“…The facts stated above indicate that energy and the environment are interrelated; therefore, considering environmental aspects in meeting energy requirements is necessary (Nasruddin et al, 2019). An environmentally friendly refrigeration system is one of the solutions offered by researchers as an efficient and high-performance system (Curtis et al 2005;Omer 2008).…”

A simulation approach to heat pump systems is proposed in this paper. The evaluation of working fluids is conducted. Some alternative refrigerants, including R245fa, R32, R1234ze, and R1224yd are investigated. Moreover, the selected refrigerants are used in the simulation. The simulation is conducted using MATLAB software. Subsequently, the system is analyzed in terms of the coefficient of performance (COP) and exergy efficiency. The results indicate that R1224yd is the best refrigerant with regards to safety, environmental impact, and physical properties. Based on the energy and exergy analysis, R1224yd can attain a COP of 6.5 and exergy efficiency of 29.8%.

“…Hot and humid air is one of the reasons excess energy is required to operate the HVAC system [ 1 ] which consumes approximately 20%–40% of the total energy used in a building [ [2] , [3] , [4] ]. Meanwhile, the vapor compression systems designed based on ASHRAE 62 and 90 standards are commonly used in HVAC dehumidifiers [ [5] , [6] , [7] ].…”

Performance of varying speed screw chiller is affected by many uncertainties. High precision prediction of its characteristics can guide the chiller to reach a better performance. This study presents an artificial intelligence model named least square support vector machine (LSSVM) with genetic algorithm (GA). Five parameters are predicted with the model, including COP, discharge pressure, suction temperature, suction pressure and cooling capacity. By comparing the simulation results with the test results, this model shows a high precision ability to predict the performance of the on-site chiller. Additionally, a newly control strategy is introduced to help the chiller with optimizing performance. Cooling capacity and superheat degree are separately used as input to train the model to control openness of EXV. The prediction of this control strategy process shows enough ability to predict openness of EXV. The results can be used to guide the chiller to reach better performances by adjusting the corresponding parameters.
