Description

Technical Field

[0001] The present invention relates to the technical field of chillers, in particular to a marine air-suspended variable-frequency centrifugal chiller. Background Art

[0002] With the booming development of the modern shipping industry, the functions of ships are becoming increasingly diversified, and the requirements for refrigeration systems are becoming more and more stringent. Traditional marine refrigeration units generally have the problem of high energy consumption. They consume a lot of fuel during long voyages, which not only increases operating costs but also aggravates environmental pollution. At the same time, their maintenance process is complicated, requiring professionals to regularly inspect and lubricate mechanical bearings and other components. The slightest negligence may cause failures. Moreover, when ships encounter harsh sea conditions during navigation, the stability of traditional units is difficult to guarantee, and the cooling effect often fluctuates, seriously affecting the lives of crew members and the safety of cargo.

[0003] Prior art, such as Chinese Patent Publication No. CN107101406A, discloses a marine constant-temperature chiller comprising a compressor, an air-cooled condenser, an expansion valve, an evaporator, a constant-temperature merging water tank, a return pump, and a circulating pump. The system also includes a temperature sensor, an electric heater, a flow sensor, and a three-way valve. The temperature sensor is installed on the chilled water pipe. When the temperature sensor detects fluctuations in the chilled water temperature, a central control system controls the electric heater to maintain the chilled water temperature at a set value. The flow sensor is installed within the chilled water pipe. When the flow sensor detects a mismatch between the flow rate and the designed flow rate, the central control system controls the three-way valve to adjust the chilled water flow rate to maintain the set value. Compared to prior art, the present invention features a simple principle and structure, minimizes temperature fluctuations, achieves high system energy efficiency, and offers relatively low overall operating costs.

[0004] When the centrifugal chiller in the prior art is in use, it is necessary to separately set up corresponding evaporation mechanisms and condensation mechanisms to achieve circulation. However, the traditional condensation structure and evaporation mechanism are mostly split-type distribution structures, which will cause inconvenience due to occupying a large space under the premise of relatively narrow space on the ship. In addition, when it is in use, it also lacks an effective ambient wind utilization structure. When it is hot in summer and cold in winter, it cannot use external ambient wind for auxiliary temperature control evaporation or condensation, which has limitations.

[0005] Therefore, we proposed a marine air-suspended variable frequency centrifugal chiller in order to solve the problem that the centrifugal chiller in the prior art proposed in the above background technology needs to be equipped with corresponding evaporation mechanism and condensation mechanism respectively to realize circulation when in use, and the traditional condensation structure and evaporation mechanism are mostly split distribution structures, which will cause inconvenience due to occupying a large space under the premise of relatively narrow space on the ship, and it also lacks an effective ambient wind utilization structure when in use. It cannot utilize external ambient wind for auxiliary temperature control evaporation or condensation in high temperature in summer and low temperature in winter, and there are limitations.

