Problems solved by technology

This traditional heating method not only pollutes the air, but also wastes energy, which is not conducive to the sustainable development of the national economy.
In addition, most of the high-temperature and high-humidity air in the existing dryer is directly discharged through the air outlet, which leads to serious waste of heat and lack of heat recycling

Abstract

The invention discloses a heat pump drying system comprising a heat pump system. The heat pump system includes a compressor, a four-way valve, an outdoor heat exchanger, an inner evaporator and an inner condenser. A port E of the four-way valve is communicated with an output port of the compressor, and a port F is communicated with an inlet of the inner condenser. A port H of the four-way valve iscommunicated with an input port of the compressor, an outlet of the inner condenser is communicated with the outdoor heat exchanger and an inlet of the inner evaporator, and preset low-temperature air performs heat exchange with the inner evaporator and the inner condenser and then is sent out. A circular air passage loop is formed by a heat pump chamber and a drying chamber, so that recycling ofheat is achieved; at the same time, by setting pre-absorption of heat and preheating functions of a heat pipe, dehumidification and heating effects are enhanced in combination with the inner evaporator and the inner condenser.

Description

technical field [0001] The invention relates to the technical field of heat pump drying systems, in particular to a heat pump drying system. Background technique [0002] Most of the traditional drying techniques in my country use electric heating, coal-fired gas boilers and other heating methods to heat and dry the indoor air and discharge the moisture contained in the material to the outside, while supplementing part of the drying fresh air. This traditional heating method not only pollutes the air, but also wastes energy, which is not conducive to the sustainable development of the national economy. In addition, most of the high-temperature and high-humidity air in the existing dryer is directly discharged through the air outlet, which leads to serious waste of heat and lack of heat recycling. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a heat pump drying system with high heating e...
