Aparato de refrigeración y procedimiento para controlar el mismo

摘要

A refrigeration apparatus includes a condensing unit, a flow distributor (15), and an evaporator (13) connected to the condensing unit via the flow distributor (15). A pressure detector (28) is configured to detect condensation pressure of the refrigerant. A calculation unit (23) is configured to calculate a target condensation pressure of refrigerant necessary for the refrigerant to evaporate at a desired evaporation temperature in the evaporator. A controller is configured to control the condensing unit so that the condensation pressure of the refrigerant becomes equal to or more than the target condensation pressure.
