Turbine driven fluid pump - has evaporator mounted refrigerant pump directly driven from turbine shaft

摘要

The refrigerant driven turbine (2) is mounted directly above the evaporator (1) with its axis vertical. The refrigerant pump is mounted directly below the evaporator on the same axis as the turbine. The turbine impeller (30) refrigerant pump impeller (29) and the output drive pulley (10) are all mounted on the same shaft. The pump shaft (31) is encased in a tube (35), passing through the evaporator and located in the evaporator shell. The whole assembly can be dismantled by withdrawing the turbine and the refrigerant pump shaft and impeller from the top of the evaporator.
