Abstract

The invention relates to an air source heat pump unit which comprises an outdoor unit, an indoor unit, at least two pieces of end equipment and a control module, wherein the at least two pieces of end equipment are connected with the indoor unit; the control module can divide the end equipment into first and second end equipment. When an automatic emptying function is started, emptying is carried out according to an emptying period circularly. The emptying period comprises at least two first end equipment emptying times, at least two first end equipment system water path stabilizing times, at least two second end equipment emptying times and at least two second end equipment system water path stabilizing times. The air source heat pump unit comprises control of emptying air of a hot water system intactly without manual operation, so that air in the water system can be excluded thoroughly and air frustration is avoided.

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...