[0019] 3. When the present invention is used, a driving structure combining air bearings and variable frequency motors is adopted. Compared with traditional mechanical bearings, air bearings achieve contactless suspension support through the airflow provided by the air supply pump, completely eliminating the loss and potential faults caused by mechanical friction. There is no need for regular lubrication and maintenance, which simplifies the maintenance process and reduces the dependence on professional maintenance. At the same time, the variable frequency motor can dynamically adjust the speed according to the actual cooling demand, avoiding the energy waste under the fixed speed of the traditional unit. The contactless operation feature enables the unit to maintain stable operation under harsh sea conditions, ensuring stable cooling effect, protecting the life of crew members and the safety of cargo, and comprehensively optimizing the performance of the marine chiller in terms of energy consumption, maintenance and stability.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-9 As shown, the present invention provides a technical solution: a marine air suspension variable frequency centrifugal chiller, comprising a support mechanism 1, characterized in that the support mechanism 1 is provided at two locations, and the inner sides of the two support mechanisms 1 are fixedly connected to an evaporation mechanism 2 and a condensation mechanism 2013; The evaporation mechanism 2 and the condensation mechanism 2013 are both arc-shaped structures with a hollow interior, and the evaporation mechanism 2 and the condensation mechanism 2013 are arranged opposite to each other at the inner sides of the two support mechanisms 1, and the inner sides of the two support mechanisms 1 are also fixedly connected with a partition assembly 2012, the partition assembly 2012 is located at the inner sides of the evaporation mechanism 2 and the condensation mechanism 2013, and the right side of the partition assembly 2012 is fixedly connected with a cover mechanism 3, and a cavity is provided inside the partition assembly 2012, which is a heat-insulating cavity 20121, and the heat-insulating cavity 20121 is used to isolate the evaporation mechanism 2 from absorbing the heat released by the condensation mechanism 2013, and an insulation core 20122 is fixedly connected to the inner wall of the insulation cavity 20121, and the insulation core 20122 is used to prevent heat transfer, and the cover mechanism 3 is a conical barrel structure, and the right side of the cover mechanism 3 is opened in a linear array. There are two through holes, and a filter assembly 301 is fixedly connected to the inner opening of the cover body mechanism 3. There are four filter assemblies 301 in total, where every two laterally adjacent filter assemblies 301 form a group, and the two groups of filter assemblies 301 are fixedly connected in a linear array at the upper and lower sides of the interior of the cover body mechanism 3. A servo motor 3011 is also installed on the right side of the two groups of filter assemblies 301, and a fan blade assembly 3012 is installed on the left output shaft of the servo motor 3011. The fan blade assembly 3012 and the servo motor 3011 together constitute an auxiliary air supply structure. The condensing mechanism 2013 is installed on the top of the evaporating mechanism 2 through the mounting assembly 2016. The outer peripheral surface of the wind tube assembly 3013 is provided with air outlet holes 3017 in a ring array, and the inner side of the cover body mechanism 3 is fixedly connected with an inner partition 3018 for separating the two groups of filter assemblies 301.

[0023] In this embodiment, when in use, the two supporting mechanisms 1 serve as the supporting frame of the overall structure, and the evaporating mechanism 2 and the condensing mechanism 2013 are vertically connected by an inner fixed connection, which changes the traditional horizontal side-by-side arrangement to a vertical side-by-side arrangement, and this structural change is only for the purpose of changing the horizontal side-by-side arrangement that originally occupies a larger area to a longitudinal side-by-side arrangement that occupies a smaller area, which does not affect the normal working effects of the evaporating mechanism 2 and the condensing mechanism 2013. Both the evaporating mechanism 2 and the condensing mechanism 2013 adopt an internal hollow arc structure. This arc design not only reduces the resistance of the fluid during internal flow, but also fits tightly to the inner side of the two supporting mechanisms 1 by being arranged in opposite directions, thereby minimizing the gap between the two. Moreover, by the arrangement of the partition assembly 2012 and the heat-insulating inner cavity 20121 and the heat-insulating inner core 20122, compared with the traditional in-line vertical side-by-side evaporating mechanism 2 and the condensing mechanism 2013, heat exchange interference can be effectively reduced. The inner sides of the two support mechanisms 1 are also fixedly connected with a partition assembly 2012. The partition assembly 2012 is located inside the evaporation mechanism 2 and the condensation mechanism 213. It can not only achieve physical separation between the two to prevent the internal media from interfering with each other, but also enhance the stability of the overall structure through the fixed connection with the support mechanism 1 to prevent the mechanism from being displaced due to turbulence during navigation. Four outrigger assemblies 101 are fixedly connected to the bottom surface of the support mechanism 1. Every two longitudinally adjacent outrigger assemblies 101 form a group. Two groups of outrigger assemblies 101 are distributed opposite each other at the bottom end of the support mechanism 1. The gasket assemblies 1011 at the bottom end are fixed to the hull through the mounting holes at the four corners. The gasket assemblies 1011 can buffer the vibration of the ship during navigation, further improving the stability of the overall structure. The front and rear sides of the two supporting mechanisms 1 are fixedly connected with outer guard plates 1012. The outer guard plates 1012 can not only protect the internal mechanisms from external collisions and seawater erosion, but the control terminal 1013 on the front outer guard plate 1012 can also centrally control the overall operation, avoiding the cumbersomeness of the scattered setting of multiple control units in the split structure. Through the integrated structural design, while ensuring the independent functions of each mechanism, the space occupied on the ship is significantly reduced.

