A detection device such as an electrical circuit is included into the refrigerant system design to provide an indication that pressure relief valve has opened, such that the determination can be made by a refrigerant system control or an operator whether the refrigerant system needs to be recharged and whether it can continue its normal operation, narrow its operational envelope or shut down until the refrigerant charge can be restored.

Abstract: This disclosure is related to software that responds to consumer usage patterns in order to create more ice. The developed software monitors ice dispenses rather they are crushed or cubed. When a threshold of the number of dispenses within the preset time period has been met, the freezer enters a high demand mode. During high demand mode, the freezer is commanded to run at a colder temperature for a preset period of time. The method described in this disclosure includes setting a threshold for the number of dispenses within a time interval and detecting the number of dispenses that are related to a trigger's activation. The method continues with sending a signal when the number of dispenses surpasses the threshold within the time interval and taking a corrective action that increases the production of ice when the signal is received.

Abstract: When an internal temperature of a freezing compartment becomes lower than a lower limit temperature TF(OFF) during R-compartment F-compartment alternate cooling, a request for start of R-individual overcool preventing control is made. Then, the rotational speed of the compressor is decreased by one stage and, subsequently, a three-way valve comes to a “R-side open state”, and thus individual cooling of the refrigerating compartment is executed. Thereafter, after a set time, the rotational speed of the compressor is decreased by one stages. When the refrigerating compartment becomes lower than a lower limit temperature TR(OFF), a request for stop of the R-individual overcool preventing control is made. Then, the process shifts to individual cooling of the freezing compartment and then, after waiting for the freezing compartment to again become lower than the lower limit temperature, the compressor is stopped.

Abstract: Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180° C. and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO2) at a concentration greater than 0.2 wt % and less than 0.4 wt %. A concentration of titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibit unacceptable sag prematurely.
