【Abstract】 Considering the irregular work schedule of household air conditioning system,according to the theory of regeneration,develops a regenerative household ice storage air conditioning system.Analyses the influence of factors including ice thickness,initial evaporation temperature and hold-over coil diameter on the cold storage process.Tests the performances of the developed air conditioning system on conditions of cold storage mode and refrigeration-cold storage mode,respectively,and compares the test results with those of traditional air conditioning systems.The results show that the regenerator contributes to the solution to anti-frosting and anti-freezing of outside suction tube.The corresponding suction temperature of compressor is increased approximately by 25 ℃, and the evaporating temperature is increased approximately by 3 ℃ by applying regenerator.The resultant COP is improved by 3.6%.The system with refrigeration-cold storage mode solves the problem of unfixed service time for household air conditioning,which plays an important role in peak load shifting strategy.更多还原
