CENTRIFUGAL TURBO FREEZER WITH DEVICE PREVENTING STOP AT LOW PRESSURE

摘要

PURPOSE: A centrifugal turbo freezer with device preventing stop at low pressure is provided to make the turbo freezer continuously work without stop due to pressure of an evaporator. CONSTITUTION: A pressure sensor(7) is installed on an evaporator and connected with a CPU(Central Processing Unit). A free rotation vane is connected with the CPU(8), installed between a compressor(1) and a condenser(2) and actuated according to signal of the pressure sensor to control pressure in an evaporator(5). Excessive pressure in the evaporator is prevented to make a freezer continuously work. Cold water is continuously generated thereby.
