Description

Technical Field

[0001] This utility model relates to the field of cooling system technology, specifically a novel typhoon-resistant refrigeration system. Background Technology

[0002] Existing conventional refrigeration systems all use existing freshwater or seawater cooling systems on ships or offshore engineering projects to continuously exchange heat between the condenser and the heat exchanger, thereby achieving the effect of heat exchange and refrigeration. The design of this type of system needs to ensure that the cooling system can meet the refrigeration requirements of the cold storage under normal operating conditions.

[0003] Because the cooling system is a relatively large system, and its operation involves many auxiliary devices, if the entire large cooling system is left unsupervised after personnel are evacuated during typhoon prevention / avoidance, it not only poses safety risks but also wastes energy. Therefore, refrigeration systems using fresh water or seawater cooling have certain limitations during typhoon prevention / avoidance. At present, the refrigeration systems of ships or marine engineering projects also cannot meet the requirements of ship owners or owners for the preservation and storage of food in cold storage.

[0004] Document CN 221316651 U discloses a marine LNG cold energy cascade recovery and utilization system, including an LNG storage tank, a first heat exchanger, a seawater heating module, a third heat exchanger, an auxiliary refrigeration module, and a cold storage unit. The LNG storage tank is connected to the cold end inlet of the first heat exchanger; the hot end outlet of the first heat exchanger is connected to the hot end inlet of the third heat exchanger, and the hot end outlet of the third heat exchanger is connected to the inlet of the cold storage unit or a cold energy user; the outlet of the cold storage unit is connected to the inlet of a second refrigerant variable frequency pump, and the outlet of the second refrigerant variable frequency pump is connected to the hot end inlet of the first heat exchanger; the cold end inlet and outlet of the third heat exchanger are connected to the auxiliary refrigeration module. This structure has poor heat exchange efficiency and requires workers to monitor it, which is quite cumbersome.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned issues, this utility model discloses a novel typhoon-resistant cold storage system. High-temperature liquid refrigerant is cooled by an outdoor air-cooled unit and then repeatedly circulated to achieve the purpose of lowering the storage temperature. This improves the cooling effect while reducing costs and ensuring personnel safety.

[0007] The technical solution of this utility model is as follows: a novel typhoon-resistant refrigeration system, comprising an air-cooled cooling unit, an energy storage tank, and a control box. The control box is connected to sensors in sequence. The air-cooled cooling unit is connected to the energy storage tank and the control box. The control box is connected to compressor a and compressor b. The air-cooled cooling unit is connected to condenser a and condenser b through safety valves. The air-cooled cooling unit cools the refrigerant in condenser a and condenser b through evaporator coils.

[0008] By adopting the above technical solution, the heat generated by the high-temperature and high-pressure liquid refrigerant produced by compressors a and b after compressing the refrigerant is carried away by the outdoor air-cooled cooling unit, thereby reducing the high-temperature and high-pressure liquid refrigerant to a low-temperature and high-pressure liquid refrigerant. It is then sent to the air cooler in each food warehouse through the pipeline system to absorb heat and become a low-pressure and high-temperature gas. After passing through the outdoor air volume unit, the cold zone becomes a low-temperature and high-pressure gas, and then the cycle is repeated to reduce the warehouse temperature.

[0009] Preferably, the air-cooled cooling fan unit is connected to a shut-off valve SV-5 via a safety valve, and the shut-off valve SV-5 is connected to shut-off valves SV-3 and SV-4 respectively.

[0010] Preferably, shut-off valve SV-3 and shut-off valve SV-1 are connected, and the two are connected to compressor a through an oil separator. Shut-off valve SV-1 is connected to condenser a.

[0011] Preferably, shut-off valve SV-4 and shut-off valve SV-2 are connected, and the two are connected to compressor b through an oil separator. Shut-off valve SV-2 is connected to condenser b.

[0012] Preferably, condenser a and condenser b are simultaneously connected to shut-off valve SV-6, shut-off valve SV-6 is connected to energy storage accumulator through shut-off valve SV-8, and energy storage accumulator is connected to air-cooled cooling unit through shut-off valve SV-7.

[0013] Preferably, the air-cooled cooling unit includes an energy storage accumulator and a fan, with the evaporator coil located between the fan and the energy storage accumulator, and a shock-absorbing pad provided at the bottom of the air-cooled cooling unit.

[0014] By adopting the above technical solution, the evaporator coil cools the refrigerant transported from compressor a or compressor b, and the energy storage accumulator stores the cooled refrigerant, which is convenient for transporting the refrigerant to condenser a and condenser b later. The shock-absorbing pads at the bottom of the air-cooled unit can play a role in shock absorption, so that the air-cooled unit will not vibrate or generate noise during operation.

