Energy-saving Supporting Tourism Sustainability: A Case Study of Hotel Swimming Pool Heat Pump

Based on energy-relatedmeasurements,this articleevaluates the thermalperformance, energy-saving, indirect emissions and financial feasibilityof using heat pumps for hotel out-door swimming pools in subtropical climates. A rooftop pool of a city-centre hotel was investigated. It was found that the average coefficient of performance (COP) was around 2.0. The measured electricity consumption was 2...

Performance Study and Energy Saving Mechanism Analysis of an Absorption/mechanical Hybrid Heat Pump Cycle

A hybrid heat pump cycle of the heat amplifier type integrating a booster compressor between the generator and the condenser for distributed heating is simulated and analyzed. The interrelation between the two sub-cycles and the hybridization principle are explored. The theoretical analysis is demonstrated by a H2O/LiBr based hybrid cycle simulation. Investigation of the interaction mechanisms ...

Study on Energy-Saving Performance of a Novel CO2 Heat Pump with Applications in Dairy Processes

In dairy processes, there are significant simultaneous heating and cooling demands. A novel type of transcritical CO2 heat pump system is proposed, and its features and benefits are introduced. Based on the technical characteristics, primary energy-savings, and operating cost aspects, the CO2 heat pump system is simulated and compared to current heating and cooling systems used in dairy plants....
