MULTI-CONNECTED SYSTEM AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087700
Kind Code:
A1
Abstract:
A multi-connected system (1000) and a control method thereof. The multi-connected system (1000) comprises a water source device (10), a heat pump unit (30), a water tank (20), and a controller (40). The heat pump unit (30) supplements heat for the water source device (10) by means of the water tank (20). The controller (40) is configured to: when the water source device (10) operates, if a water inlet temperature (Te) at the first water inlet (A1) is less than a first preset temperature, control the heat pump unit (30) to be turned on; and if the water inlet temperature (Te) at the first water inlet (A1) is greater than a second preset temperature, control the heat pump unit (30) to be turned off, the first preset temperature being less than or equal to the second preset temperature. Therefore, a heat supplementing effect of the water source device can be improved, and energy consumption is reduced.
