Multi-temperature zone transport refrigeration unit performance test test device and test method

Abstract

The invention belongs to the technical field of testing transport refrigeration units, and in particular relates to a performance test device and a testing method for multi-temperature zone transport refrigeration units. The test device includes a plurality of closed and insulated test rooms arranged adjacently in sequence, and an external environment room that surrounds all test rooms as a simulated environment. The test device also includes a heating module for heating the air in each test room, and measures the temperature of each test room The first temperature measurement module of the internal temperature; the external environment room is provided with an air processing module for adjusting the air state in the external environment room, and the inner side is provided with a second temperature measurement module for measuring the temperature of the external environment room; multiple to be detected Zone transport refrigeration units cool the air in each test room. The invention adopts the mode between multiple test rooms and the external environment, conducts heat through the walls of multiple test rooms and establishes heat balance, so as to achieve the purpose of testing the performance of multi-temperature zone transport refrigeration units.

Description

technical field [0001] The invention belongs to the technical field of multi-temperature zone transport refrigeration unit testing, and in particular relates to a multi-temperature zone transport refrigeration unit performance test test device and a test method. Background technique [0002] Transport refrigeration units are an important part of cold chain refrigerated trucks. At present, there are more and more related domestic manufacturers, and the products are mixed, so there is an urgent need for a unified performance testing method to standardize. However, the performance test methods and test devices for transport refrigeration units in my country are mainly aimed at units in a single temperature zone, and there is a lack of test methods, standards and test devices for units in multiple temperature zones. Most domestic enterprises mainly introduce foreign technologies, and the performance parameters provided are mostly based on foreign product samples, and there is a ...

AI Technical Summary

Problems solved by technology

In the promotion and application of related technologies, manufacturers cannot provide users with accurate design parameters, which affects the promotion and use of multi-temperature zone units and hinders the promotion of such products

To sum up, at present, the field of multi-temperature zone transport refrigeration unit performance testing test equipment is still blank, and the performance testing device is urgently needed in the market to test the performance of multi-temperature zone transport refrigeration unit
