Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes an array of packaged units; and a controller to obtain an operating condition of the array of packaged units, derive the operating condition to construct an operating pattern, select one or more packaged units to be adjusted to increase efficiency of the array of packaged units based on the operating pattern, and to adjust operation of the one or more packaged units selected by the controller.

Abstract: A refrigeration unit and methods of operating a refrigeration unit for an HVACR system are disclosed. The refrigeration unit includes a refrigerant circuit, including a compressor, a condenser, an expansion device, and an evaporator fluidly connected. The condenser includes a condenser portion and a subcooler portion. A single receiver tank is fluidly connected to an output of the condenser portion and an input of the subcooler portion. A restrictor is fluidly connected to the receiver tank. The restrictor can induce a pressure drop in a working fluid flowing from the subcooler portion.

Abstract: To continue operating a compression refrigerant system even while the system's brazed plate heat exchanger contains, in localized areas, water at or below its atmospheric subfreezing water temperature, a penetrating temperature probe senses the water temperature at a strategic intermediate point between the heat exchanger's water inlet and outlet. The brazed plate heat exchanger comprises a series of corrugated plates stacked and brazed together to create an alternating arrangement of water and refrigerant passages in heat transfer relationship with each other. In some examples, the idea is to take advantage of the principle that water has a lower freezing temperature at relatively high pressure and that the relatively small micro-channel passages of intermediate water passages within the brazed plate heat exchanger can withstand appreciably higher pressure than other areas within the heat exchanger, such as the areas at the heat exchanger's water inlet and water outlet.
Abstract translation: 为了继续操作压缩制冷剂系统，即使系统的钎焊板式热交换器在局部区域中含有等于或低于其大气低温水温的水，穿透温度探针也会感测热交换器的入水口之间的战略中间点处的水温 和出口。 钎焊板式热交换器包括一系列波纹板，堆叠并钎焊在一起，以产生彼此热传导关系的水和制冷剂通道的交替排列。 在一些实例中，这个想法是利用水在较高压力下具有较低的冷冻温度的原理，并且钎焊板式热交换器内的中间水通道的相对较小的微通道通道可以承受比其他的更高的压力 热交换器内的区域，如热交换器的进水口和出水口的区域。

Abstract: Embodiments of a heat exchanger, e.g. a micro-channel heat exchanger are disclosed. The heat exchanger may include a plurality of rows of micro-channel tubes, each of which can be configured to direct a working fluid in a specific direction. The heat exchanger may include one or more distributors in a distribution header of the heat exchanger, each of which can be connected to a different application circuit (e.g. a refrigeration circuit) so that a capacity of the heat exchanger may be regulated. The heat exchanger as disclosed herein can be used as an evaporator and/or a condenser in a refrigeration system.
