A system for drying first and second enclosures includes first and second drying units, each drying unit including a process air stream moving through a process chamber, a reactivation air stream moving through a reactivation chamber and a rotating desiccant wheel configured such that a process wheel portion is located such that the process air stream moves therethrough, and such that a reactivation wheel portion is located such that the reactivation air stream moves therethrough. The reactivation air stream passes through a heating coil before passing through the reactivation wheel. A liquid heating unit circulates first and second heated liquid flows through the heating coils of the corresponding first and second drying units located respectively to dry the first and second enclosures. A flow control is operative to adjust a volume of the first and second heated liquid flows.

Desiccant drying system

A fluid circulating apparatus for warming or cooling a surface includes a pressurized fluid source operative to circulate fluid through a conduit such that a supply fluid moves from a supply port of the fluid source into a first end of the conduit, through the conduit, and from a second end of the conduit to a return port of the fluid supply. A flow control when in a forward mode directs fluid from the supply port into the first end of the conduit and from the second end of the conduit to the return port, and when in a reverse mode directs fluid from the supply port into the second end of the conduit and from the first end of the conduit to the return port. A mode selector is operative to switch the flow control between forward mode and reverse mode.

Reversing circulation for heating and cooling conduits

A temporary heating apparatus comprises a portable heat exchanger which transfers heat from a hot fluid circulating in a primary circulation loop thereof to a heated liquid circulating in a secondary circulation loop thereof. The heat exchanger is connectable to a hot fluid source such that hot fluid from the hot fluid source circulates through the primary circulation loop. A portable remote heating unit comprises a fluid coil releasably connected by flexible conduits to the secondary circulation loop, and a secondary pump is connected to the flexible conduits and the secondary circulation loop to pump heated liquid through the secondary circulation loop, flexible conduits, and the fluid coil of the remote heating unit. The heat exchanger isolates the heating circuit from the hot fluid source, allowing the use of steam as the hot fluid source, and further allowing high pressures in the heating circuit, such as encountered in tall buildings.

Fluid circulation apparatus for temporary heating

An apparatus for reducing a relative humidity of air inside an enclosed space includes a portable outside air heat exchanger unit having a fan operative to create an air stream by drawing outside air from an intake and discharging the air stream through an outlet inside the enclosed space, and a temperature adjusting element located in the air stream. A heating source supplies heat energy to the temperature adjusting element in response to directions from a heat controller. A humidity sensor is operative to sense the relative humidity of the air in a sensing location and to send a humidity signal to the heat controller to change the amount of heat energy supplied to the temperature adjusting element in response to the humidity signal. HEPA filters and ultra-violet lights can shine on the air stream to kill mold spores and the like.

Method and apparatus for controlling humidity and mold

A method for drying a surface comprises supporting a fabric cover above the surface, and holding side edges of the fabric cover against the surface such that an air channel is formed between the fabric cover and the surface. The air channel has an inlet end and a discharge end, and a pressurized warm air stream having a relative humidity less than an ambient relative humidity is directed into the inlet end of the air channel such that the warm air stream moves through the air channel to the discharge end and out to the atmosphere. An apparatus for practicing the invention provides a plenum along the inlet end with plenum outlets to discharge the warm air stream, and cover supports extending out from the plenum to support the cover above the surface. A fabric tube plenum and cover supports provide versatility and portability.

Apparatus for drying ground

A portable apparatus for temporarily warming a plurality of vehicle engines includes a warm fluid circulation loop; an engine fluid circulation loop; a fluid heater; a fluid to fluid heat exchangers; a warm fluid pump; and an engine fluid pump. The warm fluid circulation loop connects the warm fluid heater to the fluid to fluid heat exchanger. The engine fluid circulation loop transfers engine fluid from engine fluid systems to the fluid to fluid heat exchanger. The fluid heater heats the fluid in the warm fluid circulation loop and the warm fluid is then circulated through the warm fluid circulation loop to the fluid to fluid heat exchanger to warm the engine fluid in the engine fluid circulation loop. The warmed engine fluid circulates through the engine fluid system warming the vehicle engine. The apparatus is configured to warm a plurality of vehicle engines at the same time.
