60K BTU Double Code Air - Enthalpy Method Calorimeter ISO 5151

60K BTU Double Code Air-Enthalpy Method Calorimeter ISO 5151

System introduction:

This air enthalpy method calorimeter lab consists of 1 indoor side room (Room A) and 1 outdoor side room (Room B). The refrigerating capacity, heating capacity and other performances of an air conditioner are tested by means of testing the lab parameters, such as temperature, pressure and electrical performance. This installation can be used to test the performance of various window type, split type, free-standing type and ceiling cassette type and duct type AC air conditioners, and can also be used for other standard operating condition related tests and expanded tests, meeting the need for product sampling inspection and product development. The laboratory is equipped with two stations, which can simultaneously test two sets of 1-Phase prototypes not larger than 30KBtu (to ensure total not large than 60K BTU), if only test one set of prototype once, then prototype can up to 60K BTU, but should not larger than 60K BTU.

In this test system, the operation of the equipment is controlled by a programmable controller and a HMI, test running data are collected by a high accuracy data collector, the data can be transferred at real time to an upper level computer for processing, the computer displays, stores, outputs and prints test reports.

Our technical staff has accumulated a wealth of practical experience.

Maximize the accuracy of your HVAC-R testing with our 60K BTU Double Code Air Enthalpy Calorimeter, designed and manufactured in strict accordance with ISO 5151 and other international testing standards. This advanced test system utilizes the recognized Air Enthalpy Method to measure the cooling and heating capacity of air conditioners, heat pumps, and split systems with unparalleled precision.

Ideal for research laboratories, quality assurance centers, and certification bodies, this calorimeter provides a complete solution for performance rating and energy efficiency verification.

Key Features:

• Air Enthalpy Method: Precisely calculates capacity by measuring the temperature, humidity, and airflow differential across the indoor unit, delivering accurate performance data without the complexity of refrigerant-side measurement.

• Dual-Standard Compliance (Double Code): Engineered to meet both ISO 5151 (Non-ducted air conditioners and heat pumps) and other major regional standards (such as AHRI 210/240 or GB/T 7725), ensuring your products are certified for global markets.

• 60K BTU Capacity: Specifically designed to test a wide range of residential and light commercial units, from small window ACs up to 5-ton (60,000 BTU/h) split systems and ducted units.

• Controlled Environmental Chambers: Includes precisely controlled indoor and outdoor side chambers (psychrometric rooms) that simulate extreme ambient conditions to test unit performance under various climate scenarios.

• Automated Data Acquisition: Integrated software platform controls the test sequence, monitors all sensors in real-time, and automatically generates comprehensive test reports, reducing human error and test time.

Ensure your cooling products meet the highest standards of efficiency and reliability with our ISO 5151-compliant Air Enthalpy Calorimeter.
