Abstract: A dynamic receiver is included in parallel to an expander of a heating, ventilation, air conditioning, and refrigeration (HVACR) system. The dynamic receiver allows control of the refrigerant charge of the HVACR system to respond to different operating conditions. The dynamic receiver can be filled or emptied in response to the subcooling observed in the HVACR system compared to desired subcooling for various operating modes. The HVACR system can include a line directly conveying working fluid from compressor discharge to the dynamic receiver to allow emptying of the dynamic receiver to be assisted by injection of the compressor discharge.

Abstract: A ventilation system for a building in some cases includes a main HVAC blower for moving temperature-conditioned air through the building plus a smaller ventilation blower for providing fresh air. A controller regulates the ventilation blower's speed to provide a target ventilation flow rate regardless of changes in the pressure differential between the indoor and outdoor air. To ensure that the target rate is appropriate for a particular building, the target flow rate is determined based on a ventilation setting that reflects a specified number of bedrooms and a specified amount of floor space of the building.

Abstract: A method of converting a refrigerant includes recovering a refrigerant from a refrigeration unit with an evacuation pump and containing the recovered refrigerant in a container. The method also includes testing the recovered refrigerant and converting the recovered refrigerant. The converted refrigerant is different from the recovered refrigerant. A system for converting a refrigerant includes an evacuation pump, a container, and one or more refrigerant containers. The evacuation pump and container are configured to recover a refrigerant from a refrigeration unit. The one or more containers deliver one or more refrigerant components into the container to convert the recovered refrigerant.

Abstract: Oleophobic and/or philic surface(s) are utilized for oil separation, direction, and/or collection in a refrigeration system. Surfaces of component(s) of a refrigeration system (compressor, oil separator, evaporator, etc.) are produced to be oleophobic or philic. The oleophobic and/or philic surfaces are utilized to direct a flow path of oil within the refrigeration system or to prevent oil connection in an area. Refrigerant phobic and/or lubricant phobic material(s) also may be utilized to help promote separation of refrigerant vapor from refrigerant liquid and/or from oil in refrigeration systems.

Abstract: There is disclosed a refrigeration apparatus comprising a refrigerant circuit, the refrigerant circuit comprising a compressor comprising a compressor fan and a motor to drive the compressor fan; a condensing device disposed downstream of the compressor, the condensing device comprising a condenser and a sub-cooler; an expansion valve disposed downstream of the condensing device; an evaporator disposed between the expansion valve and the compressor; and a main refrigerant line fluidically connecting, in a loop in series: the compressor, condensing device, expansion valve and evaporator. A motor cooling line comprising a motor cooling valve fluidically connects the sub-cooler to the motor to tap refrigerant from the main refrigerant line to cool the motor and is further connected to the main refrigerant line at a return point which is upstream of the compressor fan to return refrigerant to the main refrigerant line at the compressor fan. A bypass line fluidically connects an outlet of the condenser to the expansion valve to bypass the sub-cooler, wherein the bypass line comprises a bypass valve to selectively permit refrigerant in the main refrigerant line to bypass the sub-cooler.

Abstract: A data system controller can include one or more application modules configured to receive data from one or more devices, and a data service module in operative communication with the one or more application modules to provide data thereto. The data service module can be configured to receive data from the one or more devices. The data service module can be configured to update data from a respective device of the one or more devices when a data change probability of the respective device is above a probability threshold to provide updated data from the respective device to the one or more application modules.

Abstract: A pressure pulsation trap is provided. The pressure pulsation trap includes a channel extending from an inlet to an outlet, and a plurality of branches extending from the channel, each of the branches having different lengths than one another. The different lengths are configured such that the branches attenuate noise and/or vibration over a range of operating frequencies.

Abstract: Disclosed is a hermetic AC electric motor that includes harmonics shunting such that high frequency harmonics are shunted from the AC electric motor without the use of one or more high frequency filters in the associated motor drive. A related method of operating an AC electric motor includes shunting high frequency harmonics to a fluid passing through the AC electric motor. Also disclosed is a simplified variable speed motor drive system which eliminates the need for a filter for removing high frequency harmonics.
