Abstract
A liquid glycol enhanced with a polymer-salt solution such as a desiccant in an air pre-conditioner system with a heat-pipe having its heat absorber section in an outside air inlet duct following water vapor adsorption into the desiccant by a contacter section of a dehumidifier, the heat-pipe having its heat rejecter section in an exhaust air duct and preferably preceeding water vapor discharge from the desiccant by a regenerater section of the dehumidifier, a desuperheater for efficient refrigerant compression, a reflux boiler for desiccant regeneration, and a glycol interchanger recovery system for desiccant recovery.
Claims27
An air dehumidifying desiccant recovery system having an outside air inlet duct, a conditioned air supply duct into a conditioned space, a return air duct from said conditioned space and a relief exhaust air duct exhausting return air displaced by outside air and with blower means to transport said outside, supply, return and relief air, and including;
- a heat-pipe means having a heat absorber section in the inlet duct and forming a contacter to remove the heat of adsorption by dehumidifying the inlet air, and a heat rejecter section in the relief exhaust air duct for discharging heat into exhaust relief air flow therethrough,
- a water adsorptive liquid glycol base desiccant and spray bar means applying the same to the heat absorber section-contacter of the heat-pipe means for interface contact with incoming outside air to absorb water vapor therefrom,
- and desiccant regenerater means external of said air ducts and receiving weakened liquid glycol desiccant from said heat absorber section-contacter of the heat-pipe means, and comprised of a heat source means applying heat to the weakened liquid glycol base desiccant to remove water therefrom and discharge said water.
An air dehumidifying desiccant recovery system having an outside air inlet duct, a conditioned air supply duct into a conditioned space, a return air duct from said conditioned space and a relief exhaust air duct exhausting return air displaced by outside air and with blower means to transport said outside, supply, return and relief air, and including;
- a heat-pipe means having a heat absorber section in the inlet duct and forming a contacter to remove the heat of adsorption by dehumidifying the inlet air, and a heat rejecter section in the relief exhaust air duct for discharging heat into exhaust relief air flow therethrough,
- a water adsorptive liquid glycol base desiccant and spray bar means applying the same to the heat absorber section-contacter of the heat-pipe means for interface contact with incoming outside air to absorb water vapor therefrom,
- and desiccant regenerater and glycol recovery means in the relief exhaust air duct, receiving weakened liquid glycol base desiccant from said heat absorber section-contacter of the heat-pipe means, and comprised of a heat source means having means heating the relief air with a water spray bar means applying evaporative water to the heat rejecter section of the heat-pipe means for interface contact with the exhaust flow of relief air to increase the cooling effect of the heat absorber section of the heat-pipe by means of both sensible and evaporative cooling.
