Description

  The present invention relates to an apparatus for demonstrating performance such as heat insulation and heat insulation of plate glass mainly used for glass windows and glass doors.

Conventionally, performances such as heat insulation and heat insulation of architectural glass are shown in catalogs and pamphlets with photographs, performance values, graphs, etc., and the user grasps the performance from these data and determines whether or not it can be adopted. By the way, performances such as heat insulation and heat insulation are generally difficult to understand with numerical values and graphs for engineers, and there is a problem that they are not easily transmitted.

A glass plate is attached and sealed to seal the cool air at the front opening of the box, and each small space is sealed. A heat source and a temperature sensor with the same conditions are placed in the box, and a temperature indicator that displays the temperature value measured by each temperature sensor is attached to the box so that the insulation of each glass sample against cold air can be demonstrated. The supply means is in the performance comparison demonstration apparatus for architectural glass, in which solid dry ice is housed in the upper part of the box and the cold air of the dry ice is sent to the lower space .

According to the present invention, by directly showing the user the status of a product under experiment, the state and performance of the product can be understood more objectively.
