Embodiment Construction

[0040]In the following, an embodiment of an air conditioner according to the present invention is described based on the drawings.

(1) Configuration of the Air Conditioner

[0041]FIG. 1 is a schematic configuration view of an air conditioner 1 according to an embodiment of the present invention. The air conditioner 1 is a device that is used to cool and heat a room in a building and the like by performing a vapor compression-type refrigeration cycle operation. The air conditioner 1 mainly includes one outdoor unit 2 as a heat source unit, indoor units 4 and 5 as a plurality (two in the present embodiment) of utilization units connected in parallel thereto, and a liquid refrigerant communication pipe 6 and a gas refrigerant communication pipe 7 as refrigerant communication pipes which interconnect the outdoor unit 2 and the indoor units 4 and 5. In other words, the vapor compression-type refrigerant circuit 10 of the air conditioner 1 in the present embodiment is configured by the inter...

Abstract

An air conditioner includes a pipe volume calculating section and a refrigerant circuit configured by the interconnection of a heat source unit and a utilization unit via a refrigerant communication pipe. The pipe volume calculating section calculates the volume of the refrigerant communication pipe based on an additional charging quantity which is a refrigerant quantity to be additionally charged after the refrigerant circuit is configured by interconnecting the heat source unit and the utilization unit via the refrigerant communication pipe.

Description

TECHNICAL FIELD[0001]The present invention relates to a function to judge the adequacy of the refrigerant quantity in a refrigerant circuit of an air conditioner. More specifically, the present invention relates to a function to judge the adequacy of the refrigerant quantity in a refrigerant circuit of an air conditioner configured by the interconnection of a heat source unit and a utilization unit via a refrigerant communication pipe.BACKGROUND ART[0002]Conventionally, in a separate type air conditioner configured by the interconnection of a heat source unit and a utilization unit via a refrigerant communication pipe, information on the length and the like of the refrigerant communication pipe is input in order to accurately judge the excess or deficiency of the refrigerant quantity in a refrigerant circuit (for example, see Patent Document 1).[0003]<Patent Document 1>[0004]JP-A Publication No. H8-200905DISCLOSURE OF THE INVENTION[0005]However, the above described work to inp...
