Abstract: An electronically switchable, bi-stable two-port valve includes a sleeve, a first pole piece having air flow passages formed therethrough and a first wire-wound coil mounted therein and connected to a source of electrical power, a second pole piece having air flow passages formed therethrough and a second wire-wound coil mounted therein and connected to the source of electrical power, and a permanent magnet defining an armature and movably mounted between the first and second pole pieces. The first pole piece is mounted in a first end of the sleeve and the second pole piece is mounted in a second end of the sleeve.

Abstract: A method of controlling fluid flow through a heating, ventilating, air conditioning, and refrigeration (HVAC-R) system includes measuring temperature and pressure at an outlet of an evaporator of the HVAC-R system, wherein the evaporator is in fluid communication with a compressor, a condenser, an expansion device between the evaporator and the condenser, and a flow control valve between the compressor and the condenser, and measuring a sub-cooling temperature at an outlet of the condenser. The measured evaporator temperature and pressure data is sent to a first superheat processor, and the measured sub-cooling temperature data is send to a second superheat processor. A control signal to the expansion device from the first superheat processor and a control signal to the flow control valve from the second superheat processor are then simultaneously sent.

Abstract: A heating, ventilating, air conditioning, and refrigeration (HVAC-R) system includes an evaporator, a compressor, a condenser, an expansion device between the condenser and the evaporator, a superheat controller between the evaporator and the compressor, and a mass flow meter between the condenser and the expansion device. The superheat controller is configured to measure refrigerant fluid pressure and temperature and calculate superheat therefrom, to receive and analyze a mass flow rate of the refrigerant fluid traveling out of the condenser and measured by the mass flow meter, and further configured to provide a control signal to the expansion device.
