摘要：The Government of Indonesia has done some efforts to overcome energy crisis nationwide. Among them by issuing a policy as the Foundation for the development and improvement of the capacity of providing energy. The Government has issued a presidential instruction number 10 of the year 2005 on energy savings and last Presidential Instruction No. 2 of the year 2008 about saving energy and water. One of the implementation efforts of this energy crisis is overcome with effort saves energy consumption on the air conditioning with develop hybrids air conditioning, namely as the air conditioner at the same time to the water heating. This research is a new technology for energy saving of electricity. The purpose of this research is to produce a prototype of a hybrid energy efficient refrigeration machine that can be function simultaneously as the engine room air conditioner at the same time water heaters. Specific research targets to be achieved is the realization of a prototype of a hybrid air conditioning engine capacity 1.5 PK which can save energy around 60%. The method of research is the planning, creation, testing the performance of air conditioning machines of compression cycle steam hybrid.
