Title:
AIR CONDITIONING DEVICE, AND DESIGN METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/083679
Kind Code:
A1
Abstract:
An air conditioning device (100) according to the present invention is provided with: a refrigerant circulation circuit in which refrigerant piping (4) is used to connect a compressor (10), a heat-source-side heat exchanger (12), throttle devices (26), and refrigerant-side passages of inter-heating-medium heat exchangers (25), and in which a refrigerant is made to circulate; and a heating-medium circulation circuit in which heating-medium conveyance piping (5) is used to connect pumps (31), usage-side heat exchangers (35), and heating-medium-side passages of the inter-heating-medium heat exchangers (25), and in which a heating medium is made to circulate. The plurality of inter-heating-medium heat exchangers (25) are operated using a total heating operation mode in which all of the inter-heating-medium heat exchangers (25) function as condensers, a total cooling operation mode in which all of the inter-heating-medium heat exchangers (25) function as evaporators, and a cooling/heating-operation mixed-operation mode in which one of the inter-heating-medium heat exchangers (25) functions as a condenser, and one of the inter-heating-medium heat exchangers (25) functions as an evaporator. The inside diameter of the heating-medium conveyance piping (5) is set on the basis of the capacity of the usage-side heat exchangers (35) connected by the heating-medium conveyance piping (5).
