To investigate the performance, cooling capacity and
power consumption tests are necessary. The experiments are
conducted by means of air-enthalpy test method in
a psychrometric chamber according to Chinese Standard GB/T
7725, 2004 Room Air Conditioners. The psychrometric
chamber consists of the indoor side and outdoor side, as
shown in Fig. 1. The conditions of air in both sides are
precisely adjustable in the form of dry bulb temperature/wet
bulb temperatures (DBT/WBT) to exactly satisfy the strict
requirements of temperatures and other needs in experiments.
The air temperature is maintained within 0.2 K and
measured by dry bulb and wet bulb thermometers with the
accuracy of 0.1 K. Furthermore, some data, e.g. air flow rate,
could be achieved by the apparatus equipped within the
psychrometric chamber inherently. The air flow is measured
by a nozzle flow meter with an accuracy of 1% FS.
