Heat transfer methods, systems and compositions

Disclosed are refrigerants, and heat transfer compositions, heat transfer systems and heat transfer methods containing such refrigerants, wherein the refrigerant comprises at least about 97% by weight of the following three components (a)-(c) and the following fourth component if present:

Refrigerant, heat transfer compositions, methods, and systems

A sensor package for sensing vibration is described. The sensor package includes a carrier and a piezoelectric module coupled to the carrier. A wireless vibration sensor is further coupled to the carrier at a distance from the piezoelectric module. The sensor package further includes one or more conductive paths coupling the piezoelectric module to the wireless vibration sensor. The sensor package may be disposed on a bearing housing of a rail vehicle. The sensor package may also be utilized in marine, land and aviation applications.

Vibration sensor package

A refrigerant composition, including trifluoroiodomethane (CFI); 1,1,1,2-tetrafluoropropene (HFO-1234); difluoromethane (HFC-32); and carbon dioxide (CO), for use in a heat exchange system, including refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-404A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-404A.

Heat transfer compositions, methods, and systems

Disclosed are refrigeration systems having a heat source to be cooled and a heat sink and a capacity of from about 2 to about 30 tons and comprising: (a) a heat transfer composition comprising a refrigerant comprising at least about 80% by weight of trans1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) or at least about 80% by weight of trans1,3,3,3-tetrafluoropropene (HFO-1234ze(E)); (b) a centrifugal compressor having a discharge:suction pressure ratio at least about 2:1; (c) a condenser operating at temperature in the range of from about 10&#xb0; C. to about 60&#xb0; C.; (d) and expander for producing relatively cold low pressure refrigerant liquid; (e) a high efficiency evaporator; and (f) at least one heat exchanger fluidly connected between said evaporator and said refrigerant suction of said compressor.

High efficiency air conditioning systems and methods

The present invention includes refrigerant composition, including trifluoroiodomethane (CFI); 1,1,1,2-tetrafluoropropene (HFO-1234); difluoromethane (HFC-32); and pentafluoroethane (HFC-125), for use in a heat exchange system, including refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-404A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-404A.

Heat transfer compositions, methods and systems

A rail vehicle includes a rail vehicle frame, a pocket, a first beam, a second beam, an endplate, an actuator and a workhead carrier. The pocket is coupled to a frame portion of the rail vehicle frame. The first beam is disposed in a cavity defined by the pocket. The second beam is disposed proximal to the first beam. The end plate couples the first beam and the second beam. The actuator extends the first and second beams such that the end plate is displaced transversely with respect to the rail vehicle frame. The work head carrier is operable to translate along the first and second beams and couple the second beam to the frame portion.

Workhead assembly

A light reference system includes a first, second and third rail followers. The second rail follower is disposed between the first and third rail followers. First and second light sources are disposed on the first and third rail followers and operable to emit light towards the second rail follower. First and Second imaging devices are disposed on the second rail follower. The first imaging device is operable to receive the light emitted by the first light source and provide first image data. The second imaging device is operable to receive the light emitted by the second light source and provide second image data. A processing device is configured to perform a measurement, based on the first and second image data, indicating a relative position of the second rail follower with respect to at least one of the first and third rail followers.
