A simple, cost effective system and method for flexibly managing heat pump source fluid is disclosed. The source fluid flow-manager significantly enhances heat pump efficiency by selectively coupling it to renewable energy resources via geothermal, solar, and ambient air thermal exchanges. The sophisticated interconnection of these thermal exchanges also reduces installation costs. A preferred embodiment of the source fluid flow-manager consists of three T-port valves, two pumps and a plurality of connection points, and operates in at least twelve modes. These modes selectively interconnect source fluid flow between fluid utilizing units, such as heat pumps, and a variety of thermal exchange and/or storage units, such as hot or cold underground thermal storage-and-exchange regions, dry coolers and solar thermal collectors. The valves and pumps are controlled by a programmed controller, guided by input from flow meters and thermometers. Operational modes are matched to thermal need, and to system and environmental status.

A mobile cooling system comprising a heat exchanger for cooling fluids, configured for efficient and cost-effective transportation without wide-load restrictions over highways. The mobile cooler can include a cooler, a motor capable of operating a fan at variable speeds, a control module and telemetry system for remote operation and monitoring, and a solar panel to provide alternative energy, all mounted on a trailer.

A solar-powered two-bed adsorption chiller which can operate after sunset when the solar radiation intensity becomes zero. Rechargeable solar-powered batteries (SPBs) are connected to a flat-plate solar collector (FPSC). The photoelectric charges are directed from FPSC to a solar charge controller (SCC) which acts as a charge amplifier thus magnifying the total charge before it is finally collected inside the SPB for future use. The SPB is in turn connected to a resistance heating wire (RHW) which is immersed inside the HWST.
