Summary

The fourth report of the international panel of climate change states that “There is no doubt of Global Warming”. The average global atmospheric and oceanic temperatures have risen, the amount of ice in both the Arctic and Antarctic as well as on mountains has decreased, the average global sea level has been reported to rise. These are all a clear indications of global warming. In the field of air conditioning and refrigeration, use of natural refrigerants is eagerly anticipated. The authors, therefore, developed a central air-conditioning system using mixed hydrocarbon refrigerants. The unit is composed of a screw compressor with an explosion proof semi-hermetic motor to minimize refrigerant leaks. Tests were carried out in six operation modes with a combination of two sources (air and water) and three supplies (cooling and heating and hot water production). This paper reports on the basic performance tests of the heat pump.