[0024] Example 2: Figure 1-Figure 5 As shown, a hot water inlet pipe 201 is fixedly connected to the upper side of the left end surface of the evaporation mechanism 2, and a cold water discharge pipe 2011 is also fixedly connected to the left end surface of the evaporation mechanism 2, and the hot water inlet pipe 201 and the cold water discharge pipe 2011 are circulated through a copper pipe, and a cold water inlet pipe 2014 and a hot water discharge pipe 2015 are also fixedly connected to the left side of the condensation mechanism 213, and the cold water inlet pipe 2014 and the hot water discharge pipe 2015 are connected through a copper pipe set in the condensation mechanism 213, and the partition assembly 2012 is used to separate the evaporation mechanism 2 and the condensation mechanism 213, and the cover A through hole is provided on the left side of the body mechanism 3, and there are two through holes in total, and the two through holes are respectively located at the upper and lower sides of the partition assembly 2012. The wind tube assembly 3013 is inserted into the through hole in the cover body mechanism 3. The main body of the wind tube assembly 3013 is an internal hollow structure, and a magnetic limit plate 3014 is fixedly connected to the left side surface of the wind tube assembly 3013. The diameter of the magnetic limit plate 3014 is larger than the diameter of the wind tube assembly 3013. The magnetic limit plate 3014 is used to be adsorbed and connected with the left end surface of the cover body mechanism 3, and the magnetic limit plate 3014 is an electromagnet structure that generates magnetism when energized.

[0025] In this embodiment, when in use, a cone-shaped cover mechanism 3 is fixedly connected to the right side of the partition assembly 2012. Two filter assemblies 301 arranged in a linear array are fixedly connected to the inner side of the cover mechanism 3. The filter assemblies 301 can filter the incoming air to prevent impurities from entering the evaporation mechanism 2 and the condensation mechanism 2013 and affecting their operation. The left side of the cover body mechanism 3 is provided with two through holes, which are respectively located on the upper and lower sides of the partition assembly 2012. The air duct assembly 3013 inserted in the through hole is an internal hollow structure. The magnetic limit plate 3014 on the left side is an electromagnet structure that generates magnetism when energized. When it is necessary to use the ambient wind, the control terminal 1013 controls the magnetic limit plate 3014 to be powered off. After the magnetism disappears, the spring structure of the reset assembly 3016 on the side of the magnetic limit plate 3014 close to the cover body mechanism 3 will push the magnetic limit plate 3014 to drive the air duct assembly 3013 to move to the left, so that the left end of the air duct assembly 3013 extends out of the through hole, opening the channel for the ambient wind to enter. The annular limiting baffle 3015 on the right side of the air duct assembly 3013 can prevent the air duct assembly 3013 from escaping from the inside of the cover body mechanism 3, ensuring the safety of the structure. The servo motor 3011 installed on the right side of the two sets of filter assemblies 301 is started according to actual needs. For example, when the servo motor 3011 on the right side of the upper right filter assembly 301 is started, the fan blade assembly 3012 on the left output shaft rotates to form an auxiliary air supply structure. When the temperature is high in summer, the fan blade assembly 3012 introduces the external environment wind through the air duct assembly 3013 and blows it toward the steam The evaporation mechanism 2 is activated to assist the evaporation mechanism 2 in heating and evaporating. In winter, when the temperature is low, the servo motor 3011 located on the upper right is activated to introduce cold air to the condensing mechanism 213, thereby assisting in improving the condensing efficiency. By flexibly utilizing the ambient air, the energy consumption of the unit itself is reduced. The internal partition 3018 is separated and cooperates with the partition assembly 2012 to form two independent air flow channels, which do not interfere with each other. The evaporation mechanism 2 and the condensing mechanism 2013 can use their own air flow channels to independently realize their respective functions. When there is no need to utilize the ambient wind, the control terminal 1013 controls the magnetic limit plate 3014 to be energized to generate magnetism, so that it is adsorbed with the left end face of the cover mechanism 3, driving the wind tube assembly 3013 to move to the right, closing the through hole, and preventing the adverse external environment from affecting the internal mechanism. This adjustable ambient wind utilization structure breaks through the limitation that traditional units cannot utilize natural wind according to seasonal temperature changes, and improves the adaptability and energy saving of the unit.

