Air source heat pump drying system

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 easiness in moisture regain phenomenon of the existing heat pump drying systems. The technical solution of the invention is that an air source heat pump drying system comprises an indoor cavity body, an outdoor upper cavity body and an outdoor lower cavity body; the indoor cavity body is arranged in a drying room, and the outdoor upper cavity body and the outdoor lower cavity body are both arranged outside the drying room; the air source heat pump drying system further comprises a compressor, a heating condenser, a heat removal condenser, a heat absorbing evaporator, a dehumidifying evaporator, a condensed water collecting disc and a liquid storage tank. The air source heat pump drying system has the advantages of compact structure, high drying efficiency, high finished product quality, wide application range, modularized design, compatibility for auxiliary heat sources, simple operation, reasonable structural design, no influence from environment temperature and humidity, and the like.

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...
