Problems solved by technology

In the traditional heat pump drying unit, most of them use the method of dehumidification, which loses a lot of high-grade heat energy, wastes energy, is not conducive to energy saving and environmental protection, and cannot accurately control the humidity in the drying room. Relative humidity
In the dehumidification heat pump unit, most of them adopt the closed dehumidification method. Due to the large difference in the operating conditions of the evaporator and the condenser, in the actual operation of the unit, the compression ratio is large, the exhaust temperature is high, and the heating energy efficiency ratio of the equipment is low. Poor dehumidification effect and poor dehumidification reliability

Abstract

The invention discloses heat pump drying equipment, and a dehumidifying control method and a dehumidifying control device thereof. The drying equipment comprises a first evaporator and a dehumidifyingmodule connected with the first evaporator. The dehumidifying module is used for carrying out condensing and dehumidifying on air flowing out of an air returning opening of a drying room, the dehumidifying module exchanges heat with the first evaporator, and the dehumidifying effect of the dehumidifying module on the air can be ensured. On the original basis of the heat pump drying equipment, thedehumidifying module is added, the air in the drying room is dehumidified, the equipment is high in heat energy efficiency ratio, good in dehumidifying effect and high in dehumidifying reliability, meanwhile, the heat pump drying device can intelligently adjust the drying room humidity load and the water inlet and outlet temperature according to the current material and the drying stage where thematerial is located, and the wet load and the actual capacity are dynamically matched.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular, to a heat pump drying equipment, a dehumidification control method and a dehumidification control device thereof. Background technique [0002] As an emerging drying method, heat pump drying has the advantages of energy saving, environmental protection, intelligent control, and good drying effect, and has been widely promoted. [0003] In the heat pump drying project, according to the different ways of processing the hot and humid air in the drying room, it can be divided into a dehumidification type heat pump and a dehumidification type heat pump. In the traditional heat pump drying unit, most of them use the method of dehumidification, which loses a lot of high-grade heat energy, wastes energy, is not conducive to energy saving and environmental protection, and cannot accurately control the humidity in the drying room. Relative humidity. In the dehumidification heat pu...
