Flat Plate Solar Collector Performance Using Alumina

Displaying solar adsorption refrigeration system powerpoint presentations improving design performance for solar cooling system ppt presentation summary.

Solar adsorption refrigeration system ppt. 12 solar powered adsorption ice maker system. The refrigerant produces cooling effect in the evaporator and releases the heat to the atmosphere via the condenser. Introduction adsorption refrigeration system uses adsorbent beds to adsorb and desorb a refrigerant to obtain cooling effect.

This work presents a solar adsorption refrigeration system using silica gelwater pair. Powerpoint ppt presentation. The refrigerant gets condensed in the condenser and it gets evaporated in the evaporator.

The silica gel water chillers studied can be powered by hot water warmer than 55 0c. Several studies have also been carried out both experimentally and. Wide range of operating tempera tures.

High temperature flat plate concentrating or evacuated tube solar collectors are needed for improved cop. Adsorption refrigeration nominally requires heat of 70 900c. The adsorption refrigeration system has several advantages compared to the absorption refrigeration system.

Cop and refrigeration power of the chiller was 062 and 564 kw respectively. The cycle needs an electrical power. The current technology of adsorption solar powered icemakers allows a daily ice production of between 4 and 7 kg per m2 of solar collector with a solar cop between 010 and 015.

Up to now the production of the cold conditions is undertaking mainly by the classical way of compression refrigerator cycle. Adsorption refrigeration system uses solid adsorbent beds to adsorb and desorb a refrigerant to obtain cooling effect. It has the advantage of total autonomy and continuity in cold production since it offers the possibility to use free renewable energy and causes no environmental effect.

Considering the destruction of the ozone layer caused by the use of cfcs absorption. In the vapor absorption system the refrigerant used is ammonia water or lithium bromide. Graduation project iiredesigning adsorption methanol activated carbon solar cooling system.

Adsorption systems mainly use a natural. Consequently selection and optimization of solar collector is a vital role in the adsorption refrigeration system. These solid adsorbent beds adsorb and desorb a refrigerant vapor in response to changes in the temperature of the adsorbent.
