Description

Technical Field

[0001] This article relates to a containerized integrated refrigeration system. Background Technology

[0002] During summer production in medium to large-sized workshops, the challenge of high-temperature environments is frequently encountered. Existing workshop refrigeration systems generally suffer from the following problems:

[0003] Traditional refrigeration equipment is mostly of a split structure, with the refrigeration unit, cooling tower and other equipment needing to be installed separately in indoor machine rooms and outdoor sites. This results in low system integration and occupies a lot of space inside and outside the workshop. Especially for temporary or emergency cooling needs, the complex installation process makes it difficult to respond quickly.

[0004] Medium and large workshops have open spaces, and traditional chilled water and cooling pipes need to be laid across areas, which not only increases pipe losses and leakage risks, but also leads to low energy transmission efficiency, slow cooling speed and high energy consumption.

[0005] In summer, the air humidity in workshops is usually high. Although traditional refrigeration systems can cool the air, their dehumidification capacity is limited, easily causing the workshop to become stuffy and humid, affecting the stability of equipment operation and the comfort of employees. In addition, existing systems lack efficient heat recovery and condensate utilization mechanisms, resulting in significant energy waste.

[0006] For medium and large workshops in summer, there is an urgent need for a refrigeration system that is highly integrated, easy to deploy, has good dehumidification effect and high energy efficiency, in order to solve the technical bottlenecks of traditional solutions such as large space occupation, slow response and high energy consumption. Utility Model Content

[0007] This utility model aims to provide a containerized integrated refrigeration system that effectively solves the problems of low integration, slow deployment, insufficient dehumidification, and high energy consumption in existing structures. The specific solution is as follows:

[0008] A containerized integrated refrigeration system includes a container body, the interior of which is provided with an energy storage section and a refrigeration section;

[0009] The energy storage component includes an energy storage battery pack, a heat exchanger, and a dedicated air-cooling system for the battery.

[0010] The refrigeration section includes a rotary dehumidification module, an evaporator, a compressor, a condenser, and a throttling device. The heat exchange medium flowing between the evaporator, compressor, condenser, and throttling device is a refrigerant. A condensate recovery device is provided at the bottom of the evaporator. The condensate recovery device draws condensate into the heat exchanger through a pipeline. The heat exchanger has two closed heat exchange chambers, which are used for the flow of condensate and the flow of hot air, respectively.

[0011] The hot air discharged from the energy storage battery pack through the battery-specific air-cooling system flows through pipelines into the regeneration zone of the rotary dehumidification module and is finally discharged through pipelines.

[0012] The air handling process is as follows:

[0013] S1. The air vent draws air from the workshop into the evaporator for cooling, forming humid and cold air.

[0014] S2. Moist and cold air flows into the moisture absorption area of ​​the rotary dehumidification module for further dehumidification. The dried, low-temperature and low-humidity air is then sent back to the workshop at an angle through the exhaust vent to complete the cooling cycle.

[0015] S3. The external circulating air inlet can be connected to the external fresh air in the workshop through an extended duct. During high-temperature periods, it can be switched to fresh air mode to reduce the cooling load.

[0016] The energy recovery and utilization process is as follows:

[0017] S1. The cold air with a certain humidity discharged from the evaporator flows into the moisture absorption area of ​​the rotary dehumidification module and is then discharged, which heats and regenerates the dehumidification medium to achieve waste heat recovery.

[0018] S2. After the evaporator condensate exchanges heat with the hot air through the heat exchanger, it flows into the water storage tank for storage and can be used for workshop floor cooling or equipment cooling.

[0019] S3. The hot air that has been heated after heat exchange in the condenser is distributed through a three-way pipe. Part of it is directly discharged, and the other part is used to dissipate heat from the energy storage battery pack, thus optimizing heat distribution.

[0020] The corresponding structural design is as follows: the upper surface of the enclosure is equipped with an air inlet, an external circulating air inlet, and a low-temperature and low-humidity exhaust outlet;

[0021] The external recirculation air inlet is connected to the outside of the workshop to be refrigerated via an extended duct;

[0022] Air is drawn from the interior of the workshop to be refrigerated into the heat exchange area of ​​the evaporator through a fan at the air inlet. The evaporator cools the air, and then the air is dehumidified by a rotary dehumidification module before being discharged into the interior of the workshop through a low-temperature, low-humidity exhaust vent, thus completing the refrigeration process.

[0023] To further prevent dust from entering the system, dustproof louvers are provided at the inlets of the air intake and the external circulating air inlet, and the exhaust direction of the low temperature and low humidity exhaust outlet is obliquely upward.

[0024] Furthermore, the heated air in the condenser is connected via a three-way pipe, one outlet of which is directly connected to the external circulating air inlet, and the other outlet of which is connected to the energy storage battery pack.

[0025] Furthermore, the rotary dehumidifier module, evaporator, compressor, condenser, and throttling device are all installed inside a closed housing, the surface of which is provided with corresponding pipes or wiring connectors. The rotary dehumidifier module is a rotating dehumidifier with two independent chambers inside. The upper chamber is the moisture absorption zone, where the silica gel rotor absorbs moisture from the air. The lower chamber is the regeneration zone, where the silica gel rotor rotates to the regeneration zone, and the absorbed moisture is discharged through the surface flow of hot air.

