In this paper, we analyzed the characteristics of the mass flow rate and velocity of the refrigerant inresponse to a change in the number of holes and the diameter size(Type-1～4) of the valve guide refrigerantto flow from Pc to Ps when the pressure is constant. Type-1 is 40% higher mass flow flowing in the directionof Ps as compared with the Pc mass flow rate. Type-2 is 64% higher mass flow flowing in the direction of Psas compared with the Pc mass flow rate. Type-3 is 50% higher mass flow flowing in the direction of Ps ascompared with the Pc mass flow rate. Type-4 is 47% higher mass flow flowing in the direction of Ps ascompared with the Pc mass flow rate.
