AI Technical Summary

Technical Problem

In existing air conditioning comfort laboratories, load adjustment of brick wall structures is difficult and the load cannot be accurately calculated, affecting testing efficiency. Water coils cause condensation problems when put into operation, and the load of insulated panels in the laboratory is too small to accurately simulate the actual air conditioning operation.

Method used

The inner and outer chambers are enclosed by insulation materials, and air intake and exhaust channels are set up. The heat load of the inner chamber is controlled by adjusting the amount of hot and cold air in the outer chamber through the air circulation system. The air flow is adjusted by the intake and exhaust fans of the air circulation system to avoid disturbing the air flow field in the inner chamber and achieve stepless adjustment of the load.

Benefits of technology

It achieves precise load control, reduces environmental stabilization time, improves laboratory testing efficiency and utilization, avoids condensation problems, and ensures air quality and the reliability of experimental results.

Abstract

This invention belongs to the field of heat load regulation technology, specifically relating to an air-conditioned comfort environment laboratory with controllable heat load, comprising an inner chamber, an outer chamber, and an air circulation system. Both the inner and outer chambers are enclosed spaces, with the inner chamber located within the outer chamber and enclosed by insulation material. The air circulation system includes an intake airway and an exhaust airway connecting the inner and outer chambers. This invention controls the heat load within the inner chamber by changing the amount of hot or cold air entering the outer chamber through the air circulation system. This solves the common problems of difficult load regulation and inaccurate load calculation in brick-walled thermal environment test chambers, and avoids the problem of insufficient load in previous laboratories based on insulated panels. Furthermore, it has advantages over the condensation problem on the inner chamber walls caused by using water coils to apply the load. It reduces the environmental stabilization time and significantly improves the utilization rate of the laboratory.
