Title:
CONTROL DEVICE, OUTDOOR UNIT, AND AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/193649
Kind Code:
A1
Abstract:
This control device (100) has a timer operation mode which starts an operation of a refrigeration cycle that operates as a hot heat source or a cold heat source earlier, by a preliminary operation time, than a set operation start time of an indoor fan (32). The control device (100) calculates, in the timer operation mode, the thermal capacity of water or brine, calculates the heat storage amount of a second heat medium from the detected temperatures obtained from temperature sensors (25, 26, 34, 35) and the thermal capacity, and determines the preliminary operation time from the heat storage amount. By determining the preliminary operation time as such, a timer operation can be performed so that air having a proper temperature is blown out from an indoor unit (30) at the operation start time of the indoor fan (32) from the very beginning of installation of an air conditioning device (1).
