Title: Refrigeration arrangement and methods for reducing charge migration

Abstract

A refrigerator appliance including a refrigerant circuit between a condenser, an evaporator, and a compressor that includes two conduits and pressure reducing devices arranged in parallel between the evaporator and the condenser. The appliance also includes a valve system to direct refrigerant through one, both or none of the conduits and pressure reducing devices, and a heat exchanging member in thermal contact with either one pressure reducing device, or one conduit between the pressure reducing device and the valve system.

  • A refrigerator appliance including a multi-capacity compressor and a refrigerant circuit with two conduits and pressure reducing devices arranged in parallel between an evaporator and a condenser. Refrigerant can flow through one, both or none of the conduits and pressure reducing devices. The appliance also has a heat exchanger in contact with either one pressure reducing device, or one conduit between the pressure reducing device and the valve system. The appliance also includes a controller for priming the compressor above a nominal capacity for a predetermined or calculated duration at the beginning of an ON-cycle.
  • Disclosed herein is a carburetor comprising a first stage including a vertically extending primary air induction passage including a venturi section and a portion downstream of and below the venturi section, a primary fuel passage communicating with the venturi section of the primary air induction passage and with a fuel source, and a primary throttle valve mounted in the downstream portion of the primary air induction passage for movement between a partially open position and a fully open position. The second stage includes a vertically extending secondary air induction passage including a venturi section and a portion downstream of andmore » below the venturi section, a secondary fuel passage communicating with the venturi section of the secondary air induction passage and with a fuel source, and a secondary throttle valve mounted in the downstream portion of the secondary air induction passage for movement between an open position and a closed position. A fuel or air passage communicates between the primary and secondary air induction passages for draining fuel accumulating in the secondary air induction passage above the secondary throttle valve to the primary air induction passage.« less
  • A method and arrangement are described for containing the core melt flowing from a nuclear reactor into a core catcher below the core wherein the core melt is permitted to gradually penetrate layers of a core catcher materials of inorganic reactor soluble oxides or salts disposed in the core catcher which core catcher materials are dissolved by the oxidic part of the core melt. The molten solution, after solidification and after being cooled down to a temperature at which hydrogen generating reactions do not take place, is leached with water and rinsed out of the core catcher without the needmore » for humans to be present in the reactor containment and to be exposed to radiation.« less
  • This patent describes a method of reducing NO/sub x/ component of flue gas produced in the flame of a coking oven of the type having vertical heating flues cooperating in pairs of flamed and non-flamed flues, the flamed heating flues including inlets for rich gas, primary air and lean gas arranged at the bottom region of the flues to provide a low level combustion stage, and further including inlets for secondary air and secondary lean gas arranged above the low level combustion stage to provide a high level combustion stage, partitions separating the flamed and non-flamed heating flues in respectivemore » pairs having a top opening for recirculating flue gas from the flamed flue to the non-flamed one, and a bottom opening for mixing a branch current of the recirculating flue gas with the supplied primary air and rich and lean gases in the flamed flue. It consists of a. adjusting the recirculation current rate, namely the volume ratio of the recirculated flue gas branch current to the flue gas current without recirculation, to amount between 20% and 50%; b. adjusting the combustion stage ratio, namely the volume ratio of the supplied primary air in the low level combustion stage to the supplied secondary in the high level combustion stage to an amount between 40% and 70%; and c. arranging the high level combustion stage between 35% and 55% of the height of the heating flues.« less
  • A combustion apparatus has a combustion chamber which is divided into combustion zones respectively communicating with individual mixing zones in a mixing chamber. Combustion air enters the mixing zones and then flows into the combustion zones. The concentration of NO /SUB x/ in the combustion products of each of the combustion zones is measured and water vapor is fed into each mixing zone in an amount which depends upon the NO /SUB x/ concentration for the corresponding combustion zone. The amount of water vapor fed into a mixing zone is such as to maintain the combustion temperature below a valuemore » at which substantial quantities of NO /SUB x/ are formed. The water vapor is fed into the mixing zones generally countercurrent to the combustion air entering the combustion zones and the water vapor and combustion air flow into the combustion zones together.« less
