What is Wrap-Around Heat Pipe?
The U-type Wrap-Around Dehumidification Heat Pipe is a high-efficiency and energy-saving equipment independently developed by Beijing Detian Dixing Technology Development Co., Ltd. With an innovative design, it provides auxiliary precooling/preheating functions for air treatment systems, helps surface air coolers improve dehumidification capacity and reduces system energy consumption at the same time. Widely applied in the field of air treatment in humid environments, it offers energy-saving and comfortable environmental solutions for users.
The Impact of Indoor Humidity on Health
Health Benefits of Optimal Humidity
Maintaining optimal indoor relative humidity is critical for human health. It significantly minimizes the survival and impact of harmful factors like viruses, molds, mites, and respiratory infections.
The Vital Role of Wrap-Around Heat Pipes
Achieving this strict moisture control highlights the importance of wrap-around dehumidification heat pipes. They efficiently stabilize humidity to prevent biological contamination and improve air quality in an energy-saving manner.
Core Functions of Wrap-Around Heat Pipe
Assisting in Improving Dehumidification Efficiency
Without additional power, it helps surface air coolers enhance dehumidification capacity through precooling/preheating, effectively reducing air humidity.
Assisting in Environmental Optimization of Air Conditioning Systems
The fresh air is precooled and preheated by the U-type Dehumidification Heat Pipe, which can help air conditioning systems improve the quality of fresh air.
Energy Saving and Consumption Reduction
By optimizing heat exchange efficiency, it reduces the cooling ton demand of the system, and some configurations can achieve a 30% energy saving effect.
Working Principle of Wrap-Around Heat Pipe
After the humid and hot air is precooled by the U-type Dehumidification Heat Pipe, it enters the coil/surface air cooler for deep treatment, where water condenses and is discharged, and dry and comfortable air is finally output. The whole process is free of mechanical drive, and relies on natural heat exchange to assist in improving dehumidification efficiency while reducing the energy consumption of the air conditioning system.
Technical Advantages
Improved Dehumidification Efficiency
Enhanced performance of surface air coolers: The precooling section lowers the air dew point temperature, increasing the dehumidification capacity of surface air coolers by more than 15% and reducing the burden of condensed water discharge at the same time.
High Efficiency, Energy Saving and Consumption Reduction
Sensible heat recovery technology: The heat pipe recovers heat from hot, humid air, reducing the need for steam or electricity. It can save about 30% energy compared with electric reheating.
Bidirectional energy-saving design: Precooling reduces the cooling load, while reheating uses recovered heat to warm dehumidified air without extra energy use.
Compact Structure and Strong Adaptability
No moving parts: The equipment operates in a fully passive mode without external power, featuring high reliability and a service life of more than 10 years.
High space utilization: The U-type structure can share space with cold coils, suitable for the transformation of air conditioning units and saving installation costs.
Low Maintenance Cost
Maintenance-free design: No internal moving mechanical parts, ensuring stable operation.
Corrosion resistance: Adopting hydrophilic aluminum foil or stainless steel materials, it is adaptable to humid environments and prolongs the service life of the equipment.
Environmental Protection and Safety
Reduced pollution emissions: Fossil energy consumption is lowered through waste heat recovery, indirectly reducing carbon emissions.
