The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or otherwise implying any indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may include one or more of that feature either explicitly or implicitly. In the description of the present application, "a plurality" means two or more unless otherwise specified.

In the description of the present application, it should be noted that the terms "mounted", "connected", and "connected", unless otherwise specifically stated or limited, are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The fresh air humidifying unit integrates the functions of an air conditioner and a fresh air blower and is used for introducing humidified fresh air into a room to regulate indoor air. The fresh air humidity controller is usually provided with at least two heat exchangers, and the two heat exchangers are respectively positioned in different air channels. Because two heat exchangers can alternate the usage between evaporimeter and condenser, consequently all need set up the water collector and carry out the water receiving below the heat exchanger.

If the scheme of two water trays is adopted, one water tray corresponds to one heat exchanger, two sets of drainage systems are needed, the cost of products can be increased, and the process cost is higher.

If a scheme of a common water pan is adopted, a new problem exists:

exemplarily, referring to fig. 12, arrows in the figure indicate air flow direction, two heat exchangers share one water pan 3, a fresh air duct and a return air duct are separated by a partition plate 5, and a space is provided between the lower end of the partition plate 5 and the water pan 3, so that condensed water on two sides of the partition plate 5 can circulate through the space, and water can be drained only by one set of drainage system. However, if the air passages on both sides generate a pressure difference, the air easily flows from one air passage to the other air passage along the gap, causing a problem of wind cross.

For example, referring to fig. 13, if there is no space between the lower end of the partition 5 and the water-receiving tray 3, although there is no problem of wind leakage, it is still essentially equivalent to two water-receiving trays 3, and it is necessary to provide a drain pump 42 for the condensed water on both sides of the partition 5, which increases the cost.

In order to solve the problems, the invention idea of the application is provided, and the structure of the water pan 3 is designed, so that the two heat exchangers share one water pan 3, and wind can not be mixed.

Referring to fig. 1, a fresh air humidity conditioner according to an embodiment of the present application includes an air duct system and a refrigerant system.
