N2 - Exergoenvironmental analysis is used to assess system performance from an environmental point of view. The analyses' guiding principles are formed based on evaluations of the thermodynamic and ambient conditions. The ground source heat pump is one of the most suitable technologies for renewable energy due to its high-performance factor and low-temperature heat energy. In this research, EES software simulated a heat pump with an intermediate economizer and the ground source energy drive. Then the effect of changing different parameters, including the pressure of different parts of the cycle, degree of superheating at the evaporator outlet and degree of subcooling at the condenser outlet, on the environmental parameters (exergoenvironment factor, Exergy stability factor, Environmental damage effectiveness factor, and Exergoenvironmental impact improvement factor), is checked for five working fluids including R134a, R12, R152a, R1234yf and R1234ze(E).
