Abstract: A method and a device for controlling self-cleaning of an air conditioner are provided. The method comprises: acquiring operation duration, operation status parameters and air quality parameters of an air conditioner; determining an equivalent operation duration for the air conditioner according to the operation duration, operation status parameters and air quality parameters of the air conditioner; and controlling the air conditioner to perform self-cleaning when the equivalent operation duration for the air conditioner is greater than a cleaning duration threshold value. The method may prevent a problem of delayed cleaning or premature cleaning of the air conditioner which is caused by pre-estimating a self-cleaning frequency merely according to one variable which is a booting duration.

Abstract: The invention is a separator designed to separate an incoming stream of liquid, gas, and some particulate matter into a separate gas stream, and a separate liquid stream containing the particulate matter. This is achieved through cyclonic action and the use of a float to operate internal valves within the cyclone. The float is mounted on a shaft which is rotated by the motion of the incoming fluid stream and this motion is used to agitate the solids in the liquid so as to prevent the outlet port from becoming jammed. The outlet port also has an auger contained therein that removes particulate matter.

Abstract: Disclosed are coalescer systems for coalescing a liquid phase dispersed in a gas phase. The disclosed systems include a filter element which, when installed in the system, contacts and moves a valve to an open drainage position to permit flow of liquid through the system. In the disclosed systems, the filter element and valve also are configured such that under excess pressure conditions the valve permits the gas phase to bypass filter media of the filter element. In particular, the disclosed coalescer systems may be utilized in a CV system in order to remove oil mist from gas in the CV system.

Abstract: A gas liquid separator system for a hydrogen generating apparatus includes a collection area for collecting liquid from the generated gases. To empty the collection area occasionally so that liquid does not build up and become entrained again in the dried gas, a vent solenoid is provided in communication with the collection area and a pump is used to create a vacuum periodically on the electrolysis cells. Such arrangement is used to open the liquid gas filter and possibly just the sump to atmosphere occasionally and vacuum generated to draw the liquid from the sump back to the electrolysis cells.

Abstract: Apparatus is described for separating particulate material from an airstream established by suction. The apparatus comprises a primary separation chamber (12) in which particles are separated from the airstream therein by centrifugal force, a main particle collecting region (14) into which the particles separated by the primary separation can fall under gravity, and a secondary separation chamber (90) downstream of the primary chamber (12), to which air and particles not separated in the first chamber, pass. An air outlet in the secondary chamber allows air substantially free of particles to exit. An intermediate particle collecting region (22) is associated with the secondary chamber, in which particles collect after separation by centrifugal force from the air flowing through the secondary chamber (90).

The flow restrictor creates a pressure drop sufficient to force the oil to flow from the oil sump through the oil tube to the diesel engine.

Abstract: Two filters provided in an exhaust path of an internal combustion engine are used to simultaneously collect particulate in an exhaust gas and are alternately refreshed. When a refresh timing of the filters comes, a determination is made as to which of the filters has a larger accumulation amount. The plurality of filters are refreshed in an order from the filter determined as having the larger accumulation amount, and variation of accumulation amounts of particulate of the filters is corrected, so that both of the filters are refreshed within a tolerable temperature range.

Abstract: A vacuum cleaner has an electric motor driving an air impeller for creating suction and a pump impeller which is located in the tank and draws liquid material from the bottom of the tank and expels it from the tank. The vacuum cleaner may have an electrical or mechanical shut-off apparatus which turns off the electric motor if the water level in the tank is too high. The shut-off switch may be bypassed by a user to allow the motor to continue driving the pump impeller to remove liquid from the tank.

Abstract: A dust collector system includes a conduit defining an interior volume, having a first open end, and including an air vent. A pressure differential detector includes a first air flow tap, a second air flow tap, and a pressure differential indicator. The first air flow tap is connected to a dust filter unit dirty air plenum. The second air flow tap is connected to the sensor conduit internal volume at a portion above a location corresponding to a level of collected dust to be detected. The pressure differential detector indicates a presence of at least a selected pressure differential between the first and second air flow taps. When a level of dust in the dust collection container reaches a selected level, it will close the sensor conduit first end. When the sensor conduit first end is closed, a pressure within the sensor conduit internal volume will rise towards atmospheric as a result of the air flow through the air vent.
