A zero-dimensional physical model and mathematical model describing the complicated working process of the working fluid in the cylinder are proposed. The R K method is used to calculate the performance parameters of the gas turbine. Based on the formula for calculating the primary energy utilization coefficient PER of the gas-driven heat pump unit, the influence of the heating coefficient, waste heat utilization rate and effective efficiency on PER and the effective way to increase PER are analyzed and pointed out.
