Embodiment 1

[0031] refer to figure 1 The fresh air dehumidification device provided by an embodiment of the present invention includes: an air-conditioning pipeline, a sensible heat exchanger 7, a surface cooler 9, and a fan 10 arranged in the air-conditioning pipeline. The air-conditioning pipeline includes an air supply pipeline and an exhaust air pipeline. The air supply pipeline is provided with a fresh air outlet 4 for communicating with outdoor fresh air and an air supply outlet 11 for supplying air to the room, and the exhaust pipeline is provided with a return air outlet 1 for returning indoor air and for exhausting indoor air. Exhaust air outlet 2.

[0032] Among them, the sensible heat exchanger 7 and the surface cooler 9 are sequentially arranged on the air supply pipeline, the sensible heat exchanger 7 is a cross-flow plate heat exchanger, and the air inlet is connected with the flow channel inlet on one side of the cross-flow plate heat exchanger. The outlet of the flow chan...

Embodiment 2

[0038] refer to figure 2 , in order to improve the cleanliness of the air, in this embodiment, a filter device is also arranged in the air supply pipeline, and the filter device is arranged between the fresh air outlet 4 and the sensible heat exchanger 7 . In this embodiment, the filtering device is two filters, which are the primary filter 5 and the PM2.5 filter 6 respectively. The large particle pollutants in the air are filtered through the primary filter 6, and then further filtered through the PM2.5 filter 6 to make the air cleaner and prevent air pollution from affecting the health of the human body. During specific implementation, there may be more than three filters, so as to improve the filtering effect.

Embodiment 3

[0040] refer to image 3 , in order to improve the dehumidification effect during the return air mode and prevent the fresh air outlet 4 from entering the air, the fresh air dehumidification device of this embodiment also includes a vent valve 12 for controlling the opening or closing of the fresh air outlet 4 and the exhaust outlet 2, when the fresh air dehumidification device When in the air return mode, the ventilation valve 12 is closed.

Abstract

The invention provides a fresh-air dehumidifier comprising an air-conditioning pipeline, a sensible heat exchanger, a surface air cooler and an air blower arranged in the air-conditioning pipeline. The air-conditioning pipeline comprises an air supply pipeline and an air discharge pipeline, the air supply pipeline is provided with a fresh air inlet used for communicating with outdoor fresh air and an air supply outlet used for supplying air to the indoors, and the air discharge pipeline is provided with a return air inlet used for backflow of indoor air and an air outlet used for discharging indoor exhaust air. The fresh-air dehumidifier is high in dehumidification efficiency and low in energy consumption.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fresh air dehumidification device. Background technique [0002] The fresh air system is based on sending fresh air to the room with special equipment on one side of the closed room, and then exhausting it from the other side to the outside by special equipment. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. While supplying air, it can also dehumidify the air entering the room. [0003] However, the current fresh air dehumidifiers generally have the following problems: 1. Insufficient dehumidification capacity in a high-humidity environment or when the indoor humidity load increases; 2. High energy consumption. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a fresh air dehumidification device with high dehumidification efficiency and low energy consumption. [0005]...
