A system and method for estimating the state of charge, i.e., the amount of cooling remaining, in a latent heat thermal storage module of a local environmental control system. The local environmental control system stores cooling energy at night by freezing a latent heat phase change material (PCM), and then releasing the stored cooling energy by removing heat from room air flowing through the PCM during the day. Differential temperature sensors are used measure the air temperature drop across the latent thermals storage unit and the fan voltage, which is directly related to fan air flow rate, is sampled. A controller is programmed to determine the charging state from these measurements.

Cooling charge determination for a local thermal management system

A combined power and refrigeration cascade system that includes an electric power system (PS) that produces both electric power and medium-to-high-grade waste heat. To reduce energy consumption by a load having a computer chip, the load is powered by a power source and thermally coupled to a refrigeration system, which is also powered by the power source. The refrigeration system is thermally coupled to an absorption system, which is configured to remove heat rejected by the refrigeration system. The refrigeration system and the absorption system are in a cascaded arrangement such that the refrigeration system condensing temperature is less than twenty degrees Celsius. In particular, absorption chillers of the absorption system and vapor-compressors of the refrigeration system are in a cascading arrangement that produces subzero cooling.

The present invention relates to a flame-assisted fuel cell (FFC) and, more particularly, to the integration of a FFC in a fuel fired furnace or boiler to enable the generation of both electricity and heat from the fuel's chemical energy, transforming the furnace/boiler into a Combined Heating and Power (CHP) system.

A discharge collector and diffuser for a screw compressor, including a housing having an inlet for receiving flow from a compressor and an outlet and defining therebetween a collector portion, a transition portion and a diffuser portion, the collector portion being adapted to receive a plurality of non-parallel streams from a compressor and to guide the streams into a substantially parallel flow direction, the housing further having a splitter plate positioned in the collector portion to separate the non-parallel streams from each other, whereby the streams are maintained separate until they are substantially parallel, thereby reducing flow losses.

Discharge diffuser for screw compressor

A screw compressor includes a housing containing at least one rotor for generating a discharge flow in a discharge flow direction; a diffuser communicated with the housing and having a collecting portion for receiving the discharge flow, a diffuser throat and a diffuser portion, said diffuser extending from the housing in a diffuser direction; and at least one turning vane positioned in the collecting portion and adapted to guide flow from the discharge flow direction to the diffuser direction.

A scroll compressor assembly incorporates a separator plate which has a clearance between its outer periphery and an inner periphery of an end cap. In this way, the location of the separator plate along the center axis of the scroll can be adjusted. Further, the separator plate is placed on the center shell prior to attachment of the end cap. Thus, the separator plate need not be welded to the end cap as in the prior art. Problems such as weld splatter thus eliminated.
