Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification equipment, and in particular to a fresh air duct dehumidifier with an air purification function. Background Art

[0002] A fresh air duct dehumidifier with an air purification function is a composite device that integrates fresh air ventilation, humidity adjustment, and air purification.

[0003] For the dehumidifier, it mainly involves two processes. The first is the process of introducing and treating fresh air, and the second is the process of air transportation and circulation. First, outdoor air is inhaled into the device through a pipeline system to achieve the replacement of indoor and outdoor air; high-efficiency filters (such as HEPA filters) are used to remove particulate matter, and gaseous pollutants (such as formaldehyde and odors) and microorganisms are eliminated through technologies such as activated carbon adsorption and negative ion sterilization; the condensation dehumidification technology is used to reduce the humidity of the air; then, the temperature of the dehumidified air is adjusted through a heat exchange module so that the air entering the room reaches room temperature. Finally, the treated dry and clean air is transported to each room through pipelines to form a dynamic cycle, effectively avoiding local humidity or air pollution.

[0004] Since the dehumidifier dehumidifies through the condensation dehumidification technology, when the air passes through the condensation pipe, the moisture in the air is precooled and liquefied, so as to separate the moisture from the air; however, the condensation dehumidification depends on the temperature difference between the evaporator and the air to condense the moisture. When in a low-temperature environment, the cooling capacity of the evaporator is limited, the temperature difference shrinks, resulting in the inability of water vapor to be fully condensed into liquid water; low temperature will cause the viscosity of the compressor lubricating oil to increase, the refrigerant circulation resistance to rise, and the refrigeration capacity of the compressor to decrease, thus affecting the overall dehumidification performance. Some models will trigger a protection mechanism to stop when the temperature is below 5°C; in a low-temperature environment, the surface of the evaporator is prone to frosting, blocking the air flow path, and the defrosting program (stopping or reverse heating) needs to be frequently started, resulting in a shortened effective dehumidification time and limited use scenarios of the dehumidifier.
