Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/080255
Kind Code:
A1
Abstract:
The present invention is provided with: a coolant circulation circuit that circulates a heat-source-side coolant, and with coolant tubing connects a compressor, a coolant duct switch device, a heat-source-side heat exchanger, a plurality of throttle devices, and a coolant-side duct of a plurality of inter-heat-medium heat exchangers that exchange heat between the heat-source-side coolant and a heat medium differing from said coolant; a heat medium circulation circuit that circulates a heat medium, and with heat medium tubing connects a pump, a plurality of heat medium duct switch devices, a plurality of use-side heat exchangers that operate as indoor units, a plurality of heat medium flow rate adjustment devices, and the heat-medium-side duct of each inter-heat-medium heat exchanger; a temperature detection means that detects the temperature of the heat medium sent from the inter-heat-medium heat exchangers to the use-side heat exchangers and the temperature of the heat medium flowing out from the use-side heat exchangers; an opening control means that adjusts the flow rate of the heating medium at the heat medium flow rate adjustment devices; and a computation means that calculates the use ability of each indoor unit from the pump rotational frequency, the opening of the heat medium flow rate adjustment devices, the temperatures detected by the temperature detection means, and the power consumption of each indoor unit itself, and on the basis of each calculated use ability and the power consumption of the portions common to the indoor units, proportionally divides the power consumption of the portions in common among each of the indoor units.
