A sensor layout method for air conditioning system test

Abstract

The invention discloses a sensor layout method for an air conditioning system test, relates to the technical field of air conditioning systems, and specifically relates to a sensor layout method for an air conditioning system test. Arrangement principle of tuyere and thermocouple, evaporator temperature sensor, warm air core, condenser temperature sensor, air conditioning pipe temperature and pressure sensor, system flow, system oil content, head temperature sensor, foot temperature sensor, vehicle air outlet and the ambient temperature outside the vehicle. The air-conditioning system test sensor arrangement method can effectively avoid the occurrence of icing on the evaporator surface. If the evaporator surface temperature sensor is not arranged properly, it will not be possible to accurately understand the temperature distribution of the evaporator surface under different working conditions, thereby affecting The arrangement of the evaporator temperature sensor, and the arrangement method, can minimize or eliminate the risk of icing during system operation.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to a method for arranging sensors for air-conditioning system tests. Background technique [0002] The sensors of the automatic air conditioning control system generally include the temperature sensor inside the cabin, the temperature sensor outside the cabin, the evaporator temperature sensor, the solar sensor, the water temperature sensor, etc., among which the water temperature sensor is located at the engine water outlet, and it will feed back the cooling water temperature to the ECU. When the temperature is high, the ECU can disconnect the compressor clutch to protect the engine. At the same time, the ECU can control the valve of the cooling water leading to the heating core according to the water temperature. Each sensor will feed back the temperature information to the ECU. Control the temperature of the air flow, for example, when the temperature is too low,...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sensor arrangement method for air conditioning system test, which solves the problem that the sensor arrangement position proposed in the above-mentioned background technology is not comprehensive enough, which indirectly leads to icing on the surface of the evaporator, large temperature difference at the air outlet and errors. Judgment of system capabilities, and increased analysis costs, can not meet people's needs and other issues
