Abstract: A blower and heat exchanger component of a heat pump, includes physically moveable interface blocks located at the corners. The blocks are relocatable to different corner locations on the unit, to allow a same blower/heat exchanger component to adapt to an existing duct being located on either side (e.g., by installing the component rotated within the installation space as appropriate). Active interface block(s) moveable to different corners afford access to power connection and/or data connections and status display features. Blank blocks occupy the corner locations left vacant by relocation of active blocks to the side of the unit serving as the front for a particular installation. The moveable corner blocks afford access to the unit for power and data connection, and status display, irrespective of orientation as installed relative to an existing ducting layout of a building.

Abstract: Embodiments disclosed herein include a heat exchanger comprising a first heat exchanger and a second heat exchanger. The first heat exchanger receives a working fluid in a gaseous state and outputs the working fluid in liquid state. The second heat exchanger further sub cools the working fluid.

Abstract: An electrical interface selectively places a heat pump and a backup temperature control device in alternative electrical communication with a single power feed. A compressor of the heat pump may be in selective electrical communication with the power feed via a normally open relay. Removal of a control voltage results in opening of the normal open relay, and closing of a normally closed relay to place the backup temperature control device in selective electrical communication with the power feed. For a ground source heat pump, a ground loop pump may also be in selective electrical communication with the power feed (e.g., via a normally closed relay).

Abstract: A multi-stacked heat exchanger comprises a first heat exchanger and a second heat exchanger. A first end of the first heat exchanger receives a first fluid in a first conduit flowing in a first direction within a plane. A first end of the second heat exchanger receives the first fluid from the first heat exchanger in a second direction flowing opposite to the first direction within the plane. A flow of a second fluid is communicated through the second heat exchanger and then through the first heat exchanger, in a second direction orthogonal to the first direction. The second fluid is in thermal communication with the first fluid in the second heat exchanger and then in the first heat exchanger. By doubling the flowed first fluid back upon itself, embodiments achieve counterflow between the first fluid and second fluid within a compact space.

Abstract: A blower and heat exchanger component of a heat pump includes a physically moveable service panel. The service panel can slide out on a first side or on a second side opposite to the first side, where an existing air duct connects to a third side that is orthogonal to the first and second sides. This sliding service panel configuration allows a same blower/heat exchanger component to adapt the duct being located on either side of the unit (e.g., by installing the component rotated by 180° within the installation space as appropriate). The service panel can slide out on both sides of the component, thereby affording access for service, irrespective of orientation of the component as installed relative to the duct.

Abstract: An electrical interface selectively places a heat pump and a backup temperature control device in alternative electrical communication with a single power feed, thereby simplifying installation and reducing cost. In particular embodiments, a compressor of the heat pump may be in selective electrical communication with the power feed via a normally closed relay. Removal of a control voltage results in opening of the normal open relay, and closing of a normally closed relay to place the backup temperature control device in selective electrical communication with the power feed. For a ground source heat pump, a ground loop pump may also be in selective electrical communication with the power feed (e.g., via a normally closed relay).

Abstract: Syringe drivers and injector devices are provided. The driver includes a housing including a port communicating with a gas chamber therein and connectable to an external air source, and a cavity that receives a syringe containing an agent. A drive piston within the housing includes a first end disposed adjacent the gas chamber and a second end including a plunger connectable to the syringe. A damping mechanism is provided within that housing that is coupled to the drive piston that includes a damper piston within a damping fluid chamber such that, when the drive piston is advanced by gas delivered into the gas chamber from the external source to deliver the agent from the syringe, damping fluid within the damping fluid chamber flows through an orifice or valve from a first region to the second region, thereby limiting movement of the drive piston.
