Cooling medium circulation systems for supplying a cooling medium through a single header to multiplexed heat exchangers are described. In an aspect, a system includes, but is not limited to, a storage tank configured to hold a cooling medium in a fluid state; first and second circulation pumps fluidically coupled to the storage tank; a single cooling medium header fluidically coupled with each of the circulation pumps; a first dryer module configured to direct a first portion of cooling medium from the single cooling medium header past a first stream of compressed air and to direct the first portion of cooling medium back to the storage tank; and a second dryer module fluidically configured to direct a second portion of cooling medium from the single cooling medium header past a second stream of compressed air.

The multiple panel heat exchanger includes two or more heat exchange panels arranged side-by-side series with their major cross-sectional areas normal to airflow across the heat exchanger. The heat exchange panels are fluidically connected in series and with a first heat exchange panel in the series having a heat exchange fluid inlet into the heat exchanger and a last heat exchange panel in the series having a heat exchange fluid outlet from the heat exchanger. An inlet liquid refrigerant injector and vaporizer has a valve that can control the rate of injection and can close completely. The panels are connected by a pipe assembly containing another valve that can also control the rate of gas refrigerant passage and which can also be closed.

A heat dissipation device for a vehicle battery includes a box for receiving therein at least a vehicle battery; an upper lid disposed above the box and separated from the box by a waterproof plastic sheet; a microspray heat dissipation pipe disposed on a side of the box and having at least a microspray nozzle in communication with an inside of the box; and at least a non-return exhaust duct disposed on an opposing side of the box and in communication with the inside of the box.

A heat exchanger comprises a stack of sets of fins and tubes attached to or encompassed by embossed plates comprising a void. In some embodiments, the fins overlap the void having a peripheral margin of the fin attached to the peripheral margin around the void. In some embodiments, the fins comprise through fluid apertures allowing lateral fluid flow. In some embodiments, the plates comprise lateral peripheral protrusions enabling selective sealing of gaps between adjacent stacked plates by unselective application of heat or adhesive to a face of the heat exchanger. In some embodiments, the plates comprise uniformizing protrusions in a fluid inlet and/or outlet zone that reduce the amount of non-uniform fluid mass flow between different channel protrusions of heat exchanging zones of the set. Also disclosed are methods for assembly and selective sealing of the heat exchanger and an apparatus comprising the same.

Methods and control systems are disclosed for operating a liquid desiccant air-conditioning system to efficiently maintain a target temperature and humidity level in a space.

A liquid desiccant air-conditioning system provides a uniform liquid desiccant flow distribution and wetting out of membranes used in the membrane-modules of the system.

Liquid desiccant air conditioning methods and systems are operable in multiple modes to efficiently treat air streams provided to a space.

A head condenser is provided with a plate heat exchanger which has first and second channels through which media can flow and which, for the first medium, form tubes between individual plates that are connected to each other to form a pair of plates and, for the second medium, form waves between pairs of plates that are connected to each other to form a stack of plates. A condenser housing is provided in which the plate heat exchanger is arranged, wherein the condenser housing provides pressure chambers which extend over the large outer surfaces of the plate heat exchanger and are in fluidic connection with the channels for the first or second medium. The pressure chambers are traversed by fluid lines which are in fluidic connection with the respectively other first or second medium.

A gas cooler effectively prevents or suppresses an outflow of drain water to the outside. The gas cooler includes a casing, a cooling unit, a seal plate, a lead-in port, a lead-out port, and a drain scattering prevention member. The cooling unit is accommodated within the casing and cools gas. The seal plate is provided in the cooling unit and partitions an inside of the casing into an upper space thorough which the gas before passing through the cooling unit flows and a bottom space through which the gas after passing through the cooling unit flows. The gas is led from the lead-in port into the upper space, and the gas is led out of the bottom space via the lead-out port. The drain scattering prevention member is disposed in the bottom space, and collects the drain water, while allowing the gas to pass therethrough.

An atmospheric water generation system includes a refrigeration assembly, a coolant reservoir, and an atmospheric water generator assembly in fluid communication with the coolant reservoir. The AWG includes an inlet for receiving ambient air and a plurality of tubing members each of which is in fluid communication with coolant generated by the coolant reservoir. The AWG includes a storage container commonly displaced from the plurality of tubing numbers and is configured to receive condensation that falls from the tubing members. Further, the AWG includes a plurality of photon diverters each positioned adjacent a downstream end of respective tubing member for recycling used coolant and directing a plurality of photons generated inside respective tubing members as a result of the condensation process.
