The Ice on coil is ice storage technology where a tube coil is immersed in water. Ice formed out of a tube with a circulation of coolant in the secondary cooling tube generally the ice. The cooling machines at this time has evolved along with advances in technology. Generally, this machines utilizet for preservation of foods, vegetables and fruits. Interest cool water as secondary refrigerant temperature is 0 ° C to measure the ability of a coolant in the engine cool down the room and cold storage box. Performance cooler for cold storage box and the rooms have different values. COP value that all the rooms are larger than the storage box cold due to the labor supplied to the room is bigger than the box of cold storage, the temperature changes in the evaporator also greatly affect the value of COP, the greater the change in enthalpy evaporator, the greater the value of the COP given the machine
