METHOD FOR PERFORMING OPEN-LOOP OR CLOSED-LOOP CONTROL OF A PUMP IN THE HEAT-TRANSFER MEDIUM CIRCUIT OF A HEAT PUMP SYSTEM

摘要

The invention relates to a method for performing open-loop or closed-loop control of a pump in the cooling circuit of a heat pump system in a vehicle for influencing the through-flow rate of the volume flow of heat-transfer medium in the cooling circuit of a heat pump condenser or gas cooler, wherein an exchange of heat between the coolant circulating in the coolant circuit and the heat-transfer medium circulating in the heat-transfer medium circuit takes place in the heat pump condenser or gas cooler. According to the invention, during an operating state in which, in the heat pump condenser or gas cooler, the heat of the pressurized coolant circulating in the coolant circuit is output to the heat-transfer medium circulating in the heat-transfer medium circuit, the pump for influencing the through-flow rate of the volume flow in the heat-transfer medium circuit is open-loop or closed-loop controlled as a function of the current temperature of the heat-transfer medium.
