Heating capacity and efficiency increasing with ejector assembly in heat pump

In this study, the effect of heating capacity and heating efficiency were investigated with the help of a liquid pump and an ejector added to a conventional condensing heat pump operating according to the inverse Carnot principle commonly used in room heating. Two different systems working with single and double ejectors are modeled in the calculations. With the fluid pump increasing the fluid pressure, the ejector keeps the compressor outlet pressure at the lower levels, thus reducing the compressor's energy consumption compared to the conventional system. Thus, the heating efficiency coefficient is increased, the heating capacity and the efficiency can be increased so that the cost advantage can be realized by using less energy and reducing the size of the device according to the conventional systems.
