Title (EN) HEAT PUMP HAVING MULTI-STAGE HEAT EXCHANGER
(FR) POMPE A CHALEUR DOTEE D'UN ECHANGEUR THERMIQUE A PLUSIEURS ETAGES
(JA) 多段式熱交換器をもつヒートポンプ
Abstract: front page image
(EN)An air conditioner system is additionally provided with an additional air-cooled condenser (2’) having a smaller gas-pipe section area of up to 70% of that of a normal air-cooled condenser (2) and provided behind this condenser (2), the normal air-cooled condenser (2) and the additional air-cooled condenser (2’) being adjacently provided so that their heat exchanging is simultaneously carried out in the atmosphere of the same temperature. Accordingly, the air-cooled air conditioner can improve a heat pump efficiency and permit an operation with a new substitutional refrigerant gas HFC, especially HFC 134a, as a simple gas.
(FR)L'invention concerne un système de climatisation pourvu d'un condenseur à air (2') présentant une zone de section de conduite de gaz réduite de 70% par rapport à un condenseur à air (2) normal et située derrière ce condenseur à air (2). Le condenseur à air (2) et le condenseur à air (2') sont adjacents de sorte que leurs échanges thermiques soient simultanément effectués dans une atmosphère à la même température. Il découle de ce qui précède que le climatiseur à air peut permettre d'améliorer l'efficacité d'une pompe à chaleur et peut permettre un fonctionnement avec un nouveau gaz frigorigène de substitution HFC, en particulier, le HFC-134a, en tant que gaz simple.
(JA)本空調機のシステムは通常の空冷凝縮器2の後に、この2のガス管の断面積比で70%以下と狭めた追設の空冷凝縮器2'を追設し、その熱交換は通常の空冷凝縮器2と追設の空冷凝縮器2'とを同温の大気で同時に行うように併設する。これにより、本空冷空調機は、ヒートポンプの効率化を向上させると共に、新代替冷媒ガスHFC、特にHFC 134aを単体ガスでの運転が可能となる。
