EVALUATION OF DYNAMIC CARACTERISTICS OF GAS COOLER OF THE CARBON DIOXIDE HEAT PUMP ÎN THE TRANSCRITICAL CYCLE

Abstract

Dynamic characteristics of heat pump gas cooler obtained by means of the solution of the dynamics equations in partial derivatives are examined. Control system of the heat pump used for the heating of the heating–system water, supplied from CHP to the district heating system is examined. Possibility of PID-controller with gain scheduling utilization with the coefficients changing depending on gas cooler mode of operation for temperature disturbances compensation of direct heating–system water is shown.
