Abstract

The invention relates to an air source heat pump drying system, which belongs to the technical field of drying systems. The invention mainly solves the technical problems of low drying efficiency, large energy consumption, poor drying effect, unreasonable structural design and easy occurrence of moisture return existing in the existing heat pump drying system. The technical solution of the present invention is: an air source heat pump drying system, which includes an indoor cavity, an outdoor upper cavity and an outdoor lower cavity, the indoor cavity is set in a drying room, and the outdoor upper cavity The air source heat pump drying system also includes a compressor, a heating condenser, a heat exhausting condenser, a heat-absorbing evaporator, a dehumidifying evaporator, a condensed water collecting tray and a storage liquid tank. The invention has the advantages of compact structure, high drying efficiency, high product quality, wide application range, modular design, compatibility with auxiliary heat sources, simple operation, reasonable structural design, and no influence of ambient temperature and humidity.

Description

technical field [0001] The invention belongs to the technical field of drying, in particular to an air source heat pump drying system. Background technique [0002] Heat pump technology is becoming increasingly mature and widely used in air conditioning, heating, hot water, heat recovery, and drying industries. [0003] The existing heat pump drying system, such as Chinese patent CN201220359802.8 discloses a heat pump drying system for circulating heat recovery, which consists of a drying chamber, a heat pump host system, a return air fan, a cold air fan, a bypass ventilation valve, a return air pipe, and a cold air pipe and hot air duct. The drying chamber is provided with an operation door, an air outlet and an air inlet. The heat pump host system is composed of a condenser, a first refrigerant pipe, a compressor, a second refrigerant pipe, an evaporator, a third refrigerant pipe, an expansion valve, and a fourth refrigerant in order to form a circulation system. The ai...
