Abstract

The invention provides a closed heat pump drying system, and relates to the technical field of material drying. The system comprises a drying chamber provided with an air inlet and an air return port; the air treatment chamber is communicated with the air inlet and the air return port, the air treatment chamber is provided with a first heat pump subsystem, and the first heat pump subsystem is used for heating and drying air in the air treatment chamber; and an evaporator of the second heat pump subsystem is located in the air treatment chamber, and a condenser of the second heat pump subsystem is located outside the air treatment chamber. According to the closed heat pump drying system provided by the invention, redundant waste heat in the air treatment chamber can be conveniently discharged, dynamic balance of temperature and humidity in the air treatment chamber is favorably maintained, and the working efficiency and performance are improved.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a closed heat pump drying system. Background technique [0002] The heat pump system has significant advantages such as energy saving and environmental protection, so in the field of material drying, the heat pump system has been widely used. [0003] In the closed heat pump drying system, since the heat provided by the condenser is greater than the cooling provided by the evaporator, and there is heat generated by other components, the closed heat pump drying system has the problem of heat and humidity imbalance. The condenser discharges excess waste heat, but this also reduces the performance and efficiency of the system and affects the drying efficiency. Contents of the invention [0004] The invention provides a closed heat pump drying system, which is used to solve the technical problem that the closed heat pump system in the prior art is prone to heat and humidit...
