一种露点追踪除湿调温空调机组

Abstract

本实用新型涉及除湿空调机组，具体涉及一种露点追踪除湿调温空调机组；机头的进风口与出风口之间设有除湿换热盘管和调温盘管；除湿换热盘管的进液口、出液口均与除湿空调热泵机组连通；调温盘管的进液口、出液口均与恒温装置连通；除湿换热盘管的横截面为正方形，除湿换热盘管横截面的一条对角线与机头的进风口方向相同；室内的湿热空气由机头的进风口进入机头内部后与除湿换热盘管的表面换热，湿热空气与除湿换热盘管的外表面接触冷凝形成水珠；湿热空气经除湿换热盘管除湿降温后与调温盘管换热，并由机头的出风口排出。本实用新型通过增加除湿换热盘管与进入机头内的湿热空气的接触面积进而维持较高的除湿效率。

Claims

1. A dew point tracking dehumidifying air conditioning unit, characterized by: It includes a head unit (1) and a dehumidifying air conditioning heat pump unit (2) used in conjunction with the head unit (1); the head unit (1) is provided with a multi-layered staggered dehumidifying heat exchange coil (3) and a temperature regulating coil (4) between the air inlet (5) and the air outlet (6) of the head unit (1); The inlet and outlet of the dehumidifying heat exchange coil (3) are connected to the dehumidifying air conditioning heat pump unit (2), and the chilled water circulates between the dehumidifying heat exchange coil (3) and the dehumidifying air conditioning heat pump unit (2). The inlet and outlet of the temperature regulating coil (4) are connected to the constant temperature device, and the temperature regulating medium circulates between the constant temperature device and the temperature regulating coil (4). The dehumidifying heat exchange coil (3) has a square cross-section, and one diagonal of the cross-section of the dehumidifying heat exchange coil (3) is in the same direction as the air inlet (5) of the head (1). The hot and humid air in the room enters the interior of the unit (1) through the air inlet (5) and exchanges heat with the surface of the dehumidifying heat exchange coil (3). The hot and humid air condenses and forms water droplets when it comes into contact with the outer surface of the dehumidifying heat exchange coil (3), and slides down the outer surface of the dehumidifying heat exchange coil (3). After the hot and humid air is dehumidified and cooled by the dehumidifying heat exchange coil (3), it exchanges heat with the temperature regulating coil (4) and is discharged from the air outlet (6) of the unit (1).

2. The dew point tracking desiccant thermosiphon air conditioning unit of claim 1, wherein: The dehumidifying air conditioning heat pump unit (2) includes an evaporator (21), a compressor (22), a condenser (23), and an expansion valve (24) connected in sequence to form a closed loop; The heat exchange chamber inlet and outlet of the evaporator (21) are connected to the outlet and inlet of the dehumidification heat exchange coil (3) through the outlet pipe (25) and return pipe (26), respectively. A circulation pump (27) is provided on the return pipe (26).

3. The dew point tracking dehumidifying thermosiphon air conditioning unit according to claim 1 or 2, characterized in that: The chilled water temperature at the inlet of the dehumidifying heat exchange coil (3) is 7-10℃, and the chilled water temperature at the outlet is 13-16℃.

4. The dew point tracking desiccant thermosiphon air conditioning unit of claim 3, wherein: The dehumidifying heat exchange coil (3) is provided with multiple fins that are evenly distributed, and the distance between two adjacent fins is 3.5-7mm.

5. The dew point tracking desiccant thermosiphon air conditioning unit of claim 4, wherein: The spacing between two adjacent fins is 3.7 mm.

6. The dew point tracking desiccant thermosiphon air conditioning unit of claim 5, wherein: The outer surface of the dehumidifying heat exchange coil (3) and the fins is provided with a hydrophobic nanolayer.
