Abstract:This paper aims for construction of a small, clean air cooling system using a water refrigerant and examines it experimentally. We offer a basic report for realization of the non-Freon air-cooling system using only water as a refrigerant. An experimental device consists of two groups, the first stage is composed a vacuum pump and a vacuum container of about 60 liters in volume, and the second stage has two heat exchangers (the one is heat load) and a water circulation pumps. The temperature characteristics of each place are measured by thermocouples. An air-conditioner indoor unit or a heater for as heat load was used; the air conditioning measurement and the energy were measured, respectively. Consequently, in air-cooling system used only water refrigerant, the ability to cool a room air enough was provided. The development of a new vacuum pump which can exhaust a large amount of water vapor is introduced as an appendix.
