Problems solved by technology

[0002] In order to increase the dehumidification capacity after the treated space of the conventional dehumidification heat pump drying system passes through the evaporator, the air volume is often reduced, and then through the condenser, the temperature difference of the treated air will be large and the flow rate will be small, making the condensation temperature very high, thus cooling Cycle efficiency is low

Abstract

The embodiment of the invention provides an efficient heat pump drying system and relates to the field of heat pump drying. The efficient heat pump drying system comprises an air return air flue, a first blowing air flue, a second blowing air flue, a compressor, a first heat exchanger, a second heat exchanger and a throttling structure. The first heat exchanger comprises a first heat exchange partlocated in the first blowing air flue and a second heat exchange part located in the second blowing air flue, the first heat exchange part is connected to the second heat exchange part, an inlet of the first heat exchanger is formed in the first heat exchange part, and an outlet of the first heat exchanger is formed in the second heat exchange part. The second heat exchanger is mounted in the first blowing air flue and enables air to pass the first heat exchange part and the second heat exchange part successively. The compressor is connected to the first heat exchanger, the first heat exchanger is connected to the throttling structure, the throttling structure is connected to the second heat exchanger, and the second heat exchanger is connected to the compressor. According to the embodiment of the invention, efficiency of heat pump drying can be improved.

Description

technical field [0001] The invention relates to the field of heat pump drying, in particular to a high-efficiency heat pump drying system. Background technique [0002] In order to increase the dehumidification capacity, the treated space of the conventional dehumidification-type heat pump drying system often reduces the air volume after passing through the evaporator, and then passes through the condenser, which will cause the temperature difference of the treated air to be large and the flow rate to be small, making the condensation temperature very high, thus cooling Cycle efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency heat pump drying system, which can improve the efficiency of the heat pump drying system. [0004] Embodiments of the present invention are achieved like this: [0005] An embodiment of the present invention provides a high-efficiency heat pump drying system, including a return ...
