    • A performance testing apparatus includes a refrigerant pipe provided with open ends, and installed such that a condenser, an expansion device and an evaporator are sequentially aligned from one end thereof to the other end thereof. A refrigerant heating unit is installed at one end of the refrigerant pipe for heating a refrigerant by a double boiler method and transmitting the heated refrigerant to the other end of the refrigerant pipe. Cooling fluids are respectively provided outside of the condenser and the evaporator for exchanging heat with the refrigerants in the condenser and the evaporator. A flow rate measurement unit is used for measuring the flow rate of the refrigerant flowing within the refrigerant pipe. A temperature and pressure measurement unit measure variations in temperature and pressure of the refrigerant passing through the condenser, the expansion device and the evaporator.
    • 性能测试装置包括设置有开口端的制冷剂​​管,并且安装成使得冷凝器,膨胀装置和蒸发器从其一端依次对准到另一端。 制冷剂加热单元安装在用于通过双锅炉方法加热制冷剂的制冷剂管的一端,并将加热的制冷剂传递到制冷剂管的另一端。 冷却流体分别设置在冷凝器和蒸发器的外部,用于与冷凝器和蒸发器中的制冷剂进行热交换。 流量测量单元用于测量在制冷剂管内流动的制冷剂的流量。 温度和压力测量单元测量通过冷凝器,膨胀装置和蒸发器的制冷剂的温度和压力变化。
