Abstract

The invention relates to an air source heat pump water circulation heat exchange drying system, which consists of two heat pump units with different applications, wherein one heat pump unit is used for making hot water and the other heat pump unit is used for making cold water. A hot water making unit, a hot water tank and a hot water pipeline form a hot water making circulation loop, the hot water tank, a heating heat exchanger, a circulating water pump and the hot water pipeline form a hot water heat exchange circulation loop, the heating heat exchanger transfers the heat of hot water to air to heat the air in a drying room; a cold water making unit, a cold water tank and a cold water pipeline form a cold water making circulation loop, the cold water tank, a dehumidifying heat exchanger, a circulating water pump and the cold water pipeline form a cold water condensation circulation loop, and due to the cold water running in the dehumidifying heat exchanger, wet and hot air in the drying room is condensed into water on the surface of the dehumidifying heat exchanger while meeting the dehumidifying heat exchanger and is discharged out of the drying room. According to the air source heat pump water circulation heat exchange drying system disclosed by the invention, hot air discharged by a refrigerating circulating condenser is guided into a heating circulating evaporator, so that the whole energy efficiency of the system is improved; the drying room provided by the invention has the advantages of remarkable heating and dehumidifying effect, uniform room temperature and excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a closed drying system utilizing heat pump technology. Background technique [0002] Heat pump drying equipment can be divided into three categories: open type, semi-open type and closed type according to the degree of connection between the drying medium and the external environment. Heat pump technology is gradually being applied to drying equipment due to its energy saving and environmental protection characteristics. The traditional heat pump drying equipment only uses the basic performance of the heat pump to convert the heat energy in the air source into hot air at a certain temperature, and then passes the hot air into the drying room to dry items. Although this type of heat pump drying equipment can replace traditional coal heating or electric heating drying equipment, and has made great progress in energy saving and environmental protection, the working process...
