A method and apparatus for an inline air purification system is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air. The housing is located in an HVAC duct, and occupies only part of the cross-sectional area of the duct. The remaining area of the duct accommodates bypass air flow to a primary fan in the HVAC system.

An air conditioner includes a control unit that controls an air conditioning operation and controls a maintenance operation to perform maintenance on an indoor unit after the air conditioning operation is stopped, and an operation unit provided for performing a stop operation to stop the maintenance operation. The maintenance operation includes an irradiating operation to irradiate an irradiation area of the indoor unit with ultraviolet rays, and the control unit controls the irradiating operation to continue the irradiating operation even when the stop operation is performed by the operation unit.

Provided is a method for controlling an air conditioner provided with a bipolar ion generation module. The method comprises the following steps: an air conditioner controller determining whether a purification mode control signal for controlling a bipolar ion generation module to start operation is received; if the purification mode control signal is received, the air conditioner controller detecting whether an air conditioner is in a working state; if the air conditioner is in the working state, controlling the bipolar ion generation module to start working; and if the air conditioner is in a standby state, outputting a first drive signal to drive a fan to start operation, and at the same time, controlling a first timer to start timing, and when the timing of the first timer satisfies a first set duration, controlling the bipolar ion generation module to start working. Further disclosed is an air conditioner. According to the present invention, the usage effect of an air conditioner provided with a bipolar ion generation module is optimized in a convenient way.

The invention relates to an apparatus for cleaning a fluid, in particular air, comprising a through-channel for the fluid, a radiation source device and a photocatalysis device, wherein the radiation source device emits electromagnetic radiation, wherein, in order to generate a photocatalytic reaction, the photocatalysis device can be exposed to at least some of the electromagnetic radiation, wherein a sensor device is provided to detect at least one change in radiation parameters of the electromagnetic radiation, wherein a control device is connected to the sensor device via signals, and wherein at least one control parameter of the radiation source device can be modified by means of the control device in the case of a deviation of the radiation parameter from a setpoint/threshold value or setpoint/threshold range.
