“…Refrigeration applications consume almost 15% of all electricity generated and air conditioning applications are responsible for 45% of housing and comercial building energy consumption [1]. This electricity is mainly produced by non-renewable sources harmful to the environment [2], while population growth increases world electrical energy demand.…”

Abstract:The aim of this study is to model and investigate the concept of a hybrid ammonia-water absorption chiller. Its particularity is having a compressor that creates an intermediate pressure at the desorber. This modification should increase the flexibility of the machine, allowing the recovery of lower temperature waste heat. A preliminary simulation was based on a single stage commercial 10 kW ammonia-water absorption chiller. An experimental study was completed to validate the numerical model of a traditional single stage absorption chiller. The comparative energy and exergy analysis of the hybrid and traditional absorption chillers was undertaken. Due to the reduction of the waste heat temperature for the hybrid chiller, the exergy efficiency increases by 34%. A 38% reduction of the UA coefficient (the product of overall heat transfer coefficient and heat exchanger area), for the same waste heat temperature and refrigeration power, is shown for the hybrid system compared with the traditional one. The theoretical lower bound of the waste heat temperature to be used to drive a hybrid cycle is 42 °C. An economic analysis shows that a hybrid cycle is initially more expensive but quickly becomes profitable compared to a gas-fired absorption machine.

“…It is reported by the International Institute of Refrigeration (IIR) that 15% of the total global electricity production is currently used for air-conditioning and refrigeration. The energy consumption of air-conditioning processes makes up for about 45% of the total electricity demand of private households and commercial buildings with the need of cooling power increasing continuously [1,2]. The high energy demand of air-conditioning can create problems in the near future as the cost of electricity has already been increasing over the last decades.…”

“…Solar energy is currently a subject of great interest, and refrigeration is a particularly attractive application due to the coincidence of the peak of the cooling demand and the availability of solar radiation. Solar electrical and thermal powered refrigeration systems can be used to produce cooling [23]. The first is a photovoltaic based solar energy system, in which solar energy is initially converted into electrical energy and then utilised for producing the refrigeration, similar to conventional methods.…”
