Description

technical field [0001] The invention relates to a rotary dehumidification device and its use method, in particular to a multi-stage rotary dehumidification device with auxiliary heat removal and its use method. Background technique [0002] As a new type of air conditioning system, the temperature and humidity independent control air conditioning system adjusts the humidity by sending dry air to bear the indoor humidity load, and uses high temperature (16-18°C) refrigerant (cold water or refrigerant) Waiting to adjust the indoor temperature, this method can not only better realize the adjustment of indoor temperature and humidity, but also can achieve a good energy saving effect. In the air-conditioning system with independent control of temperature and humidity, it is of great significance to select an appropriate humidity treatment method to improve the energy efficiency of the entire air-conditioning system. [0003] Compared with the condensation dehumidification method...

Problems solved by technology

This way of setting the two-stage condensers 101, 102 helps to discharge the heat of condensation better, but the complexity of the device is increased due to the two-stage air duct for adjusting the air volume of the regeneration air, and the single-stage rotor treatment method It still makes the heat pump work under a large temperature difference, which affects the energy efficiency level of the device

[0005] From the above background technology, there is no heat pump-driven dehumidification air treatment device with auxiliary heat removal at present. Therefore, a high-temperature cold source that independently controls the temperature and humidity of the air-conditioning system is proposed to pre-cool the fresh air to be treated. , The solid dehumidification air treatment device that uses heat pump circulation heat to meet the regeneration requirements of the runners. The dehumidification runners are set in stages to reduce the regeneration temperature requirements, and the auxiliary cooling device is set to eliminate excess condensation heat. It is suitable for the air conditioning system with independent temperature and humidity control, which can be better Meet the needs of indoor humidity regulation and realize the efficient operation of air handling units
