無線式墻體傳熱系數(shù)現(xiàn)場檢測儀（現(xiàn)場墻體傳熱系數(shù)測定儀）
一、產(chǎn)品概述
WH-2無線式建筑圍護(hù)傳熱系數(shù)現(xiàn)場檢測儀是依據(jù)GB/T23483-2009《建筑物圍護(hù)結(jié)構(gòu)傳熱系數(shù)及采暖供熱量檢測方法》、JGJ/T 132-2009《居住建筑節(jié)能檢驗(yàn)標(biāo)準(zhǔn)》、JGJ/T 357-2015《圍護(hù)結(jié)構(gòu)傳熱系數(shù)現(xiàn)場檢測技術(shù)規(guī)程》等標(biāo)準(zhǔn)采用智能觸摸屏和物聯(lián)網(wǎng)模塊研制開發(fā)的高精度、低功耗的新一代檢測儀器。
該檢測儀是通過控制熱箱內(nèi)溫度，人為造成試件兩側(cè)溫差，在相對穩(wěn)態(tài)條件下進(jìn)行測量，從而提高總體測試精度。該檢測儀適用于建筑圍護(hù)結(jié)構(gòu)傳熱系數(shù)現(xiàn)場檢測和實(shí)驗(yàn)室檢測。通過采集試件表面的熱流密度、內(nèi)外表面溫度之差計(jì)算出試件的熱阻值。最后再算出傳熱系數(shù)。
優(yōu)勢特點(diǎn)：
1、具有體積小、精度高、操作方便等特點(diǎn)。
2、在溫度采集方式上，特別是外表面溫度的采集，由于受建筑結(jié)構(gòu)的影響，通常需要進(jìn)行長距離的布線，施工.麻煩且費(fèi)用高。本檢測儀對于外墻溫度的采集采用無線通訊方式，去掉溫度傳感器與檢測采集儀的線纜連接，從而簡化了施工難度，避免了由于通訊線纜帶來的穿墻打洞布線等的麻煩，使檢測變得更加方便快捷。
3、實(shí)現(xiàn)通信距離zui高可達(dá)150米（室內(nèi)）或300米（空曠），在室內(nèi)可以隔墻傳輸10～15層左右；
4、采用了高智能低功耗的無線通訊技術(shù)，提高了電池的使用壽命，根據(jù)不同的使用情況電池壽命可達(dá)2~3年；
5、具有斷電保持的功能。更換電池不會影響試驗(yàn)。更換電池后儀器自動進(jìn)行數(shù)據(jù)傳輸，繼續(xù)完成試驗(yàn)過程。

Wireless On-site Wall Heat Transfer Coefficient Tester
I. Product Overview
The WH-2 Wireless Building Envelope Heat Transfer Coefficient Tester is a new generation of high-precision, low-power testing instrument developed in accordance with standards such as GB/T 23483-2009 Test Methods for Heat Transfer Coefficient of Building Envelopes and Heating Supply, JGJ/T 132-2009 Energy Efficiency Inspection Standard for Residential Buildings, and JGJ/T 357-2015 Technical Specification for On-site Detection of Heat Transfer Coefficient of Building Envelopes. It utilizes an intelligent touch screen and IoT modules.
The tester artificially creates a temperature difference across the specimen by controlling the temperature inside the hot box. Measurements are taken under relatively steady-state conditions to ensure high testing accuracy. It is suitable for both on-site detection of building envelope heat transfer coefficients and laboratory testing. The instrument calculates the thermal resistance of the specimen by collecting the heat flux density and the temperature difference between the inner and outer surfaces, and subsequently derives the heat transfer coefficient.
Advantages & Features
-
Compact & Precise: Features a small footprint, high accuracy, and user-friendly operation.
-
Wireless Innovation: Traditional bs require extensive wiring through walls for exterior surface temperature measurement, which is costly and labor-intensive. This device uses wireless communication for exterior wall temperature collection, eliminating the need for cable connections, simplifying construction, and avoiding the hassle of drilling holes.
-
Long-Range Communication: Achieves a communication distance of up to 150 meters indoors (capable of penetrating 10–15 walls) or 300 meters in open areas.
-
Low Power Consumption: Utilizes intelligent low-power wireless technology, extending battery life to 2–3 years depending on usage.
-
Power Failure Protection: Features data retention during power outages. Battery replacement does not interrupt the test; the instrument automatically resumes data transmission and continues the testing process upon battery replacement.
