JB/T 7249 Terminology of refrigeration equipment

3 Terms and definitions

The terms and definitions as established in JB/T 7249 AND the following terms

and definitions apply to this standard.

3.1

Unitary air conditioners

It refers to the equipment directly supplying the conditioned air to a confined

space, room, or area. It mainly includes refrigeration systems and air

circulation and purification devices, and it may also include heating,

humidification and ventilation devices.

3.1.1

Ducted air-conditioning (heat pump) units

It refers to the equipment directly supplying the centralized conditioned air

through air duct to a confined space, room, or area. It mainly includes

refrigeration systems and air circulation and purification devices, and it may

also include heating, humidification and ventilation devices.

It refers to the total amount of heat removed from (supplied into) the

confined space, room or area by the air conditioner in the unit time under the

specified cooling (heating) capacity test conditions, in the unit of W.

3.4

Cooling (heating) power input

It refers to the total power as consumed by the air conditioner during

operation under the specified cooling (heating) capability test conditions, in

the unit of W.

3.5

Energy efficiency ratio (EER)

It refers to the ratio between the cooling capacity of the air conditioner and

the cooling power input under the specified refrigeration capacity test

conditions, the value of which is expressed in W/W.

3.6

Coefficient of performance (COP)

It refers to the ratio between the heating capacity of the air conditioner and

the heating power input under the specified heating capacity test conditions,

the value of which is expressed in W/W.

3.7

Electrical heating devices used for heating

It refers to the electric heater which only uses the electric heating method for

heating purposes AND the electrical heaters which only uses the conversion

heat pump and electrical heaters such as temperature switch, etc., (the

switches action due to such factors as indoor and outdoor temperature, etc.)

for heating purposes (including post-mounted electric heater).

3.8

Additional electrical heating devices used for heating

It refers to the electrical heater which is used together with the heat pump

for heating purposes (including the post-mounted electrical heater).

3.9

It refers to, in the heating season, the ratio of the sum of the heat supplied

indoor during the heating operation of the air conditioner and the sum of the

consumed electricity, which is tested and calculated using the methods as

stated in Appendix C, AND expressed in W/W.

3.15

Annual performance factor (APF)

It refers to, in the cooling season and heating season, the ratio of the sum of

the heat removed from (supplied into) indoor during the cooling (heating)

operation of the air conditioner and the sum of the electricity consumed at

the same period, which is tested and calculated using the methods as stated

in Appendix C, AND expressed in W/W.

3.16

Single capacity air conditioner

It refers to the air conditioner free from capacity change except for the

changes caused by the compressor motor deviation due to load change.

3.17

Non-single capacity conditioner

It refers to the other air conditioners than those complying with 3.16.
