DESIGN a solar hybrid air conditioning compressor system

Hybrid Predictive Control of a Solar Air Conditioning Plant

This paper presents a hybrid controller for a solar air conditioning plant, located at the University of Seville, Spain, and used as a benchmark for the HYCON NoE of the EU. The plant uses two sources of energy: solar and gas, plus a set of accumulation tanks and an absorption tower to provide conditioned air to an university building. The hybrid control is based on a model predictive control s...

Hybrid Model Predictive Control of a Solar Air Conditioning Plant

This paper describes the development and experimental validation of a multi-layer hybrid controller for optimizing energy management in a solar air conditioning plant. The hybrid nature of the process is due to its multi-mode structure: the refrigeration circuit can be fed by flat solar collectors, a storage system, by an auxiliary gas heater, or by a combination of them. The selection of the o...

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...

Design and Application Research on Digital Scroll Compressor in Air Conditioning System

Development of a New Energy-efficient Hybrid Solar-assisted Air Conditioning System

The paper aims at developing a hybrid solar-assisted air conditioner system for performance enhancement and energy efficiency improvement. To increase sub-cooling of the refrigerant at partial loads, we propose a new discharge bypass line together with an inline solenoid valve, installed after the compressor to regulate the mass flow rate of the refrigerant vapour passing through a hot water st...
