NOVELTY - Multi-temperature refrigerator manufacturing includes refrigeration compressor, condenser, gas-liquid separator, condensation evaporator, two throttle valves, evaporators with high and low temperature chamber and two three-way flow distribution valves. The three-way flow distribution valves are provided for adjusting formation of multi-element mixed non-azeotropic refrigerant. The high-pressure exhaust port of the refrigeration compressor is connected with the condenser.    USE - Method for manufacturing multi-temperature refrigerator having variable evaporation temperature (claimed).    ADVANTAGE - The multi-temperature refrigerator manufacturing method conveniently controls and saves energy during the operation.    DETAILED DESCRIPTION - Multi-temperature refrigerator manufacturing includes refrigeration compressor, condenser, gas-liquid separator, condensation evaporator, two throttle valves, evaporators of high and low temperature chamber and two three-way flow distribution valves, where the three-way flow distribution valves are provided for adjusting formation of multi-element mixed non-azeotropic refrigerant. The high-pressure exhaust port of the refrigeration compressor is connected with the condenser. A steamed part of mixed refrigerant in the condenser is condensed to be in gas and liquid phase, which is then passed into the gas-liquid separator. The gas-liquid separator separates gas-phase medium including more low-boiling point refrigerant from a liquid-phase medium and high-boiling point refrigerant. The liquid-phase medium is throttled by the former throttle valve and then enters the high-temperature evaporator completely. The gas-phase medium is condensed by the condensation evaporator to a super-cooled liquid, which is then throttled by the latter throttle valve and enters into the low-temperature evaporator completely. The refrigerants are mixed before the absorbed heat in the condensation evaporator becomes saturated or super-heated gas, which is then passed into an absorption port of the refrigeration compressor.
