Abstract

The invention relates to an air source heat pump unit including an outdoor unit, an indoor unit, at least two terminal devices and a control module, at least two terminal devices connected to the indoor unit, and the control module can divide the terminal devices into a first group of terminal devices and a control module. The second group of terminal equipment; when the automatic emptying function is turned on, it is emptied according to the emptying cycle cycle. The emptying cycle includes at least two emptying times of the first group of terminal equipment, at least two first group of terminal equipment system waterway stabilization times, At least two second group of terminal equipment system waterway emptying time, at least two second group of terminal equipment system waterway stabilization time. The air source heat pump unit of the present invention includes a complete hot water system air exhaust control, without manual operation, and can completely remove the air in the water system to avoid air pockets.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to an air source heat pump unit capable of automatically removing air. Background technique [0002] In the air source heat pump system, the air in the water pipeline is not easy to discharge, which will cause water flow failure. [0003] The commissioning of the air source heat pump hot water system is slightly different from that of the air conditioning system. The air source heat pump hot water system is a closed system and is prone to air stagnation. Therefore, the water system needs to be emptied before commissioning, otherwise it will easily lead to water flow failure. At present, the operation method of air source heat pump hot water system to discharge air needs to manually open the pipeline valve and pipeline water pump for emptying operation. Specifically: open the water supply valve, open the water pump and valve components of the hot water system, water pum...
