Air conditioning drainage system, drainage control method and air conditioning indoor unit

Abstract

The invention discloses an air conditioning drainage system, comprising a water storage device, a control device, and a drainage water pump and a liquid level detecting device connected with the control device, wherein the liquid level detecting device comprises a first liquid level detecting device and a second liquid level detecting device, and installation positions of the first liquid level detecting device and the second liquid level detecting device have a height difference, so that the liquid level upper limit of the first liquid level detecting device is not higher than the liquid level lower limit of the second liquid level detecting device. The air conditioning drainage system enables the water level detection of air conditioning condensed water to become more precise, facilitates action control of the water pump more reasonably, and improves the control precision of the water pump. The invention further discloses a drainage control method of the air conditioning drainage system and an air conditioning indoor unit.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning drainage system. The present invention also relates to the drainage control method of the air conditioning drainage system and the air conditioning inner unit. Background technique [0002] When the air conditioner is cooling, condensed water will inevitably be generated in the internal unit of the air conditioner. If the water cannot be removed from the unit in time, it will eventually overflow the unit due to excessive accumulation of condensed water, resulting in water dripping or The problem of water leakage causes loss and inconvenience to users. Therefore, the inner unit of the air conditioner usually has its own drain outlet, and the water is discharged to a position lower than the inner unit of the air conditioner through the drain pipe by gravity, for example, to the outside. However, due to the limitation of the installation environment, s...

Problems solved by technology

This leads to complex drainage control logic and low reliability, especially when the air conditioner is faulty or shut down, the control of the water pump is not precise enough

For example, if the water pump stops working after the air conditioner is shut down, if the evaporator of the air duct machine freezes during the shutdown, the ice on the evaporator will produce a large amount of water after melting, which may still cause the internal unit of the air conditioner to overflow; After the water pump stops working after a period of delay, then under normal working conditions, there will be no condensed water after stopping, but the water pump keeps running. This situation will generate noise on the one hand, and cause Energy waste
