Absorption refrigerator driven by waste heat can realize the energy savings. But if only waste heat is used as a heat source, the surplus of the waste heat or the shortage of the cooling capacity occur due to the change of the cooling capacity or the waste heat. In these cases, it is effective to back up this refrigerator with that driven by the stable source such as motive power. But using two refrigerators costs too much. This research suggests the WMVR hybrid refrigerator which can be operated using motive power and waste heat simultaneously. For this refrigerator, the simulation model was constructed and detailed characteristics were clarified. And based on these results, the effect of the design parameters such as the solution concentration and the pressure in the MVR generator on COP was revealed.
