Sensor arrangement method for test of air conditioning system

Abstract

The invention discloses a sensor arrangement method for a test of an air conditioning system, and relates to the technical field of air conditioning systems, in particular to the sensor arrangement method for the test of the air conditioning system. The arrangement directions of an air conditioning system respectively comprise an air conditioning assembly air outlet, a foot blowing air outlet, anarrangement principle of a thermocouple, an evaporator temperature sensor, a warm air core body, a condenser temperature sensor, an air conditioning tube temperature and pressure sensor, system flow,system oil content, a head temperature sensor, a foot temperature sensor, an overall vehicle air outlet and ambient temperature outside a vehicle. According to the sensor arrangement method for the test of the air conditioning system, the situation of icing on the surface of an evaporator can be effectively avoided; the temperature distribution on the surface of the evaporator under different working conditions cannot be understood accurately if the temperature sensors on the surface of the evaporator are arranged unreasonably, so that the arrangement of the temperature sensors of the evaporator is affected; and by the arrangement method, icing risks in an operating process of the system can be reduced or completely eradicated as far as possible.

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
