30K BTU Single Code Test Laboratory Air Enthalpy Method Calorimeter
System overview
This air enthalpy method calorimeter lab designed and manufactured
by 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
one station, which can test 1 set of 3-Phase prototypes not larger
than 30KBtu.
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.
