Embodiment 1

[0032] combined with figure 1 , the present embodiment provides a method for measuring the cooling performance of an umbrella, comprising the following steps:

[0033] S1. Place the umbrella to be tested equipped with multiple temperature acquisition devices in an environment with a set light intensity e, and place it open for at least 10 minutes;

[0034]S2, within the continuous time t, the temperature acquisition device collects the temperature Ti inside the umbrella and the temperature To outside the umbrella in real time;

[0035] S3. The control system analyzes the temperature Ti inside the umbrella and the temperature To outside the umbrella collected by the temperature acquisition device to obtain the temperature difference ΔT;

[0036] S4. Calculate the temperature difference rate R between the temperature Ti inside the umbrella and the temperature To outside the umbrella, R=△T / To×100﹪.

[0037] In this embodiment, the temperature difference rate R represents the le...

Embodiment 2

[0049] combined with figure 1 , the measuring method of umbrella cooling performance of the present embodiment, compared with the technical scheme of embodiment 1, also comprises S5 step, and described S5 step is the temperature difference rate R that the control system obtains in the continuous time t according to S4 step , to obtain the fluctuation size of the temperature difference rate.

[0050] In this embodiment, the value of the continuous time t is closely related to people's daily habits of using umbrellas, such as people's habit of using umbrellas outdoors for half an hour, 1 hour, 1.5 hours and other time values. During the cooling performance test, a high temperature difference rate means good sun protection and cooling performance; calculating the variance value of the temperature difference rate R within a continuous time t represents the fluctuation of the sun protection and cooling performance of the umbrella within a continuous time t. If the variance A small...

Embodiment 3

[0052] Compared with the technical solution of Example 2, in the method for measuring the cooling performance of the umbrella in this embodiment, in step S5, according to the fluctuation of the temperature difference rate R in different time t, the durability performance level under the same cooling and sun protection performance level is carried out. division.

[0053] In actual application, when t is 30 minutes, the temperature difference rate R of the umbrella to be tested will basically reach a stable level. According to the fluctuation of the temperature difference rate R in different time t, the durability performance level under the same cooling and sunscreen performance level can be divided into High, Medium and Low. The high level means that the temperature difference rate R of the umbrella to be tested fluctuates less within 4-5 consecutive hours, the medium level means that the temperature difference rate R of the umbrella to be tested fluctuates less within 2-3 con...

Abstract

The invention discloses a method and a system for measuring the cooling performance of an umbrella, and relates to the technical field of umbrella cooling performance detection. The method for measuring the cooling performance of the umbrella comprises the steps that S1, a to-be-measured umbrella provided with a plurality of temperature collecting devices is placed in the environment with the set illumination intensity e, and the to-be-measured umbrella is unfolded and placed for at least 10 minutes; s2, the temperature acquisition device acquires the temperature Ti inside the umbrella and the temperature To outside the umbrella to be measured in real time within the continuous time t; s3, the control system performs analysis according to the temperature Ti in the umbrella and the temperature To outside the umbrella to be detected, which are acquired by the temperature acquisition device, so as to obtain a temperature difference T; and S4, the temperature difference rate R of the temperature Ti inside the to-be-measured umbrella and the temperature To outside the to-be-measured umbrella is calculated, wherein R = T / To * 100%. According to the measuring method, the cooling and sun-blocking performance of the umbrella in the real using process can be visually reflected, and the accuracy of measuring the cooling performance of the umbrella through the measuring method is high.

Description

technical field [0001] The invention relates to the technical field of umbrella cooling performance detection, in particular to a method for measuring the cooling performance of an umbrella and a measurement system thereof. Background technique [0002] Summer is high temperature and the weather is hot. People often hold parasols when they go out, and ordinary parasols can only prevent sun protection and cannot meet people's needs when they are outdoors. At present, there are many different types of umbrellas with cooling functions on the market, such as treating the umbrella surface by setting a cooling reflective coating, spraying water mist inside the umbrella, installing an air supply device inside the umbrella, using heat-insulating and cooling nano-materials, and multi-layer umbrellas. Sunscreen fabrics and other methods to achieve the cooling function of the umbrella. However, due to the lack of measurement methods for detecting the cooling performance of umbrellas i...
