Abstract: A heating, ventilating, and air conditioning (HVAC) system includes a refrigerant loop having a compressor, where the compressor is configured to circulate a refrigerant through the refrigerant loop, a first heat exchanger disposed along the refrigerant loop, where the first heat exchanger is configured to place the refrigerant in a first heat exchange relationship with a working fluid, and an air handling unit having a second heat exchanger, where the second heat exchanger is configured to place the working fluid in a second heat exchange relationship with an airflow, and where the air handling unit is isolated from the first heat exchanger to reduce or eliminate mixing of refrigerant with the airflow.

Abstract: An electronic device can be enhanced to enable its user to navigate about and view, on the device's display, different portions of a page or document while the device remains in a zoomed-in mode that magnifies the portion of the document that the device is currently displaying. Upon entering the zoomed-in mode, the device can magnify a portion of the document on the display. While in this mode, the device can react to user-produced gestures in a manner that is different to the manner in which the device would react to the same gestures otherwise. Responsive to user-produced gestures while in the zoomed-in mode, the device can navigate to other portions of the document while remaining in the zoomed-in mode, so that those other portions are also presented magnified. The device's user is not forced to first zoom-out from one document portion in order to zoom-in on another document portion.
