Abstract: A refrigeration system and method includes a refrigeration component and an electronics module preconfigured with a data set for the refrigeration component. The electronics module stores the data set including identification and configuration parameters of the refrigeration component. A refrigeration system controller that communicates with the electronics module to copy the data set and to regulate operation of the refrigeration component within the refrigeration system.

Abstract: A method and apparatus for refrigeration system control includes a control system operable to meet cooling demand and control suction pressure for a plurality of refrigeration circuits each including a variable valve and an expansion valve. The controller controls the variable valve independently of the expansion valves to meet cooling demand by determining a change in a measured parameter and controlling at least one of the variable valves based upon the change to an approximately fully open position.

Abstract: A solar collector for integral attachment to framing members of a structure comprising a base panel attached to and extending between an adjacent pair of the framing members. The collector includes collector plate which comprises an inlet and an outlet end, a web with opposite side margins and a tubular fluid conduit terminating and open at the collector plate ends. Attachment means is provided for slidably retaining the collector plate to the base panel whereby relative movement therebetween is allowed in response to thermal expansion and contraction of the collector plate. A transparent cover is attached to the framing members and positioned in spaced relation outwardly of the collector plate.
