Thermodynamic investigations on PDC based solar air conditioning system

Geothermal- And Solar Assisted Air Conditioning System

A research project of the Hamburg University of Technology realizes an open cycle desiccant assisted air conditioning system based on renewable heat sources e.g. solar thermal and heat sinks e.g. shallow geothermal energy. Both advantages of the open cycle process are taken into account, the possible use of a heat sink at higher temperatures and the use of low calorific heat. Moreover, the tota...

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Design and Thermodynamic analysis of solar air humidifier

In this paper, the cooling system of the air humidifire, completely powered by solar energy, has been designed and optimized. In the cooling system, instead of conventional compression cooling systems, the ammonia absorption refrigeration system has been used.Its design is done in a way that the performanceof the system has increased remarkably in environments with high temperature. The ammonia...

Temperature Control of Solar Air Conditioning Systems

This thesis investigates the problem of regulating the temperature of a conditioned space using a Solar Assisted Air Conditioning Systems (SAACS) prototype located at Cabo Rojo, Puerto Rico. The SAACS Prototype consists of a 66 flat plate solar collector array with 115.4 m 2 of selective surface area, a 35 kW single-effect lithium-bromide absorption chiller, a 84 kW cooling tower, a 50 kW auxil...
