A refrigeration plant comprising an evaporator (5), a compressor (1) connected to the outlet of the evaporator, a condenser (2) connected to the outlet of the compressor (1), a controllable expansion valve (4) connected to the outlet of the condenser (2) and having its outlet connected to the evaporator (5) and a condenser pressure control apparatus (10) is to be improved so that, at the least possible condenser pressure, the degree of opening of the expansion valve lies within the optimum operating range. For this purpose, the condenser pressure is controlled depending on the degree of opening of the expansion valve. Fig. 1
