A filter screen rail module, a cleaning member, an indoor unit of an air conditioner, and an air conditioner are provided. The filter screen rail module is applied to the indoor unit of the air conditioner. The indoor unit of the air conditioner includes a face frame defining an air inlet. The filter screen rail module is disposed adjacent to the air inlet. The filter screen rail module is separable from the face frame. The filter screen rail module is provided with a guiding space, in which the filter screen moves.

An elevator ventilation system comprising an ultraviolet source that illuminates elevator system air blown through an illumination chamber, and an air filter that filters the air as it flows through the chamber. The ultraviolet source is blocked from view from outside the illumination chamber. An air curtain emitter may expel a curtain of air across the elevator doorway, limiting air communication between an elevator interior and the elevator landing when elevator doors are open. An air outlet may be shaped to receive an elevator light fixture and to expel air into the elevator interior via an aperture adjacent the light fixture. An air curtain emitter may comprise an air outlet slot shaped to expel a curtain of air separating an interior of the elevator car into at least two air compartments defined by the “barrier” of the air curtain.

To provide a reticular resin molding and an operating method of an air conditioner capable of increasing a heat exchange efficiency in a heat exchanger by controlling a charge of air introduced into the heat exchanger.

The reticular resin molding has a plate form, is composed of a thermoplastic resin, includes a plurality of vent holes penetrating in a thickness direction, and is capable of increasing a heat exchange efficiency in a heat exchanger by introducing air, having passed through the vent holes to control a charge thereof, into the heat exchanger. The reticular resin molding is composed of a thermoplastic resin of polyethylene or polypropylene obtained by dissolving therein a non-fired powder of a montmorillonite-based clay mineral. Further, the operating method of an air conditioner comprises providing, to the heat exchanger, this reticular resin molding so as to cross an airflow path to a heat exchanger, and introducing the air, having passed through the vent holes, into the heat exchanger.

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.