[0026] Furthermore, the energy storage section is located inside the energy storage cavity, which has an L-shaped cross-section. The condenser is located above the energy storage cavity, and the rotary dehumidification module is located at the end of the housing. Between the rotary dehumidification module and the condenser, there is a compressor, a condenser, a throttling device, a water collector, and a water storage tank. The water storage tank is located at the bottom of the rotary dehumidification module, and the water storage tank is equipped with a wastewater direct discharge port.

[0027] To enhance the equipment's usability and convenience, the refrigeration unit can be directly connected to mains power. Furthermore, the enclosure utilizes a standard container structure with pre-assembled internal modules, allowing for rapid transport via forklift or trailer. Power-on testing can be completed within 2 hours, eliminating the need for civil engineering construction. Beneficial effects

[0028] This utility model integrates the energy storage and refrigeration components into the housing. The rotary dehumidification module further dehumidifies the cold air discharged from the evaporator. Combined with the air handling process of the air inlet, external circulating air inlet, and low-temperature and low-humidity exhaust outlet, it achieves rapid cooling and humidity control. It can quickly meet the temporary or emergency cooling needs of medium and large workshops in summer and solve the problems of insufficient dehumidification and large space occupation of traditional systems.

[0029] The system achieves heat exchange and storage of condensate through a condensate recovery device and heat exchanger. It uses hot air from the energy storage battery to heat the regeneration zone of the rotary dehumidification module. At the same time, it rationally distributes the hot air after heat exchange in the condenser through a three-way pipe, effectively improving energy utilization and reducing waste. The system also features a compact structure, convenient deployment, dustproof, noise reduction, and flexible reusability, thus reducing installation and maintenance costs.

[0034] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model. Example

[0035] As shown in Figures 2 and 3, a containerized refrigeration system for emergency cooling in large and medium-sized workshops is described. The container 1 has a steel frame structure with an air inlet 3, an external circulating air inlet 4, and a low-temperature, low-humidity exhaust outlet 2 on its top surface. The air inlet 3 is connected to the air inlet side of the evaporator 7 via a centrifugal fan (not shown in the figure), and the external circulating air inlet 4 is connected to the outside of the workshop to be refrigerated via an extension pipe (not shown in the figure). The interior of the container 1 is divided into an energy storage chamber 5 and a refrigeration chamber.

[0036] The energy storage chamber 5 has an L-shaped cross-section and is equipped with an energy storage battery pack (not shown in the figure), a heat exchanger (not shown in the figure), and a battery-specific air-cooling system (not shown in the figure). The hot air discharged from the battery air-cooling system is introduced into the regeneration zone of the rotary dehumidification module 6 through the hot air outlet pipe 11.

[0037] Inside the refrigeration chamber, the rotary dehumidification module 6 is installed at the end of the housing 1, with its moisture absorption area connected to the air outlet of the evaporator 7. A condensate recovery device (not shown in the figure) is installed at the bottom of the evaporator 7, and the condensate flows into the heat exchanger through a pipeline. The compressor 9, condenser 8, throttling device (not shown in the figure), and water collector (not shown in the figure) are arranged sequentially between the rotary dehumidification module 6 and the condenser 8. The condenser 8 is located above the energy storage chamber 5, and its heat dissipation end is connected to a three-way pipe (not shown in the figure) via a hot air supply pipe 10. The other outlet of the three-way pipe is connected to the heat dissipation channel of the energy storage battery pack. A water storage tank (not shown in the figure) is located at the bottom of the rotary dehumidification module 6 and connected to the heat exchanger outlet pipeline. A wastewater direct discharge port (not shown in the figure) is located at the bottom.

[0038] The entire system achieves modular linkage through pipelines (hot air outlet pipe 11, hot air replenishment pipe 10) and wiring, forming a refrigeration cycle of "induced air cooling → dehumidification → exhaust air" and an energy recovery process of "battery heat dissipation → hot air regeneration dehumidification → waste heat discharge".

[0039] In emergency cooling applications in medium and large workshops, this containerized integrated refrigeration system, with its compact design that integrates energy storage and refrigeration modules, can quickly extract hot air from the workshop through the air inlet, cool it through the evaporator, dehumidify it through the rotary dehumidification module, and then discharge dry, cold air obliquely upward through the low-temperature, low-humidity exhaust outlet. Combined with the introduction of fresh air through the external circulating air inlet, it can achieve rapid deployment and efficient cooling within 2 hours.

[0040] Meanwhile, the hot air from the energy storage battery pack can be used to heat the regeneration zone of the rotary dehumidification module. The hot air from the condenser is distributed to the energy storage battery pack or the external circulating air inlet through a three-way pipe. Combined with the waste heat recovery design of the condensate being stored through a heat exchanger, the energy utilization rate is significantly improved and the operating cost is reduced during emergency cooling, providing the workshop with a flexible, efficient and energy-saving emergency cooling solution.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
