An improved distribution system for an evaporator. The system comprises an evaporator having a plurality of heat exchange flow paths; and an evaporator distributor operably connecting the plurality of flow paths to an evaporator inlet. The system includes an impingement device having an outlet operably connected to the evaporator inlet and having at least a pair of fluid inlets arranged so that fluid entering through either of the fluid inlets directly impinges upon fluid entering the other fluid inlet thereby providing a churned up fluid to the impingement device outlet. Additionally, the system includes an expansion device having an inlet and an outlet; and a separator having a separator inlet connected to the expansion valve outlet and having at least a pair of outlets. The separator is arranged to divide fluid from the expansion device into several streams and direct those streams to its outlets. The system also includes at least a pair of conduits, each having a first end connected to a separator outlet and a second end connected to an impingement device inlet.

An air inlet and damper arrangement. The arrangement comprises a system housing with an external wall having a fresh air inlet; and an inlet air enclosure located within the system housing adjacent the external wall and arranged about the air inlet. The enclosure has an aperture connecting the interior of the enclosure with the interior of the system housing; and a damper sized to cover the aperture and pivotable within the small enclosure between a position covering the aperture and a position uncovering the aperture.

An apparatus and method for soft-starting a three-phase motor for connection to a three-phase power source for driving a three-phase motor. Soft-start provides a way to reduce the amount of starting torque and current during starting conditions. First, second, and third conductors are connected between a three-phase power source and a three-phase motor. A power contactor interrupts and provides current along the three conductors. A phase-shifting element for shifting the phase of the power signal normally outputted from the first conductor to match the phase of the power signal normally outputted from the third conductor is connected between the first and third conductors. A switching apparatus having first and second switch elements is connected between the phase-shifting element and the third conductor. When the first switch element is closed, current flows from the first conductor to the motor via the phase-shifting element. When the second switch element is open, no current flows from the third conductor to the motor directly.

An air conditioning system. The system comprises an indoor section and an outdoor section arranged in side-by-side arrangement. The indoor section includes an indoor tangential fan having an axis aligned in a first direction, an indoor heat exchange coil, and a supply air aperture which longitudinally extends in the first direction and avoids line of sight noise transmission from the indoor fan. The system includes an axis commonly supporting and operably coupling the indoor fan and the motor, and a scroll housing within the indoor section and arranged about the indoor tangential fan. The indoor tangential fan, motor and axis are assembled to form a first module, the scroll housing forms a second module and the first module is independently removable from the second module without the necessity of disengaging any connection between the first and second modules. The system includes a fan support bracket supporting a first end of the axis, and the motor supporting a second end of the axis. The fan support bracket includes a bearing assembly rotatably supporting the axis and having a flange; a support bracket including a flange support matingly adapted to engage the flange, a clip adapted to engage a lower end of the bearing assembly support, and an axis aperture adapted to receive the first end of the axis.

A refrigeration system with a high percentage of fresh air. The system comprises a supply air duct; an indoor heat exchange coil operably positioned in the supply air duct; a reheat heat exchange coil operably positioned in the supply air duct; an outdoor heat exchange coil; at least one compressor; and an expansion device. The system also comprises refrigeration system tubing connected to and serially arranging the compressor, the outdoor heat exchange coil, the expansion device and the indoor coil into a refrigeration circuit; and reheat tubing connecting the reheat coil to the refrigeration tubing so as to arrange the reheat coil in a parallel circuited arrangement with the outdoor heat exchange coil and in a series circuited arrangement with the compressor, the expansion device and the indoor heat exchange coil. The system further comprises a subcooler located between and operably connected to the indoor heat exchange coil and the parallel circuited arrangement; and a control valve in the reheat tubing operable to control refrigerant flow through the reheat coil.
