摘要： A furnace assembly comprising a non-condensing furnace with a draft inducer. The draft inducer includes a permanent magnet electrically commutated motor and a draft inducer blower fan. The motor includes a stator, a rotor, a motor cooling fan, and a controller. The rotor being rotatable relative to the stator, the fan being operatively coupled to the rotor such that rotation of the rotor causes rotation of the fan, the controller being configured to selectively operate the motor in first and second different torque ranges of the rotor, with the first and second torque range operating within a fixed percentage and within a fixed percentage of each other. The controller being configured such during normal operation, the motor is not operable at any torques between the first torque range and the second torque range except during transitionary periods.

摘要： An energy recovery apparatus for use in a refrigeration system, comprises an intake port, a nozzle, a turbine and a discharge port. The intake port is adapted to be in fluid communication with a condenser of a refrigeration system. The nozzle comprises a fluid passageway. The nozzle is configured to expand refrigerant discharged from the condenser and increase velocity of the refrigerant as it passes through the fluid passageway. The turbine is positioned relative to the nozzle and configured to be driven by refrigerant discharged from the fluid passageway. The discharge port is downstream of the turbine and is configured to be in fluid communication with an evaporator of the refrigeration system.

摘要： An energy recovery apparatus for use in a refrigeration system, comprises an intake port, a nozzle, a turbine and a discharge port. The intake port is adapted to be in fluid communication with a refrigerant cooler of a refrigeration system. The nozzle comprises a fluid passageway. The nozzle is configured to reduce temperature and pressure of refrigerant discharged from the refrigerant cooler and increase velocity of the refrigerant as it passes through the fluid passageway. The turbine is positioned relative to the nozzle and configured to be driven by refrigerant discharged from the fluid passageway. The discharge port is downstream of the turbine and is configured to be in fluid communication with an evaporator of the refrigeration system.
