Air processing unit and control method thereof

Abstract

The invention relates to an air processing unit which comprises a constant temperature and constant humidity assembly and a fresh air bypass assembly. The constant temperature and constant humidity assembly comprises a first shell, a first air mixing channel, a surface air cooler, a second air mixing channel, a heating device, a humidifying device and an air delivery channel. The first air mixing channel, the surface air cooler, the second air mixing channel, the heating device, the humidifying device and the air delivery channel are sequentially arranged in the first shell. The fresh air bypass assembly comprises a second shell and a fresh air channel. The fresh air channel is arranged in the second shell. The air processing unit further comprises a fresh air valve enabling the first air mixing channel and the fresh air channel to be communicated or not communicated, and further comprises an air mixing valve enabling the second air mixing channel and the fresh air channel to be communicated or not communicated. The invention further relates to a control method of the air processing unit, The air processing unit has the advantages that the energy-saving and high-efficiency effects of the whole system are achieved through heat and humidity recycling of fresh air, and the air processing unit has the advantages of being capable of saving energy, environmentally friendly, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an air handling unit and a control method thereof. Background technique [0002] The air handling unit is a unit that can provide a suitable and comfortable environment according to the market demand, and its demand is not only the traditional filtration and refrigeration. According to different occasions, customers may need to add different functions, such as filtration, cooling and heating, noise reduction, humidification, dehumidification, heating, sterilization, heat recovery, constant temperature and humidity, constant temperature dehumidification, cleaning and other functional combinations. In the environment with high precision requirements, the constant temperature and humidity system plays a more important role. Since the unit needs to remove the moisture in the air to meet the customer's requirements, the temperature in the air needs to be removed to remove the moisture in the air. Reduce the water vapor precipitatio...
