Simple device for measuring temperature uniformity and volume of outlet air of vehicle air conditioner

Abstract

The invention belongs to the technical field of vehicle air conditioner test devices, and relates to a simple device for measuring the temperature uniformity and the volume of outlet air of a vehicleair conditioner. The device comprises a refrigeration air-supply system, a heating system and a control system for controlling all parts, wherein the refrigeration air-supply system and the heating system replace an existing compressor, a condenser, an engine and the like, and provide hot air, cold air and different air pressures for a to-be-measured air conditioning cabinet, the influence on theinlet air of the air conditioner can be simulated at different running speeds of a vehicle, the uniformity of the temperature at various air outlets of the air conditioning system is measured, and whether the volume and the temperature of the outlet air of a heat air core and an evaporator core meet standard requirements or not is tested. The structure of the device is simple, the test process iseasier to control, the test result is more accurate, and the device is an innovation of a linear test device of the vehicle air conditioner.

Description

technical field [0001] The invention belongs to the field of testing equipment for automobile air conditioners, and in particular relates to a simple testing equipment for the temperature uniformity and air volume of the air outlet of an automobile air conditioner. Background technique [0002] The working principle of the car air conditioner is: when heating, the medium in the water tank of the car is heated by the car engine, and then when the medium passes through the warm air core, the air conditioner blows out hot air; The refrigerant cools down, and when the low-temperature refrigerant passes through the evaporator core, the air conditioner blows cold air. [0003] In order to detect the uniformity of the temperature of each air outlet of the air conditioning system under the condition of different openings of the damper of the air conditioning system and different wind pressures of the vehicle (that is, to simulate the influence of different operating speeds of the ve...

AI Technical Summary

Problems solved by technology

[0004] At present, the temperature uniformity and air volume test of automobile air conditioners need to build an enthalpy difference performance laboratory for testing according to QC T 657-2000. There are problems such as huge investment in equipment and low efficiency of equipment functions.

[0005] However, other simple benches cannot meet the requirements of voltage, current, heating air flow, cooling capacity adjustment, zero-adjustment fan voltage adjustment, and temperature acquisition module acquisition and adjustment functions in the test specifications of Changan, Ford, Mazda, and Geely.
