Abstract: A refrigerant system is provided with at least one variable frequency drive. In the past, the variable frequency drives were operable such that the voltage-to-frequency ratio remained constant regardless of operation. The present invention realizes that variations in the voltage-to-frequency ratio may be desirable, and the refrigerant system control drives the motors associated with relevant refrigerant system components to reach an optimum voltage-to-frequency ratios in order to achieve higher efficiency, provide operational safety and prevent nuisance shutdowns.

Abstract: An HVAC & R system controller is provided with time pricing information for electricity and/or natural gas. This pricing information is utilized to determine the most efficient system configuration and operation schedule to achieve desired conditions in an indoor environment. As an example, if electricity prices are high, then the controller might rely on a natural gas powered furnace, rather than on the higher-electricity consuming heat pump. In another example, thermal storage media can be charged during off-peak hours when cost of electricity is low and release its thermal potential during high demand periods.

Abstract: A refrigerant system has at least one unloader valve selectively communicating refrigerant between the compressor compression chambers and a point upstream of the evaporator. When the compressor is run in unloaded mode, partially compressed refrigerant is returned to a point upstream of the evaporator. In an unloaded mode, a higher refrigerant mass flow rate passes through the evaporator, as compared to prior art where the by-passed refrigerant was returned downstream of the evaporator. This increases system efficiency by more effectively returning oil which otherwise might be left in the evaporator back to the compressor. Also, the amount of refrigerant superheat entering the compressor in unloaded operation is reduced as compared to the prior art compressor systems, wherein the by-passed refrigerant is returned directly to the compressor suction line. Reduced refrigerant superheat increases system efficiency, improves motor performance and reduces compressor discharge temperature. Also, by moving the unloader line further away from the compressor, the compressor replacement is simplified as there is no connecting unloader line directly in front of the compressor.
Abstract translation: 制冷剂系统具有至少一个卸载阀，其选择性地将压缩机压缩室之间的制冷剂和蒸发器上游的点连通。 当压缩机以卸载模式运行时，部分压缩的制冷剂返回到蒸发器上游的一个点。 在空载模式中，与现有技术相比，较高的制冷剂质量流量通过蒸发器，其中旁路制冷剂返回到蒸发器的下游。 这可以通过更有效地将返回的油返回到蒸发器中返回压缩机来提高系统效率。 此外，与现有技术的压缩机系统相比，在卸载操作中进入压缩机的制冷剂过热量减少，其中旁路制冷剂直接返回到压缩机吸入管线。 降低制冷剂过热度可提高系统效率，改善电机性能并降低压缩机排放温度。 此外，通过将卸载器线移动离开压缩机，压缩机更换被简化，因为在压缩机前面没有直接卸载线。

Abstract: A refrigerant system with an economizer cycle incorporates a time dependant vapor injection scheme to reduce losses and enhance performance. The benefits of such an approach are particularly pronounced at low pressure ratios typical of air conditioning applications. The injection of refrigerant occurs during a limited time interval and at a particular point of time into a compression cycle. The vapor injection preferably occurs when the compression chamber are sealed (or about to be sealed off) from a suction port and continues until refrigerant pressure in the compression chambers is equal (or about to be equal) to the pressure at the injection line. This communication time constitutes about 35% of time of one revolution. In one embodiment, such time dependence of refrigerant vapor injection is provided by a specific compressor design. In another embodiment, a fast-acting solenoid valve is placed at the vicinity of the injection port to control the initiation and duration of the injection process. The benefits for an unloading scheme are disclosed as well.

Abstract: A scroll compressor includes an Oldham coupling which prevents the orbiting scroll member from rotating when driven by a rotating shaft. The Oldham coupling is formed of titanium or titanium alloy, thus increasing the strength of the Oldham coupling while minimizing its weight. Reduced coupling weight minimizes unnecessary scroll compressor vibration.

Abstract: A refrigerant system is provided with an unloader bypass line to selectively unload the compressor and deliver refrigerant from a partially (or fully) compressed location back to a suction port of the compressor. A section of this unloader bypass line is placed in the path of air having passed over an evaporator and towards an environment to be conditioned. This section of the unloader bypass line would contain refrigerant that is at a higher temperature than the refrigerant, which had been delivered into the evaporator by the main circuit. In this manner, this bypass line section will provide the function of reheating the air above the temperature to which it had been cooled in the evaporator to achieve a desired humidity level. Thus, the reheat function is obtained without requiring a dedicated reheat loop, associated components and additional structure. Also, through the refrigerant temperature reduction, compressor reliability and performance are improved. Furthermore, the flow control device may be of an adjustable type (e.g. modulating or pulsating) to achieve variable sensible heat ratios and to cover a wide range of potential applications. Lastly, the bypass line may have extended heat transfer elements allowing heat transfer enhancement between the air and refrigerant.
