The enthalpy difference test is conducted in a standard enthalpy difference laboratory according to the GB/T7725-2004 standard for room air conditioners.
The main testable projects include the following:
√ Stable state rated cooling and heating (T1, T2, T3 operating conditions);
√ Customized heating with electric heating capacity;
√ Unsteady state test for low-temperature and ultra-low temperature heating;
√ Electric heating test;
√ Maximum operating cooling (heating) test;
√ Minimum operating cooling (heating) test;
√ Removal of condensed water;
√ Freeze;
There are four types of measurable models: (1) split type, (2) window type, (3) cabinet type, and (4) duct fan.
