Example Embodiment

[0027] A method and device for air-conditioning water system exhaust control. By independently controlling the operation of the water pump on the main circuit of the water system of the indoor unit of the air-conditioning system, the air in the above-mentioned water system can be automatically discharged, which avoids the need to disassemble the water pump wiring and forcibly clean the air in the traditional air-conditioning system. The water pump is cumbersome to control, and there is no potential safety hazard. In addition, on the basis of automatic exhaust, the water flow switch on the main circuit of the water system is also monitored to avoid the failure of the water flow switch, which will cause the water system of the indoor unit to not work normally, and further cause damage to other loads of the air conditioning system. It is also beneficial to overhaul the air conditioning system. An air conditioning system, on the basis of the traditional cooling mode and heating mo...

Abstract

The invention discloses an exhaust control method of an air conditioning water system. The method comprises the steps of: opening a water pump; detecting a state of a water current switch in a continuous second preset time after starting the water pump for a first preset time; closing the water pump if the state is off; and continuously opening the water pump if the state is on, and exhausting air in a water circulating main loop from a water system through an automatic exhaust valve. The operation of the water pump on the water system main loop of an indoor unit of an air conditioning system is independently controlled, so that the automatic exhausting of the air in the system is realized, the troubles of disassembly of water pump wires and forced control of the water pump in traditional exhausting are prevented, and the potential safety hazards are not generated. Meanwhile, the invention further discloses an exhaust control device of the air conditioning water system and an air conditioning system.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning water system exhaust control method, an air conditioning water system exhaust control device and an air conditioning system. Background technique [0002] When the existing air conditioner is installed and debugged, there is a problem that it is difficult to exhaust the air inside the water system. For small household central air-conditioning water machines, the water pumps in the unit are integrated on the whole machine and controlled by the whole machine, so the water pumps cannot be independently controlled to start and stop freely. This will lead to the fact that when the unit is installed and debugged for the first time to replenish water, it is easy for the unit to not have enough power source to circulate the water inside the system during the water replenishment process, resulting in residual air in the water system, and the water flow rate is...
