Patent ID: 7370485

Claim:
An apparatus for testing a condenser, an expansion device and an evaporator of a refrigeration cycle, comprising: a refrigerant pipe disposed such that the condenser, the expansion device and the evaporator are sequentially positioned from one end thereof to the other end thereof; a refrigerant heating unit installed at one end of the refrigerant pipe which heats a refrigerant and transmits the heated refrigerant to the other end of the refrigerant pipe; cooling fluids respectively provided outside of the condenser and the evaporator which exchange heat respectively with the refrigerant in the condenser and the evaporator; a flow rate measurement unit which measures the flow rate of the refrigerant flowing within the refrigerant pipe; and a temperature and pressure measurement unit which measures variations in temperature and pressure of the refrigerant passing through the condenser, the expansion device and the evaporator, wherein the refrigerant heating unit comprises: a refrigerant tank, connected to an end of the refrigerant pipe, for containing the refrigerant therein; a water tank, surrounding the refrigerant tank, for containing water therein; and an electric heater, installed outside of the water tank, for heating the water in the water tank.
