Objective From the requirements of the performance simulating test for environment control and life support system （ECLSS） in manned spacecraft on the ground, based on the influences of test simulation conditions and crew sense on the test, to improve the accuracy for evaluation test. Methods According to previous many ECLSS performance tests on the ground, the influences of simulation condition difference and the in-chamber crew’s sense on evaluation to the ECLSS performance were analyzed and the solution to these influence problems were proposed. Results Due to the improvement of the test simulation conditions and equipment layouts,the simulating environment in the chamber approached the real environment, and crew sense got better, the objectivity and the accuracy for evaluating test results were improved. Conclusion If the problem such as the influence of equipments layout difference in the chamber, simulation environment difference and daily life sense of the crew in the chamber on ECLSS evaluation are solved successfully, the performance simulation test for ECLSS of the spacecraft on the ground will be conducted well, and correct evaluation to ECLSS performance of the spacecraft will be obtained.
