3.3

conditioned space

enclosed space, room or zone to which conditioned air is delivered

3.4

dehumidifer

encased assembly designed to remove moisture from its surrounding atmosphere using either an electrically operated refrigeration system or a desiccant type of material including a means to circulate air and a drain arrangement for collecting and storing and/or disposing of the condensate

3.5

total power input

P_t

average electrical power input to the equipment as measured during the test

Note 1 to entry: Total power input is expressed in units of watts.

3.6

ventilation airflow

rate of flow of air introduced to the conditioned space through the equipment

equalizer opening airflow

rate of flow of air from the outdoor side through the equalizer opening in the partition wall of a calorimeter to the indoor side

Note 1 to entry: See Figure 1.

3.8

evaporatively cooled condenser

heat exchanger that condenses refrigerant vapour by rejecting heat to a water and air mixture causing the water to evaporate and increase the enthalpy of air

Note 1 to entry: Desuperheating and sub-cooling of the refrigerant may also occur.

3.9

exhaust airflow

rate of flow of air from the indoor side through the equipment to the outdoor side

Note 1 to entry: See Figure 1.

3.10

full-load operation

operation with the equipment and controls configured for the maximum continuous duty refrigeration capacity specified by the manufacturer and allowed by the unit controls

3.11

heating capacity

amount of heat that the equipment can add to the conditioned space (but not including supplementary heat) in a defined interval of time

Note 1 to entry: Heating capacity is expressed in units of watts. Manually selectable supplementary heaters are disabled during capacity tests, but any automatic supplementary heaters are permitted to operate.

3.12

indoor compartment

indoor-side compartment

testing room simulating the conditioned space (and containing the tested appliance)

Note 1 to entry: See Figure 1.

3.13

indoor discharge airflow

rate of flow of air from the outlet of the equipment into the conditioned space

Note 1 to entry: See Figure 1.

3.14

indoor heat exchanger

heat exchanger which is designed to remove heat from the indoor part of the building or to transfer heat to it

Note 1 to entry: In the case of an air conditioner or heat pump operating in the cooling mode, this is the evaporator. In the case of an air conditioner or heat pump operating in the heating mode, this is the condenser.

3.15

indoor intake airflow

rate of flow of air into the equipment from the conditioned space

Note 1 to entry: See Figure 1.

3.16

latent cooling capacity

amount of latent heat that the equipment can remove from the conditioned space in a defined interval of time

Note 1 to entry: Latent cooling capacity is expressed in units of watts.

Note 2 to entry: “Latent cooling capacity” is also known as “room dehumidifying capacity”.

3.17

leakage airflow

rate of flow of air interchanged between the indoor side and outdoor side through the equipment as a result of its construction features and sealing techniques

Note 1 to entry: See Figure 1.

3.18

non-ducted portable air-cooled air conditioner having a single exhaust duct

encased assembly, designed primarily to provide free delivery of conditioned air to an enclosed space, room or zone which takes its source of air for cooling the condenser from the conditioned space, and discharges this air through a duct to the outdoor space

Note 1 to entry: Such air conditioners comprise a primary source of refrigeration for cooling and dehumidification. They can also include means for heating other than a heat pump, as well as means for circulating, cleaning, humidifying, ventilating or exhausting air.

3.19

non-ducted portable air-cooled heat pump having a single exhaust duct

encased assembly designed primarily to provide free delivery of conditioned air to an enclosed space, room or zone and includes a prime source of refrigeration for heating and which takes its source of air for the evaporator from the conditioned space, and discharges this air through a duct to the outdoor space

Note 1 to entry: Such heat pumps can be constructed to remove heat from the conditioned space and discharge it to a heat sink if cooling and dehumidification are desired from the same equipment. They can also include means for circulating, cleaning, humidifying, ventilating or exhausting air.

3.20

outdoor compartment

compartment where the exhaust air is rejected through the duct of single duct air conditioner

3.21

outdoor exhaust airflow

discharge rate of flow of air from the equipment through the exhaust duct

Note 1 to entry: See Figure 1.

3.22

outdoor heat exchanger

heat exchanger that is designed to transfer heat to the outdoor ambient environment or to remove heat from it

Note 1 to entry: In the case of an air conditioner or heat pump operating in the cooling mode, this is the condenser. In the case of an air conditioner or heat pump operating in the heating mode, this is the evaporator.

3.23

rated frequency

frequency shown on the nameplate of the equipment

3.24

rated voltage

voltage shown on the nameplate of the equipment

3.25

sensible cooling capacity

amount of sensible heat that the equipment can remove from the conditioned space in a defined interval of time

Note 1 to entry: Sensible cooling capacity is expressed in units of watts.

3.26

sensible heat ratio

SHR

ratio of the sensible cooling capacity to the total cooling capacity

3.27

spot cooler

encased assembly air conditioner that lies wholly within a conditioned space and that draws air for both the evaporator and condenser from the conditioned space and expels both of these back into the conditioned space

Note 1 to entry: A spot cooler is usually portable.

3.28

standard air

dry air at 20 °C and at a standard barometric pressure of 101,325 kPa, having a mass density of 1,204 kg/m³

3.29

supplementary water tank

tank designed as an integral part of the unit to contain external supplementary water which is fed to the evaporatively cooled condenser

3.30

total cooling capacity

amount of sensible and latent heat that the equipment can remove from the conditioned space in a defined interval of time

Note 1 to entry: Total cooling capacity is expressed in units of watts.
