Problems solved by technology

[0003] In traditional air-conditioning and refrigeration systems, multiple pressure switches are required to control different rated safety pressures, which not only increases the production cost of the air-conditioning and refrigeration system, but also increases the space occupied by the installation of pressure switches and the probability of failure

Abstract

The invention discloses an air-conditioning switch. A triple-voltage switch integrates three functions of low-voltage control, medium-voltage control and high-voltage control of a refrigerant in an air-conditioning refrigerating system, so that the triple-voltage switch can control the stock of the refrigerant of the refrigerating system, i.e. low-voltage control, starting and stopping of a cooling fan, i.e. medium-voltage control, and starting and stopping of a compressor, i.e. high-voltage control. Therefore, in the air-conditioning switch, not only is the production cost of the air-conditioning refrigerating system reduced, but also the occupied space and the fault probability are reduced when the voltage switch is installed.

Description

technical field [0001] The invention relates to an air conditioner switch, in particular to a composite triple pressure switch capable of simultaneously detecting and controlling low pressure, medium pressure and high pressure of refrigerant in an air conditioner and refrigeration system. Background technique [0002] Automobile air-conditioning and refrigeration systems generally install various forms of pressure switches to detect and control the pressure of the refrigerant in the air-conditioning and refrigeration system. According to different design requirements: single pressure switch, double pressure switch, triple pressure switch, and even quadruple pressure switch. The function of the pressure switch is that when the pressure in the system is higher or lower than the rated safety pressure, the diaphragm in the sensor moves instantaneously, and the related switch joint is connected or disconnected through the connecting guide rod. When the pressure drops or rises to ...
