Abstract
The utility model discloses an air source heat pump water circulation heating and water circulation condensation dehumidification drying device which conducts heating through air source heat pump water circulation heating and conducts dehumidification through water circulation condensation dehumidification. In the process of dehumidification, when air in a drying room flows through fin-type heat exchanger of dehumidification, heat of the air is absorbed, and the temperature of the air drops. When the temperature of moisture of airflow is below zero, the moisture is condensed and becomes water which is discharged from the drying room. After the dehumidified air flows through a fin-type heat exchanger of heating, the air is heated, and the temperate of the air rises. Therefore, after the air is dehumidified in the drying room, the humidity is reduced and the temperature almost does not drop, energy is saved, consumption is reduced, exhaust gas and waste residue will not be generated, and the environment will not be polluted. The air source heat pump water circulation heating and water circulation condensation dehumidification drying device is convenient to operate and control and easy to install and relocate due to the fact that when the device is installed and relocated, just a connecting water pipe and a circulating pump are disassembled and assembled, and disassembly and assembly of a refrigerant tube are not needed. The air source heat pump water circulation heating and water circulation condensation dehumidification drying device is suitable for drying tobacco, subsidiary agricultural products, food and the like.
