Disclosed herein is a method of operating a polymerization reactor for a polymerization reaction comprising modifying a recycle gas composition to increase the heat capacity of the recycle gas wherein the recycle gas composition is modified by reducing or eliminating the nitrogen concentration in the recycle gas. In an embodiment, the nitrogen concentration is reduced or eliminated by reducing or eliminating one or more nitrogen input sources to the polymerization reactor and replacing the nitrogen with an alternate inert fluid (a gas or liquid that is inert to the catalyst and reactants). The alternate inert fluid has a higher heat capacity and a higher molecular weight than nitrogen. In an embodiment, the nitrogen utilized to convey a catalyst into the polymerization reactor is replaced with an alternate inert fluid. In an embodiment, the alternate inert fluid is ethane, propane, isobutane, or combinations thereof.

A semiconductor structure and method of manufacturing that has integrally-formed enhanced thermal management. During operation of a semiconductor device, electron flow between the source and the drain creates localized heat generation. A containment gap is formed by selectively removing a portion of the back side of the semiconductor device substrate directly adjacent to a localized heat generation area. A thermal management material is filled in the containment gap. This thermal management material enhances the thermal management of the semiconductor device by thermally coupling the localized heat generation area to a heat sink. The thermal management material may be a Phase Change Material (PCM) having a heat of fusion effective for absorbing heat generated in the localized heat generation area by the operation of the semiconductor device for reducing a peak operating temperature of the semiconductor device.

The invention belongs to the field of control of air conditioners and relates to an intelligent defrosting control method of a split air conditioner. The method specifically comprises the following steps: a) leading an air conditioner system to enter into the heating operation mode; b) leading the system to record the cumulative operation time of a compressor, detecting and recording the temperature T2 of a coil of a heat exchanger of an indoor unit and the indoor temperature T1, and calculating the difference delta T which is equal to T2-T1; c) entering into the step d when the cumulative operation time of the compressor achieves the set time and the compressor is open currently; and d) dividing into the high wind gear operation state, the medium wind gear operation state, the low wind gear operation state, the gentle wind operation state and the fan stop state according to the operation states of an internal fan; the system takes the operation time of the compressor, the temperature T2 of the coil of the heat exchanger of the indoor unit and the indoor temperature T1 as parameters for setting the conditions of entering into the defrosting operation and exiting the defrosting operation against the different wind gear operation states; and the system carries out defrosting if meeting the conditions of entering into the defrosting operation, and the system exits the defrosting operation and returns to the step a) if meeting the conditions of exiting the defrosting operation. The method is characterized by low cost and high efficiency.