Air bearings 4012 are provided on the left and right sides of the shell component 4011. The output shaft of the variable frequency motor 401 is connected to the air bearing 4012 and is located on the inner side of the shell component 4011. An impeller assembly 4013 is installed on the right output shaft of the variable frequency motor 401. The impeller assembly 4013 is located on the inner side of the shell component 4011, and the impeller assembly 4013, the shell component 4011 and the variable frequency motor 401 together constitute a compressor structure, and the front end face of the connecting bracket 4 is fixedly connected to the air supply Pump 4014, the air supply pump 4014 is fixedly connected to the air outlet side on the rear side with an air supply pipe 4015, there are two air supply pipes 4015, and the two air supply pipes 4015 are respectively connected to the two air bearings 4012, the bottom end of the shell component 4011 is fixedly connected to an extraction pipe 4016, the extraction pipe 4016 is connected to the evaporation mechanism 2, and the top end of the shell component 4011 is fixedly connected to a supply pipe 4017, the side of the supply pipe 4017 away from the shell component 4011 is connected to the condensing mechanism 2013, and the right end surface of the support mechanism 1 on the right side is fixedly connected to a platen mechanism 5, the top surface of the platen mechanism 5 is fixedly connected to an air radiator 501, and the condensing mechanism A condensation outlet pipe 5011 is installed on the right side of 2013 through a water pump. The condensation outlet pipe 5011 circulates through the air radiator 501. The top of the air radiator 501 is fixedly connected to a flash assembly 5012. The side of the condensation outlet pipe 5011 away from the condensing mechanism 2013 is connected to the flash assembly 5012, and the top of the flash assembly 5012 is fixedly connected to an air supply pipe 5013. The side of the air supply pipe 5013 away from the flash assembly 5012 is connected to the extraction pipe 4016, and a return circulation pipe 5014 is installed on the rear side of the flash assembly 5012 through a throttling control valve 5015. The side of the return circulation pipe 5014 away from the throttling control valve 5015 is connected to the evaporation mechanism 2.

[0027] In this embodiment, when in use, the connecting bracket 4 located at the front end face of the front outer guard plate 1012 is a U-shaped structure with a one-way opening at the rear side. The variable frequency motor 401 fixedly connected to the left side thereof can adjust the output speed according to the cooling demand. The internal hollow shell assembly 4011 fixed inside provides installation space for the compressor structure. The air bearings 4012 on the left and right sides of the shell assembly 4011 are supplied with high-pressure gas through two air supply pipes 4015 by the air supply pump 4014 at the front end face of the connecting bracket 4, so that an air film is formed between the air bearings 4012 and the output shaft of the variable frequency motor 401, realizing contactless suspension support and completely eliminating the mechanical friction of traditional mechanical bearings. The right output shaft of the variable frequency motor 401 is mounted with an impeller assembly 4013 located inside the housing assembly 4011. Together, the three components form a compressor structure. When the variable frequency motor 401 drives the impeller assembly 4013 to rotate, low-pressure refrigerant vapor is extracted from the evaporation mechanism 2 through an extraction pipe 4016 at the bottom end of the housing assembly 4011. After compression, it becomes high-pressure, high-temperature vapor, which is then fed into the condensing mechanism 2013 through a supply pipe 4017 at the top end of the housing assembly 4011 for condensation. The condensation outlet pipe 5011 connected to the right side of the condensing mechanism 2013 via a water pump sends the condensed refrigerant into the air radiator 501 on the top of the platen mechanism 5 on the right support mechanism 1 for further heat dissipation. The condensed refrigerant then enters the flash assembly 5012. The flash gas separated in the flash assembly 5012 returns to the extraction pipe 4016 through the air supply pipe 5013, improving the efficiency of the compressor. The liquid refrigerant then enters the evaporation mechanism 2 through the rear throttling control valve 5015 and the return circulation pipe 5014, completing the refrigeration cycle. Since the air bearing 4012 does not require lubrication, the tedious process of regular lubrication and maintenance of traditional mechanical bearings is reduced, reducing maintenance costs and the risk of failure; the speed adjustment function of the variable frequency motor 401 can accurately match the unit's output power with the actual cooling demand, avoiding the energy waste of traditional fixed-speed units; the contactless suspension operation mode reduces the impact of mechanical vibration when the ship encounters severe sea conditions, ensures the stability of the cooling effect, and solves many disadvantages of traditional units.
