Abstract
In an air conditioner having at least an indoor unit 9 and an outdoor unit 11 through which a coolant flows, a saturation temperature of the coolant at 50.degree. C. is not less than 2500 kPa, and the indoor heat exchanger in the indoor unit satisfies a relationship of Hi.times.Li/(Di.sup.3 .times.Ni.sup.2).gtoreq.150 and the outdoor heat exchanger in the outdoor unit satisfies a relationship of Ho.times.Lo/(Do.sup.3 .times.No.sup.2).gtoreq. 60.
Claims14
An air conditioner comprising:
- a compressor for compressing a coolant and for discharging said coolant;
- an indoor unit comprising an indoor heat exchanger through which said coolant flows;
- and
- an outdoor unit comprising an outdoor heat exchanger through which said coolant flows,
- wherein a saturation temperature of said coolant at 50.degree. C. is not less than 2500 kPa, and said indoor heat exchanger in said indoor unit satisfies a relationship of Hi.times.Li/(Di3.times.Ni2).gtoreq.150, where Hi is a cooling operation rated output (kw), Li is a total length (mm) of a heat exchanger tube, Di is the outer diameter (mm) of said heat exchanger tube, and Ni is the number of paths of said heat exchanger tube.
