1, state point a1 is air regime in start cup, and identical with outdoor, its dry-bulb temperature, enthalpy, water capacity are respectively 45.0 DEG C, 76.4 kJ/kg, 12.0 g/kg.

2, start after, state be a1 room air to be discharged filtration heat exchanger in equal-enthalpy humidifying to wet-bulb temperature, state becomes b1 point, its dry-bulb temperature, relative humidity, enthalpy, water capacity distinguish 25.7 DEG C, 95%, 76.4 kJ/kg, 19.8 g/kg.The temperature of the filtration heat exchanger of directly contact is with it also close to 25.7 DEG C simultaneously;

3, state is that the outdoor air of a1 enters filtration heat exchanger, be in direct contact with it the wet refrigeration such as heat exchange, temperature drops to close to 25.7 DEG C, becomes state a2 after entering the thermic load in indoor absorption chamber, and temperature about 31 DEG C, enthalpy are that 62.0 kJ/kg, water capacity do not become 12.0 g/kg;

4, the room air of state a2 is more after filtration outside heat exchanger discharge chamber, and in filtration heat exchanger, equal-enthalpy humidifying is to wet-bulb temperature, and state becomes b2 point, and exhaust drops to about 21.9 DEG C with the temperature of filtration heat exchanger;

5, state is that the outdoor air of a1 enters filtration heat exchanger, be in direct contact with it the wet refrigeration such as heat exchange, temperature drops to close to 21.9 DEG C, becomes state a3 after entering the thermic load in indoor absorption chamber, and temperature about 25 DEG C, enthalpy are that 55.8 kJ/kg, water capacity do not become 12.0 g/kg;

6, so constantly circulation, the room air wet cooling such as constantly, state point constantly along etc. wet line move down into a4, a5 ... point, until reach its limiting condition---dew point.

Above ai point is the state variation track of room air when air-conditioning work, ai by a1 along etc. wet line move down, to the last approach dew point.The motion track of ai is made up of a large amount of intensive discrete points, and the air output of air-conditioner is larger, and each circulation temperature lowering is more, and dispersion is higher.Several state points in example are the state points in the optional process for analyzing.

Because relative humidity does not feel like oneself starting more than 70% people, so state a4 can be taken as desirable operating point.This operating mode original state temperature oneself reach the high point of 45.0 DEG C, but only have 12.0 g/kg because of water capacity, after the machine process, still can reach very desirable state.

Usually get on very well, all dew points are lower than 22 DEG C or the water capacity climatic condition lower than 17.0 g/kg, use the machine all can obtain the air-conditioning effect of temperature 26 DEG C, relative humidity about 70%, can replace compressed air conditioner, in China, most regional highest temperature all can meet this condition season.
