on the support member, and the exhaust pipe is connected to the inner cavity of the support member. A connecting pipe is installed between the support member and the partition, and the support member and the partition are connected through the connecting pipe. Two spaced-apart first pipes are connected to and fixedly installed on the top of the partition. Two spaced-apart compressors are provided inside the frame. The first pipes are connected to the exhaust pipes of the compressors. An air inlet pipe is fixedly installed on the top of the frame. Two symmetrically distributed connecting mechanisms are provided at the lower end of the air inlet pipe, and the air inlet pipe is connected to the air inlet pipe of the compressor through the connecting mechanisms.

[0008] As a further technical solution of this utility model, the connecting mechanism includes a second pipe that is connected to and fixedly installed on the air inlet pipe. The port of the second pipe is configured to be outwardly flared, and the end of the air inlet pipe is configured to be conical. The end of the air inlet pipe matches the shape of the port of the second pipe. The end of the air inlet pipe is inserted into the port of the second pipe and the two are connected. Valves are installed on both of the second pipes.

[0010] As a further technical solution of this utility model, a second sealing gasket is fixedly installed inside the exhaust pipe of the compressor.

The slide rails are fixed on the frame, with one end of the slide rail blocked and the other end open. Slide bars are fixed on both sides of the compressor and are slidably arranged in the slide rails.

[0012] As a further technical solution of this utility model, two spaced limiting mechanisms are provided between the two compressors.

[0013] This utility model provides a modularly installed chiller unit, which has the following advantages compared with the prior art:

[0014] Beneficial effects:

[0015] 1. This design is a modularly installed chiller unit. By controlling the opening and closing of the second pipeline with a valve, when the valve is closed, the second pipeline cannot introduce refrigerant gas into the compressor. This allows the number of operating compressor module components to be adjusted according to the load, thereby achieving on-demand cooling or heating and reducing the unit's operating energy consumption.

[0016] 2. This design presents a modular chiller unit that utilizes a sliding installation method for the compressor modules. A rotating limit bar restricts the compressor's movement, facilitating easy assembly and disassembly of the compressor modules and simplifying subsequent maintenance. When a compressor module malfunctions, it can be quickly removed for repair or replacement without affecting the normal operation of other modules. This helps reduce downtime and improves system reliability and stability. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a modular installation solution for a chiller unit: A modular installation chiller unit includes: a frame 1 with multiple mounting holes; a partition 2 fixedly installed inside the frame 1, the partition 2 being hollow; a support member 3 fixedly installed at the bottom of the partition 2, the support member 3 being hollow, and its lower end fixed inside the frame 1; an exhaust pipe 4 connected and fixedly installed on the support member 3, communicating with the inner cavity of the support member 3; a connecting pipe 5 installed between the support member 3 and the partition 2, connecting the support member 3 and the partition 2; two spaced-apart first pipes 6 connected and fixedly installed at the top of the partition 2; two spaced-apart compressors 7 located inside the frame 1; the first pipes 6 communicating with the exhaust pipes 10 of the compressors 7; an intake pipe 8 fixedly installed at the top of the frame 1, with two symmetrically distributed connecting mechanisms at the lower end of the intake pipe 8, connecting the intake pipe 8 to the intake pipes 9 of the compressors 7.

[0024] The connecting mechanism includes a second pipe 11 that is connected to and fixedly installed on the air inlet pipe 8. The port of the second pipe 11 is set to be outwardly flared, and the end of the air inlet pipe 9 is set to be conical. The end of the air inlet pipe 9 matches the shape of the port of the second pipe 11. The end of the air inlet pipe 9 is inserted into the port of the second pipe 11 and the two are connected. A valve 18 is installed on the second pipe 11.

[0025] Refrigerant gas is introduced through inlet pipe 8 and compressed by compressor 7. After being compressed into a high-temperature, high-pressure gas in compressor 7, the refrigerant enters the condenser to exchange heat with the air and condenses into a liquid. Then, the liquid refrigerant enters the evaporator, where it absorbs heat and evaporates into gas. Finally, the refrigerant gas is drawn back into compressor 7 to begin a new cycle.

[0026] The refrigerant gas in the inlet pipe 8 is split by the second pipes 11 on both sides, and then enters the compressor 7 through the inlet pipe 9. The exhaust pipe 10 introduces the high-temperature and high-pressure gas into the first pipe 6, and then enters the connecting pipe 5 through the partition 2. After passing through the inner cavity of the support 3, it is discharged to the condenser through the exhaust pipe 4.

[0027] By controlling the opening and closing of the second pipeline 11 through valve 18, when valve 18 is closed, the second pipeline 11 cannot introduce refrigerant gas into the compressor 7, thereby adjusting the number of operating modules of the compressor 7 according to the load, realizing on-demand cooling or heating, and reducing the energy consumption of the unit.

[0028] A first sealing gasket 12 is fixedly installed inside the port of the second pipe 11. A second sealing gasket 13 is fixedly installed inside the exhaust pipe 10 of the compressor 7. The first sealing gasket 12 and the second sealing gasket 13 can improve the sealing performance. Slides 14 are provided on both sides of the compressor 7. The slides 14 are fixed to the frame 1. One end of the slide 14 is blocked and the other end is open. Slide strips 15 are fixed on both sides of the compressor 7 and are slidably disposed in the slides 14. Two spaced limiting mechanisms are provided between the two compressors 7. The limiting mechanism includes a mounting base 16 fixedly installed on the frame 1. A limiting strip 17 is rotatably installed on the mounting base 16 and can be rotated to one side of the compressor 7.

[0029] When the compressor module 7 is not in use, the compressor 7 can be removed. Rotating the limiting strip 17 away from one side of the compressor 7 allows the compressor 7 to slide. The slide bar 15 slides within the slide rail 14, separating the exhaust pipe 10 from the first pipe 6 and the intake pipe 9 from the second pipe 11. When adding the compressor module 7, the compressor 7 is pushed into the frame 1. The slide bar 15 slides into the slide rail 14, connecting the exhaust pipe 10 to the first pipe 6 and the intake pipe 9 to the second pipe 11. Rotating the limiting strip 17 and locking it to one side of the compressor 7 then limits its movement. Therefore, the assembly and disassembly of the compressor module 7 is convenient, and subsequent maintenance is simple and efficient. When a compressor module 7 malfunctions, it can be quickly removed for repair or replacement without affecting the normal operation of other modules. This helps reduce downtime and improves system reliability and stability.

[0030] The working principle of this invention is as follows: Refrigerant gas is introduced through the inlet pipe 8. The compressor 7 compresses the refrigerant gas, transforming it into a high-temperature, high-pressure gas. This gas then enters the condenser to exchange heat with air and condense into a liquid. The liquid refrigerant then enters the evaporator, where it absorbs heat and evaporates back into gas. Finally, the refrigerant gas is drawn back into the compressor 7 to begin a new cycle. The refrigerant gas in the inlet pipe 8 is diverted by the second pipes 11 on both sides, then enters the compressor 7 through the inlet pipe 9. The exhaust pipe 10 guides the high-temperature, high-pressure gas into the first pipe 6, then through the partition 2 into the connecting pipe 5, and finally through the inner cavity of the support member 3 before being discharged to the condenser through the exhaust pipe 4. By controlling the opening and closing of the second pipes 11 with the valve 18, the second pipes 11 cannot introduce refrigerant gas into the compressor 7, thus adjusting the number of compressor 7 modules operating according to the load.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
