Psychrometric Calorimeter - tk-008

General
The calorimeter is designed to determine the thermal performance of unitary air conditioners and split systems by the air enthalpy method, and conforms to Standard GB/T 7725-2004 and JIS B 8615-1. It is an important and useful means for user to research and develop the product, and control the quality of the product.
The calorimeter includes two insulated rooms (indoor and outdoor), and a set of the air handling unit in each room, then the conditions in both rooms can be controlled accurately. In addition, an air flow measuring apparatus is provided in the indoor room to measure the air flow rate and the enthalpy of the air as it exits the unit under test. The air flow measuring apparatus is composed of a premium chamber, an air-flow receiving chamber, some nozzles, a rectifying unit, an exhaust fan, etc.
The calorimeter is able to control such parameters as Indoor Room Dry Bulb Temperature, Indoor Room Wet Bulb Temperature, Outdoor Room Dry Bulb Temperature, Outdoor Room Wet Bulb Temperature or Relative Humidity, Indoor Room Airflow of the Unit Under Test, and the Power Voltage, Frequency of the Unit Under Test. All controlled and measured parameters are collected into the data acquisition system and computer.
Calorimeter for Central Air Conditioner system can be manufactured (composed of four insulated rooms).
