Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fresh air system technology, more exactly, to a double cold source fresh air dehumidifier. BACKGROUND

[0002] With the improvement of people's requirements for indoor air quality, and the continuous development of domestic real estate and decoration market, the market demand for fresh air dehumidifiers is growing. Domestic enterprises continue to invest in the research and development of fresh air dehumidifiers, and launch new products with high efficiency, energy saving, intelligent control and other characteristics. For example, double cold source fresh air dehumidifier improves the dehumidification efficiency through double cold source technology, while reducing energy consumption.

[0003] Double cold source fresh air dehumidifier is a device for adjusting indoor air humidity and temperature. It combines the functions of fresh air system and dehumidifier, and can provide fresh air while dehumidifying the air. The vertical double cold source fresh air dehumidifier includes a casing, a compressor, a surface cooler, an evaporator and a condenser and other components. Its working principle is that outdoor fresh air first enters the device through the fresh air inlet, and is filtered by the primary filter and the high efficiency filter. The filtered fresh air enters the surface cooler for preliminary cooling and dehumidification. Then, the fresh air enters the evaporator and condenser components, and is further cooled and dehumidified by the refrigerant. During the dehumidification process, the running state of the refrigerant compressor can be adjusted to control the temperature of the air sent into the room.

[0004] The surface cooler is an important component of the double cold source fresh air dehumidifier. Its working principle is to exchange heat between the cooling medium (such as water or refrigerant) in the coil and the air, thereby reducing the temperature and humidity of the air. The surface cooler has a set of coils inside, and the cooling medium (such as cold water or refrigerant) flows in the coils. When the air passes through the surface cooler, it exchanges heat with the outer wall of the coil, and the heat of the air is absorbed by the cooling medium in the coil, thereby reducing the temperature of the air. However, in winter, especially in the north, the cooling water left in the coil is easy to freeze, and in severe cases, it can freeze the coil and damage the surface cooler, causing the double cold source fresh air dehumidifier to be unusable.
