The invention relates to commercial refrigeration equipment, namely commercial refrigerating facilities with a built-in refrigerating unit equipped with a liquid cooling condenser. A proposed refrigeration system is made with centralised condensation heat removal. For this purpose, the known system comprising at least one refrigerating device (1) with a refrigerant circulation loop and a condenser unit with a compressor and a condenser of the refrigerating device uses, according to the invention, a liquid condenser located in the refrigerating device and coupled to at least one closed liquid condensation heat removal loop comprising a means of heat-transfer agent circulation in a liquid loop and a means of heat-transfer agent refrigeration (3) coupled by a heat-transfer agent circulation pipeline (12). This liquid condenser is designed as a plate heat exchanger capable to pass the refrigerant and the heat-transfer agent simultaneously. The claimed invention allows to reduce heat emissions into a room, where refrigerating devices of the system are located, the level of noise from refrigerating devices, system operating costs, in particular, costs associated with installation, materials for the system, system maintenance, etc., to simplify system maintenance and operational flexibility for the purposes of refrigeration, and to reduce negative impact of the system operation on the environment.
