Abstract
An air-conditioning process uses an internally-cooled, liquid-desiccant absorber through which the air to be conditioned, the coolant and the liquid desiccant are passed. The desiccant is passed into the absorber at a flooding rate not exceeding 1.0 gpm/ft.sup.2. Preferably cooling water (as coolant) is passed into the absorber at a flooding rate not exceeding 1.0 gpm/ft.sup.2 and, in that case, cooling air is passed through the absorber in intimate contact with the cooling water to promote evaporative cooling of the cooling water.
Claims10
An air-conditioning process using an internally-cooled, liquid-desiccant absorber through which the air to be conditioned, the coolant and the liquid desiccant are passed, comprising the step of passing the desiccant into the absorber at a flooding rate of 0.03-1.0 gpm/ft while passing the air to be conditioned into the absorber at a flow rate not exceeding 800 fpm.
An air-conditioning process using an internally-cooled, liquid-desiccant absorber through which the air to be conditioned, the cooling water, the cooling air and the liquid desiccant are passed, comprising the step of passing the desiccant into the absorber at a flooding rate of 0.03-1.0 gpm/ft.sup.2 while passing the air to be conditioned into the absorber at a flow rate not exceeding 800 fpm, passing the cooling water into the absorber at a flooding rate of 0.1-1.0 gpm/ft.sup.2, and passing cooling air through the absorber in intimate contact with the cooling water and at a flow rate not exceeding 800 fpm to promote evaporative cooling of the cooling water.
An air-conditioning process using an internally-cooled, liquid-desiccant absorber through which the air to be conditioned, the coolant and the liquid desiccant are passed, comprising the step of passing the desiccant and the air to be conditioned into the absorber at a liquid-to-gas mass flow ratio (liquid desiccant-to-air to be conditioned) of about 0.005-0.17.