[0015] Preferably, the distance between the air-cooled cooling unit and compressor a and compressor b does not exceed 35m.

[0016] By adopting the above technical solution, the air-cooled cooling unit can quickly cool the coolant transmitted from the compressor, thereby improving the cooling efficiency.

[0017] The advantages of this utility model are as follows: 1. This utility model cools the high-temperature and high-pressure liquid refrigerant generated after compression and refrigeration by passing it through an evaporator coil, thereby meeting the requirements for compressor use.

[0018] 2. This utility model can effectively ensure the operation of the cold storage system after personnel are evacuated during typhoon prevention or avoidance, allowing the entire large-scale cooling system to operate safely in an unsupervised environment, reducing safety risks and saving resources.

[0019] 3. In this invention, the high-temperature liquid refrigerant is cooled by an outdoor air-cooled cooling unit and then repeatedly circulated to achieve the purpose of reducing the temperature of the storage room. This improves the cooling effect while reducing costs and ensuring personnel safety. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1-5As shown, a novel typhoon-resistant refrigeration system includes an air-cooled cooling unit 1, an energy storage tank 2, and a control box 6. The control box 6 is connected to sensors in sequence. The air-cooled cooling unit 1 is connected to the energy storage tank 2 and the control box 6. The control box 6 is connected to compressor a3 and compressor b4. The air-cooled cooling unit 1 is connected to condenser a10 and condenser b11 through a safety valve 5. The air-cooled cooling unit 1 cools the refrigerant in condenser a10 and condenser b11 through an evaporator coil 9.

[0024] By adopting the above technical solution, the heat generated by the high-temperature and high-pressure liquid refrigerant produced by compressors a3 and b4 after compressing the refrigerant is carried away by the outdoor air-cooled cooling unit 1, thereby reducing the high-temperature and high-pressure liquid refrigerant to a low-temperature and high-pressure liquid refrigerant. It is then sent to the air cooler in each food warehouse through the pipeline system to absorb heat and become a low-pressure and high-temperature gas. After passing through the outdoor air volume unit, the cold zone becomes a low-temperature and high-pressure gas, and then the cycle is repeated to reduce the warehouse temperature.

[0025] The air-cooled cooling fan unit 1 is connected to a shut-off valve SV-5 16 via a safety valve. Shut-off valve SV-5 16 is connected to shut-off valves SV-3 14 and SV-4 15 respectively. Shut-off valves SV-3 14 and SV-1 12 are connected to each other. The two are connected to compressor a3 via oil separator 20. Shut-off valve SV-1 12 is connected to condenser a10. Shut-off valves SV-4 15 and SV-2 13 are connected to compressor b4 via oil separator 20. Shut-off valve SV-2 13 is connected to condenser b11. Condensers a10 and b11 are simultaneously connected to shut-off valve SV-6 17. Shut-off valve SV-6 17 is connected to energy storage accumulator 2 via shut-off valve SV-8 19. Energy storage accumulator 2 is connected to air-cooled cooling unit 1 via shut-off valve SV-7 18.

[0026] The air-cooled cooling unit 1 includes an energy storage accumulator 2 and a fan 8. The evaporator coil 9 is located between the fan 8 and the energy storage accumulator 2. The bottom of the air-cooled cooling unit 1 is equipped with a shock-absorbing pad 7. The evaporator coil cools the refrigerant transported from compressor a or compressor b. The energy storage accumulator 2 stores the cooled refrigerant, which is convenient for later transport to condenser a10 and condenser b11. The shock-absorbing pad 7 at the bottom of the air-cooled cooling unit 1 can play a role in vibration isolation, so that the air-cooled cooling unit 1 will not vibrate or generate noise during operation.

[0027] The distance between the air-cooled cooling unit 1 and compressors a3 and b4 does not exceed 35m. The air-cooled cooling unit can quickly cool the coolant transferred from the compressor, improving the cooling efficiency.

[0028] According to the system diagram, the system operates during emergency typhoon prevention / avoidance, and the operating status can be selected according to the actual situation: State 1: If compressor a10 is running, shut-off valves SV-1 12 and SV-4 15 should be closed, and shut-off valves SV-3 14 and SV-6 17 should remain open. State 2: If compressor b11 is running, shut-off valves SV-2 13 and SV-3 14 should be closed, and shut-off valves SV-4 15 and SV-6 17 should remain open. State 3: If the ship is using a freshwater or seawater cooling system, then shut-off valves SV-3 14, SV-4 15 and SV-6 17 should be closed, while shut-off valves SV-1 12 and SV-2 13 should remain open.
