Stay first liquid refrigerant on the dividing plate 23 in upper space 21a inside and introduce the lower space 21b of first container 21 by the pressure reduction between above-mentioned upper space 21a and the lower space 21b.When a certain amount of first liquid refrigerant was stored in lower space 21b, controller 65 returned to second container 41 with first liquid refrigerant of first container, 21 lower space 21b inside.
First liquid refrigerant that returns to second container 41 and therefore be stored among second container, the 41 lower space 41b is introduced indoor unit 11 by heating pipe line 47.Then, first liquid refrigerant indoor expansion valve 15 of process and indoor heat converter 13, thus carry out heat exchange, thus the heating clamber inner room.
Introduce the upper space 21a of first container 21 by the outlet side refrigerant line 11a of indoor unit 11 through first gaseous refrigerant of indoor heat converter 13.Then, first gaseous refrigerant cools off, reduces pressure, is condensed into first liquid refrigerant by cooling unit 54, stays then on the dividing plate 23 of first container 21.
As mentioned above, in the present invention, first liquid refrigerant that is stored in first container returns to second container without intermediate receptacle.Therefore, reduced the difference in height between first container and second container, thereby simplified the overall structure of air-conditioning system, be convenient to the system of installing an air-conditioner, and reduce production costs.
And, in the present invention, owing to not only first cold-producing medium is sent back to, therefore compares and more reduced first refrigerant amount that is stored in first container and second container with conventional art by the difference in height between first container and second container but also by the first container median septum.
Because the present invention can implement under the situation that does not break away from spirit of the present invention or essential feature in many ways, it will also be appreciated that the above-mentioned specific embodiment is not limited by any details of aforementioned specification, unless it is dated especially, can very wide in range explanation in the defined spirit and scope of claims, therefore belong to the border of claim and the institute in the scope and change and revise, therefore the equivalent structure of perhaps this border and scope also is contained in the appended claim.
