Coefficient of Performance Optimization of a Single Stage Thermoelectric Cooler

In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, ...

Performance Evaluation of a Two-Stage Compression Heat Pump System With Refrigerant Charge and EEV Opening

Performance evaluation of multi-stage open-loop impedance pump

Background: Impedance pump is a simple valveless pumping mechanism, which transports fluid through the mismatch of impedance in the system. Mismatch in impedance occurs when an asymmetrical periodic excitation is exerted on the elastic tube. Periodic asymmetrical excitation will then produce a unidirectional flow. Considering a multi-stage system with a single and constant power source, it is w...

Performance evaluation of irreversible cascaded refrigeration and heat pump cycles

This communication presents finite time thermodynamic optimization of irreversible cascaded refrigeration and heat pump cycles having source/sink thermal reservoirs of finite heat capacitance. A general expression for the optimum coefficient of performance of the refrigerator/heat pump is derived at minimum power input and given cooling/heating load conditions, respectively. External irreversib...
