The steam consumption in Hotel New Otani is so massive in conjunction with its characteristic applications, including supplies to the hot water, cooking, linen, space heating and humidifying facilities that a proportionate amount of high-pressure steam has been generated by boiler and the cooling operation has been made mainly by absorption refrigerator. The recent electric rate structure presents a wide variety of choice, and an appropriate use of its system may well lead to energy-saving advantages and furthermore to the effective reduction of burdens for environmental protection. Under these circumstances, therefore, we are sure that there will be more utilization of motor-driven refrigerators in hotels where there is a great demand for heat generation. In this report we verify practical effectiveness of the steam absorption refrigerator and the motor-driven screw chilling unit when they are actually put into operation respectively, and describe the selection of a heat source which contributes to reduction of greenhouse effect gases. We also report our efforts to enhance further effects of screw chilling units.
