Description
Technical Field
[0001] This utility model relates to the field of uninterrupted antifreeze protection technology for outdoor air source chiller units, specifically an uninterrupted antifreeze protection device for outdoor air source chiller units. Background Technology
[0002] Commercial and industrial air conditioning outdoor units are core equipment for temperature control in large buildings and industrial settings. They need to meet the requirements of high load and continuous operation. Their technological development revolves around improving energy efficiency and environmental adaptability. These outdoor units often adopt multi-split or composite heat exchange system designs. The fluorinated water heat exchanger is one of the core components. Through the coil structure composed of copper tubes and fins, heat transfer between refrigerant and circulating water is realized, thereby completing the cooling or heating of the environment.
[0003] In environments with power outages and low temperatures, the hot water pipes of fluorinated water heat exchangers are prone to freezing. After a power outage, the system circulation stops, and the water remaining in the pipes loses its flow momentum. Affected by the low external temperature, the water continues to cool down until it freezes. After freezing, the water volume expands, which may damage the pipe structure. More importantly, the ice layer will block the heat exchange path between the water pipes and the refrigerant, preventing the refrigerant from transferring heat through the heat exchanger. Existing antifreeze measures mostly rely on electric preheating or temperature control by circulating pumps during operation. After a power outage, these mechanisms fail, ultimately causing the entire heat dissipation system to malfunction, requiring shutdown for maintenance and potentially triggering a chain reaction of equipment damage. Utility Model Content
[0004] The purpose of this invention is to provide an uninterrupted antifreeze protection device for outdoor air source chiller / hot water units. It has the advantages of being resistant to power outages and low temperatures, and solves the problem in existing commercial or industrial air conditioning outdoor units where the hot water pipes of the refrigerant heat exchanger are easily frozen in low-temperature environments after a power outage, causing the water in the refrigerant heat exchanger to be unable to exchange heat with the refrigerant, resulting in the failure of the entire heat dissipation system.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An uninterrupted antifreeze protection device for outdoor air source chiller / hot water unit, comprising a heat dissipation assembly, characterized in that it further includes a heat exchange antifreeze assembly, a main pump, and a pressurization and insulation assembly.

[0006] Preferably, the heat dissipation fins are fixedly connected to the inverted triangular bracket.
[0007] It is worth noting that by fixing the heat dissipation fins to the inverted triangular bracket, the structural stability of the heat dissipation component can be enhanced. This ensures that the heat dissipation fins can maintain a stable relative position under the influence of the cooling fan and the external environment, thus guaranteeing that the heat dissipation area of the heat dissipation fins is fully expanded and improving the heat dissipation efficiency of the heat dissipation component.
[0008] Preferably, a cooling fan is installed at the upper end of the inverted triangular bracket.
[0009] It is worth noting that a cooling fan is installed at the top of the inverted triangular bracket, which allows the airflow generated by the cooling fan to pass through the heat dissipation fins more efficiently, accelerates the airflow speed around the heat dissipation fins, and thus quickly removes the heat from the heat dissipation fins, further improving the heat dissipation performance of the heat dissipation component.
[0010] Preferably, the heat dissipation fins are a combination of heat dissipation fins and refrigerant pipes.
[0011] It is worth noting that the heat sink fins adopt a combination of heat sink fins and heat pipes. This structure can efficiently transfer refrigerant through the heat pipes and increase the contact area with air by means of the heat sink fins, thereby significantly improving heat exchange efficiency and ensuring the heat dissipation effect of the heat dissipation component on the refrigerant.
[0012] Preferably, there are two UPS booster pump modules; each UPS booster pump module includes a small booster pump and a UPS power supply, and the power control program of the UPS power supply is directly written into the controller of the air conditioner outdoor unit for joint control and operation, and the UPS power supply provides power to the UPS insulation heating element, the finned UPS heating element, and the small booster pump.
[0013] It is worth noting that: setting up two UPS booster pump modules can form redundant protection and improve the reliability of the water circulation antifreeze protection; together with the UPS power supply of the UPS booster pump module, even when the external power supply is interrupted, it can still supply power to the finned UPS heating element and UPS insulation heating element, avoiding the water in the heat exchange pipeline of the fluoride water heat exchanger from freezing due to power outage; and the electrical control program is integrated with the air conditioner outdoor unit controller, which can realize automated and timely antifreeze control, accurately start heating according to parameters such as water temperature, and ensure the timeliness of antifreeze protection.
[0014] Preferably, the water temperature sensor is connected to the electronic controller of the air conditioner outdoor unit for information transmission.
[0015] It is worth noting that: connecting the connectors, water temperature sensor, and water pressure gauge through pipelines ensures the integrity of the water flow path; the water temperature sensor is connected to the electronic controller for information transmission, and can feed back the monitored water temperature data to the electronic controller in real time, so that the electronic controller can promptly determine whether the UPS booster pump module needs to be activated for antifreeze; at the same time, the water pressure gauge can monitor the pressure in the pipeline in real time, making it easy to detect abnormalities such as leaks and blockages in the pipeline, ensuring the safety and stability of the entire system operation.
[0016] Preferably, the water supply pipe connects the water pressure gauge, UPS booster pump module, valve, and connector in series; the two UPS booster pump modules pump water in opposite directions.
[0017] It is worth noting that ensuring the circulation and heat dissipation of water during the heat dissipation process also allows the heat generated by the UPS booster pump module to be evenly transferred to the entire pipeline system, improving the comprehensiveness and efficiency of antifreeze protection and enhancing the overall insulation effect of the water circuit.
[0018] Preferably, the output end of the main pump is connected to the refrigerant pipe of the heat sink fins via a pipeline; the input end of the main pump is connected to the refrigerant output end of the fluorine-water heat exchanger via a pipeline.
[0019] It is worth noting that the main pump, as the power source for the refrigerant, drives the refrigerant to circulate efficiently between the refrigerant heat exchange zone of the fluorine-water heat exchanger and the refrigerant pipes of the heat sink fins, ensuring the normal operation of the air conditioning system's refrigeration cycle, thereby improving the air conditioning system's refrigeration efficiency and operational stability.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with two UPS booster pump modules with UPS power supply to form redundant protection. The UPS power supply can provide power to the finned UPS heating element, UPS insulation heating element and small booster pump when the external power supply is interrupted, so as to avoid the water in the heat exchange pipeline of the fluorine water heat exchanger freezing due to power outage, and improve the reliability and continuity of antifreeze protection.
[0021] The water temperature sensor is connected to the air conditioner outdoor unit's electronic controller for information transmission, enabling real-time feedback of water temperature data. Combined with the electronic control program integrated into the air conditioner outdoor unit's controller, it can automatically and promptly activate antifreeze measures. At the same time, the water pressure gauge in the pipeline monitors the pressure in real time, facilitating the timely detection of pipeline abnormalities and ensuring the safety and stability of the system operation.
