    Abstract: Vapor compression air conditioning systems are provided with a flow restrictor for transferring working fluid to and from at least one of the compressor low pressure inlet conduit and compressor high pressure outlet conduit to provide for accurate charge adjustment to achieve predetermined fluid sub-cooling. Pressure and temperature measurements are taken at a condenser fluid outlet conduit and provided to a microcontroller for determining fluid sub-cooling and comparing sub-cooling with a predetermined target sub-cooling. A charge addition or recovery apparatus may include a solenoid valve controlled by the microcontroller to more accurately control the addition or recovery of refrigerant fluid charge.

    Abstract: The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.
