Description

TECHNICAL FIELD

[0001] The utility model belongs to indoor fresh air treatment technical field, concretely relates to a rotary dehumidifier based on photovoltaic heat recovery. BACKGROUND

[0002] The traditional and commonly used dehumidification method is condensation dehumidification, and the basic principle is to remove the water vapor in the humid air by cooling the humid air to below the dew point temperature. Although this dehumidification method can control humidity to a certain extent, with the continuous reduction of the evaporator surface temperature, frost problem will occur, which will lose dehumidification capacity and affect efficiency. If defrosting is achieved by switching heating, although the problem of frosting can be solved, the dehumidification capacity will be greatly reduced, and it is difficult to stably and reliably meet the dehumidification requirements of different environmental temperatures and high dehumidification scenes.

[0003] The rotary dehumidification technology is a solid adsorption dehumidification technology, and the dehumidification is not limited to 0℃ dew point temperature. Compared with the traditional dehumidification method, low dew point air can be obtained, and the dehumidification of different environmental temperatures and high dehumidification scenes can be more stably and reliably met. When running, the adsorption wheel adsorbs water molecules to reach a saturated state in the treatment air area, and then enters the regeneration area for desorption and regeneration by high-temperature air. The high-temperature air of the conventional rotary dehumidifier is generally heated directly by an electric heater or a condenser, and the energy consumption is relatively large. In addition, for buildings equipped with photovoltaic power generation devices, the photovoltaic components will continuously generate heat during power generation. If the heat is not dissipated in time, it will affect the power generation efficiency of the photovoltaic components, and also increase the thermal load of the building in summer. SUMMARY
