Problems solved by technology

However, due to the limitations of the processing conditions such as the current pipeline flanging process, bending process and welding process, the pipeline section connecting the safety valve 4 and the exhaust valve 3 is very long, resulting in increased water system resistance, system heat loss, and increased product costs. As well as the increased risk of water leakage in household machine water systems due to the large number of threaded connections

Abstract

The invention provides a water system protection device, a control method, a water system and an air conditioner. The water system protection comprises a shell and a liquid level detection part, wherein the shell is provided with an accommodating cavity, a gas-liquid inlet is formed in a first end of the shell, an exhaust valve is arranged at a second end of the shell, and a drainage valve is arranged on the peripheral wall of the shell; and the liquid level detection part is arranged in the accommodating cavity and used for detecting the liquid level position in the accommodating cavity and controlling the exhaust valve and the drainage valve according to the liquid level position. By means of the water system protection device, the number of connection pipelines can be decreased.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a water system protection device, a control method, a water system and an air conditioner. Background technique [0002] In the existing technology, such as figure 1 As shown, the water system of a household air conditioner includes a casing heat exchanger 1, a connecting water pipe 2, a water pump 5, and air pressure and water pressure safety protection devices. The air pressure and water pressure safety protection devices are respectively an exhaust valve 3 and a safety valve 4 , The exhaust valve 3 is used to remove the air in the water system, and the safety valve 4 is used to prevent the system from being damaged due to excessive pressure in the water system. In order to ensure safety, the installation position of the safety valve 4 and the exhaust valve 3 must be installed at the highest point of the water system. However, due to the limitations of the processing...
