Abstract: A method is provided for controlling electrical load on a power grid from a load facility using demand response. The method includes accessing memory storing computer-readable program code for decision analysis of a specified time interval for a demand-response (DR) event. The method also includes executing the computer-readable program code, via a processor, to cause an apparatus to at least make a decision to participate in or opt out of the DR event. This includes the apparatus receiving values of variables that describe occupancy and usage of the load facility for one or more time intervals. The apparatus applies the values to an algorithm that maps the variables to a decision to participate in or opt out of the DR event for the specified time interval. And the apparatus automatically notifies an operator responsible for the DR event of the decision at least when the decision is to opt out.

Abstract: Methods, systems and apparatuses are described that are directed to on-site recovery and/or repurposing of refrigerant, where an original refrigerant is converted into a refrigerant different from the original refrigerant. The refrigerant different from the original refrigerant can have relatively lower global warming potential (GWP) than the original refrigerant. The recovery and/or repurposing can be implemented for example in a refrigeration circuit, such as for example in general cooling and/or heating applications, which may be embodied in a heating, venting, and air conditioning (HVAC) system and/or unit, in a transport refrigeration system and/or unit, as well as in commercial, residential and/or industrial cooling and/or heating applications.

Abstract: A combination refrigeration displacement and drain device is disclosed that can be mounted within a heat exchanger, such as a shell and tube heat exchanger, which may be used for example as a heat exchanger in a chiller unit, which may be used in an HVAC or refrigeration system. One example of such components can include heat exchangers, such as for example a condenser employing a gravity drain. Advantageously, the combination refrigeration displacement and drain device herein can provide a refrigerant charge reduction for example that is used in the chiller unit, while facilitating drainage out of the heat exchanger. The combination refrigeration displacement and drain device can alleviate the liquid refrigerant accumulation that may normally be necessary to induce flow in a gravity drain design.

Abstract: Methods, systems and apparatuses for mounting a motor rotor to a shaft of a compressor are disclosed. The shaft can include a rib region that is configured to form a press fit or a transition fit with the rotor bore. An end of the shaft can also include a plurality of crenulations that can be expanded outwardly in a radial direction relative to a centerline of the shaft. After the rotor is mounted onto the shaft, the crenulations can be expanded to eliminate the clearance between the shaft and the rotor to form a press fit with the rotor bore.

Abstract: Methods, systems and apparatus that are configured to reduce a temperature change of a cooling fluid at where the CO 2 may have a relatively high specific heat capacity in a gas cooler are provided. Additional cooling fluid can be introduced to where the CO 2 may have a relativelyhigh specific heat capacity to reduce the temperature change of the cooling fluid. By slowing down the temperature change of the cooling fluid at where the CO 2 may have the relatively high specific heat capacity, a temperature differential between the CO 2 and the cooling fluid in the gas cooler can be maintained and/or created, which may help heat exchange between the CO 2 and the cooling fluid.

Abstract: Methods, systems and apparatuses are directed to a capacity modulating assembly configured to distribute two-phase refrigerant mixture to an evaporator of a HVAC system, such as a micro-channel heat exchanger (MCHEX) evaporator. The capacity modulating assembly may include a plurality of expansion devices. During capacity modulation, at least one of the plurality of expansion devices can be closed so that a refrigerant flow rate through the remaining expansion devices can be maintained. The capacity modulating assembly can include a refrigerant outflow port, which may help direct refrigerant out of the heat exchanger. The capacity modulating assembly can be connected with the MCHEX. The plurality of expansion devices can be configured to extend inside a header of the MCHEX to help distribute refrigerant to the micro-channel tubes of the MCHEX.
