Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the drying and dehumidification heat pump unit in the prior art only has a temperature raising and dehumidifying mode, and cannot dehumidify materials at low temperature, so as to provide a drying and dehumidifying mode that not only has a temperature raising and dehumidifying mode, but also has a low temperature dehumidification mode. Drying dehumidifier in dehumidification mode

Embodiment 1

[0034] This embodiment provides a drying and dehumidifier, including a compressor 6, an indoor condenser 14, an indoor evaporator 13, and a first throttle valve 8. When the drying and dehumidifier is in the heating and dehumidification mode, the The refrigerant outlet communicates with the refrigerant inlet of the indoor condenser 14, the refrigerant outlet of the indoor condenser communicates with the refrigerant inlet of the first throttle valve 8, and the refrigerant outlet of the first throttle valve 8 communicates with the refrigerant inlet of the first throttle valve 8. The refrigerant inlet of the indoor evaporator 13 is connected, and the refrigerant outlet of the indoor evaporator 13 is connected with the refrigerant inlet of the compressor 6 to form a heating and dehumidification circulation pipeline; it also includes an outdoor heat exchanger 2 and a control system; the When the drying dehumidifier is in the low-temperature dehumidification cycle mode, the refrigeran...

Abstract

The invention provides a drying dehumidifier. The drying dehumidifier comprises a compressor, an indoor condenser, an indoor evaporator, a first throttle valve, an outdoor heat exchanger and a control system among which a high-temperature dehumidifying circulation pipeline and a low-temperature dehumidifying circulation pipeline are formed, a controller controls a coolant to circulate in the corresponding circulation pipelines to realize high-temperature dehumidification or low-temperature dehumidification of materials. The drying dehumidifier overcomes the shortcomings that a drying dehumidifying heat pump unit in the prior art only has a high-temperature dehumidifying mode but cannot realize low-temperature dehumidification of the materials.

Description

technical field [0001] The invention relates to the technical field of material dehydration, in particular to a drying dehumidifier not only having a temperature-rising dehumidification mode but also a low-temperature dehumidification mode. Background technique [0002] The air source heat pump drying technology has the advantages of less energy consumption, less environmental pollution, high drying quality, and wide application range. Its excellent energy-saving effect has been proved by various experimental research institutes at home and abroad. The air energy heat pump drying equipment system has the advantages of power saving, safety, and fast heating speed, especially its thermal efficiency exceeds 300%. It will be the main product in the future drying market under the current situation of general lack of energy in the world. [0003] A very important function of air energy heat pump drying equipment is to dry food, such as dehydrating plant seeds, vegetables and meat....
