In today's global environment, accelerated life testing is becoming a competitive advantage when time spent from conceptual stage to the final product development needs to be minimized (project costs and development time) in order to be successful. Using accelerated life testing techniques for mechanical and structural applications have strong challenges when defining the loading but also the fatigue life to represent actual field performance. Such common problems as well as some helpful strategies using accelerated life testing are presented for faster planning of accelerated life testing (ALT). Examples from the refrigeration industry are used to demonstrate the utility of this strategy. In conclusion the test and analysis were effectively used to increase the degree of reliability improvements and to reduce the total number of test hours resulting in a shorter design cycle. © 2016 IEEE.

An energy exchanger is provided. The exchanger includes a housing having a front and a back. A plurality of panels forming desiccant channels extend from the front to the back of the housing. Air channels are formed between adjacent panels. The air channels are configured to direct an air stream in a direction from the front of the housing to the back of the housing. A desiccant inlet is provided in flow communication with the desiccant channels. A desiccant outlet is provided in flow communication with the desiccant channels. The desiccant channels are configured to channel desiccant from the desiccant inlet to the desiccant outlet in at least one of a counter-flow or cross-flow direction with respect to the direction of the air stream.

Heat pumps for climates where demand for cooling and heating are unequal and methods of adapting and distributing heat pumps for such climates. Heat pumps include a compressor, compressor motor, variable-speed drive, and controller. In a number of embodiments, non-volatile memory stores sets of constant speeds for cooling and heating, and a person can select, via an input device, different sets of speeds for cooling and heating to provide the different cooling and heating capacities. The controller then operates the unit at the selected speeds, selecting from within the set based on demand for cooling or heating. In some embodiments, different sets of speeds may have the same minimum speed but different maximum speeds. Identical heat pumps can be configured to have different capacity ratings and different advertized efficiencies for different climates.

Embodiments of the present disclosure provide a system and method for providing conditioned air to at least one enclosed structure. The system may include at least one conditioning module configured to provide conditioned air to the at least one enclosed structure. The conditioning module(s) may include a conditioning energy exchanger. The conditioning module(s) is configured to circulate desiccant through a desiccant circuit to condition air passing through the conditioning energy exchanger. The conditioning module(s) may be configured to receive at least one of concentrated desiccant or diluted desiccant in order to vary temperature or concentration of the desiccant circulating through the desiccant circuit.
