is applicable in more large room or space) as the cooling load per
unit working area, and the actual applicable coverage area of the air-conditioner is the result of the
cooling capacity being divided by the cooling load. For example: ASW-H12A4/HSA the cooling
capacity is 3200W, the minimum applicable coverage area is 3200/240=13M
（ about ） , and the
maximum coverage area is 3200/150=21M.

Ordinary family room 170 Hotel room ( close type) 160
Garret family room 220 Hotel room (open type) 140
Ordinary office room 200 Hotel hall 220
Haircutting house or shampoo
Salon 280 Conference room, projection room 320
Front hall of hotel or Interval
room 420 Family living room and dining room 200
Garment shop and Jewelry shop 220 Chess & card playing room and tea room 240
The above is the estimation to the applicable area mainly in according to the cooling capacity. Due to
the available temperature difference and the sense difference by different people to the heat energy, the
quantity of heat load is usually bigger than the one of cooling load per unit applicable area according
to the practice experience, and generally about 180-270W/M.

The time for temperature’s drop and rise:
After an air-circulating all over a room by the air-conditioner, because of a heat temperature difference
12--15
℃
available between the inletting room temperature and evaporating temperature, people may
feel an obvious drop happens to the room temperature. Such as one set of 3.2Kw air-conditioner that is
applied to a room with area 13—21M², height 2.8M will achieve an obvious temperature drop within
（
13—21 M²
）
*2.8M/500M/h=0.0728—0.01176h=4.4—7.1min. However, due to the distinct heat
storing capacity of the wall, window & door, furniture, ornaments etc., the drop of temperature will
take more time and even the temperature of the cooled air may contrarily rise up after having touching
them; In addition, the stable operation of the air-conditioner also need some time since the
refrigeration system just start up. In this case, the above calculation method presented and
recommended as the theory reference only.
⑾
The cable, ammeter and the quantity of electricity consumption
Usually, the electric connecting cables (include the plug cable) are already assembled by the
manufacturers to the air-conditioner system and with no extra cost or labor for users. But the cable
from the socket to the switchboard must be laid out by the user before installation. Since the
air-conditioner is the largest one in consuming electricity among the home appliances, the special and
exclusive circuitry (Direct sourced from the total electrical source), and must be equipped with the
earth lead. The dimensions of the leads are required as the below:
