Solar Desiccant Cooling System

Solar thermal energy or waste heat can be used to re activate the desiccant.

Solar desiccant cooling system. In response to a recent study the role of the desiccant wheel in a solar. The basic process in providing conditioned air may be described as follows. The thermal wheel is a rotary heat exchanger positioned within the supply and exhaust air streams in order to recover the heat energy and the desiccant wheel works in a similar way. 13 installed a solar assisted desiccant cooling system with a 20 m 2 flat plate sc and a 2 m 3 hot water st.

Solar cooling is a system that converts heat from the sun into cooling that can be used for refrigeration and air conditioning. There are several commercially available systems that blow air through a desiccant impregnated medium for both the dehumidification and the regeneration cycle. Solid desiccant cooling. Moisture content desired in supply air is minimal.

Active solar cooling wherein solar thermal collectors provide input energy for a desiccant cooling system. The solar heat is one way that the regeneration cycle is powered. The main components of a solar assisted desiccant cooling system are shown in the figure on the right. Solar cooling has been a hot topic in particular the solar desiccant cooling system for use in hot and humid regions.

These systems are used in applications where the latent heat load is too high i e. Warm and humid air enters the slowly rotating desiccant wheel and is dehumidified by adsorption of water 1 2. In principle the cop of an open desiccant system is similar to its closed counterpart. Desiccant cooling is an open cycle which uses a desiccant wheel and thermal wheel to achieve both cooling and dehumidification.

Abstract this work concerns an innovative solar assisted desiccant and evaporative cooling dec system for building air conditioning. For example cop of 0 7 was said achievable with a solid desiccant cooling system under normal operating conditions 12. Warm and humid air enters the slowly rotating desiccant wheel and is dehumidified by adsorption of water 1 2. The thermodynamic cycle is first theoretically described and then an example of a real.

Energy is saved by using the desiccant to absorb or adsorb the moisture content instead of mechanical equipment. The main components of a solar assisted desiccant cooling system are shown in the figure below. In this system air to air packaged wet heat exchangers are used to maximize the exploitation of the evaporative cooling potential associated with the exhaust air stream. The basic process in providing conditioned air may be described as follows.
