This paper presents the development of the low cost liquid pump. The rotary compressor developed as the gas compressor for the residential air-conditioner was converted into the liquid refrigerant pump. Problems of the liquid refrigerant pump arethe reliability assessment of sliding parts and the reduction of the noise generated by discharge pulsation in this development. Therefore some modifications, i.e., from the high pressure housing to the low pressure one, and from the compression processwith a discharge valve to the direct discharge compression process, were made. By solving the problems mentioned above, the development of the liquid refrigerant pump using in the ice-storage packaged air-conditioners with the low costs and the high reliability has been achieved.
