Heat pump heat exchange device of drying chamber

Abstract

The invention discloses a heat pump heat exchange device of a drying chamber. The device comprises a drying box, an air supply fan, a sensible heat recoverer, an evaporation fan, an evaporator, a condenser and a compressor; an air supply fan is mounted on the side wall of the bottom of the drying box; the air supply fan is in contact with the outside of the drying chamber; the condenser and the compressor are respectively arranged in the drying chamber adjacent to the air supply fan; a partition plate is mounted over the condenser and the air supply fan; and the sensible heat recoverer and theevaporator are obliquely installed at the two sides of the upper portion of the partition plate; the evaporation fan is installed at the bottom of the sensible heat recoverer; one corner of the evaporation fan is fixed to the partition plate; and an air inlet and a control air valve are arranged at the positions, corresponding to the sensible heat recoverer, of the upper portion and the side wallof the drying box correspondingly. According to the drying chamber heat pump heat exchange device, low-temperature damp and hot air in the drying chamber can be recycled, and the air is returned to the drying chamber to be subjected to secondary dehumidification after being subjected to accurate dehumidification through the heat exchange device.

Description

technical field [0001] The invention relates to a heat pump system, in particular to a heat pump heat exchange device for a drying chamber. Background technique [0002] Drying operations are now widely used in industry and agriculture, especially in the agricultural field. The current drying room adopts a variety of drying methods and cannot accurately dehumidify the hot and humid air after heat exchange, and then dehumidify The final hot and dry air is transported to the drying chamber for drying operation. In view of the existing technical defects, it is necessary to propose a new technical solution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat pump heat exchange device for the drying chamber, which can recycle the low-temperature, hot and humid air in the drying chamber, and return it to the drying chamber for secondary dehumidification after being accurately dehumidified by the heat exchange device...
