The major difference between multi heat pumps and conventional heat pumps is the number of indoor units. For multi heat pumps, it is essential to have precise control of cooling capacity distribution to each indoor unit having different cooling load. Through the experiments with various test conditions, it was found that an indoor unit affected another by refrigerant mass flow rates, evaporating pressures and cooling capacities when temperature differences of inlet air between two indoor units were exist.
