Temperature measuring device for simulating residential area bituminous pavement heat island effect

Abstract

The invention relates to a temperature measuring device for simulating the heat island effect of an asphalt pavement in a residential area. The device comprises an environment box, a thermal resistor,an asphalt concrete plate, a cement concrete cube, a green paperboard, a simulation light source and a lamp holder, wherein the environment box is insulated from the outside; the thermal resistor measures the temperature of different positions in the environment box; the asphalt concrete slab simulates an asphalt pavement; the cement concrete cubic blocks simulate house buildings, and residentialareas with different building densities are simulated through dense or sparse arrangement; the green paperboards simulate greenbelts of residential areas and are combined with the concrete blocks foruse; the simulation light source adopts an iodine-tungsten lamp to play a heating role; the lamp bracket fixes the light source and can adjust the incident angle of the light source. The device can freely combine asphalt concrete slabs, cement concrete blocks and green paperboards according to test requirements, and meets various building distribution types. The temperature of multiple positionsis measured through the thermal resistor, so temperature distribution of the residential area is obtained.

Description

technical field [0001] The invention relates to a temperature measuring device for the heat island effect of an asphalt pavement in a residential area, and belongs to the field of evaluation of the urban residential area heat island effect. Background technique [0002] With the rapid development of economy, the pace of urbanization is getting faster and faster. In order to meet the ever-increasing urban living and transportation needs, the building density continues to increase and the road area continues to increase, resulting in an increasingly significant urban heat island effect in summer, which seriously reduces human comfort and endangers the health of residents. [0003] At present, in order to evaluate the urban heat island effect, meteorological data acquisition devices, infrared image acquisition devices, and suburban temperature acquisition devices are commonly used to test temperature and wind speed. But these devices have the following disadvantages: [0004]...

AI Technical Summary

Problems solved by technology

[0004] (1) The tests are all carried out outdoors, and the weather conditions have a great influence. Wind speed, sun incidence angle, etc. will have a great impact on the test results

And for a set of measured data, it is impossible to perform repeatable tests under the same wind speed, incident angle or weather conditions, that is, the test results cannot be repeated;

[0005] (2) The actual measurement can only test t...
