Heat pump clothes drying system and method for drying clothes

Abstract

The invention relates to a heat pump clothes drying system and a clothes drying method thereof. The heat pump clothes drying system comprises a heat pump evaporator unit, a heat pump compression condensing unit and a drying chamber. A refrigerant loop of the heat pump evaporator unit is connected with a refrigerant loop of the heat pump compression condensing unit through a refrigerant pipe. An air path outlet of the heat pump evaporator unit is connected with an air path inlet of the heat pump compression condensing unit through a pipeline, an air valve A and an air valve C are sequentially disposed on the pipeline in parallel, and an air valve B is disposed on the pipeline between the air valve A and the air valve C. An air path outlet of the heat pump compression condensing unit is connected with an air path inlet of the drying chamber. An air path outlet of the drying chamber is connected with an air path inlet of the heat pump evaporator unit through a pipeline, an air valve F and an air valve D are sequentially disposed on the pipeline in parallel, and an air valve E is disposed on the pipeline between the air valve F and the air valve D. By the heat pump clothes drying system, clothes drying quality is guaranteed while energy consumption is reduced maximally, and drying speed is increased.

Description

technical field [0001] The invention belongs to the technical field of industrial energy saving, and in particular relates to a heat pump clothes drying system and a method for drying clothes thereof. Background technique [0002] At present, people's quality of life is gradually improving, coupled with the requirements of some special links in production and life, centralized washing and drying has become an inevitable trend. At present, the main application equipment in drying clothes is a steam or electric dryer. This kind of equipment has a small stand-alone capacity and high energy consumption. [0003] A heat pump is a highly efficient heating device. The heat pump drying device is an organic combination of heat pump and dryer. In a heat pump drying unit, the exhaust air from the dryer is no longer discharged into the environment, but into the heat pump. The heat pump cools and dehumidifies the exhaust gas discharged from the dryer, then heats it up and enters the ...

AI Technical Summary

Problems solved by technology

[0008] On the premise of ensuring the drying quality of clothes, the present invention proposes a heat pump clothes drying system and a method for drying clothes based on the principle of reducing energy consumption to the greatest extent and improving drying speed, which solves the problem of existing heat pump drying. Dry machine design is unreasonable, energy utilization rate is low, and energy consumption is relatively high
