Ejector Air Conditioning

An Ejector Refrigeration Cycle for utilizing Solar Thermal Energy

Getting hot thermal energy from solar energy is popular but cooling with solar thermal energy is not spread so far. It is possible to reduce electricity demand to use solar energy for cooling in summer. We are designing a system of an ejector refrigeration cycle, especially concerning the configuration of ejector itself, which can generate […]


Ejector Based Air Conditioning using Natural Refrigerants

This paper deals with modeling of the ejection cycle, especially for solar air-conditioning. The presented approach for ejector analysis has been proposed, based on formulation of performance curve of the installation and performance curve of an ejector. The operation point of the whole system is found at the interception of these two curves. The exemplary […]


Ejector Air Conditioning and Refrigeration Technology

Ejector or jet pump refrigeration is a thermally driven technology that has been used for cooling applications for many years. In their present state of development they have a much lower COP than vapour compression systems but offer advantages of simplicity and no moving parts. Their greatest advantage is their capability to produce refrigeration using […]


Transcritical Co2 Refrigeration Cycle with Ejector Expansion Device

An ejector expansion transcritical CO2 refrigeration cycle is proposed to improve the COP of the basic transcritical CO2 cycle by reducing the expansion process losses.
