� Cooling capacity
Generally, cooling capacity of 1P (horse power) equals to
2000Kcal. According to international standard, cooling capac-
ity of 1P=2000Kcal x 1.162=2324(W). W represents cooling
capacity. Cooling capacity of 1.5P=2000Kcal x 1.5 x 1.
162=3486(W). Therefore, it is easy to determine horse power
of the air conditioner and the cooling capacity. Normally, 1P
product is defined in the range of 2200(W)�2600(W); 3200
(W)�3600(W) for 1.5P; 4500 (W)�5100(W) for 2P. For british
unit, it should be calculated as follows: A(BTU) x 1.06 � 3.
6=B (W). For instance, 18000 (BTU) x 1.06 � 3.6=5300 (W),
that is, 2P air conditioner. In room of 3 meters high and with-
out large heating unit, air conditioner of 1P, 1.5P, 2P, 3P, or
5P is suitably used in areas of 12�18, 20�25, 24�36, 30�
40, 40�60(m2). Increase the cooling capacity accordingly if
height of room exceeds 3 meters or there is frequent person-
nel in and out.

in Zone 1 and Zone 2
Mounting: window type, split wall type, and split tank type.
Ambient temperature groups of T1,T2,T3 are available to
meet different climates all over the world. Ambient tempera-
ture T1 ranges from -7�~43�, Ambient temperature T2
ranges from -7�~35�, Ambient temperature T3 ranges from
-7�~52�, The explosion-proof treatment of products of T1,
T2 groups is based on MITSUBISHI, while that of T3 group
on Carrier. User should choose the proper product accord-
ing to the local ambient temperature.
The product can adjust indoor temperature and filter air
automatically, and provide comfortable environment. Also, it
is used to eliminate humidity and fresh the air. It can be widely
used in explosive gas atmosphere of II A, II B, II C with tem-
perature groups of T1, T2, T3, such as petroleum, chemical,
mine, oil storage, pharmacy, gas station, liquefied gas station,
military facilities, etc..
Product of T1 group is suitable in area with medium tem-
perature while low temperature for T2 product and high for
T3 respectively.
For explosion-proof window air conditioner, the correspond-
ing product is the single cooling air conditioner in T3 group.
For split tank and split wall types, both single cooling and
combined heating and cooling products in T1, T2,and T3 are
available.

Explosion protectionCertificatesConformity to standards
For explosion-proof window air conditioner, the corresponding
product is the single cooling air conditioner in T3 group. It is
mainly used in high temperature areas, such as Middle East,
Africa, South Asia and tropical zone nearby the equator.
Explosion-proof window air conditioner is developed on base of
product of Carrier Brand, by conducting explosion-proof treat-
ment to internal control units, compressor, indoor and outdoor
fan motors, temperature sensor system, protective system, heat-
removal system, cooling system, etc., after which the outline
dimensions and installation are same as the original ones.
The low-temperature low-pressure frigerant within cooling sys-
tem is indrafted by the compressor and compressed to high-
temperature high-pressure gas. It then flows into outdoor heat
exchanger, resulting in liquid condensed by air. Passing through
capillary, it arrives indoor heat exchanger, where it is vaporized,
absorbing heat indoor, and then it is introduced by compressor
again. Thus, indoor temperature will be reduced through this
circulation.
Normally, rated voltage is AC220V/50Hz. Please specify any
special requirements.

For explosion-proof wall air conditioner, both single coolingand combined heating and cooling products in T1, T2,andT3 are available, to meet different requirements of low, me-dium and high temperature zones world wide.Explosiooon-proof wall air conditioner is developed on baseof normal product of MITSUBISHI and Carrier brands, bytaking explosion-proof measures to indoor and outdoor units.Measures to outdoor unit: by taking special technics andcontrol, conduct explosion-proof treatment to internal con-trol units, compressor, outdoor fan motor, protective system,heat-removal system, cooling system, etc. Besides, explo-sion-proof control box and sensor system are coped withintrinsic safety. The outline dimensions and installation arethe same as the original ones after explosion-prooftreatment. Indoor unit: by taking special technics and control,dismantle internal electric control units and re-design to ex-plosion-proof structure which enables seperate explosion-proof control box. Remote controller and sensor system arecoped with intrinsic safety. The outline dimensions and in-stallation are the same as the original ones after explosion-proof treatment.Remote controller provides 3V intrinsic safety power through
