Abstract
An apparatus and method of heat exchange in which a liquified gas is evaporated in a first coil disposed in a fluid heat exchange medium in a heat exchanger, absorbing heat by the evaporating liquid to chill the heat exchange medium, disposing in the heat exchange medium in the heat exchanger a second coil containing heat exchange medium in fluid connection with a body of heat exchange medium contained in a reservoir, chilling the heat exchange medium in the heat exchanger and circulating chilled heat exchange medium to the reservoir and from the reservoir to a facility location needing cooling, returning warmed heat exchange medium from the facility location to the reservoir and thence to the second coil for rechilling and reuse.
