PURPOSE: An energy saving refrigerating machine using waste heat of discharge gas is provided to cool and heat cooling water and defrost water using cold air and hot air of liquid refrigerant and refrigerant gas. CONSTITUTION: An energy saving refrigerating machine using waste heat of discharge gas comprises a cooling water heat exchanger(8), a cooling water circulating pump(9), a defrost water heat exchanger(11), a defrost water circulating pump(12), a defrost water tank(10), a defrost water supplying pump(13), first and second solenoid valves(14,15) for controlling cooling water, and first and second solenoid valves(16,17) for controlling defrost water. The cooling water heat exchanger cools cooling water within a cooling water tank. The cooling water circulating pump forcefully circulates the cooling water within the cooling water tank. The defrost water heat exchanger heats defrost water within the defrost water tank. The defrost water circulating pump forcefully circulates the defrost water within the defrost water tank. The defrost water supplying pump forcefully circulates the defrost water using an evaporator. The first and second solenoid valves for controlling cooling water and defrost water circulate the cooling water and defrost water forcefully transferred to the evaporator. |
