Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0030] figure 1 The schematic diagram of the system during the humidity adjustment process of the pre-cooling wheel is shown. The device includes a water-cooled chiller unit, an air-cooled heat pump unit, a sensible heat recovery unit, a rotary solid adsorption dehumidification equipment and an electric heater. The summer fresh air passes through the water-cooled chiller fan coil unit 1, The evaporator 2 of the air-cooled heat pump unit, the evaporator 3 of the sensible heat recovery unit, and the dehumidification area of ​​the rotary solid adsorption dehumidification equipment 4 are sent into the room, and the return air passes through the condenser 5 of the sensible heat recovery unit in the process of being processed. , the electric heater 6 and the regeneration zone of the rotary solid adsorption dehumidification equipment 4 are discharged outside.

Abstract

The invention discloses a pre-cooling type rotating wheel humidity adjusting fresh air processing device. The fresh air processing device comprises a water cooling type water chilling unit, an air-cooled heat pump type unit, a sensible heat recovery unit and a rotating wheel type solid adsorption dehumidification device which are sequentially arranged; and the water cooling type water chilling unit comprises a water cooling type water chilling unit evaporator, a water cooling type water chilling unit compressor, a water cooling type water chilling unit condenser, a water cooling type water chilling unit throttle valve, a water cooling type water chilling unit fan coil and a cooling tower which are sequentially connected in the circulation direction of a refrigerant, wherein the water cooling type water chilling unit fan coil is connected to the chilled water outlet end and the chilled water inlet end of the water cooling type water chilling unit evaporator, and the cooling tower is connected to the cooling water outlet end and the cooling water inlet end of the water cooling type water chilling unit condenser. According to the fresh air processing device, regeneration air is preheated by utilizing discharged heat of the condenser in summer, so that the energy consumption caused by regenerated heat provided by an electric heater is reduced or avoided; and humidification air is pre-cooled by utilizing absorbed heat of the evaporator in winter, so that a return air cooling device is removed, and the energy efficiency of the fresh air processing device is improved.

Description

technical field [0001] The invention belongs to the field of heating, ventilating and air-conditioning systems, and relates to a fresh air processing device for adjusting humidity with a rotary wheel. Background technique [0002] In the air conditioning system, according to the requirements of the current national health standards, a certain amount of fresh outdoor fresh air needs to be supplied to the room. Due to the temperature, humidity and dust content, the outdoor fresh air usually cannot be directly sent into the room, and must be subjected to heat and humidity treatment. During the cooling season, the outdoor air is usually high temperature and high humidity, and it is necessary to cool and dehumidify the outdoor air, especially in the humid areas in the southeast. The core task of the air treatment process is to dehumidify the fresh air. At present, the air-conditioning system in my country generally adopts the condensation dehumidification method, that is, the ch...
