Abstract

The invention discloses an on-off control device and system. The on-off control device comprises a detector, a controller and a relay. The detector is used for detecting whether combustible refrigerating fluid of an air conditioner leaks to obtain a detection result, and generating a detection signal according to the detection result. The controller comprises the receiving end and the controlling end and generates a control signal according to the detection signal, wherein the receiving end is connected to the detector. The first end of the relay is connected to the controlling end and used for being connected with a power source, the second end of the relay is connected to the air conditioner, and the relay is used for opening or closing a circuit where the air conditioner is located according to the control signal. According to the on-off control device and system, the problem that the potential safety hazards such as combustion and explosion caused by leakage of the combustible refrigerating fluid can not be prevented in the correlation technique is solved.

Description

technical field [0001] The invention relates to the field of switches, in particular to a switch control device and system. Background technique [0002] Most of the existing air conditioners use R22, R410A, R134A and other refrigerants, wherein the air conditioners include dehumidifiers. R22, R410A, etc. are non-clean refrigerants that can destroy the ozone layer of the atmosphere. Therefore, if the air conditioner uses a large amount of the above refrigerants, it will easily cause the greenhouse effect. [0003] At present, refrigerants with low Global Warming Potential (GWP) such as R290 (that is, propane) and R32 have been used as substitutes for R22, R410A, R134A and other refrigerants in refrigeration and dehumidification systems such as air conditioners. . However, R290, R32, etc. are flammable refrigerants. Once the air conditioner has refrigerant leakage failure, it is easy to cause safety hazards such as combustion and explosion. However, in related technologies...
