1980年底，科罗拉多州的一个设施建造了第一个垂直流的原型岩层。led被安装在测试回路上，并根据合同和ASFIRAE标准94-77完成了一系列热性能测试。安装了额外的仪器，并进行了测试，以确定内部气流特性。在不同的流速、温度和流向下完成了充电、放电和热损失测试。本文讨论了在不同流速、温度和流向下完成的充电、放电和热损失试验。引用:研讨会，ASHRAE交易，第88卷，第2部分，加拿大多伦多

The first prototype rock bed with vertical flow was constructed at a facility in Colorado in late 1980. The led was instrunented and attached to the test loop, and a series of thermal performance tests were completed in accordance with the contract and in general accordance with ASFIRAE Standard 94-77. Additional instrumentation was installed and tests conducted to determine internal airflow characteristics. Charge, discharge, and heat loss tests were completed at various flow rates, temperatures, and flow directions.This paper discusses the charge, discharge, and heat loss tests were completed at various flow rates, temperatures, and flow directions.
