Walk-in high and low temperature alternating humidity and heat test room

Abstract

The invention relates to the field of test equipment, in particular to a step-in high and low temperature alternating damp and heat test room which comprises a test bin and an equipment bin, the test bin is provided with two heat preservation doors, observation windows are arranged on the heat preservation doors, the two heat preservation doors divide the test bin into a transition bin and an environment bin, an illuminating lamp is arranged in the transition bin, and the equipment bin is provided with an illuminating lamp. A circulating air duct and a fresh air duct are arranged in the environment bin, a first fan, an evaporator, a heater, a dry and wet bulb sensor and a humidifying spray head are arranged in the circulating air duct, and the system further comprises a control system. According to the step-in type high-low temperature alternating humidity and heat test room, the transition bin is designed, and when experimenters enter and exit from the test room, the situation that a large amount of outdoor air is mixed in and influences the stability of the air condition in the test box can be effectively avoided. Due to the design of the humidifier, water does not need to be frequently and manually added into the laboratory, and only the water tank needs to be connected to a tap water pipe. The laboratory is simple in structure and low in manufacturing cost, and has good market popularization value.

Description

technical field [0001] The invention relates to the field of test equipment, in particular to a walk-in high and low temperature alternating damp heat test chamber. Background technique [0002] The test chamber is a general term for the products of the environmental testing industry, which simulates the natural climate environment within a limited space. test box, etc. [0003] The large walk-in high and low temperature humidity and heat test box is mainly used for various types of road vehicles and containers and other large equipment to carry out various thermal performance tests and environmental climatic conditions tests. The main test items of the test box include: air conditioning performance, heating performance, thermal insulation performance and air tightness performance of passenger cars; cooling performance, heating performance and air tightness performance of thermal insulation vehicles; cooling performance, heating performance of refrigerated containers, refri...

AI Technical Summary

Problems solved by technology

[0004] Due to the large space in the large-scale high and low temperature humidity and heat test chamber, and there are many items that meet product testing, testers need to enter and exit the test chamber frequently. In the low-temperature laboratory, air at normal temperature enters the test chamber immediately, resulting in frost and condensation, which seriously affects the stability of the air condition in the test chamber and adversely affects the reliable operation of the equipment
