The utility model provides a water-water type/water-glycol type water source heat pump set performance testing device. A pipeline water adding/dividing wall heat exchange structure is adopted. The device comprises a cooling water system, a refrigerant water system, a pipeline water adding/dividing wall heat exchange system, a heat dissipation system and a glycol solution storage system. The primary test of the test device (at the refrigerant water side) adopts a liquid secondary refrigerant method for test measurement and calculation. The check test (at the cooling water side) adopts a set heat balance method for test measurement and calculation. Performance parameters such as refrigerating capacity, refrigerating power consumption and refrigeration energy efficiency ratio and technical parameters such as important temperature and flow of the water-water type/water-glycol type water source heat pump set can be accurately measured; important means are provided for performance test and development and research of the water-water type/water-glycol type water source heat pump; and the water-water type/water-glycol type water source heat pump set performance testing device has the advantages that the operation is energy-saving, the test result is accurate, and all-weather all-condition test can be met.
