Introduction

Air enthalpy test method test device integrates a number of measuring instruments and systems, it is used as a test device for measuring the performance of the air conditioner, for many years It is widely used in air conditioner manufacturing. Since the content of air enthalpy test method, test conditions and other more complex, and the performance of the air conditioner Many parameters indicators involved for a long time to test air enthalpy test method Value test device has not yet formed a unified standard. In order to test Mortem inspection method using the air enthalpy method test equipment technical parameters standardized and unified, for purposes of each air-conditioner manufacturers use standardized and unified The air conditioner performance test apparatus, it is necessary to test the air enthalpy test method Value test apparatus standardized. This standard test method for measurement system verification process for each test air enthalpy value method test equipment involved has been described, and to A cold air enthalpy value of the rule of law, the calculation of heating capacity and cooling Measurement Uncertainty evaluation method, to regulate air enthalpy test test Value test device provides a reference and guidance. Air enthalpy test method test value unit test method
