An air conditioning system including swappable/interchangeable heat exchanger access panels with accessory mounting capabilities is disclosed. The air conditioning system includes a heat exchanger, a drain pan beneath the heat exchanger to collect condensation from the heat exchanger, a bracket with an opening coupled to the heat exchanger, a plurality of interchangeable access panels adapted to be interchangeably mounted to the opening on the bracket, and an accessory coupled to one of the plurality of access panels.

An inline drain sanitizing system, includes: a manifold assembly including an inlet port, an outlet port, and a treatment port, wherein: the inlet port is configured to be couplable to a condensate supply line and receive unsanitized condensate, and the outlet port is configured to be couplable to a condensate drain line and provide sanitized condensate; and a treatment subsystem configured to interface with the treatment port and process the unsanitized condensate to generate the sanitized condensate.

An air conditioner includes a camera to capture an image of a drain pan inside the air conditioner. An air-conditioning management device acquires, from the air conditioner, captured image information indicating an image of the drain pan captured by the air conditioner. The air-conditioning management device compares the captured image information with reference image information indicating a captured image of the drain pan used as a reference to calculate a dirtiness degree. The air-conditioning management device transmits, to a monitoring terminal, information useful for monitoring of the drain pan, such as the capture image information, information indicating the dirtiness degree, and the like.

An air purifying device, system and method for cleaning and infecting a conditioned space or zone. The air purifying system may include a heating, ventilation and air conditioning (HVAC) system with HVAC equipment configured to provide conditioned air to a conditioned space, where the HVAC system also includes a condensate trap configured to collect condensate produced during operation. The air purifying system also including an air purifying device configured to energize the condensate from the condensate trap to generate an aerosol including negative ions, which are combined the conditioned air provided by the HVAC system to the conditioned space.

An imaging target includes a light emitter configured to emit visible light from a surface of the imaging target, and an imaging device captures an image of at least the light emitter of the imaging target and acquires image data including the light emitter.

The present invention provides a liquid level sensor and an automatic calibration process which removes the need for prior manual calibration of the liquid level sensor, as this happens dynamically during installation and use of the pump. Further, by frequently monitoring the calibration of the sensor and correcting for long term drift or contamination on the sensing surface, the reliability of the liquid level sensor is considerably better than those of the prior art. By operating a solid state sensor, there are no moving parts in the liquid level sensor described above.

A panel assembly includes a panel, a panel frame, and an air guide plate. The panel frame is in annular shape and fitted over the panel. The panel frame includes a plurality of air outlets spaced apart from each other and surrounding the panel, and an air baffle rib provided at an appearance surface of the panel frame and located on a side of the air outlets away from the panel. The air guide plate is movably arranged at the air outlets.
