Abstract
An apparatus for controlling a refrigeration cycle for circulating a refrigerant through a compressor a heat exchanger for condensation a flow rate control valve and a heat exchanger for evaporation connected each other, comprising: a first operation means for changing a heat exchanging capability of said heat exchanger for condensation a second operation means for changing a heat exchanging capability of said heat exchanger for evaporation a means for operating a running capacity for changing a running capacity of said compressor, and a control means for reducing a difference between a running condition on a high pressure side or a low pressure side of said refrigeration cycle and a target, wherein when a difference between a running condition on a high or low pressure side and its target is reduced, the control means bring the running condition closer to the target, minimizes a consumption energy, and bring a temperature difference of a heat exchanging fluid between an inlet and an outlet of the heat exchanger for condensation closer to a target temperature difference.
