Abstract: A heat exchange device may include a first pipe including a first inlet, a first outlet, and a first sidewall extending therebetween; a second pipe including a second inlet, a second outlet, and a second sidewall extending therebetween; and a plurality of dimples extending between the first sidewall and the second sidewall. The second sidewall may surround and extend about the first sidewall, the first sidewall may define a first fluid passage configured to permit flow of a first fluid, and the second sidewall and the first sidewall may define a second fluid passage configured to permit flow of a second fluid.

Abstract: A separator device for separating coils of a heat exchanger assembly has a top surface opposite a bottom surface, and an inner portion opposite an outer portion. The inner portion and the outer portion extend between the top surface and the bottom surface. The separator device further includes a pair of sides extending between the inner portion and the outer portion, each of the sides defining a concave curve having an apex. A lug is provided to connect the apex of each concave curve. At least one ramp is defined on the top surface and/or the bottom surface, extending from the inner portion toward the lug. The lug is arcuately shaped to project away from the top surface and the bottom surface and is shaped to correspond to a gap between adjacent coils of the heat exchanger assembly.

Abstract: Disclosed is a monitoring and control system for an air source heat pump apparatus having a controller to control at least one operation of the heat pump apparatus, a temperature sensor to detect the temperature in a specified area at, near, and/or around the controller, and an operable component, the system including a control program to: determine the temperature based on the detected temperature of the temperature sensor; determine whether a first condition exists, the first condition including a determination that the controller is powered, but the operable component is not operating; determine whether a second condition exists, the second condition including a determination that the controller is powered, and the operable component is operating; and based at least partially on determinations (a)-(c), determine the ambient temperature at or around the heat pump apparatus.

Abstract: A fitting for a heat pump having at least one heat exchanger includes a first fitting element configured for connection with a tubing portion of the heat exchanger and a second fitting element removably connectable to the first fitting element and configured for connection with a tubing portion of the heat exchanger. A non-conductive element is disposed between at least a portion of the first fitting element and at least a portion of the second fitting element such that, when connected, the non-conducting element deforms between the first fitting element and the second fitting element to electrically isolate the second fitting element from the first fitting element.

Abstract: A swimming pool, Spa or combination of a swimming pool or spa is heated with a heat pump and a heat exchanger. The heat exchanger comprises a water input, a water output, a heating agent input, a heating agent output, an inner coil and an outer coil being disposed about the outer periphery of the inner coil; and a separator device being configured and disposed to separate the coils in order to minimize vibrating and rubbing against each other. The separator device comprises a first separator device portion having two rounded shoulder portions configured to permit the separator device to be rotated into position between the inner coil and the outer coil, a middle portion comprising two substantially C-shaped curves, which substantially C-shaped curves form a dog bone-shape, and a second separator device portion comprising two rounded configured to be turned or twisted upon assembly of the heat exchanger.
