Problems solved by technology

Now to solve this problem, most of the patents detect the water temperature through the normally closed solenoid valve, which is closed when the power is turned on, and the solenoid valve is opened to drain water after the power is turned off; in fact, the solenoid valve is in the closed state when the power is turned on most of the time, and there is a waste of resources; the fluctuation of the water temperature will cause water leakage. Frequent switching of the valve reduces the service life of the water valve

Embodiment 1

[0044] In this embodiment, an emergency automatic drainage device for an air-conditioning water system is provided, and the automatic drainage device includes: a battery, a controller and a drain valve, and the controller and the drain valve are both connected to the battery. The automatic drainage device can use a storage battery to supply power to the power-consuming parts of the device (at least one of the controller, the drain valve, etc.), and can also provide power to the power-consuming parts of the device through an air-conditioning power supply.

[0045] When the air-conditioning power supply is normally energized, if the air-conditioning power supply is used as the power supply for the controller and / or the drain valve, then when the air-conditioning power supply is powered off, the power supply for the controller and / or the drain valve is switched from the The air conditioner power supply is switched to the storage battery, and the drain valve is controlled by the co...

Embodiment 2

[0052] In this embodiment, a control method for an emergency automatic drainage device of an air-conditioning water system is provided. The control method adopts the automatic drainage device described in Embodiment 1, including: detecting whether the power supply of the air conditioner is powered off; Finally, the automatic drainage device is switched to be powered by the battery; it is judged whether to drain the air-conditioning water system according to the water supply temperature and return water temperature in the air-conditioning water system.

[0053] In this embodiment, the control method further includes: recording the drainage time when the air-conditioning water system is draining; judging whether the air-conditioning drainage has been emptied according to the drainage time: judging as has been emptied, close the drain valve. The judging whether to drain the air-conditioning water system according to the water supply temperature and return water temperature in the...

Abstract

The invention provides an emergency automatic drainage device of an air conditioner water system and a control method thereof. The automatic drainage device comprises an accumulator, a controller anda drainage valve; the controller and the drainage valve are both connected to the accumulator; when an air conditioner power supply is normally electrified, and if the air conditioner power supply isadopted as a power supply of the controller and / or the drainage valve for power supply, the power supply of the controller and / or the drainage valve is switched to the accumulator by the air conditioner power supply after the air conditioner power supply is failed, and the controller is used for controlling the drainage valve to drain water of the air conditioner water system.

Description

technical field [0001] The invention relates to an air-conditioning water system, in particular to an emergency automatic drainage device for an air-conditioning water system and a control method thereof. Background technique [0002] When the air conditioner is powered off, the antifreeze function of the unit will fail, failing to achieve the purpose of antifreeze. Therefore, need a kind of automatic drainage device of water system of air-conditioning equipment under the situation of power failure in autumn and winter. Now to solve this problem, most of the patents detect the water temperature through the normally closed solenoid valve, which is closed when the power is turned on, and the solenoid valve is opened to drain water after the power is turned off; in fact, most of the time the solenoid valve is in the closed state when the power is turned on, and there is a waste of resources; Frequent switching of the valve reduces the service life of the water valve.
