Experimental study on automotive cooling and heating air conditioning system using CO2 as a refrigerant.
Author(s) : TAMURA T., YAKUMARU Y., NISHIWAKI F.
Summary
This paper presents an experimental study on automotive cooling and heating air-conditioning systems using CO2 as refrigerant. In this study, in order to increase the energy efficiency, the following measures were taken: 1) construction of a CO2 heat pump system that uses the heat release at the dehumidifying condition as the auxiliary heating method; 2) the examination of the optimal method to control the amount of the CO2 refrigerant held under both cooling and heating conditions; 3) improvement of the elemental devices in the CO2 heat pump cycle. As a result, a prototype of CO2 automotive cooling and heating air-conditioning systems for medium-sized cars was successfully developed. With this system, a performance that is better than that of the present HFC-134a system can be achieved.
