Abstract (en)
[origin: GB2474696A] A refrigeration plant has a refrigerator circuit comprising a compressor 10, a condensing coil 14, an expansion valve 20 and an evaporator 18. Heat is absorbed in the evaporator and exhausted at the condenser. Pressure is measured at the compressor inlet and a blower arrangement for blowing cool air over a heat transfer surface of the condenser is controlled in dependence upon the pressure measurement by a controller 16. The controller may be coupled to a transducer 16a to provide a variable output indicative of pressure in the low pressure circuit. A further sensor 16b may also be included to control the blower based on a difference between a determined discharge pressure and a measured discharge pressure, the determined discharge pressure being determined by the fluid pressure at the compressor inlet.
