摘要： An adequate operation and performance of a refrigerant system includes the steps of adding a refrigerant that is different from the original refrigerant, into the refrigerant system should any operational problems be observed during operation of the refrigerant system. As an example, should the refrigerant system be cycling frequently, a lower pressure refrigerant may be added or replace, partially or fully, the refrigerant the system being initially charged with. By making this change, the present invention can, for example, lower the provided system capacity, and hence reduce the amount of cycling. Additionally, conditioned space comfort and system reliability would be improved. Further, changes over time, such as the degradation of the heat exchanger performance, and their negative effect on system operation can be alleviated by such a refrigerant substitution.

摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：制冷剂系统设置有卸载器旁路管线以选择性地卸载压缩机并将制冷剂从部分（或完全）压缩的位置输送回压缩机的吸入口。该卸载器旁路管路的一部分被放置在通过蒸发器并朝向要调节的环境的空气的路径中。卸载器旁路管路的该部分将包含比通过主回路输送到蒸发器中的制冷剂更高的温度的制冷剂。以这种方式，该旁路管路部分将提供将空气重新加热到其在蒸发器中被冷却的温度以达到所需湿度水平的功能。因此，在不需要专用再热循环，相关部件和附加结构的情况下获得再热功能。另外，通过制冷剂的温度降低，可以提高压缩机的可靠性和性能。此外，流量控制装置可以是可调节型（例如调制或脉动），以实现可变的显热比并覆盖广泛的潜在应用。最后，旁路管线可以具有延长的传热元件，从而允许空气和制冷剂之间的热传递增强。
