First experimental investigations of a facade-integrated adsorption system for solar cooling
Abstract
In this work, a novel facade-integrated adsorption system for solar cooling is investigated experimentally with a first prototype. This system consists of an evaporator, which is installed as cooling ceiling, a condenser and an adsorber. To precisely measure the achieved cooling power rates, the system is tested with an almost adiabatic test chamber, which is placed in an air-conditioned laboratory, and the evaporator is installed as cooling ceiling into the chamber. The adsorber are designed as panel-shaped elements and are mounted in standard facade frames on load cells in the laboratory. The adsorber is regenerated by an infrared heater. The first experimental tests reveal minimum evaporator temperatures of around 6 °C and the outer bottom of the evaporator can be maintained below 10 °C for over 15 hours.
