Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/054154
Kind Code:
A1
Abstract:
An air conditioning device (500) is provided with: a liquid equalization control means (60) which regulates the respective flow rate regulators (8, 108) of outdoor units (51, 151) so that the amount of a discharge refrigerant discharged from the outdoor units (51, 151) to the indoor unit (53a, 53b) side and the amount of an inflowing return refrigerant from the indoor unit (53a, 53b) side are equal to each other; and an injection control means (70) which, while the flow rate regulators (8, 108) are regulated by the liquid equalization control means (60), controls for each of the outdoor units (51, 151) the flow rates of refrigerants flowing into compressors (1, 101) from injection ports, the control being performed on the basis of discharge temperatures (Td1, Td2).
