Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving heat exchange devices, and in particular to a heat recovery fresh air dehumidifier and a dehumidification method thereof. Background Art

[0002] A dehumidifier is also called a dehumidifier, dryer, or dehumidifier. A fan draws humid air into the machine, and the water molecules in the air are condensed into water droplets through two hydrophilic devices (condenser and evaporator). The water collection tray inside the machine is connected to the drain pipe to discharge the precipitated water, thus achieving the dehumidification effect. This cycle keeps the indoor humidity at an appropriate relative humidity.

[0003] In addition, some air-conditioning units that use one compressor to achieve the function of fresh air dehumidification are launched on the market. The defect of this air-conditioning unit is that while dehumidifying the fresh air, the indoor temperature cannot be kept stable and fluctuates greatly, resulting in poor comfort of the indoor environment. It cannot replace the air-conditioning unit with a separate dehumidification system provided in the patent document with patent publication number US20170115014A1 to dehumidify the fresh air while keeping the indoor temperature constant.

[0004] Meanwhile, the prior art also has the following defects: 1. In the dehumidification process of existing fresh air dehumidification equipment, indoor exhaust air is directly discharged to the outside, and the heat in it is usually not effectively recovered. Especially in cold or hot climate conditions, the unused exhaust air heat is directly wasted, resulting in the need for additional energy to heat or cool the fresh air during fresh air treatment, which in turn increases energy consumption.

[0005] 2. Traditional fresh air dehumidification equipment relies on a condenser to cool the air below the dew point for dehumidification, but the dehumidified air is usually low temperature. If this cold air is directly sent indoors, it may cause the indoor air to be too cold, affecting the comfort of the living environment.

[0006] 3. In the long-term operation of traditional dehumidification equipment, the condensed water discharge system is often simple or unintelligent, which is prone to excessive water accumulation leading to system failure, especially in an environment with high humidity.

[0007] 4. The existing fresh air dehumidification equipment has a scattered structure, and multiple functional units operate independently, resulting in low heat exchange efficiency during airflow processing and low energy efficiency of the equipment. At the same time, the heat between fresh air and exhaust air is not effectively transferred, and the air treatment effect is not ideal.
