operation under the rating working status and the specified condition.
⑷Heating capacity
It means the total quantity of heat per unit time transferred by the air-conditioner to the closed space,
room or area under the rating working status and specified condition. Unit: W or BTU.
⑸The consumed power for heating:
The total power input for air-conditioner’s heating operation under the rating working status and the
specified condition Unit: W.
⑹Energy and efficiency ratio (EER)
It means the ratio of the cooling capacity to the effective input power consumption occurred during
the air-conditioner’s refrigeration process under the rating working status and the specified condition.
W/W stands for the value of the ratio.
⑺Coefficient of Performance (COP):
It means the ratio of the cooling capacity to the effective input power consumption occurred during
heating process of the heat pump of the air-conditioner under the rating working status and the
specified condition. W/W stands for the value of the ratio.
Note: * The effective input power consumption stands for the average electric power inputted to the
air-conditioner within a unit time, which includes:
① The input power shared for the operation of the compressor and the input power for
defrosting.(Except the auxiliary assistant electric heating devices with no aim to
defrosting);
② The input power of all control and safety devices;
③ The input power of the heat exchange transferring devices(Fan and pump);
Energy efficiency ratio (EER): It means the ratio of the
cooling capacity to the effective input power
occurred during the air-conditioner’s refrigeration process under the rating working status and the
specified condition. W/W stands for the value of the ratio.
⑻The volume of circulating air (The volume of air delivered to room):
The volume of air delivered by the air-conditioner to the airtight space, room or area per unit time
under the rating refrigerating working condition when the aeration door and the ejection door are
closed thoroughly (If applicable). The unit of the volume of air delivered is: m3/s（m3/h）.
⑼ Air enthalpy-difference testing method
It’s a test method being applied in the measurement of the air-conditioner’s performance of cooling
and heating. The parameters in the need of the test include the outlet air parameter, the inlet air
parameter and the volume of the circulating air of the air-conditioner. The performance of the
air-conditioner is determined by the product of the volume of air and the difference between the
enthalpy values of the outlet and inlet air.
The cooling capacity of the air-conditioner is relating to the area of the room, room’s usage, room’s
orientation, and the floor it at, the room’s heat preservation capability, the quantity of heat from other
