Abstract: A building chiller/heat pump system includes a chiller/heat pump system for supplying a conditioned fluid to change a temperature of air being delivered into a building. The chiller/heat pump system is provided with a control to achieve a desired setpoint of the air delivered into the building. The control is programmed to receive a prediction of expected remission levels in energy that will be delivered to power the chiller/heat pump system. The control is programmed to change the setpoint such that an energy level required to operate the chiller/heat pump system to achieve the setpoint will drop when the expected emissions level increases, and adjusts the setpoint in an opposed direction when the expected emissions drops. A method is also disclosed.

Abstract: A Stirling refrigeration system is disclosed that comprises a Stirling unit having a hot end and a cold end. In addition, the Stirling refrigeration system includes a hot heat exchanger fluidically coupled to the hot end and configured to release the heat form the hot end, wherein the hot heat exchanger and the hot end define a hot circuit for a first refrigerant to flow therein. Further, the Stirling refrigeration system includes a cold heat exchanger fluidically coupled to the cold end and configured to remove the heat from the cold end, wherein the cold heat exchanger and the cold end define a cold circuit for a second refrigerant to flow therein. One of the first refrigerant and the second refrigerant comprises a two-phase low GWP refrigerant.

Abstract: Disclosed herein is a method and a data processing system for environment evaluation, and a computer-readable storage medium with a computer program for executing the aforementioned method stored thereon. A data processing system according to one aspect comprises: at least one processor; at least one memory; and a computer program stored on the memory and executable on the processor, wherein execution of the computer program on the processor results in the following operations: obtaining user evaluations of an environment and environmental parameter measurements from a plurality of mobile devices; and generating evaluation information about the environment from the user evaluations and the environmental parameter measurements.
