Multi-temperature-zone transportation refrigerating unit performance testing device and testing method

Abstract

The invention belongs to the technical field of transportation refrigerating unit testing, and particularly relates to a multi-temperature-zone transportation refrigerating unit performance testing device and a multi-temperature-zone transportation refrigerating unit performance testing method. The multi-temperature-zone transportation refrigerating unit performance testing device comprises a plurality of test rooms, an external environment room, heating modules and first temperature testing modules, wherein the plurality of test rooms are closed and thermally insulated, and are sequentially and adjacently arranged; the external environment room surrounds all the test rooms and serves as a simulated environment; the heating modules are used for heating air in each test room, and the firsttemperature measurement modules are for measuring the temperature in each test room, an air processing module used for adjusting the air state in the outer environment chamber is arranged on the outerenvironment chamber, and a second temperature measuring module used for measuring the temperature in the outer environment chamber is arranged on the inner side of the outer environment chamber; anda to-be-detected multi-temperature-zone transportation refrigerating unit can cool the air in each test room. According to the multi-temperature-zone transportation refrigerating unit performance testing device and the multi-temperature-zone transportation refrigerating unit performance testing method, a mode that the plurality of test rooms are sleeved with the outer environment room, heat is transferred and heat balance is established by means of the wall surfaces of the plurality of test rooms, and therefore the purpose of testing the performance of the multi-temperature-zone transportationrefrigerating unit is achieved.

Description

technical field [0001] The invention belongs to the technical field of testing multi-temperature zone transport refrigeration units, and in particular relates to a performance test device and a test method for multi-temperature zone transport refrigeration units. Background technique [0002] Transportation refrigeration units are an important part of cold chain refrigerated vehicles. At present, there are more and more domestic related manufacturers, and the products are uneven. There is an urgent need for a unified performance testing method to regulate. However, the performance test methods and test devices for transport refrigeration units in my country are mainly aimed at units with a single temperature zone, and there is a lack of test methods, standards and test devices for units with multiple temperature zones. Most of the domestic enterprises focus on the introduction of foreign technology, and the performance parameters provided mostly refer to foreign product samp...
